Novel support capable of being stably placed conveniently for teaching projector

Abstract

The invention discloses a novel support capable of being stably placed conveniently for a teaching projector. The novel support comprises a U-shaped supporting plate, a mounting sleeve pipe is fixedlyconnected to the middle of the lower end of the U-shaped supporting plate, the lower end of the mounting sleeve is fixedly connected to a supporting rod, the outer side of the supporting rod is movably sleeved with a fixing sleeve, an adjusting bolt is inserted at the upper end of the outer side of the fixing sleeve, and four inclined connecting rods are fixedly connected to the lower end of theouter side of the fixing sleeve; a fixing base is arranged below the fixing sleeve, a limiting sleeve ring fixedly sleeves the lower end of the inner side of a through hole in a guide rod, and a limiting circular plate is fixedly arranged at the upper end of the inner side of the through hole; the lower end of the guide rod is connected to a suction disc; and a pressure cylinder is fixedly installed in an installation round hole. According to the novel support, the novel support is more stably when being placed on the ground, the novel support is not prone to being knocked down when pedestrians are walking, so that the loss is avoided, meanwhile, the support is very convenient to move, and therefore the practicability is high, and popularization is facilitated.

Description

Technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a novel bracket for a teaching projector that is convenient for stable placement. Background technique [0002] Teaching projectors are also known as miniature projectors, teacher projectors, handheld projectors, TRT-3M portable projectors, mainly through 3M LCOS RGB three-color projectors and 720P film decoding technology, making traditional huge projectors compact and portable Modernization, miniaturization, entertainment, and practicability make the projection technology closer to life and entertainment. Teaching projectors are often bundled and installed on the bracket when used. However, most of the traditional projector brackets are placed on the ground and are very unstable. When passing by, it is easy to knock it down, causing the projector to be easily broken and cause losses. For this reason, we propose a new type of bracket for teaching projectors that is conven...

Problems solved by technology

[0002] Teaching projectors are also called micro projectors, teacher projectors, handheld projectors, TRT-3M portable projectors, mainly through 3M LCOS RGB three-color projection light machine and 720P chip decoding technology, the traditional large projectors are compact and portable Miniaturization, entertainment, and practicality make projection technology closer to life and entertainment. Teaching projectors are often bundled and installed on brackets when used. However, most of the traditional projector brackets are placed on the ground and are very unstable. When passing by, it is easy to knock it down, causing the projector to be easily broken and causing losses. Therefore, we propose a new type of bracket for teaching projectors that is easy to place stably
