[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3As shown, a bending-resistant cable includes a cable body 1, which includes a core 11, an insulating layer 12, a waterproof layer 13, an anti-aging layer 14 and a wear-resistant layer 15. The number of cores 11 is four, and the insulating layer 12 is wrapped around the surface of the core 11. The waterproof layer 13 is arranged on the side of the insulating layer 12 away from the core 11, the anti-aging layer 14 is arranged on the other side of the waterproof layer 13 away from the insulating layer 12, and the wear-resistant layer 15 is arranged on the other side of the anti-aging layer 14 away from the waterproof layer 13. The material of the wear-resistant layer 15 is cross-linked polyethylene, and the material of the anti-aging layer 14 is polyvinyl chloride. By arranging the wear-resistant layer 15 and the anti-aging layer 14, the toughness and anti-aging performance of the cable body 1 can be improved, and the phenomenon of cracks on the surface of the cable body 1 when bending can be effectively prevented. A plurality of wear-resistant ridges 4 are arranged on the side of the wear-resistant layer 15 away from the anti-aging layer 14, and the wear-resistant ridges 4 are equidistantly surrounded. The surface of the wear-resistant layer 15 can be protected by the setting of wear-resistant ridges 4 to prevent it from directly contacting the ground, thereby extending its service life. Several wear-resistant blocks 2 are fixed on the front and back of both sides of the surface of the cable body 1, and elastic parts 3 are fixed between the left and right wear-resistant blocks 2 and the wear-resistant blocks 2. By setting the wear-resistant layer 15 and the anti-aging layer 14, the toughness and anti-aging performance of the cable body 1 can be improved, and the phenomenon of cracks on the surface of the cable body 1 when bending can be effectively prevented. At the same time, it can also prevent moisture from entering the interior of the cable body 1, further improving the protection effect. By setting the wear-resistant blocks 2 and the elastic parts 3, when the cable body 1 is bent, the elastic force of the elastic parts 3 itself can be used to conveniently drive the cable body 1 back to the starting position, thereby effectively reducing the number of bending times of the cable body 1 and thus extending its service life.

[0019] Several support frames 5 are provided on the surface of the wire core 11, and the grooves on the inner side of the support frames 5 fit with the surface of the wire core 11. Through the setting of the support frames 5, the wire core 11 can be limited and supported, thereby protecting it. The wear-resistant block 2 is made of rubber, and the elastic member 3 is made of spring steel. Through the setting of the wear-resistant block 2 as rubber material, when the cable body 1 is dragged, the wear-resistant block 2 will first contact the ground, thereby facilitating the protection of the surface of the cable body 1. When the cable body 1 is bent, the elastic member 3 can be set as spring steel so that it can drive the cable body 1 back to the starting position through its own elastic force to prevent the cable body 1 from bending. The number of support frames 5 is the same as the number of rows of wear-resistant blocks 2, and the positions of the support frames 5 and the wear-resistant blocks 2 correspond one to one. Such a design can not only effectively protect the wire core 11, but also prevent it from being broken.

[0020] Working principle: During use, when the cable body 1 bends during the dragging process, the elastic force of the elastic part 3 itself can be used to conveniently drive the cable body 1 back to the starting position to avoid bending. When the cable body 1 is in use, the wear-resistant ridges 4 and the wear-resistant blocks 2 can be set to have a wear-resistant effect on the surface of the cable body 1. At the same time, the wear-resistant layer 15 and the anti-aging layer 14 can improve the toughness and anti-aging performance of the cable body 1, and effectively prevent cracks from appearing on the surface of the cable body 1. At the same time, the waterproof layer 13 can prevent the internal wires from being eroded by rainwater, causing unnecessary losses.
