REFILE CARTRIDGE, SIMULATED GUN DEVICE SHOOTING TRAINING SIMULATION SYSTEM USING THE SAME}

The present invention relates to a shooting training simulation system, and to a refillable cartridge case, a simulated firearm, and a shooting training simulation system using the same, which can be continuously and repeatedly used by reloading only gunpowder without a warhead.

Conventionally, a simulated firearm used in a shooting game or shooting training system using a model gun rather than an actual gun executes a blowback effect at the same time as the user's trigger is triggered by compressed air, special gas, motor driving method, etc. It is generally implemented in such a way that the virtual percussion sound generated by the explosion of the gunpowder of the ammunition by a speaker or the like and the shooting effect sound generated when the bullet collides with an object are output.

However, there is a problem in that the user's enjoyment cannot be improved because the realistic effect of actual shooting cannot be provided by providing only the effect on the sight and hearing of the user of the conventional simulated firearm. Therefore, it can be said that the performance of these simulated firearms is determined by properly realizing the feeling of real shooting.

In particular, simulated firearms filled with gas that do not use gunpowder are difficult to properly realize the feeling of being fired, and the realism of the gunpowder explosion is reduced due to the recorded sound source. Since the effects such as ejection of cartridges and cartridge shells cannot be realized at all, in most cases, they are used only in shooting games, and are rarely used in the shooting training of police and soldiers who actually handle firearms.

In addition, in the case of a simulated firearm using conventional gunpowder, unlike the above-described gas-type simulated firearm, an effect similar to shooting using an actual bullet can be obtained as the explosion of the gunpowder occurs, but a large number of As bullets are required, there is a problem in that expensive new bullets must be continuously supplied and the operating cost is considerable.

1 and 2 , the simulated firearm 100 to which the refill cartridge case used in the shooting training simulation system according to the embodiment of the present invention is applied is triggered by the pulling of the trigger 111 and the trigger 111 . A ball 116 that applies an impact to the loaded refill casing 200 is mounted, and a gas pipe 113 formed inside and into which the explosive gas emitted from the refill casing 200 is injected according to the percussion Body 110) , A plurality of refill cartridge casings 200 are filled side by side in one direction in the inner space, and one refill casing 200 is exposed to the upper portion, and the magazine 120 and body 110 are coupled in one direction with the body 110 . ) coupled to enable forward and backward movement on the upper part, and may include a slide 130 for loading one refill cartridge 200 in the magazine 120 inside the body 110 when retracting, and the slide 130 is , it is possible to generate a blowback (blow back) by retreating to the pressure generated as the explosive gas is injected into the gas pipe 113 .

The body 110 may be formed in an appearance similar to that of a general firearm, particularly a pistol, and has a trigger 111 that the user manipulates the percussion through a finger and a handle 118 that the user holds by hand, and is made of a metal material. can

In particular, the refill cartridge 200 is seated in the internal space of the body 110, and a loading space at a position opposite to the ball 116 is provided, and when the trigger 111 is operated after loading, the tumbler 115 is As the back of the ball is hit, an impact is applied to the percussion detonator on the back of the refilled cartridge case 200 in which the ball is loaded. As the solid gunpowder explodes by the impact, an explosion sound and explosive gas are generated, thereby firing.

The magazine 120 may be inserted and coupled into the inner space of the handle 118 of the body 110, and a plurality of refill cartridges 200 may be mounted side by side in the longitudinal direction. The top of the magazine 120 may be exposed to the outside so that the refill cartridge 200 of one foot can be inserted into the interior of the body 110 when the body 110 is mounted and then loaded.

In detail, the gas pipe 113 formed inside the body 110 has a gas bar 117 corresponding to an external outlet for gas discharging of the refill cartridge 200 and reduces the internal area of the gas pipe 113 at the same time. A support jaw 119 for supporting the moving direction of the gas bar 117 may be further formed, and accordingly, when the explosive gas is released from the refill casing 200 by the percussion, the gas at a higher pressure by the above-described structure By pushing the bar 117 forward, the laser module can be turned on.

Referring back to FIG. 2 , in the simulated firearm 100 of the present invention, when a striker applies an impact to the rear surface of the refill case 200 by the user's pulling of the trigger 111, the gunpowder mounted in the internal space explodes. Accordingly, gas is ejected to the front of the refill casing 200, and the gas ejected forward is turned on as the aforementioned switch 143 is pressed, and the laser light source 141 is turned on to output the laser, and at the same time, the body 110 By pushing the slide 130 coupled to the upper part of the rearward, a blowback effect can be implemented.

According to this structure, the shooting training simulation system using a refilled cartridge shell according to an embodiment of the present invention can significantly reduce the cost by using a refilled shell shell that can replace the solid explosive inside by replacing the expensive blank shell during shooting training. In addition, it has the advantage of being able to implement not only shock, noise, smoke and flame effects similar to those that occur in real gun shooting by the explosion of solid explosives in the refill case, but also a blowback effect. It can also be used for shooting training in the industry that deals with actual firearms.

A laser module in which a laser light source, a battery and a switch are mounted, coupled to the muzzle of the body, the switch is connected to the gas pipe, and the switch is advanced by the pressure to drive the laser light source to irradiate the laser forward
A simulated firearm further comprising a. One or more simulated firearms that use a refill cartridge and irradiate a laser forward when fired;
a beam projector for displaying one or more targets on the screen;
an image processing device for detecting a hit point generated by the laser generated by the simulation gun on the target;
According to the execution of a preset shooting training simulation, the beam projector is controlled to provide a screen suitable for the training content, and the score obtained by the user is calculated based on the shot point transmitted by the image processing device and reflected in the training content including a control server;
The refill cartridge case,
one or more gunpowder caps filled with solid explosives are mounted;
A first Pigap having an external discharge port for discharging the explosive gas of the solid explosive to the outside is formed in the front of the bullet barrel is inserted and fixed in the internal space;
a second Pigap that is detachably coupled to the first Pigap and can be recombined upon separation; and
and a percussion detonator that is inserted and fixed in the inner space of the second armor, is disposed to face the rear surface of the bullet, and applies an impact to the gunpowder cap by an external force,
The bullet,
an internal discharge port which is inserted in a form in which the closing surfaces of one or two or more explosive caps replaceable inside are in contact, and discharges the explosive gas of the solid explosive in the direction of the external discharge port; and
A shooting training simulation system comprising: a first O-ring fitted to a stepped portion formed on the outer surface of the inner discharge port, the first O-ring being in contact with the inner surface of the first armor plate to fix the bullet barrel and the first armor plate to each other. 10. The method of claim 9,
The control server is installed in one or more regions or shooting practice ranges,
A head office server that communicates with the control server through an information communication network to perform overall monitoring of the execution of the shooting training simulation and collect operation information
A shooting training simulation system further comprising a.
