DETAILED DESCRIPTION OF THE INVENTION
[0039] The technical solution of the invention will be further
described below in conjunction with the specific embodiments and
accompanying drawings of the invention. However, the invention is
not limited to these embodiments.
[0040] It should be noted that all directional indications (such as
"above" "upper", "lower", "left", "right", "front" and "back") in
the embodiments of the invention are merely used to explain
relative positional relations and motions of elements at a specific
pose (as shown in the figures). If the specific pose changes, the
directional indications will change accordingly.
[0041] As shown in FIG. 1 to FIG. 6, the invention provides an
adjustable desk easy to disassemble. The adjustable desk easy to
disassemble comprises: a strip-shaped crossbeam 100 used as a
bearing structure of the adjustable desk; two desk legs 200
disposed at two ends of the crossbeam 100, pivotably connected to
the crossbeam 100 and used to stabilize relative positions of the
desk legs 200 and the crossbeam 100 through first locking parts;
and two brackets 300 disposed at the two ends of the crossbeam 100,
located above the corresponding desk legs 200, and fixed to the
crossbeam 100 through second locking parts. When the adjustable
desk needs to be disassembled, the first locking parts and the
second locking parts are removed, and then the two desk legs 200
are rotated towards each other, so that the adjustable desk is
stored.
[0042] According to the adjustable desk easy to disassemble of the
invention, the adjustable desk can be easily assembled and
disassembled by rotating the two desk legs 200 towards or opposite
to each other by means of the first locking parts and the second
locking parts, and the assembly and disassembly efficiency of the
adjustable desk is improved.
[0043] To further improve the disassembly efficiency of the
adjustable desk, the first locking parts may overlap with the
second locking parts.
[0044] Further preferably, first locking holes 110 are formed in
the crossbeam 100, second locking holes 310 are formed in the
brackets 300, and screws 210 are screwed on the desk legs 200;
wherein, the first locking holes 110 are matched with the screws
210 to form the first locking parts between the crossbeam 100 and
the desk legs 200, and the second locking holes 310 are matched
with the screws 210 to form the second locking parts between the
brackets 300 and the crossbeam 100.
[0045] In this embodiment, the screws 210 between the crossbeam 100
and the desk legs 200 are shared by the brackets 300 and the
crossbeam 100, so that fixing positions between the crossbeam 100
and the desk legs 200 overlap with fixing positions between the
brackets 300 and the crossbeam 100; and the crossbeam 100, the desk
legs 200 and the brackets 300 can be fixed and disassembled
synchronously by rotating the screws 210, so that the disassembly
efficiency of the adjustable desk is further improved.
[0046] Because of the small size of the screws 210, the screws 210
may be lost if they are stored separately after being disassembled
from the desk legs 200 when the adjustable desk is not used (in a
folded state), so a better method for storing the screws 210 is to
keep then screwed on the desk legs 200 all the time. However, if
the screws 210 are always screwed on the desk legs 200, the
crossbeam 100 will be connected to the desk legs 200; or, when the
brackets 300 are connected to the crossbeam 100, the screws 210
need to be unscrewed at first and are then screwed on the desk legs
200 via the first locking holes 110 and the second locking holes
310, which will take a long time; and when the adjustable desk is
assembled and disassembled, the screws 210 have to be placed aside,
which is not beneficial to assembly and disassembly.
[0047] So, to further improve the assembly and disassembly
efficiency of the adjustable desk, the first locking holes 110 and
the second locking holes 310 are of a semi-open structure, that is,
one end of each first locking hole 110 and one end of each second
locking hole 310 are closed, and the other end of each first
locking hole 110 and the other end of each second locking hole 310
are open. Wherein, after the adjustable desk is assembled, both the
first locking holes 110 and the second locking holes 310 are open
toward the desk legs 200.
