[0031] Specifically:
[0032] This utility model is attached Figure 1 , Attachment Figure 2 , its technical solution: a new type of firearm silencer comprises an exhaust end cover 3, a silencer 4, an integrated silencer bowl a5, and an integrated silencer bowl b6. The exhaust end cover 3, the integrated silencer bowl a5, and the integrated silencer bowl b6 are sequentially installed into the silencer 4 to form a new type of firearm silencer 1 disclosed in the utility model. The integrated silencer bowl b6 has a threaded connection port at one end, which can be connected to the gun barrel 2.
[0033] The exhaust end cover 3 is provided with a threaded interface, a plurality of exhaust holes in a circumferential array, a middle exhaust hole, a blind hole for tightening with a wrench, and anti-slip grooves. The exhaust holes and blind holes can be circular holes or holes of other forms. The exhaust end cover 3 is connected to the silencer 4. When high-speed, high-temperature, and high-pressure gunpowder gas flows through the exhaust end cover 3, the gas can be slowly discharged from the middle exhaust hole and the plurality of exhaust holes to achieve the effect of silencing and reducing smoke and flames; the exhaust end cover 3 has anti-slip grooves and a blind hole for tightening a wrench.
[0034] The silencer 4 has a threaded interface at one end and a waist-shaped interface at the other end. The silencer 4 is the outer shell of the novel firearm silencer 1 and is a thin-walled part, and the integrated silencer bowl a5 and the integrated silencer bowl b6 can be installed inside. When the gunpowder gas exits the barrel 2, the silencer 4 plays a role in limiting the expansion of the expanding gas.
[0035] The integrated silencer bowl a5 is assembled from multiple silencer bowls, and is provided with multiple vents in the gas barrier disk, a lifting ring, multiple vent holes, and an intermediate vent hole. The silencer bowl is composed of a straight-faced disc and a Laval nozzle-like structure. The integrated silencer bowl a5 is composed of multiple straight-faced discs and a silencer bowl with a Laval nozzle-like structure. Those skilled in the art should understand that there are various ways to connect the silencer bowls, which can be in the form of a screw series, or welding, etc. The utility model is only a part of the embodiment, and is not a constraint on the utility model. Those skilled in the art should understand that when the gunpowder gas flows through the integrated silencer bowl a5, the silencer bowl, which is similar to the Laval nozzle structure, not only divides the gunpowder gas into inner and outer air chamber flows, but also generates a superposition of shock waves at the tightening portion between the silencer tube 4 to form a high-pressure, high-speed outer air chamber airflow; the gas barrier disk can effectively prevent the high-speed airflow from decelerating, and the vents, air holes, and intermediate air holes can form a constant pressure flow field for the gas flowing between the inner and outer air chambers and between the silencer bowls; the lifting ring facilitates the removal of the integrated silencer bowl a5 to improve maintenance efficiency.
[0036] The integrated silencer bowl b6 is provided with a threaded connection port at one end and a connection port at the other end, a plurality of vents, a plurality of gas barrier disks, and a waist-shaped interface connected to the silencer 4. The gas barrier disk structure is a straight-faced circular disk and a Laval nozzle structure. The integrated silencer bowl b6 is the first expansion air chamber, which is connected to the silencer 4 and the barrel 2. When the gunpowder gas flows through, it fills the inner air chamber and then discharges from the vent to the outer air chamber. During the flow of the outer air chamber, the gas barrier disk can effectively prevent the high-speed airflow from decelerating, and finally discharges to the outside of the integrated silencer bowl a5 air chamber.
[0037] The exhaust end cover 3 is connected to the silencer 4 through a threaded interface. The integrated silencer bowl b6 is connected and positioned with the silencer 4 through a waist-shaped interface. The threaded connection port is a threaded interface connected to the gun barrel 2. Those skilled in the art should understand that the integrated silencer bowl a5 and the integrated silencer bowl b6 can be installed in the silencer 4 in a detachable manner or in a non-detachable manner.
[0038] The exhaust end cover 3 is connected to the silencer 4 via a threaded interface, and the threaded connection port is connected to the gun barrel 2 as a self-locking threaded connection, so that the connecting thread will not loosen due to gas spinning during the shooting process of the firearm.
[0039] The working principle of the utility model is as follows: metal materials are selected, processed and assembled into the utility model, and then firmly installed on the firearm. When the trigger is pulled and the gunpowder is ignited, a high-speed, high-temperature, and high-pressure airflow is generated instantly, pushing the projectile forward; when the projectile moves to the muzzle of the gun barrel, the projectile will pass through the middle exhaust hole without obstruction, and the airflow will fill the inner chamber in the integrated silencer bowl b6, and then expand to the outer chamber. During the flow in the outer chamber, the gas barrier disk will effectively reduce the airflow speed, and finally be discharged to the outside of the integrated silencer bowl a5 air chamber; after the gas reaches the integrated silencer bowl a5, the silencer bowl similar to the Laval nozzle structure not only divides the gunpowder gas into inner and outer air chamber flows, but also generates shock wave superposition at the tightening part between the silencer tube 4, forming a high-pressure, high-speed outer air chamber airflow; the gas barrier disk of the airflow flowing in the inner and outer chambers can effectively prevent the high-speed airflow from decelerating, and the vents, vents, and middle vents can form a constant pressure flow field for the gas flowing between the inner and outer air chambers and between the silencer bowls; finally, the gas is slowly discharged from the middle exhaust hole and multiple exhaust holes of the exhaust end cover 3. At this point, the pressure, velocity, density, etc. of the gunpowder gas flow have been greatly reduced, achieving the purpose of reducing noise and reducing muzzle smoke and flame.
[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
