Description

Technical Field

[0001] This utility model belongs to the field of conduit technology, and in particular relates to a cable conduit with a protective structure. Background Technology

[0002] Cable conduits, as crucial infrastructure in power and telecommunications sectors, primarily protect cables, differentiate circuit functions, and facilitate wiring and maintenance. In practical applications, depending on the specific needs of each scenario, corrosion-resistant and leakage-proof rigid PVC conduits, as well as iron, stainless steel, and carbon steel pipes, are commonly used. However, existing traditional cable conduits have significant drawbacks: First, when cables pass through the conduit, friction occurs between the cable and the conduit wall, causing wear on the cable's outer surface and increasing friction, requiring considerable pulling force to move the cable. Second, when multiple small-gauge cables are run through the conduit, the lack of internal insulation means that during unforeseen events such as earthquakes or construction vibrations, the cables rub against each other, leading to insulation damage and potential short circuits and leakage, severely impacting the lifespan of the circuit and system stability.

[0003] Therefore, it is essential to invent a cable conduit with a protective structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable conduit with a protective structure, including a conduit body, guide rails, cable seats and cables. The inner wall of the conduit body is provided with symmetrical guide rails, and several cable seats are rotatably mounted on the guide rails provided on the inner wall of the conduit body. Several cables pass through the cable seats in sequence and are fixed on the cable seats.

[0005] Preferably, the conduit body and the guide rail are integrally injection molded, the guide rail is a U-shaped protrusion, and several cable seats are equidistantly distributed along the axis of the conduit body and roll in cooperation with the guide rail.

[0006] Preferably, the cable holder includes a support partition, a notch, a roller, a wire hole, a fixing ring, and a limiting ring. The support partition has a plurality of notches on its outer ring, and a roller is rotatably installed in each notch. The support partition has wire holes evenly distributed throughout it. The fixing rings are fixedly provided on both sides of the support partition. The cable passes through the corresponding wire hole and is fixed and limited by the fixing rings and limiting rings.

[0007] Preferably, the outer diameter of the support partition is smaller than the inner diameter of the conduit body, and the roller rotatably installed at the notch of the support partition rolls together with the corresponding guide rail.

[0008] Preferably, the fixing rings fixedly installed on the support partition are corresponding to the wire holes, that is, the fixing rings are provided above the openings at both ends of each wire hole.

[0009] Preferably, the fixing ring and the limiting ring have the same structure, with corresponding through holes at both ends. The limiting ring is installed together with the fixing ring fixedly installed on the support partition seat by bolts, and restricts the corresponding cable on the inner side.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model provides a cable conduit with a protective structure, which effectively solves the shortcomings of traditional technologies through innovative design. The main body of the conduit and the U-shaped guide rail are integrally injection molded, forming a distributed support system in conjunction with the rolling cable seat. The cable seat is rolled along the guide rail, which not only enhances the overall compressive strength of the conduit, enabling it to maintain structural stability under external pressure, but also disperses pressure, avoiding damage to the cable caused by local stress concentration. At the same time, the support partition of the cable seat rolls with the guide rail through rollers at the notch, reducing friction during cable installation, facilitating construction, and reducing the burden and friction during cable installation.

[0012] Furthermore, the cable holder of this utility model combines wire holes with fixing rings and limiting rings to achieve independent fixing and separation of multiple cables, preventing them from contacting and rubbing against each other. When external vibrations or displacement occur, the separation structure can prevent wear between cables, effectively protecting the cable insulation layer and improving line safety and service life. In addition, the cable holders are evenly distributed inside the conduit, providing support for the conduit while optimizing the internal space layout, facilitating later cable inspection and replacement, and significantly improving engineering practicality and maintenance efficiency.

[0020] As attached Figure 1 To be continued Figure 3 As shown:

[0021] This utility model provides a cable conduit with a protective structure, including a conduit body 1, a guide rail 2, a cable seat 3, and a cable 4. The inner wall of the conduit body 1 is provided with symmetrical guide rails 2. Several cable seats 3 are rolled on the guide rails 2 provided on the inner wall of the conduit body 1. Several cables 4 pass through the cable seats 3 in sequence and are fixed on the cable seats 3.

[0022] Furthermore, the main body 1 of the conduit is made of high-strength flame-retardant PVC material and integrally molded through injection molding, possessing excellent insulation, corrosion resistance, and compressive strength. The guide rail 2 has a U-shaped protrusion structure and is injection molded simultaneously with the main body 1 of the conduit. Both have the same material and mechanical properties, ensuring structural stability. The groove width and depth of the U-shaped guide rail 2 are precisely designed to fit the size of the rollers 33 of the cable seats 3. Several cable seats 3 are equidistantly distributed along the axial direction of the main body 1 of the conduit. The grooves of the rollers 33 are embedded in the U-shaped guide rail 2, forming a rolling fit, which can effectively reduce the friction when the cable seats 3 move, while enhancing the overall compressive load-bearing capacity of the conduit.

