Description

Technical Field

[0001] The utility model relates to the technical field of CPVC cable protection tubes, in particular to a CPVC cable protection tube with a protective end cover. Background Art

[0002] CPVC cable protection tubes, also known as CPVC power tubes, are widely used in cable laying in urban power grid construction and renovation, urban municipal renovation projects, civil aviation airport engineering construction, transportation, road and bridge engineering construction, etc., playing a guiding and protective role. Since CPVC cable protection tubes are often buried underground, the wear resistance of CPVC cable protection tubes is particularly important.

[0003] The patent document with application number CN218300893U discloses a wear-resistant CPVC cable protection tube, which relates to the technical field of CPVC cable protection tubes, and includes an outer tube body and an inner tube body. The outer tube body is sleeved on the outside of the inner tube body, and the outer surface of the outer tube body is welded with spiral convex strips in a spiral manner. The outer surface of the inner tube body is sleeved with multiple rings, and the outer surface of the rings is uniformly welded with multiple rubber balls. The left and right ends of the outer tube body are connected with conical sleeves through threads, and the conical sleeves at the left and right ends are respectively inserted into the left and right ends of the inner tube body. By arranging spiral convex strips on the outer surface of the outer tube body, the wear resistance of the outer tube body can be improved. By dividing the tube body of the cable protection tube into an inner tube body and an outer tube body, when the outer tube body is severely worn and fails, only the outer tube body needs to be removed from the outside of the inner tube body, so that the outer tube body can be replaced without replacing the entire pipeline, which can reduce the maintenance cost of the cable protection tube.

[0004] In the above-mentioned related technologies, the outer tube body and the inner tube body are provided so that the outer tube body can be replaced after the outer tube body is severely worn. However, the connection between the above-mentioned tube body and the cable connection lacks an end cover to strengthen the sealing of the connection between the cable and the tube body. Moisture can easily enter the inside of the tube body and cause external damage to the cable. To address the above-mentioned problems, we have introduced a CPVC cable protection tube with a protective end cover. Utility Model Content
