The overturning device comprises a tabletop support, a driving device, a lead screw, a hand-cranking tabletop overturning adjustment handle, a tabletop supporting rod, a sliding way and a detachable threaded slider, the tabletop supporting rod is connected with the detachable threaded slider, the detachable threaded slider is placed in the sliding way, the sliding way is fixedly connected with the tabletop support, the detachable threaded slider is connected with the lead screw in a sleeving manner and movesalong the axis direction of the lead screw, one end of the lead screw is connected with the driving device, the other end of the lead screw is connected with the tabletop support, and the driving device is mounted in the tabletop support. The overturning device is used for adjusting the tabletop overturning angle.

Description

technical field [0001] The invention belongs to the field of learning desk tabletop flipping, in particular to a hand-operated desktop flipping device. Background technique [0002] At present, on the children's study desks on the market, the desktop turning devices are mainly hydraulic devices or pneumatic devices. The adjustment angle is discontinuous. In the process, fingers may be pinched, which brings many unsafe factors to use. [0003] Therefore, there is an urgent need for a desktop turning device that is simple in operation, continuously adjustable in the turning angle of the desktop, and simultaneously ensures the safety of the user during use. Contents of the invention [0004] In order to solve the deficiencies in the prior art, the invention provides a desktop turning device with simple operation, continuous turning angle of the desktop, safe use and no pinching of fingers. [0005] The technical scheme that the present invention takes for solving the above-...
