[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The clamping rod slides along the second circular plate to the rear side of the first circular plate, thereby disengaging the clamping rod from the first circular plate, thereby quickly disengaging the second circular plate and the third circular plate from moving toward the first circular plate, and the third circular plate fits in the inner groove of the first circular plate, thereby making the second circular plate fit in the first circular plate. After the second circular plate and the first circular plate fit, the clamping rod moves along the inclined surface of the second circular plate, and at the same time, the clamping rod compresses the coarse spring. Since the diameter of the thin spring is smaller, the thin spring will be compressed first, and the coarse spring will be compressed later. The clamping rod slides along the second circular plate to the rear side of the first circular plate, thereby disengaging the clamping rod from the first circular plate, thereby quickly disassembling the power supply group rack, and facilitating the maintenance of electrical components on the power supply group rack.

[0017] 2. The present application causes 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. 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 opened inside the piston plate, when the piston plate descends, the buffer solution flows from the inside of multiple through holes to form a damping effect, thereby buffering the moving block and improving stability, which is conducive to moving the power supply group rack downward, making it convenient for the electrical components installed on the power supply group rack to descend, and convenient for the staff to repair it. The position of the power supply group rack is lowered to facilitate the staff to operate.

[0018] 3. In the present application, when the power supply group rack moves forward and descends, the wires are stretched, thereby causing the support rod to flip forward, thereby driving the swing arm to flip. When the swing arm flips forward, it drives the support rod to flip, causing the support rod to drive the pull rod forward, thereby driving the fixed block and the guide block to slide inside the cabinet, causing the guide block to compress 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.

The front sides of the two second circular plates 15 are fixedly connected to the third circular plate 16. The two third circular plates 16 are fixedly connected to the third circular plate 16. The three circular platforms 16 are respectively sleeved on the outside of the two connecting shafts 13, and the two ends of the top of the front side of the rear support plate 5 are fixedly connected with positioning blocks 23. The upper and lower sides of the two positioning blocks 23 are fixedly connected with sliding sleeves 19. The four sliding sleeves 19 are slidably connected with clamping rods 20. The four clamping rods 20 correspond to the two first circular platforms 14, the second circular platform 15 and the third circular platform 16 respectively. The third limit spring 55 is fixedly connected to the positioning block 23. The first circular platform 14 corresponds to the third limit spring 55. The outside of the connecting shaft 13 is fixedly connected with a baffle. A limiting groove 18 is provided inside the first circular platform 14. A thin spring 17 is fixedly connected to the inside of the limiting groove 18, and the thin spring 17 is fixedly connected to the third circular plate 16 at one end away from the first circular plate 14. The first circular plate 14 is provided with a groove on the side facing the third circular plate 16, and the third circular plate 16 is adapted to the groove, so that the sliding sleeve 19 is conveniently fitted with the first circular plate 14. A thick spring 21 is provided inside the four sliding sleeves 19, and the two ends of the four thick springs 21 are fixedly connected to the four sliding sleeves 19 and the clamping rod 20 respectively, so as to facilitate supporting the clamping rod 20, so that the four sliding sleeves 19 of the clamping rod 20 are fixedly connected to the knob 22 at one end facing the outer side of the positioning block 23.

[0038] The two upper slide bars 26 are fixed to the outer ends of the two moving blocks 24, and the two lower slide bars 26 are fixed to the outer ends of the two moving blocks 24. The first limit spring 28 supports the slide bar 27 and the second limit spring 28 supports the slide bar 27. The front ends of the two upper slide bars 26 are fixedly connected to the first guide rod 35, and the rear ends of the two slide bars 27 are fixedly connected to the second guide rod 36. The two cross plates 25 are rotatably connected to the rotating shaft 33, and the outer ends of the two rotating shafts 33 are fixedly connected to the guide plates 34. The two first guide rods 35 and the second guide rods 36 respectively penetrate the two inner ends of the guide plates 34 and are slidably connected to the two guide plates 34. When the upper slide bar 26 moves forward, the guide plate 34 is flipped by the first guide rod 35, thereby driving the slide bar 27 to move backward.

[0039] The two first push plates 31 are slidably connected to the interior of the two slide rails 38, and the two first push plates 31 are fixedly connected to the top of the two first vertical rods 40.

