Abstract
Description
Technical Field
[0001] This invention relates to the field of silencer technology, and more particularly to a modular gun silencer. Background Technology
[0002] When a gun is fired, the noise mainly comes from the impact and vibration of the surrounding air caused by the high-pressure gas generated by the burning gunpowder rushing out of the muzzle the moment the bullet leaves the barrel. As a noise reduction device installed at the muzzle, the silencer needs to block the propagation of sound waves while allowing the bullet to pass through smoothly.
[0003] Currently, the general principle of existing silencers is to reduce noise peaks by decreasing the speed and flow rate of propellant gases exiting the muzzle. This is often achieved through internal structures such as perforated baffles or steel wires. However, these traditional silencers have several drawbacks: First, their structural design is limited by traditional manufacturing processes, often consisting of simple geometric shapes (such as round holes, cylinders, and cones) in a single or combined form, resulting in a simplistic silencing principle and limited performance improvement. Second, the noise control effect of the same type of silencer is relatively fixed, lacking adjustability and failing to meet the differentiated noise reduction requirements of different scenarios. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is how to improve the noise reduction performance of the muffler and how to adjust the noise control effect to meet the usage needs of different scenarios.
[0005] To solve the above-mentioned technical problems, the present invention provides a modular gun suppressor, including a main body unit and at least one reinforcing unit. The front end of the main body unit and the rear end of the reinforcing unit are adapted to be detachably connected, and the reinforcing units are adapted to be detachably connected end to end. The main body unit and the reinforcing unit are provided with guide plates that are spirally distributed along the axial direction, so that the main body unit and the reinforcing unit form a spiral guide channel extending along the axial direction. The guide plates are inclined from the inside to the outside in the radial direction and from the back to the front in the axial direction.
[0006] The muffler of this invention has a detachably connected main body unit and reinforcement unit. One or more reinforcement units can be used as needed to adjust the noise control effect and meet the noise reduction requirements in different scenarios. The spiral flow channel inside the muffler can guide the radial diffusion and axial spiral motion of the gas. The friction between the gas and the guide plate reduces the airflow speed and slows down the noise generated by the gas impacting the inner wall of the muffler. Compared with the traditional structure, it can make greater use of the internal volume of the muffler, thereby improving the noise reduction effect. The tilt direction of the guide plate is consistent with the direction of gas movement from the rear to the front of the muffler, ensuring that the gas entering the muffler can smoothly enter the spiral motion state, reducing the reverse impact between the airflow and the guide plate and the local turbulence noise. In turn, the continuous friction effect can efficiently reduce the flow velocity and improve the noise reduction effect.
[0007] Furthermore, the main unit comprises, from rear to front, a sleeve, a gas storage section, a flow guide section, and a docking section connected sequentially. The sleeve is a cylindrical structure, the outer wall of the gas storage section is a curved surface that gradually expands from back to front, the outer wall of the flow guide section is a cylindrical surface, and the outer wall of the docking section is a curved surface that gradually converges from back to front. A connector is provided at the front end of the docking section. The flow guide plate in the main unit is disposed inside the flow guide section and the docking section. The main unit has an ingenious structural design: the sleeve can stably connect to the muzzle; the expanding curved surface of the gas storage section provides more space to store initial gas to reduce the explosion volume; the cylindrical surface of the flow guide section facilitates the arrangement of a spiral structure; and the converging curved surface and connector of the docking section ensure a stable connection with the enhancement unit.
[0008] Furthermore, the gas storage section is internally equipped with a guide pipe and a diffuser ring arranged from back to front. The guide pipe is a cylindrical structure, coaxially connected to the sleeve portion, and its opening diameter is smaller than that of the sleeve portion. The inner wall of the diffuser ring is a curved surface that gradually expands from back to front. There are gaps between the sidewalls of the guide pipe and the diffuser ring and the outer shell of the gas storage section. The diffuser ring has multiple diffuser holes. The guide pipe can constrain the initial airflow direction, and its smaller opening diameter can initially compress the airflow. The expanding inner wall and diffuser holes of the diffuser ring promote radial diffusion of the gas. The gaps between the guide pipe, the sidewalls of the diffuser ring, and the outer shell provide buffer space for the gas. Together, they reduce the initial gas pressure and flow rate, and reduce explosion noise.
