[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model discloses a height-adjustable office desk, according to the attached... Figure 1-3 As shown, the support frame includes a support frame 1, a desktop 2 is mounted on the top of the support frame 1, slots 11 are symmetrically opened on both sides of the support frame 1, and support rods 21 are symmetrically mounted on the bottom of the desktop 2. The two support rods 21 are respectively inserted into the inner walls of the two slots 11. A positioning unit 3 is provided on the front of the support frame 1. The positioning unit 3 includes two positioning seats 31, two pressing blocks 32 and a linkage rod 37. The two positioning seats 31 are symmetrically fixedly installed on the front of the support frame 1. The two pressing blocks 32 are slidably disposed inside the two positioning seats 31. The linkage rod 37 is disposed between the two positioning seats 31 and can simultaneously press and fix the two support rods 21 by the two pressing blocks 32.

[0024] Two support rods 21 are respectively inserted into the inner walls of two slots 11, enabling continuous fine-tuning of the height of the desktop 2 to meet the personalized needs of different users. The structure of the support rods 21 being pressed by double-sided pressing blocks 32 simultaneously ensures uniform force distribution, avoiding wobbling caused by single-point force. At the same time, the linkage rod 37 can simultaneously press and fix the two support rods 21 by the two pressing blocks 32, making it more convenient to adjust them.

[0025] According to the appendix Figure 3 As shown, a slot is further provided between the positioning seat 31 and the support frame 1, and the slot is connected to the slot 11. The pressing block 32 is slidably disposed on the inner wall of the slot.

[0026] A limiting groove is provided on the inner wall of the empty groove, and a limiting block is fixedly connected to the outer wall of the extrusion block 32, and the limiting block is slidably disposed on the inner wall of the limiting groove.

[0027] The cooperation between the limiting block and the limiting groove restricts the movement trajectory of the extrusion block 32, ensuring that it only slides along the axial direction of the threaded rod 33, avoiding deviation caused by lateral force, thereby ensuring the stability of the extrusion effect.

[0028] The end of the extrusion block 32 away from the support rod 21 is fixedly connected to a threaded rod 33, and a nut 34 is threadedly connected to the outer side of the threaded rod 33. The nut 34 is rotatably connected to the inner wall of the positioning seat 31.

[0029] A worm gear 35 is fixedly connected to the side of the nut 34. The worm gear 35 is movably sleeved on the outside of the threaded rod 33, and the worm gear 35 is engaged with the worm 36.

[0030] The two ends of the linkage rod 37 extend into the two positioning seats 31 and are fixedly connected to the ends of the two worm gears 36.

[0031] One of the worm gears 36 extends outward and is fixedly connected to a knob.

[0032] Detailed explanation of the height adjustment process

[0033] Unlock: Rotate the knob in the opposite direction. The worm 36 drives the worms 36 on both sides to rotate synchronously through the linkage rod 37. The worm wheel 35 drives the nut 34 to rotate. The threaded rod 33 drives the extrusion block 32 to slide away from the support rod 21 along the limiting groove. The extrusion block 32 disengages from the support rod 21, and the support rod 21 can slide freely in the slot 11.

[0034] Manually raise or lower the tabletop 2, and the support rod 21 moves up and down within the slot 11 to the target height. Turn the knob forward, and the worm gear 36 drives the worm wheel 35 and nut 34 to rotate. The threaded rod 33 pushes the pressing block 32 to slide along the limiting groove toward the support rod 21. The pressing block 32 fits tightly against the surface of the support rod 21, locking the position of the support rod 21 through friction.

[0035] Due to the self-locking characteristics of the worm gear 35 and worm 36, even if the desktop 2 is subjected to an external force in the vertical direction, it cannot drive the worm 36 in the reverse direction, ensuring a stable locked state.
