[0013] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0014] Example 1: This embodiment provides a quick-connect fitting for gas pipes, including: The connector 1 is provided with a seat body 11, a threaded connector 12 and a threaded interface. A gas passage is provided inside the seat body 11 to connect the threaded connector 12 and the threaded interface. A stepped structure 14 is provided inside the port of the threaded connector 12. The connecting component 2 includes a rubber pad 21, a gasket 22, a retaining ring 23, and a nut 24. The gasket 22 is disposed on the stepped structure 14. The rubber pad 21 is limited and fitted on the outside of the gasket 22. The retaining ring 23 is disposed on the outside of the rubber pad 21. After the nut 24 is connected to the threaded joint 12, the retaining ring 23 presses the rubber ring tightly against the stepped structure 14. A insertion groove 3 is formed between the rubber pad 21 and the retaining ring 23, which is used to assemble the external gas pipe 10.

[0015] As can be seen from this embodiment, a quick-connect fitting for gas pipes includes a fitting seat 1, a connecting component 2, and a fixing gasket 22; The connector 1 includes a seat body 11, a threaded connector 12 and a threaded interface. The threaded connector 12 and the threaded interface are formed at right angles on the seat body 11, and a gas passage is formed inside the seat body 11 to communicate with the threaded connector 12 and the threaded interface. Furthermore, the connector seat 1 is integrally cast, resulting in high overall structural strength, convenient casting, and low cost. Furthermore, a stepped structure 14 is formed inside the threaded connector 12 port by milling or integral casting mold, and the stepped structure 14 is used to cooperate with the connecting component 2 for installation.

[0016] The connecting assembly 2 includes a rubber pad 21, a gasket 22, a retaining ring 23, and a nut 24. The gasket 22 is connected to the gas passage from the port of the threaded connector 12 and abuts against the stepped structure 14. Similarly, the rubber pad 21 is installed into the gas passage from the port and abuts against the outside of the gasket 22, and is thus limited and fixed on the port portion of the threaded connector 12. After the retaining ring 23 is placed on the outside of the rubber pad 21, the nut 24 is threaded together with the threaded connector 12. During the engagement of the nut 24 with the threaded connector 12, the nut 24 squeezes the retaining ring 23 and the retaining ring 23 tightly abuts and fixes the rubber pad 21 to the threaded connector 12. Furthermore, after the retaining ring 23 and the rubber pad 21 are engaged, a insertion groove 3 will be formed between the retaining ring 23 and the rubber pad 21. In use, the nut 24 and the retaining ring 23 are separated from the threaded connector 12 in sequence and then put on the gas pipe 10. Then the gas pipe 10 is connected to the outside of the rubber pad 21, and the retaining ring 23 and the nut 24 are engaged with the gas pipe 10 in sequence to achieve fixation.

[0017] The overall structure is simple, making it easy to assemble and manufacture, and the connection method of the gas pipe 10 is convenient and easy to use.

[0018] Example 2: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0019] A first slot 4 is provided on the side wall of the stepped structure 14, and a second slot 5 is provided on the rubber pad 21 corresponding to the first slot 4; Among them, the gasket 22 is connected between the first slot 4 and the second slot 5.

[0020] As can be seen from this embodiment, a first slot 4 is opened on the side wall of the step structure 14, and a second slot 5 is correspondingly opened on the side wall of the rubber pad 21; During use, the gasket 22 is inserted into the first slot 4 and the second slot 5, thereby fixing the rubber gasket 21 to the connector seat 1, thus preventing it from falling off during the insertion and removal of the gas pipe 10, and helping to improve the structural strength.

[0021] Example 3: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] Washer 22 is spring washer 22.

[0023] As can be seen from this embodiment, by using the spring washer 22, the ease of assembly between the washer 22 and the first slot 4 and the second slot 5 can be improved by utilizing the deformation capability of the spring washer 22 during use.

[0024] Example 4: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] The front end of the rubber pad 21 is tapered and configured as a cone head 211, and the rear end of the rubber pad 21 is provided with a limiting edge 212; The second slot 5 is formed between the cone-shaped part 211 and the limiting edge 212.

[0026] As can be seen from this embodiment, the rubber pad 21 includes a cone-shaped portion 211 and a limiting edge 212, and the second slot 5 is formed on the cone-shaped portion 211 and the limiting edge 212; The cone-shaped part 211 is formed at the front end of the overall structure of the rubber pad 21. The design of the cone-shaped part 211 makes it convenient for the rubber pad 21 to be connected to the threaded connector 12 during use, and the cone surface is easy to snap into the gas passage. The limiting edge 212 abuts against the gasket 22. The diameter of the rubber gasket 21 at the limiting edge 212 is much larger than the diameter of the gas passage port at the step structure 14, thus forming a limit with the step structure 14, which facilitates assembly.

[0027] Example 5: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0028] The cone-shaped part 211 is tightly fitted to the inner wall of the threaded joint 12 on the inner side of the stepped structure 14.

[0029] As can be seen from this embodiment, the cone-shaped part 211 forms an interference fit with the gas passage, which helps to improve the sealing effect.

[0030] Example 6: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] Multiple annular protrusions 6 are equidistantly arranged on the outer circumferential surface of the cone-shaped part 211; Among them, multiple protruding structures 6 are tightly fitted together with the gas passage wall.

[0032] As can be seen from this embodiment, multiple annular protrusions 6 form a multi-segment sealing structure between the outer peripheral surface of the cone portion 211 and the gas passage, which helps to enhance the sealing effect.

[0033] Example 7: This embodiment provides a quick-connect fitting for gas pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] A boss 7 is provided on the bottom end face of the limiting edge 212, and a groove 8 is provided on the retaining ring 23 corresponding to the boss 7.

[0035] As can be seen from this embodiment, the insertion and extraction of the boss 7 and the groove 8 helps to fix and position the rubber pad 21 and the retaining ring 23, thereby helping to improve assembly efficiency.

[0036] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
