All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention relates to a busbar trunking with adjustable height after installation, comprising a busbar trunking body 1, a mounting frame 2 disposed on the top of the busbar trunking body 1, a fixing mounting hole 3 through each of the four corners of the mounting frame 2, four positioning brackets 4 symmetrically fixedly mounted on the bottom of the mounting frame 2, and the busbar trunking body 1 located between the bottom ends of the four positioning brackets 4, a sliding connection groove 5 through each of the four positioning brackets 4, an adjustment component 6 fixedly mounted on the bottom center of the mounting frame 2, and the bottom of the adjustment component 6 fixedly connected to the top of the busbar trunking body 1;

[0020] The adjusting assembly 6 includes a strip frame 7 with an open bottom. The strip frame 7 is fixedly installed at the bottom center of the mounting bracket 2. An adjusting block 8 is provided on one side of the strip frame 7. A bidirectional screw 9 is rotatably installed inside the strip frame 7, with one end of the bidirectional screw 9 movably passing through one side of the strip frame 7 and fixedly connected to the adjusting block 8. A positioning screw 16 is movably installed on the side of the strip frame 7 away from the adjusting block 8, with one end of the positioning screw 16 fixedly connected to the end of the bidirectional screw 9 away from the adjusting block 8. A locking nut 17 is threaded onto the outer side of the positioning screw 16, and the locking nut 17 contacts the side of the strip frame 7 away from the adjusting block 8. A circular stop 18 is fixedly installed on the end of the positioning screw 16 away from the bidirectional screw 9, and the diameter of the circular stop 18 is larger than the inner diameter of the locking nut 17. The inside of the strip frame 7 and the positioning nut 8 are fixedly installed on the side away from the adjusting block 8. A threaded movable sleeve 10 is symmetrically threaded on the outer side of the bidirectional screw 9. A positioning slider 19 is symmetrically fixedly installed on the outer side of the threaded movable sleeve 10. A positioning groove 20 is symmetrically opened through the outer side of the strip frame 7, and the positioning slider 19 is slidably installed through the inside of the positioning groove 20. A first connecting shaft 11 is fixedly installed at the bottom of the threaded movable sleeve 10. A movable connecting strip 12 is rotatably installed on the first connecting shaft 11. A second connecting shaft 13 is rotatably installed at the end of the movable connecting strip 12 away from the first connecting shaft 11. A movable connecting bracket 14 is fixedly installed at the bottom of the second connecting shaft 13. The two movable connecting brackets 14 are symmetrically fixedly installed on the top of the busbar trunking body 1. A sliding connecting block 15 is fixedly installed on the side of the movable connecting bracket 14 near the positioning bracket 4, and the sliding connecting block 15 is slidably installed through the inside of the sliding connecting groove 5.

[0021] During use, the interaction of the busbar trunking body 1, mounting bracket 2, fixed mounting hole 3, positioning bracket 4, sliding connection groove 5, and adjustment component 6 allows the busbar trunking to be easily adjusted in height as needed after hoisting and fixing, reducing its limitations and making it easier for operators to operate, thus achieving better practicality. Furthermore, the interaction of the positioning slider 19 and positioning groove 20 ensures better stability when the threaded movable sleeve 10 moves, thereby ensuring that the adjustment component 6 can work stably.

[0022] Working principle: During operation, the mounting bracket 2 is first fixedly installed using fixing bolts that match the diameter of the fixing mounting hole 3. Then, the adjusting block 8 is held to keep the bidirectional screw 9 stationary, thereby keeping the positioning screw 16 stationary. The locking nut 17 is then loosened to release the positioning screw 16, thus releasing the positioning of the bidirectional screw 9. The adjusting block 8 is then rotated, causing the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the threaded movable sleeve 10 to move. The threaded movable sleeve 10 drives the positioning slider 19 to slide inside the positioning groove 20, ensuring better stability during movement. Simultaneously, the threaded movable sleeve 10 drives the first connecting shaft 11 to move, the first connecting shaft 11 drives the movable connecting bar 12 to move, and the movable connecting bar 12 drives the second connecting shaft 13 to move. The connecting shaft 13 drives the movable connecting frame 14 to move upward. The movable connecting frame 14 drives the sliding connecting block 15 to slide inside the sliding connecting groove 5 inside the positioning bracket 4, which can ensure better stability of the movable connecting frame 14 during movement. At the same time, the movable connecting frame 14 drives the busbar trunking body 1 to move upward. After the busbar trunking body 1 moves to the required height, stop rotating the adjusting block 8, and then hold the adjusting block 8 again to keep the bidirectional screw 9 stationary. Then tighten the locking nut 17 to reposition the bidirectional screw 9, completing the height adjustment operation of the busbar trunking body 1 after it is fixed. This allows the busbar trunking to be easily adjusted in height as needed after hoisting and fixing during use, reducing its limitations and making it easier for workers to operate, thus achieving better practicality.
