Description

Technical Field

[0002] A silicone gasket disclosed in the patent with the publication number CN219932843U includes a silicone gasket. There are through holes on the upper surface of the silicone gasket, and a buffer device is arranged at the inner top of the silicone gasket. The buffer device includes a spring, a fixed seat, and a support column. A spring is fixedly connected to the inner top of the silicone gasket. The springs are symmetrically arranged above and below the fixed seat. The lower end of the upper spring is fixedly connected to the fixed seat. The lower surface of the fixed seat is fixedly connected to a lower spring. The lower end of the lower spring is fixedly connected to the silicone gasket. The upper surface of the fixed seat is fixedly connected to a buffer column. The buffer columns are symmetrically arranged above and below the fixed seat. Multiple through holes are arranged in a circular array on the upper surface of the silicone gasket, and the through holes penetrate through the silicone gasket.

[0003] By arranging a buffer device composed of a spring, a buffer column, and a fixed seat, it can effectively improve the buffering effect of the silicone gasket, improve the elasticity of the gasket, and reduce the loss of the gasket.

[0004] The technical solution in this comparative document has the effect of improving the elasticity of the gasket, but the defects brought are more obvious. For example, when the silicone gasket is squeezed under high pressure, it will deform, and the deformed silicone gasket will be extruded from the edge of the sealing part, affecting the tightness of the silicone gasket. This solution has a negative impact on the tightness of the silicone gasket. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a silicone gasket with high tightness, which solves the problem that when the silicone gasket is squeezed under high pressure, it will deform, and the deformed silicone gasket will be extruded from the edge of the sealing part, affecting the tightness of the silicone gasket. This solution has a negative impact on the tightness of the silicone gasket.

[0006] To achieve the above object, the utility model provides the following technical solution: A silicone gasket with high tightness includes a silicone gasket. A sleeve hole is opened inside the silicone gasket, and an airbag is sleeved inside the sleeve hole. A sleeve ring for limiting is sleeved on the side of the silicone gasket;

[0007] The inner diameter of the sleeve hole fits the outer diameter of the airbag, and high-pressure gas is arranged inside the airbag. The airbag is sleeved inside the fitting sleeve hole.

[0008] In a specific embodiment, the inner diameter of the sleeve ring fits the outer diameter of the silicone gasket, and the sleeve ring is made of a metal material that can limit the silicone gasket.

[0009] In a specific embodiment, an upper sealant is provided on the top surface of the silicone gasket, and the outer and inner diameters of the upper sealant match those of the silicone gasket.

[0010] In a specific embodiment, a lower sealant is provided on the bottom surface of the silicone gasket, and the outer and inner diameters of the lower sealant match those of the silicone gasket.

[0011] In a specific embodiment, the surface of the silicone gasket is polished to improve the surface flatness and sealing performance, and the silicone gasket is made of an elastic material that is resistant to temperature and chemicals.

[0012] Compared with the prior art, the present utility model provides a silicone gasket with high tightness, having the following beneficial effects:

[0013] In the technical solution disclosed by the present utility model, when the silicone gasket is deformed in the horizontal direction under extrusion, the collar can limit the side surface of the silicone gasket to prevent the silicone gasket from being extruded from the sealing position due to horizontal deformation, which affects the sealing performance of the silicone gasket.

[0014] By filling high-pressure gas into the airbag provided by the present utility model, the airbag is placed inside the sleeve hole inside the silicone gasket. The airbag can increase the toughness of the silicone gasket when it is extruded, preventing excessive deformation. At the same time, the horizontally deformed silicone gasket will be limited by the collar, preventing the silicone gasket from being extruded from the sealing position due to horizontal deformation, which improves the sealing performance of the silicone gasket and prevents the sealing ability from being affected under high pressure.

This solution has a negative impact on the sealing performance of the silicone gasket 1. When the silicone gasket 1 is extruded and deformed in the horizontal direction, the sleeve ring 4 can limit the side of the silicone gasket 1, preventing the silicone gasket 1 from deforming in the horizontal direction and being extruded from the sealing part, thus affecting the sealing performance of the silicone gasket 1.

The airbag 3 is placed inside the sleeve hole 2 inside the silicone gasket 1. The airbag 3 can increase the toughness of the silicone gasket 1 when it is extruded, avoiding excessive deformation. At the same time, the horizontally deformed silicone gasket 1 will be limited by the sleeve ring 4, preventing the silicone gasket 1 from deforming in the horizontal direction and being extruded from the sealing part, playing a role in improving the sealing performance of the silicone gasket 1 and avoiding affecting the sealing ability under high pressure.

[0025] In this specific embodiment, an upper sealant 5 is provided on the top surface of the silicone gasket 1, and the upper sealant 5 fits the inner and outer diameters of the silicone gasket 1; a lower sealant 6 is provided on the bottom surface of the silicone gasket 1, and the lower sealant 6 fits the inner and outer diameters of the silicone gasket 1; the upper sealant 5 and the lower sealant 6 can increase the firmness and sealing performance of the contact between the top and bottom surfaces of the silicone gasket 1 and the sealing part.
