[0002] Copper bars play a crucial role in power transmission and distribution systems. In power systems, the transmission of large currents relies on efficient and stable conductive materials, and copper bars are the ideal choice to meet this demand. It can not only effectively reduce energy loss and improve the efficiency of power transmission, but also ensure the stable operation of the system. At the connection position of wire lines in power control boxes, copper bars are required for assembly. However, there are misalignments or inconsistencies in the directions of the connection positions. Therefore, the copper bars need to be bent to effectively conform to the assembly at the connection positions. Patent No. CN218123012U provides a copper bar with multi-structure adjustment, which is provided with a first copper bar and a second straight-tooth gear for easy connection, and the right end inner side of the outer surface of the first copper bar is rotatably connected with a third copper bar; including: a limit strip, fixedly installed on the lower side of the left end of the outer surface of the first copper bar, and a card slot is arranged on the inner surface of the first copper bar, and a card block is snap-connected to the inner surface of the card slot. At the same time, the upper surface end of the card block is installed with a second copper bar, which is convenient for the second copper bar to be snap-connected with the first copper bar, and bolts for tightening the threads are connected to the inner surfaces of the second copper bar and the first copper bar. This multi-structure-adjustable copper bar is provided with a first copper bar and a second copper bar that are convenient for assembly, and with the use of bolts and limit strips, the first copper bar and the second copper bar of different lengths can be replaced to adjust the lengths of the first copper bar and the second copper bar used, preventing them from falling off.

[0003] The adjustment structure in the above patent is too complex, the operation is rather cumbersome, and it is not easy for mass production and assembly. The production cost is relatively high, and it is time-consuming and laborious. Therefore, improvements are needed, and a copper bar with multi-structure adjustment is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A copper bar with multi-structure adjustment, including the equipment main body, and the equipment main body includes:

[0006] A first copper bar, an extension plate is opened at the right end of the first copper bar, and a connecting rod is fixedly connected to the front end of the extension plate.

[0007] Furthermore, a collar is rotatably connected to the outside of the connecting rod, and a plurality of threaded holes are opened at the front and rear ends of the collar.

[0008] Further, a compression nut is threadedly connected to the rear end of the collar, and the compression nut penetrates through the first copper bar.

[0009] Further, a second copper bar is fixedly connected to the right end of the collar.

[0010] Further, a rectangular limiting hole is formed in the right side of the front end of the first copper bar, and a return spring is fixedly connected inside the rectangular limiting hole.

[0011] Further, one end of the return spring is fixedly connected to a limiting block. An arc surface is formed at the front end of the limiting block, and the limiting block slides left and right inside the rectangular limiting hole.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing an extension plate, a connecting rod, a collar, a threaded hole, and a compression nut, when it is necessary to bend the copper bar, the second copper bar is rotated upward or downward to an appropriate angle, and then the compression nut is threadedly connected to the threaded hole on the collar to fix the second copper bar. The operation is simple, effectively improving the work efficiency. By providing a rectangular limiting hole, a return spring, and a limiting block, when splicing the copper bars, the collar is sleeved from the front end of the connecting rod and moved backward to a certain position. Due to the elastic force of the return spring, the limiting block is pushed out, and the limiting block limits the collar, facilitating the extension of the length of the copper bar to prevent the second copper bar from slipping off. When disassembling, press the limiting block and move the collar outward to disassemble, which is convenient for quickly adjusting the length of the copper bar and effectively increasing the practicality of the device.
