Abstract

The invention provides a teaching demonstration device, which comprises a storage frame, adjustable lifting frame structures, labor-saving moving frame structures, longitudinal limiting frames, a lifting display frame structure, a side edge positioning insertion pipe, a convex block, a movable cover plate, an inverted U-shaped frame, an automatic limiting frame structure, a storage frame, a display screen, a side edge insertion frame, a writing board, a rubber cushion block, a storage battery and a control button. The adjustable lifting frame structures are installed at the four corners of thelower portion of the storage frame; the labor-saving moving frame structures are mounted below the adjustable lifting frame structures; the longitudinal limiting frames are installed on the left sideand the right side of the inner wall of the storage frame through screws. Stretching air cylinders are inserted into the left side and the right side of the bottom of the storage frame, meanwhile, the upper portions of the stretching air cylinders are in bolted connection with a connecting plate, the stretching air cylinders can be conveniently used for driving the display frame to flexibly ascend and descend according to needs during use, and display objects in the display frame are conveniently displayed.

Description

technical field [0001] The invention belongs to the technical field of teaching auxiliary equipment, in particular to a teaching demonstration device. Background technique [0002] Now the general teaching demonstration device, including board body, frame, light strip group, jack, note block, locker and bracket, is relatively convenient to use. [0003] However, the existing teaching and demonstration devices do not have the flexibility to adjust the height of the displayed objects according to the needs, do not have the ability to adjust the height of the device according to the needs, and are inconvenient to move the device flexibly and fix the frame according to the needs. question. [0004] Therefore, it is very necessary to invent a kind of teaching demonstration device. Contents of the invention [0005] In order to solve the above technical problems, the present invention provides a teaching demonstration device to solve the problem that the existing teaching demo...
