Cabinets are generally equipped with doors, removable or non-removable side panels and back panels. Cabinets are an indispensable component of electrical equipment and are the carrier of electrical control equipment. They are generally made of cold-rolled steel plates or alloys. They can provide waterproof, dustproof, and anti-electromagnetic interference protection for stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

[0003] When opening an existing cabinet, an ordinary cabinet needs to use tools to open a part of the cabinet in order to observe and repair the internal parts. Due to the obstruction of the cover, it is often difficult to install. In the subsequent use process, dust adheres to the inside of the cabinet, causing creepage in the equipment, and the air outlet is very likely to cause gas backflow, aggravating the accumulation of dust.