[0048] In this embodiment, the first locking holes 110 and the
second locking holes 310 are of the semi-open structure, so that
when the desk legs 200 are unfolded or folded, the screws 210
screwed on the desk legs 200 can be synchronously clamped into or
slid out of the first locking holes 110 and the second locking
holes 310 along with the rotation of the desk legs 200, and thus,
the crossbeam 100 and the desk legs 200 can be connected easily,
and the brackets 300 and the crossbeam 100 can be connected
easily.
[0049] Moreover, both the first locking holes 110 and the second
locking holes 310 are open towards the desk legs 200 after the
adjustable desk is assembled, and the screws 210 are clamped in and
matched with the closed ends of the first locking holes 110 and the
closed ends of the second locking holes 310 after the adjustable
desk is assembled, so the bearing capacity of the adjustable desk
is further improved.
[0050] Preferably, corners of the crossbeam 100 are wrapped in the
brackets 300, wherein the second locking holes 310 are farther away
from the desk legs 200 than the first locking holes 110, and the
second locking holes 310 are counter bores.
[0051] In this embodiment, the corners of the crossbeam 100 are
wrapped in the brackets 300, so that both ends and the corners of
the crossbeam 100 are protected; in addition, the second locking
holes 310 are counter bores, so that the end faces of the screws
210 are flush with the surfaces of the brackets 300 when the screws
210 are tightened, and thus, the appearance of the lifting desk is
improved.
[0052] Further preferably, the brackets 300 are L-shaped and each
comprise a horizontal plate 320 and a vertical plate 330, wherein
the horizontal plates 320 are inserted into and matched with the
crossbeam 100, and the second locking holes 310 are located in the
vertical plates 330.
[0053] In this embodiment, the horizontal plates 320 are inserted
into and matched with the crossbeam 100, so that the brackets 300
are accurately positioned when connected to the crossbeam 100, it
is ensured that the second locking holes 310 are coaxial with the
first locking holes 110, the screws 210 can be synchronously
clamped into or slid out of the first locking holes 110 and the
second locking holes 310, the crossbeam 100, the desk legs 200 and
the brackets 300 can be fixed and disassembled rapidly, and thus,
the assembly and disassembly efficiency of the adjustable desk is
further improved.
[0054] Further preferably, insertion plates 340 are mounted on the
horizontal plates 320, and guide slots 120 are formed in the
crossbeam 100, wherein the insertion plates 340 are inserted into
the guide slots 120 to enable the brackets 300 to be inserted into
and matched with the crossbeam 100.
[0055] In this embodiment, the insertion plates 340 are mounted on
the horizontal plates 320, so that the thickness of the horizontal
plates 320 is increased, it is ensured that the horizontal plates
320 of the brackets 300 are located on the same plane as the
crossbeam 100 after the brackets 300 are connected to the crossbeam
100, in this way, the contact area of a desk board with the
brackets 300 and the crossbeam 100 is enlarged, and the bearing
capacity of the whole adjustable desk is improved; in addition, to
guarantee the levelness of the adjustable desk after installation,
notches 180 are formed in openings of the guide slots 120 of the
crossbeam 100 to allow the horizontal plates 320 of the brackets
300 to be mounted therein.
[0056] Preferably, the crossbeam 100 is a frame structure formed by
bending a metal sheet, and a mounting cavity 130 is formed in the
crossbeam 100 in a lengthwise direction of the crossbeam 100;
wherein, the two desk legs 200 are mounted at two ends of the
mounting cavity 130 respectively to be inserted into and matched
with the crossbeam 100, and thus, the degree of freedom of the desk
legs 200 in the vertical direction of the horizontal plane is
limited.
[0057] Further preferably, a motor housing 220 which is embedded in
the mounting cavity 130 and is rotatably connected to a cavity wall
of the mounting cavity 130 is disposed at one end of each desk leg
200 and is connected to the cavity wall of the mounting cavity 130
through a pin 140, and the screws 210 are mounted on the motor
housings 220. One the one hand, the two desk legs 200 can be
rotated towards or opposite to each other through the pins 140; and
on the other hand, the degree of freedom of the desk legs 200 in
the horizontal direction of the horizontal plane is limited by the
pins 140.
