Description

Technical Field

[0001] The utility model relates to the field of PVC wire pipes, in particular to a high-strength PVC wire pipe. Background Art

[0002] PVC wire tube, also known as wire tube or electrical conduit, is a straight conduit used to protect wires and cables. It is mainly used in industrial and construction projects below 2000V. Its main raw material is polyvinyl chloride resin, and other additives are added to make it through extrusion molding. PVC wire tube has many advantages, such as flame retardancy, insulation, easy installation, long service life, etc., so it has been widely used in home interior decoration and construction engineering water and electricity installation and other fields.

[0003] Publication (Announcement) No.: CN217607380U, a self-lubricating PVC wire pipe, the pipe adopts a double-layer structure, from inside to outside: the inner layer is a modified PVC silicone core lubricating layer, and the outer layer is a PVC layer. The pipe can improve the threading effect and prevent cable damage.

[0004] The applicant believes that the self-lubricating PVC wire pipe of the above-mentioned structure is only composed of a double-layer structure. The pipe is thin, low in strength, and has weak tensile and compressive resistance. Due to the large number of staff coming and going, the wire pipe is prone to being kicked and stepped on. In the long run, it will cause long-term pressure on the wire pipe and cannot withstand strong external pressure. Moreover, when the wires and cables are moved, the staff drags the wires and cables, causing the wire pipe to rub back and forth on the ground. After repeated movement or friction, the tensile resistance is poor, the wire pipe will fatigue and break, and the wires and cables inside will lose the function of power transmission and confidence transmission. Therefore, the above-mentioned double-layer structure pipe has low strength, poor tensile resistance, and poor compressive resistance. Long-term stepping and pulling by the staff will damage the wire pipe and affect the use of the internal wires and cables. Utility Model Content

[0005] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a high-strength PVC wire pipe, which can effectively solve the technical problems of low strength, poor tensile strength and poor compressive strength of the existing wire pipe.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a high-strength PVC wire pipe, comprising a pipe body and an outer sheath, the outer sheath is arranged on the outer surface of the pipe body, the outer sheath comprises a skeleton layer and an anti-stretching layer, the anti-stretching layer is arranged on the outer surface of the skeleton layer, a metal mesh layer is arranged inside the skeleton layer, the metal mesh layer is fixedly connected to the outer surface of the pipe body, a rubber coating layer is arranged outside the skeleton layer, the anti-stretching layer comprises a titanium steel layer and a PVC layer, the PVC layer is arranged on the outer surface of the titanium steel layer, and the titanium steel layer is fixedly connected to the inner surface of the rubber coating layer.

[0007] Furthermore, the tube body and the outer sheath are both hollow structures.

[0008] Furthermore, the thickness of the skeleton layer is greater than the thickness of the anti-stretching layer.

[0009] Furthermore, the thickness of the PVC layer is greater than the thickness of the titanium steel layer.
