[0026] The inner wall of the groove 451 is provided with a spring B5, one end of the spring B5 is provided with a polyurethane block 51, one side of the polyurethane block 51 is in contact with one side of the rubber ring 49, the reset directions of the spring B5 and the spring A 47 are opposite, the polyurethane block 51 is in contact with the rubber ring 49 under the action of the spring B5, and the elastic deformation of the spring A 47 and the spring B5, so that the sealing of the connection is better maintained in different pressure environments.

[0027] One side of the rubber ring 49 is provided with a handle 491, so as to adjust the position of the rubber ring 49 through the handle 491.

[0028] One end of the pipeline 2 and the connecting pipe 3 is provided with an elastic sealing ring 6, the elastic sealing ring 6 is a member made of nitrile rubber, the nitrile rubber has the characteristics of oil resistance and wear resistance, and can not only provide additional sealing protection, but also compensate for the possible slight looseness or insufficient sealing of the connecting assembly 4.

[0029] One side of the mounting ring A41 and the mounting ring B42 is provided with a metal sealing gasket 7, the metal sealing gasket 7 can provide more reliable sealing effect, especially when bearing high pressure, can prevent water from leaking from the connection between the mounting ring A41 and the mounting ring B42, and enhance the sealing of the whole connecting structure.

[0030] The outer surfaces of the mounting ring A41 and the mounting ring B42 are provided with rust-proof layers 8, which are components made of galvanization, reducing the risk of damage to the connecting structure caused by rusting of the mounting ring A41 and the mounting ring B42, and ensuring long-term stability of the connecting structure.

[0031] The interiors of the pipe 2 and the connecting pipe 3 are provided with stop valves 9, which cut off water flow, further facilitating installation and disassembly.

[0032] Specifically, first, the mounting ring A41 is firmly fixed on the outer surface of the pipeline 2, and the mounting ring B42 is also fixed on the outer surface of the connecting pipe 3. At this time, the locking screw 43 inside the mounting ring A41 is in a rotatable state, and the locking cylinder 44 inside the mounting ring B42 is ready to cooperate with the locking screw 43. Then, by rotating the locking screw 43, it is screwed into the locking cylinder 44 in the mounting ring B42, so that the mounting ring A41 and the mounting ring B42 are preliminarily connected. Then, through the limiting ring 45 on the outer surface of the mounting ring A41, the displacement of the mounting ring A41 and the mounting ring B42 is effectively limited, preventing them from sliding or deviating relative to each other when subjected to external forces such as water flow impact, vibration, etc., thereby further ensuring the stability and reliability of the connection between the pipeline 2 and the connecting pipe 3. At the same time, the spring A47 in the support block 46 is in a compressed state, and the support rod 48 at one end of the spring A47 exerts a continuous pressure on the rubber ring 49, making the rubber ring 49 tightly fit on one side of the mounting ring B42. Not only does it play a sealing role to prevent water leakage at the connection, but it also to some extent can buffer the impact on the connection caused by vibration or water flow fluctuation, further enhancing the stability and durability of the connection. At the same time, the polyurethane block 51 contacts the rubber ring 49 under the action of the spring B5, and through the elastic deformation of the spring A47 and the spring B5, the sealing of the connection is better maintained in different pressure environments. Since the polyurethane block 51 has a certain elasticity, it will not hinder the mounting ring B42 from entering the groove 451. During the above process, the position of the rubber ring 49 can be adjusted by the handle 491 on one side of the rubber ring 49. In addition, since the pipeline 2 and the connecting pipe 3 are each provided with an elastic sealing ring 6 made of nitrile rubber, which has the characteristics of oil resistance and wear resistance, it not only provides additional sealing protection, but also compensates for the possible slight looseness or insufficient sealing of the connecting assembly 4. In addition, one side of the mounting ring A41 and the mounting ring B42 is provided with a metal sealing gasket 7, which can provide more reliable sealing effect, especially when subjected to high pressure, preventing water from leaking from the connection between the mounting ring A41 and the mounting ring B42, thereby enhancing the sealing of the entire connection structure. Because the outer surfaces of the mounting ring A41 and the mounting ring B42 are provided with a rust-proof layer 8 made of zinc plating, the risk of damage to the connection structure caused by rusting of the mounting ring A41 and the mounting ring B42 is reduced, ensuring the long-term stability of the connection structure. Finally, since the pipeline 2 and the connecting pipe 3 are each provided with a stop valve 9, the water flow can be cut off by the stop valve 9, which is further conducive to installation and disassembly.
