The insulating rubber inner layer 302 and the insulating rubber outer layer 303 are respectively provided on both sides of the metal mesh plate 301. A plurality of ventilation holes 304 are equidistantly provided on the insulating rubber inner layer 302 and the insulating rubber outer layer 303. A heat barrier layer 4 is provided outside the fiberglass layer 1. By using the heat insulation layer 3 and the heat barrier layer 4 in combination, the pipe body has the functions of heat insulation and heat protection during use, improving the practicality of use. And a protective layer 5 is provided outside the heat barrier layer 4. Through the protective layer 5, the service life of the pipe body is further improved, and the protection time of the pipe body for the wire is extended. Meanwhile, installation side plates 6 are symmetrically provided on both sides of the protective layer 5.

[0025] Specifically, the reinforcement support layer 2 includes a housing 201 and a positioning ring seat 202. The housing 201 is made of metal. Meanwhile, positioning ring seats 202 are symmetrically provided at both ends of the housing 201. The inner diameter dimension of the housing 201 is the same as the inner diameter dimension of the positioning ring seat 202. A plurality of reinforcing rods 203 are equidistantly installed inside the housing 201. Meanwhile, a plurality of rubber positioning columns 204 are equidistantly provided between adjacent reinforcing rods 203. By using the reinforcing rods 203 and the rubber positioning columns 204 in combination, the strength of the housing 201 during use is improved, thereby further improving the overall strength of the pipe body and avoiding damage to the internal wire caused by external force extrusion.

[0026] Further explanation, the outer diameter dimension of the positioning ring seat 202 is the same as the inner diameter dimension of the protective layer 5. The outer side of the positioning ring seat 202 is attached to the inner side of the first sealing piece 7.
