Description

Gas bullets for gas injectors

The present invention relates to a gas injector, and more particularly, to a gas injection cartridge for a gas injector configured to more reliably and completely inject a gas filled therein.

Conventionally, a gas injector using a tear gas powder or the like (hereinafter referred to as 'gas') was used by filling gas into a single disposable filling container. However, in the case of using the disposable filling container as described above, there was a problem in that a large amount of deterioration occurred when one gas injection could not escape the emergency situation.

Due to this problem, a technique has been developed to improve the gas powder and to fire gas several times by filling the gas powder separately into a plurality of gas bullets. Such a gas bullet is used by being mounted on a magazine of a general reverberant pistol as shown in FIG. 1.

Such a gas bullet is opened and closed at the same time as the valve is opened at the moment of triggering by the impact of the key 4 actuated by the user pulling the trigger 3 and the impact of the gunpowder explosion. There is a problem that only about 30% is injected without all the injection. That is, sufficient time for the gas inside the gas shell to be injected to the outside is not secured so that the gas filled in the gas shell can not be efficiently used.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a gas bullet which is configured to completely inject a filled gas upon triggering.

The tip portion of the nozzle body is formed to be formed inside the magazine of the gas injector so as not to flow in the magazine.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a gas jet for a gas injector according to the present invention as described above will be described in detail.

As shown in FIG. 2, the gas shell 10 of the present embodiment has a space in which gas is filled in the casing 11 constituting its exterior. The gunpowder 13 is provided at the rear of the casing 11 (the part where the knock 4 is impacted when triggered) to play a role of a brain.

In addition, the front of the shell 11 is provided with a configuration for injecting the gas filled in the interior of the shell (11). First, a nozzle body 20 is provided at the tip of the casing 11. In the nozzle body 20, a communication path 21, which is a passage for injecting gas to the outside by communicating the space inside the casing 11 with the outside, is formed. In addition, a valve port 23 is installed in the inner space of the casing 10 so as to be elastically supported by the spring 24 and to be in close contact with the inlet of the communication path 21. The spring 24 exerts an elastic force such that the valve port 23 is in close contact with the inside of the nozzle body 20. Here, the nozzle body 20 and the casing 11 can be moved relative to each other. That is, the nozzle body 20 is not fixed to the casing 11 but is in close contact with the valve opening 23 supported by the spring 24 while being inserted into the tip of the casing 11. When the spring 24 is supported inside the casing 11 and the nozzle body 20 is fixed, the casing 11 is movable while overcoming the elastic force of the spring 24. When the shell 11 is fixed, the nozzle body 20 is movable while overcoming the elastic force of the spring 24.

In this case, a plurality of communication grooves 22 are formed in the nozzle body 20 corresponding to the inlet of the communication path 21, so that the valve port 23 communicates with the nozzle body 20. Even if it is in close contact with the inlet, the gas inside the casing 11 can be injected to the outside through the communication path 21.

On the other hand, the packing 26 is provided to block the portion of the communication groove 22 so that the gas inside the casing 11 is not injected to the outside through the communication path 21 during the power generation. The packing 26 is fixedly installed in the casing 11 and moves integrally with the casing 11. Therefore, when relative movement of the casing 11 and the nozzle body 20 occurs, the packing 26 opens the communication groove 22 so that the inside and the outside of the casing 11 are connected to the communication path ( 21).

The tip of the nozzle body 21 and the casing 11 is configured to continuously maintain the communication state between the communication path 21 and the inside of the casing 11 at the time of triggering, that is, the gas injection state. Is provided. That is, a key holder 30 is formed around one outer surface of the nozzle body 21. The depth of the key holder 30 is about the same as the radius of the cross section of the spring key 32 to be described below.

A spring key 32 is installed on the inner surface of the tip of the casing 11 into which the nozzle body 21 is inserted. The spring key 32 tends to be tightened in the direction of the outer circumferential surface of the nozzle body 21. Thus, when the relative movement of the nozzle body 21 and the casing 11 occurs and the spring key 32 is brought to the position of the key holder 30, it is seated inside the key holder 30. At this time, the key holder 30 is formed to a depth corresponding to about half of the cross section of the spring key 32, when the spring key 32 is located in the key holder 30, the nozzle body 21 ) And the casing 11 are fastened to each other so that relative movement is impossible.

On the other hand, the position of the key holder 30 and the spring key 32 may be opposite to that described above. That is, the key holder 30 is located in the casing 11, the spring key 32 is located in the nozzle body 21, and the spring key 32 tends to extend in the direction of the casing 11. It is to have.

Hereinafter, the use of the gas bullet of this embodiment having the configuration as described above will be described in detail below.

Fig. 3 shows a state in which the gas bullet of the present embodiment is inserted into the magazine of the reverberant pistol. The gas bullet 10 according to the present invention can be used as a substitute for a pistol bullet to a pistol 1 that is generally used. That is, a plurality of gas bullets 10 are inserted into the magazine 2 of the pistol 1. At this time, the tip of the nozzle body 21 is positioned so as not to move seated in the engaging groove (2 ') formed in the inner tip of the magazine (2).

As shown in FIG. 4, the nozzle body 21 is seated in the locking groove 2 ′ of the magazine 2 as described above. As described above, in the state in which the gas shell 10 is completely seated in the magazine 2, there is a constant gap c between the tip of the shell 11 and the inner wall of the magazine 2. The interval c is a distance at which the casing 11 can move relative to the nozzle body 21 by triggering.

When the trigger 3 of the pistol 1 is pulled and triggered in the above state, the gas inside the casing 11 is injected. This state is shown in detail in FIG. 5. That is, when the trigger 4 of the pistol 1 is pulled and the trigger 4 is operated, the trigger 4 hits the explosive 13 stored at the rear end of the gas bullet 10 and explodes.

Accordingly, the casing 11 is inside the magazine 2 by the explosive force of the explosive powder 13 and the force of the bolt 4 striking the rear end of the gas shell 10. As far as advance. As such, the casing 11 is advanced because the nozzle body 20 is not seated in the engaging groove 2 'of the magazine 2 and cannot move.

As described above, when the casing 11 moves while overcoming the elastic force of the spring 24, the packing 26 moves together with the casing 11 and is separated from the valve port 23 so as to communicate with the communication groove 22. ) Is opened. Therefore, the gas inside the casing 11 is injected through the communication path 21.

At this time, when the casing 11 is advanced in the magazine 2, the spring key 32 is also moved together, and the spring to the key holder 30 at the time when the forwarding of the casing 11 is completed. The key 32 is seated. Accordingly, the shell 11 is engaged with the nozzle body 21 while overcoming the elastic force of the spring 24, so that the communication path 21 is kept open. Therefore, the gas stored in the casing 11 is injected 100%.

Here, the nozzle body 21 is seated in the engaging groove 2 'in the magazine 2, and is fixed without being moved by an impact caused by the operation of the bolt 4.

The gas bullet for the gas injector according to the present invention as described in detail above can be used by being mounted on an existing pistol, which does not require a separate gas injector, and in particular, the casing moves forward relative to the nozzle body by triggering. At the same time, the key holder and the spring key are fastened to each other to continuously maintain the forward state of the casing, that is, the nozzle open state. You can expect% spraying effect.
