Description

Technical Field

[0001] This utility model relates to the field of sponge sealing technology, and in particular to a highly elastic sponge sealing component. Background Technology

[0002] Sponge seals are a type of ring-shaped seal primarily used to form a seal at the joints of connectors, preventing media leakage or the entry of external impurities. Compared to ordinary rubber seals, sponge seals have better elasticity and compressibility, can adapt to different shaped joint surfaces, achieve better sealing effects, ensure the normal operation of mechanical equipment, and have good cushioning performance. They are widely used in various fields such as electronic products, automotive parts, and home appliances.

[0003] However, in the existing technology, when using sponge seals, due to the weak support performance of the sponge itself and the poor linkage support between sponges, the sponge is prone to failure to return to its original state after being compressed for a long time due to its poor elastic recovery force, thus affecting the sealing performance of the sponge seal after long-term compression. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing sponge seal has poor elastic recovery force after long-term compression, resulting in reduced sealing performance, and proposes a highly elastic sponge seal.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: it includes a sponge sealing component body, which comprises a sponge inner liner, an elastic rubber support layer, an elastic sponge support layer, and hollow elastic rubber rings. The outer surface of the sponge inner liner is fixedly fitted with an elastic rubber support layer, the outer surface of the elastic rubber support layer is fixed with an elastic sponge support layer, the outer surface of the elastic sponge support layer is fixed with a flexible rubber outer layer, and a placement groove is formed inside the elastic sponge support layer. Several hollow elastic rubber rings are fixed at equal intervals inside the placement groove.

[0006] Preferably, rubber connecting gaskets are fixed at both the upper and lower ends of the sponge sealing component body, and rigid fixing plates are fixed on the side of the two rubber connecting gaskets away from the sponge sealing component body. The rubber connecting gaskets and rigid fixing plates extend to the outer edge of the sponge sealing component body and are provided with fixing holes at equal intervals.

[0007] Preferably, the rubber connecting gasket and the rigid fixing plate have equal thicknesses, the inner and outer ring diameters of the rubber connecting gasket and the rigid fixing plate are equal, the inner ring diameter of the rubber connecting gasket and the rigid fixing plate is larger than the inner ring diameter of the sponge sealing body, and the outer ring diameter of the rubber connecting gasket and the rigid fixing plate is larger than the diameter of the sponge sealing body.

[0008] Preferably, the thickness of the inner sponge liner is greater than the thickness of the elastic rubber support layer, the thickness of the elastic sponge support layer is greater than the thickness of the inner sponge liner, the thickness of the flexible rubber outer layer is less than the thickness of the elastic rubber support layer, and the thickness of the placement groove is equal to half the thickness of the elastic sponge support layer.

[0009] Preferably, each of the placement slots and hollow elastic rubber rings is configured as annular rings that cooperate with the main body of the sponge seal, and each hollow elastic rubber ring has a rubber sealing sheet with the same thickness as the side wall of the hollow elastic rubber ring embedded inside.

[0010] Preferably, the thickness of each hollow elastic rubber ring is equal to the thickness of the placement groove, and the height inside the placement groove is equal to the sum of the heights of all the hollow elastic rubber rings.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by embedding multiple elastic rubber rings in the elastic sponge support layer, the elastic recovery force of the sponge seal can be increased through the annular elastic rubber rings during use. This solves the problem that the existing sponge seal has poor elastic recovery force after long-term compression, resulting in reduced sealing performance. It ensures that the sponge seal can still maintain sufficient recovery force and sealing performance after being subjected to pressure for a long time.

[0013] 2. In this utility model, by filling the elastic rubber ring with gas, the overall hardness and elasticity of the sponge seal body are controlled. In the sealed state, after the pressure on one side is released, the elastic rubber ring will be restored and evenly expanded under the action of internal air pressure, further ensuring the overall sealing performance of the sponge seal after restoration.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figure 1-3 As shown, this utility model provides a high-elasticity sponge seal, including a sponge seal body 1. Rubber connecting gaskets 2 are fixed to both the upper and lower ends of the sponge seal body 1. Rigid fixing pieces 3 are fixed to the sides of the two rubber connecting gaskets 2 away from the sponge seal body 1. The rubber connecting gaskets 2 and the rigid fixing pieces 3 extend to the outer edge of the sponge seal body 1 and are equidistantly provided with fixing holes. The rubber connecting gaskets 2 and the rigid fixing pieces 3 have equal thicknesses, and their inner and outer diameters are equal. The inner diameter of both the rubber connecting gaskets 2 and the rigid fixing pieces 3 is larger than the inner diameter of the sponge seal body 1, and the outer diameter of both the rubber connecting gaskets 2 and the rigid fixing pieces 3 is larger than the diameter of the sponge seal body 1. The seal is formed by the rubber connecting gaskets... The sheet 2 and the rigid fixing sheet 3 facilitate the fixing of the sponge sealing body 1 to the structure to be sealed. The sponge sealing body 1 includes a sponge inner sleeve 11, an elastic rubber support layer 12, an elastic sponge support layer 13, and hollow elastic rubber rings 16. The elastic rubber support layer 12 is fixedly sleeved on the outer surface of the sponge inner sleeve 11. The elastic sponge support layer 13 is fixed on the outer surface of the elastic rubber support layer 12. A flexible rubber outer layer 14 is fixed on the outer surface of the elastic sponge support layer 13. A placement groove 15 is opened inside the elastic sponge support layer 13. Several hollow elastic rubber rings 16 are fixed at equal intervals inside the placement groove 15. The thickness of each hollow elastic rubber ring 16 is equal to the thickness of the placement groove 15. The height inside the placement groove 15 is equal to the sum of the heights of all the hollow elastic rubber rings 16.

[0021] The specific settings and functions of this embodiment are described below: The thickness of the sponge inner liner 11 is greater than the thickness of the elastic rubber support layer 12, the thickness of the elastic sponge support layer 13 is greater than the thickness of the sponge inner liner 11, the thickness of the flexible rubber outer layer 14 is less than the thickness of the elastic rubber support layer 12, and the thickness of the placement groove 15 is equal to half the thickness of the elastic sponge support layer 13, ensuring that the hollow elastic rubber ring 16 can be wrapped inside the elastic sponge support layer 13. Each placement groove 15 and hollow elastic rubber ring 16 is set as an annular shape that cooperates with the sponge sealing body 1. Each hollow elastic rubber ring 16 has a rubber sealing sheet 17 with the same thickness as the side wall of the hollow elastic rubber ring 16 embedded and fixed inside. Before each hollow elastic rubber ring 16 is fixed inside the placement groove 15, gas is first injected into the hollow elastic rubber ring 16 through the rubber sealing sheet 17 via a needle, and the air pressure inside the hollow elastic rubber ring 16 is controlled according to the overall hardness required by the sponge sealing body 1.

[0022] The overall effect of this embodiment is that the elastic sponge support layer 13 is supported by the elasticity of the hollow elastic ring 16 and the air pressure inside the hollow elastic ring 16. This allows control over the overall hardness and elasticity of the elastic sponge support layer 13. Furthermore, after the pressure is released, the air pressure inside the hollow elastic ring 16 helps the elastic sponge support layer 13 to quickly recover, thereby ensuring the sealing performance of the sponge sealing body 1.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
