Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a PVC cable protection pipe. Background Technology

[0002] Cable protection pipes are protective tubes laid on the outer layer of cables to prevent damage. They possess a certain mechanical strength and can extend the service life of cables. However, existing cable protection pipes are cumbersome to connect and install, time-consuming and labor-intensive, resulting in low installation efficiency. In addition, the sealing between the protective pipes is not good enough, allowing rainwater to easily enter the interior, causing the cable to be submerged in water for a long time, which can easily lead to cable creep.

[0003] To solve the above problems, a new type of cable protection pipe is needed that combines the advantages of easy installation and good sealing performance. Summary of the Invention

[0004] The purpose of this utility model is to provide a PVC cable protection pipe that solves the problems of low installation efficiency and poor sealing performance of existing cable protection pipes.

[0005] To achieve the above objectives, this utility model provides a PVC cable protection pipe, including a pipe body. Two protruding rings are fixedly connected to the outer wall of the pipe body, and the two protruding rings are respectively arranged adjacent to two ends of the pipe body. A connector is provided at one of the ends. The connector includes a shell and a sealing cylinder arranged coaxially. The shell is provided with at least one through groove arranged along its length direction. The through groove includes a middle section and guide sections located at both ends of the middle section. A spring is provided in the middle section. The natural length of the spring is less than the length of the middle section. The diameter of the guide section is less than the diameter of the spring. A hook is provided in the guide section. One end of the hook is fixedly connected to the spring. The other end of the hook is arranged opposite to the side of the adjacent protruding ring near the middle section of the pipe body. The sealing cylinder is fixedly connected to the middle part of the inner wall of the shell. The end face of the sealing cylinder is arranged opposite to the end face of the end.

[0006] Preferably, both ends of the sealing cylinder are provided with slots that are adapted to the end structure.

[0007] Preferably, the outer casing is provided with a fixing bolt whose bottom end extends into the guide section, and the hook is provided with a threaded hole that is compatible with the structure of the fixing bolt.

[0008] Preferably, the sealing cylinder is made of rubber.

[0009] Preferably, the sealing cylinder is bonded to the outer shell.

[0010] Preferably, there are two through slots.

[0011] Therefore, the PVC cable protection pipe of this utility model with the above-described structure has the following beneficial effects:

[0012] 1. The elasticity of the spring can be used to make two hooks pull on a convex ring on two pipes respectively, thereby realizing the connection between the two pipes and improving the installation efficiency between the pipes.

[0013] 2. After the two hooks pull on a convex ring on each of the two pipes, the ends of the two pipes are tightly attached to the sealing cylinder, thereby achieving a sealed connection between the two pipes and improving the sealing performance between the pipes.

[0014] 3. Fixing bolts can be used to increase the stability of the hook position, thereby improving the connection strength and sealing reliability between pipes.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example

[0022] like Figure 1-2As shown, a PVC cable protection pipe includes a pipe body 1. Two protruding rings 2 are fixedly connected to the outer wall of the pipe body 1, and the two protruding rings 2 are respectively arranged adjacent to two ends of the pipe body 1, with a connector provided at one end. The connector includes a housing 3 and a sealing cylinder 4 arranged coaxially. The housing 3 is provided with at least one through groove 5 arranged along its length direction. The through groove 5 includes a middle section and guide sections located at both ends of the middle section. In this embodiment, there are two through grooves 5. A spring 6 is provided in the middle section. The natural length of the spring 6 is less than the length of the middle section, and the spring 6 can be stretched within the middle section. The diameter of the guide section is less than the diameter of the spring 6, and a hook 7 is provided in the guide section. The guide section can prevent the spring 6 from coming out of the middle section and can guide the movement direction of the hook 7. One end of the hook 7 is fixedly connected to the spring 6, and the other end of the hook 7 is arranged opposite to the side of the adjacent protruding ring 2 near the middle section of the pipe body 1. The sealing cylinder 4 is made of rubber and is fixedly connected to the middle part of the inner wall of the housing 3. The fixed connection method can be adhesive bonding. The end face of the sealing cylinder 4 is positioned opposite to the end face of the end head. After the hook 7 hooks the convex ring 2, the end head can be pressed tightly against the sealing cylinder 4. Both ends of the sealing cylinder 4 are provided with slots 8 that are adapted to the end head structure. The slots 8 can increase the sealing performance and connection stability between the pipe body 1 and the sealing cylinder 4.

[0023] The outer casing 3 is provided with a fixing bolt 9 whose bottom end extends into the guide section, and the hook 7 is provided with a threaded hole that matches the structure of the fixing bolt 9. The cooperation between the fixing bolt 9 and the threaded hole can ensure the stability of the position of the hook 7, thereby increasing the stability of the connection between the two tubes 1 and the sealing performance of the connection between the two tubes 1.

[0024] In use, the tube body 1 and the connector can be transported in batches separately. During installation, pull the hooks 7 at both ends of the connector in a direction away from each other, and then insert one end of each of the two tube bodies 1 into the two grooves of the connector. After releasing the hooks 7, the hooks 7 retract under the action of the spring 6 and hook a protrusion 2 on each of the two tube bodies 1. At this time, the two tube bodies 1 are connected under the action of the spring 6 and the hooks 7. The grooves can ensure the sealing of the connection. Finally, tighten the fixing bolts 9 to increase the stability of the connection between the two tube bodies 1.

[0025] Therefore, this utility model adopts the above-mentioned structure of a PVC cable protection pipe, which combines the advantages of easy installation and good sealing performance.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
