Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically a pressure-resistant cable protection pipe. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at intersections where communication cables and power lines cross. They prevent short circuits caused by power line breaks, which could energize communication cables and steel wire ropes, thus protecting cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines. With the development of technology, cement or other non-metallic composite materials are gradually being replaced by fiberglass. Most cable protection pipes made of fiberglass offer improved corrosion resistance and lifespan underground, a smooth surface, and resistance to high temperatures and pressure.

[0003] Currently, conventional pressure-resistant cable protection pipes have a rigid structure, resulting in poor buffering performance during use and hindering cable bending. During use, the inner tube adheres closely to the cable, causing poor heat dissipation. They also lack insulation, heat insulation, and electromagnetic interference resistance, and their outer surface is easily dragged and worn, making them unsuitable for use. Therefore, we propose a pressure-resistant cable protection pipe to solve the above problems. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a pressure-resistant cable protection pipe, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A pressure-resistant cable protection pipe includes an inner tube, on the inner wall of which rubber protrusions are uniformly fixedly installed circumferentially, and buffer mechanisms are uniformly arranged on the left and right sides of the outer surface of the inner tube. A protective mechanism is sleeved between the outer surfaces of the buffer mechanisms, and an outer tube is fixedly sleeved on the outer surface of the protective mechanism. Anti-wear protrusions are uniformly fixedly installed circumferentially on the outer surface of the outer tube.

[0006] Furthermore, the inner tube and the rubber protrusion are integrally formed.

[0007] Furthermore, the buffer mechanism includes a metal sleeve, an annular silicone airbag, and a one-way air intake valve. The metal sleeve is fixedly installed on the outer surface of the inner tube, and an annular silicone airbag is fixedly sleeved on the outer surface of the metal sleeve. A one-way air intake valve is provided on the left side wall of the annular silicone airbag.

[0008] Furthermore, the protective mechanism includes an insulating rubber sleeve, a heat insulation film, and a metal shielding mesh sleeve. The insulating rubber sleeve is fitted onto the outer surface of the annular silicone airbag, the heat insulation film is wrapped around the outer surface of the insulating rubber sleeve, and the metal shielding mesh sleeve is wrapped around the outer mold of the heat insulation film.

[0009] Furthermore, the metal shielding mesh is embedded in the inner wall of the outer tube.

[0010] Furthermore, the anti-wear protrusions and the outer tube are integrally formed.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a pressure-resistant cable protection pipe, which has the following beneficial effects: This invention significantly improves the compressive strength of the protective tube through a buffer mechanism, and can meet the bending requirements of the cable. The gap between adjacent rubber protrusions increases the heat dissipation space of the cable. Furthermore, the protective mechanism enhances the insulation, heat insulation, and electromagnetic interference resistance of the protective tube, enabling it to be used in various environments. In addition, the anti-wear protrusions improve the wear resistance of the outer surface of the tube, making it less prone to friction damage and facilitating its use. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example like Figures 1-3As shown, an embodiment of the present invention provides a pressure-resistant cable protection pipe, including an inner tube 1. Rubber protrusions 2 are uniformly fixedly installed on the inner wall of the inner tube 1 along the circumference. Buffer mechanisms 3 are uniformly arranged on the left and right sides of the outer surface of the inner tube 1. A protective mechanism 4 is sleeved between the outer surfaces of the buffer mechanisms 3. An outer tube 5 is fixedly sleeved on the outer surface of the protective mechanism 4. Anti-wear protrusions 6 are uniformly fixedly installed on the outer surface of the outer tube 5 along the circumference.

[0016] like Figure 3 As shown, in some embodiments, the inner tube 1 and the rubber protrusion 2 are integrally formed.

[0017] In this embodiment, the structure between the inner tube 1 and the rubber protrusion 2 is strong, and neither the inner tube 1 nor the rubber protrusion 2 is easily damaged.

[0018] like Figure 2 and Figure 3 As shown, in some embodiments, the buffer mechanism 3 includes a metal sleeve 301, an annular silicone airbag 302, and a one-way air intake valve 303. The metal sleeve 301 is fixedly installed on the outer surface of the inner tube 1. The annular silicone airbag 302 is fixedly sleeved on the outer surface of the metal sleeve 301. The one-way air intake valve 303 is provided on the left side wall of the annular silicone airbag 302.

[0019] In this embodiment, the metal sleeve 301 enhances the strength of the inner tube 1 and provides better support for the annular silicone airbag 302. The annular silicone airbag 302 increases the pressure-resistant buffer function of the outer tube 5 on the outer surface of the protective mechanism 4. The one-way air inlet valve 303 is used to inflate the annular silicone airbag 302 in one direction. The metal sleeve 301 and the annular silicone airbag 302, which are spaced apart on the left and right, can accommodate the bending of the cable at a certain angle.

[0020] like Figure 2 and Figure 3 As shown, in some embodiments, the protective mechanism 4 includes an insulating rubber sleeve 401, a heat insulation film 402, and a metal shielding mesh sleeve 403. The insulating rubber sleeve 401 is sleeved on the outer surface of the annular silicone airbag 302. The heat insulation film 402 is wrapped around the outer surface of the insulating rubber sleeve 401. The metal shielding mesh sleeve 403 is wrapped around the outer mold of the heat insulation film 402.

[0021] In this embodiment, the insulating rubber sleeve 401, the heat insulation film 402, and the metal shielding mesh sleeve 403 enhance the insulation, heat insulation, and electromagnetic interference resistance of the outer tube 5, thereby enabling it to meet the installation and use requirements of various environments.

[0022] like Figure 2 and Figure 3 As shown, in some embodiments, the metal shielding mesh 403 is embedded in the inner wall of the outer tube 5.

[0023] In this embodiment, the connection between the metal shielding mesh sleeve 403 and the outer tube 5 is strong and not easily detached or damaged.

[0024] like Figures 1-3 As shown, in some embodiments, the anti-wear protrusion 6 and the outer tube 5 are integrally formed.

[0025] In this embodiment, the anti-wear protrusion 6 and the outer tube 5 have high structural strength, making the anti-wear protrusion 6 less likely to fall off or be damaged, thus extending its service life.

[0026] In use, the cable is inserted into the inner tube 1. The gap between the inner wall of the inner tube 1 and the cable is increased by the rubber protrusion 2 to meet the heat dissipation requirements of the cable. The metal sleeve 301 in the buffer mechanism 3 enhances the strength of the inner tube 1 and provides good support for the annular silicone airbag 302. The annular silicone airbag 302 increases the pressure-resistant buffer function of the outer tube 5 on the outer surface of the protective mechanism 4. The one-way air inlet valve 303 is used to inflate the annular silicone airbag 302 in one direction. The metal sleeve 301 and the annular silicone airbag 302, which are spaced apart on the left and right, can accommodate the bending of the cable at a certain angle, greatly improving the pressure resistance of the protective tube. The insulating rubber sleeve 401, the heat insulation film 402 and the metal shielding mesh sleeve 403 in the protective mechanism 4 increase the insulation, heat insulation and anti-electromagnetic interference functions of the outer tube 5, so as to meet the installation and use in various environments. The anti-wear protrusion 6 improves the wear resistance of the outer surface of the outer tube 5, making it less prone to friction damage and facilitating use.

[0027] In summary, this pressure-resistant cable protection pipe, through the buffer mechanism 3, greatly improves the pressure resistance of the pipe, meets the bending requirements of the cable, increases the heat dissipation space of the cable, enhances the insulation, heat insulation and anti-electromagnetic interference functions, can meet the needs of use in various environments, and improves the wear resistance of the outer surface, which is beneficial to use.
