Description

Technical Field

[0001] The invention relates to the technical field of pistol auxiliary equipment, in particular to a gun-fire warning safety device. Background Art

[0002] The police use weapons in accordance with the law in four forms: armed alert, warning with a gun, warning with a gun, and shooting. Among them, "warning with a gun" means that when the police find that a criminal suspect is about to commit or is committing a violent crime, if verbal warnings are ineffective or there is no time to give a verbal warning, they can fire a warning shot towards the sky or other safe directions according to the situation. Firing a warning shot is a legal and effective means for the police to deter criminals on the spot. However, there are many problems in reality: when firing a warning shot in a downtown area, it is not easy to find a safe direction for firing a warning shot. Choosing the road surface, wall, etc. may cause ricochet and injure people; there may be stones and other objects hidden in the green belt, which may also cause stray bullets to injure people; if you choose to fire a shot into the sky, the muzzle is often too far away because the police are more likely to use their eyes to pay attention to the criminal suspect, which can easily cause harm to residents in surrounding buildings. For example, on June 8, 2016, in Foshan, Guangdong, when the police were handling a police incident of armed group fighting, they fired a warning shot, causing a man who was watching the excitement on the balcony of the fifth floor of a nearby building to be shot and eventually died due to ineffective rescue. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a bullet-sparking buffer, which is helpful to alleviate the entanglement problem of the muzzle pointing of a warning shot and is helpful to significantly reduce the occurrence of accidental injuries.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a gun warning safety device comprises an energy absorbing tube, a muzzle fixing part is provided on one end of the energy absorbing tube, and the muzzle fixing part is used to be sleeved on the outer periphery of the muzzle of a firearm; the inner cavity of the energy absorbing tube constitutes an energy absorbing channel connected with the inner cavity of the barrel of the firearm, an energy absorbing block for buffering the impact of bullets is installed in the end of the energy absorbing tube away from the muzzle, a blocking structure is fixedly provided on the side of the energy absorbing tube away from the muzzle, a plurality of circumferentially arranged pressure discharge ports are provided on the tube wall of the energy absorbing tube on the side of the energy absorbing block close to the muzzle, and air barrier plates are respectively covered on the outer wall of the energy absorbing tube corresponding to the pressure discharge ports, and the end of the air barrier plate close to the muzzle is connected to the energy absorbing tube.

[0005] As a preferred technical solution, a muzzle connecting tube is threadedly installed on one end of the energy absorbing tube close to the muzzle, and the inner cavity of the muzzle connecting tube and the inner tube of the energy absorbing tube are connected to the inner cavity of the barrel of the firearm; the muzzle fixing part is provided on the muzzle connecting tube.

[0006] As a preferred technical solution, a muzzle connecting internal thread is provided on the inner wall of one end of the energy absorbing tube close to the muzzle, and a muzzle connecting external thread matching the muzzle connecting internal thread is provided on the outer periphery of the muzzle connecting tube; a barrier plate clamping protrusion is provided on the muzzle connecting tube at a side of the muzzle connecting external thread away from the energy absorbing tube, and a barrier plate base ring is mounted on the muzzle connecting tube at a side of the barrier plate clamping protrusion close to the energy absorbing tube, and the barrier plate clamping protrusion and the energy absorbing tube jointly clamp the barrier plate base ring; the gas barrier plate is integrally connected to the outer periphery of the barrier plate base ring.

[0007] As a preferred technical solution, a circumferential limiting notch is provided between the connecting portions of two adjacent air barrier plates and the barrier plate base ring, and a circumferential limiting protrusion extending to the circumferential limiting notch is fixedly provided on the energy absorbing cylinder.

[0008] As a preferred technical solution, the thickness of the gas barrier sheet is increased in a direction away from the barrier sheet base ring.

[0009] As a preferred technical solution, the gas barrier plate and the barrier plate base ring are made of soft aluminum or copper.

[0010] As a preferred technical solution, the muzzle fixing portion includes at least two muzzle clamping pieces, and the muzzle clamping pieces are clamped and fixed together on the outer periphery of the muzzle of the firearm.

[0011] As a preferred technical solution, a resistance-enhancing structure is provided on the inner wall of the muzzle fixing portion.

[0012] As a preferred technical solution, a magnetic fixing structure is also provided on the energy absorbing cylinder.

[0013] As a preferred technical solution, the cross-sectional area of ​​the inner cavity of the energy absorbing tube is increased in the direction away from the muzzle.

