Description

Technical Field

[0001] The utility model relates to the technical field of power protection pipes, and particularly relates to a connection structure of power protection pipes. Background Art

[0002] Power protection pipes, also known as cable protection sleeves or wire protection sleeves, are pipes used for the external protection of electric wires and cables in power engineering. They are mainly used for the insertion and replacement of electric wires and cables, providing protection for electric wires and cables to ensure the safety and stability of power transmission.

[0003] A Chinese patent with the publication number CN216312604U discloses a high-strength power cable protection sleeve, which includes a main protection sleeve and an auxiliary protection sleeve. The main protection sleeve includes a protection sleeve body and a connection device. One end of the protection sleeve body is provided with a connection device. A chute is opened inside the protection sleeve body, and a support frame device is arranged in the chute. The protection sleeve body is composed of a wear-resistant coating, a corrosion-resistant layer, a waterproof layer, a high-strength support base layer, a flame-retardant layer, and a buffer protection layer from the outer layer to the inner layer. One end of the main protection sleeve is connected to the auxiliary protection sleeve through a connection device. The main protection sleeve and the auxiliary protection sleeve have the same structure, solving the problems that in the existing technology, when the power cable protection sleeve is used, it is inevitable to turn, and workers often need to socket a sleeve joint to achieve the turn, which increases the workload and thus reduces the construction speed, and in some cases, the cables inside the protection sleeve are stacked together, causing inconvenience in maintenance.

[0004] As described above, this patent provides a high-strength power cable protection sleeve, which can improve the construction speed and avoid the problem of inconvenient maintenance caused by the stacking of cables inside some protection sleeves. However, it does not have corresponding fixation for the internal cables, and over time, it is inevitable that the cables will be wound together, making it inconvenient for maintenance, and the adaptability in use is not high. Summary of the Utility Model

[0005] The utility model provides a connection structure of power protection pipes to solve the problems raised in the background art.

[0006] To solve the above problems, the utility model provides a connection structure of power protection pipes, which includes a power pipe body, an elastic bending pipe, and a connection assembly. The connection assembly includes a connection sleeve. The two ends of the connection sleeve are respectively threadedly connected to one end of the power pipe body and the elastic bending pipe. A positioning snap ring is fixedly connected inside the connection sleeve. A spring telescopic rod is fixedly connected to the inner surface of the positioning snap ring. One end of the spring telescopic rod away from the positioning snap ring is fixedly connected to an arc-shaped positioning block. A friction pad is sleeved on the surface of the connection sleeve.

[0007] Preferably: one end of the power pipe body is communicated with one end of the elastic bending pipe; one end of the power pipe body is fixedly connected with one end of the elastic bending pipe.

[0008] Preferably: the surface of the connecting sleeve is fixedly connected with the inner wall of the friction pad; a hole positioning disc is fixedly connected to one end of the inner wall of the elastic bending pipe away from the power pipe body.

[0009] Preferably: the number of the spring telescopic rods is set to be multiple, and the multiple spring telescopic rods are circumferentially and uniformly arranged on the inner wall of the positioning snap ring.

[0010] Preferably: protective closing sleeves are threadedly connected to one ends of the power pipe body and the elastic bending pipe respectively; the number of the protective closing sleeves is set to be two.

[0011] The beneficial effects of adopting the above technical solutions are as follows:

[0012] By providing a connecting component, during operation, the cable is passed through the elastic bending pipe into the power pipe body, then passes out from one end of the power pipe body, and then the cable is clamped into the connecting sleeve, and then passes through another elastic bending pipe again. For the cable inside the connecting sleeve, a positioning snap ring is fixed inside the connecting sleeve to connect the spring telescopic rod. After the spring telescopic rod expands and contracts, it drives the arc-shaped positioning block to expand and contract, thereby clamping the cable to achieve the effect of fixing the cable, avoiding the problem that the cables will inevitably be wound together over time, which is not convenient for maintenance, and improving the adaptability of use.

For the cable inside the connection sleeve 3, a positioning snap ring 4 is fixedly arranged inside the connection sleeve 3 for connecting the spring telescopic rod 5. After the spring telescopic rod 5 expands and contracts, it drives the arc-shaped positioning block 6 to expand and contract, thereby clamping the cable and realizing the function of fixing the cable.