[0009] Furthermore, the rear of the guide section is provided with multiple spiral guide ribs, the rear ends of which are connected to the inner wall of the diffuser ring, and the front ends of which are connected to the guide plate. The guide rib design allows the gas to smoothly transition from the diffuser ring to the guide channel of the guide plate, avoiding airflow turbulence and additional noise; the spiral structure of the guide ribs also helps the gas maintain spiral motion, continuously decelerating through friction, ensuring the continuity of the noise reduction process, and further improving the control effect on airflow speed.
[0010] Furthermore, the reinforcement unit comprises reinforcement sections and connecting sections connected sequentially from rear to front. The outer wall of the reinforcement section is cylindrical, and its rear end has a docking groove. The inner wall of the docking groove is a curved surface that gradually converges from back to front. The front end of the docking groove has an insertion hole for the insertion tube to be inserted to form a plug-in fit. The outer wall of the connecting section is a curved surface that gradually converges from back to front, and the front end of the connecting section has an insertion tube. The guide plate in the reinforcement unit is disposed inside the reinforcement section and the connecting section. The reinforcement unit has an ingenious structural design, enabling it to be stably plugged into the main unit or other reinforcement units through the docking groove and insertion hole, ensuring connection reliability. The cylindrical surface of the reinforcement section and the converging curved surface of the connecting section extend the gas movement path, and the internal guide plate continuously guides the gas to spiral and decelerate. The overall noise reduction effect is improved by increasing the number of noise reduction units, and the modular design facilitates quick assembly and disassembly according to needs, balancing portability and noise reduction performance.
[0011] Furthermore, both the main body unit and the reinforcing unit have mesh ribs on their surfaces. This mesh rib structure enhances the structural strength of the muffler, allowing for thinner sidewalls to reduce weight and achieve lightweight design. It also increases surface friction, ensuring smooth assembly and disassembly in complex environments such as dampness and mud, thus solving the operational inconvenience caused by the smooth surface of traditional mufflers.
[0012] Furthermore, the mesh shape of the mesh reinforcement is rhomboid or hexagonal. These two shapes can evenly distribute structural stress, further improving the overall strength of the muffler. At the same time, they can form a more stable support structure with the same amount of material, enhancing the weight reduction effect. Moreover, the regular mesh shape can ensure the uniformity of surface friction and improve the convenience of disassembly and assembly.
[0013] Furthermore, the tilt angle of the guide plate relative to the axis is 30°-60°. The preferred tilt angle range can ensure that the gas moves smoothly in a spiral motion along the guide plate, avoiding the problem of excessive airflow impact due to too small an angle or excessive flow velocity due to too large an angle. At the same time, it can effectively reduce the airflow velocity through an appropriate friction area, balancing the smoothness of airflow movement and the deceleration effect, and improving the noise reduction effect of the guide channel.
[0014] Furthermore, both the main body unit and the reinforcing unit are integrally molded structures made using 3D printing technology. This allows for the precise realization of complex internal structures (such as spiral guide plates, mesh ribs, etc.) in the main body unit and the reinforcing unit, eliminating the need for traditional assembly processes and simplifying the production process. Integral molding also ensures the integrity and precision of the structure, avoiding gas leakage or insufficient structural strength caused by assembly gaps.
[0015] Furthermore, the main body unit and the reinforcing unit are made of titanium alloy. The high strength-to-weight ratio of titanium alloy further reduces the weight of the suppressor, while its excellent corrosion resistance ensures stable performance in harsh outdoor environments and frequent use. This resolves the contradiction between weight and durability inherent in traditional materials, meeting the stringent requirements of firearms for a lightweight and durable suppressor.
[0016] In summary, the present invention has the following advantages over the prior art: (1) Improved noise reduction performance: The present invention guides the gas radial diffusion and axial spiral motion through a spiral flow channel, and uses the friction of the flow guide plate to reduce the airflow speed. Combined with the gas storage section, guide pipe, diffusion ring and other structures, it can make greater use of the internal volume and significantly improve the noise reduction effect compared with traditional multi-layer noise reduction bowl and other structures. The tilt direction of the flow guide plate is consistent with the gas movement direction, which reduces the airflow impact and turbulence noise, and further enhances the noise reduction performance.
[0017] (2) Noise control can be flexibly adjusted: The present invention adopts a modular design. By adding different numbers of enhancement units, it can switch between easy operation and powerful noise reduction according to the needs of the scenario, which solves the problem of fixed and difficult-to-adjust noise control of existing silencers.
