Problems solved by technology

[0003] When the ceiling is installed in the front projection mode, the projector and the boom are fixedly connected by screws, and the position, deflection angle, and inclination angle of the installed projector cannot be changed
Theoretically, the installed projector will accurately project the picture onto the projection screen, but in reality, the picture often has a certain offset, which is not conducive to viewing
Moreover, it is very inconvenient to disassemble and assemble the projector after being fixedly connected, the disassembly and assembly time is long, and the projector is easily damaged during disassembly and assembly.

Abstract

The invention relates to the field of projection equipment, in particular to a projector with the projection angle capable of being conveniently adjusted. According to the projector, the projection picture position can be freely adjusted, and positioning is accurate. In order to achieve the above technical aims, the projector with the projection angle capable of being conveniently adjusted comprises a machine body which is provided with a lens, a rotation holder is installed at the top of the machine body, a lifting rod is hinged to the rotation end of the rotation holder, and 1-4 stretchable support rods is/are further hinged to the top of the machine body; and a fixing sleeve is hinged to the other end of each support rod, and the fixing sleeves are connected to the lifting rod in a sleeving manner.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to a projector with convenient projection angle adjustment. 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. Projector installation methods are divided into desktop front projection, ceiling front projection, desktop rear projection, and ceiling rear projection. Front projection is where the projector and the audience are on one side; rear projection is where the projector and the audience are at both ends of the screen. For temporary use, you can choose the table ceiling method. If the ...
