Description
RELATED APPLICATIONS
[0001] This application claims priority to Chinese patent
application number 201910911493.7, filed on Sep. 25, 2019. Chinese
patent application number 201910911493.7 is incorporated herein by
reference.
FIELD OF THE DISCLOSURE
[0002] The present disclosure relates to a fixing device, and in
particular relates to a fixing device and a faucet installation
device.
BACKGROUND OF THE DISCLOSURE
[0003] CN206607638U discloses a fixing device for fixing bathroom
fixtures. A fixing base of the fixing device has a bolt opening,
reverse holding elements, and a fixing bolt. The reverse holding
elements are respectively configured to be attached to an inner
side of the fixing base, and the fixing bolt is inserted through
the bolt opening. A head of the fixing bolt is kept in this
position and a rear side of the fixing bolt is obliquely screwed
into the reverse holding elements. When the fixing device is
assembled, an assembly free space is formed between the
corresponding bolt opening and the inserted fixing bolt. Therefore,
the reverse holding elements pre-assembled at the fixing bolt can
move towards each other into an assembly position when the fixing
bolt inclines, and the reverse holding element couples with and
passes through the fixing opening in the assembly position. In
addition, the fixing device comprises a flexible bow that connects
at least two of the reverse holding elements in such a way that the
reverse holding element itself can move back from the reverse
holding position into the assembly position. Because the flexible
bow is made of a flexible material, the deformation of the flexible
bow needs to be manually controlled during assembly to enable the
flexible bow to pass through a mounting hole of a countertop.
Further, two ends of the flexible bow may be elastically deformed,
thereby making it difficult to ensure that the two ends of the
flexible bow are on a same plane and locked under the countertop,
and therefore the connection strength is not high. The technical
solution of JP4968629B2 also has the above-mentioned
shortcomings.
[0004] CN208152161U discloses a quick installation structure on a
faucet countertop, comprising a fixing base with a diameter larger
than the mounting hole of the countertop, a locking mechanism, and
a bolt. The fixing base is disposed with an installation channel
for pipes to pass through and an installation hole for bolts to
pass through. An outer circumference of the fixing base is matched
with a valve body of the faucet. The fixing base is also provided
with a limit mechanism for restricting rotation of the locking
mechanism. The locking mechanism comprises a bracket that can pass
through the mounting hole of the countertop and at least one
elastic mechanism rotatably arranged on one side of the bracket.
The bracket is provided with a bolt hole matched with the bolt. One
end of the limit mechanism is connected to the fixing base, and the
other end of the limit mechanism is connected to the bracket. In
this technical solution, the bracket and the fixing base are
connected by the bolt to be clamped to the countertop to achieve a
fixed connection. As the locking mechanism and the fixing base are
only connected by a bolt and the elastic mechanism is connected to
the bracket, the elastic mechanism is driven by the bracket and is
pressed under the countertop. In an actual connection process, it
is impossible to ensure that the elastic mechanism and the bracket
are tightly pressed against the countertop, so the connection
strength is not high.
[0005] CN208169679U discloses a faucet base installed on a
countertop. The faucet base comprises a base body arranged on the
mounting hole of the countertop and used for fixing a faucet. The
faucet base also comprises a guide column, a blocking block, a
screw, and a locking block. An upper end of the guide column is
fixed with the base body, and the base body is provided with a
first through hole. The screw can rotatably penetrate the first
through hole, and an upper end of the screw is disposed with a nut.
The blocking block can be moved up and down through the guide
column, the locking block is screwed on the screw. When the screw
rotates in a first direction, the locking block is blocked at a
first position by the blocking block, and the locking block and the
blocking block move away from the base body. When the screw moves
in a second direction, the locking block is blocked by the blocking
block in a second position, and the locking block and the blocking
block move close to the base body until the locking block is locked
under the countertop. When the locking block is in the first
position, the guide column, the blocking block, the screw, and the
locking block form a hole having a maximum outer diameter that is
smaller than a diameter of the mounting hole. In this technical
solution, the screw not only constitutes a rotation shaft
connecting the blocking block and the locking block, but the screw
also connects the blocking block, the locking block, and the base
body to be clamped to the countertop to achieve a fixed connection.
