Abstract

The invention relates to a projector with an anti-blocking function. The projector comprises a main body, a lens and four supporting blocks, and further comprises an anti-blocking mechanism and a protection mechanism, the anti-blocking mechanism comprises a heat dissipation assembly and two auxiliary assemblies, and the protection mechanism comprises a protection plate, a rotating shaft, a connecting block, a supporting rod, two second bearings and two connecting assemblies. Each connecting assembly comprises a power rod, a gear, a rack and two movable rods. According to the projector with the anti-blocking function, through the anti-blocking mechanism, the function of cleaning a filter screen is achieved, the probability of blockage of the filter screen is reduced, the influence on heat dissipation work is prevented, and the reliability of equipment is improved; and through the protection mechanism, the function of shielding a lens is achieved, the probability that the lens is scratched is reduced, and the projection effect is prevented from being influenced, so that the reliability of equipment is improved.

Description

technical field

[0001] The invention relates to the field of office equipment, in particular to a projector with an anti-blocking function. 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 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] The lens of the existing projector is usually exposed, which increases the chance of the lens being scratched, thus easily affecting the projection effect of the existing projector. Not only that, but the existing projector generally sets a filter screen to filter the inside of the main body. For heat dissipation work, after long-term heat dissipation, the filter screen is easily ...