[0014] Due to the adoption of the above technical scheme, the gun warning safety device includes an energy absorbing tube, one end of which is provided with a muzzle fixing part, and the muzzle fixing part is used to be sleeved on the outer periphery of the muzzle of a firearm; the inner cavity of the energy absorbing tube constitutes an energy absorbing channel connected with the inner cavity of the barrel of the firearm, an energy absorbing block for buffering the impact of bullets is installed in the end of the energy absorbing tube away from the muzzle, a blocking structure is fixedly provided on the side of the energy absorbing tube away from the muzzle, a plurality of circumferentially arranged pressure discharge ports are provided on the tube wall of the energy absorbing tube on the side of the energy absorbing block close to the muzzle, and air barrier plates are respectively covered on the outer wall of the energy absorbing tube corresponding to the pressure discharge ports, and the end of the air barrier plate close to the muzzle is connected to the energy absorbing tube. When a warning shot is fired, the ejected bullet impacts the energy absorbing block, which cushions the impact of the bullet by its own good flexibility, reducing the kinetic energy of the bullet; the reduced kinetic energy of the bullet generates a reaction force on the energy absorbing block, which exceeds the fixing force of the muzzle fixing part, so that the energy absorbing tube as a whole moves away from the muzzle of the firearm. Since the overall mass of the energy absorbing tube is much larger than that of the bullet, the initial velocity that can be generated by the impact of the bullet is relatively small, and thus the flight distance is short. In addition, the gunpowder gas generated when the gun is fired will also rush into the energy absorbing tube and be discharged to the side through the pressure discharge port. The air barrier is connected to the energy absorbing tube near one end of the muzzle, causing the air barrier to open like a blooming petal. The opened air barrier will increase the air resistance of the overall flight of the energy absorbing tube, further reducing the flight distance. Therefore, the present invention can buffer the flying bullet and utilize an energy-absorbing tube with a shorter flying distance, so that the police do not need to worry too much about the unsafe factors of the muzzle pointing when firing a warning shot. This helps to alleviate the entanglement problem of the muzzle pointing when firing a warning shot and helps to significantly reduce the occurrence of accidental injuries.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0018] like Figures 1 to 5 As shown in common, the gun-fire warning safety device comprises an energy-absorbing tube 1, and a muzzle fixing portion 21 is provided on one end of the energy-absorbing tube 1, and the muzzle fixing portion 21 is used to be sleeved on the outer periphery of the muzzle of the firearm 9, and a detachable connection with the firearm 9 is formed by this sleeve. When in use, the muzzle fixing portion 21 is sleeved on the outer periphery of the muzzle to form an installation. This sleeve operation is convenient, and can be quickly completed during the police holding a gun on alert or the process of issuing a gun for warning. After the sleeve, even if the muzzle of the user droops when running, the energy-absorbing tube 1 will not be separated from the gun body, ensuring the stability of use. When firing a gun, the energy-absorbing tube 1 can be driven by only the bullet to move in the direction away from the gun body, so as to achieve the purpose of automatically separating the energy-absorbing tube 1 from the gun body, which not only avoids the occurrence of gunpowder explosion, but also facilitates the user to sequentially perform the possible shooting action. The muzzle fixing portion 21 of the present embodiment includes at least two muzzle clamping pieces 22, which are clamped and fixed together on the outer periphery of the muzzle of the firearm 9. The above-mentioned sleeve connection effect is formed by clamping multiple muzzle clamping pieces 22.

[0019] Preferably, a resistance increasing structure is provided on the inner wall of the muzzle fixing part 21 to further improve the connection stability at the muzzle after the sleeve connection. The resistance increasing structure can be realized by processing a rough contact surface on the inner wall of the muzzle fixing part 21, or by attaching a frosted foam layer on the inner wall of the muzzle fixing part 21, etc., which is not limited here.

[0020] Preferably, the energy absorbing tube 1 is also provided with a magnetic fixing structure 3, which further improves the fixed connection between the present embodiment and the muzzle position by increasing the magnetic attraction force, and the magnetic attraction force can also be overcome by the impact force of the bullet. There is no rigid blocking structure when the energy absorbing tube 1 automatically separates from the gun body, which is beneficial to ensure that the energy absorbing tube 1 automatically separates from the gun body under the impact of the bullet.

[0021] Conventionally, the gun body of the firearm 9 includes a fixed part 91, a sleeve 92, a barrel 93, etc., and the sleeve 92 is sleeved outside the barrel 93. When the gun is fired, the bullet is ejected from the barrel 93 by the thrust of the gunpowder, and the gunpowder pressure pushes the sleeve 92 to slide in the opposite direction relative to the barrel 93, and the next bullet is automatically loaded. This embodiment is fixedly connected at the muzzle, and is actually mostly or entirely connected to the sleeve 92. Therefore, in actual setting, the end face of the energy absorbing tube 1 close to the muzzle is preferably provided with a connection positioning surface 24 that is positioned against the end face of the sleeve 92, so as to promote the muzzle fixing part 21 to be able to contact through this plane when it is sleeved to the outer periphery of the muzzle, so that this embodiment can be installed faster and more accurately.

