Combined display teaching aid for teaching

Abstract

The invention discloses a combined display teaching aid for teaching. The combined display teaching aid comprises a support base and a rotating base. The top end of the rotating base has a display stand. A combined display mechanism is arranged on a surface of the display stand. The combined display mechanism comprises a central seat disposed on the surface of the display stand. A plurality of inclined grooves are formed in a surface of the central seat. Inclined guide plates are arranged in the inclined grooves. One ends of the inclined guide plates are movably connected with the top end of the center seat, and the bottom surfaces of the other ends of the inclined guide plates are connected with a hinge seat, and the bottom end of the hinge seat is connected with a piston rod; the bottomend of the piston rod is connected with the surface of the display stand through the positioning seat; the top end of the center seat has a glass seat; a circuit positioning board is arranged on a surface of the glass seat; a plurality of positioning holes are formed in the surface of the circuit positioning board; the circuit positioning board on the glass seat can be used for installing and placing the electronic device, electrical experiment display is facilitated, and the entire glass seat is located at the top of the center seat. When the experiment is performed, a good demonstration effect can be obtained, and observation is facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a combined display teaching aid for teaching.

AI Technical Summary

Problems solved by technology

[0008] (1) General teaching aids can only be used for single-function writing and display, which cannot meet different teaching needs;

[0009] (2) At the same time, when using teaching aids, since most of them still use chalk to write, more dust will inevitably be produced when writing and wiping, which seriously affects the health of teachers;

[0010] (3) Moreover, the general teaching aids adopt a fixed structure when used, not only cannot be moved, but also cannot be adjusted. When performing a demonstration, there is a lack of intuitive contrast and a good demonstration effect cannot be achieved, and traditional teaching aids can only achieve Face-to-face demonstrations cannot be shared remotely, which greatly limits the use of teaching aids
