Technical Field

[0001] The present application relates to the technical field of cable pipes, and in particular to an inner conduit for facilitating the installation of cables. Background Art

[0002] Cable conduits are usually made of materials such as metal, plastic or rubber. Their main function is to fix the cables in the conduit during the cable laying process to prevent the cables from mechanical damage, chemical corrosion or the influence of the external environment, thereby ensuring the normal operation and service life of the cables.

[0003] When used in an inner conduit, it protects the cable or optical cable, reduces the impact of external impact, corrosive environment, etc. on the cable or optical cable, reduces the impact on the service life of the cable or optical cable, and protects the normal use of the cable or optical cable.

[0004] When the inner conduit is used, it is mostly used to protect the cable or optical cable, reduce the impact of chemical corrosion and external impact on the cable, and ensure the service life of the cable. However, when the inner conduit of the cable is installed, two adjacent inner conduits are usually melted and connected by hot melting, which is inconvenient to install and easily affects the installation efficiency. After the installation is completed, the subsequent disassembly needs to be carried out by cutting off the conduit for maintenance and inspection, which is inconvenient and easily affects the installation and maintenance of the staff. Utility Model Content

[0008] By adopting the above technical solution, the pipe body is installed through the installation mechanism, which improves the installation efficiency, facilitates the maintenance and inspection of the cable by the staff, and facilitates the use of the cable. After the pipe body is fixed, the cable is inserted into the pipe body and fixed, which is convenient for the protection and use of the cable.

[0009] Furthermore, the installation mechanism includes a limiting frame fixed on sleeve one and distributed in an array, a fixing frame fixed on sleeve two and distributed in an array, the fixing frame corresponds to the limiting frame, the fixing frame and the limiting frame are both L-shaped, and a limiting component is arranged between the tube body and sleeve one.

[0010] By adopting the above technical solution, the limiting frame is moved to the fixing frame for clamping, so that the two limiting holes are aligned, thereby limiting the tube body.

[0012] By adopting the above technical solution, the fixing ring is moved into the fixing groove, which facilitates the connection and installation of the pipe body.

[0013] Furthermore, the limiting member includes a fixed column fixed on sleeve 2, a limiting column is slidably arranged inside the fixed column, a spring is fixed to the end of the limiting column, one end of the spring away from the limiting column is fixedly connected to the fixed column, and the limiting column extends out of the fixed column and into the limiting hole.

[0014] By adopting the above technical solution, the limiting column is moved to compress the spring, and the limiting column slides into the limiting hole in the fixed column, which facilitates the installation of the pipe body and improves the installation efficiency.

[0017] Furthermore, the wear-resistant layer is made of polyvinyl chloride, and the wear-resistant layer is fixedly connected to the supporting layer.

[0018] By adopting the above technical solution, the wear-resistant layer increases the wear resistance and service life of the pipe body.

[0019] Furthermore, the support layer is made of metal.

[0024] 1. When the inner conduit is in use, the staff moves the tube body to drive the fixing ring to move, so that the fixing ring moves into the fixing groove. At the same time, the tube body drives the sleeve 1 to contact the sleeve 2. When the fixing ring moves into the fixing groove, the limiting column is moved to compress the spring, and the limiting column slides in the fixing column. Then the tube body is rotated to move the sleeve 1. The movement of the sleeve 1 drives the limiting frame to move, so that the limiting frame moves to the fixed frame and engages, so that the two limiting holes are aligned. When the limiting column is released, the elastic force of the spring makes the limiting column enter the limiting hole to limit the sleeve 1, thereby improving the installation efficiency, facilitating the connection between the tube bodies, and facilitating the inspection and maintenance of the cable.

[0025] 2. When the inner conduit is in use, when the cable is inserted into the tube body, the cable contacts the rolling column, causing the rolling column to rotate on the support plate, which is convenient for the cable connection and reduces the friction between the cable and the inner wall of the tube body. When in use, the wear-resistant layer increases the wear resistance and service life of the tube body, the support layer increases the support of the tube body, which is convenient for protecting the cable, and the glass fiber cotton layer increases the fireproof effect of the tube body, which is convenient for protecting the cable.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] An embodiment of the present application discloses an inner conduit that is convenient for installing cables.

[0034] Reference Figure 1 and Figure 2An inner conduit for facilitating installation of cables comprises a tube body 1, a sleeve 2 is fixed on one end of the tube body 1, a sleeve 2 is fixed on the end of the tube body 1 away from the sleeve 2, a wear-resistant layer 13 is arranged on the surface of the tube body 1, a support layer 14 is arranged on the inner surface of the wear-resistant layer 13, a flame-retardant layer 15 is arranged on the inner surface of the support layer 14, and an installation mechanism is arranged between the sleeve 2 and the sleeve 3.

[0035] When the inner conduit is used, the tube body 1 is first fixed to the position where the cable needs to be installed, and then the tube body 1 is installed through the installation mechanism, which improves the installation efficiency, facilitates the staff to maintain and inspect the cable, and facilitates the use of the cable. After the tube body 1 is fixed, the cable is inserted into the tube body 1 and fixed, which is convenient for the protection and use of the cable.