[0022] The inner cavity of the energy absorbing tube 1 constitutes an energy absorbing channel connected to the inner cavity of the barrel 93 of the firearm 9. After firing, the bullet flies into the inner cavity of the energy absorbing tube 1. An energy absorbing block 4 for buffering the impact of the bullet is installed in the end of the energy absorbing tube 1 away from the muzzle. A blocking structure 41 is fixedly provided on the energy absorbing tube 1 on the side of the energy absorbing block 4 away from the muzzle. The bullet flying into the energy absorbing tube 1 eventually impacts the energy absorbing block 4. The energy absorbing block 4 relies on its own good flexibility to buffer the impact of the bullet by deformation and reduce the kinetic energy of the bullet. In this buffering process, the blocking structure 41 prevents the bullet from being further ejected due to its rigidity, and the reduced kinetic energy of the bullet generates a reaction force on the energy absorbing block 4. The reaction force is simultaneously transmitted to the energy absorbing tube 1 through the blocking structure 41, so that the energy absorbing tube 1 can overcome the fixing force of the muzzle fixing part 21 and the magnetic attraction of the magnetic attraction fixing structure 3, and detach from the gun body. Preferably, the energy absorbing block 4 is made of Kevlar bulletproof material. Preferably, the blocking structure 41 is a blocking cover threadedly installed in the port of the energy absorbing cylinder 1 , thereby facilitating the installation of the energy absorbing block 4 in the energy absorbing cylinder 1 .

[0023] The energy absorbing tube 1 is provided with a plurality of circumferentially arranged pressure relief ports 11 on the tube wall located on the side of the energy absorbing block 4 close to the muzzle, and the outer wall of the energy absorbing tube 1 is covered with gas barrier sheets 5 corresponding to the pressure relief ports 11, and the end of the gas barrier sheet 5 close to the muzzle is connected to the energy absorbing tube 1. When firing a gun, the bullet is ejected first and the pistol sleeve 92 then retreats, and the gunpowder gas that drives the bullet to be ejected after firing the gun will also rush into the energy absorbing tube 1 first; this embodiment forms an effective pressure relief for the gunpowder gas by setting the pressure relief ports 11 to avoid the occurrence of chamber explosion; and when the energy absorbing tube 1 is separated from the gun body, the sleeve 92 also slides in the opposite direction, forming a larger release space between the two, and the chamber explosion can be further avoided.

[0024] The high-pressure airflow discharged from the pressure discharge port 11 will impact the air barrier sheet 5. Since the air barrier sheet 5 is connected to the energy absorbing tube 1 at the end close to the muzzle, the end away from the muzzle will flip around the end close to the muzzle, and the multiple air barrier sheets 5 will jointly form an opening action like blooming petals. Therefore, the air barrier sheet 5 produces two air blocking effects. One is that after the energy absorbing tube 1 is separated from the gun body, the contact area between the energy absorbing tube 1 and the air in the flight direction is increased, which plays a role in increasing air resistance and is conducive to further reducing the flight distance of the energy absorbing tube 1. The other is that during the opening process, the air barrier sheet 5 can prevent the outflowing airflow from rushing towards the user, thereby improving the safety of use.

[0025] Preferably, the cross-sectional area of ​​the inner cavity of the energy absorbing tube 1 is increased in the direction away from the muzzle, which forms a gradual expansion of the inner cavity of the energy absorbing tube 1 in the direction away from the muzzle, which can buffer the gunpowder gas pressure to a certain extent and further avoid the occurrence of chamber explosion. Preferably, the thickness of the gas barrier sheet 5 is increased in the direction away from the barrier sheet base ring 51. The increased thickness can form a stronger impact resistance, preventing the sheet shape of the gas barrier sheet 5 from being destroyed by the high-pressure airflow, and the relatively weak connection can facilitate the plastic deformation of the gas barrier sheet 5 under the high-pressure impact, and finally achieve the opening effect required by this embodiment.

