DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] In order to facilitate the fixing of the two steel shell cover plates 2 on the upper and lower sides of the bus duct body 1, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a bus duct body 1, and steel shell cover plates 2 are arranged on the upper and lower sides of the bus duct body 1. A fixing mechanism is arranged on the steel shell cover plate 2, and the fixing mechanism includes two positioning plates 3. A connecting rod 4 is formed between the two positioning plates 3 to fix the steel shell cover plate 2 to the upper and lower sides of the bus duct body 1. After the two positioning plates 3 are respectively arranged on the upper and lower sides of the bus duct body 1, the connecting rod 4 is inserted between the two positioning plates 3 through the through hole 7. When the connecting rod 4 is inserted, the handle 14 is pulled to slide the slider 11 along the length direction of the slide groove 10, driving the spring 12 to deform. Change, at this time, the limit block 9 follows the moving block 6 to move in the opposite direction of the slot 8, when the connecting rod 4 is inserted into the through hole 7, the handle 14 is released, and after the pressure is lost, the spring 12 is deformed again, and the elastic force is reacted to the slider 11, so that the moving block 6 moves toward the connecting rod 4. Finally, the limit block 9 is inserted into the limit groove 13 in the connecting rod 4 through the slot 8 to fix the connecting rod 4. Thus, the positioning area between the two positioning plates 3 is formed, and the two steel shell cover plates 2 can be firmly fixed to the upper and lower sides of the bus duct body 1, completing the installation of the steel shell cover plates 2. The overall structure is simple, and installation and disassembly are relatively convenient.

[0021] In order to facilitate the fixing of the connecting rod 4 between the two positioning plates 3, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a groove 5 is provided in the positioning plate 3, one end of the groove 5 is open, and a moving block 6 is provided in the groove 5. The moving block 6 extends to the outside of the positioning plate 3 through the open side of the groove 5. The movement of the moving block 6 can drive the limit plate to follow the movement. A through hole 7 is provided on the surface of the positioning plate 3. The through hole 7 passes through the positioning plate 3, and the through hole 7 is adapted to the connecting rod 4. The through hole 7 facilitates the installation and disassembly of the connecting rod 4 to complete the fixation of the two positioning plates 3. A slot 8 connected to the through hole 7 is provided in the groove 5, and a limiting block 9 is inserted in the slot 8. The limiting block 9 is connected to the moving block 6, and the limiting block 9 is driven to move by the moving block 6, so that the limiting block 9 can be inserted into the slot 8 and continue to move until it is inserted into the limiting groove 13 in the connecting rod 4. The groove 5 is also provided with a slide groove 10, and a slider 11 is movable along the length direction of the slide groove 10. The slider 11 is connected to the limit block 9. A spring 12 is connected to one end of the inner wall of the slide groove 10, and the other end of the spring 12 is connected to the slider 11. When the limit block 9 moves toward the side away from the slot 8, the slider 11 can pull the spring 12 to deform the spring 12. After the handle 14 is released, the spring 12 deforms and pulls the slider 11 to return the limit block 9 to its initial position and re-insert it into the limit groove 13. The two ends of the connecting rod 4 located in the through hole 7 are provided with limit grooves 13, and the limit grooves 13 are adapted to the limit block 9. The movable block 6 is extended to the end outside the positioning plate 3 and is connected to a handle 14.

[0022] A bus duct 16 includes the bus duct 16 steel shell cover 2 and the bus duct 16. Conductive copper sheets 15 are provided at both ends of the bus duct 16. The conductive copper sheets 15 are connected to external wires to complete the electrification of the bus duct 16.

[0023] When in use, first set the two positioning plates 3 on the upper and lower sides of the bus duct body 1 respectively, and then insert the connecting rod 4 between the two positioning plates 3 through the through hole 7. When the connecting rod 4 is inserted, pull the handle 14 to make the slider 11 slide along the length direction of the slide groove 10, driving the spring 12 to deform. At this time, the limit block 9 follows the moving block 6 to move in the opposite direction of the slot 8. When the connecting rod 4 is inserted into the through hole 7, release the handle 14. After the pressure is lost, the spring 12 deforms again and reacts the elastic force on the slider 11, so that the moving block 6 moves toward the connecting rod 4. Finally, the limit block 9 is inserted into the limit groove 13 in the connecting rod 4 through the slot 8 to fix the connecting rod 4. Thus, the positioning area between the two positioning plates 3 is formed, and the two steel shell cover plates 2 can be firmly fixed to the upper and lower sides of the bus duct body 1 to complete the installation of the steel shell cover plates 2.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
