[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1-3 As shown, a cable with an anti-pull function includes a first protective layer 1, several groups of anti-pull strips 2 are fixedly provided on the outside of the first protective layer 1, a second protective layer 3 is fixedly provided on the inside of the first protective layer 1, several groups of reinforcing wires 4 are fixedly provided on the inside of the second protective layer 3, a fiber tensile braided layer 5 is fixedly provided on the inside of the second protective layer 3, three groups of insulating layers 6 are provided on the inside of the fiber tensile braided layer 5, a cable copper core 7 is fixedly provided on the inside of the three groups of insulating layers 6, four groups of elastic reinforcing ribs 8 are provided on the inside of the fiber tensile braided layer 5 near the three groups of insulating layers 6, three groups of elastic reinforcing strips 9 are fixedly connected between the four groups of elastic reinforcing ribs 8, and an elastic filler 10 is provided on the inside of the fiber tensile braided layer 5.

[0020] In this embodiment, the first protective layer 1 and the anti-pull strip 2 are made of wear-resistant rubber material. The first protective layer 1 and several groups of anti-pull strips 2 are an integrated structure. The first protective layer 1, the second protective layer 3, and the fiber tensile braided layer 5 are fitted together. Several groups of anti-pull strips 2 are evenly arranged in a circle. The anti-pull strip 2 is semi-circular. Several groups of reinforcing wires 4 are evenly arranged in a circle. The shape of the reinforcing wire 4 is circular. The reinforcing wire 4 is a tinned flexible steel wire rope. Three groups of insulating layers 6 and the cable copper core 7 are arranged in a triangle. The elastic reinforcing ribs 8 and the elastic reinforcing strips 9 are arranged parallel to the cable copper core 7. The elastic reinforcing ribs 8 and the elastic reinforcing strips 9 are made of elastic rubber material. The elastic reinforcing ribs 8 and the elastic reinforcing strips 9 are an integrated structure.

[0021] Specifically, first, the wear-resistant and elastic materials of the first protective layer 1 and the anti-pull strip 2 make the cable corrosion-resistant, so as to avoid external wear affecting the normal operation of the cable after long-term use, causing potential dangers. The combined use of the second protective layer 3, the reinforcing wire 4, and the fiber tensile braided layer 5 increases the overall tensile resistance and firmness of the cable, and it can quickly restore to a vertical state after bending, avoiding damage or even breakage of the cable due to bending. The four groups of elastic reinforcing ribs 8, elastic fillers 10 and three groups of elastic reinforcing strips 9 around the three groups of insulating layers 6 can play an anti-tensile role on both sides of any bending part of the cable when the cable is bent, thereby preventing the insulating layer 6 and the cable copper core 7 from losing elasticity and breaking due to excessive bending, so as to achieve the purpose of the internal three groups of cable copper cores 7 having enhanced tensile strength and anti-deformation functions, meeting the use requirements of various modern mechanical devices, such as scrapers, which have high anti-tensile function requirements.

[0022] Working principle:

[0023] During use, first, due to the wear-resistant and elastic materials of the first protective layer 1 and the anti-pulling strip 2, the cable is corrosion-resistant, preventing external wear from affecting normal operation after long-term use and causing potential hazards. By using the combination of the second protective layer 3, the reinforcing wires 4, and the fiber tensile braided layer 5, the overall anti-pulling property and firmness of the cable are increased, and it can quickly return to the vertical state after being bent, avoiding damage or even breakage of the cable caused by bending. Through the cooperation of the four elastic reinforcing ribs 8, the elastic filler 10, and the three elastic reinforcing strips 9 around the three insulating layers 6, when the cable is bent, anti-pulling effects can be achieved on both sides of any bent part of the cable, thereby preventing the insulating layer 6 and the cable copper core 7 from breaking due to excessive bending and loss of elasticity, achieving the purpose that the three internal cable copper cores 7 have enhanced anti-tensile force and anti-deformation functions, meeting the usage requirements of various modern mechanical devices, such as loaders that have relatively high anti-pulling function requirements.
