[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following is combined with Figure 1-5 To further explain this application in detail,

[0023] The present application embodiment discloses a bending-resistant cable. Figures 1 to 5 A bending-resistant cable comprises a conductor 1, a tensile layer 2 is laminated on the surface of the conductor 1, an insulating layer 3 is laminated on the surface of the tensile layer 2, a guide layer 4 is laminated on the surface of the insulating layer 3, a shielding layer 5 is laminated on the surface of the guide layer 4, a filling layer 6 is laminated on the surface of the shielding layer 5, a protective layer 7 is laminated on the surface of the filling layer 6, a cold-resistant layer 8 is laminated on the surface of the protective layer 7, and a wear-resistant layer 9 is laminated on the surface of the cold-resistant layer 8;

[0024] Reference Figure 2 and Figure 3 The tensile layer 2 is made of nylon rope, and the insulating layer 3 is made of rubber. The tensile layer 2 made of nylon rope can prevent the cable from being bent to a certain angle, thereby avoiding the damage of the wire 1. The insulating layer 3 made of rubber can insulate the surface of the wire 1 to prevent leakage of the wire 1, and the tensile layer 2 and the insulating layer 3 are spiral.

[0025] Reference Figure 3 The guide layer 4 is made of silicone, and the shielding layer 5 is made of aluminum. The guide layer 4 made of silicone can achieve good softness when the cable is bent, so that the spiral conductor 1 on the inner wall of the guide layer 4 has a stretch amount, preventing the conductor 1 from being damaged due to stretching;

[0026] Reference Figure 4The filling layer 6 is made of polyester fiber, and the protective layer 7 is made of polyvinyl chloride. The filling layer 6 made of polyester fiber can provide buffer protection for the guide layer 4 and prevent the guide layer 4 from being squeezed and worn.

[0027] Reference Figure 4 The cold-resistant layer 8 is composed of vinyl acrylate copolymer, and the wear-resistant layer 9 is composed of polyethylene. The cold-resistant layer 8 made of vinyl acrylate copolymer can achieve the purpose of protecting the protective layer 7 of the inner wall when the cable is in a low-temperature environment. At the same time, the cold-resistant layer 8 is relatively soft and has the function of anti-ultraviolet. By setting the wear-resistant layer 9 made of polyethylene, the surface of the cold-resistant layer 8 can be protected to prevent the cold-resistant layer 8 from contacting the ground for a long time, causing surface wear and affecting the cold-resistant effect.

[0028] Reference Figure 1 and Figure 5 A fixing block 10 is fixedly installed on the surface of the wear-resistant layer 9, and a screw 11 is threadedly connected to the inner wall of the fixing block 10. A clamping block 12 is rotatably connected to the surface of the screw 11. The surface of the clamping block 12 is slidably connected to the inner wall of the fixing block 10. By setting the fixing block 10 and the screw 11, the purpose of fixing the wire 1 can be achieved. By turning the screw 11, the screw 11 will drive the clamping plate to clamp the wire 1, thereby preventing the wire 1 from retracting to the inner wall of the guide layer 4 during the bending process;

[0029] Reference Figure 5 The surface of the clamp block 12 is provided with grooves 13, and the number of the grooves 13 is several. By providing the grooves 13, the friction between the clamp block 12 and the wire 1 can be increased during the process of the clamp block 12 clamping the wire 1, so that the clamp block 12 can tighten the wire 1 more.

[0030] Working principle: The tensile layer 2 made of nylon rope can prevent the cable from being bent further when it is bent to a certain angle. The insulating layer 3 made of rubber can insulate the surface of the wire 1 to prevent leakage of the wire 1. The guide layer 4 made of silicone can achieve good softness when the cable is bent, so that the spiral wire 1 on the inner wall of the guide layer 4 has a certain amount of expansion and contraction to prevent the wire 1 from being damaged due to stretching. The filling layer 6 made of polyester fiber can provide buffer protection for the guide layer 4. The cold-resistant layer 8 made of vinyl acrylate copolymer can protect the protective layer 7 of the inner wall when the cable is in a low-temperature environment. By setting the wear-resistant layer 9 made of polyethylene, the surface of the cold-resistant layer 8 can be protected to prevent the surface of the cold-resistant layer 8 from being worn and affecting the cold-resistant effect. By setting the fixing block 10 and the screw 11, the guide can be fixed. When the cable needs to be replaced, it is only necessary to loosen the screw 11, then pull out the old wire 1, and then insert the new wire 1 into the inner wall of the guide layer 4, so as to achieve the purpose of replacing the wire 1 and avoid the phenomenon of removing and replacing the entire cable.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
