Description

Technology Field

[0001] The present invention relates to a silencer for a firearm, and more specifically, to a silencer for a firearm that delays the noise and flame generated during the firing of a firearm to reduce pressure and thermal explosion. Background Technology

[0002] Generally, firearm suppressors are mounted on the tip of a gun to reduce the loudness of the gunshot and the flame generated during firing. Depending on the mounting method, they are classified into fixed and detachable types, and based on their structure, they are categorized into baffle and wipe types. The noise produced during firing is caused by the instantaneous expansion of high-pressure gas due to the explosion of gunpowder. Furthermore, suppressors reduce noise by ensuring that the high-pressure gas slowly disperses through multiple paths as it exits the chamber after the gunpowder explodes. These suppressors utilize materials that withstand high-temperature flames and shock waves while absorbing noise.

[0003] Conventional firearm suppressors are manufactured into individual parts through machining processes such as cutting, casting, or forging, and then assembled as a single unit. However, there have been limitations in manufacturing firearm suppressors while implementing complex internal baffle structures. Furthermore, firearm suppressors face challenges in enhancing product quality due to the need to design complex baffle structures that must withstand high-temperature flames and shock waves while absorbing noise, coupled with low productivity and precision.

Specific details for implementing the invention

[0017] Hereinafter, an embodiment of a gun silencer according to the present invention will be described in detail with reference to the attached drawings.

[0018] Figure 1 shows the exterior of a gun silencer, Figure 2 shows a cross-section of a part of the gun silencer, and Figure 3 shows the interior side with the cover separated.

[0019] The cover portion (20) is cylindrical in shape. That is, the cover portion (20) corresponds to the outermost part of the muffler (1) and is formed with a certain thickness. The cover portion (20) is double-layered with an inner wall (21) and an outer wall (22). The double-layered cover portion (20) consisting of an inner wall (21) and an outer wall (22) serves to effectively block noise generated inside the muffler (1).

[0020] A spiral partition (23, 24) is formed between the outer wall (22) and the inner wall (21) of the cover portion (20). Furthermore, a first spiral partition (23) is formed between the inner wall (21) and the outer wall (22) of the cover portion (20) to which the rear baffle portion (40) is formed, and a second spiral partition (24) is formed between the inner wall (21) and the outer wall (22) of the cover portion (20) to which the front baffle portion (50) is formed. Additionally, the first spiral partition (23) and the second spiral partition (24) are formed in different directions. That is, the first spiral partition (23) can be formed counterclockwise between the inner wall (21) and the outer wall (22) of the cover part (20), and the second spiral partition (24) can be formed clockwise between the inner wall (21) and the outer wall (22) of the cover part (20), and they may also be formed in opposite directions. The first spiral partition (23) and the second spiral partition (24) provide delay and noise functions by extending the flow of the explosion and flame discharged through the reverse diffusion part (30). A projection (25) is formed between the inner wall (21) and outer wall (22) of the cover portion (20) corresponding to the outer side of the front baffle portion (50) and the inner wall (21) and outer wall (22) of the cover portion (20) corresponding to the outer side of the rear baffle portion (40), so that the first spiral partition (23) separates the second spiral partition (24) and allows the rotation direction of the explosion and flame to be changed.

[0021] The connecting portion (10) is connected to the end of the gun on one side of the cover portion (20). Screw threads may be formed in the connecting portion (10) for attachment and detachment from the gun. The diameter of the connecting portion (10) may be larger than the muzzle of the gun. The cover portion (20) may be formed with an expanded diameter from the connecting portion (10).

[0022] The reverse diffusion section (30) is configured to radially diffuse the explosion and flame transmitted when the gun is fired and to discharge them between the inner wall (21) and the outer wall (22) of the cover section (20). In FIGS. 4 and 5, the reverse diffusion section (30) is composed of a diffusion tube (31) and a blocking plate (34). The diffusion tube (31) is configured at the entrance of the silencer (1), and a central hole (32) through which a bullet passes is formed in the center. The diffusion tube (31) has the shape of a dish, with the diameter widening as it extends forward from the central hole (32). The diffusion tube (31) is configured at regular intervals on the inner side of the cover section (20). Multiple diffusion holes (33) are formed penetrating the surface of the diffusion tube (31) at regular intervals from the central hole (32). The diffusion holes (33) cause the explosion and flame transmitted from the gun through the central hole (32) to be dispersed radially.

[0023] The blocking plate (34) of the reverse diffusion section (30) is formed at a certain distance in front of the diffusion tube (31), and the blocking plate (34) is designed to block the loud noise and flame ejected from the diffusion hole (33) and allow them to be discharged in reverse. The edge of the blocking plate (34) is integrally connected to the inner wall (21) of the cover section (20).

[0024] In FIG. 6, the rear baffle section (40) is intended to delay the explosion and flames passing through the reverse diffusion section (30). The rear baffle section (40) is formed with a plurality of first baffles (41) spaced apart, and each of the first baffles (41) is fixedly connected to the inner wall (21) of the cover section (20). A through hole through which a bullet passes is formed in the center of the first baffle (41). Each first baffle (41) is formed in a roughly cone shape. A plurality of first spiral protrusions (42) are formed in a certain direction on the outer surface of the first baffle (41).

