[0015]

The operation of the present invention will be described below.

The fire extinguisher gas injection device of the present invention is the same as the conventional one in that it uses a cylinder filled with a high pressure extinguishing gas.

Further, when the fire extinguishing gas is injected from the above-mentioned cylinder, cooling heat of about -45 ° C. is generated, the original heat of the combustion product is rapidly cooled to extinguish the cooling, or the liquid filled in the cylinder. Although it depends on the amount of gas, if the distance from the fire is 2 m or less, it can be extinguished by injecting it directly into the fire source even in a large room. Is.

A procedure for loading the cylinder into the cylinder will be described.

First, while pushing the push portion mounted on the hammer operating portion while pulling the operating portion toward the rear portion of the cylindrical body, the scraping portion connected to the hammer portion is proportional to the movement. It moves toward the rear part of the cylinder. At that time, the elasticity interposed between the hammer portion and the rear portion of the cylinder is reduced, and at the same time, the rear end of the hammer stopper is locked with the front end of the hammer, and one end of the trigger is moved upward by a spring. The slide portion is simultaneously pushed upward by this pressure.

When the above conditions are reached,
The fire extinguishing gas is inserted into the cylinder first from the rear of the cylinder filled with high pressure, and the head of the cylinder is also sequentially inserted into the cylinder. When the cylinder is inserted into the cylinder as described above, the slide portion that has been pushed up also pushes the tip portion of the trigger, and the two members become horizontal as shown in the drawing. At that time, the spring attached to the trigger is contracted.

The above is the sequence when one cylinder is inserted into the cylinder.

Next, the sequence of injecting a fire extinguishing gas into a cylinder inserted in the fire extinguishing gas injection device of the present invention will be described.

The user holds the cylinder with his left hand and lifts it, holds the grip with his right hand, and triggers his finger. At that time, one end of the hammer stopper located above the trigger is slightly pushed up, and at the same time, the other end of the hammer stopper is released from the engagement state with the hammer portion, and the hammer portion instantly moves to the elastic body. Move forward by stretching. The hammer that has moved forward strikes the rear part of the front cylinder, the struck cylinder moves forward, the head of the cylinder fits into the recess in the front part of the cylinder, and at the same time, the sealing plate of the cylinder is broken by the firing pin and the fire is extinguished. Gas is injected from the injection hole. At that time, since the packing is coated on the head of the cylinder, it does not leak out to the rear part of the cylinder. The above is the process of injecting the extinguishing gas in the cylinder.

Further, the steps for taking out the cylinder after the extinguishing gas has been injected will be described.

While pressing the tongue piece through the push part attached to the hammer operating part, the operating part is pulled to the rear part of the cylinder. At that time, the elastic body contracts, and the front part of the hammer and the other end of the hammer stopper are locked to prevent the movement of the hammer. Simultaneously with the backward movement of the hammer section, the scraping section also moves backward in proportion, and the scraping section locked at the shoulder of the cylinder at that time moves the cylinder backward. Move in the direction of the part. The cylinder moved as described above is pushed up by the slide portion lifted by the spring attached to the trigger.

The cylinder pushed up as described above is grasped by fingers and taken out from the window hole.

When the cylinder is taken out as described above,
A cylinder filled with a new fire extinguishing gas is inserted into the cylinder by the same operation as the above-described process.

Further, according to the present invention, when the fire extinguishing gas is being injected, the tongue piece and the hammer operating portion are provided even if a large load is applied to the cylinder against the high pressure generated when the high pressure filling fire extinguishing gas is injected. However, since it is locked, the hammer part is moved backward and the cylinder is not suddenly ejected backward.

Further, according to the present invention, since only one cylinder can be inserted into the cylinder, the overall weight is light.

Further, according to the present invention, the slide portion lifted by the trigger has an inclination angle of 90 degrees or less, so that the cylinder can be inserted into and removed from the cylinder very smoothly. .
