The utility model discloses to promote gunpowder gas shutting behind the shot motion inside the firearms, the muzzle does not have the gunpowder gas basically and dashes out to not only can guarantee the pressure and the energy of gunpowder gas, guarantee ammunition initial velocity, range and lethality, the aerodynamic noise and the flame of weapon oral area when can also reducing the shooting moreover.

Preferably, the bottom of the projectile is housed in the cartridge and the bottom of the projectile has a recess corresponding to the receptacle to ensure proper movement of the warhead in the cartridge and in the launcher during launch.

Preferably, the cartridge case is located the pellet rear portion and cladding pellet and bullet support, and the cartridge case needs to be tight mouthful when assembling to guarantee to be connected closely between pellet and the cartridge case, guarantee the gas tightness.

Preferably, the cartridge receiver is positioned in the cartridge case, and the periphery of the cartridge receiver is tightly attached to the inner wall of the cartridge case so as to ensure that the gas of the gunpowder is sealed; the top bulge of the projectile support is embedded into the groove at the bottom of the projectile so as to ensure the correct movement of the projectile; the diameter of the bullet support is the same as the diameter of the negative line of the firearm, and when the bullet support is launched, the bullet support moves forwards and is embedded into the rifling to drive the bullet to rotate forwards.

Preferably, the propellant powder is positioned in the cartridge and at the rear part of the bullet holder and is in close contact with the primer so as to ensure that the primer can smoothly ignite the propellant powder during the firing.

Preferably, the primer is located in the center of the bottom of the cartridge and protrudes slightly from the inner surface of the bottom of the cartridge.

Preferably, the adapter and barrel mouth are connected by threads.

This kind of structure makes things convenient for the assembly of adapter and barrel, ensures both connection firmly simultaneously.

The working method of the micro-sound sniping gun structure comprises the following steps:

1) when in launching, the firing pin fires the primer, the primer ignites the propellant powder, and the propellant powder is rapidly combusted to generate gunpowder gas;

2) the bullet holder moves forwards under the push of gunpowder gas and drives the bullets to move forwards together;

3) when the bullet holder moves to the opening part of the cartridge case, the part of the tight opening between the cartridge case and the bullet is opened and continues to move forwards;

4) then the projectile support is embedded into the rifling to drive the projectile to rotate forwards;

5) when the bullet holder and the bullet move to the adapter arranged at the mouth of the gun, the bullet holder is blocked by the adapter and stops moving, the gunpowder gas is locked in the gun, and the bullet continues to rotate forwards and is ejected out of the gun mouth.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, but the present invention is not limited thereto.

As shown in fig. 1-3, a micro-sound sniping gun structure comprises a barrel, a sniping bomb 2 arranged on the barrel and an adapter 1,

the sniper bullet 2 is arranged at the bottom of a barrel and comprises a propellant charge 4 and a projectile 3, the propellant charge 4 comprises a cartridge 5, a primer 8, a propellant powder 7 and a projectile holder 6, the primer 8 is positioned at the bottom of the cartridge 5, the projectile 3 is arranged in the cartridge 5 through the projectile holder 6, and the propellant powder 7 is positioned between the projectile holder 6 and the primer 8;

adapter 1 installs at the barrel oral area, and adapter 1's bore is less than the bore of barrel and is greater than the diameter of pellet 3, and the diameter of sabot 6 is less than the bore of barrel and is greater than adapter 1's bore, makes pellet 3 shoot the thorax mouth smoothly and can seal sabot 6 inside the bore.