[0036] Reference Figure 1-Figure 3 The installation mechanism includes a limiting frame 5 fixed on the sleeve 1 2 and distributed in an array, a fixing frame 4 is fixed on the sleeve 2 3 and distributed in an array, the fixing frame 4 corresponds to the limiting frame 5, and both the fixing frame 4 and the limiting frame 5 are L-shaped, and a limiting component is arranged between the tube body 1 and the sleeve 1 2. The limiting component includes a fixing ring 7 fixed on one end of the tube body 1, and a fixing groove 8 is provided at the end of the tube body 1 away from the fixing ring 7, and the fixing ring 7 corresponds to the fixing groove 8. The limiting frame 5 and the fixing frame 4 are both provided with limiting holes 6, and a limiting member is arranged between the sleeve 2 3 and the fixing frame 4. The limiting member includes a fixing column 9 fixed on the sleeve 2 3, and a limiting column 10 is slidably arranged in the fixing column 9, and a spring 11 is fixed at the end of the limiting column 10, and the end of the spring 11 away from the limiting column 10 is fixedly connected to the fixing column 9, and the limiting column 10 extends out of the fixing column 9 and extends into the limiting hole 6.

[0037] When the inner conduit is in use, the staff moves the tube body 1 to drive the fixing ring 7 to move, so that the fixing ring 7 moves into the fixing groove 8. At the same time, the tube body 1 drives the sleeve 1 2 to contact the sleeve 2 3. When the fixing ring 7 moves into the fixing groove 8, the limiting column 10 is moved again to compress the spring 11, and the limiting column 10 slides in the fixing column 9. Then the tube body 1 is rotated to move the sleeve 1 2. The movement of the sleeve 1 2 drives the limiting frame 5 to move, so that the limiting frame 5 moves to the fixing frame 4 and engages, so that the two limiting holes 6 are aligned. When the limiting column 10 is released, the elastic force of the spring 11 makes the limiting column 10 enter the limiting hole 6 to limit the sleeve 1 2, which is convenient for the installation of the tube body 1. When disassembly is required, the limiting column 10 is pulled to move to the limiting hole 6, the spring 11 is compressed, and the tube body 1 is rotated again to make the limiting frame 5 away from the fixing frame 4. The tube body 1 is pulled to make the fixing ring 7 disengage from the fixing groove 8, which is convenient for the staff to inspect and maintain the cable. Through the installation mechanism, the installation efficiency is improved, the connection between the tube bodies 1 is convenient, and the inspection and maintenance of the cable is convenient.

[0038] Reference Figure 2 and Figure 4Two symmetrical support plates 16 are fixed to the inner wall of the tube body 1, and a rolling column 17 is arranged between the two support plates 16, and the rolling column 17 is rotatably connected to the support plate 16, and the rolling column 17 is arranged in an array. The wear-resistant layer 13 is made of polyvinyl chloride, and the wear-resistant layer 13 is fixedly connected to the support layer 14. The support layer 14 is made of metal. The flame retardant layer 15 is made of glass fiber cotton layer, and the flame retardant layer 15 is fixedly connected to the support layer 14.

[0039] When the inner conduit is in use, when the cable is inserted into the tube body 1, the cable contacts the rolling column 17, so that the rolling column 17 rotates on the support plate 16, which is convenient for the insertion of the cable and reduces the friction between the cable and the inner wall of the tube body 1. When in use, the wear-resistant layer 13 increases the wear resistance and service life of the tube body 1, the support layer 14 increases the support of the tube body 1, which is convenient for protecting the cable, and the glass fiber cotton layer increases the fireproof effect of the tube body 1, which is convenient for protecting the cable.

[0040] The implementation principle of the inner conduit for facilitating the installation of cables in the present embodiment is as follows: when the conduit is used, the tube body 1 is first fixed to the position where the cable needs to be installed, and the staff moves the tube body 1 to drive the fixing ring 7 to move, so that the fixing ring 7 moves into the fixing groove 8. At the same time, the tube body 1 drives the sleeve 1 2 to contact the sleeve 2 3. When the fixing ring 7 moves into the fixing groove 8, the limiting column 10 is moved again to compress the spring 11, and the limiting column 10 slides in the fixing column 9. Then, the tube body 1 is rotated to move the sleeve 1 2. The movement of the sleeve 1 2 drives the limiting frame 5 to move, so that the limiting frame 5 moves to the fixing frame 4 and engages, so that the two limiting holes 6 are aligned. When the limiting column 10 is released, the elastic force of the spring 11 causes the limiting column 10 to enter the limiting hole 6, and the installation of the tube body 1 is completed.

[0041] Then plug the cable into the tube body 1. When the cable is inserted into the tube body 1, the cable contacts the rolling column 17, so that the rolling column 17 rotates on the support plate 16, which is convenient for the insertion of the cable and reduces the friction between the cable and the inner wall of the tube body 1. The cable is fixed after insertion. When in use, the wear-resistant layer 13 increases the wear resistance and service life of the tube body 1, the support layer 14 increases the support of the tube body 1, which is convenient for protecting the cable, and the glass fiber cotton layer increases the fireproof effect of the tube body 1, which is convenient for protecting the cable.
