[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Rectifier cabinets can be used in various industries, providing reliable DC power to ensure efficient and stable system operation. They offer stable DC power through precise current and voltage control. Traditionally, side panels are fixed to the rectifier cabinet with screws. When replacing or repairing the panel, the screw installation can lead to cumbersome disassembly, increasing maintenance complexity. To avoid this increased complexity during panel replacement or repair, rectifier cabinets can be designed to... Figure 1 - Figure 5 As shown, a rectifier cabinet is provided, which consists of a cabinet body 1, a side vertical plate 2 and a locking assembly 3, with the side vertical plate 2 located on one side of the cabinet body 1.

[0027] To facilitate quick disassembly and assembly of the rectifier cabinet's side panels and enhance the flexibility of disassembly and assembly, a locking assembly 3 is installed on the side vertical plate 2 to fix it to the cabinet body 1. The locking assembly 3 includes a limiting crossbar 31 located at both ends of one side of the side vertical plate 2, and a strip groove 32 opened inside the limiting crossbar 31. Limiting pins 33 are fixedly installed at both ends of the limiting crossbar 31. The limiting pins 33 penetrate the side vertical plate 2 and the side wall of the cabinet body 1 and extend to the inside of the cabinet body 1. Holes matching the limiting pins 33 are opened on both the side vertical plate 2 and the side wall of the cabinet body 1.

[0028] To enable quick disassembly and replacement of cabinet panels, saving time and effort, a clamping assembly 34 is provided on the limiting posts 33 to clamp them into the cabinet body 1. The clamping assembly 34 includes sliding grooves 341 respectively opened on the two limiting posts 33, a positioning groove 342 opened at one end of the limiting posts 33 and connected to the sliding grooves 341, and a movable push block 343 slidably disposed inside the sliding grooves 341. One end of the movable push block 343 passes through the limiting crossbar 31 and extends into the strip groove 32. Movable locking blocks 344 are slidably disposed on both sides of the interior of the positioning groove 342. The other end of the movable push block 343 has matching inclined surfaces on both sides and one side of the two movable locking blocks 344. A through groove 345 is provided, and a limiting spring 346 is provided inside the through groove 345, with its two ends fixed to two movable blocks 344 respectively. The two movable blocks 344 move to both sides and pull the limiting spring 346 respectively, causing the limiting spring 346 to be stretched elastically. A limiting vertical groove 347 is provided on one side of the positioning groove 342, which is opened inside the limiting pin 33. Limiting blocks 348 are slidably provided at both ends of the inner side of the limiting vertical groove 347. The two limiting blocks 348 are fixedly connected to the two movable blocks 344 respectively. The movable blocks 344 drive the limiting blocks 348 to slide inside the limiting vertical groove 347, thereby limiting the movable blocks 344 and making their movement more stable.

[0029] A movable component 35 for driving the clamping assembly 34 is provided on the limiting crossbar 31. The movable component 35 includes a movable connecting rod 351 slidably disposed inside the strip groove 32, with both ends of the movable connecting rod 351 fixedly connected to two movable push blocks 343 respectively, and a threaded hole 352 opened in the middle of the movable connecting rod 351. A spiral cap 353 is provided in the middle of one side of the limiting crossbar 31, and a threaded shaft 353 is fixedly disposed on one side of the spiral cap 353. The threaded shaft 353 passes through the limiting crossbar 31 and is rotatably connected to it through a bearing. One end of the threaded shaft 353 is threadedly connected to the threaded hole 352. When the threaded shaft 353 rotates, it drives the movable connecting rod 351 to slide inside the strip groove 32. The movable connecting rod 351 drives the movable push blocks 343 at both ends to move, thereby realizing the movement of the movable clamping block 344 to clamp the limiting clamping post 33 inside the cabinet 1.

[0030] In the actual installation process, the side vertical plate 2 is first placed on one side of the rectifier cabinet 1. Then, the limiting pins 33 at both ends of the limiting crossbar 31 are passed through the side vertical plate 2 and the side wall of the cabinet 1. Next, the spiral cap 353 is rotated, which drives the threaded shaft 353 on one side to rotate. While the threaded shaft 353 rotates, it drives the movable connecting rod 351 to slide inside the strip groove 32. The movable connecting rod 351 drives the movable push blocks 343 at both ends to move. The movable push blocks 343 push the two movable locking blocks 344 to move at the same time. The two movable locking blocks 344 move to both sides and contact the inner side wall of the cabinet 1, so that the limiting pins 33 are fixed on the cabinet 1, thereby fixing the limiting crossbar 31 and the side vertical plate 2 on the rectifier cabinet 1.
