[0007] The fastening mechanism includes a clamping plate and a clamping spring. One end of the two clamping plates is fixedly connected to the inner side of the gasket, and the other end of the two clamping plates is located in the auxiliary lip. The clamping spring is located in the gasket and both ends are connected to the two clamping plates. The two clamping plates are respectively abutted against the two ends of the planar lip.

[0008] Furthermore: O-rings are provided in the corresponding auxiliary lips on the opposite sides of the two clamping plates.

[0009] Furthermore: a limiting plate is provided on one side of the O-ring, and two ends of the limiting plate are respectively connected to the clamping plate and one side of the auxiliary lip.

[0010] Furthermore: the metal reinforcement ring is made of steel.

[0011] Furthermore: a plurality of the clamping springs are located in the washer with equal spacing and are evenly distributed.

[0012] Furthermore: the thickness of the metal reinforcement ring is equal to that of the gasket.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] This patent ensures that the hole sealing ring is not easily deformed under high pressure by providing a metal reinforcement ring. By providing a fastening mechanism, the clamping plate can ensure a tight fit between the auxiliary lip and the sealing hole under the action of the clamping spring, thereby ensuring the sealing effect of the hole sealing ring under high pressure. The patent has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Combined with Figure 1-3The utility model provides a high-pressure resistant hole sealing ring, including a gasket 1, a plane lip 2 and an auxiliary lip 3 are arranged on the outer side of the gasket 1, the two auxiliary lips 3 are located on both sides of the plane lip 2, and a metal reinforcement ring 4 is fixedly connected to the inner side of the gasket 1 to ensure that the hole sealing ring is not easily deformed under high pressure. A fastening mechanism 5 is arranged in the gasket 1, and the fastening mechanism 5 includes a clamping plate 51 and a clamping spring 52. One end of the two clamping plates 51 is fixedly connected to the inner side of the gasket 1, and the other end of the two clamping plates 51 is located in the auxiliary lip 3. The clamping spring 52 is located in the gasket 1 and connected to the two clamping plates 51 at both ends. The two clamping plates 51 are respectively abutted against the two ends of the plane lip 2. When the sealing hole is sealed, the clamping plate 51 ensures that the two auxiliary lips 3 are tightly fitted between the sealing hole from both sides of the sealing hole under the action of the clamping spring 52, thereby ensuring the sealing effect of the hole sealing ring under high pressure.

[0024] Embodiment 2

[0025] Combined with Figure 1-3 On the basis of the first embodiment, an O-ring 31 is provided on the opposite side of the two clamping plates 51 in the corresponding auxiliary lip 3 to ensure the shape of the sealing ring when in use. A limiting plate 32 is provided on one side of the O-ring 31. The two ends of the limiting plate 32 are respectively connected to the clamping plate 51 and one side of the auxiliary lip 3. The limiting plate 32 fixes the O-ring 31 to ensure the overall stability of the auxiliary lip 3 when in use. The metal reinforcement ring 4 is made of steel, which can effectively prevent the sealing ring from being deformed when used in a high-pressure environment. A plurality of clamping springs 52 are located in the gasket 1 with equal spacing and uniform distribution to ensure uniform force on the clamping plate 51. The metal reinforcement ring 4 has the same thickness as the gasket 1, which provides good support for the gasket 1 to prevent its deformation.

[0026] The working principle of the present application is as follows: when using a high-pressure resistant hole sealing ring, the metal reinforcement ring 4 provides good support force for the gasket 1, effectively preventing the sealing ring from deforming when used in a high-pressure environment, and ensuring that the hole sealing ring is not easily deformed under high-pressure conditions. At the same time, the clamping plate 51, under the action of the clamping spring 52, ensures that the two auxiliary lips 3 fit tightly with the sealing hole from both sides of the sealing hole, further ensuring the sealing effect of the hole sealing ring under high-pressure conditions. The structure is simple, easy to install and disassemble, and has a good sealing effect.
