Description

Technical Field

[0001] This utility model relates to the field of power protection pipe technology, and in particular to a power protection pipe with a protective structure. Background Technology

[0002] In the construction industry, electrical protection pipes are installed inside walls to guide and protect cable wiring, protecting cables and wires from the effects of external environment and physical factors, and ensuring the safe, stable and efficient operation of the power system.

[0003] Existing power protection pipes have a relatively simple function, only providing pressure resistance to cables and lacking tensile protection. After cables are laid inside power protection pipes, they are prone to breakage when subjected to large external tensile forces. When the breakage is deep inside the pipe, reconnection requires pulling the cable out of the power protection pipe, reconnecting it, and then re-laying it back into the power protection pipe, which is inconvenient for maintenance work. Therefore, a power protection pipe with a protective structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a power protection tube with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power protection tube with a protective structure, comprising:

[0006] Power protection pipe;

[0007] A clamping mechanism is provided at the port of the power protection pipe, and the clamping mechanism is used to clamp the cable at the port of the power protection pipe.

[0008] Preferably, the clamping mechanism includes:

[0009] A guide ring is fixedly connected to the end of the inner wall of the power protection pipe. A frustum-shaped through hole is opened in the middle of the guide ring, and the diameter of the frustum-shaped through hole gradually increases along the direction close to the port of the power protection pipe.

[0010] The connecting ring has multiple elastic clips arranged in a ring array on the side facing the power protection pipe port. The elastic clips are sheet-shaped elastic metal.

[0011] Preferably, the outer diameter of the connecting ring is adapted to the diameter of the frustum through hole, and the elastic clip has a first conical surface on the side facing the guide ring.

[0012] Preferably, each of the multiple elastic clips has a positioning clip fixedly connected to the inner wall of its end near the guide ring, and the positioning clip has a second conical surface on the side facing the connecting ring.

[0013] Preferably, the port of the power protection tube is movably provided with a moving component, which is used to drive the connecting ring to move axially along the power protection tube.

[0014] Preferably, the moving component includes:

[0015] External thread groove, wherein the external thread groove is formed at the end of the outer wall of the power protection pipe;

[0016] The end cap has a threaded groove on its inner wall that matches the external threaded groove, and the end cap is fixedly connected to the connecting ring on the side facing the power protection pipe.

[0017] Compared with the prior art, the technical effects of this utility model are as follows:

[0018] This utility model, by setting a clamping mechanism at the opening of the power protection pipe, can prevent the cable inside the power protection pipe from being subjected to tensile force after the cable has passed through the power protection pipe and been wired. This ensures that the cable will only break at the clamping position when subjected to external tensile force, thus facilitating subsequent wiring and maintenance work. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] This utility model provides, for example Figures 1-3The illustrated power protection conduit with a protective structure includes a power protection conduit 100 and a clamping mechanism. The clamping mechanism is located at the port of the power protection conduit 100 and is used to clamp the cable at the port of the power protection conduit 100. By providing the clamping mechanism at the port of the power protection conduit 100, after the cable has been threaded through the power protection conduit 100 to complete the wiring work, the clamping mechanism can hold the cable at the port of the power protection conduit 100, thus preventing the cable inside the power protection conduit 100 from being subjected to tensile forces. Therefore, when external tensile forces act on... When the cable breaks, the breakage will only occur at the location where it is clamped by the clamping mechanism, without damaging the cable inside the power protection tube 100. Therefore, during subsequent maintenance and wiring, the user only needs to connect the external power supply to the cable end at the port of the power protection tube 100, without having to pull the entire cable out of the power protection tube 100 for wiring and then re-threading. This simplifies subsequent cable maintenance, improves efficiency, and ensures that the power protection tube 100 provides cable protection.

[0025] It should be noted that the clamping mechanism includes a guide ring 103 and a connecting ring 109. The guide ring 103 is fixedly connected to the inner wall end of the power protection pipe 100. A frustum-shaped through hole 104 is opened in the middle of the guide ring 103. The diameter of the frustum-shaped through hole 104 gradually increases along the direction close to the port of the power protection pipe 100. On the side of the connecting ring 109 facing the port of the power protection pipe 100, multiple elastic clips 105 are arranged in a ring array at intervals. The elastic clips 105 are sheet-shaped elastic metal. The outer diameter of the connecting ring 109 is adapted to the diameter of the port of the frustum-shaped through hole 104. The connecting ring 109 moves into the power protection pipe 100. The multiple elastic clips 105 are inserted through the frustum-shaped through-hole 104 on the guide ring 103. As the inner diameter of the frustum-shaped through-hole 104 gradually decreases, the inner wall of the frustum-shaped through-hole 104 exerts an inward squeezing force on the elastic clips 105 as they are continuously inserted. This causes the ends of the multiple elastic clips 105 to move closer to the center, thus reducing the distance between them and achieving a clamping effect on the outer wall of the cable. This allows the cable located at the port of the power protection pipe 100 to be clamped and fixed, thereby achieving the desired clamping effect on the cable located inside the power protection pipe 100. The cable is protected; the elastic clip 105 has a first conical surface 106 on the side facing the guide ring 103, and each of the multiple elastic clips 105 is fixedly connected to a positioning clip 107 on the inner wall of its end near the guide ring 103. The positioning clip 107 has a second conical surface 108 on the side facing the connecting ring 109. The first conical surface 106 serves as a guide, preventing the elastic clips 105 from blocking the end face of the guide ring 103 during movement, allowing the elastic clips 105 to be pressed against the port of the frustum-shaped through hole 104 through the first conical surface 106, thereby... The elastic clip 105 can be smoothly inserted into the frustum through hole 104 during movement. The positioning clip 107 increases the thickness of the end of the elastic clip 105, so that when the ends of multiple elastic clips 105 come together, they can enhance the squeezing effect on the outer wall of the cable, thereby enhancing the stability of the cable clamping and fixing. The second conical surface 108 on the positioning clip 107 can guide the cable when it is threaded in the power protection pipe 100, and prevent the cable from being blocked when it comes into contact with the end face of the positioning clip 107, thus affecting the normal threading of the cable in the power protection pipe 100.

[0026] Furthermore, a movable component is movably provided at the port of the power protection pipe 100. This movable component drives the connecting ring 109 to move axially along the power protection pipe 100. The movable component includes an external threaded groove 101 and an end cap 102. The external threaded groove 101 is formed at the end of the outer wall of the power protection pipe 100. The inner wall of the end cap 102 has a threaded groove adapted to the external threaded groove 101. The side of the end cap 102 facing the power protection pipe 100 is fixedly connected to the connecting ring 109. The external threaded groove 101 at the end of the outer wall of the power protection pipe 100, in conjunction with the end cap 102, facilitates the movement of the connecting ring 109. The threaded connection between the end cap 102 and the external threaded groove 101 of the power protection pipe 100 allows the end cap 102 to rotate at the outer end of the power protection pipe 100 using the threaded compression effect. This allows the end cap 102 to move towards the other end of the power protection pipe 100 during clockwise rotation, thereby generating a thrust on the connecting ring 109. At the same time, it can also lock the position of the connecting ring 109, preventing the pressure between the positioning clamp 107 and the cable from driving the connecting ring 109 backward and causing the multiple elastic clamps 105 to loosen, thus maintaining the stability of the cable clamping.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