[0058] Further preferably, to allow the tightness of the motor
housings 220 and the crossbeam 100 to be adjusted easily to avoid
the situation where the desk legs 200 rotate when the adjustable
desk is assembled or disassembled due to the fact that the pins 140
are too tight or the situation where the motor housings 220 shake
in the mounting cavity 130 due to the fact that the pins 140 are
too loose, adjusting holes 150 are formed in the crossbeam 100 and
correspond to the pins 140 in position, so that users can rotate
the pins 140 correspondingly through the adjusting holes 150 to
adjust the tightness of the motor housings 220 and the crossbeam
100.
[0059] Preferably, because of the large horizontal span of the
crossbeam 100, if the crossbeam 100 is integrally formed by
bending, the manufacturing difficulty of the crossbeam 100 will be
increased, and the manufacturing cost of the crossbeam 100 will be
increased. In view of this, the crossbeam 100 is divided into a
plurality of telescopic tubes 160, each of which is formed by
bending a metal sheet, wherein every two adjacent telescopic tubes
160 are detachably connected. By dividing the crossbeam 100 into a
plurality of telescopic tubes 160, the manufacturing process and
manufacturing cost of the crossbeam 100 are reduced; and on the
other hand, the length of the crossbeam 100 can be adjusted to
adjust the dimensions of the adjustable desk, so that users can
select the dimensions of the desk according to personnel
requirements.
[0060] Further preferably, connecting plates 170 are mounted at the
ends, close to the motor housings 220, of the telescopic tubes 160
and are of an L-shaped structure, wherein one side of each
connecting plate 170 is provided with a guide surface 171 and is
connected to the corresponding notch 180, and the first locking
holes 110 are located in the other side of the connecting plates
170.
[0061] In this embodiment, the brackets 300 can be horizontally
pushed to insert the insertion plates 340 into the guide slots 120
through the guide surfaces 171, so that the connection firmness
between the brackets 300 and the crossbeam 100 is guaranteed.
[0062] The crossbeam 100 is divided into a plurality of telescopic
tubes 160 and every two adjacent telescopic tubes 160 are
detachably connected, so that the strength of the crossbeam 100 is
reduced to some extent. In order to improve the strength of the
crossbeam 100 to prevent the middle of the crossbeam 100 from
bending, a reinforcing plate 190 is mounted at the joint of every
two adjacent telescopic tubes 160 and is of a U-shaped structure,
wherein closed ends of the reinforcing plates 190 are flush with
the horizontal plates 320.
[0063] The operating principle of the adjustable desk easy to
disassemble of the invention is as follows: in general conditions,
the motor housings 220 in the desk legs 200 are always rotatably
connected to the crossbeam 100, so the two desk legs 200 at the two
ends of the crossbeam 100 are cross-stacked in an initial state;
when the adjustable desk needs to be assembled, the crossbeam 100
is turned to face downwards at first, and the two cross-stacked
desk legs 200 face upwards; then, the users pull one desk leg 200
to enable the desk leg 200 to rotate around the pin 140, and when
the desk leg 200 is rotated by a certain angle and the screw 210 on
the motor housing 220 has not been clamped in the first locking
hole 110 in the crossbeam 100, the insertion plate 340 on the
bracket 300 is inserted into the guide slot 120 along the
connecting plate 170, and at this moment, the second locking hole
310 in the bracket 300 is coaxial with the first locking hole 110;
the desk leg 200 is further rotated to enable the screw 210 to be
synchronously clamped in the first locking hole 110 and the second
locking hole 310, and finally, the screw 210 is rotated with a tool
to fixedly connect the crossbeam 100, the desk leg 200 and the
bracket 300; and finally, the adjustable desk is assembled.
[0064] It should be noted that descriptive terms such as "first"
and "second" involved in the invention are only used for the
purpose of description and should not be construed as indicating or
implying relative importance or implicitly indicating the number of
