Description

Technical Field

[0001] The utility model relates to the field of sealing rings, in particular to a sealing ring with ribs. Background Art

[0002] A sealing ring is a sealing element installed in a connection or device, usually made of rubber, plastic, metal, or other elastic materials. Its main function is to form a close contact on the sealing surface to prevent fluids, gases, or solid particles from leaking out of the closed system. Sealing rings can be compressed to adapt to different operating conditions such as temperature, pressure, and movement. They are widely used in various industrial fields, including mechanical equipment, automobiles, hydraulic systems, pipelines, valves, etc., to ensure the integrity, safety, and efficient operation of the system.

[0003] Ribbed seals, also known as skeleton seals, are designed to improve sealing performance and enhance structural stability. The ribs increase the seal's contact area and friction with the sealing surface, thereby better resisting leakage under pressure. Ribs also provide additional support, enabling the seal to maintain its shape and performance in high-temperature, high-pressure, or chemical environments, preventing deformation that could lead to seal failure.

[0004] However, when the current sealing rings with ribs are used to connect pipes and rotating shafts, there will be certain errors in the specifications due to the design and production of the pipes and rotating shafts. In addition, the pipes and rotating shafts will also undergo a certain degree of deformation under the influence of changes in ambient temperature. This will cause a gap in the contact between the sealing ring and the rotating shaft during operation, and it is difficult to avoid the leakage of corrosive liquids or gases.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0009] Furthermore, in order to ensure the stability of the rib, the cross section of the rib is L-shaped.

[0010] Furthermore, in order to ensure the sealing effect when the pipeline is connected, the inner sealing ring includes a limiting ring arranged on the inner side of the outer sealing ring and cooperating with the anti-loosening part, an inner sealing ring frame is arranged on the inner side of the limiting ring, and an anti-dust convex ring is arranged on one side of the inner sealing ring frame. A limiting groove that cooperates with the sealing part is opened in the middle position of the inner sealing ring frame.

[0011] Furthermore, in order to make the outer sealing ring close to the inner wall of the pipe, the anti-loosening part includes a number of telescopic rods evenly arranged on the outside of the limiting ring, the outside of the thin rods in the telescopic rods are all provided with springs, and the other ends of the telescopic rods are provided with sealing rings that match the ribs.

[0012] Furthermore, in order to ensure the sealing effect when connecting to the inner wall of the pipe, the outer sealing ring includes an outer sealing ring frame arranged on the outside of the limiting ring, and the inner side of the outer sealing ring frame is provided with a limiting groove 2 that matches the rib, and the outer top and bottom ends of the outer side of the outer sealing ring frame are both provided with rounded corners; the cross-section of the limiting groove 2 is L-shaped.

[0013] The beneficial effects of the utility model are:

[0014] 1. Under the action of the inner sealing ring, ribs and outer sealing ring, the sealing performance of the utility model is improved and the stability of the structure is enhanced. The presence of the ribs can increase the contact area between the inner sealing ring and the outer sealing ring, and increase the friction between the sealing surface in contact with the pipeline and the rotating shaft, so as to better resist leakage when under pressure.

[0024] According to an embodiment of the present utility model, a sealing ring with ribs is provided.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0026] With the help of the above technical solution, the utility model improves the sealing performance of the utility model and enhances the stability of the structure under the action of the inner sealing ring 1, the ribs 3 and the outer sealing ring 4.

[0027] In one embodiment, for the rib 3 , the cross section of the rib 3 is L-shaped, thereby ensuring the stability of the rib 3 .

[0028] In one embodiment, for the above-mentioned inner sealing ring 1, the inner sealing ring 1 includes a limiting ring 101 (the limiting ring 101 is a rubber ring with a certain elasticity) arranged on the inner side of the outer sealing ring 4 and cooperating with the anti-loosening member 2, an inner sealing ring frame 102 is arranged on the inner side of the limiting ring 101, and an anti-ash convex ring 103 (the anti-ash convex ring 103 is a rubber convex ring with a certain elasticity) is arranged on one side of the inner sealing ring frame 102, and a limiting groove 104 cooperating with the sealing member 5 is opened in the middle position of the inner sealing ring frame 102; thereby ensuring the sealing effect when the pipeline is connected.

