[0037] In the description of the present application, it should be pointed out that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In addition, in the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0039] For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] Please refer to Figures 1-2 The sealing ring for pipe material in the embodiment of the present application comprises a sealing body 1 and an elastic framework 2.

[0041] The sealing ring is annular when installed on the pipe material, and can also be in an unfolded state when the pipe material is not installed.

[0042] Please refer to Figure 3 and Figure 4The elastic framework 2 is arranged inside the sealing body 1, the elastic framework 2 is a spring-shaped winding of strip-shaped metal sheets 21, there is a spacing 22 between the metal sheets 21 of adjacent two turns, and the metal sheets 21 are attached to the sealing body 1.

[0043] The arrangement of the elastic framework 2 can prevent the sealing ring from being too soft and ensure the sealing effect of the sealing ring.

[0044] The elastic framework 2 is a spring-shaped winding of strip-shaped metal sheets 21, the sheet shape of the metal sheets 21 can better attach to the sealing body 1 and is not easy to separate from the sealing body 1. The metal sheets 21 have a certain strength, and after being wound into a spring shape, the metal sheets 21 can provide elasticity and toughness. There is a spacing 22 between the metal sheets 21 of adjacent two turns, the spacing 22 can provide toughness and deformation allowance, and the sealing ring can rebound after deformation to prevent the installation process from affecting the sealing effect of the sealing ring. In addition, the existence of the spacing 22 can better combine the elastic framework 2 with the sealing body 1 and reduce the risk of separation of the metal sheets 21 from the sealing body 1.

[0045] The above structure can facilitate the replacement of the sealing ring on the pipe material, has high toughness, and can ensure the sealing effect after installation.

[0046] In some embodiments, the cross section of the elastic framework 2 is a circular ring. The circular ring can improve the rigidity of the elastic framework 2 and improve the support capacity of the elastic framework 2.

[0047] In some embodiments, the cross section of the metal sheets 21 is a rectangle. After winding, the sheet shape of the metal sheets 21 can better combine with the sealing body 1 and provide a certain support strength.

[0048] In some embodiments, the sealing body 1 is sealing rubber. The sealing rubber has a certain elasticity and has a sealing effect.

[0049] In some embodiments, the metal sheets 21 are steel sheets. In other embodiments, the metal sheets 21 can also be made of other materials, such as copper sheets, aluminum sheets, etc.

[0050] In some embodiments, a cavity 11 is formed inside the sealing body 1, the elastic framework 2 is arranged in the cavity 11, and the metal sheets 21 are attached to the cavity wall of the cavity 11. The sealing body 1 is equivalent to wrapping the outside of the elastic framework 2, so that the elastic framework 2 can be located inside the sealing body 1, and the metal sheets 21 can better attach to the sealing body 1.

[0051] In some embodiments, the winding direction of the metal sheets 21 is counterclockwise around the winding shaft. In the upward direction of the winding shaft, as shown in the view direction of Figure 4 When the metal sheets 21 are wound, they extend from left to right and are wound counterclockwise along the winding shaft.

[0052] In some embodiments, the outer surface of the sealing body 1 has a matching surface 12, which is used to match with the pipe. When the sealing ring is installed on the pipe, the matching surface 12 directly matches with the pipe to ensure the sealing effect.

[0053] The present embodiment also provides a pipe, which comprises a pipe body 3 and the sealing ring as described above, and the pipe body 3 has a groove 31, and at least a part of the sealing ring is detachably arranged in the groove 31.

[0054] The matching surface 12 of the sealing body 1 is located in the groove 31, and when the sealing ring is installed, the sealing ring can be first bent and then placed in the groove 31. Specifically, one part of the sealing ring can be pressed first, and then the other part of the sealing ring can be pressed to ensure that the sealing ring can completely match with the groove wall of the groove 31, and the sealing ring is also fixed in the groove 31.

[0055] In some embodiments, the groove 31 is arranged on at least one end of the pipe body 3, and the groove 31 is located on the inner wall of the pipe body 3. Through such a structure, when the pipe is connected with other pipes, the other pipes can be inserted into the pipe opening of the pipe, and the sealing ring is located between the two pipes to play a sealing role.

[0056] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
