Description

Technical Field

[0001] This invention relates to the field of firearms, and in particular to a pneumatic projectile-launching gun. Background Technology

[0002] A pneumatic launcher is a type of riot control device. This device uses high-pressure gas as a power source to launch spherical projectiles such as capsaicin tear gas, chromic marker grenades, and rubber bullets for non-lethal attacks.

[0003] Currently, non-lethal strike equipment mainly consists of hand-thrown and jet-type devices, which have short striking ranges and poor firing accuracy. Large-caliber kinetic energy strike equipment uses gunpowder gas as a power source, resulting in high ammunition manufacturing and procurement costs. In contrast, pneumatic launchers use high-pressure gas as a power source, with compressed air or compressed carbon dioxide gas as raw materials. They can be refilled and reused, are simple to manufacture, have low costs, and feature long range, multiple types of ammunition, and reliable mechanism operation, resulting in good riot control effects. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pneumatic projectile gun that uses high-pressure gas as the power source for firing, and is capable of firing spherical projectiles such as capsaicin tear gas, dye marking projectiles, and rubber bullets.

[0005] The objective of this invention is achieved as follows:

[0006] A pneumatic projectile-launching gun includes a receiver assembly (1), a firing tube (2) connected to the front end of the receiver assembly (1), a high-pressure gas cylinder (301) connected to the rear end of the receiver assembly (1), a connecting channel, a push tube (104), a recoil spring (105), and a cylinder (106) provided in the middle of the receiver assembly (1), and a firing mechanism (4) and a feeding mechanism (5) installed at the lower part of the receiver assembly (1).

[0007] The front end of the connecting channel is connected to the launching tube (2), the middle part of the connecting channel is connected to the feeding mechanism (5), and the rear end of the connecting channel is slidably engaged with the front end of the pushing tube (104). The feeding mechanism (5) is used to transport the projectile to the connecting channel, and the front end of the pushing tube (104) is used to push the projectile into the launching tube (2) to launch the projectile.

[0008] The cylinder (106) is connected to the high-pressure gas cylinder (301). The cylinder (106) is used to contain high-pressure gas. The front end of the cylinder (106) is provided with a gas guide tube (112). The inner hole of the push tube (104) is a stepped hole. A tapered body (115) extending backward is provided in the middle of the stepped surface of the inner hole of the push tube (104). There is a gap between the tapered body (115) and the inner wall of the large end of the push tube (104). A gas guide hole (114) is provided at the edge of the stepped surface of the inner hole of the push tube (104). The gas guide hole (114) allows the large end and small end of the push tube (104) to pass through. The conical body (115) of the projectile pusher tube (104) extends into the gas cylinder (112) and can slide back and forth. The tail end of the projectile pusher tube (104) is connected to the limiting plate (113) by a thread. The recoil spring (105) is sleeved on the projectile pusher tube (104). The front end of the recoil spring (105) acts on the receiver component (1), and the tail end of the recoil spring (105) acts on the limiting plate (113). The recoil spring (105) is used to drive the projectile pusher tube (104) back to its original position after the projectile is launched. After the projectile pusher tube (104) returns to its original position, it relies on the thick end of the conical body (115) to seal the cylinder (106).

[0009] The launching mechanism (4) includes a launcher base (401), on which a trigger (402) and a sear (403) are mounted. The trigger (402) is used to control the movement of the sear (403), and the sear (403) is used to prevent the push tube (104) from moving forward or to release the push tube (104). After the push tube (104) is released, high-pressure gas pushes the push tube (104) forward to launch the projectile.

[0010] When the sear (403) releases the limiting plate (113), the push tube (104) is pushed to the forward position under the action of the high pressure gas in the cylinder (106). The cone (115) forms a gap with the air guide tube (112) of the cylinder (106). The air guide hole (114) is connected to the air guide tube (112) of the cylinder (106) through the gap. At this time, the launch tube (2), the air guide hole (114) of the push tube (104), and the air guide tube (112) of the cylinder (106) form a gas passage to connect with the outside. The high pressure gas in the cylinder (106) is released, the projectile is launched, and then the air pressure drops instantly and reaches equilibrium with the external standard atmospheric pressure.

[0011] When the air pressure in the cylinder (106) decreases, the gas pressure on the push tube (104) and the limiting plate (113) is less than the spring force of the recoil spring (105). The spring force of the recoil spring (105) pushes the push tube (104) and the limiting plate (113) to move backward and return to their original positions. When the cone (115) of the push tube (104) moves backward, the gap between the cone (115) and the air guide cylinder (112) gradually decreases until it is closed. After the push tube (104) and the limiting plate (113) return to their original positions, the sear (403) of the launching mechanism (4) moves upward under the action of the sear spring (404) and blocks the limiting plate (113), preventing the push tube (104) from moving forward. After the sealing, the air pressure in the cylinder (106) gradually increases and reaches the set launching value.

[0012] Preferably, the receiver component (1) includes an upper receiver (101) and a lower receiver (102), which are fixedly connected; the upper receiver (101) has a launch tube connection thread (103) at its front end and a gas cylinder connection thread (107) at its rear end; a Picatinny rail interface (108) is provided on the upper part of the upper receiver (101); a push tube (104) and a recoil spring (105) are provided in the middle of the upper receiver (101); and the lower receiver (102) is equipped with a launching mechanism (4) and a feeding mechanism (5).

