Description

Technical Field

[0001] The utility model relates to the technical field of shells, in particular to a high-strength dustproof shell. Background Art

[0002] As we all know, a shell refers to a structure covering the surface of an object, usually used to protect the mechanical, electronic or other components inside the object. It can also provide isolation and connection between the external environment and the internal components. The shell can be designed into various shapes and materials according to different needs and uses, such as metal, plastic, glass, etc., to protect equipment, products or machinery from the external environment. It can also beautify the appearance, increase strength and improve safety. The shell is widely used in industry, electronics, automobiles, home appliances and other fields, playing an important role in protection, decoration and isolation.

At this time, the sealing push plate applies the force of the limit spring to compress it. When the sealing cover is placed, the limit spring releases the force to drive the sealing push plate to rebound, so that it can firmly limit the sealing cover. The dust, fine particles and debris in the air can be effectively filtered through the dustproof net to prevent them from entering the shell through the ventilation slot, and the dustproof net can be easily replaced or cleaned to prevent dust accumulation from clogging the dustproof net.