[0023] Furthermore, the cable holder 3 consists of a support partition 31, notches 32, rollers 33, wire holes 34, fixing rings 35, and limiting rings 36. The support partition 31 is injection molded from engineering plastic, featuring lightweight and high toughness, with multiple notches 32 evenly distributed on its outer ring. Rollers 33 are mounted within each notch 32 via bearings. The rollers 33 are made of wear-resistant rubber, with a smooth surface and good rolling performance, reducing wear between them and the guide rail 2. Wire holes 34 are evenly distributed throughout the support partition 31 for threading cables 4; the diameter of the wire holes 34 is designed according to the specifications of the cables 4, ensuring smooth cable passage and maintaining appropriate clearance. Fixing rings 35 are integrally molded on both sides of the support partition 31 using an injection molding process. The fixing rings 35 correspond one-to-one with the wire holes 34, providing an installation base for fixing the cables 4.

[0024] Furthermore, the outer diameter of the support separator 31 is precisely designed to be smaller than the inner diameter of the conduit body 1, with a 3-5mm gap between them. This ensures that the cable holder 3 can move freely while preventing direct contact and friction with the inner wall of the conduit. The roller 33 installed at the notch 32 is tightly embedded in the U-shaped groove of the guide rail 2, with its outer surface fitting against the inner wall of the guide rail 2, forming a stable rolling connection. The cable holder 3 can slide smoothly along the guide rail 2, ensuring the cable's stable position within the conduit and dispersing the impact of external pressure on the cable.

[0025] Furthermore, the fixing rings 35 on the support separator 31 are precisely aligned with the wire holes 34, with a fixing ring 35 positioned directly above the openings at both ends of each wire hole 34. The fixing rings 35 have a semi-circular structure, and their inner diameter matches that of the wire holes 34. The design position of the fixing rings 35 facilitates their cooperation with the limiting rings 36, forming a double fixation for the cable 4, ensuring that the cable will not undergo axial or radial displacement within the conduit, and effectively preventing friction between multiple cables.

[0026] Furthermore, both the retaining ring 35 and the limiting ring 36 are made of high-strength nylon, possessing excellent weather resistance and anti-aging properties. They share the same structure, being semi-circular with through holes at both ends. During assembly, after the cable 4 is passed through the wire hole 34, the limiting ring 36 is placed over the cable 4, aligning its through hole with the through hole of the retaining ring 35. Stainless steel bolts are then used to secure the limiting ring 36 and the retaining ring 35 through the through holes. The bolt tightening force has been optimized to firmly secure the cable 4 while preventing damage to the cable insulation layer due to excessive pressure, thus achieving reliable cable fixation and protective separation.

[0027] The working principle is as follows: First, during construction, multiple cables 4 are passed through the wire holes 34 of multiple cable seats 3 in sequence. Using high-strength nylon fixing rings 35 and limiting rings 36, the cables 4 are fastened to the support partition seat 31 by stainless steel bolts, so as to achieve independent separation and fixation of multiple cables 4.

[0028] Next, the cable holder 3 with cable 4 is inserted along the U-shaped guide rail 2 on the inner wall of the conduit body 1, and the roller 33 is embedded in the groove of the guide rail to form a rolling fit. The cable holder 3 can slide freely along the guide rail 2. This design greatly reduces the friction during the cable 4 installation process, making the construction more convenient and efficient.

[0029] Then, when the main body 1 of the conduit is subjected to external pressure (such as the soil pressure when buried), the equidistantly distributed cable seats 3, through the contact between the rollers 33 and the guide rails 2 (and after a certain degree of deformation, they will contact the outer surface of the support partition seat 31), distribute the pressure to the entire inner wall of the conduit. The gap reserved between the support partition seat 31 and the main body 1 of the conduit avoids direct friction between the cable seats 3 and the conduit wall, and its lightweight and high toughness characteristics can buffer the pressure and prevent the conduit from deforming.

[0030] Finally, under the influence of uncontrollable factors such as external vibration or displacement, because cable 4 is independently fixed within cable seat 3, the separation structure prevents mutual contact and friction between cables 4. The dual fixing design of fixing ring 35 and limiting ring 36 ensures that cable 4 will not shift, effectively protecting the insulation layer of cable 4 and ensuring the safe and stable operation of the line.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
