Airbag sealing plug

Abstract

The invention discloses an airbag sealing plug. A bottle opening containing groove which is concave inwards is formed in the center of the lower end surface of an outer shell; a connector extends outwards from a through hole in the bottom of the containing groove; an airbag is connected with a nozzle of an airbag rack in a clamped manner; the nozzle is in threaded connection with the connector; one end of each of three clamping claws, which are arranged in the circumferential direction, of a clamping mechanism is connected with a driving disc in a clamped manner; the other buckle ends of the clamping claws extend out of guide holes in the side wall of the containing groove; the clamping claws expand or withdraw when positioning pins connected in a penetration manner slide along guide grooves of the driving disc so as to clamp a bottle opening; a push rod is adopted to drive the driving disc to rotate; the bottom of an inflation component of a pressure mechanism is communicated with the nozzle of the airbag rack and is in air sealing with the airbag. Due to adoption of the inflation component, the airbag is unequally expanded in the radial direction, so that the bottle opening can be solidly blocked and sealed.

Description

technical field [0001] The invention relates to a bottle stopper, in particular to an air bag sealing plug. 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 cork f...

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 cork function, it can only be used for Containers of one specification and caliber are used together and have the characteristics of one-time use

When the substance in the bottle needs to be kept for next use in daily life, or the empty bottle is used for secondary use, because the bottle stopper is for one-time use, the seal of the bottle mouth loses the original matching bottle stopper, and it is necessary to find Other bottle stoppers can be used instead, but other stoppers may not just fit the bottle mouth, so it is difficult to ensure that the bottle mouth achieves a good sealing effect, which affects the quality of the objects in the bottle
