Description

Technical Field

[0001] This invention relates to the field of non-lethal ammunition technology, specifically a delayed-explosion kinetic energy tear gas grenade. Background Technology

[0002] Traditional non-lethal kinetic energy munitions are mainly rubber bullets and beanbag rounds, which have problems of "excessive power at close range and insufficient effectiveness at long range" to varying degrees. In order to further improve the safety and effectiveness of non-lethal kinetic energy munitions, it is necessary to continuously improve their intelligence level.

[0003] By igniting a high-pressure gas cylinder to instantly release compressed gas, non-lethal agents can be sprayed. Since no sparks are produced, it can be used in places such as oil depots and haystacks, and can also be used directly to shoot people without causing burns. At the same time, spray speed limiting and energy slow release can be used to improve safety. Summary of the Invention

[0004] The purpose of this invention is to provide a delayed-explosion kinetic energy tear gas grenade to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a delayed-detonation kinetic energy tear gas grenade, comprising a warhead assembly, a projectile body assembly, and a launching assembly, characterized in that:

[0006] The projectile assembly includes a projectile body, a firing pin, and an insert head. The projectile body has a front hemispherical and rear cylindrical structure. The projectile body is formed by vacuum coating of soft foam material. A firing pin limiting groove is opened at the axial center of the bottom end face of the projectile body. The firing pin is set in the firing pin limiting groove. The firing pin is made of high-hardness tungsten steel material. The firing pin includes a firing pin head, a firing pin rod, and a firing pin tip. The firing pin head is clamped in the firing pin limiting groove. The contact surface between the firing pin head and the firing pin limiting groove is fixed with 814 adhesive. An insert head is provided extending downward from the lower part of the projectile body. The insert head includes a projectile concave ring, a projectile retaining ring, and a projectile outer support ring. An inner support ring is provided on the bottom end face of the projectile body and the outer edge of the firing pin limiting groove. The cross-sections of the projectile concave ring, the projectile retaining ring, the outer support ring, and the inner support ring are all square.

