Description

[0001] DESCRIPTION [0002] CONNECTION ADAPTER FOR GAS CONTAINER [

The present invention relates to a gas appliance connection adapter, and more particularly, to a gas appliance such as a torch lamp, in which a gas container such as butane gas is connected, when the adapter is inserted into the gas appliance, So that a complete sealing can be achieved, thereby preventing a safety accident caused by gas leakage.

2. Description of the Related Art [0002] Generally, portable gas containers each having a small size are mounted on various gas appliances which are portable and movable.

Such portable gas containers include butane gas containers, which can be used in ordinary climates in the home or outdoors, and dome-type high-pressure gas containers that can be used in environments where the temperature and pressure are different from those of outdoor environments such as mountain climbing Are produced separately.

In recent years, gas appliances that can be used in combination with each other regardless of the kind of these gas containers have been widely used.

A butane gas container, which is commonly used, has a cylindrical shape with a long length. A thin-shaped injection nozzle serving as a gas supply means is protruded, and the gas passage is opened by pushing the injection nozzle toward the inside of the gas appliance To supply the gas to the connected gas appliance.

Meanwhile, a butane gas container is also connected to a gas appliance such as a torch lamp used in winter season in winter, and a portable gas appliance such as a torch lamp further comprises an adapter for connecting the gas container.

Therefore, in the butane gas container having the injection nozzle having a long and narrow nozzle, the injection nozzle is connected to the lower side of the adapter formed at the lower part of the gas container, then the gas injected from the injection nozzle through the adapter is supplied into the gas container, .

Various types of adapters have been developed to connect the gas container and the gas appliance in such a manner that the gas in the gas container is supplied to the gas appliance.

As an example, Korean Utility Model Laid-Open No. 96-23782 proposes a connection adapter capable of binding with a simple operation while maintaining a better bonding force between the adapter and the butane gas container.

That is, a positioning member, which is inserted into the cutout groove of the butane gas container, is protruded and molded to the lower end side of the connecting body by the structure of the binding means in which the body of the connection adapter is selectively detachably connected to the butane gas container, A plurality of the resilient pieces formed with the engaging jaws engaged with the ring are formed in the holding member so as to be positioned inside the support ring and are fixed to the connecting body on the inner side of the resilient piece and protruded at intervals corresponding to the resilient piece When the cam protrusions are moved to the positions of the cam protrusions, the resilient piece is widened to the outside and the supporting ring is hooked to the engaging jaw.

However, in the related art, the coupling force with a gas container containing a gas such as butane gas is greatly deteriorated, so that the gas container is separated from the adapter during use or the gas supplied from the gas device leaks.

This problem is caused by the fact that the cams and torsion pieces constituting the adapter can not be strongly adhered to the inside of the head portion of the gas container. Thus, when the bonding force between the head portion of the gas container and the adapter deteriorates, A phenomenon that the gas container is shaken on the way occurs and the supplied gas leaks out.

Accordingly, Applicant has disclosed a modified connection adapter for a gas container, which is disclosed in the publication 20-2012-0003815, in which the fastening ribs are vertically projected on both sides, a packing fitting groove is formed, and fixing projections are formed on one side of the fastening ribs A rotary connection port into which a head portion of a gas container constituted by the injection nozzle is inserted and in which two guide projections are projected, an arc-shaped position groove located on the outer surface of the fastening rib of the fastener, Wherein the outer surface side of the rotating binding cam is in close contact with the inner surface side of the head portion of the gas container by surface contact so that the binding force is greatly increased So as to prevent the connected gas container from being separated or shaken from the gas appliance such as the torch lamp And.

The present invention further includes an elastic incision expanding part inside the rotation connection port connected to the gas mechanism, and further includes a guide surface in a packing fixture fitted to the elastic incision expansion part, so that the elastic incision expanding part is expanded along the guide surface, It is an object of the present invention to provide a gas appliance connection adapter capable of improving bonding force with a gas container and greatly improving airtightness by allowing packings coupled to a fixture to spread in four directions.

According to an aspect of the present invention, there is provided a gas appliance connection adapter having a gas appliance connector to which a gas appliance is connected, the adapter having a connection piece formed on a lower surface of the adapter body; Holes positioned between the connecting pieces; Four elastic cut-away portions vertically extending from the connecting pieces and each having a guide piece protruding from one side thereof; Wherein the four elastic incision expanding portions are provided with an abutment surface which is in close contact with the outer surface, a receiving surface which is extended from the abutting surface and in which the guide pieces of the four elastic incision expanding portions are accommodated and an arcuate guiding surface which connects the abutting surface and the receiving surface A fixture; And a packing that is fitted in the packing fixture and is located in a direction outside the guide piece of the four elastic incision expanding portions accommodated in the receiving surface of the packing fixture.

When the gas container is rotated in one direction with the gas container coupled to the adapter body, four elastic incision expanding portions are expanded to expand the packing in four directions, thereby greatly increasing the coupling force between the gas container and the adapter. It is possible to prevent a safety accident by preventing it from being separated or shaking from a gas appliance such as a torch lamp.
