[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 2 to Figure 8 As shown, this embodiment proposes a switch cabinet that is easy to maintain, and its structure includes a cabinet body 1. The first cabinet outlet 11 in this embodiment is arranged on the side wall of the cabinet body 1, the storage cavity 12 is arranged in the cabinet body 1, a plurality of first placement racks 4 are arranged in the storage cavity 12, and the first accommodating drawer 21 is arranged in the first placement rack 4. The transport structure is arranged in the storage cavity 12, and is used to transport each first accommodating drawer 21 from the first placement rack 4 to the first cabinet outlet 11 or from the first cabinet outlet 11 to the first placement rack 4. The control structure is arranged in the storage cavity 12, and is used to transport each first accommodating drawer 21 to be close to the first placement rack 4 or to be transported away from the first placement rack 4.

[0034] The transport structure in this embodiment includes a transmission chain 33, which is arranged on the inner wall of the storage cavity 12, a transport member is arranged on the transmission chain 33, a placement groove 41 is arranged on the first placement rack 4, and the first receiving drawer 21 is arranged in the placement groove 41 and is slidably connected with the placement groove 41. The first placement rack 4 in this embodiment is arranged at one end of the transmission chain 33, and the first cabinet outlet 11 is arranged at the other end of the transmission chain 33. The first receiving drawer 21 is arranged in an array along the vertical direction. When the transport member on the transmission chain 33 passes by, the first receiving drawer 21 on the first placement rack 4 can be separated from the first placement rack 4 and transported to the first cabinet outlet 11. Such a design allows the first receiving drawer 21 to be transported to the first cabinet outlet 11 for maintenance by the transport member even if it is on a high floor, which facilitates the maintenance work.

[0035] In this embodiment, the first sliding rod 31 and the second sliding rod 32 are arranged in the storage cavity 12, the first sliding rod 31 and the second sliding rod 32 are parallel to each other, the sliding member 3 is slidingly arranged on the first sliding rod 31 and the second sliding rod 32, the sliding member 3 is provided with a sliding hole 34, and the transport member includes a first sliding block 341, the first sliding block 341 is rotatably connected to the transmission chain 33, the first sliding block 341 is slidably connected to the sliding hole 34, the first sliding block 341 is a rectangular structure, and the sliding direction of the first sliding block 341 on the sliding hole 34 is parallel to the horizontal plane. Such a design allows the transport member to slide in the sliding hole 34, so that the transport member always remains parallel to the horizontal plane during transportation, ensuring that the first storage drawer 21 will not fall due to tilting when transporting the first storage cabinet, making the transportation more stable and reliable.

[0036] In this embodiment, a plurality of transport rods 342 are fixedly arranged on the first sliding block 341, and each transport rod 342 is provided with a gap, and each transport rod 342 is on the same horizontal plane. The cross section of each transport rod 342 is a circular structure. In this embodiment, an anti-skid layer can also be arranged on the transport rod 342, and the first anti-skid layer is made of rubber material, which is used to strengthen the friction between the first receiving drawer 21 and the transport rod 342 during transportation, and prevent the first receiving drawer 21 from being separated from the transport rod 342 due to transportation. Such a design enables the first receiving drawer 21 originally on the first placement rack 4 to be lifted and transported to the first cabinet outlet 11 due to the upward movement of the lower transport rod 342. Such a design can be rotated by the transmission chain 33 to place or transport the first receiving drawer 21.

[0037] The control structure in this embodiment includes a sliding rail 5, which is fixedly connected to the storage cavity 12, a first sliding groove 51 is arranged in the sliding rail 5, and the first placement rack 4 is slidingly connected to the first sliding groove 51, so as to prevent the first placement rack 4 from sliding and deviating. The adjusting screw rod 511 is rotatably arranged in the first sliding groove 51, the adjusting screw rod 511 is threadedly connected to the first placement rack 4, the driving motor 512 is fixedly arranged in the storage cavity 12, and the output shaft of the driving motor 512 is fixedly connected to the adjusting screw rod 511. In this embodiment, the displacement of the first placement rack 4 is controlled by rotating the adjusting screw rod 511. Since the rotation stroke of the adjusting screw rod 511 is much greater than the displacement stroke of the first placement rack 4, the first placement rack 4 will be docked more accurately and reliably, which is convenient for the first accommodating drawer 21 on the first placement rack 4 to be transported and the first accommodating drawer 21 to be electrically connected to the cabinet 1 again. Such a design enables the first storage rack 4 to move toward the transmission chain 33 by controlling the adjusting screw rod 511 through the driving motor 512, so that when the first storage drawer 21 is transported by the transport member, other first storage drawers 21 will not appear on the transport path to prevent them from blocking the transportation of the first storage drawer 21.

