Detailed Implementation

[0014] 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.

[0015] Reference Figures 1-4 A pipe fitting structure includes a connector 2 and a pressure cap 3. The connector 2 has a snap-fit ​​part 5 and a plug-in part 9. The pressure cap 3 is snapped into the snap-fit ​​part 5. The pipe fitting 4 is sleeved on the outer periphery of the plug-in part 9, and the pipe fitting 4 is at least partially interference-clamped between the plug-in part 9 and the inner periphery of the pressure cap 3.

[0016] In one embodiment, the end of the connector 4 that is away from the snap-fit ​​part 5 is fitted onto the connector 9, and the pressure cap 3 passes through the connector 9 and snaps into the snap-fit ​​part 5.

[0017] The connector structure consists of a connector 2 and a pressure cap 3. The connector 2 has a snap-fit ​​part 5 and a plug-in part 9. During installation, the connector 4 is inserted into the plug-in part 9 from the end away from the snap-fit ​​part 5 until it completely covers the outer periphery of the plug-in part 9. Then, the pressure cap 3 is pushed axially to engage and fix it with the snap-fit ​​part 5. During the locking process between the pressure cap 3 and the snap-fit ​​part 5, the outer surface of the connector 4 is pressed inward by the inner peripheral wall of the pressure cap 3, thereby causing at least a partial interference deformation of the connector 4 and firmly clamping it between the plug-in part 9 and the inner peripheral wall of the pressure cap 3, achieving the functions of sealing and preventing detachment.

[0018] The connector structure, through the cooperation of the snap-fit ​​part 5 and the pressure cap 3, locks the connector while using the inner peripheral wall of the pressure cap 3 and the outer peripheral wall of the insertion part 9 to form double-sided compression of the connector 4. Stable fixation and reliable sealing can be achieved without additional fasteners. The structure is simple, the installation is quick, and it can effectively improve the convenience and reliability of water pipe connection.

[0019] The insertion part 9 has a groove structure 11. After the connecting pipe 4 is installed, at least part of the connecting pipe 4 deforms and is embedded in the groove structure 11. The outer peripheral surface of the insertion part 9 is provided with a groove structure 11. After the connecting pipe 4 is fitted and fixed by the pressure cap 3, the inner wall of the connecting pipe 4 is subjected to a pressing force, causing local deformation, so that at least part of it is embedded in the groove structure 11, thereby improving the stability, anti-detachment and sealing performance after connection.

[0020] The latching part 5 has a second protrusion 7, which is at least part of the wall of the groove structure 11, and the end of the pipe to be connected 4 can abut against the second protrusion 7. The latching part 5 is provided with a second protrusion 7, which forms part of the wall of the groove structure 11 and forms a limit in the axial position, so that the end of the pipe to be connected 4 can directly abut against the second protrusion 7 for easy positioning.

[0021] The insertion part 9 has a third protrusion 8 at the end of the groove structure 11 away from the snap-fit ​​part 5. After the pipe 4 is installed, the pipe 4 deforms at the position of the third protrusion 8 and is embedded in the groove structure 11. The third protrusion 8 causes the pipe 4 to deform, improving the anti-detachment property. The third protrusion 8 can be a right-angle structure.

[0022] The end of the plug part 9 has a tapered part 10. The minimum outer diameter of the end of the tapered part 10 is less than or equal to the inner diameter of the pipe to be connected 4, so that the pipe to be connected 4 can be fitted onto the plug part 9. The diameter of the tapered part 10 can be greater than the inner diameter of the pipe to be connected 4.

[0023] The pressure cap 3 includes a ring portion 12 and an inner ring portion 13. The inner peripheral wall of the ring portion 12 has a buckle portion 14, and the snap-fit ​​portion 5 has a first protrusion 6. The buckle portion 14 is snap-fitted to the first protrusion 6; and / or, the connector 4 to be connected is at least partially sandwiched between the outer peripheral wall of the insertion portion 9 and the inner peripheral wall of the inner ring portion 13.

[0024] The pressure cap 3 consists of a ring portion 12 and an inner ring portion 13. The inner circumferential wall of the ring portion 12 is provided with a buckle portion 14, and the snap-fit ​​portion 5 is provided with a first protrusion 6. During installation, the pressure cap 3 is pushed forward axially, so that the buckle portion 14 and the first protrusion 6 are snapped together and locked, thereby fixing the pressure cap 3 to the connector 2. After locking, the inner circumferential wall of the inner ring portion 13 of the pressure cap 3 and the outer circumferential wall of the insertion portion 9 form a clamping space, so that the outer surface of the pipe to be connected 4 is pressed by the inner ring portion 13, and at least part of it is clamped between the insertion portion 9 and the inner ring portion 13, achieving a stable fixation and seal.

[0025] The snap-fit ​​between the inverted part 14 and the first protrusion 6 allows for quick and easy fixing of the pressure cap 3 and the connector 2 without the need for additional tools. This simple structure results in high assembly efficiency. Simultaneously, the inner ring 13's pressing action on the pipe 4 ensures reliable radial clamping, resulting in a stable connection with excellent sealing performance, effectively preventing pipe detachment and leakage.

[0026] The ring portion 12 is provided with several openings 15 spaced apart, so that the ring portion 12 has a certain elastic expansion space, which facilitates the snap-fit ​​operation;

[0027] And / or, the inner peripheral wall of the ring portion 12 has a limiting platform 16, and the distance between the undercut portion 14 and the limiting platform 16 is greater than the axial thickness of the snap-fit ​​portion 5, so as to facilitate the snap-fit ​​portion 14 and the snap-fit ​​portion 5 to be snapped together.

[0028] The inner ring 13 is provided with a reinforcing ring 17, which can be made of stainless steel, for example, to improve the clamping effect.

[0029] A valve body includes the aforementioned connecting pipe structure. The valve body includes a valve body body 1, and the valve body body 1 has a connector 2 located at the inlet end and / or outlet end.

[0030] The valve body 1 has a connector 2 at its inlet or outlet end. In use, the connector 2, in conjunction with the pressure cap 3, the connecting pipe 4, and other components, enables rapid installation and fixation of the water pipe, allowing the valve body 1 to reliably connect to an external water pipe system for liquid input or output. By providing the connector 2 at the inlet and / or outlet end of the valve body 1, the valve body can be directly used with the connecting pipe structure, simplifying the installation process and improving connection stability and sealing performance. This makes it suitable for various liquid transport scenarios, offering convenient installation and strong adaptability.

[0031] As one implementation method, the valve body can be a refrigerator valve, washing machine valve, etc.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