[0007] The warhead assembly is nested and connected to the projectile assembly. The projectile assembly includes a projectile body, a connector, OC irritant powder, a high-pressure gas cylinder, a delay ignition tube, and a detonator. The projectile body includes a main projectile body, a projectile wall, a projectile inner cavity, a projectile concave ring, a projectile band, a projectile retaining ring, and a projectile insertion hole. The projectile body is injection molded from nylon material. The lower end face of the main projectile body is covered with a high-temperature resistant coating. A projectile concave ring is formed inward on the outer side of the projectile wall, and a projectile band is formed outward on the outer side of the projectile wall. The cross-section of the projectile concave ring and the projectile band is square. A projectile retaining ring is formed protruding from the inner side of the top of the projectile wall. The cross-section of the projectile retaining ring is semi-circular. A projectile insertion hole is formed on the central axis of the main projectile body. The projectile insertion hole is hollow cylindrical. The connector is embedded and secured in the projectile inner cavity. The connector includes a connector base, a connector sidewall, a connector inner cavity, a pressure relief hole, a gas cylinder retainer, a receiving joint, a lower connector concave ring, an upper connector concave ring, and an outer receiving ring. The connector comprises an inner receiving ring, a connector retaining ring, and a connector insertion hole. The connector is made of lightweight plastic material. The base of the connector is bonded to the inner cavity of the projectile with 814 adhesive. Four pressure relief holes are formed at the lower end of the side wall of the connector, arranged in a circular array along the central axis of the connector. A plug made of high-density rubber material is inserted into each pressure relief hole. The plug includes an insert end and a retainer. The insert end engages with the pressure relief hole, and the retainer abuts against the inner wall of the connector side wall. A high-pressure gas cylinder is embedded in the middle of the inner cavity of the connector. The high-pressure gas cylinder is secured by a cylinder retainer with two symmetrically arranged limiting strips that restrict the position of the high-pressure gas cylinder. The high-pressure gas cylinder contains compressed air, and the storage pressure of the compressed air in the high-pressure gas cylinder is 2.5MPa, the upper end of the sidewall of the connector extends with a disc-shaped receiving joint, the lower concave ring of the connector has a semi-circular cross-section, the projectile retaining ring is inserted into the lower concave ring of the connector, the upper concave ring of the connector and the retaining ring of the connector both have square cross-sections, the cavity formed by the inner cavity of the projectile, the sidewall of the connector and the receiving joint is filled with OC irritant powder, the projectile retaining ring is inserted into the upper concave ring of the connector, the connector retaining ring is inserted into the projectile concave ring, the outer support ring of the projectile is inserted into the outer receiving ring of the connector, the projectile... The contact surfaces between the head retaining ring and the concave ring on the connecting body, between the contact surface between the connecting body retaining ring and the projectile concave ring, and between the contact surfaces between the outer support ring of the projectile and the outer receiving ring of the connecting body are all bonded together with 814 adhesive. After the projectile impacts the target, it is compressed, and the inner support ring of the projectile is forced into the inner receiving ring of the connecting body. A hollow circular hole communicating with the inner cavity of the connecting body is opened on the central axis of the receiving joint. The hollow circular hole has the same inner diameter as the inner cavity of the connecting body. The firing pin rod is located on the central axis of the hollow circular hole. The tip points to the upper sealing cap of the high-pressure gas cylinder. A connector insertion hole is opened at the center of the connector base axis. The connector insertion hole and the projectile insertion hole have the same inner diameter and are interconnected. A delayed ignition tube is fitted into both the projectile insertion hole and the connector insertion hole. The delay time of the delayed ignition tube is 1.5 seconds. A detonator is threaded onto the inner cavity side of the connector insertion hole. The detonator contains a small amount of detonating explosive. When the target distance is relatively far, the tail of the delayed ignition tube ignites after the delay time, igniting the detonator. The detonator ruptures the lower sealed cap of the high-pressure gas cylinder, releasing compressed air. When the target is close, the projectile impacts the target and compresses, causing the firing pin to strike backward. The firing pin tip punctures the upper sealed cap of the high-pressure gas cylinder, releasing compressed air. The compressed air released from the high-pressure gas cylinder first ruptures the plug, then opens the projectile's retaining ring, and finally propels the OC irritant powder out at high speed from the projectile's retaining ring and the concave ring opening of the connecting body.

[0008] The projectile assembly is nested and connected to the launching assembly. The launching assembly includes a projectile casing and a propellant charge. The projectile casing includes a casing wall, a casing bottom edge, a high-pressure chamber, a ignition port, a low-pressure chamber, and a casing retaining ring. The projectile casing is integrally formed from high-strength aluminum alloy. A high-pressure chamber with a cylindrical cavity is provided at the axial center of the bottom end face of the projectile casing. The propellant charge is riveted into the high-pressure chamber. The propellant charge includes a primer and a propellant charge. The primer is a mechanical impact primer, and the propellant charge is smokeless powder. A ignition port with a cylindrical hole is provided at the top of the high-pressure chamber. The ignition port is sealed with a brass film. The upper side of the high-pressure chamber abuts against the lower end face of the main projectile. The cavity formed by the projectile casing wall, the high-pressure chamber, and the main projectile is the low-pressure chamber. A casing retaining ring is provided on the inner side of the top of the projectile casing wall. The casing retaining ring is engaged with a projectile body recessed ring. The contact surfaces of the projectile casing wall and the main projectile are sealed with hot melt adhesive.

[0009] Preferably, the warhead assembly, the projectile body assembly, and the launching assembly are connected in series, and the warhead assembly, the projectile body assembly, and the launching assembly are all axisymmetric structures, with their central axes coinciding.

[0010] Preferably, the OC stimulating powder can reduce the forward velocity of the warhead assembly and the projectile body assembly when sprayed.

