| titleOfInvention | A vacuum adsorption device |
| abstract | The invention discloses a vacuum adsorption device, comprising: a main body with an air extraction cavity and an adsorption wall, the adsorption wall is provided with a first through hole communicating with the air extraction cavity; The gas is pumped to the outside world; the one-way valve is matched with the first through hole to allow the gas to flow into the suction cavity from the first through hole in one direction; the sealing gasket is provided with a second through hole corresponding to the communication Through holes, one side of the sealing pad is attached to the bottom surface of the adsorption wall, and the other side is provided with at least two sealing cavities, each of which is connected to the air extraction through the corresponding second through hole and the first through hole. The cavity is connected, and when the sealant is adsorbed on the adsorption surface, at least two sealed concave cavities are not connected to each other; the pressure relief mechanism has a pressure relief channel for connecting the sealed concave cavity and the outside world, and can release the pressure at the sealing position Move between positions to open or close the pressure relief channel. The invention can make the adsorption function more reliable, the adsorption can be easily released, the use effect is better, and the structure is simple. |
