In the following detailed description, for the convenience of explanation, many specific details are elaborated to provide a comprehensive understanding of the embodiments of the present utility model. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0027] As Figures 1-5 shown, a low-ecentricity low-voltage power cable includes an insulating outer sheath 1. A convenient dragging mechanism 2 is provided on the outer wall of the insulating outer sheath 1. The convenient dragging mechanism 2 includes a splicing sleeve one 21 and a splicing sleeve two 22. The splicing sleeve one 21 is movably connected to the bottom of the insulating outer sheath 1, and the splicing sleeve two 22 is movably connected to the top of the insulating outer sheath 1. The adjacent sides of the splicing sleeve one 21 and the splicing sleeve two 22 are detachably connected. A receiving block 211 is fixedly installed at the bottom of the splicing sleeve one 21. A rotating seat 212 is rotatably connected to the bottom of the receiving block 211. An alloy bent rod 213 is welded to the bottom of the rotating seat 212. One end of the alloy bent rod 213 away from the rotating seat 212 is rotatably connected to a support roller 214. The splicing sleeve one 21 and the splicing sleeve two 22 are detachably installed on the outer surface of the insulating outer sheath 1 to complete the fixing process of the receiving block 211. At the same time, the insulating outer sheath 1 is in contact with the ground through the support roller 214. During the process of dragging the insulating outer sheath 1, the support roller 214 can roll on the ground, reducing the consumption of manpower and avoiding the problem of wear of the insulating outer sheath 1. The entire support roller 214 can be disassembled after the insulating outer sheath 1 is moved in place, facilitating the laying of the insulating outer sheath 1. Through the design of the rotating connection between the receiving block 211 and the rotating seat 212, the support roller 214 can rotate towards the dragging direction of the insulating outer sheath 1, further reducing the consumption of manpower.

[0028] In this embodiment, an extension strip one 23 is fixedly installed on the outer wall of the splicing sleeve one 21, and an extension strip two 24 is fixedly installed on the outer wall of the splicing sleeve two 22. A fitting groove 25 is opened at the top of the extension strip two 24. A chute plug 26 is fixedly installed at the top of the extension strip one 23. The chute plug 26 is movably inserted into the inner cavity of the fitting groove 25. A sliding limit block 27 is slidably connected to the inner wall of the chute plug 26. A folding rod 28 is fixedly installed at the top of the sliding limit block 27. A magnetic attraction block 29 is fixedly installed at one end of the folding rod 28 away from the sliding limit block 27. When installing the splicing sleeve one 21 and the splicing sleeve two 22, insert the chute plug 26 into the inside of the fitting groove 25, and then slide the folding rod 28 inside the sliding limit block 27 to make the two magnetic attraction blocks 29 on the same side magnetically attract each other to complete the positioning of the sliding limit block 27. At the same time, the extension strip two 24 is limited by the sliding limit block 27, that is, the installation of the splicing sleeve one 21 and the splicing sleeve two 22 is completed. On the contrary, the splicing sleeve one 21 and the splicing sleeve two 22 can be disassembled.

[0029] In this embodiment, a copper wire braided layer 11 is fixedly connected to the inner wall of the insulating jacket 1. A soft plastic film layer 12 is fixedly connected to the inner wall of the copper wire braided layer 11. The thickness value of the soft plastic film layer 12 is set to 1.5 mm. A tungsten alloy film layer 13 is fixedly connected to the inner wall of the soft plastic film layer 12. A glass fiber filling layer 14 is filled in the inner cavity of the tungsten alloy film layer 13. A polyurethane protective sleeve 15 is arranged inside the glass fiber filling layer 14. A first silicone rubber protective sleeve 16 is fixedly connected to the inner wall of the polyurethane protective sleeve 15. A second silicone rubber protective sleeve 17 is fixedly connected to the inner wall of the first silicone rubber protective sleeve 16. A conductor 18 is fixedly connected to the inner wall of the second silicone rubber protective sleeve 17. The conductor 18 is double-wrapped by the first silicone rubber protective sleeve 16 and the second silicone rubber protective sleeve 17 to reduce the eccentricity of the conductor 18 and avoid the problem that this structure is easily punctured. Through the cooperation of the copper wire braided layer 11 and the tungsten alloy film layer 13, electromagnetic waves can be shielded to achieve the function of anti-interference. Through the design of the soft plastic film layer 12, the problem that the copper wire braided layer 11 and the tungsten alloy film layer 13 are damaged due to mutual friction is avoided.

[0030] The working principle of a low-voltage power cable with low eccentricity of the present utility model is as follows: The conductor 18 is double-wrapped by the first silicone rubber protective sleeve 16 and the second silicone rubber protective sleeve 17, which can reduce the eccentricity of the conductor 18. Before dragging the insulating jacket 1, the splicing sleeve one 21 and the splicing sleeve two 22 are spliced on the outer surface of the insulating jacket 1 first, so that the sliding groove insert block 26 is inserted into the inside of the fitting groove 25. Then, the folding rod 28 is slid inside the sliding limit block 27, so that the two magnetic attraction blocks 29 on the same side are magnetically attracted. During the process of dragging the insulating jacket 1, the support roller 214 can roll on the ground to achieve the function of labor-saving dragging.

[0031] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
