Description

Silencer structure

The present invention relates to a muffler structure, in particular to a combination design of a hollow tube body, a ballistic traveling tube body, a plurality of elastic chambers and a plurality of mufflers, so that the volume of the bullet can be greatly reduced, and only A little sound wave outflow, suitable for all kinds of pistols, submachine guns, sniper rifles or similar firearms.

According to the current use of firearms, the bullets are fired through the energy generated by the explosion of gunpowder in the barrel. However, after the gunpowder burns and explodes, the high-explosive volume and the release of a large amount of gas are instantaneously generated, thereby easily exposing the shooting position.

In particular, many current special combat units or special service units emphasize the need for good concealment and concealment, so they all hope to use silencers on the equipment of the firearms to improve the high-explosive volume generated after the shooting, avoiding high Exploding the volume to expose where you are hiding, thereby increasing the risk of threatening your own life.

However, the conventional silencer is not the same in design, but the common point is to reduce the high-explosion volume generated by the firearm. However, the high-explosion volume reduced by the existing silencer is mostly at 160db. Between ~132db, but at night or when there is no sound, the high-explosion volume between the 160db~132db that passes through the silencer still has a very high sound, and it is easy to expose the position where it is shot.

Therefore, in view of the above-mentioned deficiencies, the present creator can propose a structure of a muffler which can reduce the sound of 160 db to 132 db which is lower than that produced by a conventional muffler, so that the user can easily operate the assembly, and it is painstakingly researching. The design system is designed to provide user convenience and is the motive for the creators to develop.

The main purpose of this creation is to provide a muffler structure that is designed through a combination of a hollow tube body, a ballistic travel tube body, a plurality of bomb chambers, and a plurality of mufflers, through the edge of the ballistic exit of the bomb chamber. Close to the inner wall of the ballistic traveling pipe body, and the outer ring of the horn body of the muffler collar is gradually abutted against the inner wall of the hollow pipe body to form a plurality of silenced spaces for the bullets When passing through the plurality of elastic chambers, the inclined surface of the funnel body of the elastic chamber can bounce the sound wave into the silencing space, so that the sound wave can perform numerous reflection and impact actions in the silencing space of each segment, so that the sound wave can remain in the segment. In the silencing space, after a plurality of silenced spaces, only a few sound waves can flow out, and the volume generated after the bullet is fired can be greatly reduced, thereby increasing the overall silencing function.

The second purpose of the present invention is to provide a muffler structure. The ballistic inlet of the funnel body formed by the front elastic chamber and the middle elastic chamber has a funnel body inclined angle of 15 degrees to 20 degrees, so that the bullet is made. When entering from the ballistic entry, the slope of the funnel body can have the effect of sound cutting, thereby improving the overall noise cancellation effect.

The muffler structure of the present invention comprises a hollow pipe body, a ballistic traveling pipe body, a plurality of elastic chambers, and a plurality of muffler collars; the ballistic traveling pipe system is disposed in the hollow pipe body, and the ballistics travels on the pipe body The system is provided with a plurality of sections, and each section is provided with a plurality of openings in a spaced-apart manner; the other chamber is divided into a front chamber and a middle chamber, and the front chamber and the middle chamber are The sequence is arranged in the inner diameter of the plurality of sections of the ballistic traveling pipe body, and one end of the front stage elastic chamber and the middle stage elastic chamber is a ballistic inlet which gradually decreases backward from the middle into a funnel body, and the other end has a ballistic exit. And the muffler collar is arranged tightly on the outer diameter of the plurality of segments of the ballistic traveling pipe body, and the muffler collar is a gradually enlarged horn body, and the outer ring of the horn body is abutted On the inner wall of the hollow tube body to form a silencing space.
