Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: An end head for a busbar trunking, including a first busbar trunking 1, a second busbar trunking 2 and a connector 3. A second busbar trunking 2 is provided on the right side of the first busbar trunking 1, and a connector 3 is provided at the connection between the second busbar trunking 2 and the first busbar trunking 1. The end head for the busbar trunking further includes: an adjusting mechanism 4 provided at the top of the connection between the first busbar trunking 1 and the second busbar trunking 2, and a connecting mechanism 5 provided on both sides of the adjusting mechanism 4. Among them, the adjusting mechanism 4 can adjust the opening position of the connecting mechanism 5 to facilitate connection with the first busbar trunking 1 and the second busbar trunking 2.

[0020] Specifically, the adjusting mechanism 4 includes: a horizontal plate 401, a groove block 402, a stud 403, a first bevel gear 404 and a second bevel gear 405;

[0021] The horizontal plate 401 is provided outside the connection between the first busbar trunking 1 and the second busbar trunking 2. The groove block 402 is fixedly provided at the top of the horizontal plate 401. The groove block 402 is used to support the stud 403. The stud 403 is rotatably provided inside the groove block 402. When the stud 403 rotates, it can push the groove plate 502 outward. The first bevel gear 404 is fixedly provided on the outer wall of the stud 403. The second bevel gear 405 is rotatably provided inside the top of the groove block 402, and the bottom end of the second bevel gear 405 is meshed with the first bevel gear 404. Among them, when the second bevel gear 405 rotates, it can drive the stud 403 to rotate simultaneously through the first bevel gear 404. A cavity is provided inside the groove block 402, and a diamond-shaped groove is provided inside the outer side of the second bevel gear 405.

[0022] More specifically, the connecting mechanism 5 includes: a connecting plate 501, a groove plate 502, a bolt 503, and a protective plate 504;

[0023] The connecting plate 501 is threadedly arranged on both outer sides of the outer wall of the double-headed stud 403. The groove plate 502 is sleeved on both outer walls of the cross plate 401, and the top end of the groove plate 502 is connected to the bottom end of the connecting plate 501. When the groove plate 502 moves outward, it is convenient to align with the position of the reserved hole. The bolt 503 is inserted into both sides of the groove plate 502. The protective plate 504 is fixedly arranged on both sides of the cross plate 401. Among them, when the connecting plate 501 moves outward, it can drive the groove plate 502 to move outward simultaneously to adjust the position of the reserved hole. A threaded hole is opened inside the connecting plate 501, and a reserved hole is opened at the top end of the groove plate 502 for fixing on the outer wall of the bus duct through the bolt 503.

[0024] Working principle: When the end head for the bus duct starts to be used, the user first connects the first bus duct 1 and the second bus duct 2 through the connector 3. Then the user places the groove plate 502 on the outer walls of the first bus duct 1 and the second bus duct 2. Then the user inserts a tool into the inside of the second bevel gear 405 to rotate it. When the second bevel gear 405 rotates, it can drive the double-headed stud 403 to rotate simultaneously inside the groove block 402 through the first bevel gear 404. When the double-headed stud 403 rotates, it can drive the groove plate 502 to move outward simultaneously while fitting the outer walls of the first bus duct 1 and the second bus duct 2 to align the position of the reserved hole. Then when the position of the reserved hole is aligned, the user stops rotating the second bevel gear 405 and pulls out the tool from the inside of the second bevel gear 405. The user inserts and rotates the bolt 503 to fix the groove plate 502 on the outer walls of the first bus duct 1 and the second bus duct 2. After the fixing is completed, the protective plate 504 can effectively protect the connection position of the first bus duct 1 and the second bus duct 2.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
