Adjustable projection device for information technology research and using method

Abstract

The invention discloses an adjustable projection device for information technology research and a using method. The device comprises a projector body, wherein a flat plate is arranged on the top of the projector body, a long hole is formed in each of the front side and the rear side of the top of the flat plate, a fixing plate is fixedly connected to each of both sides of the top of the flat plate, a cross bar is fixedly connected to each of the front side and the rear side of the opposite sides of the fixing plate, the ends, away from the fixing plate, of the cross bars are fixedly connectedwith fixing blocks, the bottoms of the fixing blocks are fixedly connected with the top of the flat plate, and a spring sleeves the surface of each cross bar. The device has the advantages that the height and the rotation angle of a projector are convenient to adjust and the projector is convenient to dismount and maintain, and the problems that after existing projectors are fixedly mounted, the heights and the rotation angles of most existing projectors can not be adjusted so that the position of a projected image can not be adjusted, and the projector is not convenient to dismount and maintain after being damaged, and the trouble is brought to maintenance personnel are solved.

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...
