After the limiting component limits the self-opening component, the self-locking component can limit the limiting component, so that the limiting component is prevented from reducing the limitation of the self-opening component after long-time use, and the electricity utilization safety accident is caused;
The self-opening assembly, the limiting assembly and the self-locking assembly are matched with each other, so that the bus duct can be ensured to be in a closed state during working, and the bus duct can be rapidly opened when maintenance is needed, thereby facilitating maintenance of constructors.
As a further aspect of the present utility model, the self-opening assembly includes a first protrusion 101 mounted on the wire chase 1; the wire slot 1 is rotatably provided with a first connecting rod 3 and a second connecting rod 4, the first connecting rod 3 and the second connecting rod 4 are rotatably arranged on the cover plate 2, the first connecting rod 3 is provided with a second bulge 301, and a tension spring 5 is arranged between the first bulge 101 and the second bulge 301.
In this embodiment, the height of the first protrusion 101 is greater than the rotation centers of the first link 3 and the wire slot 1, the first link 3 and the tension spring 5 are located on different straight lines, so the tension spring 5 always gives tension to the first link 3 until the tension of the tension spring 5 is zero, the tension force drives the first link 3 to rotate, so as to drive the cover plate 2 to displace, so that the cover plate 2 is far away from the wire slot 1, and the first link 3 drives the second link 4 to rotate through the cover plate 2, so that the cover plate 2 always keeps parallel with the wire slot 1.
The self-opening assembly drives the cover plate 2 to move, so that the bus duct is in an opening state, and the cover plate 2 and the bus duct 1 can be closed only when pushing force (always larger than the pulling force of the tension spring 5) is applied to the cover plate 2.
