[0021] During use, through the interaction of the bus duct body 1, the strip top plate 2 and the protective mechanism 3, the bottom of the bus duct can be better protected during the hoisting process to avoid damage to the bus duct caused by impact, thereby ensuring the normal operation of the bus duct, thereby achieving better practicality, and through the interaction of the positioning slider 15 and the positioning slide groove 16, the positioning movable sleeve 12 can achieve better stability when moving, thereby ensuring that the protective mechanism 3 can work stably.

[0022] Working principle: When working, firstly rotate the fixing bolt 19 to fix the fixing mounting frame 18 on the top of the building indoors, so that the bus duct body 1 can be fixedly installed. Then, when it is hit during use, the impact object hits the strip protective bottom frame 4. Under the action of the positioning through hole 5, the strip protective bottom frame 4 moves upward on the outside of the positioning vertical rod 6. The strip protective bottom frame 4 moves upward to squeeze the first spring 10, so that the first spring 10 undergoes elastic deformation. At the same time, the strip protective bottom frame 4 pulls the wire rope 13, and the wire rope 13 drives the positioning movable sleeve 12 to slide downward on the outside of the positioning vertical rod 6. The positioning movable sleeve 12 drives the positioning slider 15 Sliding inside the positioning slide groove 16 can ensure that the positioning sleeve 12 can achieve better stability when moving. At the same time, the positioning sleeve 12 moves downward to squeeze the second spring 11, causing the second spring 11 to undergo elastic deformation. At the same time, the strip protective bottom frame 4 drives the protective rubber plate 17 to move upward. Through the movement of the above-mentioned structure, the kinetic energy generated by the impact can be damped and absorbed to prevent the impact from causing damage to the bus duct body 1. In this way, the bottom of the bus duct can be better protected during hoisting and use, avoiding damage to the bus duct caused by impact, ensuring the normal operation of the bus duct, and thus achieving better practicality.
