Abstract

The invention relates to an extendable desk, comprising a bracket, a bottom plate, a screw control motor, a main panel fixedly installed on the bottom plate, a screw device, and a movable panel connected with the screw device, and the screw device includes a base, Connect the guide rod, the bearing sleeve, the screw rod and the screw nut. One end of the connecting guide rod is connected to the base by bolts, and the other end of the connecting guide rod is connected to the bearing sleeve by bolts. The screw rod A blocking block is arranged on the top, the screw control motor is connected with the screw device, and the screw control motor drives the screw to move horizontally along the axial direction of the bearing sleeve; a cam control motor is set on the bottom plate, and the cam control motor An eccentric cam is arranged on the motor shaft of the cam control motor, and the motor shaft of the cam control motor is connected with the eccentric cam through an interference fit. One end of the main panel is connected with the bottom plate through a hinge, and the bottom of the other end is in contact with the upper end of the eccentric cam. The invention has a simple structure , High transmission efficiency, no slipping phenomenon, good motion performance.

Description

technical field [0001] The invention relates to an extendable desk. Background technique [0002] Because the horizontal class tabletop is more likely to cause the fatigue of the user's lumbar spine than the inclined class tabletop, it is easy to cause many health problems such as back pain, hunchback and myopia for students after a long time. Therefore, by changing the angle of the desktop to effectively improve the comfort of writing, the above problems can be reduced. Because the drawing table is different from ordinary desks, it is very inconvenient to go to a special drawing classroom every time you draw. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides an extendable desk with simple structure, high transmission efficiency, no slipping phenomenon and good motion performance. [0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions: an extenda...
