[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 10 As shown, this embodiment proposes a cable with anti-wear function, including a conductor 1 and an insulating layer 2, wherein the conductor 1 and the insulating layer 2 are both provided with a plurality of insulating layers 2, and the insulating layer 2 corresponds to the conductor 1 one by one, and the insulating layer 2 is wrapped around the outside of the conductor 1, and further includes an inner lining layer 3, an armor layer 4, an outer protective layer 5 and an outer protective mechanism. Compared with the existing cables, the strength and rigidity of the inner and outer sides of the cable are strengthened by the reinforcing core 6 and the armor layer 4, and the tensile and bending resistance of the cable is improved. The arc frame and the protective frame are located on the outside of the cable, and the outer side of the cable can be protected from wear. At the same time, the movement of the cable is reduced by the rotation of the ball 202. The resistance during the movement can further improve the cable's wear resistance. Between two adjacent outer protective mechanisms, the protective sheet 303 is pulled by the pulling frame 401 to make the pulling frame 401 contact with the adjacent arc frame. The pulling frame 401 and the arc frame are connected by the limiting rod 402 and the locking plate 403. At the same time, the protective sheet 303 is in a tensioned state under the action of the coil spring 304, so as to provide wear resistance for the cable between the two adjacent outer protective mechanisms, enhance the stability between the two outer protective mechanisms, avoid the movement and falling off of the outer protective mechanisms, and the cable has a strong wear resistance.

[0018] like Figure 1 to Figure 2As shown, the inner lining layer 3 is located outside the multiple insulating layers 2, and a filler is arranged between the inner lining layer 3 and the insulating layer 2. The armor layer 4 is wrapped outside the inner lining layer 3, and the outer protective layer 5 is arranged outside the armor layer 4. The insulating layer 2 and the filler provide insulation protection for the multiple conductors 1. At the same time, the roundness and strength of the cable are ensured by the filler. The inner lining layer 3 wraps the filler and the multiple conductors 1 to ensure the stability of the cable. In order to further improve the strength of the cable, it also includes a reinforcing core 6. The reinforcing core 6 is arranged at the center of the armor layer 4, and the multiple conductors 1 are located on the outside of the reinforcing core 6. The reinforcing core 6 is made of metal, which can enhance the tensile strength and bending strength at the center position of the cable, thereby further improving the service life of the cable.

[0019] like Figures 3 to 10 As shown, multiple external protection mechanisms are provided for protecting the outside of the external protection layer 5. The external protection mechanism includes an arc frame and a protection frame. Two arc frames are provided, and the two arc frames are detachably connected. The arc frame includes two arc bars 101, and multiple protection rods 102 are provided between the two arc bars 101. Connecting plates 103 are provided on both sides of the two arc bars 101. Sub-Velcro 104 and mother Velcro 105 are provided on the two connecting plates 103 respectively. The inner side of the arc frame contacts the outer side of the external protection layer 5. An anti-slip strip 106 is provided on the inner side of the arc frame, and the anti-slip strip 106 contacts the external protection layer 5. Through the cooperation of the sub-Velcro 104 and the mother Velcro 105, the two arc frames can be wrapped around the outside of the external protection layer 5, and can be adapted to In response to the diameter change of the cable within a certain range, the stability of the arc frame can be ensured by the anti-slip strip 106. Two protective frames are provided, and the protective frames correspond to the arc frame one by one. The protective frame is arranged on one side of the arc frame through a connecting rod. The inner side of the protective frame contacts the outer side of the outer protective layer 5. The protective frame includes a plurality of arch blocks 201. The outer side of the arch block 201 is higher than the outer side of the arc frame. The outer side of the arch block 201 is rotatably provided with a plurality of balls 202. During the transportation or laying of the cable, the outer side of the arch block 201 first contacts the ground or other objects, reducing the contact between the outer protective layer 5 and the outside, thereby reducing the wear of the cable itself. At the same time, the rotation of the balls 202 can reduce the resistance of the cable when it moves, further reducing the wear of the cable and the protective frame.

[0020] like Figures 3 to 10As shown, in order to improve the stability of the protective frame, a connecting block 7 is provided at one end of the protective frame, and a connecting seat 8 is provided at the other end of the protective frame. A plug rod 9 is provided on the connecting block 7, and a slot matching the plug rod 9 is opened on the connecting seat 8. A magnet 10 is provided inside the slot. The material of the plug rod 9 is iron metal. The two protective frames are mounted on the outside of the outer protective layer 5, and the plug rod 9 on one protective frame is inserted into the inside of the slot on the other protective frame. The stability of the plug rod 9 is ensured by the mutual attraction of the magnet 10 and the plug rod 9, thereby ensuring the stability of the connection between the two protective frames. Then, the two arc frames are connected by the mutual attachment of the sub-Velcro 104 and the mother Velcro 105, so that the arc frame and the protective frame are installed on the outside of the outer protective layer 5 to ensure the stability of the arc frame and the protective frame. At the same time, the outer protective layer 5 of the cable is protected by the arc frame and the protective frame.

