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.
