[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0023] Referring to Figure 1-7 As shown, a power distribution cabinet convenient for internal maintenance includes a cabinet body 1. A cabinet door 2 is rotatably installed at the front end of the cabinet body 1. A handle 3 is fixedly installed on the right side of the front end of the cabinet door 2. Heat dissipation ports 4 are respectively formed through the left and right ends of the cabinet body 1. The heat dissipation ports 4 help to dissipate the heat generated inside the cabinet body 1 to the external environment by allowing the surrounding air to circulate. Dust-proof nets 5 are respectively arranged inside the two heat dissipation ports 4. The dust-proof nets 5 can effectively block dust, hair, fibers and other small particles in the air from entering the inside of the cabinet body 1, avoiding the accumulation of dust on the surfaces of electrical components. A first sliding groove 6 is formed at the inner bottom plate of the cabinet body 1. A threaded rod 7 is rotatably installed inside the first sliding groove 6. The rear end of the threaded rod 7 is fixedly connected to a first rotating rod 14. The other end of the first rotating rod 14 extends into the inside of the activity groove 13 and is fixedly installed with a first bevel gear 15. An activity groove 13 is formed at the inner rear side wall of the cabinet body 1. A second rotating rod 16 is rotatably installed inside the activity groove 13. A second bevel gear 17 is arranged on the outer surface of the second rotating rod 16. The second bevel gear 17 meshes with the first bevel gear 15. By using the second bevel gear 17 and the first bevel gear 15, the threaded rod 7 can be driven to rotate by rotating the rotating disc 18, and then the moving block 8 on the surface of the threaded rod 7 can be adjusted, so that the moving plate 9 at the upper end of the moving block 8 moves forward. The left end of the second rotating rod 16 extends out of the left side wall of the activity groove 13 and is fixedly connected to a rotating disc 18.

[0024] Referring to Figure 2 、 Figure 6 and Figure 7As shown in the figure, third sliding grooves 19 are provided on both the left and right sides of the upper side wall inside the cabinet body 1, and second sliding grooves 11 are provided on both the left and right sides of the bottom end inside the cabinet body 1. The second sliding grooves 11 are located on the left and right sides of the first sliding groove 6. A moving block 8 is threadedly connected to the outer surface of the threaded rod 7. The upper end of the moving block 8 is fixedly connected to a moving plate 9. Sliders 92 are fixedly installed on both the left and right sides of the upper end of the moving plate 9. The sliders 92 are slidably connected to the inside of the third sliding groove 19. Pulley 12 are provided on both the left and right sides of the lower end of the moving plate 9. The sliders 92 and the pulley 12 can provide a stable supporting force for the movement of the moving plate 9. The pulley 12 slides inside the second sliding groove 11. Two slots 91 are provided on the left side of the front end of the moving plate 9. An installation plate 10 is rotatably installed at the front end of the moving plate 9. A plug 101 adapted to the slot 91 is fixedly installed on the left side of the rear end of the installation plate 10. A pull ring 102 is fixedly installed on the left side of the upper end of the installation plate 10. When it is necessary to rotate the installation plate 10, the plug 101 is removed from the inside of the slot 91 through the pull ring 102, and the installation plate 10 can be adjusted, making it more convenient for the maintenance master during the maintenance process. A first lighting lamp 20 and a second lighting lamp 21 are fixedly installed on the upper side wall inside the cabinet body 1. The second lighting lamp 21 is located on the right side of the first lighting lamp 20. The first lighting lamp 20 is used to illuminate when the installation plate 10 is moved to the cabinet door 2, and the second lighting lamp 21 is used to illuminate the rotated installation plate 10.

[0025] The working principle and usage process of the present utility model: When it is necessary to repair the power distribution cabinet, the cabinet door 2 is opened through the handle 3, and the rotating disc 18 is rotated. The rotation of the rotating disc 18 drives the second rotating rod 16 to rotate. The rotation of the second rotating rod 16 drives the second bevel gear 17 to rotate. The second bevel gear 17 meshes with the first bevel gear 15. Therefore, the first rotating rod 14 connected to the first bevel gear 15 rotates. The first rotating rod 14 drives the threaded rod 7 to rotate. The rotation of the first threaded rod 7 drives the moving block 8 to move forward inside the first sliding groove 6. The moving block 8 drives the moving plate 9 at the upper end to move forward. The moving plate 9 drives the installation plate 10 at the front end to move forward until it reaches the front end of the cabinet body 1. When the environment is dim, the first lighting lamp 20 provides light. According to the needs of the repair, the plug 101 at the rear end of the installation plate 10 is pulled out from the slot 91 at the front end of the moving plate 9 through the pull ring 102, so that the installation plate 10 is perpendicular to the moving plate 9. When the environment is dim, the second lighting lamp 21 provides light, which is convenient for the repair and maintenance of electrical components and provides convenience for the maintenance work of maintenance personnel.
