[0002] With the development of the times, environmental protection cabinets have become a kind of equipment that people often use at work. The general name of environmental protection cabinets is environmental protection gas insulated ring network cabinets. It is just a ring network cabinet that uses environmental protection gas as the insulating medium, aiming to reduce the impact on the environment. This type of ring network cabinet mainly uses dry air or SF6-free gas as the insulating medium, avoiding the greenhouse effect problem that may be caused by the use of SF6 gas, while ensuring the safety and reliability of the equipment. In the use of the environmental protection cabinet, an incoming line bushing is required, and the incoming and outgoing line bushing is a piping system used to manage wires, cables and other cables inside equipment, facilities or buildings. It is usually made of wear-resistant and high-temperature resistant materials, and is used to protect cables from damage, prevent accidental pulling, and has functions such as waterproof and dustproof. However, the existing incoming and outgoing line bushings for environmental protection cabinets still have certain defects; for example: the traditional incoming and outgoing line bushings for environmental protection cabinets have a single device structure and are not flexible to use. The incoming and outgoing line bushings of the equipment are S-shaped and cannot be replaced according to cables of different sizes during use. They cannot meet the use in various situations. The equipment is not equipped with a dustproof device. When the user uses it, dust from the outgoing line may enter the cable, resulting in poor contact, which can easily cause damage to the equipment, high maintenance frequency, and short equipment service life.
