[0005] (II) Technical solution

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0007] A novel silicone sealing ring comprises a sealing outer ring and a sealing inner ring, wherein the inner wall of the sealing outer ring is provided with an annular connecting groove, the outer wall of the sealing inner ring is provided with an annular protrusion corresponding to the annular connecting groove, and the inner wall of the sealing inner ring is also provided with the annular connecting groove.

[0008] Preferably, the longitudinal section of the annular connecting groove is spherical, and the opening of the annular connecting groove is constricted.

[0009] Preferably, the sealing inner ring is provided in plurality, and any two of the sealing inner rings are connected via the annular connecting groove and the corresponding annular protrusion.

[0010] Preferably, it further comprises a closed inner ring, the outer wall of which is provided with the annular protrusion.

[0011] Preferably, the sealing outer ring, the sealing inner ring and the closed inner ring are all made of silicone rings.

[0012] (III) Beneficial effects

[0013] The beneficial effect of the utility model is that: by adopting the above technical scheme, the sealing outer ring can be used alone, and the setting of the annular connecting groove can make the sealing outer ring easier to be extruded and deformed during installation. The sealing inner ring is installed on the inner wall of the sealing outer ring through the annular protrusion, which increases the overall thickness of the sealing ring, improves the compression and rebound amount of the sealing ring, and thus improves the sealing performance of the sealing ring.

[0024] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1 to Figure 2 The utility model provides a new type of silicone sealing ring, including a sealing outer ring 1 and a sealing inner ring 2. The inner wall of the sealing outer ring 1 is provided with an annular connecting groove 3, the outer wall of the sealing inner ring 2 is provided with an annular protrusion 4 corresponding to the annular connecting groove 3, and the inner wall of the sealing inner ring 2 is also provided with an annular connecting groove 3;

[0026] When in use, the sealing outer ring 1 can be used alone. The setting of the annular connecting groove 3 can make the sealing outer ring 1 easier to extrude and deform during installation. The sealing inner ring 2 is installed on the inner wall of the sealing outer ring 1 through the annular protrusion 4, which increases the overall thickness of the sealing ring, increases the compression and rebound amount of the sealing ring, and thus improves the sealing performance of the sealing ring.

[0027] In this embodiment, the longitudinal section of the annular connecting groove 3 is spherical, and the opening of the annular connecting groove 3 is tapered. When in use, the annular protrusion 4 enters the annular connecting groove 3. The annular connecting groove 3 with a spherical longitudinal section not only has strong sealing performance, but also makes the sealing inner ring 2 not easy to fall off.

[0028] refer to Figure 3 , the second embodiment of the utility model:

[0029] In this embodiment, a plurality of sealing inner rings 2 are provided, and two sealing inner rings 2 are connected via annular connecting grooves 3 and corresponding annular protrusions 4;

[0030] The arrangement of multiple sealing inner rings 2 can flexibly adjust the overall thickness of the sealing ring according to actual needs. It is convenient and flexible to use and is suitable for large-scale promotion and use.

[0031] refer to Figure 4 , the third embodiment of the utility model:

[0032] In this embodiment, a closed inner ring 5 is also included, and the outer wall of the closed inner ring 5 is provided with an annular protrusion 4; the closed inner ring 5 can be used to seal the innermost annular connecting groove 3 of the sealing ring, thereby preventing water or other liquids from entering the annular connecting groove 3 and affecting the sealing effect.

[0033] In this embodiment, the sealing outer ring 1, the sealing inner ring 2 and the closed inner ring 5 are all made of silicone rings.

[0034] The working principle of the utility model is as follows:

[0035] The sealing outer ring 1 can be used alone. The setting of the annular connecting groove 3 can make the sealing outer ring 1 easier to be extruded and deformed during installation. The sealing inner ring 2 is installed on the inner wall of the sealing outer ring 1 through the annular protrusion 4, which increases the overall thickness of the sealing ring, improves the compression and rebound amount of the sealing ring, and thus improves the sealing performance of the sealing ring.

[0036] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

[0037] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
