TECHNICAL FIELD
[0001] The utility model relates to rubber seal ring field, concretely relates to a rubber seal ring that can prevent falling off. BACKGROUND
[0002] The selection of the seal ring material is important to its sealing performance and service life, and the performance of the material directly affects the service performance of the seal ring. The common seal ring on the market is made of rubber or silica gel. Rubber refers to a high-elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under the action of a small external force. It can restore to its original state after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight of more than several hundred thousand. Therefore, rubber seal ring is the best material for sealing.
[0003] The existing rubber seal ring has a single structure, which is usually a ring structure. Its sealing performance is generally poor. After long-term use, it is severely worn and is prone to falling off, which affects its sealing performance.
[0004] Therefore, the utility model provides a rubber seal ring that can prevent falling off. UTILITY MODEL CONTENT
[0005] In order to overcome the defects in the prior art, the utility model provides a rubber seal ring that can prevent falling off. The seal ring body is limited by the first limiting convex ring, the second limiting convex ring, and the anti-falling arc edge. The seal ring body is locked by the limiting fitting hole to prevent the seal ring body from falling off. Two seal fitting ring grooves are provided to achieve double sealing effect and improve the sealing performance.
[0006] TECHNICAL SCHEME
[0007] A rubber seal ring that can prevent falling off includes a seal ring body. A plurality of annular arrays of anti-falling arc edges are arranged on one side of the seal ring body. A limiting fitting hole is arranged in the anti-falling arc edge. A plurality of concentric seal fitting ring grooves are arranged on the other side of the seal ring body.
[0008] Further, the side of the seal ring body provided with the anti-falling arc edge is also provided with a first limiting convex ring. The first limiting convex ring is close to the outer ring side of the seal ring body.
[0009] Further, the side of the seal ring body provided with the anti-falling arc edge is also provided with a second limiting convex ring. The second limiting convex ring is close to the inner ring side of the seal ring body.
[0010] Further, the seal fitting ring grooves, the first limiting convex ring, the second limiting convex ring, and the anti-falling arc edge are staggered.
[0011] Furthermore, the sealing groove of the inner ring is directly opposite the gap between the anti-detachment arc edge and the first limiting protrusion.
[0012] Furthermore, the sealing groove of the outer ring is directly opposite the gap between the anti-detachment arc edge and the second limiting protrusion.
[0013] Beneficial effects
[0014] Compared with the prior art, this utility model has the following advantages: the sealing ring body is limited by the first limiting protrusion ring, the second limiting protrusion ring, and the anti-dislodgement arc edge; the sealing ring body is locked by the limiting mating hole to prevent the sealing ring body from falling off; and by setting two sealing mating ring grooves, a double sealing effect is achieved, thereby improving the sealing performance.

[0021] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:
[0022] have Figures 1-4 As shown, this utility model discloses a rubber sealing ring that can prevent detachment, including a sealing ring body 1. A plurality of annular array anti-detachment arc edges 4 are provided on one side plane of the sealing ring body 1. Limiting mating holes 6 penetrate through the anti-detachment arc edges 4. A plurality of concentric sealing mating ring grooves 5 are provided on the other side plane of the sealing ring body 1.
[0023] Further, the side of the sealing ring body 1 provided with the anti-arc-off edge 4 is also provided with a first limiting convex ring 3, which is close to the outer ring side of the sealing ring body 1.
[0024] Further, the side of the sealing ring body 1 provided with the anti-arc-off edge 4 is also provided with a second limiting convex ring 2, which is close to the inner ring side of the sealing ring body 1.
[0025] Further, the sealing cooperation ring groove 5, the first limiting convex ring 3, the second limiting convex ring 2, and the anti-arc-off edge 4 are staggered.
[0026] Further, the position of the sealing cooperation ring groove 5 of the inner ring is opposite to the gap between the anti-arc-off edge 4 and the first limiting convex ring 3.
[0027] Further, the position of the sealing cooperation ring groove 5 of the outer ring is opposite to the gap between the anti-arc-off edge 4 and the second limiting convex ring 2.
[0028] Specifically, three ring grooves are arranged on the side end face that needs to be sealed, which are adapted to the anti-arc-off edge 4, the first limiting convex ring 3, and the second limiting convex ring 2, respectively, three limiting arc rods are arranged in the middle ring groove, which are used to adapt to the limiting cooperation hole 6, and two convex rings are arranged on the other side end face, which are used to adapt to the two sealing cooperation ring grooves 5.
[0029] In use, the anti-arc-off edge 4, the first limiting convex ring 3, and the second limiting convex ring 2 are put into the three ring grooves, then the sealing ring body 1 is rotated by sixty degrees, so that the limiting arc rods arranged in the middle ring groove are penetrated into the limiting cooperation hole 6, to form locking, then the two convex rings on the other side end face are pressed on the sealing cooperation ring groove 5, to form a stable sealing effect.
