A limit plate is slidably connected inside the fixing block. A first plug-in rod with both ends penetrating the fixing block is fixedly connected to the limit plate. A first drive plate is provided at the end of the first plug-in rod away from the first side plate. A first spring is sleeved on the outer side of the first plug-in rod inside the fixing block. The two ends of the first spring are fixedly connected to the inner side wall of the fixing block and the limit plate, respectively. A second plug-in rod is slidably connected to one side of the fixing block. One end of the second plug-in rod extends to the outer side of the fixing block and is provided with a second drive plate. A second spring is sleeved on the second plug-in rod outside the fixing block. One end of the second spring is fixedly connected to the outer side wall of the fixing block, and the other end of the second spring is fixedly connected to the second drive plate.

[0007] As a further explanation of this utility model, the upper panel and the lower panel are fixedly connected by a plurality of evenly distributed support columns.

Second sliders 1301 are symmetrically provided on the upper and lower sides of the second side plates 13. Two opposing first side plates 14 are slidably connected to the lower panel 11 outside the second side plates 13. First sliders 1401 are symmetrically provided on the upper and lower sides of the first side plates 14. A fixing block 15 is provided on the outer wall of the first side plates 14. A limit plate 1501 is slidably connected inside the fixing block 15. A first insertion rod 1502, with both ends penetrating the fixing block 15, is fixedly connected to the limit plate 1501. A first drive plate 1503 is provided at one end of the first plug rod 1502 away from the first side plate 14. A first spring 1504 is sleeved on the outside of the first plug rod 1502 inside the fixing block 15. The two ends of the first spring 1504 are fixedly connected to the inner side wall of the fixing block 15 and the limiting plate 1501, respectively. A second plug rod 1505 is slidably connected to one side of the fixing block 15. A second drive plate 1506 is provided at one end of the second plug rod 1505 extending to the outside of the fixing block 15. A second spring 1507 is sleeved on the second plug rod 1505 outside the fixing block 15. One end of the second spring 1507 is fixedly connected to the outer side wall of the fixing block 15, and the other end of the second spring 1507 is fixedly connected to the second drive plate 1506.

[0028] The upper panel 12 and the lower panel 11 are fixedly connected by a plurality of evenly distributed support columns 16.

[0029] Furthermore, a first sliding groove 1101 for the displacement of the first slider 1401 is provided on the top end surface of the lower panel 11 and the bottom end surface of the upper panel 12. A second sliding groove 1102 for the displacement of the second slider 1301 is provided on the top end surface of the lower panel 11 and the bottom end surface of the upper panel 12 inside the first sliding groove 1101. The second sliding groove 1102 is offset from the first sliding groove 1101.

[0030] Furthermore, the first side plate 14 has a through hole 1402 for inserting the first plug rod 1502, and the second side plate 13 has a second hole 1302 for inserting the first plug rod 1502.

[0031] Furthermore, the first plug rod 1502 has a first locking hole 1508 through which the second plug rod 1505 can be inserted in the first spring 1504 in its natural state, and a second locking hole 1509 through which the second plug rod 1505 can be inserted in the first spring 1504 in its compressed state.

[0032] Furthermore, the inner sidewall of the fixing block 15 is provided with a stop block 1510 for limiting the position of the limiting plate 1501.

[0033] refer to Figure 8 When the busbar trunking is working normally, the first spring 1504 and the second spring 1507 are both in their natural state. The front end of the first plug rod 1502 is locked in the first fixing hole 1402 on the first side plate 14 and the second fixing hole 1302 on the second side plate 13, thereby locking the first side plate 14 and the second side plate 13, so that the busbar trunking housing 1 is firmly and reliably connected as a whole.

[0034] refer to Figure 9 When the busbar trunking is being repaired, the second spring 1507 is in its natural state, and the first plug rod 1502 is locked by the second plug rod 1505, causing the first spring 1504 to be in a compressed state. The front end of the first plug rod 1502 is locked in the fixing block 15, and at the same time, the locking of the first side plate 14 and the second side plate 13 is released. The staff can slide the first side plate 14 and the second side plate 13 as needed to carry out maintenance inside the busbar trunking.

[0035] The working principle of this utility model:

[0036] When maintenance is required on the busbar trunking, the operator first pulls the second drive disc 1506 outward. The second drive disc 1506 drives the second plug rod 1505 to move synchronously until the front end of the second plug rod 1505 is completely disengaged from the first locking hole 1508 on the first plug rod 1502. At the same time, the second spring 1507 is stretched and undergoes elastic deformation. Then, the operator pulls the first drive disc 1503 outward. The first drive disc 1503 drives the first plug rod 1502 to move synchronously until the limiting plate 1501 on the first plug rod 1502 abuts against the stop block 1510. At the same time, the first spring 1504 is compressed and undergoes elastic deformation. At this point, the second spring 1504... The front end of the first plug rod 1502 is completely retracted into the fixing block 15, and the second plug rod 1505 is aligned with the second locking hole 1509 on the first plug rod 1502. When the second drive plate 1506 is released, the second spring 1507 rebounds under the elastic action, causing the second plug rod 1505 to pass through the second locking hole 1509. Then, the first drive plate 1503 is released, which locks the front end of the first plug rod 1502 into the fixing block 15. At the same time, the locking of the first side plate 14 and the second side plate 13 is released. The operator can slide the first side plate 14 or the second side plate 13 as needed to carry out maintenance inside the busbar trunking.

[0037] After the maintenance work is completed, slide the first side plate 14 and the second side plate 13 back to their original positions, and pull the second drive disc 1506 outward so that the front end of the second plug rod 1505 is completely disengaged from the second locking hole 1509 on the first plug rod 1502. Since the first plug rod 1502 is unlocked, the first spring 1504 rebounds under the elastic action, causing the first plug rod 1502 to be inserted into the first fixing hole 1402 on the first side plate 14 and the second fixing hole 1302 on the second side plate 13 in sequence. At this time, the second plug rod 1505 is aligned with the first locking hole 1508 on the first plug rod 1502. Release the second drive disc 1506, and the second spring 1507 rebounds under the elastic action, causing the second plug rod 1505 to pass through the first locking hole 1508, thereby locking the front end of the first plug rod 1502 in the first fixing hole 1402 and the second fixing hole 1302, and thus locking the first side plate 14 and the second side plate 13.
