Abstract

The invention discloses an anti-blocking type projection system which includes a projector body and a projection curtain installed on a corresponding wall. Reflecting glass is arranged on a ceiling between the projector body and the projection curtain. The projector body is arranged on a fixing mechanism which comprises a bottom plate. A side plate is hinged with an upper end surface of the bottom plate. A transverse plate is hinged with an end portion of the side plate. The upper end surface of the bottom plate is provided with a first piston rod matched with the side plate, and a second piston rod matched with the transverse plate. The first piston rod and the second piston rod are arranged in a channel section arranged in the upper end surface of the bottom plate. A plurality of springs are arranged on two symmetrical side walls of the channel sections. Non-fixing ends of the springs are connected to clamping blocks. The springs on the two symmetrical side walls are arranged symmetrically. The anti-blocking type projection system solves the problems that existing fixing devices are not suitable for portable projectors and one part of the light emitted from the projectors is easily blocked by obstacles. Meanwhile, the height of the projector body can be adjusted.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to an anti-blocking projection system. Background technique [0002] Projectors are also known as projectors. At present, projection technology is changing with each passing day. With the development of science and technology, the projection industry has also developed into a field with the highest micro-projection technology. [0003] The projector is a precision electronic product, which integrates machinery, liquid crystal or DMD, and electronic circuits, so it must be carefully protected during use, especially to prevent it from being impacted. [0004] The projector needs to be fixed by a fixing device during use, which is not suitable for portable projectors. [0005] Moreover, in the existing projection system, part of the light emitted by the projector is easily blocked by obstacles, and a complete image cannot be seen. Contents of the invention [0006] The...
