DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , 2As shown in Figures 3, 4 and 5, the utility model provides a technical solution: a combined detachable anti-ultraviolet CPVC pipe, comprising: a first pipe 1 and a second pipe 2, both of which are made of CPVC, a connecting ring 6 is movably sleeved at the end of the second pipe 2, an extrusion spring piece 8 is fixedly connected at the end of the connecting ring 6, an extrusion locking tooth 9 is provided on the inner side of the extrusion spring piece 8, the extrusion locking tooth 9 is a conical structure, and an extrusion ring 11 is threadedly connected to the outer side of the connecting ring 6; a second limiting ring 4 threadedly connected to the connecting ring 6 is fixedly connected at the end of the first pipe 1, a matching notch 5 corresponding to the extrusion locking tooth 9 is provided on the outer side of the second limiting ring 4, and when the extrusion ring 11 is screwed to the end, the extrusion ring 11 squeezes the extrusion spring piece 8 and bends and deforms it so that the extrusion locking tooth 9 is stuck at the end of the second limiting ring 4.

[0023] It should be noted that, when the first pipe 1 and the second pipe 2 are combined and assembled, the utility model rotates the connecting ring 6 after the internal extrusion locking teeth 9 of the connecting ring 6 are passed through the matching notch 5, so that the connecting ring 6 is threadedly connected with the second limiting ring 4. After tightening, the extrusion ring 11 is rotated so that the extrusion ring 11 moves toward the direction of the first pipe 1 under the action of the thread. Since the thickness of the connecting ring 6 gradually increases toward the direction of the second pipe 2, the extrusion ring 11 squeezes the extrusion spring piece 8, so that the extrusion spring piece 8 is compressed and deformed inwardly, so that the extrusion locking teeth 9 on the inner side of the extrusion spring piece 8 are stuck on the outer side of the second limiting ring 4, so as to achieve interlocking, connect the first pipe 1 with the second pipe 2, and the extrusion locking teeth make the connection part more secure, reduce accidental leakage caused by unstable connection, thereby enhancing the overall safety of the system, and can achieve rapid installation and disassembly of the pipeline through the thread and the extrusion locking teeth 9, reducing the installation time.

[0024] See also Figure 1 , 2 As shown in Figures 4, a first limiting ring 3 is provided at the end of the second pipe 2, and a baffle ring 7 interlocked with the first limiting ring 3 is provided on one side of the connecting ring 6, and the outer edge of the baffle ring 7 is a polygonal structure.

[0025] It should be noted that, in the utility model, sealing gaskets are bonded to the sides of the first limiting ring 3 and the second limiting ring 4. Under the mutual blocking action of the baffle ring 7 and the first limiting ring 3, the first limiting ring 3 can prevent the connecting ring 6 from sliding from the outside of the second pipe 2, and when the connecting ring 6 is threadedly connected to the second limiting ring 4, the baffle ring 7 can pull the first limiting ring 3 to move toward the second limiting ring 4, thereby realizing the extrusion docking between the first limiting ring 3 and the second limiting ring 4, and realizing the connection and sealing between the two. The polygonal baffle ring 7 can be tightened by corresponding tools to increase the tightness of the connection.

[0026] See also Figure 4As shown, there are multiple extrusion spring pieces 8 and a contraction notch 10 is provided between two adjacent extrusion spring pieces 8. An extrusion bevel block 13 with a right-angled triangle structure is provided on the outer side of the extrusion spring piece 8, and a chamfer is provided at the end of the extrusion ring 11 to cooperate with the extrusion bevel block 13.

[0027] It should be noted that the function of the extrusion spring piece 8 of the utility model is to provide a lasting clamping force by being compressed. Since there are multiple extrusion spring pieces 8, the system can distribute the pressure more evenly, thereby achieving stable fixation and sealing. The shrinkage notch 10 between adjacent spring pieces allows each spring piece to have a certain degree of independence when subjected to force, ensuring the flexibility and adaptability of the entire system. When the extrusion ring 11 rotates or moves, the extrusion bevel block 13 will generate a gradually increasing force and transfer it to the extrusion spring piece 8. The chamfering allows a smooth transition when the extrusion ring 11 contacts the extrusion bevel block 13, which helps to smoothly transfer the force to the spring piece. Under the action of the extrusion bevel block 13, the thickness of the extrusion spring piece 8 gradually increases. The gradual increase can ensure that the spring piece provides sufficient elasticity while maintaining a constant clamping force, thereby avoiding sudden loosening or insufficient clamping force due to changes in the thickness of the spring piece.

[0028] See also Figure 2 , 3 As shown in Figures 4 and 5, a limit baffle 12 is provided at the end of the connecting ring 6.

[0029] It should be noted that the limiting baffle 12 of the utility model is used to prevent the extrusion ring 11 from separating from the connecting ring 6, thereby ensuring the stability of the connecting structure.

[0030] See also Figure 5 As shown, the outer sides of the first pipe 1 and the second pipe 2 are both provided with a protective layer 14 for anti-ultraviolet rays, and the protective layer 14 is made of polyurethane coating.

[0031] It should be noted that the polyurethane of the utility model has excellent UV resistance, and the polyurethane coating is tough, which can provide additional mechanical strength for the pipeline and prevent external physical damage such as scratches and wear. By providing a protective coating for the pipeline, the protective layer can prevent the pipeline surface from being directly exposed to ultraviolet rays and harsh environments, and prevent corrosion, oxidation and aging.
