Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that, in the embodiment of the present utility model, directional indications (such as up, down, left, right, front, rear, top, bottom, inner, outer, vertical, lateral, longitudinal, counterclockwise, clockwise, circumferential, radial, axial … …) are referred to, and the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.

As shown in fig. 1-4, a desk lifting mechanism comprises a desk top 1, a bookshelf 2, two supporting side plates 3 and two lifting desk legs 4, wherein the desk top is arranged above the desk legs, the desk legs 4 comprise an outer pipe 41 and an inner pipe 42 which moves up and down relative to the outer pipe, the supporting side plates are connected with the outer pipe of the desk legs, and the bookshelf is arranged between the two supporting side plates; the pipe body 5 is sleeved in the inner pipe, the bottom of the pipe body is connected with the outer pipe, and a threaded nut 6 is arranged in the upper part of the pipe body; a gear box 7 is also arranged between the inner tube and the tabletop plate, a gear box 8 is arranged in the gear box, a first bevel gear 81, a second bevel gear 82, a third bevel gear 83 and a bearing which are mutually meshed are arranged in the gear box, the second bevel gear is provided with a connecting rod 9 which penetrates through the gear box and synchronously links with the gear box of the other tabletop leg, and a screw rod 10 which penetrates through the gear box is arranged in the third bevel gear in a extending manner and is screwed into a nut of the tube body; the first bevel gear and a rocker 11 penetrating through the gear box are arranged in a extending mode in the direction of a user, and the rocker drives the second bevel gear and the third bevel gear to synchronously rotate when driving the first bevel gear to rotate. The rocker is arranged to drive the first bevel gear to rotate, the second bevel gear and the third bevel gear are driven to synchronously rotate, the third bevel gear drives the screw rod, the screw rod and a nut installed in the pipe body are in threaded connection so as to move up and down, the gear box drives the inner pipe to move up and down relative to the pipe body and the outer pipe, the lifting of the tabletop can be adjusted, the other tabletop leg is linked through the second bevel gear and the connecting rod to keep synchronous lifting, the stability of the lifting process is improved, meanwhile, the bookshelf is connected with the outer pipe of the tabletop leg through the two supporting side plates, and therefore the tabletop can be lifted or lowered relative to the bookshelf and the stability of the whole tabletop can be guaranteed.
