Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a splicable non-metallic gasket. Background Art

[0002] A gasket is a fitting placed between two planes to enhance sealing, which is a sealing element set between static sealing surfaces to prevent fluid leakage. Commonly used gaskets are divided into metal gaskets and non-metallic gaskets. Commonly used non-metallic gaskets include rubber gaskets, polytetrafluoroethylene gaskets, etc.

[0003] At present, existing non-metallic gaskets are often set as splicable for convenient installation. However, during the use of existing splicable gaskets, due to extrusion, the joints are prone to come apart, resulting in the separation of the gasket and unstable structure, thus affecting the use effect of the non-metallic gasket. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that existing non-metallic gaskets are often set as splicable for convenient installation. However, during the use of existing splicable gaskets, due to extrusion, the joints are prone to come apart, resulting in the separation of the gasket and unstable structure, and to propose a splicable non-metallic gasket.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A splicable non-metallic gasket includes a first lower rubber pad and a second lower rubber pad. A first plastic gasket is fixedly connected to the top of the first lower rubber pad, and a first upper rubber pad is fixedly connected to the top of the first plastic gasket. A second plastic gasket is fixedly connected to the top of the second lower rubber pad, and a second upper rubber pad is fixedly connected to the top of the second plastic gasket. One ends of the first upper rubber pad and the second upper rubber pad are integrally formed with blocks, and card holes are formed on one sides of the first lower rubber pad and the second lower rubber pad. The blocks pass through the first plastic gasket and the second plastic gasket and are clamped with the card holes.

[0007] Furthermore, anti-slip grooves are formed on the tops of the first lower rubber pad, the first upper rubber pad, the second lower rubber pad and the second upper rubber pad, and the anti-slip grooves are distributed in an annular array.

[0008] Furthermore, a plurality of anti-slip ridges are integrally formed at one ends of the first plastic gasket and the second plastic gasket, and the anti-slip ridges are located on both sides of the card holes.

[0009] Furthermore, a plurality of anti-slip grooves are formed at one ends of the first upper rubber pad and the second upper rubber pad, and the anti-slip grooves are located on both sides of the blocks.

[0010] Furthermore, the anti-slip ridges and the anti-slip grooves are engaged with each other.

[0011] Furthermore, the cross-sections of the anti-slip ridges are all semi-circular structures.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By bonding a rubber pad and a lower rubber pad on the top of the plastic gasket, and then through the structure of the clamping blocks on both sides being clamped with the special clamping holes, the splicing design is not only convenient for installation but also can keep the connection stable, effectively solving the problem that the connection of traditional spliced gaskets becomes loose due to extrusion during use, and improving the stability and sealing performance of the non-metallic gasket.

[0014] 2. By arranging a plurality of anti-slip ridges at one end of the first plastic gasket and the second plastic gasket, and making these anti-slip ridges engage with a plurality of anti-slip grooves provided on the first upper rubber pad and the second upper rubber pad, the problem of the connection becoming loose due to extrusion is avoided, ensuring a firm connection of the gasket between the static sealing surfaces and further improving the stability of the gasket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1 - 3, A spliceable non-metallic gasket, including a first lower rubber pad 1 and a second lower rubber pad 4. A first plastic gasket 2 is adhesively bonded to the top of the first lower rubber pad 1, and a first upper rubber pad 3 is adhesively bonded to the top of the first plastic gasket 2. A second plastic gasket 5 is adhesively bonded to the top of the second lower rubber pad 4, and a second upper rubber pad 6 is adhesively bonded to the top of the second plastic gasket 5. One end of both the first upper rubber pad 3 and the second upper rubber pad 6 is integrally formed with a clamping block 9. Clamping holes 8 are provided on one side of both the first lower rubber pad 1 and the second lower rubber pad 4. The clamping block 9 passes through the first plastic gasket 2 and the second plastic gasket 5 and is clamped with the clamping hole 8. The structure of the clamping block 9 being clamped with the special clamping hole 8 makes the splicing design convenient for installation and can keep the connection stable, effectively solving the problem that the connection of traditional spliced gaskets becomes loose due to extrusion during use.

[0021] Among them, anti-slip grooves 7 are provided on the tops of the first lower rubber pad 1, the first upper rubber pad 3, the second lower rubber pad 4, and the second upper rubber pad 6. The anti-slip grooves 7 can increase the overall friction of the gasket, and the anti-slip grooves 7 are distributed in an annular array. One end of both the first plastic gasket 2 and the second plastic gasket 5 is integrally formed with a plurality of anti-slip ridges 10, and the anti-slip ridges 10 are located on both sides of the clamping hole 8. A plurality of anti-slip slots 11 are provided at one end of both the first upper rubber pad 3 and the second upper rubber pad 6, and the anti-slip slots 11 are located on both sides of the clamping block 9. The anti-slip ridges 10 and the anti-slip slots 11 are engaged with each other. The anti-slip ridges 10 and the anti-slip slots 11 can prevent the connection from becoming loose due to extrusion, ensuring a firm connection between the gaskets between the static sealing surfaces, further improving the stability of the gasket, and the cross-sections of the anti-slip ridges 10 are all semi-circular structures.

[0022] The working principle of this embodiment: When a non-metallic gasket is needed, the gasket is spliced from both sides of the pipeline or shaft. First, the clamping block 9 is clamped with the clamping hole 8, so as to connect the first lower rubber pad 1, the first plastic gasket 2, the first upper rubber pad 3, the second lower rubber pad 4, the second plastic gasket 5, and the second upper rubber pad 6. Since the clamping block 9 can pass through the first plastic gasket 2 and the second plastic gasket 5, and the anti-slip ridges 10 at one end of the first plastic gasket 2 and the second plastic gasket 5 can be engaged with the anti-slip slots 11 at one end of the first upper rubber pad 3 and the second upper rubber pad 6, the friction at the connection can be increased when the gasket is squeezed, preventing the non-metallic gasket from separating due to extrusion and affecting the use effect of the non-metallic gasket. And the anti-slip grooves 7 can increase the overall friction of the gasket. During the process of tightly clamping the non-metallic gasket, the anti-slip grooves 7 can effectively prevent the gasket from slipping, ensuring its stability and reliability in the working state.

[0023] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
