Description

Technical Field

[0001] This application belongs to the field of desk design technology, and more specifically, relates to a height-adjustable desk. Background Technology

[0002] A desk is a table used for studying and working. Depending on the user, it can be divided into study desks and office desks. Generally, office desks are more targeted, with a relatively fixed user group, so the appropriate height is chosen based on the user's specific needs when purchasing one. However, for study desks, children and teenagers' heights change rapidly with age, and traditional children's and teenagers' desks may become unusable after 1 to 2 years due to unsuitable height, resulting in a waste of resources.

[0003] Most existing height-adjustable desks are fixed with screws, requiring tools and disassembly / reassembly for adjustment, which is complicated and laborious. Furthermore, each adjustment has a limited range, with a relatively large adjustment increment, making it impossible to achieve a height perfectly suited to everyone.

[0004] Therefore, in order to solve the above-mentioned technical problems, finding a height-adjustable table that can be used simultaneously by two people of different heights has become an important research topic for people in this technical field. Summary of the Invention

[0005] The purpose of this application is to provide a height-adjustable desk to solve the technical problem mentioned in the background art that traditional study desks cannot meet the needs of two people of different heights to use at the same time, resulting in a waste of resources.

[0006] To achieve the above objectives, the technical solution adopted in this application is: a height-adjustable desk, comprising:

[0007] The table legs are fitted with support plates fixedly connected to their inner sides.

[0008] A desk drawer is slidably connected to the table legs, and a tabletop is fixedly connected to the desk drawer.

[0009] A lifting assembly is disposed between the support plate and the tabletop. The lifting assembly is used to adjust the desk drawer to slide along the height direction of the table legs in order to raise or lower the desk drawer.

[0010] Preferably, the lifting assembly includes:

[0011] The connecting rod base is fixedly connected to the support plate;

[0012] The first slider is slidably connected to the tabletop;

[0013] The second slider is slidably connected to the tabletop;

[0014] The first connecting rod has one end hinged to the connecting rod base and the other end hinged to the first slider;

[0015] The second connecting rod has one end hinged to the connecting rod base and the other end hinged to the second slider;

[0016] The drive assembly is mounted on the tabletop and is screwed to both the first slider and the second slider.

[0017] Preferably, the driving component includes:

[0018] Two bearing seats, both of which are fixedly connected to the tabletop;

[0019] A bidirectional threaded rod is rotatably connected to the two bearing seats, and the first slider and the second slider are both screwed to the bidirectional threaded rod.

[0020] A drive handle is fixedly connected to one end of the bidirectional threaded rod.

[0021] Preferably, the first slider and the second slider are symmetrically arranged about the connecting rod base.

[0022] Preferably, a slide rail is fixedly connected to the tabletop, and both the first slider and the second slider are provided with slide grooves that are compatible with the slide rail. The first slider and the second slider are slidably connected to the slide rail through the slide grooves.

[0023] Preferably, the inner side of the desk drawer is symmetrically provided with sliding joints, and the desk legs are provided with guide joints adapted to the sliding joints, the guide joints being slidably connected to the sliding joints.

[0024] Preferably, wear-resistant rubber pads are installed at the contact points between the table legs and the ground.

[0025] Preferably, a back cover is also fixedly connected to the tabletop, and the back cover prevents the lifting assembly from being exposed.

[0026] The beneficial effects of the height-adjustable desk provided in this application are as follows:

[0027] 1. When the desk height needs to be adjusted, to raise the desk, the user rotates the drive handle clockwise to rotate the bidirectional threaded rod clockwise. The first and second sliders, which are threaded to the bidirectional threaded rod, move towards each other. Since the support plate is fixedly connected to the two desk legs, and the connecting rod base is fixed to the support plate, with one end of the first connecting rod hinged to the connecting rod base and the other end hinged to the first slider, and one end of the second connecting rod hinged to the connecting rod base and the other end hinged to the second slider, the movement of the first and second sliders towards each other pushes the desk upwards via the first and second connecting rods, causing the desk drawer to move upwards along the guide portion of the desk legs, thus raising the desk. To lower the desk height, the user rotates the drive handle counterclockwise to rotate the bidirectional threaded rod counterclockwise. The first and second sliders, which are threaded to the bidirectional threaded rod, move in opposite directions. Under the action of the first and second connecting rods, the desk drawer moves downwards along the guide portion of the desk legs, thus lowering the desk height. Attached Figure Description

[0039] Please refer to the following: Figures 1 to 4 The present application will now describe a height-adjustable desk provided in an embodiment.

