DETAILED DESCRIPTION OF THE INVENTION

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.


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.


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.


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.


To further improve the disassembly efficiency of the adjustable desk, the first locking parts may overlap with the second locking parts.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.
