[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Angle busbar trunking is a special type of busbar trunking used to achieve angled connections in a busbar system. It is commonly used in electrical shafts, especially in high-rise buildings, to connect busbar segments in different directions or at different angles, ensuring the continuity and stability of power supply.

[0004] Most common corner busbar trunking products currently use a fixed structure design, and their connection angle is not adjustable. This rigid structure has obvious limitations in actual installation: on the one hand, it is difficult to adapt to different on-site installation environments, and on the other hand, it also leads to increased installation difficulty and time consumption, thereby reducing the overall installation efficiency of the busbar trunking system. Therefore, an improvement is proposed. Utility Model Content

[0011] Further, the outer surfaces of the four slide rods are each slidably sleeved with a limiting plate fixedly connected between the limiting plate and the fixed sleeve, the limiting plate has a limiting effect on the slide rods, and can ensure the stability of the movement of the slide rods.

[0012] Further, the four movable pressing plates each include a sliding block fixedly connected with the slide rod, and the outer walls on both sides of the sliding block are slidably embedded with a back-shaped pressing plate, and the sliding block is arranged to facilitate the up-down movement of the back-shaped pressing plate.
