[0032] The fireproof casing 1 of the busbar trunking has symmetrically opened side sliding grooves 201 on both end faces. The top of the fireproof casing 1 of the busbar trunking has a limit groove 202. Sliding blocks 203 are slidably installed on the inner side of the side sliding grooves 201. There are two sliding blocks 203. The two sliding blocks 203 are symmetrically installed on the inner side of the side sliding grooves 201 on both sides of the fireproof casing 1 of the busbar trunking for easy and accurate positioning. A rotating column 204 is welded to the side end face of the sliding block 203. A rotating block 205 is rotatably sleeved on the outer side of the rotating column 204. A movable groove is opened on the inner side of the rotating block 205. The rotating block 205 is rotatably connected to the rotating column 204 through the movable groove for easy rotation of the rotating groove plate 206. A rotating groove plate 206 is welded to one end face of the rotating block 205.

[0033] The inner side of the rotating slot plate 206 is provided with a snap-fit ​​groove 207, the top of the rotating slot plate 206 is welded with a positioning plate 208, and a clamping sleeve 209 is welded to one side end face of the rotating slot plate 206. A clamping screw 210 is threadedly connected to the inner side of the clamping sleeve 209.

[0034] A limiting screw 211 is embedded in the inner side of the sliding block 203. A washer 212 is sleeved on the outer end of the limiting screw 211. A limiting groove 202 is opened through the inner side of the busbar fireproof shell 1 at the position corresponding to the limiting screw 211. The outer diameter of the limiting screw 211 is equal to the inner diameter of the washer 212, which is conducive to fixing the sliding block 203. A limiting nut 213 is threadedly connected to the outer side of the limiting screw 211.

[0035] A protective component 3 is installed at one end of the fireproof casing 1 of the bus trunking;

[0036] The protective component 3 includes a snap-fit ​​block 301, a magnet 302, an insert groove 303, a protective shell 304, and a grip 305;

[0037] A snap-fit ​​block 301 is snapped into the inner side of the side sliding groove 201, and a magnet 302 is sleeved on the outer side of the snap-fit ​​block 301. An embedding groove 303 is formed on the inner side of the two snap-fit ​​blocks 301. A protective shell 304 is welded to one end face of the snap-fit ​​block 301. A protective chamber is opened on the inner side of the protective shell 304. The embedding groove 303 is connected to the protective chamber inside the protective shell 304, which is beneficial to protect the copper sheet. A handle 305 is welded to the top of the protective shell 304.

[0038] The working principle and usage process of this utility model are as follows: First, after the operator installs the fireproof casing 1 of the busbar trunking, when a new busbar trunking connection is needed, the new fireproof casing 1 of the busbar trunking is inserted into the inner position of the snap-fit ​​groove 207. At this time, one side of the new fireproof casing 1 of the busbar trunking is aligned with the positioning plate 208. Then, the operator tightens the clamping screws 210 on the inner side of the clamping sleeves 209 on both sides. At this time, the two clamping screws 210 can quickly clamp and fix the new fireproof casing 1 of the busbar trunking. At this time, one end of the new fireproof casing 1 of the busbar trunking will be fixed in the inner position of the snap-fit ​​groove 207. Then, the two sliding blocks 203 and the two sliding blocks 204 are slid. 03 will slide inside the side sliding groove 201, and at this time, the limit screws 211 on both sides will slide to the other side inside the limit groove 202. Then, the new busbar fireproof shell 1 will move precisely to the fixed busbar fireproof shell 1. At this time, the copper pieces inside the busbar fireproof shell 1 will automatically align, so as to facilitate the interconnection between the copper pieces. Then tighten the limit nut 213 to fix the position. No manual alignment is required. Whether the busbar is erected at high altitude or laid on the ground, the connection steps are simplified. The precise connection can prevent the copper pieces from colliding and being damaged. It can prevent short circuits and fires at the damaged parts during subsequent use, further increasing the safety of the busbar.

[0039] Next, before transporting the busbar trunking, insert the snap-fit ​​block 301 into the inner side of the side sliding groove 201. Then, the copper sheet of the busbar trunking will enter the interior of the embedded groove 303, and after the magnet 302 contacts the fireproof shell 1 of the busbar trunking, it will be attracted to its side. At this time, the protective shell 304 can be fixed. This can prevent collision damage to the copper sheet during transportation, further protect the busbar trunking, and reduce transportation damage. When installation is required, simply pull the handle 305 to quickly engage the protection, making it convenient and simple to use.
