Busbar systems are efficient power distribution devices for transmitting current, and are especially suitable for power transmission in high-rise buildings and large-scale factories.

[0003] Traditional refractory cast iron busbar covers are usually one-piece designs and are large in size, making installation cumbersome. Therefore, when maintenance and repair of the internal circuits of the busbar are required, the entire cover needs to be disassembled, which is very cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] In view of the problems existing in the above-mentioned refractory castable busbar trunking, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a refractory castable busbar trunking, which solves the problem that the top cover of the existing refractory castable busbar trunking is usually an integrated design, which is large in size and cumbersome to install. Therefore, when it is necessary to maintain and repair the internal circuit of the busbar trunking, the entire top cover needs to be disassembled, which is very cumbersome, time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A refractory castable busbar trunking includes a trunking body and copper busbars. Multiple copper busbars are respectively disposed on both sides of the trunking body. A strip-shaped opening is formed at the top of the trunking body. A folding plate is disposed on the inner side of the strip-shaped opening. Strip-shaped grooves are formed on both sides of the strip-shaped opening. Both sides of the folding plate extend to the inner side of the corresponding strip-shaped groove. A maintenance ring is fixedly fitted at the middle end of the folding plate. Both ends of the maintenance ring are fixedly connected to the inner wall of the corresponding trunking body.

Insertion holes are provided on both sides of the sealing cover. The outer end of the U-shaped rod is inserted into the corresponding insertion hole.

[0009] Preferably, the second limiting mechanism includes a plug rod and a limiting tube. A side plate is fixedly provided on the rear side of the inspection ring. A through hole is opened at the end of the side plate away from the inspection ring. The plug rod is movably sleeved inside the through hole. Multiple limiting tubes are fixedly provided from left to right on the upper surface of the junction box body near the plug rod. One end of the plug rod is inserted into the corresponding limiting tube.

[0010] Preferably, a first spring is fixedly installed on the side of the stop block near the U-shaped rod, and the other end of the first spring is fixedly connected to the inner wall of the fixed shell.

[0011] Preferably, both the through hole and the insertion rod have rectangular cross-sections.

[0012] Preferably, a fixing ring is fixedly sleeved at the lower end of the insertion rod, and a second spring is movably sleeved on the rod wall of the insertion rod, with the two ends of the second spring being fixedly connected to the corresponding side plate and the fixing ring, respectively.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] This invention allows for easy and time-saving operation by pulling the insertion rod to separate it from the limiting tube, thus releasing the limiting effect on the inspection ring. The inspection ring can then be pulled to the desired inspection position. Next, pulling the two U-shaped rods away from the inspection ring releases one end of the U-shaped rod from the corresponding insertion hole, thereby releasing the limiting effect on the sealing cover and separating it from the inspection ring. This opens the inspection ring, allowing for easy access to the internal wiring of the cable tray for repair. Attached Figure Description
