The invention discloses a general bottle stopper. An internally concave bottle mouth accommodation groove is formed in the lower end surface of a casing of the bottle stopper, a bottle stopper part of an external aerated air bag and an air pressing part of an internal aerated air bag are arranged in a through hole in the bottom part of the accommodation groove, an air flow control piece is arranged on each of two sides of the air pressing part of the aerated air bag, a positioning guide pin I penetrates through and is connected with the air flow control pieces and then the top end of the positioning guide pin is left in a guiding hole of a driving plate, a clamping connection part of each air flow control piece is clamped in a clamping groove of the driving plate, three clamping claws connected through a positioning guide pin II in a penetrating way are arranged on the lower end surface of the driving plate, one end of each clamping claw is in clamped connection with the driving plate and the other locking end of the clamping claw is telescopically arranged in a guiding-out hole formed in the side wall of the accommodation groove, two ends of an elastic ring are fixedly connected to the driving plate and a connecting seat, a push rod drives the driving plate to rotate so that the clamping claws lock the bottle mouth, and simultaneously the air flow control pieces push the air pressing part of the aerated air bag to unequally and radially expand the volume of the bottle plug part of the aerated air bag in the bottle mouth, and therefore the bottle mouth is tightly plugged and sealed. |