[0040] A round rod 44 is fixedly connected to the rear side of the interior 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 a pull rod 47 on the opposite side. The bottom ends of the two pull rods 47 are fixedly connected to the opposite side of the limit plate 48. The two limit plates 48 pass through the two swing arms 45 respectively and are slidably connected to the two swing arms 45. The rear sides of the two fixed blocks 52 are fixedly connected to guide blocks 53. The two guide blocks 53 pass through the rear of the cabinet 1. The two sides of the wall are slidably connected to the cabinet 1, and the second vertical rods 50 are fixedly connected on both sides of the inner side wall of the cabinet 1. The outside of the two second vertical rods 50 are sleeved with second buffer springs 51, and the two second buffer springs 51 are respectively fitted with two guide blocks 53 and the cabinet 1. A plurality of wires 49 are fixedly connected to the rear side of the power supply group rack 3, and the plurality of wires 49 are all wound around the outside of the support rod 46. The plurality of wires 49 all pass through the rear support plate 5 and the cabinet 1 and are movably connected to the rear support plate 5 and the cabinet 1. A cabinet door 54 is hinged on the front side of the cabinet 1, and the wires 49 are supported by the support rod 46.

[0041] When this solution is in use, when maintenance is required, after opening the cabinet door 54, if the electrical components on the power distribution rack 2 need to be repaired, the power distribution rack 2 can be repaired directly. 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 so that the power supply group rack 3 moves 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 circular plate 16 to move inwardly of the positioning block 23, so that the third circular plate 16 pushes the two clamping rods 20 to retract into the two sliding sleeves 19, thereby causing the clamping rod 20 to compress the thick spring 21, and at the same time the clamping rod 20 moves along the inclined surface of the third circular plate 16 toward the direction of the second circular plate 15. When the second circular plate 15 moves to the rear side of the clamping rod 20, it pulls the power supply group frame 3 forward, so that the power supply group frame 3 drives the connecting block 12 forward, and then the connecting rod 20 is connected to the power supply group frame 3. The connecting shaft 13 drives the second circular plate 15 to move forward synchronously. When the second circular plate 15 moves forward, the second circular plate 15 contacts the clamping rod 20. The clamping rod 20 pushes the second circular plate 15 and the third circular plate 16 to slide on the outside of the connecting shaft 13, so that the second circular plate 15 and the third circular plate 16 move toward the first circular plate 14. The third circular plate 16 fits into the inner groove of the first circular plate 14, thereby fitting the second circular plate 15 to the first circular plate 14. After the frustum plate 14 is fitted, the clamping rod 20 moves along the inclined surface of the second frustum plate 15, and at the same time the clamping rod 20 compresses the coarse spring 21. Since the diameter of the thin spring 17 is smaller, the thin spring 17 will be compressed first, and the coarse spring 21 will be compressed later. The clamping rod 20 slides along the second frustum plate 15 to the rear side of the first frustum plate 14, thereby disengaging the clamping rod 20 from the first frustum plate 14, thereby quickly removing the power supply group rack 3, making it easier to inspect and repair the electrical components on the power supply group rack 3.

[0042] The second guide rod 35 is moved by the second push plate 32, and the second guide rod 35 is driven by the second push plate 32 to move, thereby driving the second guide rod 35 to move and the second guide rod 35 to drive the guide plate 34 to flip, thereby driving the second guide rod 36 and the lower slide rod 27 to move backward, so that the lower slide rod 27 is disengaged from the inside of the card slot 39. After the lower slide rod 27 is disengaged from the card slot 39, the movable plate 8 is moved to the inside of the card slot 30 and is fitted with the card slot 30. The movable block 24 slides downward along the vertical slot 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 provided inside the piston plate 41, when the piston plate 41 descends, the buffer solution flows from the inside of the multiple through holes to form a damping effect, thereby buffering the movable block 24 and improving stability, which is conducive to moving the power supply group rack 3 downward, making it convenient for the electrical components installed on the power supply group rack 3 to descend, and convenient for the staff to repair it. The position of the power supply group rack 3 is lowered for the convenience of the staff to operate.

[0043] When the power supply group rack 3 moves forward and descends, the 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 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 wire 49 is straightened, which facilitates the movement of the electrical components on the power supply group rack 3.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
