Description

Technical Field

[0001] This application relates to the field of rifle accessories, and in particular to a muzzle brake and a rifle. Background Technology

[0002] A muzzle brake is a device installed at the muzzle of a firearm. Its main function is to reduce recoil and muzzle rise during firing by controlling and guiding the propellant gases ejected from the muzzle. It is widely used in weapon systems such as rifles, machine guns, and artillery to improve shooting accuracy and controllability.

[0003] In related technologies, the drawback of muzzle brakes is that they are not effective in suppressing muzzle rise and vibration of rifles with high recoil, such as sniper rifles, resulting in large muzzle rise, which is not conducive to the shooter's multi-target shooting and quick search for the next target. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a muzzle brake and rifle that can improve the suppression of muzzle rise and vibration.

The muzzle brake body has a central ballistic trajectory that runs through the front and back. Multiple pairs of chambers are arranged sequentially from front to back on both sides of the central ballistic trajectory. Each pair of chambers is arranged opposite to each other and is inclined in the opposite direction to the muzzle. The side wall of the muzzle brake body has an air hole that is inclined towards the end of the rifle. The air hole is connected to the chamber to allow the airflow generated when the bullet is fired to pass through the chamber and be ejected from the air hole.

[0033] Reference Figure 1 and Figure 2As shown, a muzzle brake, installed at the muzzle of a rifle, includes a locking band 100 and a muzzle brake body 200. The locking band 100 is used to fix the muzzle to the rifle. A connecting portion 210 is provided at the end of the muzzle brake body 200, which is detachably connected to the locking band 100. The muzzle brake body 200 has a central ballistic trajectory 220 extending from front to back. Multiple pairs of chambers 230 are arranged sequentially on both sides of the central ballistic trajectory 220 from front to back. Each pair of chambers 230 is arranged opposite to each other and inclined in opposite directions towards the muzzle. The side wall of the muzzle brake body 200 has air holes 240 inclined towards the end of the rifle. The air holes 240 communicate with the chambers 230 to allow airflow generated during bullet firing to pass through the chambers 230 and exit from the air holes 240.

[0034] In this embodiment, the muzzle brake body 200 is fixed to the muzzle of the rifle by a locking clamp 100. Multiple pairs of chambers 230 are arranged sequentially from front to back on both sides of the central ballistic trajectory 220 of the muzzle brake body 200. Each pair of chambers 230 is arranged opposite to each other and is inclined in the opposite direction to the muzzle. Multiple M-shaped airflow chambers are formed inside the muzzle brake. When the rifle is fired, the gunpowder gas is guided through the M-shaped airflow chambers and ejected obliquely to the rear through the inclined air holes 240 on the side. This application forms multiple airflows that are ejected obliquely to the rear through multiple airflow chambers and air holes 240. By utilizing the principle of conservation of momentum, a forward reaction force is generated, which can improve the suppression effect of muzzle jump and vibration.

[0035] Specifically, in this embodiment, the locking clamp 100 is a ring-shaped clamp structure, fitted onto the rifle muzzle and fixed by the fastening bolt 101. Reinforcing ribs are provided around the screw holes on both sides of the bottom of the locking clamp 100 to improve overall strength. A connecting part 210 is provided at the end of the muzzle brake body 200. The connection between the connecting part 210 and the locking clamp 100 fixes the muzzle brake body 200 to the rifle muzzle, and the bullet is fired through the muzzle brake body 200. Exemplarily, in this embodiment, the connecting part 210 can be inserted into the locking clamp 100 and fixed to it by a snap-fit. Of course, in addition to snap-fit, threads can also be provided on the locking clamp 100 and the connecting part 210, allowing the snap-fit ​​part 210 to be fixed to the locking clamp 100 by screwing. Alignment grooves are provided at the ends of both the connecting part 210 and the locking clamp 100 to align them after insertion, ensuring precise alignment of the central ballistic trajectory 220 with the barrel.

