Description

Technical Field

[0001] This utility model relates to the field of sealing components, and more specifically, to a deformation-resistant sealing component. Background Technology

[0002] Seals are materials or parts used to prevent fluids or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. Existing seals have certain errors and defects during use, which can easily damage the seals and affect their service life.

[0003] Sealing rings are usually made of natural or synthetic rubber, which have a certain degree of elasticity. Under constant external force, rubber materials will undergo deformation that increases over time, i.e. creep. This is because the molecular chains inside the rubber will slowly slip and shift under the action of force. Long-term compression causes creep to accumulate continuously, eventually causing the sealing ring to be unable to return to its original shape.

[0004] Therefore, a new deformation-resistant seal needs to be designed to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a deformation-resistant seal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A first limiting block and a second limiting block are fixedly mounted on the inner wall of the mounting cavity. A plurality of fixing holes are provided on the inner top wall of the mounting cavity, and a transmission device is provided between the plurality of fixing holes. A second sealing ring is fixedly mounted on the inner wall of the seal body, and a first sealing ring is fixedly mounted on the outer wall of the seal body.

[0008] like Figures 1-4 As shown, the specific implementation method is as follows: by setting up a transmission device, a first limiting block, a second limiting block, a first sealing ring, and a second sealing ring, the transmission device can push the first limiting block and the second limiting block so that the first limiting block and the second limiting block can be respectively positioned between the first sealing ring and the second sealing ring, thereby pushing the first sealing ring and the second sealing ring and providing them with support. This allows the first sealing ring and the second sealing ring to bear the pressure more evenly, reduces local stress concentration, and effectively prevents the deformation of the sealing component body, ensuring the sealing effect.

[0009] In a preferred implementation form, the transmission device comprises a plurality of screw plugs, and the plurality of screw plugs are respectively screwed into corresponding fixed holes, and the bottom ends of the plurality of screw plugs are connected with fixed rings through bearings.

[0010] In a preferred implementation form, the bottom end of the fixed ring is respectively provided with two inclined grooves.

[0011] In a preferred implementation form, the upper end surface of the first limiting block is provided with an inclined surface, and the upper end surface of the second limiting block is provided with an inclined surface.

[0012] In a preferred implementation form, the first sealing ring is located corresponding to the position of the first limiting block.

[0013] In a preferred implementation form, the second sealing ring is located corresponding to the position of the second limiting block.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The utility model discloses a transmission device, first limiting block, second limiting block, first sealing ring, second sealing ring and other devices are set up, and the first limiting block and the second limiting block can be respectively located between the first sealing ring and the second sealing ring by using the transmission device, and then the first sealing ring and the second sealing ring can be pushed, which provides support for the first sealing ring and the second sealing ring, can make the first sealing ring and the second sealing ring can more evenly bear the pressure, reduces the local stress concentration, thereby effectively prevents the deformation of the sealing element body, and ensures the sealing effect.