[0013] Preferably, the lower part of the upper casing (101) is provided with a launch mechanism interface (109), which is used to fix the upper end of the launch mechanism (4).

[0014] Preferably, the lower receiver (102) is provided with a feed interface slot (110) and a release button (111) at the front, and the feed interface slot (110) and the release button (111) are used for the installation and release of the feed mechanism (5).

[0015] Preferably, the high-pressure gas cylinder (301) is threadedly connected to a pressure reducing device (302).

[0016] Preferably, the sear (403) is hinged to the transmitter base (401), and the trigger (402) is hinged to the receiver component (1). A sear spring (404) is provided between the rear end of the sear (403) and the transmitter base (401). The sear spring (404) is used to lift the rear end of the sear (403), and the rear end of the sear (403) blocks the limiting plate (113). When the limiting plate (113) moves back to its original position, it can press down the sear. At the rear end of the iron (403), past the sear (403), between the front end of the trigger (402) and the firing base (401), there is a trigger spring (405). The trigger spring (405) is used to return the trigger (402) to its original position. The upper rear end of the trigger (402) is provided with a force-applying part. When the trigger (402) is pulled, the force-applying part moves upward, lifting the front end of the trigger (402) and causing the rear end of the trigger (402) to descend, releasing the limiting plate (113).

[0017] By employing the above technical solution, the pneumatic launching device of this invention uses high-pressure gas as a power source and mainly launches spherical projectiles such as capsaicin tear gas grenades, dye-marking grenades, and rubber bullets for non-lethal strikes. This invention has the following beneficial effects:

[0018] The pneumatic launching device has a compact structure, an inexpensive and readily available power source, and features light weight, short length, reliable launch, and the ability to launch a variety of types of ammunition. Attached Figure Description

[0030] Referring to the accompanying drawings, a pneumatic launching device includes a receiver assembly, a launch tube, a high-pressure gas cylinder and a pressure reducing device, a launching mechanism, and a feeding mechanism.

[0031] The pneumatic launching device housing component 1 has a launching tube 2 installed at the front end and a high-pressure gas cylinder and pressure reducing device 3 connected at the rear end. The launching mechanism 4 and the ammunition feeding mechanism 5 are installed inside.

[0032] The receiver component 1 comprises two parts: an upper receiver 101 and a lower receiver 102. The upper receiver 101 has a launch tube connection thread 103 at its front end for threaded connection with the launch tube 2; a push tube 104 and a recoil spring 105 are located in the middle; after the push tube 104 is released, it releases high-pressure gas to propel the projectile; after firing, the recoil spring 105 pushes back the push tube 104 and seals the cylinder 106; the rear part has a cylinder 106 and a gas cylinder connection thread 107, which accommodates high-pressure gas, and the gas cylinder connection thread 107 connects to a high-pressure gas cylinder and a pressure reducing device 3; a standard Picatinny rail interface 108 is located at the top for connecting external aiming devices, etc.; and a firing mechanism interface 109 is located at the bottom for mounting the firing mechanism 4. The lower receiver 102 has a feed interface slot 110 and a release button 111 at its front for mounting and releasing the feed mechanism 5. The feeding mechanism 5 can be installed and disengaged using a conventional magazine connection structure.

[0033] The launching tube 2 is provided with a connecting thread 201, which is connected to the upper receiver 101 to give the projectile an initial velocity and direction.

[0034] The high-pressure gas cylinder and pressure reducing device 3 include a high-pressure gas cylinder 301 and a pressure reducing device 302, which are connected by threads. The high-pressure gas cylinder 301 is used to store high-pressure gas to provide a power source for the launching device. The pressure reducing device 302 is used to reduce the pressure of the high-pressure gas in the high-pressure gas cylinder 301 to the pressure required for launching, and then input it into the cylinder 106 of the casing component 1 for storage and backup.

[0035] The launching mechanism 4 is provided with a launcher base 401 for mounting a trigger 402, a sear 403, a sear spring 404, and a trigger spring 405. The trigger 402 controls the movement of the sear 403, which prevents the projectile tube 104 from moving forward. The sear spring 404 stores energy for resetting the sear 403, and the trigger spring 405 stores energy for resetting the trigger 402. The sear 403 blocks the forward movement of the projectile tube 104 and the limiting plate 113, sealing the high-pressure gas. The trigger 402 releases the sear 403, releasing the high-pressure gas and launching the projectile. The sear spring 404 stores energy for resetting the sear 403, and the trigger spring 405 stores energy for resetting the trigger 402. When the recoil spring 105 overcomes the small air pressure to push the projectile tube 104 and the limiting plate 113 back to their original positions and pass the sear 403, the sear 403, under the action of the sear spring 404, rises back to its original position, blocking the forward movement of the projectile tube 104 and the limiting plate 113. When the trigger 402 is pulled, the sear 403, under the action of the trigger 402, releases the high-pressure gas from the projectile tube 104 and the limiting plate 113, launching the high-pressure gas. After launching the projectile, the trigger 402 is released, and the trigger 402 returns to its original position under the action of the trigger spring 405, preparing for the next launch.

[0036] The feeding mechanism 5 utilizes the energy stored in the support spring 501 to feed the projectile. It is equipped with a projectile support plate 502 to support the projectile upwards and feed it into the receiver component 1. The projectile limiting plate 503 is used to limit the position of the projectile, preventing it from ejecting from the magazine body 504. The control method of the projectile limiting plate 503 is the same as that of existing magazines.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
