A movable groove is provided on the inner side of the sliding block 203 at the corresponding position of the clamping screw 205.

A fixing piece 206 is slidably installed on the top of the top mounting plate 201. A clamping nut 207 is threadedly connected to the outer side of the clamping screw 205.
[0032] A limiting groove 208 is provided on one end face of the sliding block 203. An anti-slip plate 209 is rotatably installed on the inner side of the limiting groove 208. A connecting rod 210 is welded to one end of the anti-slip plate 209. An angle groove is provided at the corresponding position of the connecting rod 210 and the sliding block 203. The contact surfaces of the connecting rod 210 and the sliding block 203 are both smooth curved surfaces, which facilitates the adjustment of the angle iron 211.

Copper pieces 213 are installed at both ends of the sealing housing 1.
[0033] A heat dissipation component 3 is welded to the top of the mounting plate 201;
[0034] The heat dissipation component 3 includes an outwardly expanding air guide 301, a side air guide plate 302, a heat dissipation fin 303, a ventilation chamber 304, a heat insulation groove plate 305, and heat insulation rubber 306;

Two sets of outward-expanding air guide 301 are provided, and the two sets of outward-expanding air guide 301 are symmetrically installed on the top of the mounting plate 201. The two sets of outward-expanding air guide 301 are connected by a side air guide plate 302 to facilitate air circulation. A side air guide plate 302 is welded to one end face of the outward-expanding air guide 301. A heat sink 303 is welded to the top of the mounting plate 201. A ventilation chamber 304 is formed between the heat sink 303 and the side air guide plate 302. A heat insulation groove plate 305 is welded to the top of the heat sink 303.

[0036] The working principle and usage process of this utility model are as follows: When installing the busbar trunking, the operator loosens the two clamping nuts 207, thereby releasing the clamping restriction of the fixing plate 206 and the washer 204. At this time, the clamping screw 205 can slide inside the sliding groove 202. Then, the sliding block 203 is slid to the position of the lifting frame. At this time, the connecting angle iron 211 can be rotated on the outside of the connecting rod 210 to connect the hanger to the connecting angle iron 211. The sealing housing 1 is rotated to a position with a suitable slope to the top hanger. Then, the two... The clamping nut 207 is tightened again, thereby clamping and fixing the sliding block 203 through the fixing plate 206 and the washer 204. By sliding the sliding block 203, the sliding block 203 can be quickly slid to the installation position of the hanger, select the optimal stress point of the sealing housing 1, and then quickly connect the hanger to the connecting angle iron 211. Then the angle of the sealing housing 1 can be rotated and adjusted to adapt to different roof slopes without having to re-weld a new fixing structure. This simplifies the installation steps while ensuring installation flexibility and further improves installation and usage efficiency.
[0037] Finally, a large amount of heat is generated during the use of the busbar trunking. At this time, the external air will be guided by the outward expansion air guide 301 and the side air guide plate 302 to the interior of the ventilation chamber 304. At this time, the heat sink 303 can dissipate heat quickly, and the heat generated by the copper sheet 213 can be quickly dissipated, ensuring heat dissipation efficiency so that the busbar trunking can be used stably. When an external fire occurs, the fire will first burn the heat insulation plate 305. At this time, the heat can be quickly dissipated by the heat insulation rubber 306, and the heat insulation plate 305 can also dissipate heat quickly through the heat sink 303, preventing the heat insulation plate 305 from deforming, thereby ensuring the structural stability of the sealing shell 1, and preventing the deformed sealing shell 1 from squeezing the internal copper sheet 213, improving the fire resistance of the busbar trunking and improving the stability of the busbar trunking in use.