[0018] (3) Lightweight and improved operability: The complex structure is formed in one piece by using 3D printing technology. The titanium alloy material has both high strength and lightweight, which solves the problem of inconvenience in carrying and operating caused by the large size and weight of traditional mufflers. The external mesh ribs increase friction and ensure smooth disassembly and assembly in complex environments, further optimizing operability.
[0019] (4) Superior structural strength and durability: The mesh structure enhances the overall strength and can reduce the weight by thinning the sidewalls; the titanium alloy material has excellent corrosion resistance and can maintain stable performance in harsh outdoor environments and frequent use, thus solving the contradiction between the weight and durability of traditional materials.
[0020] (5) More efficient and flexible production and manufacturing: 3D printing integrated molding process simplifies the production process and increases the production speed. The interface can be flexibly adjusted to adapt to different gun calibers and structures. No complicated assembly is required, avoiding the structural gap problem of traditional processes, which is conducive to rapid production and application. Attached Figure Description

[0032] Combination Figures 1 to 6 As shown, a specific embodiment of the present invention provides a modular gun suppressor, including a main body unit 1 and an enhancement unit 2. The number of enhancement units 2 can be one or more. The main body unit 1 and the enhancement units 2, as well as each enhancement unit 2, are detachably connected. The silencing effect and the overall size can be flexibly adapted by adjusting the number of enhancement units 2.
[0033] In this embodiment, the main body unit 1 and the reinforcing unit 2 of the silencer are both integrally formed using 3D printing technology, which can accurately realize the complex internal and external structural design; at the same time, the size of the silencer can be adjusted according to different gun calibers, making it highly versatile.
[0034] In a preferred embodiment, the main body unit 1 and the reinforcing unit 2 are made of titanium alloy. Titanium alloy has an extremely high strength-to-weight ratio and excellent corrosion resistance, ensuring that the silencer can maintain optimal performance in harsh outdoor environments and frequent use, meeting the strict requirements of firearms for silencers to be lightweight and durable.
[0035] Combination Figure 1 and Figure 2 As shown ( Figure 2 The dashed line in the middle is the axis of the silencer, and the arrow indicates the direction of bullet movement (the direction the arrow points is defined as the front side, and the opposite direction is the rear side). The main unit 1 includes, from the rear end to the front end, a socket section 101, an air storage section 102, a flow guide section 103, and a docking section 104.
[0036] The sleeve part 101 is a cylindrical structure used to fit with the muzzle to realize the assembly of the silencer.
[0037] The outer wall of the gas storage section 102 is a curved surface that gradually expands from back to front, forming a large-volume cavity inside to store the propellant gases at the initial stage of bullet firing, reducing the initial explosion volume. Inside the gas storage section 102, an axially arranged guide pipe 108 and diffuser ring 109 are provided. The guide pipe 108 is cylindrical and coaxially connected to the sleeve part 101. Its front opening diameter is smaller than the inner diameter of the sleeve part 101, which can constrain the initial direction of airflow. The diffuser ring 109 is located in front of the guide pipe 108, and its inner wall is a curved surface that gradually expands from back to front. Multiple circumferentially evenly distributed diffuser holes 110 are provided on its side wall. A gap is left between the outer walls of the guide pipe 108 and the diffuser ring 109 and the outer shell of the gas storage section 102 for gas buffer diffusion.
[0038] The outer wall of the guide section 103 is cylindrical, and the interior is equipped with a main guide plate 106. The guide plate is spirally distributed along the axial direction to form a spiral main guide channel 107. The rear of the guide section 103 is provided with 3-6 spiral guide ribs 111; the rear end of the guide ribs 111 is connected to the inner wall of the diffuser ring 109, and the front end is smoothly transitioned to the main guide plate 106, guiding the gas smoothly from the diffuser ring 109 into the spiral guide channel.
[0039] The outer wall of the docking section 104 is a curved surface that gradually converges from back to front, and the front end is provided with a main body insertion pipe 105 for connecting with the enhancement unit 2. The main body guide plate 106 and the main body guide channel 107 extend into the interior of the docking section 104, so that the gas maintains a spiral motion state before entering the enhancement unit 2.
[0040] The outer wall of the main body unit 1 is provided with continuous main body mesh ribs 112, which can enhance the structural strength, thereby reducing the thickness of the outer shell and achieving a lightweight design. At the same time, the main body mesh ribs 112 can increase the surface friction of the main body unit 1, facilitating disassembly and assembly operations in complex environments. In this embodiment, the mesh shape of the main body mesh ribs 112 is rhomboid; in other embodiments, the mesh shape of the main body mesh ribs 112 is hexagonal. Both shapes can evenly distribute structural stress and improve the overall strength of the main body unit 1.
