Universal bottle stopper

Abstract

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.

Description

technical field

[0001] The invention relates to a bottle stopper, in particular to a universal bottle stopper. Background technique

[0002] Bottles and cans are widely used in daily life. These containers cannot be sealed without a cork. The structure and quality of the cork are related to whether the contents in the container can be preserved for a long time. In order to obtain a better sealing performance for the bottle mouth, someone invented an expansion-type bottle stopper (Notice No. 101372274). A moving member, the body member can be used for the first section of longitudinal movement, the elastic member is longitudinally expanded, so that it is firmly attached to the inner wall of the container opening, and the body member can be used for the second The longitudinal movement of the section makes the elastic member shrink radially so that the bottle stopper can be easily taken out from the opening of the container. Although this kind of bottle stopper has a good cor...
