Teaching projection equipment based on information technology

Abstract

The invention discloses teaching projection equipment based on information technology. The teaching projection equipment comprises a mounting seat and a containing box, a vertical rod is fixedly mounted in the middle of the lower end of the mounting seat, an outer pipe is rotatably mounted at the lower part of the outer surface of the vertical rod, a driving device is mounted on one side of the lower end of the mounting seat, a movable connecting mechanism is arranged between the outer pipe and the containing box, a mounting plate is fixedly mounted on the side, away from the movable connecting mechanism, of the lower portion of the outer surface of the outer pipe, a lifting mechanism is arranged between the mounting plate and the containing box, the containing box is of a cuboid structurewith the two sides and the front end being open and the interior being communicating, a projector is placed in the containing box, three fixing plates are fixedly connected to the outer surface of the mounting seat in an annular array mode, and two vertically-through screw holes are formed in the upper ends of each of three fixing plates. According to the teaching projection equipment based on the information technology, the projection angle can be conveniently adjusted at multiple angles, actual operation is easy and convenient, the automation degree is high, and the teaching projection equipment is suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the field of information technology equipment, in particular to a teaching projection device based on information technology. Background technique [0002] Information refers to the objects transmitted and processed by audio, news, and communication systems. It generally refers to all the content of human society. Human beings can distinguish different things by obtaining and identifying different information from nature and society, and can understand and transform the world. In all communication and In the control system, information is a form of universal connection. The society is accustomed to linking science and technology together, collectively referred to as science and technology, referred to as science and technology. In fact, the two are closely related and have important differences. Scientifically solve theoretical problems. , technology solves practical problems, and the problem that science needs to solve is to d...

Problems solved by technology

[0003] With the continuous development and progress of society, information technology teaching is gradually developed, and projection equipment is needed in information technology teaching. Most of the existing projection equipment is used in conjunction with projectors and screens to achieve the purpose of projection. Now In the prior art, most projectors are fixed on the desktop or fixedly installed on the ceiling. Placing the projector on the desktop can facilitate the adjustment of its position and height, but it also makes the projector occupy a certain amount of space. In the desktop space, the space utilization rate is low, and the projector is directly fixed and installed on the indoor ceiling through bolts, and its projection angle is difficult to adjust. Therefore, the inventor has proposed a teaching projection device based on information technology after long-term research.