[0038] In this embodiment, a plurality of first material transport notches 411 are arranged at the bottom of the placement slot 41, and each first material transport notch 411 corresponds to a transport rod 342 one by one, and the transport rod 342 is slidably connected to the first material transport notch 411, so as to facilitate the passage of the transport rod 342, so that the first receiving drawer 21 originally on the first placement rack 4 can be lifted off the first placement rack 4 by the transport rod 342, so as to facilitate the transportation of the first receiving drawer 21. The second material transport notch 412 is arranged at the end of the placement slot 41 near the sliding member 3, so as to facilitate the transportation of the transport rod 342. An anti-skid layer is fixed at the bottom of the placement slot 41, and the anti-skid layer is made of rubber material, so as to prevent the first receiving drawer 21 from slidingly deviating at the bottom of the placement slot 41 due to the movement of the first placement rack 4.

[0039] The second placement rack 7 in this embodiment is arranged in the storage cavity 12 near the first cabinet outlet 11, and a plurality of placement rods 71 ​​are rotatably arranged at the bottom of the second placement rack 7 to facilitate the taking out or putting in of the first receiving drawer 21. A placement gap 711 is arranged between each placement rod 71, and the placement gap 711 corresponds to the transport rod 342 one by one, and the projection surface of each placement gap 711 in the vertical direction coincides with the projection surface of each placement rod 71 in the vertical direction, so that when the transport member transports the first receiving drawer 21 from top to bottom to the second placement rack 7, the first receiving drawer 21 can be placed on the second placement rack 7, so as to facilitate the operation of extracting and pushing the second receiving drawer 22. The cross section of the placement rod 71 is a circular structure, and an anti-skid layer is wrapped and fixed on the placement rod 71, and the anti-skid layer is made of rubber material. The design of the anti-slip layer can not only increase the friction between the first receiving drawer 21 and the placement rod 71 to prevent the first receiving drawer 21 from jumping during the process of being pulled out or placed, but also buffer the impact force on the placement rod 71 when the first receiving drawer 21 enters the placement rod 71.

[0040] The first receiving drawer 21 in this embodiment is a rectangular structure, and the receiving groove 212 is arranged at the top of the first receiving drawer 21 for installing electrical components. The first receiving drawer 21 is slidably connected to the first cabinet outlet 11, and the first limiting members 2121 are arranged on both sides of the first receiving drawer 21 away from the first cabinet outlet 11. Each first limiting member 2121 abuts against the first cabinet outlet 11 to prevent the first receiving drawer 21 from being separated from the first cabinet outlet 11 when being drawn out, thereby causing inconvenience in reinstallation. The handle 211 is fixedly arranged on the side of the first receiving drawer 21 close to the first cabinet outlet 11 to facilitate the extraction or placement of the first receiving drawer 21 into the first cabinet outlet 11.

[0041] In this embodiment, a first contact can be fixedly arranged at the bottom of the first receiving drawer 21, a second contact is arranged in the placement groove 41, the first contact and the second contact are in contact, a plug is arranged at the end of the first placement rack 4 away from the first receiving drawer 21, the plug is electrically connected to the second contact, and a jack is arranged at the end of the first sliding groove 51 away from the first receiving drawer 21, and the plug is plugged into the jack. When the first receiving drawer 21 enters the placement groove 41, the first contact and the second contact are in contact. When the first placement rack 4 is controlled by the driving motor 512 to make the tap plug into the jack, the first receiving drawer 21 is electrically connected to the cabinet 1, so that the electrical components in the first receiving drawer 21 can work normally. In this embodiment, a second contact can also be arranged at the first cabinet outlet 11, so that the first receiving drawer 21 can conduct electricity normally after it is out of the cabinet, which is convenient for its maintenance work.

