[0024] like Figure 1-4 As shown, the utility model provides a busbar duct cover plate that is easy to disassemble and assemble, including a cover plate body 1, a covering side plate 2 arranged on both sides of the bottom of the cover plate body 1, and a connecting groove seat 5 for inserting the covering side plate 2, the inside of the covering side plate 2 is hollow, and the inside of the covering side plate 2 is provided with an elastic ejection component 3 for ejecting the protrusion 4 inside the covering side plate 2 outward, and the connecting groove seat 5 is installed on both sides of the busbar duct, and a through groove A6 is provided thereon, that is, the connecting groove seat 5 is fixed in advance at the appropriate positions on both sides of the busbar duct, so that the cover plate can be closely attached. When the surface of the bus duct is open, the sheathing side plate 2 is just inserted into the connecting groove seat 5 (the protrusion 4 is pressed into the sheathing side plate 2 during insertion). After the sheathing side plate 2 is inserted into the connecting groove seat 5, the protrusion 4 also passes through the through groove A6 in the elastic ejection component 3, thereby fixing the connecting groove seat 5 and the sheathing side plate 2, and the installation of the sheathing side plate 2 is completed. The protrusion 4 is pressed into the sheathing side plate 2 again, and the sheathing side plate 2 can be pulled out from the connecting groove seat 5 to complete the disassembly of the cover plate body 1. The disassembly and assembly is very convenient and does not require tools.

[0025] Furthermore, the surface of the cover body 1 is concave-convex, so that the groove-shaped structure of the surface of the cover body 1 can reduce the cross-sectional area of ​​the object and increase the bending rigidity of the object, thereby improving the strength and stability of the cover body 1. This is because the groove can disperse the stress and concentrate the stress on the edge of the groove, thereby reducing the overall stress concentration effect. At the same time, a heat dissipation groove 8 is opened on the top of the cover body 1, and a dustproof net 9 is installed on the inner side wall of the heat dissipation groove 8. The dustproof net 9 can effectively block most dust particles and allow air circulation to achieve the purpose of heat dissipation.

[0026] The elastic ejection component 3 includes a rectangular rod 301 fixed on both sides of the inner side of the coated side plate 2, and a movable plate 302 is movably connected to the inner side of the coated side plate 2. A through groove B303 that can pass through the rectangular rod 301 is opened on both sides of the inner side of the movable plate 302, and a groove 304 is opened on the back of the movable plate 302. A spring 305 is installed between the inner surface of the groove 304 and the inner bottom wall of the coated side plate 2. The surface of the movable plate 302 is fixed to the protrusion 4. When the protrusion 4 is pressed into the movable plate 302, the movable plate 302 moves toward the inner bottom wall of the coated side plate 2, and the through groove B303 thereon will slide along the rectangular rod 301. It should be noted that the cross section of the through groove B303 is consistent with the cross section of the rectangular rod 301. The cross sections are the same, so that the movable plate 302 can only move in a straight line along the rectangular rod 301, while squeezing the spring 305. After the coated side plate 2 is fully inserted into the connecting groove seat 5, the protrusion 4 is aligned with the through groove B303. The protrusion 4 is no longer blocked, and the spring 305 uses its elasticity to push the protrusion 4 out again, thereby passing through the through groove B303 to fix the connecting groove seat 5 and the coated side plate 2. The spring 305 is arranged in the groove 304. The spring 305 is squeezed the most when the back of the movable plate 302 is close to the inner bottom wall of the coated side plate 2. At this time, there is still enough space in the groove 304 to accommodate the spring 305, so as to avoid excessive deformation and damage of the spring 305.

[0027] In addition, a reinforcement component 7 is installed between the protrusion 4 and the connecting groove seat 5. The reinforcement component 7 includes a connecting plate 701 including the four corners of the side plate. The surface of the connecting plate 701 is connected to the square block 703 through a telescopic rod 702. Square grooves 704 for inserting the square block 703 are provided on both sides of the protrusion 4. An iron block is fixedly connected to the surface of the square block 703. An iron magnet is bonded to the inner surface of the square groove 704. A handle 705 is fixedly connected to the surface of the square block 703 near the telescopic rod 702. That is, when the protrusion 4 passes through the through groove B303, the square groove 704 on the protrusion 4 It is just aligned with the square block 703, and the other parts of the square block 703 except the connection with the handle 705 are inserted into the square groove 704 through the handle 705 on the square block 703. The telescopic rod 702 is extended to assist the movement of the square block 703, so that the square block 703 is inserted into the square groove 704. After the insertion is completed, the iron block on the square block 703 is just close to the magnetic block inside the square groove 704. The contact between the two will generate a certain gravitational force, thereby better limiting the position of the protrusion 4, so as to reinforce the connection between the connecting groove seat 5 and the covering side plate 2, and finally reinforce the installation of the cover plate body 1.

[0028] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