[0011] Preferably, the hot melt adhesive of the sealing cartridge case wall and the main body is rapidly melted by the ablation of the high temperature and high pressure propellant gas generated by the combustion of the propellant, and the projectile body is subjected to the thrust of the propellant gas, which forces the cartridge case retaining ring and the projectile body concave ring to quickly separate, thereby realizing the separation of the projectile body assembly and the launching assembly.

[0012] Preferably, at the instant the projectile assembly and the launch assembly separate, the volume of the low-pressure chamber rapidly increases, and the low-pressure chamber and the high-pressure chamber form a high-low pressure structure, which facilitates the generation of a stable thrust on the projectile assembly and the projectile assembly, thereby ensuring that the projectile assembly and the projectile assembly have a consistent exit velocity.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention employs two methods to fire high-pressure gas cylinders: impact from a firing pin and detonation by a detonator. When the target is far away, the delayed ignition tube ignites at its tail after a 1.5-second delay, igniting a small amount of detonating explosive within the detonator. The detonator then ruptures the lower sealing cap of the high-pressure gas cylinder, releasing compressed air. When the target is close, the projectile impacts the target, undergoing significant compression and propelling the firing pin backward. The firing pin tip then shatters the upper sealing cap of the high-pressure gas cylinder, releasing compressed air. This dual-mechanism design of the firing pin and detonator significantly improves the reliability of cylinder firing. By detonating the high-pressure gas cylinder, the OC irritant powder is rapidly dispersed, both slowing down the projectile and reducing the probability of accidental injury to personnel, thus enhancing the safety of this invention.

[0015] 2. When the explosive body of this invention detonates and breaks the gas cylinder, it will emit a certain explosion sound (the tip of the firing pin breaking the high-pressure gas cylinder sealing cap will also make a sound). The high-pressure air is released with energy, and a second explosion sound will be emitted when it breaks the plug. A third explosion sound will be emitted when it breaks open the projectile retaining ring. The high-speed sprayed OC irritant powder can achieve tear gas dispersal. The projectile assembly that continues to move forward after deceleration can achieve kinetic energy strike on a single target, thereby achieving multiple non-lethal effects such as blast deterrence, tear gas dispersal and kinetic energy strike.

[0016] 3. This invention uses a small amount of explosive to detonate a high-pressure gas cylinder or a firing pin to detonate a gas cylinder to achieve the sound of explosion and the scattering of OC stimulating powder. There is no risk of causing a fire. Therefore, it can be used in places such as oil depots and grassy areas. Even if this invention directly impacts the body of a living target, it will not cause ablation to the living target. Therefore, it greatly increases the scope of application of this invention.

[0017] 4. The present invention employs an inner support ring for the projectile, an inner receiving ring for the connector, an outer support ring for the projectile, an outer receiving ring for the connector, and a matching design, which enables the projectile assembly to achieve uniform compression during impact, thereby greatly reducing the probability of tearing the skin of living targets.

[0018] 5. The projectile assembly and projectile body assembly of this invention are fixedly connected by clamping and 814 glue, and the projectile body assembly and launching assembly are fixedly connected by mechanical insertion and heating glue, which makes the connection of this invention firm. When spinning inside the barrel, all components can achieve synchronous spinning, which is beneficial to improving the accuracy of the strike.

[0019] 5. The lower end face of the main projectile of this invention is covered with a high-temperature resistant coating, which can further prevent the ablation of the projectile components by high-temperature and high-pressure propellant gases; the contact surfaces between the projectile retaining ring and the upper concave ring of the connecting body, between the contact surfaces between the connecting body retaining ring and the projectile concave ring, and between the contact surfaces between the outer support ring of the projectile and the outer receiving ring of the connecting body are all bonded with 814 adhesive, which not only improves the reliability of the connection, but also achieves a better sealing effect, so that the compressed air released from the high-pressure gas cylinder can break through the plug and reliably separate the projectile retaining ring;

[0020] 6. This invention employs a high-low pressure firing system and uses smokeless propellant, which can achieve a consistent exit velocity. At the same time, the amount of muzzle smoke is small and will not interfere with the normal tactical actions of the user. This invention does not produce excessive gunpowder residue in the barrel, thus not affecting repeated firing and projectile accuracy, thereby making this invention highly applicable to the battlefield.

