Air bag sealing plug

Technical Field

The invention relates to a bottle stopper, in particular to an air bag sealing plug.

Background

The bottle and can containers are widely used in daily life, the containers can be sealed without opening the bottle stopper, and the structure and the quality of the bottle stopper are related to whether the substances in the containers can be stored for a long time or not. In order to obtain a better sealing performance of the bottle mouth, there has been developed an expandable bottle stopper (No. 101372274) comprising a body member, an elastic member, and a moving member which is movable longitudinally with respect to the body member, wherein the moving member is adapted to move longitudinally with respect to the body member in a first stage to expand longitudinally the elastic member so as to be firmly attached to the inner wall of the opening of the container, and the moving member is adapted to move longitudinally with respect to the body member in a second stage to contract radially the elastic member so as to allow the bottle stopper to be easily removed from the opening of the container. When the material that appears in the bottle in daily life need remain and continue to use next time, or when empty bottle utilized as the secondary, because of this bottle plug is disposable, the sealed bottle plug that has lost former adaptation of this bottleneck, need look for other bottle plugs and replace, but other bottle plugs do not necessarily just adapt to this bottleneck, consequently are difficult to guarantee that this bottleneck reaches better sealed effect to object quality in the bottle has been influenced.

In order to achieve the purpose, the technical scheme adopted by the invention for solving the technical problem is as follows: an air bag sealing plug comprises an outer shell, a clamping mechanism, an air pressure mechanism and an air bag frame, wherein a bottle mouth accommodating groove which is recessed inwards is arranged at the center of the lower end face of the outer shell, a port extends outwards from a through hole at the bottom of the accommodating groove, an air nozzle of the air bag frame is inserted into an air bag port, the edge of the air bag port is clamped in a clamping groove of the air bag frame by a clamping ring at the outer edge, the air nozzle is in threaded connection with the port, a driving disc of the clamping mechanism is sleeved on the outer wall of an inward-protruding accommodating groove, one end of three clamping jaws which are arranged circumferentially is clamped with the driving disc, the other end of the three clamping jaws stretches into a leading-out hole at the side wall of the accommodating groove, a positioning guide pin is arranged in a guiding groove of the driving disc after being in penetrating connection with the clamping jaw, a clamping column of a push rod is connected with the driving disc, a button of the push rod extends out of the outer shell, the two ends of, and form the air seal with the gasbag, inflate the top of the piece and be connected with the clamp plate, the clamp plate loose joint lock catch spare, the lock catch spare rotates and blocks with the latch joint of shell body upper portion inner wall.

The inflatable member is cylindrical, and the peripheral wall of the inflatable member is in a telescopic corrugated shape.

And a sealing ring is arranged on the periphery of the interface at the bottom of the accommodating groove.

The three clamping jaws are arranged in the same circumference, and the top surfaces of the clamping ends of the clamping jaws are in a tooth shape.

After the structure is adopted, the air bag is promoted to expand in unequal amount through the airflow change of the air pressure mechanism, so that the bottle opening is sealed. The gas flow direction of the air bag is regulated and controlled by an inflating part of the air pressure mechanism, and the inflating part and the air bag are hermetically sealed. Compressing the inflating part to increase the volume of the air bag and generate unequal expansion, wherein the expansion size of the volume of the air bag is controlled by the compressed distance of the inflating part; the inflatable piece is stretched, the volume of the air bag is reduced, and the air bag can be conveniently taken out of or put into the bottle mouth. The air bag frame has the advantages that the air bag is fixed by the air bag frame, the air bag frame is convenient to disassemble, the air bag is convenient to replace, and the air seal between the air bag frame and the inflatable part is kept through the sealing ring on the periphery of the interface. The clamping jaw of the clamping mechanism is telescopic and can clamp and connect bottle openings with different sizes, and the clamping jaw enables the bottle plug to be firmly connected with the bottle openings under the action of the elastic ring, so that the air bag is not easy to pull out after the bottle openings are blocked by the air bag. When using, connect the button of pressing the push rod, the push rod drives the driving-disc rotation, makes the inside retraction of jack catch on the bottleneck storage tank lateral wall, and the jack catch is convenient for the bottleneck after the retraction puts into the storage tank in, and the piece that inflates simultaneously is tensile back, and the air current flow in the gasbag makes the volume of gasbag reduce in the piece that inflates, and easy gasbag is plugged in the bottleneck. When the bottle mouth is placed in the containing groove, the connecting button is released, the driving disc rotates under the action of the elastic ring, the clamping claw extends outwards to clamp the bottle mouth, and the bottle plug is fixed on the bottle mouth and is not easy to separate from the bottle mouth. Pressing the inflatable piece, the air current makes the volume increase of gasbag, produces the radial expansion of inequality, firmly blocks up the bottleneck, makes the bottleneck obtain sealed, rotates the latch joint of hasp spare and shell body inner wall, pins the stretching of inflatable piece to make the atmospheric pressure in the gasbag remain stable, the bottleneck obtains sealed for a long time. The invention is suitable for bottle mouths with various sizes and different shapes, and has convenient use and strong sealing property.