[0026] The end of the energy absorbing tube 1 near the muzzle of the present embodiment is threadedly mounted with a muzzle connecting tube 2, and the inner cavity of the muzzle connecting tube 2 and the inner tube of the energy absorbing tube 1 are connected to the inner cavity of the barrel 93 of the firearm 9; the muzzle connecting tube 2 is provided with the muzzle fixing portion 21, and correspondingly, the muzzle connecting tube 2 is provided with a connecting positioning surface 24 that is positioned against the end surface of the sleeve 92. Since the muzzle positions and shapes of different types of pistols are different, different muzzle fixing portions 21 need to be designed and manufactured for different types of pistols; the present embodiment can conveniently connect the muzzle connecting tube 2 and the muzzle fixing portion 21 required by different types of pistols to the energy absorbing tube 1 through the separate arrangement of the muzzle connecting tube 2 and the energy absorbing tube 1, thereby improving the flexibility of use.

[0027] In this embodiment, the inner wall of the end of the energy absorbing tube 1 close to the muzzle is provided with a muzzle connection internal thread, and the outer periphery of the muzzle connection tube 2 is provided with a muzzle connection external thread matched with the muzzle connection internal thread, so as to form a threaded connection. The muzzle connection tube 2 is provided with a barrier plate clamping protrusion 23 at the side of the muzzle connection external thread away from the energy absorbing tube 1, and the muzzle connection tube 2 is provided with a barrier plate base ring 51 at the side of the barrier plate clamping protrusion 23 close to the energy absorbing tube 1, and the barrier plate clamping protrusion 23 and the energy absorbing tube 1 are used to clamp the barrier plate base ring 51 together; the outer periphery of the barrier plate base ring 51 is integrally connected with the gas barrier plate 5.

[0028] After the energy absorbing tube 1 and the muzzle connecting tube 2 are threadedly connected, the barrier base ring 51 is clamped between the two to achieve the connection between the end of the gas barrier 5 close to the muzzle and the energy absorbing tube 1, which is conducive to the simplification of the overall structure of this embodiment. Preferably, a circumferential limiting notch 52 is provided between the connecting parts of two adjacent gas barrier sheets 5 and the barrier base ring 51, and a circumferential limiting protrusion 53 extending to the circumferential limiting notch 52 is fixedly provided on the energy absorbing tube 1. The circumferential limiting effect formed by the circumferential limiting protrusion 53 and the circumferential limiting notch 52 enables the gas barrier sheet 5 to remain at the corresponding pressure relief port 11 during the threaded connection between the muzzle connecting tube 2 and the energy absorbing tube 1, thereby ensuring the gas blocking effect during the subsequent firing process.

[0029] In this embodiment, a magnetic ring is also mounted on the muzzle connection tube 2 at the side of the barrier clamping protrusion 23 close to the energy absorbing tube 1, and the magnetic ring also serves as the magnetic attraction fixing structure 3. Therefore, the muzzle connection tube 2 and the muzzle fixing part 21 are preferably made of steel material to generate a magnetic attraction effect with the muzzle position through magnetic conductivity; and the gas barrier 5 and the barrier base ring 51 are preferably made of soft aluminum or copper material, which has good plastic deformation ability and is not magnetic, and the opening action is not affected by magnetic force.

[0030] This embodiment can be fixed at the muzzle of the firearm 9 by sleeve connection during the process of holding a gun for alert and issuing a gun for warning. When firing a gun for warning, the flying bullet impacts on the energy absorbing block 4, and the energy absorbing block 4 buffers the impact of the bullet by its own good flexibility, reducing the kinetic energy of the bullet; the reduced kinetic energy of the bullet generates a reaction force on the energy absorbing block 4, and the reaction force exceeds the fixing force of the muzzle fixing part 21, so that the energy absorbing tube 1 as a whole moves away from the muzzle of the firearm 9, that is, the energy absorbing tube 1 buffers the impact of the bullet through the energy absorbing block 4 after the bullet is fired, and is separated from the firearm 9. Since the overall mass of the energy absorbing tube 1 is much larger than that of the bullet, the initial speed that can be generated by the impact of the bullet is small, and thus the flight distance is small. In addition, the gunpowder gas generated when firing a gun will also rush into the energy absorbing tube 1 and be discharged to the side through the pressure discharge port 11. The gas barrier 5 is connected to the energy absorbing tube 1 near the muzzle, so that the gas barrier 5 opens like a blooming petal. The opened air-blocking sheet 5 will increase the air resistance of the energy-absorbing tube 1 as a whole, further reducing the flight distance. Thus, this embodiment can buffer the flying bullet and utilize the energy-absorbing tube 1 with a smaller flight distance, so that the police do not need to be overly concerned about the unsafe factors of the muzzle pointing when firing a warning shot, thereby alleviating the entanglement problem of the muzzle pointing when firing a warning shot, and significantly reducing the occurrence of accidental injuries. This embodiment has a simple structure and low cost, and can be made into a disposable consumable, further improving the convenience of the use process.