The projectile wall 2-1-2 has a projectile concave ring 2-1-4 extending inward from its outer side, and a projectile band 2-1-4 protruding outward from its outer side. 5. The cross-sections of the projectile's concave ring 2-1-4 and the projectile band 2-1-5 are both square. A projectile retaining ring 2-1-6 protrudes from the inner top of the projectile wall 2-1-2. The cross-section of the projectile retaining ring 2-1-6 is semi-circular. A projectile insertion hole 2-1-7 is opened on the central axis of the main projectile 2-1-1. The projectile insertion hole 2-1-7 is hollow cylindrical. The inner cavity 2-1-3 of the projectile is embedded in and holds the connecting body 2-2. The connecting body 2-2 includes a connecting body base 2-2-1, a connecting body side wall 2-2-2, a connecting body inner cavity 2-2-3, a pressure relief hole 2-2-4, a gas cylinder holder 2-2-5, a receiving joint 2-2-6, a lower concave ring 2-2-7, and an upper concave ring 2-2-8. The connector 2-2 consists of an outer receiving ring 2-2-9, an inner receiving ring 2-2-10, a retaining ring 2-2-11, and a connector insertion hole 2-2-12. The connector 2-2 is made of lightweight plastic. The connector base 2-2-1 and the inner cavity 2-1-3 are bonded together using 814 adhesive. Four pressure relief holes 2-2-4 are formed at the lower end of the connector sidewall 2-2-2, arranged in a circular array along the central axis of the connector 2-2. A plug 2-2-4-1, made of high-density rubber, is inserted into each pressure relief hole 2-2-4. The plug 2-2-4-1 is manufactured as follows: it includes an insert end 2-2-4-1-1 and a clamping head 2-2-4-1-2. The insert end 2-2-4-1-1 is inserted into the pressure relief hole 2-2-4, and the clamping head 2-2-4-1-2 abuts against the inner wall of the connecting body sidewall 2-2-2. A high-pressure gas cylinder 2-4 is embedded in the middle of the connecting body inner cavity 2-2-3. The high-pressure gas cylinder 2-4 is secured by a gas cylinder holder 2-2-5. The gas cylinder holder 2-2-5 includes two symmetrically arranged limiting strips, which limit the position of the high-pressure gas cylinder 2-4. The high-pressure gas cylinder 2-4 is filled with compressed air, and the storage pressure of the compressed air in the high-pressure gas cylinder 2-4 is 2.5MPa, the upper end of the connecting body sidewall 2-2-2 is provided with a disc-shaped receiving joint 2-2-6, the lower concave ring 2-2-7 of the connecting body has a semi-circular cross-section, the projectile retaining ring 2-1-6 is inserted into the lower concave ring 2-2-7 of the connecting body, the upper concave ring 2-2-8 and the connecting body retaining ring 2-2-11 of the connecting body both have square cross-sections, the cavity formed by the inner cavity 2-1-3 of the projectile, the connecting body sidewall 2-2-2 and the receiving joint 2-2-6 is filled with OC irritant powder 2-3, the projectile retaining ring 1-3-2 is inserted into the upper concave ring 2-2-8 of the connecting body, the connecting body retaining ring 2-2-11 is inserted into the projectile concave ring 1-3-1, and the outer support ring 1-3-3 of the projectile is inserted into the outer support ring of the connecting body. The contact surfaces of the connecting ring 2-2-9, the projectile retaining ring 1-3-2 and the concave ring 2-2-8 on the connecting body, the connecting body retaining ring 2-2-11 and the projectile concave ring 1-3-1, and the outer support ring 1-3-3 of the projectile and the outer receiving ring 2-2-9 on the connecting body are all bonded with 814 adhesive. After the projectile body 1-1 impacts the target, it is compressed, and the inner support ring 1-1-2 of the projectile is squeezed into the inner receiving ring 2-2-10 of the connecting body. A hollow circular hole 2-2-6-1, communicating with the inner cavity 2-2-3 of the connecting body, is opened on the central axis of the receiving joint 2-2-6. The inner diameter of the hollow circular hole 2-2-6-1 is equal to that of the inner cavity 2-2-3 of the connecting body. The firing pin rod 1-2- Located on the central axis of the hollow circular hole 2-2-6-1, the firing pin tip 1-2-3 points towards the upper sealing cap of the high-pressure gas cylinder 2-4. A connector insertion hole 2-2-12 is opened at the axis of the connector base 2-2-1. The connector insertion hole 2-2-12 and the projectile insertion hole 2-1-7 have the same inner diameter and are interconnected. A delay ignition tube 2-5 is fitted inside the projectile insertion hole 2-1-7 and the connector insertion hole 2-2-12. The delay time of the delay ignition tube 2-5 is 1.5s. A detonator 2-6 is threaded onto the side of the connector insertion hole 2-2-12 facing the inner cavity 2-2-3 of the connector. The detonator 2-6 contains a small amount of detonating explosive. When the target distance is far, the delay ignition tube 2-5 reaches the desired delay time. After a certain period, the tail section ignites, setting off the detonator 2-6. The detonator 2-6 then ruptures the lower sealed cap of the high-pressure gas cylinder 2-4, releasing compressed air. When the target is close, the projectile body 1-1 impacts the target and compresses, causing the firing pin 1-2 to strike backward. The firing pin tip 1-2-3 punctures the upper sealed cap of the high-pressure gas cylinder 2-4, releasing compressed air. The compressed air released from the high-pressure gas cylinder 2-4 first ruptures the plug 2-2-4-1, then opens the projectile retaining ring 2-1-6, and finally causes the OC irritant powder 2-3 to be ejected at high speed from the openings of the projectile retaining ring 2-1-6 and the concave ring 2-2-7 of the connecting body.