[0040] The height-adjustable desk includes table legs 1, a seat / book drawer 2, and a height-adjusting assembly. Specifically, there are two table legs 1, with a support plate 101 welded and fixedly connected between them. Each table leg 1 has a wear-resistant rubber pad 102 installed at its contact point with the ground. The wear-resistant rubber pad 102 protects the ground, reduces noise, and increases the stability of the desk. The wear-resistant rubber pad 102 is made of natural rubber, synthetic rubber (such as styrene-butadiene rubber, neoprene rubber, ethylene propylene rubber, etc.), or thermoplastic elastomers. Each table leg 1 has a guide portion 103 along its height direction. The inner side of the desk drawer 2 is symmetrically provided with sliding joints 201. The table leg 1 is provided with a guide joint 103 adapted to the sliding joint 201. The guide joint 103 is slidably connected to the sliding joint 201. The table board 9 is fixedly connected to the desk drawer 2. The lifting component is provided between the support plate 101 and the table board 9. The lifting component is used to adjust the desk drawer 2 to slide along the height direction of the table leg 1, so as to achieve the purpose of raising and lowering the desk drawer 2.

[0041] The specific lifting assembly includes: a connecting rod base 3, which is fixedly connected to the center of the support plate 101; a slide rail 8 is fixedly connected to the tabletop 9, which can be fixed by adhesive or screws; the first slider 5 and the second slider 7 are both provided with slide grooves adapted to the slide rail 8, and the first slider 5 and the second slider 7 are slidably connected to the slide rail 8 through the slide grooves; a first connecting rod 4, one end of which is hinged to the connecting rod base 3 and the other end is hinged to the first slider 5; a second connecting rod 6, one end of which is hinged to the connecting rod base 3 and the other end is hinged to the second slider 7, and the first slider 5 and the second slider 7 are symmetrically arranged about the connecting rod base 3 so that the first connecting rod 4 and the second connecting rod 6 are also symmetrically arranged about the connecting rod base 3 so that the force distributed on the first connecting rod 4 and the second connecting rod 6 is relatively uniform during use; and a drive assembly, which is installed on the tabletop 9 and screwed to both the first slider 5 and the second slider 7. The specific drive assembly includes: two bearing seats 10 fixedly connected to the tabletop 9, which can be glued or screwed to the tabletop 9; a bidirectional threaded rod 11 rotatably connected to the two bearing seats 10 via bearings; the first slider 5 and the second slider 7 are both screwed to the bidirectional threaded rod 11, and it should be noted that the thread direction of the bidirectional threaded rod 11 is opposite to that of the screwed sections of the first slider 5 and the second slider 7; a drive handle 12 is fixedly connected to one end of the bidirectional threaded rod 11, and the user drives the bidirectional threaded rod 11 to rotate clockwise or counterclockwise through the drive handle 12, so that the first slider 5 and the second slider 7 move towards or away from each other at the same time, and the sliding part 201 on the desk drawer 2 and the guide part 103 on the table leg 1 slide up or down in the height direction through the first connecting rod 4 and the second connecting rod 6 to adjust the height of the desk. To prevent the lifting assembly from being exposed, a back cover 13 is fixedly connected to the tabletop 9. The back cover 13 does not contact the lifting assembly or the support plate 101. To avoid obstructing the lifting of the desk drawer 2, the bottom of the back cover 13 is hollow. One end of the bidirectional threaded rod 11 passes through the side of the back cover 13 and extends to the outside of the back cover 13, where it is fixedly connected to the drive handle 12.

[0042] Principle: When the desk height needs to be adjusted, such as raising the desk, the user rotates the drive handle 12 clockwise to drive the bidirectional threaded rod 11 to rotate clockwise. This causes the first slider 5 and the second slider 7, which are threaded onto the bidirectional threaded rod 11, to move towards each other. Since the support plate 101 is fixedly connected to the two desk legs 1, and the connecting rod base 3 is fixed to the support plate 101, with one end of the first connecting rod 4 hinged to the connecting rod base 3 and the other end hinged to the first slider 5, and one end of the second connecting rod 6 hinged to the connecting rod base 3 and the other end hinged to the second slider 7, the... When slider 5 and slider 7 move towards each other, they push the tabletop 9 upward through the first connecting rod 4 and the second connecting rod 6, causing the desk drawer 2 to move upward along the guide part 103 of the table leg 1, thereby raising the desk. When it is necessary to lower the desk height, the user drives the bidirectional threaded rod 11 to rotate counterclockwise by turning the drive handle 12. At this time, the first slider 5 and slider 7, which are screwed to the bidirectional threaded rod 11, move in opposite directions. Under the action of the first connecting rod 4 and the second connecting rod 6, the desk drawer 2 moves downward along the guide part of the table leg 1, thereby lowering the desk height.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
