[0002] Electrical equipment refers to the general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. They are mainly used for power generation, transformation, transmission, distribution or utilization of electrical energy. Electrical equipment consists of two parts: power supply and power-consuming equipment. The power supply includes batteries, generators and their regulators. The power-consuming equipment includes the engine's starting system and the car's lighting, signals, instruments, etc. In the forced ignition engine, it also includes the engine's ignition system. Common electrical equipment includes transformers, high-voltage switchgear, low-voltage cables, electric meters, electronic devices, etc. Electrical equipment plays an important role in production and life, enabling the normal operation and transmission of electricity, and providing convenience for people's life and work. Sheet metal chassis refers to the use of comprehensive processing technology to form the required chassis. The processing technology includes shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent, and it is often used to place various electrical equipment.

[0003] Existing electrical equipment usually has a chassis, and multiple devices are arranged in the chassis. In order to prevent accidental contact, misoperation and dust, a cover is usually fixed on the window of the chassis by screws. When operation is required, the screws and the cover are removed by tools. After the operation, the cover is fixed to the chassis by the tool through the screws. This operation method requires the use of tools, resulting in low operational convenience, and the cover and screws are easy to lose after being removed. Heat dissipation is performed by setting heat dissipation ports on the chassis. A filter needs to be set on the heat dissipation port to prevent impurities from entering the sheet metal chassis. The filter on the sheet metal chassis is fixed to the chassis, and it is troublesome to remove the filter for cleaning or replacement. Utility Model Content
