Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically an assembled cable protection pipe. Background Technology

[0002] Cable protection conduits are tubular materials used to wrap and protect cables. Their primary function is to provide physical protection for power and communication cables, preventing damage during construction and operation from mechanical damage, chemical corrosion, moisture seepage, or extreme temperatures. They are typically made of durable materials such as PVC plastic, polyethylene (PE), galvanized steel pipe, or fiber-reinforced composite materials, possessing properties such as pressure resistance, corrosion resistance, insulation, and flame retardancy. Their design can adapt to various environmental requirements, such as direct underground burial, road crossings, or outdoor exposure. Cable protection conduits not only extend the service life of cables but also reduce the risk of power outages or signal interruptions caused by external damage. They are a key component in power systems, communication networks, and rail transit infrastructure, ensuring the safe and stable operation of lines.

[0003] Because existing cable protection pipes are designed as complete tubular tubes, when replacing them, the old cable protection pipe must be removed from the end of the cable before the new one can be installed. This is inconvenient for long cables or in confined spaces where replacement is not feasible, resulting in limited applicability and room for improvement. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an assembled cable protection pipe, including a protective inner pipe and a closed rail. The protective inner pipe is an open structure occupying three-quarters of the pipe's circumference, and the closed rail is an arc structure occupying one-quarter of the pipe's circumference. The closed rail is movably connected to the protective inner pipe. The protective inner pipe is used to accommodate the cable, and the closed rail is used to close or open the pipe.

[0006] As a further embodiment of this utility model: a prefabricated cable protection pipe, wherein a protective outer pipe is fixedly installed on the outer periphery of the inner protective pipe, and an anti-wear layer is fixedly installed on the outer periphery of the outer protective pipe.

[0007] As a further embodiment of this utility model: an assembled cable protection pipe, wherein a plug is fixedly installed inside the inner tube of the protection pipe, a second slot is opened inside the inner tube of the protection pipe, a first slot is opened on one side of the closed rail, one side of the first slot is adapted to the plug, and the other side of the first slot is adapted to the second slot.

[0008] As a further embodiment of this utility model: an assembled cable protection pipe, which further includes a first extrusion column and a second extrusion column, the first extrusion column and the second extrusion column are respectively fixedly connected to one side of the opening of the inner tube of the protection pipe, and both the first extrusion column and the second extrusion column are used for cable limiting.

[0009] As a further embodiment of this utility model: a prefabricated cable protection pipe, wherein a sliding cavity is provided inside the inner tube of the protection pipe, and the closed rail is movably connected to the sliding cavity.

[0010] As a further embodiment of this utility model: an assembled cable protection pipe, wherein a slide channel is provided inside the slide cavity, and a slider is fixedly connected to one side of the closed rail, the slider being adapted to the slide channel.

[0011] As a further embodiment of this utility model: an assembled cable protection pipe, which also includes a seal, the seal being connected to the beginning and end of the slide rail and providing anti-detachment protection for the slider inside the slide rail.

[0012] As a further embodiment of this utility model: an assembled cable protection pipe, wherein the first extrusion column and the second extrusion column are made of soft wear-resistant PU, and the wear-resistant layer is made of hard wear-resistant PU.

[0013] Compared with the prior art, the beneficial effects of this utility model include:

[0014] Because the inner protective tube is an open structure occupying three-quarters of the pipe's circumference, and the closed rail is an arc structure occupying one-quarter of the pipe's circumference, and the closed rail is movably connected to the inner protective tube, the inner protective tube is used to house the cable, and the closed rail is used to close or open the pipe, the protective sleeve can be assembled and used with the cable at a certain section of the cable as needed during cable protection, without having to send the old cable protective sleeve out from the end of the cable and then send the new cable protective sleeve in from the end of the cable, thus avoiding inefficient workflows and improving the assembly efficiency of the cable and cable protective sleeve.

Therefore, after the inner protective tube and the closed rail are closed, they can be stably clamped and fixed, avoiding the problem of loosening, and effectively realizing the protection of the cable.

Therefore, during cable protection, the protective sleeve can be assembled and used on a certain section of the cable as needed, without having to send the old cable protective sleeve out from the end of the cable and then send the new cable protective sleeve in from the end of the cable. This avoids ineffective workflows and improves the assembly efficiency of the cable and cable protective sleeve.

[0034] Working principle: Since the inner protective tube 1 is an open structure occupying three-quarters of the circumference of the pipe, and the closed rail 4 is an arc structure occupying one-quarter of the circumference of the pipe, the closed rail 4 is movably connected to the inner protective tube 1. The inner protective tube 1 is used to accommodate the cable, and the closed rail 4 is used to close or open the pipe. Therefore, when protecting the cable, the protective sleeve can be assembled and used on a certain section of the cable as needed, without having to send the old cable protective sleeve out from the end of the cable and then send the new cable protective sleeve in from the end of the cable. This avoids ineffective work processes and improves the assembly efficiency of the cable and the cable protective sleeve.

[0035] Because the inner protective tube 1 is fixedly installed with a plug 5, and the inner protective tube 1 has a second slot 12, and the closed rail 4 has a first slot 8 on one side, one side of the first slot 8 is adapted to the plug 5, and the other side of the first slot 8 is adapted to the second slot 12, the inner protective tube 1 and the closed rail 4 can be stably clamped and fixed after closing, avoiding the problem of loosening, and effectively realizing the protection of the cable.