[0036] It should be noted that the reference Figure 3As shown, the muzzle brake body 200 has a central ballistic trajectory 220 running through it from front to back. The central ballistic trajectory 220 is the path the bullet travels when it is fired. During firing, the bullet is ejected from the front end of the muzzle brake body 200 along the central ballistic trajectory 220. The central ballistic trajectory 220 is precisely aligned with the barrel to ensure that the bullet can be ejected from the barrel without obstruction. In this embodiment, multiple pairs of chambers 230 are arranged sequentially from front to back on both sides of the central ballistic trajectory 220. Each pair of chambers 230 is arranged opposite each other and tilted in the opposite direction to the muzzle, thereby forming an M-shaped airflow chamber. Multiple M-shaped airflow chambers are arranged sequentially along the central ballistic trajectory 220 to form a stepped gas expansion space. After the gunpowder gas enters the chamber 230, it impacts the reflective surface in sequence and expands. It is then discharged to the side and rear through the side air holes 240. The forward reaction force is generated by utilizing the principle of conservation of momentum to counteract the recoil generated during firing. Therefore, the recoil can be significantly reduced and the firing stability can be improved.

[0037] In some embodiments, the tilt angle between chamber 230 and central trajectory 220 is 30 to 60 degrees.

[0038] In this embodiment, by setting the tilt angle between the chamber 230 and the central ballistic trajectory 220 to 30 to 60 degrees, the effect of suppressing muzzle jump and vibration can be further improved.

[0039] It should be noted that, according to tests, if the tilt angle between the chamber 230 and the central trajectory 220 is less than 30 degrees, the effect of suppressing horizontal muzzle shake during firing is poor; if the tilt angle between the chamber 230 and the central trajectory 220 is greater than 60 degrees, the effect of suppressing recoil during firing is poor. Therefore, this embodiment limits the tilt angle between the chamber 230 and the central trajectory 220 to 30 to 60 degrees, which can balance the suppression of muzzle horizontal shake and recoil, and further improve the overall effect of suppressing muzzle jump and vibration.

[0040] In some embodiments, the top of the brake body 200 is a planar structure.

[0041] In this embodiment, the top of the muzzle brake body 200 is a flat structure, which allows a level 300 to be placed on top of the muzzle brake, improving the functionality of the rifle.

[0042] In related technologies, the recoil brake has a cylindrical structure, and items cannot be placed on its top. (See reference...) Figure 5As shown, this application designs the top of the muzzle brake body 200 as a flat structure, allowing a level to be placed on top of the muzzle brake. During firing, the level primarily helps the shooter ensure the weapon is in an ideal level position, avoiding aiming errors caused by weapon tilt. By using the level, the shooter can ensure that the firearm and aiming device are in a horizontal position during firing. This helps reduce aiming errors caused by weapon tilt, ensuring the bullet flies along the expected trajectory. Placing the level on top of the muzzle brake body 200 allows the shooter to observe the level while maintaining an aiming posture, without needing to rotate the viewing angle, thus improving the reliability of firing.

[0043] In some embodiments, the outer wall of the connecting portion 210 is provided with one or more transversely arranged protruding rings 211, and the inner wall of the locking clamp 100 is provided with a groove 110 that matches and engages with the protruding rings 211.

[0044] In this embodiment, by providing a protruding ring 211 on the outer wall of the connecting part 210 and a groove 110 on the inner wall of the locking band 100, after the locking band 100 is inserted into the connecting part 210, the muzzle brake body 200 is firmly fixed on the locking band 100 through the snap-fit ​​of the protruding ring 211 and the groove 110, preventing loosening and slippage, improving the structural stability of the muzzle brake during installation, and ensuring that the concentricity of the muzzle brake and the barrel remains consistent, without affecting the accuracy / dispersion of the sniper rifle.