[0038] Combination Figure 2 , Figure 10 and Figure 11 The projectile assembly 2 is nested and connected to the launching assembly 3.

The projectile casing 3-1 includes a casing wall 3-1-1, a casing bottom edge 3-1-2, a high-pressure chamber 3-1-3, a ignition port 3-1-4, a low-pressure chamber 3-1-5, and a casing retaining ring 3-1-6. The projectile casing 3-1 is integrally formed from high-strength aluminum alloy. A high-pressure chamber 3-1-3 with a cylindrical cavity is provided at the axial center of the bottom end face of the projectile casing 3-1.

[0039] like Figure 2 As shown, the warhead assembly 1, the projectile body assembly 2, and the launching assembly 3 are connected in series. The warhead assembly 1, the projectile body assembly 2, and the launching assembly 3 are all axisymmetric structures, and their central axes coincide.

[0040] In this embodiment, the OC stimulating powder 2-3 can reduce the forward velocity of the projectile assembly 1 and the projectile body assembly 2 when sprayed.

[0041] In this embodiment, the hot melt adhesive of the sealed cartridge case wall 3-1-1 and the main projectile body 2-1-1 is rapidly melted by the high temperature and high pressure of the propellant gas generated by the combustion of the propellant 3-2-2. The projectile body 2-1 is subjected to the thrust of the propellant gas, which forces the cartridge case retaining ring 3-1-6 and the projectile body concave ring 2-1-4 to quickly separate, thereby realizing the separation of the projectile body assembly 2 and the launching assembly 3.

[0042] In this embodiment, at the instant the projectile assembly 2 and the launching assembly 3 separate, the volume of the low-pressure chamber 3-1-5 rapidly increases. The low-pressure chamber 3-1-5 and the high-pressure chamber 3-1-3 form a high-low pressure structure, which facilitates the generation of a stable thrust on the projectile assembly 1 and the projectile assembly 2, thereby ensuring that the projectile assembly 1 and the projectile assembly 2 have a consistent exit velocity.
