Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a lavatory
faucet, and more particularly to a structure for locating securely
the water mixing bolt of the lavatory faucet.
[0003] 2. Description of Related Art
[0004] As shown in FIG. 1, a lavatory faucet of the prior art is
fastened with the lavatory basin 16 in conjunction with a cold
water control valve 10 and a hot water control valve 11, which are
connected by a connection pipe 13. The cold water control valve 10
is connected with a cold water pipe 14 while the hot water control
valve 11 is connected with a hot water pipe 15. The water pipes 14
and 15 are respectively put through the mounting hole 17 of the
basin 16 along with a locating board 18, and a locking ring 19. The
faucet neck 20 is fastened with a lug 22 by a fastening bolt 21.
Located between the faucet neck 20 and the basin 16 is a cover
board 23. The locating board 18 and the locking ring 19 are located
at the bottom of the basin 16 such that they can be hardly reached
by hand or hand tool. As a result, it is difficult to loosen the
locking ring 19 so as to separate the faucet neck 20 from the basin
16 in the event that the lavatory faucet is to be replaced.
BRIEF SUMMARY OF THE INVENTION
[0005] The primary objective of the present invention is to provide
a lavatory faucet which can be easily unfastened with a lavatory
basin to which the lavatory basin is fastened.
[0006] The lavatory faucet of the present invention comprises a
water mixing bolt seat, a fastening board, a water mixing bolt
tube, a locating bolt, and a faucet neck. The water mixing bolt
seat is mounted between the cold water control valve and the hot
water control valve along with the fastening board. The water
mixing bolt seat is located securely in place by the fastening
board which is pressed against the lavatory basin. The lavatory
neck is located by the locating bolt.
[0007] The features and the functions of the present invention will
be more readily understood upon a thoughtful deliberation of the
following detailed description of the present invention with
reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
[0008] FIG. 1 shows a sectional schematic view of a lavatory faucet
of the prior art mounted on the lavatory.
[0009] FIG. 2 shows a perspective view of a lavatory faucet of the
present invention.
[0010] FIG. 3 shows an exploded view of the lavatory faucet of the
present invention.
[0011] FIG. 4 shows a side sectional view of the lavatory faucet of
the present invention in combination.
[0012] FIG. 5 shows a front sectional view of the lavatory faucet
of the present invention in combination.
DETAILED DESCRIPTION OF THE INVENTION
[0013] As shown in FIGS. 2-5, a lavatory faucet of the present
invention comprises a water mixing bolt seat 40, a fastening board
50, a water mixing bolt tube 60, a locating bolt 70, and a faucet
neck 80.
[0014] The water mixing bolt seat 40 is mounted on a connection
pipe 31 which is connected with a cold water control valve 30 and a
hot water control valve 301. The water mixing bolt seat 40 is
provided at the top end with a receiving hole 41. The connection
pipe 31 is provided with a lug 43 which is corresponding in
location to the water mixing bolt seat 40 and is provided with a
through hole 42. The water mixing bolt seat 40, the connection pipe
31, and the lug 43 of the connection pipe 31 are made integrally
such that the receiving hole 41 of the water mixing bolt seat 40 is
in communication with the connection pipe 31.
[0015] The fastening board 50 is provided with a first through hole
51 with inner threads 53, and a second through hole 52. The
fastening board 50 is disposed over the water mixing bolt seat 40
such that the first through hole 51 is in alignment with the
receiving hole 41 of the water mixing bolt seat 40, and that the
second through hole 52 is aligned with the through hole 42 of the
lug 43 of the connection pipe 31.
[0016] The water mixing bolt tube 60 is provided with an outer
threaded segment 62, and a longitudinal through hole 63 which is
provided at the top end with a fitting slot 64 engageable with a
hand tool. The water mixing bolt tube 60 is put through a mounting
hole "B" of the lavatory basin "A" such that the bottom end of the
water mixing bolt tube 60 is received in the receiving hole 41 of
the water mixing bolt seat 40 via the first through hole 51 of the
fastening board 50, and that the outer threaded segment 62 of the
water mixing bolt tube 6o is engaged with the inner threads 53 of
the first through hole 51 of the fastening board 50. As the water
mixing bolt tube 60 is turned by the hand tool engaging the fitting
slot 64 of the tube 60, the fastening board 50 is moved upwards to
press against the bottom edge of the mounting hole "B" of the
lavatory basin "A". The tube 60 is provided at both longitudinal
ends with a plurality of washers 61.
[0017] The locating bolt 70 has a head 71, a threaded shank 72, a
retaining groove 73 located between the head 71 and the shank 72,
and a longitudinal through hole 75. The through hole 75 is provided
in one end with a fitting slot 77 opposite in location to the head
71 and engageable with a hand tool. A lift rod 76 of the lavatory
basin "B" is put through the through hole 75 of the locating bolt
70. The locating bolt 70 is received in the through hole 42 of the
lug 43 of the connection pipe 31 in conjunction with a retaining
ring 74 which is retained in the retaining groove 73 of the
locating bolt 70.
[0018] The faucet neck 80 is provided in the bottom end with a
connection slot 81, a locating slot 82 with inner threads 84, and a
water discharging duct 83 in communication with the connection slot
81. The faucet neck 80 is mounted on the lavatory basin "A" such
that the inner threads 84 of the locating slot 82 are engaged with
the threaded shank 72 of the locating bolt 70, and that the top end
of the water mixing bolt tube 60 is received in the connection slot
81 of the faucet neck 80, and further that the water discharging
duct 83 of the faucet neck 80 is in communication with the
connection slot 81 and the longitudinal through hole 63 of the
water mixing bolt tube 60.
[0019] The lavatory faucet of the present invention can be easily
removed from the lavatory basin by a hand tool, which is engaged
with the fitting slot 77 of the locating bolt 70 and the fitting
slot 64 of the water mixing bolt tube 60.
[0020] The present invention described above is to be regarded in
all respects as being merely illustrative and not restrictive.
Accordingly, the present invention may be embodied in other
specific forms without deviating from the spirit thereof. The
present invention is therefore to be limited only by the scope of
the following claim.