[0045] In some embodiments, the end of the connecting portion 210 is provided with one or more longitudinally arranged first slots.

[0046] In this embodiment, one or more longitudinally arranged first slots are provided at the end of the connecting part 210. When the connecting part 210 is inserted into the locking clamp 100 and locked, the first slots can make the connecting part 210 slightly shrink, so that the entire locking clamp 100 is evenly stressed when it is tightened, and the concentricity of the muzzle brake and the barrel is kept consistent, so as not to affect the accuracy / dispersion of the sniper rifle.

[0047] In some embodiments, the first slot includes a plurality of first sub-slots 212 and a plurality of second sub-slots 213, the first sub-slots 212 and the second sub-slots 213 being arranged alternately in sequence, the end of the first sub-slot 212 being an open structure, and the end of the second sub-slot 213 being a closed structure.

[0048] In this embodiment, the first slot is configured as multiple first sub-slots 212 and multiple second sub-slots 213, with the first sub-slots 212 and second sub-slots 213 arranged alternately. The ends of the first sub-slots 212 are open structures, while the ends of the second sub-slots 213 are closed structures. This can further improve the stability of the structure during muzzle brake installation, ensuring that the concentricity of the muzzle brake and the barrel remains consistent, without affecting the accuracy / dispersion of the sniper rifle.

[0049] refer to Figure 2 As shown, the end of the first sub-slot 212 is an open structure, meaning that the first sub-slot 212 is an open groove whose end is connected to the outside; the end of the second sub-slot 213 is a closed structure, meaning that the second sub-slot 213 is a closed groove whose end is not connected to the outside. The first sub-slot 212 and the second sub-slot 213 are spaced apart, which can improve the uniformity of force when the locking hoop 100 is tightened, and at the same time ensure the structural strength of the connecting part 210, avoiding damage to the connecting part 210 due to pressure.

[0050] In some embodiments, the top of the locking clamp 100 has one or more second slots 120.

[0051] In this embodiment, one or more second slots 120 are provided on the top of the locking band 100, which can reduce weight and reduce the top stress when the locking band 100 is tightened, so that the locking band 100 can be more firmly locked to the muzzle of the rifle.

[0052] For example, in this embodiment, three second slots 120 are provided on the top of the locking band 100. Of course, one, two or more second slots 120 can also be provided as needed.

[0053] In some embodiments, the inner wall of the connecting portion 210 is provided with anti-slip texture 214.

[0054] In this embodiment, anti-slip texture 214 is provided on the inner wall of the connecting part 210. When the connecting part 210 is inserted into the locking clamp 100, its inner wall abuts against the outer wall of the barrel. The anti-slip texture 214 can increase the friction between the inner wall of the connecting part 210 and the outer wall of the barrel, prevent slippage, and further improve the stability of the structure when the muzzle brake is installed.

[0055] In some embodiments, the air vent 240 is angled toward the end of the rifle and tilted upwards, and / or;

[0056] The upper diameter of pore 240 is larger than the lower diameter.

[0057] In this embodiment, the air hole 240 is set to be tilted towards the end of the rifle and tilted upward, so that the airflow generated by shooting is discharged obliquely upward, which can further improve the suppression effect of muzzle rise.

[0058] In this embodiment, the upper diameter of the air hole 240 is set to be larger than the lower diameter. When firing, more airflow generated by the bullet will be ejected from the upper end of the air hole 240, which can further improve the suppression effect of muzzle sway.

[0059] It should be understood that the air port 240 can be set to be tilted towards the end of the rifle and tilted upwards, and the upper diameter of the air port 240 can be larger than the lower diameter. This can be set simultaneously or one of them can be set.

[0060] This application also relates to a rifle, see reference Figure 4 As shown, the muzzle brake of the rifle described above is installed at the front of the muzzle.

[0061] Specifically, the rifle can be a sniper rifle, an assault rifle, or other types of rifles.

[0062] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
