[0013] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0014] like Figure 1 As shown, a wear-resistant and corrosion-resistant network cable includes a cross skeleton 1, a wire core 2 is arranged around the cross skeleton 1, the wire core 2 is a twisted pair wire, the outer side of the wire core 2 is wrapped with aluminum foil, and the aluminum foil is used to improve the shielding performance. The wire core 2 is fixed to the cross skeleton 1 by a braided belt 3, and a corrosion-resistant layer 4 is arranged on the outside of the wire core 2. The corrosion-resistant layer 4 is sleeved on the cross skeleton 1. In this embodiment, the corrosion-resistant layer 4 is made of polyethylene material. The polyethylene material has good chemical stability and can withstand the corrosion of most acids and alkalis.

[0015] The corrosion-resistant layer 4 is provided with a sheath 5 on the outside, the sheath 5 is sleeved on the corrosion-resistant layer 4, the sheath 5 is evenly distributed with four supporting protrusions 6 around it, and the surface of the supporting protrusions 6 is evenly distributed with balls 7, and the balls 7 roll on the surface of the supporting protrusions 6. In this embodiment, the sheath 5 and the balls 7 are made of nylon, which itself has good wear resistance and can improve the wear resistance of the network line.

[0016] The support protrusion 6 is located at the supporting position of the cross frame 1, and the supporting end of the cross frame 1 is connected with an arc-shaped support baffle 8. The arc-shaped support baffle 8 is used to support the support protrusion 6 to prevent it from being concave, thereby reducing the wear on the surface of the network line by replacing sliding friction with rolling friction.

[0017] Support feet 9 are symmetrically arranged on both sides of the ball 7 on the surface of the sheath 5. The support feet 9 are located in the middle of two adjacent balls. The support feet 9 have the function of stabilizing the network line to prevent the network line from rotating and ensure that the balls 7 between the support feet 9 are in contact with the ground and roll.
