An adjustable projection device for information technology research and its usage method

Abstract

The invention discloses an adjustable projection device for information technology research and a use method thereof, comprising a projector body, a flat plate is placed on the top of the projector body, and long holes are opened on the front side and the rear side of the top of the flat plate , both sides of the top of the flat plate are fixedly connected with a fixed plate, the front side and the rear side of the opposite side of the fixed plate are fixedly connected with a cross bar, and the end of the cross bar away from the fixed plate is fixedly connected with a fixed block, The bottom of the fixed block is fixedly connected with the top of the flat plate, and the surface of the cross bar is covered with a spring. The present invention has the advantages of being convenient for adjusting the height and rotation angle of the projector, and facilitating disassembly and maintenance of the projector, and solves the problem of existing problems. After some projectors are fixed and installed, most of them cannot adjust the height and rotation angle, so that the position of the projected image cannot be adjusted. When the projector is damaged, it is not convenient to disassemble and repair the projector, which brings troubles to the maintenance personnel.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to an adjustable projection equipment for information technology research and a usage method. 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. Instruments are currently 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] Most existing projectors cannot adjust the height and rotation angle after being fixedly installed, so that the position of the projected image cannot be adjusted. When the projector is damaged, it is inconvenient to disassemble and repair the projector, which brings trouble to the maintenance personnel. Contents of th...