However the faucet base is only connected by the screw, and the
screw is connected to ends of the blocking block and the locking
block, so the connection strength is not high.

pressing plate against a back of the fixed object, which can
enhance the connection strength. Each pressing plate has at least
two stress points. One stress point is the connection of the
locking rod, and the other stress point is the connection of the
two pressing plates. The two pressing plates can therefore have
three stress points forming a triangular structure, and the
connection strength is stable and reliable and the triangular
structure can also help to avoid deformation of the pressing plate
due to stress.
[0040] The first locking rod can move relative to the base between
the working state and the movable state. When in the working state,
the first locking rod is connected to the first connecting base.
The second locking rod is connected to the second connecting base
and is always in working state. The disassembly is convenient.
[0041] The two locking rods can move relative to each other so that
the two locking rods can move when the pressing block mechanism
changes between the unfolded state and the folded state. The two
locking rods can be driven to move through the change of the
pressing block mechanism, or the movement of the two locking rods
drive the change of the pressing block mechanism. Therefore, the
assembly and the disassembly is convenient.
[0042] At least one part of the movement track of at least one
locking rod relative to the base is located in a plane
perpendicular to the first direction, so that the two locking rods
can move when the pressing block mechanism changes between the
unfolded state and the folded state. The change of the pressing
block mechanism drives the at least one locking rod to move, or the
change of the pressing block mechanism is driven by the movement of
the at least one locking rod. Therefore, the assembly and the
disassembly is convenient.

define two connecting bases 11 and 12. Positions of the two
connecting bases 11 and 12 are radially and symmetrically arranged,
and an outer diameter of the sleeve is larger than an inner
diameter of the through hole. The two connecting bases 11 and 12
define a first connecting base 11 and a second connecting base 12,
respectively. The first connecting base 11 comprises an inlet slot
111 penetrating in the first direction, and an opening of the inlet
slot 111 is disposed on an outer side wall of the first connecting
base 11 to enable a first locking rod 31 to be disposed in the
inlet slot 111 from an outer side of the inlet slot 111 in an inner
side of the sleeve. The second connecting base 12 comprises a
connecting hole 121 penetrating in the upper and lower direction
(i.e., in the first direction).
[0060] The pressing block mechanism 2 comprises two pressing plates
21. The two pressing plates 21 are rotatably connected together to
enable the pressing block mechanism 2 to change between an unfolded
state and a folded state. A rotation axis of the two pressing
plates 21 is in the first direction, and outlines of the pressing
block mechanism 2 in the unfolded state and the folded state are
different. An area of the outline of the pressing block mechanism 2
in the unfolded state is larger than an area of the outline of the
pressing block mechanism 2 in the folded state to enable the
pressing block mechanism 2 in the folded state to freely pass
through the through hole of the countertop C and to enable the
pressing block mechanism 2 in the unfolded state not to pass
through the through hole of the countertop C.
[0061] The two pressing plates 21 are respectively connected with
two locking rods 31 and 32. Each of the two locking rods 31 and 32
is a screw rod and comprises a screw head 33 and a threaded
portion. The two locking rods 31 and 32 define the first locking
rod 31 and a second locking rod 32, respectively. The threaded
portion of the first locking rod 31 is screwed to one of the two
pressing plate 21, and the first locking rod 31 is configured to
move relative to the base 1 between a working state (i.e., a
working position) and a movable state (i.e., a movable position).
The first locking rod 31, when in the working state, is connected
to the first connecting base 11, and the first locking rod 31, when
in the working state, is disposed in of the inlet slot 111. As
required, the first locking rod 31, when in the working state, can
be disposed in a whole of the inlet slot 111 or a deepest part of
the inlet slot 111. Since the first locking rod 31 is configured to
move relative to the base 1 between the working state and the
movable state, the movement of the first locking rod 31 comprises
movement along a plane perpendicular to the first direction. That
is, the first locking rod 31 is configured to move relative to the
base 1 in a horizontal direction. The threaded portion of the
second locking rod 32 is screwed to the other one of the two
pressing plates 21, and the second locking rod 32 passes through
the connecting hole 121 of the second connecting base 12. That is,
the second locking rod 32 always remains in a working state. With
respect to the two locking rods 31 and 32, the first locking rod 31
is configured to move in the horizontal direction, so that the
first locking rod 31 moves between the working state and the
movable state to drive the pressing block mechanism 2 to change
between the unfolded state and the folded state.