[0025] The front baffle section (50) is intended to delay the explosion and flames passing through the rear baffle section (40). The front baffle section (50) has a plurality of second baffles (51) formed at regular intervals, and each of the second baffles (51) is fixedly connected to the inner wall (21) of the cover section (20). A through hole through which a bullet passes is formed in the center of the second baffle (51). Each second baffle (51) is formed in a roughly cone shape. A plurality of second spiral protrusions (52) are formed in a certain direction on the outer surface of the second baffle (51).

[0026] Additionally, the spacing between the first baffles (41) of the rear baffle section (40) is formed wider than the spacing between the second baffles (51) of the front baffle section (50). This allows the sensitivity effect to be increased by delaying noise by varying the spacing between the first baffle (41) and the second baffle (51).

[0027] Meanwhile, the gun silencer (1) according to the present invention can be manufactured as a single unit. That is, the gun silencer can be manufactured as a single unit by bonding and layering metal powder using a 3D printer. Therefore, the gun silencer (1) can be provided in a single form and structure without being separated or combined separately.

[0028] Additionally, FIG. 7 illustrates various forms of gun silencers depending on the diameter of the barrel of a gun. By considering the size of the baffle according to the bore length of the silencer (1), various spacings and baffle models capable of dispersing the explosion and flame can be selected. For example, FIG. 7a shows a diameter of 5.56 mm, FIG. 7b shows a diameter of 7.62 mm, FIG. 7c shows a diameter of 12.7 mm, and various other diameters can be selected.

[0029] The operation of the gun silencer of the present invention, constructed as described above, is explained.

[0030] First, to provide a noise suppression function for the firearm, the coupling part (10) of the suppressor (1) is attached to the end of the barrel of the firearm. When the trigger of the firearm with the suppressor (1) attached is pulled to fire a bullet, the bullet will be fired through the outlet (26) of the suppressor (1) after the explosion and flame are removed through the suppressor (1). Thus, when a bullet is fired from the firearm, the explosion and flame generated along with the firing of the bullet are transmitted toward the rear baffle part (40) through the central hole (32) formed in the diffusion tube (31) of the reverse diffusion part (30), and also diffuse through the diffusion hole (33) of the diffusion tube (31). The explosion and flame diffused through the diffusion hole (33) are blocked by the blocking plate (34) and retreat, and are discharged behind the diffusion tube (31). Additionally, the explosion and flame discharged behind the diffusion tube (31) are discharged between the inner wall (21) and the outer wall (22) of the cover part (20). Thus, the loud noise and flames generated by the firing of the bullet in the reverse diffusion section (30) are delayed.

[0031] Additionally, the explosion and flames discharged between the inner wall (21) and the outer wall (22) of the cover portion (20) are discharged while rotating counterclockwise along the plurality of first spiral partitions (23), causing a delay. Then, the explosion and flames passing through the first spiral partition (23) are discharged while rotating clockwise along the plurality of second spiral partitions (24) starting from the protrusion (25). Therefore, the explosion and flames are significantly delayed as they pass through the first spiral partition (23) and the second spiral partition (24) between the inner wall (21) and the outer wall (22) of the cover portion (20). Furthermore, as they pass through the protrusion (25) between the first spiral partition (23) and the second spiral partition (24), the direction of rotation is reversed, causing a further delay and blocking effect.

[0032] Next, the loud noise and flames discharged through the reverse diffusion section (30) are delayed and blocked as they pass through a plurality of first baffles (41) of the rear baffle section (40). Furthermore, they are discharged while rotating along the first spiral projection (42) formed on the outer surface of the first baffle (41). Additionally, since the outer edge of the first baffle (41) is sealedly coupled to the inner wall (21) of the cover section (20), the loud noise and flames temporarily remain while rotating on the outer surface of the first baffle (41) before being discharged, thereby creating a delay effect.

[0033] Additionally, the loud noise and flames discharged through the rear baffle section (40) are further delayed and blocked as they pass through the multiple second baffles (51) of the front baffle section (50). Furthermore, they are discharged while rotating along the second spiral projection (52) formed on the outer surface of the second baffle (51). Also, since the outer edge of the second baffle (51) is sealedly coupled to the inner wall (21) of the cover section (20), the loud noise and flames temporarily remain while rotating on the outer surface of the second baffle (51) before being discharged, thereby creating a delay effect.

[0034] Additionally, the spacing of the first baffle (41) of the rear baffle section (40) is wider than the spacing of the second baffle (51) of the front baffle section (50), so that the loud noise and flames are relatively more captured, delayed, and blocked by the first baffle (41), and the second baffle (51) of the front baffle section (50) further delays and blocks the loud noise and flames that have been delayed and blocked by passing through the first baffle (41) of the rear baffle section (40), so that the loud noise and flames are almost not discharged through the outlet (26).

[0035] As described above, the gun silencer according to the present invention has the advantage of improving the function of an integrated gun silencer by first delaying and blocking through the reverse diffusion section, second delaying and blocking through the spiral partition of the cover section, third delaying and blocking while passing through the rear baffle section, and fourth delaying and blocking while passing through the front baffle section.
