[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figures 1-4 As shown, this utility model includes a connector body 1, with a nut 2 threadedly connected to the outer end of the connector body 1. The connection end between the nut 2 and the connector body 1 is provided with a pipe 3. The outer end of the pipe 3 is sequentially fitted with a locking ring 4, a flat washer 5 and a sealing ring 6. The sealing ring 6 abuts against the port of the connector body 1, and the locking ring 4 abuts against the inner side wall of the nut 2.

[0022] The connector body 1 has a limiting step 11 inside its port. One end of the pipe 3 abuts against the limiting step 11 to limit the pipe 3. A limiting slope 12 is provided on one side of the limiting step 11.

[0023] The inner wall of the nut 2 has an inner tapered slope 7. The design of the inner tapered slope 7 can cooperate with the outer tapered slope of the locking ring 4 to enhance the locking effect and make the connection between the pipe 3 and the connector body 1 more secure.

[0024] The surface of the locking ring 4 has an opening 8, and the outer wall of the locking ring 4 has a first outer tapered slope 9. The first outer tapered slope 9 abuts against the inner tapered slope 7 to achieve the inward contraction and tightening of the opening 8 to secure the pipe 3.

[0025] The opening 8 of the locking ring 4 is designed such that when the nut 2 is not tightened, the opening 8 is in its natural state, and the locking ring 4 exerts a relatively small constraint on the pipe 3. As the nut 2 is tightened, the interaction between the inner tapered slope 7 and the first outer tapered slope 9 causes the opening 8 of the locking ring 4 to gradually narrow, thereby applying a greater radial pressure to the pipe 3. This design not only ensures that the pipe 3 will not loosen or fall off during use, but also adapts to pipes 3 of different diameters, and has good versatility.

[0026] The sealing ring 6 is made of rubber. The outer wall of the sealing ring 6 has a second outer tapered slope 10. The second outer tapered slope 10 is placed inside the port of the connector body 1 and abuts against the limiting slope 12 to achieve a seal between the pipe 3 and the port of the connector body 1.

[0027] Dynamic changes in the sealing process: As the nut 2 is tightened, the pressure on the sealing ring 6 gradually increases, and its deformation also increases accordingly. This dynamic change ensures that the sealing effect between the sealing ring 6 and the port of the connector body 1 is continuously optimized as the nut 2 is tightened. Finally, when the nut 2 is fully tightened, a tight sealing contact is formed between the sealing ring 6 and the limiting inclined surface 12 inside the port of the connector body 1, effectively preventing liquid or gas from leaking from the connection between the pipe 3 and the connector body 1.

[0028] Working principle:

[0029] During installation, a locking ring 4, a flat washer 5, and a sealing ring 6 are first sequentially fitted onto the outer end of the pipe 3. Then, the pipe 3 is inserted into the connecting end of the connector body 1 and abuts against the limiting step 11 to limit the pipe 3. The second outer tapered inclined surface 10 of the sealing ring 6 initially contacts the inner wall of the port of the connector body 1, but a tight seal has not yet been formed.

[0030] When the nut 2 begins to tighten, the inner tapered slope 7 of the nut 2 comes into contact with the first outer tapered slope 9 of the locking ring 4 and generates a squeezing effect. Since the surface of the locking ring 4 has an opening 8, when squeezed by the inner tapered slope 7, the opening 8 of the locking ring 4 will gradually shrink and tighten. This process causes the locking ring 4 to apply radial pressure to the pipe 3, thereby firmly clamping the pipe 3 in the connection end of the connector body 1.

[0031] During the tightening of nut 2, the second outer tapered slope 10 of sealing ring 6 gradually fits tightly against the inner wall of the port of connector body 1. Sealing ring 6 is made of rubber and has good elasticity and sealing performance. When sealing ring 6 is subjected to pressure from locking ring 4 and nut 2, the rubber sealing ring 6 will undergo elastic deformation, thereby filling the tiny gap between pipe 3 and port of connector body 1 to form a reliable seal.

[0032] Through the above steps, the components of the sealing element work together to achieve a firm connection and reliable seal between the pipe 3 and the connector body 1. Preferably, the connector body 1 of this device includes, but is not limited to, right-angle elbow connectors, straight connectors, tee connectors, etc. The tightening effect of the locking ring 4 ensures the stability of the pipe 3, while the elastic deformation of the sealing ring 6 provides reliable sealing performance. This design not only simplifies the sealing operation and avoids the cumbersome steps of traditionally wrapping PTFE tape, but also significantly improves the reliability and service life of the sealing element.
