Dustproof assembly and projection equipment

Abstract

The embodiment of the invention provides a dustproof assembly and projection equipment. The dustproof assembly comprises a base, a dustproof net, a first support, a second support, a first magnetic attraction part and a second magnetic attraction part, wherein the dustproof net and the first support are arranged on the surface of the base in a stacked mode, the base is provided with a first sliding rail, a second sliding rail and a limiting structure, the first sliding rail and the second sliding rail are arranged oppositely, the limiting structure is located on one side of the first sliding rail and the second sliding rail, the second support is slidably connected to the first sliding rail and the second sliding rail, the second support is provided with a first end and a second end whichare opposite to each other, the first end is provided with a mounting groove, the first magnetic attraction part is accommodated in the mounting groove, the second magnetic attraction part is fixed tothe first support, and when the second support slides along the first sliding rail and the second sliding rail to enable the second end to abut against the limiting structure, the first magnetic attraction part is attracted to the second magnetic attraction part to enable the second support to cover the first support. According to the dustproof assembly provided by the embodiment of the invention, the second support can be conveniently taken down, and the maintenance and replacement are facilitated.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a dustproof component and projection equipment. Background technique [0002] In equipment with a large number of electronic components inside, such as computer chassis, equipment control cabinets, projection equipment, etc., generally, the chassis or housing of these equipment must be provided with ventilation to allow air to form convection inside the equipment. The mouth is used to dissipate heat from the electronic components built in the equipment, and when the air flows through the interior of the equipment, it will inevitably bring a lot of dust and waste in the air. Therefore, the equipment with a large number of electronic components inside Most of the air vents of the equipment are equipped with dust-proof nets. After the dust filter has been used for a long time, a large amount of dust will accumulate on its surface, which will block the vent to a certain...

AI Technical Summary

Problems solved by technology

After the dust filter has been used for a long time, a large amount of dust will accumulate on its surface, which will block the vents to a certain extent, resulting in a decrease in the air intake in the chassis or housing, which will affect the heat dissipation function and cause the device to overheat

However, the dust-proof nets of existing equipment with a large number of electronic components are usually not cleaned or replaced. Therefore, the dust-proof nets of these existing equipment are usually locked on the chassis of the equipment by screws. Or on the shell, special tools (such as screwdrivers, hexagonal wrenches, etc.) are required for disassembly, which is very inconvenient to disassemble.
