Abstract
Description
Technical Field
[0001] This utility model relates to the field of weather resistance technology for cable protection pipes, specifically a cable protection pipe with excellent weather resistance. Background Technology
[0002] Cable protection pipes are critical components used in power and telecommunications industries to protect cables from mechanical damage and environmental corrosion. Most existing cable protection pipes are made of PVC, PE, or metal, providing basic waterproofing and corrosion resistance. Some products enhance their UV resistance and resistance to high and low temperatures by adding fillers or modifiers. However, conventional protection pipes are prone to aging, embrittlement, or performance degradation when exposed to extreme climates (such as strong sunlight, rain, snow, and salt spray) for extended periods. Products optimized for weather resistance are often more expensive or have more complex manufacturing processes, making it difficult to balance economy and reliability.
[0003] Currently, weather-resistant cable protection pipes mostly rely on single-material modification (such as adding ultraviolet absorbers), which has limited improvement in weather resistance and may sacrifice other mechanical properties (such as impact resistance). In addition, existing technologies have insufficient research on the adaptability to complex environments (such as the synergistic effect of damp heat and ultraviolet radiation), resulting in products that are still prone to cracking, fading, or sealing failure in practical applications, leaving room for improvement. Utility Model Content
[0004] The purpose of this utility model is to provide a cable protection pipe with excellent weather resistance, so as to solve the problems mentioned in the background art and overcome its technical defects.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cable protection pipe with excellent weather resistance, comprising a corrugated pipe body and a protective pipe body, wherein the corrugated pipe body is telescopically oriented, the corrugated pipe body and the protective pipe body are arranged alternately, a matching pipe is fixedly connected to one side of the protective pipe body, the matching pipe is rotatably connected to the corrugated pipe body, and a stabilizing head is fixedly connected inside the protective pipe body, the stabilizing head being adapted to the cable.
[0006] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein the protection pipe body includes an outer layer, a sandwich layer and an inner layer, wherein the outer layer, the sandwich layer and the inner layer are arranged sequentially from the outside to the inside.
[0007] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein the corrugated pipe body includes a central corrugated pipe and an outer corrugated pipe, two sets of the outer corrugated pipes are respectively disposed at one end of the central corrugated pipe, and the outer corrugated pipes are fixedly connected to the central corrugated pipe.
[0008] As a further improvement of this utility model: a cable protection pipe with excellent weather resistance, wherein a protruding ball head is fixedly connected to one side of the stabilizing head, and the protruding ball head is in movable contact with the cable.
[0009] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein the outer end corrugated pipe has a sliding cavity inside, and the matching pipe includes a sliding tube and a limiting tube, wherein the sliding tube is adapted to the sliding cavity.
[0010] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein a limiting cavity is formed on one side of the sliding cavity, and the limiting tube is adapted to the limiting cavity.
[0011] As a further improvement of this utility model: a cable protection pipe with excellent weather resistance, wherein the outer surface of the convex ball head is polished.
[0012] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, further comprising a base, wherein the base is fixedly installed on one side of the protection pipe body and the base is in contact with the external environment.
[0013] Compared with the prior art, the beneficial effects of this utility model include:
[0014] Because the corrugated pipe body is telescopic, and the corrugated pipe body and the protective pipe body are arranged alternately, a matching pipe is fixedly connected to one side of the protective pipe body, and the matching pipe is rotatably connected to the corrugated pipe body. A stabilizing head is fixedly connected inside the protective pipe body, and the stabilizing head is adapted to the cable. Specifically, a sliding cavity is opened inside the outer end of the corrugated pipe, and the sliding pipe is adapted to the sliding cavity. A limiting cavity is opened on one side of the sliding cavity, and the limiting pipe is adapted to the limiting cavity. Therefore, when the cable inside the corrugated pipe body is slightly rotated due to assembly obstruction, the cable rotation problem can be corrected by rotating the protective pipe body at a small angle. This avoids the problem of incorrect positioning of the cable due to rotation during cable protection, and the problem of easy damage due to long-term compression with the protective pipe body.
[0015] Because the outer layer is made of high-density polyethylene (HDPE) with good wear resistance, cold brittleness resistance, and heat melt resistance, the interlayer is made of flame-retardant modified polyethylene (FR-PP) with fire resistance and heat insulation, and the inner layer is made of ultra-high molecular weight polyethylene (UHMWPE) with excellent insulation and wear resistance, the protective pipe body has good weather resistance and its service life is effectively extended.

A limiting cavity 14 is opened on one side of the sliding cavity 13, and the limiting tube 32 is adapted to the limiting cavity 14. Therefore, when the cable inside the corrugated tube body 1 is slightly rotated due to assembly obstruction, the cable rotation problem can be corrected by rotating the protective tube body 2 at a small angle, avoiding the problem of incorrect position caused by cable rotation during cable protection and easy damage due to long-term squeezing with the protective tube body 2.
[0027] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein the protection pipe body 2 includes an outer layer 6, a sandwich layer 7 and an inner layer 8, wherein the outer layer 6, the sandwich layer 7 and the inner layer 8 are arranged sequentially from the outside to the inside, the outer layer 6 is made of high-density polyethylene (HDPE) with good wear resistance, cold brittleness resistance and heat melt resistance, the sandwich layer 7 is made of flame-retardant modified polyethylene (FR-PP) with flame resistance and heat insulation, and the inner layer 8 is made of ultra-high molecular weight polyethylene (UHMWPE) with excellent insulation and wear resistance.
[0028] Because the outer layer 6 is made of high-density polyethylene (HDPE) with good wear resistance, cold brittleness resistance, and heat melt resistance, the interlayer 7 is made of flame-retardant modified polyethylene (FR-PP) with fire resistance and heat insulation, and the inner layer 8 is made of ultra-high molecular weight polyethylene (UHMWPE) with excellent insulation and wear resistance, the protective tube body 2 has good weather resistance and its service life is effectively extended.
[0029] As a further embodiment of this utility model: a cable protection pipe with excellent weather resistance, wherein the corrugated pipe body 1 includes a central corrugated pipe 11 and an outer corrugated pipe 12, the two sets of outer corrugated pipes 12 are respectively disposed at one end of the central corrugated pipe 11, and the outer corrugated pipes 12 are fixedly connected to the central corrugated pipe 11.

A limiting cavity 14 is opened on one side of the sliding cavity 13. The limiting tube 32 is adapted to the limiting cavity 14. Therefore, when the cable inside the corrugated tube body 1 is slightly rotated due to assembly obstruction, the cable rotation problem can be corrected by rotating the protective tube body 2 at a small angle. This avoids the problem of incorrect position caused by cable rotation during protection and easy damage due to long-term compression with the protective tube body 2.
