Ultra-short-focus projector support

Abstract

The invention relates to the field of projectors, and particularly relates to an ultra-short-focus projector support which comprises a support base. An adjusting groove is formed in the bottom of the support base, an adjusting rod is slidably connected into the adjusting groove, the depth of the adjusting rod in the adjusting groove can be adjusted and locked, and the outer end of the adjusting rod is fixedly connected with a parallel plate perpendicular to the adjusting rod. The side, away from the adjusting rod, of the parallel plate is attached to the adjusting plate, magnetic strips which attract each other are arranged on the adjusting plate and the parallel plate, the side, away from the parallel plate, of the adjusting plate is fixedly connected with two positioning supporting rods, the other ends of the two positioning supporting rods are fixedly connected to a wall plate positioning block, and the wall plate positioning block is fixed to the lower portion of the projection wall surface. According to the invention, the projector can be rapidly adjusted to be parallel to a projection surface, hot air flow emitted by the projector and external air flow can be utilized to drive cooling oil to flow when the projector works so that the bottom plate can be rapidly cooled, the projector can move when being impacted, and the projector is prevented from being damaged in a fixed state.

Description

technical field [0001] The invention relates to the field of projectors, in particular to an ultra-short-focus projector bracket. 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. [0003] 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. [0004] With the improvement of people's living standards, projectors have replaced some TVs and become an important part of people's life and entertainment. In order to adapt to different usage environments, ultra-short-throw projectors have also emerged as the times require. [0005] However, when the ultra-short-throw projector is in use, because it is placed very close to the projection surface,...

AI Technical Summary

Problems solved by technology

[0005] However, when the ultra-short-throw projector is in use, because it is placed very close to the projection surface, and there is no fixed device on the table, a small movement will cause a large movement of the projection surface. The location is easy to be touched by people and damaged by force, and the projector will generate a lot of heat when it is in use, and the temperature of the desktop will rise when the heat is dissipated. It cannot dissipate heat well on the desktop. instrument and can avoid human touch damage as much as possible, and has a good heat dissipation performance bracket
