A cad simulation teaching demonstration projection device

Abstract

The invention discloses CAD simulation teaching demonstration projection equipment. The CAD simulation teaching demonstration projection equipment comprises a mounting frame, a supporting plate, sliding plates, a bottom connecting frame, a lifting plate, a placement table, a charging barrel and a projector, wherein the supporting plate is arranged in the middle of the mounting frame, the sliding plates are symmetrically arranged at the two ends of the supporting plate, the bottom connecting frame is arranged at the bottom of the mounting frame, the bottom connection frame is of a rectangular structure, and the placement table is horizontally arranged at the top of the mounting frame. The CAD simulation teaching demonstration projection equipment has the beneficial effects that a second hydraulic pump drives the projector to move up and down through a hydraulic column, so that the range of the projector capable of adjusting and moving up and down is higher and larger, and the teachers can conveniently conduct CAD simulation teaching demonstration on students in different areas and places; the fan penetrates through a side dust suction plate and a suction edge plate to suck the flying dust into a dust collection bin, the projection image of the projector is guaranteed to be more clearly visible, the quality of projection and CAD simulation demonstration is improved, and the neatness of the use of the projector on the equipment is ensured.

Description

technical field [0001] The invention relates to a projection device, in particular to a CAD simulation teaching demonstration projection device, and belongs to the technical field of projection device applications. Background technique [0002] With the rapid development of people's living standards, projection equipment is used more and more frequently in cad simulation teaching and demonstration work. The projection equipment projects the demonstration screen onto the wall screen through the projector, which improves the efficiency and efficiency of students' cad simulation learning. quality. [0003] There are still many deficiencies in the existing projection equipment used for cad simulation teaching demonstration in use. When the existing cad simulation teaching demonstration projection equipment is projecting, the position, height, direction and angle of the projection are fixed and cannot be adjusted. When teachers are performing projection demonstrations, they cann...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the projection position, height, direction and angle of the existing cad simulation teaching demonstration projection equipment are fixed and cannot be adjusted. When the teacher is performing projection demonstration, the projection cannot be adjusted according to different venues The height, direction and angle of the projection position of the equipment are flexible and poor in diversity. When the projection equipment is projecting, the lens of the projector is prone to dust, which affects the projection clarity of the projector, and the projected picture is blurred. Clear, and the cleanliness of the projection equipment is plugged in, the projection equipment is not easy to move, and the projection equipment is not stable enough when it is working, and the parts of the projection equipment are not easy to install and disassemble. A cad simulation teaching demonstration projection equipment is proposed
