Detailed Implementation

[0026] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0027] like Figures 1 to 4 As shown, this utility model provides a rubber ring for easy installation in water supply pipes, comprising an auxiliary installation ring 1, an extension ring 2, and a rubber ring body 3. The auxiliary installation ring 1 is slidably mounted on the water supply pipe 4. The auxiliary installation ring 1 includes an upper ring body 11 and a lower ring body 12; the outer side wall of the upper ring body 11 has a first groove 111, one side of the upper ring body 11 has a first mounting groove 112, and the bottom of the upper ring body 11 has a sliding groove 113. The outer side wall of the lower ring body 12 has a second groove 121 corresponding to the position of the first groove 111, one side of the lower ring body 12 has a second mounting groove 122, and the top of the lower ring body 12 has an integrally formed slider 123, which is slidably mounted in the sliding groove 113; the upper ring body 11 and the lower ring body 12 are spliced ​​together and fitted onto the outside of the water supply pipe 4.

[0028] The extension ring 2 is detachably connected to the auxiliary mounting ring 1. The extension ring 2 is slidably mounted on the water supply pipe 4 and is used to cooperate with the auxiliary mounting ring 1 to install the rubber ring body 3 on the water supply pipe 4. The extension ring 2 includes a first ring body 21 and a second ring body 22. One side of the first ring body 21 is provided with a connecting plate 211, which is inserted into the first mounting groove 112 or the second mounting groove 122. The other side of the first ring body 21 is provided with a protruding ring 212 extending radially therefrom. The second ring body 22 has the same structure as the first ring body 21 and the second ring body 22 is mirror-distributed. After the first ring body 21 and the second ring body 22 are spliced ​​together, they are fitted onto the outside of the water supply pipe 4.

[0029] The rubber ring body 3 is sleeved on the outside of the auxiliary mounting ring 1 and the rubber ring body 3. Furthermore, a sealing ring 31 is integrally formed on the outside of the rubber ring body 3.

[0030] In use, first insert the slider 123 into the slide groove 113 to connect the upper ring 11 and the lower ring 12 into one piece. Then, install the first ring 21 and the second ring 22 into the first mounting groove 112 and the second mounting groove 122 respectively. At this point, the auxiliary mounting ring 1 and the extension ring 2 are assembled. Then, put the rubber ring body 3 over the auxiliary mounting ring 1 and the extension ring 2, and set the protruding ring 212 outside the sealing ring 31. Then, insert one end of the water supply pipe 4 into the extension ring 2 until the rubber ring body 3 slides to the predetermined position. Then, pinch the protruding ring 212 by hand and pull out the first ring 21 (or the second ring 22), and then pull out the second ring 22 (or the first ring 21). At this time, the rubber ring body 3, which was originally in contact with the extension ring 2, comes into contact with the water supply pipe 4. Finally, pull out the upper ring 11 and the lower ring 12. Since the rubber ring body 3 has already come into contact with the water supply pipe 4, the rubber ring body 3 will not shift during the process of pulling out the upper ring 11 and the lower ring 12. During this process, you can also press down on the rubber ring body 3 that was originally in contact with the extension ring 2 to further increase the friction between the rubber ring body 3 and the water supply pipe 4.

[0031] It should be noted that both the auxiliary mounting ring 1 and the upper ring body 11 are made of plastic with a low coefficient of friction and a certain degree of hardness. By setting the first groove 111 and the second groove 121, the contact area between the upper ring body 11 and the lower ring body 12 and the rubber ring body 3 can be effectively reduced, making it easier to pull out the upper ring body 11 and the lower ring body 12.

[0032] Obviously, when installing the auxiliary mounting ring 1, the upper ring 11 can be placed inside the rubber ring body 3 first, and then the lower ring 12 can be placed inside the rubber ring body 3, and the two can be spliced ​​together as one unit. This installation method can effectively solve the technical problem that the rubber ring body 3 is difficult to slide outside the auxiliary mounting ring 1.

[0033] Understandably, neither the auxiliary mounting ring 1 nor the extension ring 2 should be too thick, so as to prevent damage to the elasticity of the rubber ring body 3 and affect its sealing performance.

[0034] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
