Two fixing plates 5 are fixedly connected to the bottom of the rotating plate 3, and a rotating plate 6 is rotatably connected to the bottom of the fixing plates 5. A rotating shaft is rotatably connected to the bottom of the rotating plate 6, and a rotating plate 8 is rotatably connected to the outside of the rotating shaft. The bottom of the rotating plate 8 is rotatably connected... A movable plate 9 is connected to the front of the movable plate 9, a push plate 10 is fixedly connected to the front of the push plate 10, a movable rod 11 is fixedly connected to the front of the movable rod 11, and a movable block 12 is fixedly connected to the front of the movable rod 11. The fixed plate 5 is fixed to the groove plate 13 of the rotating plate 3 and receives the rotational force of the movable plate 8. The movable plate 9 moves, thereby driving the rotating plate 8 to rotate. The push plate 10 drives the movable plate 9 to move. The movable block 12 drives the movable rod 11 to move. The movable block 12 receives external force and thus slides. A disassembly assembly for quick disassembly of the busbar is fixedly connected to the bottom of the base plate 1.

[0033] Reference Figure 2 and Figure 4The disassembly assembly includes a fixing block 14, the top of which is fixedly connected to the bottom of the base plate 1. The fixing block 14 moves with the base plate 1 and also limits its movement. A force-applying block 15 is fixedly connected to the bottom of the fixing block 14. The force-applying plate 4 receives the pushing force of the fixing block 14, thereby moving. A connecting shell 25 is fixedly connected to the bottom of the base plate 1. The connecting shell 25 is a device for fixing the busbar. Two inclined plates 16 are slidably connected to the inner wall of the connecting shell 25. The inclined plates 16 receive the pushing force of the force-applying plate 4. For movement, a second moving rod 17 is fixedly connected to the left side of the inclined plate 16. The second moving rod 17 moves with the inclined plate 16. A second fixing plate 18 is fixedly connected to the inner wall of the connecting shell 25. A motor 19 is fixedly connected to the left side of the second fixing plate 18. A rotating rod is fixedly connected to the drive end of the motor 19. A fourth rotating plate 21 is fixedly connected to the right side of the rotating rod. The second fixing plate 18 fixes the motor 19, ensuring its stable operation. The rotating rod receives the rotational force from the motor 19, thereby driving the fourth rotating plate 21 to rotate.

[0034] Reference Figures 1 to 3 A force-applying plate 4 is fixedly connected to the bottom of the rotating plate 3. The force-applying plate 4 directly contacts the busbar, thereby fixing the busbar. A placement groove is fixedly connected to the left side of the rotating shaft. The placement groove is used to place the busbar. The external sliding connection of the moving rod 11 is to the rear interior of the outer casing 2. The moving rod receives the thrust of the moving block 12, thereby moving. A grooved plate 13 is fixedly connected to the top of the bottom plate 1. The bottom of the moving block 12 is slidably connected to the top of the grooved plate 13. The grooved plate 13 allows the moving block 12 to move on it, thereby moving stably. A moving plate 26 is slidably connected to the top of the moving block 12. A partition 27 is fixedly connected to the inner wall of the moving block 12. Springs 20 are fixedly connected to both sides of the partition 27. Limit blocks 7 are fixedly connected to the opposite side of the two springs 20. The moving plate 26 moves within the moving block 12, thereby moving the limit blocks 7, thus... Spring 1 20 receives the pushing force of limiting block 7, thereby compressing. Partition 27 separates the two springs 1 20 and limiting block 7. Moving rod 2 22 is fixedly connected to the left side of moving rod 2 17. Moving rod 3 22 receives the pushing force of moving rod 2 17, thereby moving. Limiting plate 24 is fixedly connected to the bottom of connecting shell 25.

Limiting plate 24 is fixed inside connecting shell 25, thereby compressing spring 2 23. The bottom of rotating plate 4 21 contacts the top of moving rod 2 17 under the rotation of rotating rod. Rotating plate 4 21 receives the rotational force of rotating rod, thereby rotating, thereby limiting the movement of moving rod 2 17. The outside of fixed block 14 is slidably connected to the top of connecting shell 25. Busbar is detached from connecting shell 25, thereby moving with fixed block 14.

[0035] Working principle: The operator places the busbar in the placement slot and moves the moving block 12, which in turn moves the moving rod 11, thereby moving the push plate 10, which in turn moves the moving plate 9, which in turn rotates the rotating plate 8, causing the rotating plate 6 to rotate, and the fixing plate 5 to rotate, guiding the rotating plate 3 to rotate, thus causing the force plate 4 to lock the busbar. At this time, the limiting block 7 inside the moving block 12 is locked in the limiting groove of the groove plate 13. When it is necessary to release the busbar, simply move the two moving plates 2 closer together, causing the limiting block 7 to move, thereby fixing the busbar. In addition, it facilitates installation and maintenance, improves work efficiency, and makes the internal layout of the distribution cabinet more regular, which is conducive to the safe operation of the overall equipment.

[0036] The fixed block 14 moves, causing the force-applying block 15 to move, which in turn moves the inclined plate 16, thus moving the second moving rod 17. Then, the motor 19 is started, which drives the second rotating rod to rotate, causing the fourth rotating plate 21 to rotate, thereby limiting the movement of the second moving rod 17. At this time, the spring on the third moving rod 22 is stretched. When the motor 19 reverses, the spring releases its force, thus guiding the movement of the second moving rod 17 to move. This achieves the rapid installation of the busbar, enhances equipment stability, reduces the risk of failure, facilitates later maintenance and upgrades, and improves overall safety.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
