Teaching projector support with high applicability

Abstract

The high-applicability teaching projector support comprises a base, a supporting rod is fixedly connected to the top of the base, a lifting column is vertically arranged in an inner cavity of the supporting rod, a left annular plate is fixedly connected to the top of the left side of the inner cavity of the supporting rod, and a threaded rod is arranged at the top of the right side of the supporting rod in a penetrating mode. According to the invention, the base, the supporting rod, the lifting column, the rotating box, the mounting plate, the projector body, a left annular plate, a driving rotating rod, a gear, a through groove, a cooling fan, a driven rotating rod, a threaded rod, a threaded groove, a right annular plate, a spring, a transverse plate, a through hole, a temperature sensor, a limiting rod, a pull rod, a mounting groove and a connecting plate are cooperatively used; the problems that an existing projector support does not have the height adjusting function, the angle adjusting function, the convenient dismounting function and the projector heat dissipation function, various requirements of a user cannot be met in the use process of the support, and the practicability of the projector support is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a teaching projector bracket with strong applicability. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] During the use of teaching projectors, projector brackets are often used to place teaching projectors. The existing projector brackets do not have the functions of height adjustment, angle adjustment, easy disassembly and heat dissipation of the projector. During the use of the bracket, various needs of users cannot be met, which reduces the practicability of the projector b...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a teaching projector bracket with strong applicability, which has the advantages of height adjustment, angle adjustment, easy disassembly and heat dissipation of the projector, and solves the problem that the existing projector bracket does not have the advantages of height adjustment and angle adjustment. , The function of easy disassembly and heat dissipation of the projector cannot meet the various needs of users during the use of the bracket, which reduces the practicality of the projector bracket
