Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 2, a detachable gun muzzle device comprises a muzzle cap 1 and a muzzle tube 2, wherein one end of the muzzle cap 1 is provided with a clamping end 11, the clamping end 11 is detachably connected with a 92-series pistol, the other end of the muzzle cap 1 is provided with an extension section, the extension section is detachably connected with the muzzle tube 2, and the muzzle tube 2 is provided with a gas release hole 21; the muzzle cap is 131.5mm, the clamping end is 1113.5mm, and the extension section is 12mm; the air release holes 21 are provided with a plurality of rows, at least 5 air release holes 21 are provided, the width of each air release hole 21 is 2mm, the air release holes 21 are in an inclined strip shape in a front view, the air release holes 21 are in a semi-annular shape in a top view, and the air release holes 21 are arranged around the half circumference of the muzzle tube 2; the angle between the length direction of the air release hole 21 and the axis of the bore-hole pipe 2 is 105 degrees, when the bullet moves forwards at high speed, the residual gunpowder gas is guided out from the back side. An outlet 23 is arranged at the front end of the bore pipe 2, and the diameter of the outlet 23 is smaller than the inner diameter of the bore pipe.

Gunshot sound generation principle: when a trigger is pulled, a firing pin impacts the bottom of a bullet to trigger a primer, the primer ignites the propellant powder in the bullet, then the generated hot gas pushes the bullet to rush out of a gun mouth, and at the moment of rush out, shock waves can violently compress surrounding air, so that huge sound is generated, the intensity of the sound depends on the diffusion speed of the gas, the higher the chamber pressure is, the more violent the shock waves are, and the louder the gun sound is; in addition, the gas in the gun bore contains components which are not fully combusted when discharged, and once the gas is sprayed out of the gun barrel and contacts with fresh air, the gas can be combusted again to cause secondary detonation, secondary muzzle flame is generated at the same time, and the secondary muzzle flame is superposed on the previous shock wave, so that the sound of the gun can be louder.

The utility model discloses reduce the principle of sound: the bullet is shot from left to right and is discharged from a muzzle, when the bullet is in a smooth muzzle tube, rapidly expanded gas can rush into the muzzle tube, residual gunpowder gas is led out to the upper right side through the air leakage hole 21 in the shooting process, the residual gunpowder gas is prevented from being diffused at the muzzle and causing secondary detonation with air, the recoil moment of the pistol is counteracted, and after the bullet is discharged from the outlet 23, the diameter of the outlet 23 is smaller than the inner diameter of the muzzle tube, the gas is retained in the muzzle tube or is discharged from the air leakage hole 21, the diffusion speed of the gas can be effectively reduced, the energy of the bullet is consumed in the muzzle tube, the impact on the air after the bullet is discharged is small, the noise reduction of the muzzle is effectively achieved, the hearing of a shooter is protected, and the psychological pressure of the shooter is relieved.

The end of the clamping end 11 is provided with a plurality of clamping blocks 110 arranged in a ring shape, the outer side of the extension section is provided with an external thread 12, and one end of the bore tube 2 is provided with an internal thread 22 matched with the external thread 12. The stable joint of 1 rear end of muzzle cap and pistol front end, 1 front end of muzzle cap and threaded connection such as joinable thorax mouth pipe 2 or hush pipe, muzzle cap 1 is connected the pistol front end, does not act on the barrel, does not destroy barrel vibrations law.

Bore pipe 2 self has certain weight, consequently can effectively reduce the muzzle and jump the amplitude, mitigatees recoil degree, simultaneously owing to carry out effective dispersion with the gas for muzzle flame reduces, has alleviateed the psychological influence to shooting the hand, can show the accuse rifle ability that improves the police officer, promotes the shooting precision, improves the shooting speed.

The above description is a preferred embodiment of the present invention, and a person skilled in the art can make several modifications and improvements without departing from the principles of the present invention, and these should also be regarded as the protection scope of the present invention.
