[0018] The utility model will be described in detail below in combination with the drawings and specific embodiments.

[0019] The joint device for stretching and straightening flexible pipe provided by the utility model, like Figure 1As shown, the device includes a connecting joint 1, one end of the connecting joint 1 is fixed with a hook unit, the connecting joint 1 is connected with the winch through the hook unit, which is convenient for stretching and straightening. This design makes the operation more simple and efficient, and ensures the safety and stability of the operation; the other end of the connecting joint 1 is provided with a fastening unit on the side wall, and further includes a flexible pipe 3, the flexible pipe 3 is inserted into the connecting joint 1, and the connecting joint 1 and the flexible pipe 3 are fixed through the fastening unit, so as to realize stable connection and prevent displacement or loosening during stretching. This stable connection method not only improves the stretching efficiency, but also effectively reduces the risk of operation failure caused by loose connection. The connecting joint 1 is in a cylindrical structure, and the hook unit is fixed to one end of the connecting joint 1 away from the flexible pipe 3; the hook unit includes three hooks 2, which are arranged on the circumference of the central axis of the connecting joint 1, and the central angles between the three hooks 2 are all 120°. Through the three hooks 2, it is ensured that the tension is along the central axis of the flexible pipe during the lifting and straightening, which ensures the uniform tension, not only improves the stretching efficiency, but also effectively avoids the damage caused by uneven stress. Such design is especially suitable for occasions that require high-precision straightening, which can significantly improve the quality and service life of the flexible pipe. The hook unit includes four bolts 4, which are arranged on the outer wall of the connecting joint 1, and the four bolts 4 penetrate the connecting joint 1, and the four bolts 4 abut against the flexible pipe 3; the four bolts 4 are evenly arranged on the outer wall of the connecting joint 1, and the four bolts 4 are arranged on the same circumference, and the central angles formed by the four bolts 4 are all 90°, which ensures that the flexible pipe is connected with uniform stress, and enhances the stability and safety of the overall structure. In addition, this symmetrical distribution design helps to reduce stress concentration and prolong the service life of the equipment. Four fixed nuts 5 are sleeved on the four bolts 4, and the four fixed nuts 5 are arranged on the outer side of the connecting joint 1, which is convenient for adjustment and maintenance; rubber pads 6 are arranged between one end of the four bolts 4 in the connecting joint 1 and the outer wall of the flexible pipe 3. Through the rubber pads 6, the damage to the flexible pipe during stretching is avoided, and the service life of the flexible pipe is prolonged by replacing the rubber pads 6 at irregular intervals. The selection of rubber pads 6 can be optimized according to the specific material of the flexible pipe to achieve the best protection effect. Figure 2 As shown, four through holes 7 are formed in the outer wall of the connecting joint 1, and the four bolts 4 are arranged one by one in the four through holes 7 on the connecting joint 1.

These features work together to not only improve the stretching and straightening effect, but also greatly improve the safety and convenience of operation.

[0020] The working principle of the joint device for stretching and straightening flexible pipe provided by the utility model is as follows: firstly, the flexible pipe 3 needs to be correctly placed into the connecting joint 1. The connecting joint 1 is specially designed so as to stably accommodate and fix the position of the flexible pipe 3 and ensure that no slippage or misplacement occurs when the stretching operation is performed. Then, the connecting joint 1 and the flexible pipe 3 are tightly connected through the four bolts 4. The bolts not only provide the necessary fastening force, but also ensure that the connection between the two is firm enough during the whole stretching process, thereby avoiding any possible safety hazards or operation failure.

[0021] After that, the whole device is connected with the winch through the three hooks 2. The three hooks are designed to evenly distribute the pulling force, so that the flexible pipe 3 can be subjected to balanced force when being stretched, preventing deformation or other damage caused by uneven force. Each hook must be accurately mounted and ensure that the connection between it and the winch and the connecting joint 1 is safe and reliable.

[0022] Finally, the flexible pipe 3 is subjected to pulling force by operating the winch. The winch serves to provide continuous and stable pulling force, which helps to effectively stretch the flexible pipe to achieve the ideal straight state. During this process, the speed and force of the winch can be adjusted according to actual needs to ensure that the stretching effect is optimal and does not damage the flexible pipe. This straightening process not only improves the appearance of the flexible pipe, but also improves the consistency and strength of its internal structure, prolonging the service life.