[0062] The screw heads 33 of the two locking rods 31 and 32, when
in the working state, abut top surfaces of the two connecting bases
11 and 12. The threaded portions of the two locking rods 31 and 32
are screwed to the two pressing plates 21, and the two locking rods
31 and 32 rotate to drive the two pressing plates 21 to move
upward. That is, a distance between the two pressing plates 21 and
the base 1 can be controlled, and the two pressing plates 21 and
the base 1 are configured to be clamped to the countertop C to
achieve a fixed connection due to the two locking rods 31 and
32.
[0063] In this embodiment, the two pressing plates 21 comprise
locking holes 211, and inner sides of the two pressing plates 21
are embedded with nuts 22. Each of the nuts 22 is aligned with a
corresponding the locking hole 211. The threaded portions of the
two locking rods 31 and 32 are screwed to the nuts 22. In some
embodiments, side walls of the two pressing plates 21 extend inward
to define mounting grooves 212 in communication with the locking
holes 211, and the nuts 22 are disposed in the mounting grooves
212. The mounting grooves 212 are configured to restrict axial
positioning and rotation of the nuts 22 to facilitate processing
and assembly and to enhance threaded connection strength. Positions
of the nuts 22 of the two pressing plates 21 are staggered in the
first direction to facilitate assembly, compact the structure, and
provide more space for an installation of a water pipe of the
faucet A.
[0064] In this embodiment, the fixing device B further comprises a
rotation shaft 23, and the two pressing plates 21 are rotatably
connected together by the rotation shaft 23. In some embodiments,
each of the two pressing plates 21 comprises a semicircular plate,
and two arc ends of the semicircular plate define a first end and a
second end, respectively. The rotation shaft 23 is connected to the
first ends of the two pressing plates 21, and the two locking rods
31 and 32 are respectively connected to the second ends of the two
pressing plates 21. A connection strength between the two locking
rods 31 and 32 and the two pressing plates 21 is enhanced to ensure
the two pressing plates 21 tightly abut a lower side of the
countertop C to improve a connection strength and to facilitate the
first locking rod 31 moving to drive the pressing block mechanism 2
to change between the unfolded state and the folded state.
Moreover, the configuration provides more space for the
installation of the water pipe of the faucet A. Further, the first
end of one pressing plate 21 of the two pressing plates 21
protrudes to define a protrusion 213, and the first end of the
other pressing plate 21 of the two pressing plates 21 extends
inward to define a coupling groove 214. The protrusion 213
cooperates with and is disposed in the coupling groove 214. The
rotation shaft 23 passes through the first end of the other
pressing plate 21 and the protrusion 213 to enhance the connection
strength between the two pressing plates 21, compact the structure,
and provide more space for the installation of the water pipe of
the faucet A. As needed, one end of the rotation shaft 23 is fixed
with a plug, and the other end of the rotation shaft 23 cooperates
with a buckle 231 to enable the rotation shaft 23 to be rotatably
connected to the two pressing plates 21. In some embodiments,
surfaces of the semicircular plates of the two pressing plates 21
facing each other extend inward to define given spaces 24 to
provide a larger space for the installation of the water pipe of
the faucet A.
[0065] In this embodiment, each of the two pressing plate 21
comprises a pressing block 215 and an anti-skid pad 216 fixedly
disposed on the pressing block 215. End surfaces of the two
anti-skid pads 216 are aligned to ensure that the two pressing
plates 21 tightly abut the countertop C, so that a friction
coefficient between the two anti-skid pads 216 and the countertop C
is increased, a friction force is increased, and a connection
strength is increased. In some embodiments, top surfaces of the
pressing blocks 215 extend inward to define slots, and lower ends
of the two anti-skid pads 216 are disposed with posts 217. The
posts 217 couple with and are disposed in the slots. The anti-skid
pads 216 surround outer sides the two locking rods 31 and 32.
[0066] The base 1 is fixedly assembled to the faucet A. For
example, a bottom portion of the faucet A cooperates with and is
disposed in the base 1. A screw A5 is configured to enable the base
1 to be fixedly assembled to the faucet A. The faucet A is fixedly
disposed on the countertop C through the fixing device B.
