[0002] Bus duct is usually used for centralized power supply and distribution of power system. Its main function is to introduce high-voltage power supply into various distribution equipment through conductive busbars to ensure the normal operation of power supply system. There are multiple parallel conductive busbars inside the bus duct. These busbars are used to transmit electric energy and can be installed inside or outside the building to supply power to electrical equipment such as lighting, air conditioning, motors, etc. Bus ducts are gradually leaning towards lightweight and energy-saving development to ensure production and use needs. The existing patent (Announcement No.: CN216904205U) is a new type of lightweight bus duct. The bus duct can adjust the height and position of the whole bus duct through a height-adjustable bracket mechanism, which is convenient for connecting two sections of bus duct during installation, reducing the difficulty of installation and improving construction efficiency. Through the cooperation between the sealing strip and the sealing groove, it can play a good waterproof and dustproof role, preventing water and dust from penetrating into the inner side of the upper cover and the lower cover, causing circuit failure. However, the trough body and the cover plate of the bus duct are connected by bolts, and tools need to be used for fixing during installation, which is very inconvenient to use and reduces the installation efficiency.
