[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example: Refer to Appendix Figure 1-4 As shown, a natural gas pipe sealing joint includes a pipe fitting A100, which is connected to a pipe fitting B200 via an elastic ring 110. It also includes a pipe fitting C300 detachably connected to the end of the pipe fitting B200. Specifically, in this application, either pipe fitting A100 or pipe fitting C300 can be selected to maintain connection with the natural gas appliance connector to be installed. In the actual connection process, depending on the actual installation environment, there will be an angle between pipe fitting A100 and pipe fitting C300. Due to the uncertainty, in this application, after fitting A100 or fitting C300 is connected to the inlet of the gas appliance, the connection between the gas appliance and the external gas pipeline can be achieved by utilizing the snap-fit ​​relationship between fitting B200 and fitting C300 through the snap-fit ​​frame 210 and snap-fit ​​block 310. Furthermore, the setting of the elastic ring 110 can ensure a stable connection between fitting A100 and fitting C300 at any angle after the gas appliance is connected.

[0030] As a quick connection method applicable to pipe fittings A100 and C300, this application also includes a snap-fit ​​frame 210 disposed at the end of pipe fitting B200. The snap-fit ​​frame 210 engages with a snap-fit ​​block 310 disposed on the outer wall of pipe fitting C300. In this application, the number of snap-fit ​​frames 210 is consistent with the number of snap-fit ​​blocks 310, and the sizes of the snap-fit ​​frames 210 and snap-fit ​​blocks 310 are compatible. In actual installation, the snap-fit ​​blocks 310 and snap-fit ​​frames 210 need to be installed in a staggered manner. Then, by rotating pipe fitting C300, the snap-fit ​​relationship between the snap-fit ​​blocks 310 and snap-fit ​​frames 210 can be achieved, thus realizing the snap-fit ​​connection between pipe fittings A100 and C300.

[0031] Furthermore, in this application, to ensure the sealing of the connection between pipe fitting B200 and pipe fitting C300, a connector 400 is also included at the end of pipe fitting B200. The connector 400 is used to ensure the sealing between pipe fitting B200 and pipe fitting C300. Multiple magnetic blocks 420 are evenly and uniformly connected in a ring on the outer wall of the connector 400; a magnetic sheet 212 is fixedly disposed on the side wall of the snap-fit ​​frame 210, and the magnetic sheet 212 and the magnetic blocks 420 are magnetically attracted to each other. The magnetic blocks 420 slide in a groove 211 opened on the snap-fit ​​frame 210.

[0032] Specifically, in this application, to ensure the sealing of the connection between pipe fitting B200 and pipe fitting C300, a connector 400 is also provided on one side of pipe fitting B200. A magnetic block 420 is provided on the outer wall of the connector 400. First, when the snap-fit ​​block 310 and the snap-fit ​​frame 210 are installed, the outer wall of the snap-fit ​​block 310 will contact the outer wall of the magnetic block 420, and drive the magnetic block 420 to slide in the slide groove 211. Furthermore, when the magnetic block 420 slides, the connector 400 rotates synchronously. During this process, the snap-fit ​​block 310 and the rubber ring 410 fixedly connected to one side of the connector 400 rotate synchronously. In this way, it is possible to avoid the rubber ring 410 being misaligned in the overlap groove 201 when the pipe fitting C300 and pipe fitting B200 slide relative to each other during the installation process, which would affect the sealing of the subsequent connection.

[0033] Furthermore, after fittings C300 and B200 are installed and the corresponding rubber ring 410 is relatively fixed, the rubber ring 410 and fitting C300 are in close contact. Even further, the rubber ring 410 is adhered to the outer wall of the connector 400, and the outer wall of the rubber ring 410 overlaps with the outer wall of fitting C300. Fitting B200 has an overlap groove 201, and the outer wall of the overlap groove 201 slides against the connector 400. Along the installation direction of the snap-fit ​​block 310, the sliding groove 211 is inclined, and as the snap-fit ​​block 310 slides on the sliding groove 211, the connector 400 gradually approaches fitting C300. It should be noted that, on the one hand, as mentioned above, through the setting of the magnetic block 420 and the sliding fit between the connector 400 and the overlapping groove 201, when the pipe C300 and the pipe B200 are installed, the corresponding magnetic block 420 will slide in the sliding groove 211. In this application, the sliding groove 211 is set with an inclined structure. As the snap-fit ​​block 310 continues to slide in the snap-fit ​​frame 210, the corresponding snap-fit ​​block 310 will move towards the direction closer to the pipe C300. The corresponding rubber ring 410 bonded to the outer wall of the connector 400 will move closer to the position of the pipe C300 to increase the sealing between the pipe B200 and the pipe C300.

[0034] Furthermore, in order to ensure the stability of the snap-fit ​​relationship between the snap-fit ​​block 310 and the snap-fit ​​frame 210, a magnetic sheet 212 is provided on the side wall of the slide groove 211. The magnetic sheet 212 and the magnetic block 420 are magnetically attracted to each other. In actual use, the position of the snap-fit ​​block 310 can be kept relatively fixed, thereby ensuring the stability of the pipe connection.

[0035] Furthermore, this application also includes an annular groove 301 formed at the end of pipe fitting C300. The diameter of the annular groove 301 on the side closer to pipe fitting B200 is smaller than the diameter on the side farther from pipe fitting B200; the rubber ring 410 is interference-fitted with the annular groove 301. As mentioned above, after pipe fitting C300 and pipe fitting B200 are installed, the corresponding rubber ring 410 will move towards pipe fitting C300. After installation, it will extend beyond the mounting plane of pipe fitting B200 and enter the interior position of the annular groove 301 in the mounting surface of pipe fitting C300. In this state, the sealing end face between pipe fitting B200 and pipe fitting C300 is increased, which can effectively improve the sealing effect. At the same time, the corresponding annular groove 301 will also engage the rubber ring 410 to ensure the stability of the connection.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