[0042] In this embodiment, a plurality of second cabinet outlets 13 are arranged at the lower end of the first cabinet outlet 11, and each second cabinet outlet 13 is slidably connected with a second accommodating drawer 22, a second limiting member 6 is fixedly arranged at the end of the second cabinet outlet 13 away from the second accommodating drawer 22, a second sliding groove 61 is arranged in the second limiting member 6, a third sliding block 9 is slidably arranged in the second sliding groove 61, and a limiting groove 92 is arranged at the top of the third sliding block 9. The limiting groove 92 is a heart-shaped structure. In this embodiment, the heart-shaped limiting groove 92 is adopted so that when the limiting rod 93 slides in the limiting groove 92, two "V"-shaped bayonet holes will appear in a row, and when the limiting rod 93 enters the "V"-shaped bayonet hole and is no longer subjected to external force, it will be stuck in the bayonet hole without sliding or deviating. The limiting rod 93 is rotatably arranged on the third sliding block 9, and the other end of the limiting rod 93 is slidably connected with the limiting groove 92. The limiting plate 221 is fixedly arranged at the bottom of the second receiving drawer 22 near the end of the second limiting member 6, and the rotating rod 8 is rotatably arranged at the bottom of the second limiting member 6. The abutting block 82 is fixedly arranged at the other end of the rotating rod 8, and the abutting block 82 abuts against the limiting plate 221, and is used to abut against the second receiving drawer 22, so that the second receiving drawer 22 will not slide out under the limit of the abutting block 82, effectively preventing the electrical components in the second receiving drawer 22 from being affected by dust in the external environment during normal operation. The connecting rod 91 is fixedly arranged at the bottom of the third sliding block 9, and the third sliding groove 81 is arranged on the rotating rod 8, and the connecting rod 91 is slidably connected with the third sliding groove 81. When the limiting rod 93 is in the limiting groove 92 near the snap-in opening of the second cabinet outlet 13, the second accommodating drawer 22 is limited by the abutment block 82 and the second accommodating drawer 22 is difficult to be pulled out; when the second accommodating drawer 22 is pushed again so that the limiting rod 93 enters another snap-in opening in the limiting groove 92, the abutment block 82 disengages from the second accommodating drawer 22 and the second accommodating drawer 22 can be pulled out.

[0043] The limiting spring 94 in this embodiment is arranged in the second sliding groove 61 away from the end of the second receiving drawer 22, and the two ends of the limiting spring 94 are respectively fixedly connected to the side wall of the second sliding groove 61 and the third sliding block 9. Such a design allows the limiting rod 93 to be retained on the two bayonet holes in the limiting groove 92 under the action of the limiting spring 94 without being affected by external forces, so as to facilitate the control of limiting or disengaging the second receiving drawer 22.

[0044] The working process of this embodiment is as follows: when it is necessary to repair the high-level first receiving drawer 21, start the drive motor 512 corresponding to the first receiving drawer 21 to be repaired, and drive the first placement rack 4 and the first receiving drawer 21 to move toward the transmission chain 33 by adjusting the screw rod 511. At this time, start the transmission chain 33 to move the transport member, and the first receiving drawer 21 is separated from the first placement rack 4 and enters the second placement rack 7 through the transport rod 342 on the transport member. At this time, the first receiving drawer 21 can be pulled out for repair through the handle 211; when the first receiving drawer 21 is repaired, first return the first receiving drawer 21 to the second placement rack 7, and then start the transmission chain 33 in the reverse direction, so that the first receiving drawer 21 is transported from the second placement rack 7 to the first placement rack 4, and then start the drive motor 5 in the reverse direction. 12, so that the first accommodating drawer 21 returns to its original position; when the second accommodating drawer 22 on the lower layer needs to be repaired, the second accommodating drawer 22 that needs to be repaired is first pushed inward, and the third sliding block 9 is pushed to move. At this time, the limit rod 93 slides in the limit groove 92, so that the limit rod 93 box moves in the direction away from the second accommodating drawer 22. At this time, the abutment block 82 on the rotating rod 8 is disengaged from the limit plate 221, and the second accommodating drawer 22 is moved out of the second cabinet outlet 13; when the maintenance work on the second accommodating drawer 22 is completed, the second accommodating drawer 22 is pushed to move inward. At this time, the third sliding block 9 moves, and the limit rod 93 moves in the limit groove 92 in the direction close to the second accommodating drawer 22. At this time, the abutment block 82 on the rotating rod 8 abuts against the limit plate 221, and the second accommodating drawer 22 will not slide out.
