Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the utility model provides a compression-resistant PVC communication pipe, which comprises a communication pipe body, wherein the communication pipe body is provided with an outer PVC pipe layer 1 and an inner PVC pipe layer 2 suspended inside, a plurality of springs 3 fixed on the inner wall are arranged between the outer PVC pipe layer 1 and the inner PVC pipe layer 2, a plurality of insulating pipes 4 for passing and releasing cables are arranged on the inner side of the inner PVC pipe layer 2, an inner soft rubber layer 5 is filled between the insulating pipes 4 and the inner PVC pipe layer 2, an outer soft rubber layer 6 is further coated on the surface of the outer PVC pipe layer 1, the outer PVC pipe layer 1 and the inner PVC pipe layer 2 can buffer the pressure of the inner layer to the inner layer by virtue of the elasticity of the springs 3, the structure of the inner layer can be protected from deformation, the springs 3 are suspended and fixed on the periphery, the pressure on the periphery and the protectiveness can be better, and the overall compressive resistance can be better improved.

The utility model discloses a communication pipe body, including PVC outer pipe layer 1 and PVC inner tube layer 2, the outer pipe layer 1 of PVC and PVC inner tube layer 2 inner wall all are connected with inserts the 3 inboard fixed spliced poles 7 of spring, outer pipe layer 1 of PVC and PVC inner tube layer 2 still are equipped with the recess 8 that the spring 3 was put to the card, and spliced pole 7 combines together fixed inboard spring 3 with recess 8, has improved the fixity of spring 3, has effectively prevented that the phenomenon that the spring 3 appears shifting or drops when the pressurized of communication pipe body.

The insulating tubes 4 are annularly distributed on the inner side of the PVC inner tube layer 2, the number of the insulating tubes 4 is at least 3, the number of the insulating tubes 4 needs to balance the internal structure and balance the stress conditions around, and therefore when the number of the insulating tubes 3 is at least 3, the balance force is better.

The 2 inboard fixed adhesive tape 9 of fixing at a plurality of insulating tube 4 centers that still are equipped with in the PVC interior pipe layer, fixed adhesive tape 9 is used for fixed a plurality of insulating tube 4 central points to put, prevents that a plurality of insulating tubes 4 from extruding toward the center and being in the same place.