[0067] An assembly method of the faucet installation device is as
follows. Step 1, referring to FIG. 3, the pressing block mechanism
2 is in the folded state, and the pressing block mechanism 2 passes
through the through hole of the countertop C in a downward
direction. Step 2, referring to FIG. 4, the second locking rod 32
moves to enable the second locking rod 32 and the first locking rod
31 to be unfolded, and the first locking rod 31 moves to drive the
two pressing plates 21 of the pressing block mechanism 2 to be
unfolded. The first locking rod 31, when in the working state, is
disposed in the inlet slot 111, the two pressing plates 21 of the
pressing block mechanism 2 are in the unfolded state. Step 3,
referring to FIG. 5, the first locking rod 31 is tightened. Step 4,
referring to FIG. 6, the second locking rod 32 is tightened. Step
5, referring to FIG. 7, water pipes A7 pass through the faucet
installation device, and the water pipes A7 are in communication
with the control valve A6. Step 6, referring to FIG. 8, the faucet
a surrounds an outer side of the base 1. Step 7, referring to FIG.
9, the base 1 is locked to the faucet A through the screw A5.
Compared with traditional installations, the faucet installation
device of the present disclosure can be installed on the countertop
C directly, and the user need not lie on the ground for
installation. The simple installation method gives a better user
experience. Further, stress points of the two pressing plates 21 of
the pressing block mechanism 2 comprise the second ends of the two
pressing plates 21 respectively connected to the two locking rods
31 and 32 and the first ends of the two pressing plates 21
connected to the rotation shaft 23. That is, the stress points of
the pressing block mechanism 2 comprise the three positions, the
three positions define a triangular structure, so the fixing device
B can endure greater rotation torque and push-pull torque to ensure
installation stability. Moreover, a three-point surface is the most
reliable. In this embodiment, F (left and right rotation
torque).gtoreq.4.5 N.M (Newton-meter); F (forward and backward
push-pull torque).gtoreq.16.5 N.M. Still further, in this
embodiment, the faucet installation device has a larger scope of
application. With respect to kitchen faucets, three hoses with
joints (i.e., a diameter of 10 mm, and a size of 3/8 inch) (D2 in
FIG. 12) and a drawing pipe with an outer diameter of 20 mm (D1 in
FIG. 12) pass through the faucet installation device. Also, two
hoses with joints (i.e., a size of G1/2) pass through the faucet
installation device. According to basin faucets, two hoses with
joints (i.e., a diameter of 10 mm, a size of 3/8 inch) pass through
the faucet installation device.
[0068] A disassembly method of the faucet installation device is as
follows. Step 1, loosening the screw A5 locked to the base 1 and
the faucet A. Step 2, taking out the faucet A. Step 3, removing the
hoses (i.e., the water pipes A7). Step 4, loosening the second
locking rod 32. Step 5, loosening the first locking rod 31. Step 6,
moving the first locking rod 31 to the movable state to drive the
pressing block mechanism 2 to be in the folded state. Step 7,
taking out the pressing block mechanism 2 from the through hole of
the countertop C and taking out a basin. The disassembly method is
simple and convenient to provide the user with a better
experience.
[0069] The fixing device B of this embodiment has the following
advantages. First, the fixing device B is not limited by a height
of the basin and has strong torsion strength and push-pull
strength, provides a large space for pipes to pass through, and can
achieve quick assembly and quick disassembly. Second, the structure
is simple, and the assembly is easy. Third, the components are few,
the structure is stable, and the fixing device B has cost
advantages. Fourth, the space is large (such that the three hoses
with joints (i.e., a diameter of 10 mm, a size of 3/8 inch) and the
drawing pipe with the outer diameter of 18 mm can be fit therein).
Fifth, development cost is reduced.
[0070] FIGS. 13 and 14 are schematic views of the two basin faucets
using the fixing device B.
[0071] The aforementioned embodiments are merely some embodiments
of the present disclosure, and the scope of the disclosure of is
not limited thereto. Thus, it is intended that the present
disclosure cover any modifications and variations of the presently
presented embodiments provided they are made without departing from
the appended claims and the specification of the present
disclosure.
