Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a self-locking, quick-connecting, leak-proof water pipe joint includes a main pipe 1 and a secondary pipe 2. A positioning ring 11 is fixedly installed on the main pipe 1, and multiple inserts 12 are fixedly installed on one side. A locking ring 23 is fixedly installed on the outer wall of the secondary pipe 2, and the locking ring 23 has slots 24 for inserting the locking inserts 12. A support ring 25 is fixedly installed on the inner wall of the secondary pipe 2, and a rubber ring 5 is fixedly installed on the support ring 25, which abuts against a rubber component 4 fixedly installed at the end of the main pipe 1. By inserting the main pipe 1 and the secondary pipe 2 together, and then using the multiple inserts 12 to insert into the slots 24 on the locking ring 23, a quick locking installation is achieved. At this time, the rubber ring 5 of the support ring 25 and the rubber component 4 on the main pipe 1 abut against each other, thereby further sealing the main pipe 1 and the secondary pipe 2. Compared with a traditional single sealing rubber gasket, the fit and joint deformation of the rubber ring 5 and the rubber component 4 can effectively improve the sealing strength.

[0026] Specifically, the rubber ring 5 and the rubber component 4 are fixedly bonded to the support ring 25 and the main pipe 1 respectively with glue. At the same time, the positioning ring 11 is fixed to the main pipe 1 by welding. Multiple inserts 12 are fixedly installed on the positioning ring 11 by welding. The locking ring 23 and the support ring 25 are fixedly installed on the secondary pipe 2 by welding.

[0027] As a further technical solution provided by this utility model, the rubber part 4 includes an extension 42, and the extension 42 is movably disposed in the side groove 26 opened in the inner wall of the secondary tube 2.

[0028] Specifically, such as Figure 3As shown, when the main pipe 1 and the secondary pipe 2 are connected and assembled, the outer wall of the extension 42 is embedded in the side groove 26, thereby further improving the sealing effect between the main pipe 1 and the secondary pipe 2 while realizing the installation between the main pipe 1 and the secondary pipe 2.

[0029] Furthermore, a recessed portion 43 is provided on the inner side of the extension portion 42, and the flange 51 provided at the end of the rubber ring 5 is movably disposed in the recessed portion 43.

[0030] Specifically, when the main pipe 1 and the secondary pipe 2 are connected by insertion, the flange 51 is embedded in the recess 43, and the fit between the flange 51 and the recess 43 is used to further improve the sealing between the main pipe 1 and the secondary pipe 2. At the same time, the push of the flange 51 against the recess 43 can make the extension 42 more tightly embedded in the side groove 26 to improve the sealing effect.

[0031] Furthermore, the flange 51 is movably mounted on the curved guide portion 41 provided on the rubber part 4.

[0032] Specifically, in order to accurately embed the flange 51 into the recess 43, when the main pipe 1 and the secondary pipe 2 are connected, the flange 51 moves on the curved guide 41. Then, under the curved guide on the curved guide 41, the flange 51 is pushed outward to deform and further embed into the recess 43. At the same time, under the pushing of the curved guide 41, the outward flange 51 further pushes the recess 43, thereby improving the fitting effect of the extension 42 and the side groove 26, and further improving the sealing performance.

[0033] Furthermore, when the flange 51 is located inside the recess 43, the main pipe 1 adheres to the secondary pipe 2 to push the extension 42 to deform and squeeze the flange 51.

[0034] Specifically, when the main pipe 1 and the secondary pipe 2 are inserted together, and the flange 51 is pushed outward and embedded into the recess 43 by the curved guide part 41, as the main pipe 1 and the secondary pipe 2 move closer together, the flange 51 located in the recess 43 is clamped and squeezed by the curved guide part 41 and the extension part 42. Furthermore, under the pressure of the curved guide part 41 and the extension part 42, and the shielding effect of the support ring 25, it... Figure 4 As shown, the rubber ring 5, rubber part 4, flange 51, recess 43, extension 42, side groove 26 and curved guide part 41 fit tightly together, thereby effectively and further improving the sealing performance of the pipe installation.

[0035] Furthermore, a sealing rubber ring 6 is fixedly installed in the groove 27 opened at the end of the secondary pipe 2, and a protruding ring 14 provided at the end of the main pipe 1 is movably disposed in the groove 27.

[0036] Specifically, when the main pipe 1 and the secondary pipe 2 are connected by insertion, the protruding ring 14 at the end of the main pipe 1 is movably positioned in the groove 27 to further seal the two. The protruding ring 14 also compresses the sealing rubber ring 6 to further improve the sealing effect.

[0037] Furthermore, a retaining ring 21 is fixedly installed on the outer wall of the secondary tube 2, and multiple elastic plates 22 are fixedly installed on the retaining ring 21. The ends of the elastic plates 22 are movably disposed in the slots 13 opened on the insert block 12.

[0038] Specifically, the retaining ring 21 is fixedly welded to the outer wall of the secondary pipe 2, and multiple elastic plates 22 are respectively fixedly welded to the retaining ring 21. When the main pipe 1 and the secondary pipe 2 are connected and assembled, multiple insert blocks 12 are respectively inserted into multiple slots 24 on the locking ring 23, and then the ends of the multiple elastic plates 22 are respectively squeezed and embedded in the retaining grooves 13. At this time, multiple elastic plates 22 are used to achieve quick self-locking installation between the main pipe 1 and the secondary pipe 2.

[0039] Furthermore, the push rings 3 fitted on the outer wall of the secondary pipe 2 are movably mounted on multiple elastic plates 22.

[0040] Specifically, when the ends of multiple elastic plates 22 are respectively embedded in the slots 13 to achieve quick self-locking installation between the main pipe 1 and the secondary pipe 2, by fixing the secondary pipe 2 and pulling the push ring 3, the push ring 3 causes the multiple elastic plates 22 to deform, and the ends of the deformed elastic plates 22 disengage from the slots 13, at which point the main pipe 1 and the secondary pipe 2 are quickly unlocked. Thus, this installation method can effectively achieve rapid self-locking and unlocking.

[0041] Furthermore, the elastic plate 22 is an elastic stainless steel plate.

[0042] Furthermore, the push ring 3 is made of stainless steel.

[0043] Working principle: When the main pipe 1 and the secondary pipe 2 are inserted, the flange 51 is pushed outward by the curved guide part 41 and inserted into the recess 43. Then, as the main pipe 1 and the secondary pipe 2 get closer, the flange 51 located in the recess 43 is clamped and squeezed by the curved guide part 41 and the extension part 42. Under the pressure between the curved guide part 41 and the extension part 42 and the shielding of the support ring 25, it is thus... Figure 4As shown, the rubber ring 5, rubber part 4, flange 51, recess 43, extension 42, side groove 26, and curved guide part 41 fit tightly together, thereby effectively and further improving the sealing performance of the pipe installation. At the same time, multiple inserts 12 are respectively inserted into multiple slots 24 on the locking ring 23, and then the ends of multiple elastic plates 22 are respectively squeezed and embedded in the slots 13. At this time, multiple elastic plates 22 are used to achieve quick self-locking installation between the main pipe 1 and the secondary pipe 2.

[0044] Furthermore, when unlocking is required, by fixing the secondary tube 2 and pulling the push ring 3, the push ring 3 causes multiple elastic plates 22 to deform. The ends of the deformed elastic plates 22 disengage from the slots 13, at which point the main tube 1 and the secondary tube 2 are quickly unlocked. Thus, this installation method can effectively achieve rapid self-locking and unlocking.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
