[0019] Working principle:

[0020] First, since a lecture table body 2 is provided, the lecture table body 2 is composed of a top plate 21 and a bottom plate 22, and a lifting structure 3 is fixedly installed between the top plate 21 and the bottom plate 22. With the action of the lifting structure 3, the top plate 21 and the bottom plate 22 are lifted and lowered relative to each other. Among them, a threaded pin is fixedly installed at the center of the bottom surface of the lecture table board 1, and the threaded pin can detachably connect the lecture table board 1 and the top plate 21.

[0021] The lifting structure 3 is composed of a movable scissor brace 31, a rotating seat 32, a movable rotating shaft seat 33 and a lifting cylinder 34. One end of the movable scissor brace 31 is rotatably mounted on the rotating seat 32, and the other end of the movable scissor brace 31 is rotatably mounted on the movable rotating shaft seat 33. The lifting cylinder 34 is fixedly mounted on the top surface of the bottom plate 22, and the output end of the lifting cylinder 34 is fixedly connected to the movable scissor brace 31. With the power output of the lifting cylinder 34, the movable scissor brace 31 is extended and retracted in the vertical direction, thereby driving the top plate 21 and the bottom plate 22 to extend and retract in the vertical direction.

[0022] Among them, the movable shaft seat 33 is composed of a movable platform 331 and a movable pin 332. The movable platform 331 is fixedly installed on one end of the top surface of the base plate 22, and the movable pin 332 is sleeved on the movable platform 331. As the movable scissors support 31 rises and falls, the movable platform 331 can move in the horizontal direction to adapt to the deformation of the movable scissors support 31.

[0023] Among them, the bottom surface of the bottom plate 22 of the lecture table body 2 is fixedly installed with a caster 4, and the caster 4 is composed of a caster seat 41, a roller 42, a fixed support 43 and a top rotating handle 44. The caster seat 41 is fixedly installed on the bottom surface of the bottom plate 22, and the top rotating handle 44 is rotatably connected to the side wall surface of the caster seat 41, and the caster 4 is rotatably connected to the top rotating handle 44, and the bottom surface of the caster seat 41 is fixedly installed with a fixed support 43. When the top rotating handle 44 is parallel to the horizontal plane, the fixed support 43 stably supports the lecture table body 2 and the lecture table board 1 on the horizontal plane. When the top rotating handle 44 rotates, the caster 4 lifts up the entire lecture table body 2 and the lecture table board 1. As the caster 4 rotates, the entire lecture table can be driven to move in the horizontal direction.

[0024] The utility model provides a lecture table that is easy to move and transport. The lecture table board 1 and the lecture table body 2 are disassembled from each other, and the lecture table board 1 and the lecture table body 2 can be threadedly connected and disassembled. The lecture table body 2 is composed of a retractable structure, and the lecture table body 2 can be folded and lifted in the vertical direction. The bottom surface of the lecture table body 2 is fixedly installed with a movable caster 4, and the movable caster 4 can switch between a mobile mode and a stable mode, which is convenient for transportation and movement.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
