Mounting, hanging and fixing frame for projector in multimedia classroom

Abstract

The invention relates to a mounting, hanging and fixing frame for a projector in a multimedia classroom. The mounting, hanging and fixing frame comprises a base disc, a supporting mechanism and a clamping and adjusting mechanism; and the supporting mechanism is installed in the middle of the upper end face of the base disc, and the clamping and adjusting mechanism is installed at the upper end of the supporting mechanism in a running fit manner. The mounting, hanging and fixing frame can solve the problems that an existing projector fixing frame cannot adjust the height and the angle of the projector, so that the optical screen projection angle and height of the projector are difficult to adjust when the projector is used, the optimal projection effect of the projector cannot be achieved, and the teaching experience of teachers and the learning fun of students are affected; and the problems that the projector is easy to shake in use and the projection effect is affected due to the fact that the existing projector fixing frame cannot stably clamp and fix the projector, a reserved wire cannot be stored in the fixing frame, and winding is prone to happening when a connecting wire of the projector is too long can be solved.

Description

technical field [0001] The invention relates to the technical field of a projector fixing frame, in particular to a multimedia classroom projector installation suspension fixing frame. Background technique [0002] In this era of advanced information technology, multimedia classrooms have become an indispensable teaching tool. Multimedia classrooms are composed of multimedia computers, LCD projectors, digital video display stands, central control systems, projection screens, audio equipment and other modern teaching equipment. A projector, also known as a projector, is a device that can project images or videos onto a screen. It is also the most important and expensive device in the entire multimedia presentation classroom. It connects the computer system, all video output systems and digital The video display stand displays video and digital signal output on a large screen. The projectors used in multimedia classrooms are also called teaching projectors. The so-called tea...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the height and angle of the projector cannot be adjusted by the existing projector fixing frame, which leads to difficulty in adjusting the angle and height of the projector projected on the light screen during use, and the best projection effect of the projector cannot be achieved. It can also solve the problem of affecting the teacher's teaching experience and students' learning fun. It can also solve the problem that the existing projector fixing frame cannot stably clamp and fix the projector, which causes the projector to easily shake during use, which affects the projection effect and cannot be fixed. The reserved wire is stored in the rack, and the problem of winding is easy to occur when the projector wire is too long