[0021] like Figures 3 to 10As shown, in order to provide more comprehensive protection for the outside of the cable, an auxiliary protective member is also included, and the auxiliary protective member is used to provide auxiliary protection for the outside of the outer protective layer 5. The auxiliary protective member includes a support seat 301, a reel 302, a protective sheet 303 and a connecting member. The support seat 301 is arranged on the inner side of the arch block 201, and the support seat 301 is in contact with the outer side of the outer protective layer 5. The inner side of the arch block 201 is filled to a certain extent by the support seat 301. When the arch block 201 is in contact with the outside, the support seat 301 and the two end points of the arch block 201 close to the cable are pressed together on the surface of the outer protective layer 5 of the cable, and the contact area with the outer protective layer 5 is increased by the support seat 301, thereby reducing the pressure at each contact position, avoiding the outer protective layer 5 The same position is squeezed for a long time and is damaged. A winding chamber is provided inside the support seat 301, and the reel 302 is rotatably arranged inside the winding chamber. The protective sheet 303 is wound around the outside of the reel 302 through a coil spring 304. A through hole is provided on the support seat 301 for the protective sheet 303 to extend out. The connecting piece is used to connect the protective sheet 303 and an arc frame in another adjacent external protective mechanism. The connecting piece includes a pulling frame 401, a limiting rod 402 and a locking plate 403. The pulling frame 401 is arranged on one side of multiple protective sheets 303 away from the reel 302. Two pulling frames 401 are also provided. The pulling frames 401 correspond to the arc frames and the protective frames one by one. The pulling frame 401 is connected to multiple protective sheets 303 on the corresponding protective frames. The positioning rod 402 is arranged on the side of the arc frame away from the protective frame, the pulling frame 401 is provided with a limiting hole matching the limiting rod 402, the limiting rod 402 is provided with a locking hole, the locking plate 403 is slidably arranged inside the locking hole, the locking plate 403 is in contact with the side of the pulling frame 401 away from the arc frame, and multiple protective plates 303 on a protective frame can be pulled simultaneously through the pulling frame 401. When the pulling frame 401 contacts the adjacent arc frame, the limiting rod 402 passes through the limiting hole, and the locking plate 403 is inserted into the locking hole, so that the pulling frame 401 and the arc frame can be connected. There is a certain sliding damping between the locking plate 403 and the locking hole, which can ensure the stability of the connection between the pulling frame 401 and the arc frame. At the same time, when the coil spring is Under the action of 304, the protective sheet 303 is in a tensioned state, the pulling frame 401 and the locking plate 403 are in close contact and restrain each other, further improving the connection stability between the pulling frame 401 and the arc frame. At the same time, the protective sheet 303 is in a tensioned state, which can protect the cables between the two adjacent external protection mechanisms, further reducing the contact between the outer protective layer 5 of the cable and the outside world. At the same time, the protective sheet 303 is a metal sheet with a certain elasticity, similar to a tape measure, which can bend the cable to a certain extent, and pull the locking plate 403 out of the locking hole. Under the action of the winding spring 304, the protective sheet 303 is retracted to the outside of the reel 302, thereby driving the pulling frame 401 to return to its original position, that is, the position close to the support seat 301 and the protective frame.

[0022] The working principle or use process of the cable with anti-wear function is as follows: Clamp the two protective frames on the outside of the outer protective layer 5 of the cable, insert the insertion rod 9 into the inside of the slot, and then fit the sub-velcro 104 and the mother Velcro 105 to tightly connect the arc frame to the outside of the outer protective layer 5, select a suitable length position, and install another outer protective mechanism on the outside of the outer protective layer 5 of the cable in the same way, and at the same time, tightly fit the pulling frame 401 with the previous arc frame, insert the limiting rod 402 into the inside of the limiting hole, and insert the locking plate 403 into the inside of the locking hole, connect the pulling frame 401 with the arc frame, and install multiple outer protective mechanisms on the outside of the outer protective layer 5 of the cable in the above manner; The outer protective layer 5 of the cable is protected by the arc frame and the protective frame, and the gap between two adjacent outer protective mechanisms is protected by the protective sheet 303, thereby reducing the contact between the outer protective layer 5 of the cable and the outside world, thereby reducing the wear of the outer protective layer 5, and at the same time, the rotation of the ball 202 reduces the resistance of the cable during movement, further reducing the wear of the cable.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