[0029] In one embodiment, for the above-mentioned anti-loosening part 2, the anti-loosening part 2 includes a plurality of telescopic rods 201 evenly arranged on the outside of the limiting ring 101, and the outer sides of the thin rods in the telescopic rods 201 are each sleeved with a spring 202, and the other ends of the plurality of telescopic rods 201 are provided with a sealing ring 203 that cooperates with the rib 3; thereby, the outer sealing ring 4 can be tightly attached to the inner wall of the pipe.

[0030] The working principle of the anti-loosening part 2 is as follows:

[0031] When the rotating shaft rotates and shakes, the inner sealing ring 1 is in close contact with the rotating shaft through the sealing member 5, which drives the inner sealing ring 1 to shake, so that the telescopic rod 201 in the anti-loosening member 2 is extended or shortened, and the spring 202 in the anti-loosening member 2 is stretched or compressed. The inner sealing ring 1 moves under the cooperation of the limiting ring 101 in the inner sealing ring 1 and the limiting groove 2 402 in the outer sealing ring 4, and under the resetting action of the spring 202 in the anti-loosening member 2, the sealing effect of the shaking rotating shaft is guaranteed.

[0032] In one embodiment, for the above-mentioned outer sealing ring 4, the outer sealing ring 4 includes an outer sealing ring frame 401 arranged on the outside of the limiting ring 101, and the inner side of the outer sealing ring frame 401 is provided with a limiting groove 2 402 that cooperates with the rib 3, and the outer top and bottom ends of the outer sealing ring frame 401 are both provided with rounded corners 403; the cross-section of the limiting groove 2 402 is L-shaped; thereby ensuring the sealing effect when connecting to the inner wall of the pipe.

[0033] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0034] In actual application, when using, first remove the seal 5 that is sleeved on the outside of the limiting groove 104 in the inner sealing ring 1, then pass the rotating shaft through the inner sealing ring 1, and then install the seal 5 to make the inner side of the inner sealing ring 1 in close contact with the outer side of the rotating shaft, and then insert the rotating shaft into the pipe, and the inner wall of the pipe squeezes the outer sealing ring 4. At this time, under the action of the ribs 3, it is ensured that the outer side of the outer sealing ring 4 can be in close contact with the inner wall of the pipe, thereby ensuring the effectiveness of the sealed connection; when the rotating shaft rotates and the rotating shaft shakes, under the action of the anti-loosening part 2, the contact between the sealing ring and the rotating shaft is avoided to form a gap, thereby ensuring the sealing effect.

[0035] The working principle of the anti-loosening member 2 is as described above.

[0036] To sum up, with the help of the above-mentioned technical scheme of the present invention, the present invention improves the sealing performance of the present invention and enhances the stability of the structure under the action of the inner sealing ring 1, the ribs 3 and the outer sealing ring 4. The presence of the ribs 3 can increase the contact area of ​​the inner sealing ring 1 and the outer sealing ring 4, and improve the friction of the sealing surface in contact with the pipeline and the rotating shaft, so that it can better resist leakage when under pressure; under the action of the anti-loosening part 2 and the sealing part 5, the outer sealing ring 4 can be in close contact with the inner wall of the pipeline, so that the inner side of the inner sealing ring 1 can be in close contact with the rotating shaft, and at the same time maintain a certain elasticity when in close contact, and can accept a certain degree of shaking of the rotating shaft while ensuring the sealing effect, thereby avoiding the situation where there is a gap between the contact with the pipeline and the rotating shaft, and improving the effectiveness of the sealing effect.
