[0001] This utility model relates to the field of sealing ring technology, and in particular to a combined rubber sealing ring. Background Technology

[0002] A rubber sealing ring is a ring-shaped sealing element made of rubber. It is mainly used to prevent fluid or gas leakage and to block foreign objects such as dust and dirt from entering the joints of mechanical equipment, ensuring that the equipment maintains good sealing performance during operation.

[0003] However, in the existing technology, most rubber sealing rings are single ring structures with poor sealing performance, which increases the risk of fluid or gas leakage. Therefore, a combined rubber sealing ring is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined rubber sealing ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a combined rubber sealing ring, including a first anti-detachment ring, a first limiting groove is provided on one side of the first anti-detachment ring, a plurality of threaded holes are provided on one side of the first limiting groove, a rubber gasket is movably connected in the first limiting groove, a second anti-detachment ring is provided on one side of the rubber gasket, a second limiting groove is provided on one side of the second anti-detachment ring, and the other side of the rubber gasket is in contact with one side of the second limiting groove.

[0006] As a further description of the above technical solution:

[0007] Both the first and second anti-detachment rings have an arc-shaped surface on the opposite side, and both are made of ceramic material.

[0008] As a further description of the above technical solution:

[0009] A thickened ring is fixedly connected to one side of the second anti-detachment ring. A plurality of screw holes are provided on one side of the thickened ring, and a countersunk bolt is movably connected through each screw hole.

[0010] As a further description of the above technical solution:

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this combined rubber sealing ring, by setting a first anti-detachment ring, a rubber gasket, a second anti-detachment ring, a thickened ring, and a countersunk bolt, etc., uses a tool to rotate the countersunk bolt. The countersunk bolt drives the first and second anti-detachment rings closer together through the thickened ring, and squeezes the rubber gasket to make the rubber gasket thinner. At the same time, the arc-shaped surfaces of the first and second anti-detachment rings squeeze and push the sealing ring body to the surroundings, increasing the diameter of the sealing ring body. This makes the sealing ring body fit tightly against the inner wall of the pipe, improving the sealing performance of the sealing ring body and reducing the risk of fluid or gas leakage.

[0020] 2. Compared with the existing technology, this combined rubber sealing ring, by setting up magnetic sheets, magnetic blocks and connecting covers, places the connecting cover on one side of the thickened ring, so that the magnetic blocks can be engaged into the corresponding connecting grooves, and the magnetic sheets can be used to fix the magnetic blocks. The connecting cover covers the outside of the thickened ring, which can reduce the probability of external dust, moisture and other contaminants entering the sealing structure, and help extend the service life of the rubber gasket and the sealing ring body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6 The present invention provides a combined rubber sealing ring: including a first anti-detachment ring 1, a first limiting groove 2 is provided on one side of the first anti-detachment ring 1, a plurality of threaded holes 3 are provided on one side of the first limiting groove 2, a rubber gasket 4 is movably connected in the first limiting groove 2, a second anti-detachment ring 5 is provided on one side of the rubber gasket 4, a sealing ring body 6 is attached to the opposite side of the first anti-detachment ring 1 and the second anti-detachment ring 5, and a reinforcing rib 601 is fixedly provided inside the sealing ring body 6. The reinforcing rib 601 keeps the rubber layer of the sealing ring body 6 uniformly deformed and avoids local collapse. A second limiting groove is provided on one side of the second anti-detachment ring 5, and the other side of the rubber gasket 4 is attached to one side of the second limiting groove.

[0031] To improve sealing performance, both the first anti-detachment ring 1 and the second anti-detachment ring 5 have curved surfaces on opposite sides and are made of ceramic material. A thickened ring 7 is fixedly connected to one side of the second anti-detachment ring 5. Multiple screw holes 10 are provided on one side of the thickened ring 7. A countersunk bolt 11 is movably connected through each screw hole 10. One end of each countersunk bolt 11 passes through the second anti-detachment ring 5 and the rubber gasket 4 and is threaded into the corresponding threaded hole 3. By rotating the countersunk bolt 11 with a tool, the countersunk bolt 11 drives the first anti-detachment ring 1 and the second anti-detachment ring 5 closer together through the thickened ring 7, and squeezes the rubber gasket 4 to make it thinner. At the same time, the curved surfaces of the first anti-detachment ring 1 and the second anti-detachment ring 5 squeeze and push the sealing ring body 6 to the surrounding area, increasing the diameter of the sealing ring body 6 and making it fit tightly against the inner wall of the pipe, thereby improving the sealing performance of the sealing ring body 6 and reducing the risk of fluid or gas leakage.

[0032] To extend the service life of the rubber gasket 4 and the sealing ring body 6, multiple connecting grooves 8 are provided on one side of the thickened ring 7. Each connecting groove 8 has a connecting hole on one side, and a magnetic sheet 9 is fixedly connected in each connecting hole. A magnetic block 12 is movably connected in each connecting groove 8. A connecting cover 13 is fixedly connected to one side of the multiple magnetic blocks 12. The connecting cover 13 is placed on one side of the thickened ring 7, so that the magnetic block 12 snaps into the corresponding connecting groove 8, and is fixed by the magnetism of the magnetic sheet 9. The connecting cover 13 covers the outside of the thickened ring 7, which can reduce the probability of external dust, moisture and other contaminants entering the interior of the sealing structure, which is conducive to extending the service life of the rubber gasket 4 and the sealing ring body 6.

[0033] Working principle: By rotating the countersunk bolt 11 with a tool, the countersunk bolt 11 drives the first anti-loosening ring 1 and the second anti-loosening ring 5 to move closer together through the thickened ring 7, and squeezes the rubber gasket 4 to make the rubber gasket 4 thinner. At the same time, the arc-shaped surfaces of the first anti-loosening ring 1 and the second anti-loosening ring 5 squeeze and push the sealing ring body 6 in all directions, increasing the diameter of the sealing ring body 6, so that the sealing ring body 6 fits tightly against the inner wall of the pipe, improving the sealing performance of the sealing ring body 6 and reducing the risk of fluid or gas leakage. Then, the connecting cover 13 is placed on one side of the thickened ring 7, so that the magnetic block 12 is engaged into the corresponding connecting groove 8, and the magnetic sheet 9 fixes the magnetic block 12. The connecting cover 13 covers the outside of the thickened ring 7, which can reduce the probability of external dust, moisture and other contaminants entering the sealing structure, which helps to extend the service life of the rubber gasket 4 and the sealing ring body 6.
