Sealing gasket

Abstract

The invention relates to a sealing gasket having adsorption force and cushioning action, comprising an installation stem, abdominal walls, an abdominal cavity and wings. The two wings are opened in a zero pressure state, and the abdominal cavity is disposed between the two abdominal walls. When being in compression, the two wings slide towards both sides along the pressure surface of a sealed main body; air in the abdominal cavity is discharged outwards; and the adsorption force is generated. When the pressure of the pressure surface of the sealed main body is maximal, the abdominal walls and the two wings are horizontally paved on the pressure surface and are in maximum contact with the pressure surface, the adsorption force reaches the maximum value, and the sealing gasket is tightly sealed by the sealed main body. The invention has simple structure and wide application ranges and can be used for sealing car doors, doors of planes and ships, household appliances, building doors and windows, domestic through toilet bowls as well as doors, holes, windows, hollows and pipelines of industrial units, for example, when being used for a bamboo steamer in a canteen and a pot cover in a family, the sealing gasket can save fuel in a flat area and prevent half-cooked rice in a plateau section. The invention is more practical and safer than a pressure cooker.

Description

technical field [0001] The invention relates to a sealing pad, in particular to a sealing pad with adsorption force and cushioning effect. Background technique [0002] At present, the doors of refrigerators mostly use flat multi-stack gaskets. This kind of gasket has high hardness and poor elasticity and poor sealing performance. Refrigerators often leak water, and water leakage must also leak air. If the sealing performance is not good, it is the refrigerator. The main reason for electricity consumption. The gaskets used in the doors of automobiles, airplanes and ships have to be "bang" hard to close the door. Although the door is closed, the first damage caused by the confrontation between the action force and the reaction force is the door and the door. Due to poor sealing and other reasons, people change the open-close doors and windows into push-pull doors and windows, but the ventilation area of ​​the push-pull doors and windows is less than 40%. , which requires a ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing gaskets such as poor sealing, poor elasticity, high hardness, easy damage, and troublesome disassembly, the present invention now provides a new type of gasket, which has strong elasticity, good sealing performance, adsorption and buffering effects, and is easy to disassemble.
