Description

An adapter for portable butane gas bombe

The present invention relates to a portable butane gas bomb adapter, and more particularly to a portable butane gas bomb adapter having a double locking structure that prevents the butane gas bomb from easily separating and flowing by external force, Gas bomb adapter.

Today, in order to light, cook or heat in outdoor activities such as camping or fishing, we use various propane or butane gas equipment (burner, stove, heater, lantern, etc.) Propane gas or butane gas, which is a fuel for such propane or butane gas equipment, is pressed into a small metal bomb, and is commercially available for portable use.

Generally, a portable bomb is classified into a nozzle-type bomb, which is largely filled with butane gas, and a screw-type bomb, into which a high-pressure gas (isobutane, propane gas, etc.) is injected, depending on the structure and shape of the nozzle, It can be divided into bombs.

Here, the nozzle type bomb can be used under normal temperature and air pressure conditions, and the screw type bomb can be used under abnormal conditions such as high temperature and desert, such as temperature and air pressure.

In recent years, propane or butane gas equipment which can be used both as a dual use regardless of the type of bomb has been widely used. Mostly, since a valve having a structure for connecting to a screw type bomb is adopted, a nozzle type bomb If you want to connect and use it, you need a separate adapter.

However, since a conventional adapter has a weak coupling force with a nozzle connected to a nozzle of a nozzle type cylinder, there is a problem that gas leaks while being easily separated or moved by an external force in a state where the nozzle is pressed during use.

Accordingly, as shown in FIG. 1 of Korean Patent Publication No. 10-1062377, there is provided a fixing device comprising a fixing part 200 to which a nozzle type cylinder 500 is connected, a fixing cam 200 rotatably mounted on the fixing part 20, And a pair of levers 250 rotatably mounted on both sides of the hinge shaft 200 at both sides of the fixing part 300. The fixing part 200 is inserted into the nozzle part of the nozzle type cylinder 500 When the nozzle type bomb 500 is rotated in the clockwise direction, the fixed cam 300 simultaneously rotates due to contact interference with the nozzle type bomb 500 to rotate the pair of levers 250 about the hinge axis, In this case, a structure has been proposed in which each of the levers 250 is kept in tight contact with the nozzle type cylinder 500.

However, in such a conventional adapter, since the engagement groove having the shape corresponding to the lever 250 must be formed around the inner surface of the nozzle of the nozzle type cylinder 500, a firmly engaged state can be maintained between them, There is a limitation that the versatility and compatibility of the various nozzle type bombs are significantly deteriorated due to the shape characteristics thereof.

A pair of levers 250 symmetrically formed on both sides of the fixing portion 200 when the fixing portion 200 is inserted into the nozzle portion of the nozzle type cylinder 500 are positioned so as to be always perpendicular to the nozzles of the nozzle type cylinder 500 It is difficult to connect and mount the device and it is inconvenient.
