Description

Technical Field

[0001] The invention belongs to the technical field of weapons such as automatic firearms and artillery, and in particular relates to a dual-mode combined muzzle brake. Background Art

[0002] The muzzle brake is an important part of the modern artillery system. Its main function is to reduce the recoil force generated when the artillery is fired. The recoil force is the thrust in the opposite direction of the firing direction generated when the gunpowder gas is ejected outward after the explosion in the gun barrel. This thrust will affect the stability and shooting accuracy of the artillery.

[0003] Traditional muzzle brakes usually use a single exhaust method to guide gunpowder gas to one side or the front to generate reverse thrust, thereby reducing recoil, recoil and vibration. Although this design is effective to a certain extent, there are several problems in actual application: First, a single exhaust method often cannot provide sufficient recoil effect in complex combat environments such as high temperature, confined space or high-frequency firing, and the recoil reduction effect is not ideal, which in turn affects shooting accuracy; second, the traditional design lacks flexibility and cannot adjust the gas exhaust method according to different combat needs, resulting in reduced efficiency or increased safety hazards; in addition, continuous firing may cause the muzzle temperature to rise rapidly, affecting the performance and safety of the muzzle brake. Due to the lack of effective thermal insulation protection or modular replacement design, the equipment is prone to overheating, wear or damage, making maintenance difficult and affecting long-term combat capabilities. Summary of the invention

[0004] The purpose of the present invention is to provide a dual-mode combined muzzle brake, which can be used to solve technical problems existing in traditional muzzle brakes in complex combat environments, such as insufficient recoil effect, difficult to adjust gas exhaust mode, and frequent use leading to component overheating and safety risks.

[0005] The technical solution to achieve the purpose of the present invention is:

[0006] A dual-mode combined muzzle brake, comprising: a brake body, a shell and an end cap;

[0007] The front end of the recoil brake body is connected to the end cap;

[0008] The end cap is arranged on the outside of the recoil brake body;

[0009] The first exhaust hole and the second exhaust hole are symmetrically arranged on the left and right sides of the recoil brake body, wherein the first exhaust hole is located behind the second exhaust hole, and the size of the first exhaust hole is larger than that of the second exhaust hole;

[0010] The left and right sides of the shell are parallel to the axis and provided with multiple rows of oblique side hole groups, which are inclined toward the rear end of the muzzle brake body;

[0011] There are two working modes:

[0012] In the first working mode, the outer shell is not used, and the recoil brake body and the end cap form a complete recoil brake device; when the gun is fired, the gunpowder gas is discharged through the first exhaust hole and the second exhaust hole of the recoil brake body;

[0013] In the second working mode, the outer shell, the muzzle brake body and the end cap form a complete muzzle brake device; the inclined side hole group of the outer shell matches the first exhaust hole and the second exhaust hole of the muzzle brake body, guiding the gunpowder gas to accelerate outward to the rear side of the gun.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] (1) The boss of the recoil brake body and the groove of the shell form a nested connection pair, and the channel of the oblique side hole group is precisely connected with the first exhaust hole and the second exhaust hole of the recoil brake body in the axial direction of the center hole of the shell. This design ensures that when the gun is fired, the gunpowder gas can be effectively guided through the oblique side holes of the shell, accelerating the gas flow to the rear side of the gun, thereby more efficiently utilizing the gas reaction force, significantly reducing the recoil force, and improving the recoil effect.

[0016] (2) The present invention adopts a dual-mode working mechanism, which allows users to flexibly choose whether to use the shell according to different combat needs, thereby achieving the best recoil efficiency and gas emission control effect. In the first mode, when used without a shell, the gas flow rate can be minimized to the greatest extent, thereby achieving the best recoil efficiency, which is suitable for combat scenarios that require rapid release of gas to reduce recoil; in the second mode, when used in conjunction with the shell, the direction and speed of gas emission can be accurately controlled, effectively reducing recoil and optimizing airflow distribution, reducing the harm of shock waves, smoothly diffusing smoke, improving the field of vision after launch, helping operators to respond quickly, and improving combat efficiency and safety. This mode is suitable for scenarios where there is a balance between recoil efficiency and shock wave suppression.

