Abstract

The invention relates to an extensible table which comprises a support, a bottom plate, a lead screw control motor, a main surface plate, a lead screw device and a movable surface plate, wherein the main surface plate is fixedly arranged on the bottom plate, and the movable surface plate is connected with the lead screw device. The lead screw device comprises a base, a connection guide rod, a bearing sleeve, a lead screw and a lead screw nut, wherein one end of the connection guide rod is movably connected with the base through a bolt, the other end of the connection guide rod is movably connected with the bearing sleeve through a bolt, and an isolation clamping block is arranged on the lead screw. The lead screw control motor is connected with the lead screw device and drives the lead screw to move horizontally in the axial direction of the bearing sleeve. A cam control motor is arranged on the bottom plate, an eccentric cam is arranged on a motor shaft of the cam control motor, and the motor shaft of the cam control motor is connected with the eccentric cam through interference fit. One end of the main surface plate is connected with the bottom plate through a hinge, and the bottom of the other end of the main surface plate is in contact with the upper end of the eccentric cam. The extensible table is simple in structure, high in transmission efficiency, free of slip and good in movement 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 through the following technical solutions: [0...
