[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention enables the connecting shaft to drive the second circular table plate to move forward synchronously. When the second circular table plate moves forward, the second circular table plate contacts the clamping rod, and the clamping rod pushes the second circular table plate and the third circular table plate to slide on the outside of the connecting shaft, so that the second circular table plate and the third circular table plate move toward the first circular table plate, and the third circular table plate fits with the internal groove of the first circular table plate, thereby making the second circular table plate fit with the first circular table plate. After the second circular table plate and the first circular table plate fit, the clamping rod moves along the inclined surface of the second circular table plate, and at the same time, the clamping rod compresses the thick spring. Since the diameter of the thin spring is smaller, the thin spring will be compressed first, and the thick spring will be compressed later. The clamping rod slides along the second circular table plate to the rear side of the first circular table plate, thereby disengaging the clamping rod from the first circular table plate, thereby quickly disassembling the power supply group rack, which is convenient for repairing the electrical components on the power supply group rack.

[0016] 2. The present application enables the moving block to drive the first push plate to descend, and the first push plate drives the first vertical rod to descend when descending, and the first vertical rod compresses the first buffer spring when descending, and at the same time, the side plate drives the piston plate to slide down inside the piston sleeve when descending. Since a through hole is provided inside the piston plate, when the piston plate descends, the buffer solution flows through multiple through holes to form a damping effect, thereby buffering the moving block and improving stability, which is beneficial to moving the power supply group rack downward, facilitating the lowering of electrical components installed on the power supply group rack, facilitating the staff to inspect and repair it, and lowering the position of the power supply group rack for the convenience of staff to operate.

[0017] 3. In the present application, when the power supply group rack moves forward and descends, the wires are stretched, so that the support rod flips toward the front side, thereby driving the swing arm to flip. When the swing arm flips forward, it drives the support rod to flip, so that the support rod drives the pull rod forward, thereby driving the fixed block and the guide block to slide inside the cabinet, so that the guide block compresses the second buffer spring, thereby moving the support rod forward, thereby straightening the wires, and facilitating the movement of electrical components on the power supply group rack.

[0024] A round rod 44 is fixedly connected to the rear side of the cabinet 1, and a pull rod 47 is rotatably connected to the outer sides of the two ends of the round rod 44. A support rod 46 is fixedly connected between the tops of the two pull rods 47. Fixed blocks 52 are provided at both ends of the front top of the rear support plate 5. The two fixed blocks 52 are hinged with pull rods 47 on the opposite sides respectively. The bottom ends of the two pull rods 47 are fixedly connected to the opposite sides of the limit plates 48.

[0025] When the present solution is used, when maintenance is required, after the cabinet door 54 is opened, if the electrical components on the power distribution rack 2 are to be repaired, the power distribution rack 2 can be directly repaired. However, when the electrical components on the power supply group rack 3 need to be repaired, the operator pushes the power supply group rack 3 into the cabinet 1 to move the power supply group rack 3 toward the rear support plate 5. When the power supply group rack 3 moves, it drives the connecting block 12 and the connecting shaft 13 to move, and then the connecting shaft 13 and the first round table plate 14 move toward the positioning block 2. 3, and the connecting shaft 13 drives the third round table plate 16 to move inwardly of the positioning block 23, so that the third round table plate 16 pushes the two clamping rods 20 to contract inside the two sliding sleeves 19, so that the clamping rod 20 compresses the thick spring 21, and at the same time, the clamping rod 20 moves along the inclined surface of the third round table plate 16 toward the direction of the second round table plate 15. When the second round table plate 15 moves to the rear side of the clamping rod 20, the power supply group frame 3 is pulled forward, so that the power supply group frame 3 drives the connecting block 12 to move forward, and the connecting rod 20 is connected to the second round table plate 15. The connecting shaft 13 drives the second round table plate 15 to move forward synchronously. When the second round table plate 15 moves forward, it contacts the clamping rod 20. The clamping rod 20 pushes the second round table plate 15 and the third round table plate 16 to slide on the outside of the connecting shaft 13, so that the second round table plate 15 and the third round table plate 16 move toward the first round table plate 14. The third round table plate 16 fits with the inner groove of the first round table plate 14, thereby fitting the second round table plate 15 with the first round table plate 14. After the truncated cone plate 14 is fitted, the clamping rod 20 moves along the inclined surface of the second truncated cone plate 15, and at the same time, the clamping rod 20 compresses the thick spring 21. Since the diameter of the thin spring 17 is smaller, the thin spring 17 will be compressed first, and the thick spring 21 will be compressed later. The clamping rod 20 slides along the second truncated cone plate 15 to the rear side of the first truncated cone plate 14, so that the clamping rod 20 is disengaged from the first truncated cone plate 14, so that the power supply group frame 3 can be quickly removed, which is convenient for the inspection and maintenance of the electrical components on the power supply group frame 3.

[0026] By pulling the power supply group frame 3 to move forward, the power supply group frame 3 drives the moving plate 6 and the clamping plate 8 to move, so that the clamping plate 8 drives the sliding block 9 to move, and the sliding block 9 slides inside the transverse groove 10, so that the clamping plate 8 moves to the inside of the clamping block 30 and fits with the clamping block 30. At the same time, the clamping plate 8 drives the second push plate 43 to push the top plate 32 to move, so that the top plate 32 pushes the upper slide bar 26 to move, and the upper slide bar 26 moves to compress the second limit spring 29, so that the upper slide bar 26 drives the first guide rod 35 to move, so that the first guide rod 35 drives the guide plate 34 to flip, and thereby drives the second guide rod 36 and the lower slide rod 27 to move backward, so that the lower slide rod 27 disengages from the inside of the clamping slot 39, and after the lower slide rod 27 disengages from the clamping slot 39, the moving The movable block 24 slides downward along the vertical groove 11, and then the movable block 24 drives the first push plate 31 to descend. When the first push plate 31 descends, it drives the first vertical rod 40 to descend. When the first vertical rod 40 descends, it compresses the first buffer spring 42. At the same time, when the side plate 4 descends, it drives the piston plate 41 to slide down inside the piston sleeve 37. Since a through hole is opened inside the piston plate 41, when the piston plate 41 descends, the buffer solution flows through the multiple through holes to form a damping effect, thereby buffering the movable block 24 and improving stability, which is beneficial to moving the power supply group frame 3 downward, making it convenient for the electrical components installed on the power supply group frame 3 to descend, and convenient for the staff to repair it. The position of the power supply group frame 3 is lowered for the convenience of the staff to operate.

[0027] When the power supply group rack 3 moves forward and descends, the electric wire 49 is stretched, so that the support rod 46 flips forward, thereby driving the swing arm 45 to flip. When the swing arm 45 flips forward, it drives the support rod 46 to flip, so that the support rod 46 drives the pull rod 47 to move forward, and then drives the fixed block 52 and the guide block 53 to slide inside the cabinet 1, so that the guide block 53 compresses the second buffer spring 51, so that the support rod 46 moves forward, and then the electric wire 49 is straightened, so as to facilitate the movement of the electrical components on the power supply group rack 3.

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
