Demonstration device for visual communication major teaching

Abstract

The invention discloses a demonstration device for visual communication major teaching. The device comprises a base and a bearing plate, a vertical rod is mounted on the top surface of the base, a connecting plate is mounted at the bottom of the bearing plate, the top of the vertical rod is connected with the connecting plate through a rotating shaft, locking assemblies are installed on the outersides of the connecting plates, protective outer covers are installed on the two sides of the top face of the bearing plate correspondingly, guide grooves are formed in the inner sides of the protective outer covers correspondingly, lead screws are vertically installed on the surface of the bearing plate, pressing plates are installed on the outer sides of the lead screws through threads, and thepressing plates are located in the protective outer covers. Beneficial effects are that: the method is suitable for large-scale production, device with simple structure, the device is simple in structure and good in stability, the fixing pipe and the folding pipe can drive the spray head to reciprocate on the surface of the bearing plate, eraser crumbs are blown down, the device can be suitable for demonstration files of different widths by adjusting the angle between the folding pipe and the fixing pipe, meanwhile, the device can shoot and project manuscripts in real time in the teaching process, and teaching is facilitated.

Description

technical field [0001] The invention relates to the technical field of demonstration devices, in particular to a demonstration device for visual communication professional teaching.

In the process of using drawing paper, fixing the drawing paper is an indispensable mechanism, which is beneficial to prevent the drawing paper from sliding. Since the general working platform clamps the drawing paper with clips, it cannot effectively prevent the drawing paper from slipping. The paper slides, a little bit of sliding will lead to drawing errors, and when drawing needs to be modified, erasers will be used. The surface of these erasers is smooth glue, and they perform well in most occasions. but sometimes it also crumpled the paper

If you apply too much force, the eraser still has a chance to break the paper