[0041] Combination Figure 3 and Figure 4 As shown ( Figure 4 The dashed line in the middle is the axis of the silencer, and the arrow indicates the direction of bullet movement (the direction the arrow points is defined as the front side, and the opposite direction is the rear side). The reinforcement unit 2 includes the reinforcement section 201 and the connecting section 202 from the rear end to the front end.
[0042] The outer wall of the reinforcing section 201 is cylindrical, and a mating groove 206 is provided at the rear end. The inner wall of the mating groove 206 is a curved surface that gradually converges from back to front, matching the shape of the front outer wall of the mating section 104 of the main unit 1. The bottom of the mating groove 206 is provided with an insertion hole 207, the inner diameter of which is adapted to the outer diameter of the main insertion tube 105 to form an insertion fit. Preferably, the insertion hole 207 and the main insertion tube 105 are interference-fitted to ensure connection stability and sealing.
[0043] The outer wall of the connecting section 202 is a curved surface that gradually converges from back to front. The front end is provided with a reinforcing insertion tube 203, whose structure is the same as that of the main insertion tube 105, and is used to connect with the docking groove 206 of the next reinforcing unit 2.
[0044] The enhanced section 201 and the connecting section 202 are equipped with enhanced guide plates 204 to form a spiral enhanced guide channel 205. The spiral direction is consistent with the main guide channel 107 to ensure the continuity of gas movement.
[0045] The spiral flow channel inside the muffler guides the gas radial diffusion and axial spiral motion, and reduces the airflow speed through the friction between the gas and the guide plate, thus mitigating the noise generated by the gas impacting the inner wall of the muffler.
[0046] The outer wall of the reinforcing unit 2 is provided with continuous reinforcing mesh ribs 208, which can enhance the structural strength and surface friction. The structure of the reinforcing mesh ribs 208 is consistent with that of the main mesh ribs 112, which facilitates manufacturing, maintenance and replacement, and improves the compatibility and practicality of the modular muffler.
[0047] In this embodiment, both the main guide plate 106 and the reinforcing guide plate 204 are inclined radially from the inside to the outside and axially from the back to the front. This ensures that the inclination direction of the guide plates is consistent with the direction of gas movement from the rear to the front of the muffler, guaranteeing that the gas entering the muffler can smoothly enter a spiral motion state, reducing the reverse impact between the airflow and the guide plates and local turbulent noise. The inclination angle of the main guide plate 106 and the reinforcing guide plate 204 relative to the axis is 45°, ensuring smooth spiral motion of the gas along the guide plates while reducing the flow velocity through friction between the gas and the guide plates, thus mitigating impact noise on the inner wall. In other embodiments, the preferred inclination angle of the main guide plate 106 and the reinforcing guide plate 204 relative to the axis is in the range of 30°-60°, simultaneously ensuring both guiding and noise reduction effects.
[0048] The modular assembly methods of the above-mentioned silencers include: Basic mode, using only the main unit 1, suitable for scenarios with high portability requirements. In this mode, the gas is buffered by the gas storage section 102, decelerated by the guide section 103 and the docking section 104 of the main unit 1 before being discharged, achieving basic noise reduction. Enhanced mode, combined with... Figure 5 and Figure 6As shown, 1-3 reinforcing units 2 are connected to the front end of the main unit 1. Figure 5 This is the assembly state of one reinforcement unit. Figure 6 (Assembled with two enhancement units) By increasing the movement path and friction frequency of gas within the spiral guide channel, the noise reduction effect is improved.
[0049] The silencer provided in the above embodiments achieves flexible adjustment of the silencing effect through modular design. It can quickly switch between basic silencing and high-efficiency silencing by increasing or decreasing the number of units according to the needs of the scenario, solving the limitation of the fixed effect of traditional silencers. The internal spiral flow channel, together with the guide tube, diffusion ring and other structures, guides the gas to diffuse spirally and reduces the speed efficiently through friction, significantly improving the silencing performance. The combination of 3D printing one-piece molding process and titanium alloy material ensures structural strength while achieving a lightweight design, taking into account durability and ease of operation. The mesh rib structure on the surface further optimizes the structural stability and ease of assembly and disassembly. Overall, it meets the comprehensive needs of firearms for silencing effect, weight and operation performance in different scenarios, and has significant practical value.
[0050] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
