For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] The embodiment of the present application discloses a power distribution cabinet. Referring to Figure 1 , Figure 2 and Figure 3 , the power distribution cabinet comprises a power distribution cabinet body 1, a U-shaped buckle 2 and a locking bolt 3, the power distribution cabinet body 1 is fixedly connected with a fixed block 4, the fixed block 4 is located at the back of the power distribution cabinet body 1, two fixed blocks 4 are arranged on the power distribution cabinet body 1 from top to bottom, a blind hole is formed in the U-shaped buckle 2 for the locking bolt 3 to pass through, a threaded hole is formed in the fixed block 4 for the locking bolt 3 to connect, and a locking assembly 5 is arranged on the fixed block 4 for locking the locking bolt 3.

[0022] When connecting, first, the U-shaped buckle 2 is environmentally friendly on the outside of the rod, then the U-shaped buckle 2 and the fixed block 4 are connected with each other through the locking bolt 3, finally, the rotation of the locking bolt is limited by using the locking assembly 5, the locking bolt 3 is limited by the mechanical mechanism, which ensures that it will not be affected by natural factors (natural wind), thereby achieving the effect of improving the problem that the bolts and nuts are loose due to the influence of outdoor factors on the cabinet on the rod, causing the power distribution cabinet to vibrate or fall off.

[0023] The locking assembly 5 includes a cover 51, a pull rod 52, a sliding plate 53, a spring 54 and a clamping block 55, the fixed block 4 is provided with a mounting groove, the mounting groove is provided with one at each end of the fixed block 4, the mounting groove is arranged along the direction parallel to the threaded hole, the cover 51 is connected to the fixed block 4, the cover 51 is located on the slot of the mounting groove, the pull rod 52 is arranged in the mounting groove through the cover 51, the cover 51 is provided with a through hole for the pull rod 52 to pass through, the axis of the pull rod 52 is arranged in line with the axis of the mounting groove, the sliding plate 53 is connected to the end of the pull rod 52 in the mounting groove, the side wall of the sliding plate 53 is slidably attached to the inner wall of the mounting groove, the spring 54 is sleeved on the rod of the pull rod 52 in the mounting groove, one end of the spring 54 abuts against the sliding plate 53, and the other end abuts against the cover 51, the clamping block 55 is connected to the end of the pull rod 52 not inserted into the mounting groove, and the clamping block 55 can be attached to the end of the locking bolt 3.

[0024] When connecting the U-shaped buckle 2, the clamping block 55 is pulled outward first, so that the clamping block 55 does not affect the subsequent connection of the locking bolt 3, then the locking bolt 3 is sequentially inserted through the U-shaped buckle 2 and the fixed block 4, the U-shaped buckle 2 is connected to the fixed block 4 by screwing the locking bolt 3, then the clamping block 55 is loosened, the sliding plate 53 is pushed by the spring 54 to move the clamping block 55 through the pull rod 52, so that the clamping block 55 is arranged outside the end of the locking bolt 3, since the clamping block 55 can only move horizontally, the rotation of the locking bolt 3 is limited.

[0025] The clamping block 55 is provided with a clamping groove, and part of the end of the locking bolt 3 can be clamped in the clamping groove, so that when the locking bolt is connected, the end of the locking bolt 3 is clamped into the clamping groove of the clamping block 55, and the contact area of the two is increased, which is conducive to improving the limiting effect of the clamping block 55 on the locking bolt 3.

[0026] The clamping block 55 is connected with a damping rotating shaft 6, the damping rotating shaft 6 is connected with a blocking rod 61, the blocking rod 61 is arranged in an "L" shape, the fixed block 4 is fixedly connected with a blocking block 41, and the blocking rod 61 can abut against the blocking block 41. When the clamping block 55 needs to be pulled outward, the blocking rod 61 is turned upward, and since the damping rotating shaft 6 has resistance, the position of the blocking rod 61 does not need to be manually maintained by the operator. After the clamping block 55 is moved into position, the blocking rod 61 can be reset to abut against the blocking block 41, so that the position of the clamping block 55 does not need to be manually maintained by the operator, which is conducive to the operation of the operator on the subsequent connection of the U-shaped buckle 2.

[0027] The fixing block 4 is provided with a groove adapted to the rod for connecting the power distribution cabinet body 1, so that the contact area between the fixing block 4 and the rod is increased, and the fixing effect between the two is improved.

[0028] The fixing block 4 is provided with an extrusion pad 42 located in the groove, which can increase the friction between the fixing block 4 and the rod, and further improve the fixing effect.

[0029] The fixing block 4 is provided with a slot for sliding insertion of the U-shaped buckle 2, so that the contact area between the fixing block 4 and the U-shaped buckle 2 is increased, and the fixing effect between the two is improved.

[0030] The implementation principle of the power distribution cabinet according to the embodiment is as follows: during connection, the U-shaped buckle 2 is first arranged on the outside of the rod, and then is inserted into the slot of the fixing block 4 in a sliding manner, then the stop rod 61 is rotated upward, and then the clamping block 55 is pulled outward to a position, and then the stop rod 61 is reset to abut against the stop block 41, the U-shaped buckle 2 and the fixing block 4 are connected to each other through the locking bolt 3, then the stop rod 61 is rotated upward to move away from the stop block 41, and finally the clamping block 55 is loosened, the sliding plate 53 is pushed by the spring 54 to drive the clamping block 55 to move through the pull rod 52, so that the clamping block 55 is clamped on the outside of the end of the locking bolt 3, since the clamping block 55 can only move horizontally, the rotation of the locking bolt 3 is limited through the mechanical mechanism, so that the locking bolt 3 is prevented from being affected by natural factors (natural wind), thereby the problem that the bolts and nuts are loosened due to the influence of outdoor factors on the rod cabinet, and the power distribution cabinet is vibrated or falls off is solved.

[0031] Finally, it should be noted that: the above description is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above embodiment, any technical solution falling within the idea of the present application belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application can also be considered as the protection scope of the present application.