[0017] (3) Through modular structural design, the present invention realizes flexible combination and replacement of the muzzle brake body, shell and end cap. After continuous firing, the muzzle temperature may rise rapidly, but the shell can maintain a low temperature, providing effective heat insulation protection, and the shell can be replaced when necessary, thereby effectively avoiding equipment damage caused by overheating and enhancing the long-term combat capability of the weapon system.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] The following first introduces the embodiments of the present application in conjunction with the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 The present invention provides a dual-mode combined muzzle brake, which is composed of a plurality of components, including a brake body 1, an outer shell 2 and an end cap 3. The brake body 1 includes a brake end 4, a positioning section 5, a first exhaust hole 6, a boss 7, a second exhaust hole 8, an inner shell 9 and a connecting section 10; the end cap 3 includes an end cap end 13, a front end face 14, and a central bullet hole 15; the brake end 4, the positioning section 5, the inner shell 9 and the connecting section 10 are connected in sequence, and the positioning section 5 is used to position with the rear end face of the outer shell 2. The end cap 3 is provided with an end cap end 13, a front end face 14 and a central bullet hole 15 in sequence from back to front along the axial direction, and the end cap end 13 is provided with an internal thread; the outer diameter of the front end face 14 gradually decreases, and the outer diameter of the rear end is consistent with the outer diameter of the connecting section 10; one end of the central bullet hole 15 is a projectile outlet.

[0025] The end 4 of the muzzle brake is provided with an internal thread, which can be threadedly connected with the external thread of the gun barrel head. The connecting section 10 of the muzzle brake body 1 is provided with an external thread, which is threadedly connected with the internal thread of the end cap end 13.

[0026] On the outer surface of the inner shell 9 of the muzzle brake body 1, near the position of the positioning section 5, a first exhaust hole 6 is symmetrically arranged, and a pair of bosses 7 parallel to the axis of the muzzle brake body 1 and symmetrically arranged up and down are arranged between the left and right first exhaust holes 6; a pair of symmetrical grooves 11 are arranged on the upper and lower end surfaces of the center hole of the outer shell 2, and the grooves 11 are symmetrically distributed about the center axis. The inner diameter of the outer shell 2 is equal to the outer diameter of the inner shell 9, and the grooves 11 of the outer shell 2 cooperate with the bosses 7 to form a nested connection pair.

[0027] Preferably, three rows of oblique side hole groups 12 are arranged parallel to the axis on the left and right sides of the shell 2, and these oblique side hole groups 12 are symmetrically distributed relative to the axis of the muzzle brake. Each row of oblique side hole groups 12 consists of five rectangular holes, and these rectangular holes are evenly spaced along the axial direction of the shell 2, forming a total of 15 oblique side holes. The oblique side hole group 12 is inclined toward the muzzle brake end 4, and the angle between the oblique side hole group 12 and the axis of the muzzle brake body 1 is 150°.

[0028] The inner shell of the muzzle brake body 1 is provided with a first exhaust hole 6 and a second exhaust hole 8 which are perpendicular to the axial direction of the body, and both are side holes projected as rectangles, and the second exhaust hole 8 is located near the connecting section 10. In order to avoid blockage or uneven distribution of airflow when flowing through the muzzle brake, the size of the first exhaust hole 6 is larger than that of the second exhaust hole 8, ensuring that the channel of the oblique side hole group 12 is precisely docked with the first exhaust hole 6 and the second exhaust hole 8 of the muzzle brake body 1 in the axial direction of the center hole of the outer shell 2.

[0029] During use, the use of the housing 2 can be selected according to actual work requirements. The holes of the oblique side hole group 12 are precisely connected with the first exhaust hole 6 and the second exhaust hole 8 of the muzzle brake body in the axial direction of the housing center hole, which can effectively reduce the recoil force and optimize the airflow distribution to meet different use requirements.

[0030] In the first working mode, when the shell 2 is not used, the recoil brake body 1 and the end cap 3 form a complete recoil brake device. At this time, when the artillery is fired, most of the gunpowder gas is discharged through the first exhaust hole 6 and the second exhaust hole 8 of the recoil brake body, thereby minimizing the gas flow of the central bullet hole 15, thereby achieving the maximum recoil efficiency of the recoil brake. Although the shock wave in the muzzle area is more harmful at this time, this mode is suitable for combat scenarios with limited costs and the need to quickly release gas to reduce recoil.

[0031] In the second working mode, the shell 2, the recoil brake body 1 and the end cap 3 form a complete recoil brake device. At this time, the oblique side hole group 12 of the shell 2 matches the first exhaust hole 6 and the second exhaust hole 8 of the recoil brake body 1, which can guide the gunpowder gas to accelerate outflow to the rear side of the gun. Compared with the first working mode, the second working mode more effectively utilizes the reaction force of the gas, thereby significantly reducing the recoil. Even when the muzzle temperature rises due to continuous firing, the shell can maintain a low temperature, provide heat insulation protection, and can be replaced when necessary to ensure continuous combat effectiveness. In addition, the dispersed design of the airflow avoids the concentration of local impact force, further reduces the recoil force, makes the diffusion of flames and smoke more stable, avoids the concentration of shock waves, reduces local hazards, improves the visual conditions after firing, reduces visual interference, and helps operators respond more quickly. Therefore, the second working mode is suitable for combat scenarios that require a balance between recoil efficiency and shock wave suppression.

[0032] The above-described embodiments of the present application do not constitute a limitation on the protection scope of the present application.
