Description
Technical Field
[0001] This utility model relates to the field of anti-explosive ammunition technology, specifically to a 48mm stun grenade for hand-thrown anti-riot use. Background Technology
[0002] Riot control ammunition is a non-lethal security control device that disperses crowds and subdues targets through physical, chemical, or sensory interference while minimizing the risk of permanent injury.
[0003] Riot control grenades are mainly classified into four categories according to their mechanism of action: chemical stimulation type (such as tear gas), kinetic energy impact type (such as rubber bullets, plastic ball bullets, beanbag bullets), sensory suppression type (such as stun grenades, flashbangs), and electric shock subjugation type (such as stun grenades).
[0004] Among them, stun grenades, as a commonly used riot control grenade, can instantly induce panic in targets, thereby reducing their ability to resist. They can be quickly effective in responding to emergencies, and their deterrent effect is greater than their actual lethality, effectively preventing unnecessary casualties. Most existing stun grenades are the 2010 type 38mm police stun grenades (GA / T1306-2016), with a diameter of 38mm, a range of ≥130 meters, a peak sound pressure level of 150~170dB at 5m of detonation, and an instantaneous flash intensity of 1.5×10 cd~3.5×10 cd, suitable for long-range counter-terrorism and riot control operations. However, these stun grenades fired from police guns may not be able to accurately strike rioters or terrorists at close range. Furthermore, due to their small caliber, the explosive charge is small, and in open environments, the sound and flash of rioters or terrorists at a distance from the detonation point are reduced, failing to provide a sufficient deterrent effect. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to provide a 48mm stun grenade for hand-thrown riot control that can emit a louder sound and a brighter light, is suitable for use in a wide space, and can carry out more precise strikes.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A type of hand-thrown 48mm stun grenade for riot control, comprising:
[0008] The ignition mechanism includes a fuse body, a grip, and a needle-delay detonator. The needle-delay detonator is connected to the fuse body via a fixing sleeve. A pin and a cotter pin are movably connected to the fuse body. The grip is fixedly connected to the pin. A spring and a firing pin block assembly are connected to the pin. The firing pin block assembly includes a firing pin and a flipping block. The firing pin block assembly has a first position and a second position. The first position is where the firing pin is separated from the needle-delay detonator, and the second position is where the firing pin abuts against the needle-delay detonator. The position where the needle-piercing delayed detonator strikes is such that the flipping block is connected to the pin, one end of the spring abuts against the flipping block, and in the first position, the spring is compressed under the action of the flipping block, and when the spring returns to its original position, it can drive the firing pin block assembly to rotate from the first position to the second position; the cotter pin has an opening at one end extending from the fuse body, and a connecting part at the other end extending from the fuse body, with a pull ring connected to the connecting part, and when the firing pin block assembly is in the first position, the cotter pin abuts against the firing pin;
[0009] The powder box mechanism is connected to the ignition mechanism. The powder box mechanism includes a shell, an inner powder box, and an end cap. The end cap is fixedly connected to the fuse body. The inner powder box is filled with a detonating agent. The needle-piercing delay detonator extends into the detonating agent. A filling chamber is provided in the shell and filled with paraffin wax.
[0010] The working principle of this utility model is as follows: When using the stun grenade, the thrower holds the ammunition with one hand, pointing the grip towards the web of the thumb, and hooks the pull ring with the index finger of the other hand. Both hands work together to pull out the cotter pin. At this time, due to the action of the grip, the firing pin block assembly will remain in the first position. Then the thrower throws the stun grenade towards the target area. After the stun grenade is released, the compressed spring returns to its original position, causing the flipping block and firing pin to rotate from the first position to the second position around the pin shaft. When the firing pin rotates to the second position, the firing pin will strike the needle-delay detonator. After a set delay, the needle-delay detonator will detonate the stun agent in the cartridge mechanism. The stun agent explodes and emits a loud sound and a bright light, which has a deterrent effect.
[0011] Meanwhile, since this solution fills the filling chamber of the shell with paraffin wax, the paraffin wax is in a solid state in the filling chamber when not in use. When the detonator explodes, the high temperature generated will liquefy the paraffin wax. After the paraffin wax liquefies, it expands due to heat, which can promote the uniform disintegration of the shell and suppress the splashing of fragments. On the other hand, it also greatly reduces the fragments generated after the entire shell breaks, thereby greatly reducing the accidental injury to the human body caused by the fragments generated during the explosion.
[0012] Preferably, the end of the grip piece near the cotter pin extends downward to form a gripping portion, and the end of the grip piece away from the cotter pin extends outward to form a limiting portion. A limiting post is provided on the fuse body. When the firing pin block assembly is in the first position, there is a gap between the limiting portion and the limiting post. When the firing pin block assembly is in the second position, the limiting portion and the limiting post are in abutting position.
[0013] In this way, the extended grip section makes it easy for the thrower to hold the object, and the design of the limiting section and limiting post ensures that the grip can effectively hold the firing pin block assembly in the first position before throwing, thus ensuring safety before throwing.
[0014] Preferably, the fuse body has an external thread at one end near the medicine box mechanism, and the end cap has an internal thread, with the external thread on the fuse body and the internal thread on the end cap being connected.
[0015] In this way, the fuse body and the end cap are fixedly connected by threads, which is a simple and reliable connection method.
[0016] Preferably, the connecting part of the cotter pin has a connecting hole, and the pull ring is sleeved on the connecting hole.
