[0028] The connecting assembly 13 includes a fixing box 14, a slide rod 15, a spring 16, a first Z-shaped toothed plate 17, a second Z-shaped toothed plate 18, a connecting rod 19, a gear 20, a hexagonal block 21, and a positioning post 24. The inner surface of the fixing box 14 is fixedly connected to the slide rod 15. One end of the spring 16 is fixedly connected to the first Z-shaped toothed plate 17, and the other end of the spring 16 is fixedly connected to the second Z-shaped toothed plate 18. The outer surface of the connecting rod 19 is fixedly connected to the gear 20, and the outer surface of the connecting rod 19 is fixedly connected to the hexagonal block 21. The upper surface of the fixing box 14 is fixedly connected to the positioning post 24. The inner surface of the insertion hole 22 is adapted to the first Z-shaped toothed plate 17, and the inner surface of the insertion hole 22 is adapted to the first Z-shaped toothed plate 17. The two Z-shaped toothed plates 18 are adapted to each other, the inner surface of the slot 23 is adapted to the first Z-shaped toothed plate 17, the inner surface of the slot 23 is adapted to the second Z-shaped toothed plate 18, the inner surface of the positioning slot 25 is adapted to the positioning post 24, there are two connecting components 13 and they are distributed on the left and right, the side surface of the housing 1 is fixedly connected to the fixed box 14, the spring 16 is slidably sleeved on the outer surface of the slide rod 15, the outer surface of the slide rod 15 is slidably connected to the first Z-shaped toothed plate 17, the outer surface of the slide rod 15 is slidably connected to the second Z-shaped toothed plate 18, the gear 20 is meshed with the first Z-shaped toothed plate 17, the gear 20 is meshed with the second Z-shaped toothed plate 18, and the outer surface of the connecting rod 19 is rotatably connected to the fixed box 14.

[0029] Working principle: When maintenance and repair of the frequency converter module inside the housing 1 are required, simply rotate the hexagonal block 21 on the connecting assembly 13 to drive the connecting rod 19 to rotate the gear 20. Under the meshing action of the gear 20 with the first Z-shaped toothed plate 17 and the second Z-shaped toothed plate 18, the first Z-shaped toothed plate 17 and the second Z-shaped toothed plate 18 are driven to move towards each other along the slide rod 15, compressing the spring 16. This causes the first Z-shaped toothed plate 17 and the second Z-shaped toothed plate 18 to disengage from the slot 23. Then, the cover plate 2 can be pulled upwards along the insertion hole 22 to complete the disassembly of the cover plate 2. After maintenance and repair, simply align the positioning groove 25 on the cover plate 2 with the positioning post 24 on the connecting assembly 13 and insert it to quickly complete the installation and positioning of the cover plate 2. Then, fully insert the insertion hole 22 into the first Z-shaped toothed plate in the opposite moving state. When the first Z-shaped toothed plate 17 and the second Z-shaped toothed plate 18 correspond to the slot 23, the hexagonal block 21 is released. Under the action of the spring 16, the first Z-shaped toothed plate 17 and the second Z-shaped toothed plate 18 will automatically insert into the slot 23, completing the limiting installation of the cover plate 2. This is simple and convenient. When the entire heat dissipation assembly needs to be replaced, simply pull the limiting plate 5 upwards to disengage the female magnet ring 4 from the female strong magnet ring 3, thereby releasing the magnetic attraction restriction between the heat dissipation assembly and the cover plate 2. Then, insert the sleeve 6 on the new heat dissipation assembly into the through hole 26 and make the female strong magnet ring 3 and the limiting plate 5 strongly magnetically connected to each other, thus completing the installation of the new heat dissipation assembly. This is simple and convenient. Moreover, under the action of the first dustproof net 7, external dust can be prevented from entering the interior of the housing 1, thereby improving the service life of the frequency converter module.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
