[0001] The utility model belongs to the field of automobile accessories and relates to a rubber gasket, in particular to a high-sealing and resilient rubber gasket. Background Art

[0002] Buffer vehicle sealing gaskets are generally installed between two connectors to achieve a sealing effect. However, the current sealing gasket structure is relatively simple and cannot provide efficient sealing properties, which affects the use of connectors. In addition, the elastic force is poor and the rubber gasket is prone to deformation. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art by providing a high sealing and rebound rubber gasket.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A high sealing and rebound rubber gasket, comprising a gasket body, characterized in that an elastic ring groove for facilitating elastic contraction is provided on the outer edge of the gasket body, and a rebound mechanism for improving elastic sealing strength and preventing deformation is provided in the gasket body;

[0005] The gasket body is provided with an installation cavity for installing the rebound mechanism therein;

[0006] The rebound mechanism includes a spring washer located in the installation cavity and used for elastic reset, and a movable part that cooperates with the installation cavity and can move up and down;

[0007] The elastic annular groove has a V-shaped cross section and is arranged on the outer peripheral wall of the gasket body;

[0008] The cross section of the movable part is T-shaped and is movably limited and connected to the gasket body.

[0009] In the above-mentioned high sealing and rebound rubber gasket, the movable part is made of vulcanized silicone rubber or polyurethane rubber material, and the movable part is movably connected to the gasket body and penetrates into the installation cavity, and cooperates with the movable limit of the installation cavity.

[0010] In the above-mentioned high sealing and rebound rubber gasket, the spring gasket is arranged in the installation cavity in a spiral structure, and its two ends respectively abut against the bottom of the movable part and the bottom of the installation cavity.

[0011] In the above-mentioned high sealing and rebound rubber gasket, the gasket body is matched with the elastic ring groove, the movable part and the spring washer structure, so that the gasket body has a high sealing and rebound feature.

[0012] Compared with the existing technology, the high-sealing and high-resilient rubber gasket has a simple structural design. It utilizes the coordination of elastic rings, spring gaskets and movable parts to effectively improve the sealing strength of the gasket body. At the same time, it also improves the elastic strength of the gasket body, realizes the rebound characteristics after deformation, effectively prevents the problem of connection deformation, and greatly improves the applicability.
