Incidentally, in the cartridge 300 described above, the rim case 301 and the bullet case 302 are made of brass. For this reason, when the blowback type model gun is based on the 45 caliber, the rim case made of brass has a weight of 18 g compared to the rim case (about 7 g) of the actual gun. If this heavy rim case is ejected from the blowback model gun, it will not fly like an actual gun, but will fall down from the drainage port, resulting in lack of realism.
In addition, the dischargeability of the rim case is poor due to the lack of gunpowder and the cartridge may damage the slide when it hits the discharge port.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a cartridge for a ignitable model gun that can provide a high sense of realism.

  In order to achieve such an object, the invention according to claim 1 is directed to a frame, a barrel connected to the frame by a barrel link, and a trigger, whereby the lock by the shear is released and the explosive in the cartridge is released. A hammer for igniting and igniting the gas, and the gas pressure at the time of ignition of the gunpowder raises the hammer at the time of rear seat along the barrel, forming an opening through which the cartridge that has been ignited can be ejected when returning A cartridge for use in a model gun comprising: a slide that closes when a next cartridge is loaded; and a retraction / retraction mechanism that retreats the slide on the frame. A cartridge case, an annular warhead provided at the tip of the case, a primer provided at the rear end of the case and larger than the opening of the warhead, A gunpowder provided in a cartridge case and disposed in the primer, and a firing portion provided in the cartridge so as to contact the gunpowder, wherein the cartridge case is made of aluminum, and the warhead is made of brass. And

  According to the present invention, it is possible to provide a cartridge for an ignition model gun that can provide a high sense of realism.

  The cartridge 300 includes a substantially cylindrical rim case 301, a cylindrical bullet case 302 that can be screwed to the tip of the rim case 301, a primer 303 provided at the bottom of the rim case 301, and a CAP explosive 304. And an O-ring 305 and a substantially conical inner 306.

<Operation>
The CAP gunpowder 304 is positioned in the rim case 301 in a state of being sealed with an O-ring 305 before rupture. At the time of rupture, the CAP explosive 304 is blown off into the bullet case 302 and a blast is discharged from a gap in the outer peripheral portion, and a rupture sound is generated around the periphery. It has come to resonate. At this time, since the detonator 114 is fixed, the cartridge 300 is moved to the left in the figure by the blast, and the slide 103 (see FIG. 3) is moved backward together with the firing pin 107.
After the CAP explosive 304 bursts, it can be reused by removing the bullet case 302 from the rim case 301, taking out the CAP explosive 304 and the inner 306, and then attaching the CAP explosive 304 or the inner 305 again.

Here, the rim case 301 is made of aluminum, and the bullet case 302 is made of brass.
For this reason, the cartridge 300 of the present application is almost the same 7 g as the rim case for an actual gun, and the way of flying at the time of excision is the same as that of the rim case for an actual gun, and a high sense of realism is obtained.
Further, since the cartridge 300 of the present application is lighter than the conventional cartridge, the burden on the blowback type model gun 200 is less.
Since the cartridge 300 of the present application uses brass and aluminum, the biting of the screw can be prevented.
In the cartridge 300 of the present application, since the bullet case 302 is heavier than the rim case 301, the cartridge 300 flies while rotating at the time of evacuation.

The above-described embodiment shows an example of a preferred embodiment of the present invention, and the present invention is not limited thereto, and various modifications can be made without departing from the scope of the invention. is there.
For example, in the above-described embodiment, the case of aluminum and brass has been described. However, other materials may be used as long as the same weight can be obtained.