[0017] In this way, the pull ring is fitted onto the connecting hole, allowing the thrower to effectively pull out the cotter pin when pulling the pull ring.
[0018] Preferably, the stun grenade further includes a protective cap, which is fitted onto the firing mechanism and connected to the end cap.
[0019] In this way, by setting up a protective cap, the safety of storing the stun grenade when it is not in use is improved.
[0020] Preferably, the depth to which the needle-piercing delay detonator extends into the detonating agent is 1 / 2 to 2 / 3 of the total depth of the detonating agent.
[0021] In this way, the depth to which the needle-delayed detonator penetrates into the stun agent is 1 / 2 to 2 / 3 of the total depth of the stun agent, which allows the stun needle-delayed detonator to effectively detonate the stun agent, thereby ensuring the effectiveness of the stun grenade.
[0022] Preferably, when the firing pin block assembly is in the second position, the firing pin abuts against the center of the head of the needle-piercing delay detonator to impact the needle-piercing delay detonator.
[0023] In this way, the firing pin abuts against the center of the head of the needle-delay detonator to strike the needle-delay detonator, which ensures that the firing pin effectively strikes the needle-delay detonator, thereby ensuring the effective detonation of the stun grenade.
[0024] Preferably, the outer diameter of the housing is 48 mm.
[0025] Preferably, the shell and the end cap are both made of high-density polyethylene, and the inner medicine box is made of low-density polyethylene.
[0026] Compared with the prior art, the present invention has the following advantages:
[0027] 1. Compared with existing small-caliber gun-type stun grenades, the stun grenade of this design has a diameter of 48mm. Therefore, the stun grenade of this design has a larger explosive charge, which can produce a greater sound and bright light near the blast point, making it more suitable for use in a wide space.
[0028] 2. Compared with the gun-fired stun grenades of the existing technology, the stun grenades of this solution are hand-thrown by the thrower. After professional training, the landing accuracy of hand-thrown stun grenades is higher than that of gun-fired stun grenades, which can accurately hit close-range targets and prevent accidental injury to others.
[0029] 3. The outer shell of this design is made of plastic, which makes the overall weight of the stun grenade lighter and easier to carry; and the fragments after the explosion will not cause fatal injuries to people. Attached Figure Description

[0039] Stun grenades, a commonly used riot control grenade, can instantly induce panic in targets, thereby reducing their ability to resist. They are highly effective in responding to emergencies, with a deterrent effect greater than their actual lethality, effectively preventing unnecessary casualties. Most existing stun grenades are the 2010 type 38mm police stun grenades (GA / T1306-2016), with a diameter of 38mm, a range of ≥130 meters, a peak sound pressure level of 150~170dB at 5m of detonation, and an instantaneous flash intensity of 1.5×10⁻⁶ cd~3.5×10⁻⁶ cd, suitable for long-range counter-terrorism and riot control operations. However, these stun grenades fired from police guns may not be accurate enough for close-range contact with rioters or terrorists. Furthermore, due to their small caliber, the explosive charge is small, and in open environments, the sound and flash of the rioters or terrorists at a distance from the detonation point are reduced, failing to provide a sufficient deterrent effect.
[0040] To address the aforementioned issues, this specific embodiment provides a 48mm stun grenade for hand-thrown riot control, as shown in the attached document. Figure 1 As shown, it includes an ignition mechanism 1 and a powder box mechanism 2, wherein, as attached... Figure 2 To the attached Figure 4As shown, the ignition mechanism 1 includes a fuse body 101, a gripper 110, and a needle-punched delay detonator 109. The fuse body 101 is made of high-density polyethylene (HDPE), with a density range of 0.941 - 0.967 g / cm³. The needle-punched delay detonator 109 is connected to the fuse body 101 via a fixing sleeve 108. In this specific embodiment, the delay time of the needle-punched delay detonator 109 is 3-4 seconds. The fixing sleeve 108 is also made of HDPE, and the fuse body 101 and the fixing sleeve 108 are connected by a threaded connection. A pin 102 and a cotter pin 106 are also movably connected to the fuse body 101. The pin 102 is rotatably connected to the fuse body 101. The hole on the fuse body 101 where the cotter pin 106 is installed is slightly larger than the outer diameter of the cotter pin 106, allowing the pull ring 107 to easily pull out the cotter pin 106. The grip 110 is fixedly connected to the pin 102, which allows the grip 110 to fix the pin 102 before the stun grenade is thrown, thereby keeping the firing pin block assembly in the first position. A spring 103 and a firing pin block assembly are also connected to the pin 102. The firing pin block assembly includes a firing pin 105 and a flipping block 104. The firing pin block assembly has a first position and a second position. The first position is the position where the firing pin 105 is separated from the needle-piercing delay detonator 109. The second position is the position where the firing pin 105 abuts against the needle-piercing delay detonator 109 to strike the needle-piercing delay detonator 109. The flipping block 104 is connected to the pin 102. One end of the spring 103 abuts against the flipping block 104. In the first position, the spring 103 is in a compressed state under the action of the flipping block 104. When the spring 103 returns to its original position, it can drive the firing pin block assembly to rotate from the first position to the second position. The cotter pin 106 has an opening at one end of the fuse body 101 and a connecting part at the other end of the cotter pin 106. A pull ring 107 is connected to the connecting part. When the firing pin block assembly is in the first position, the cotter pin 106 abuts against the firing pin 105.
[0041] In this specific embodiment, the end of the grip 110 near the cotter pin 106 extends downward to form a grip portion, and the end of the grip 110 away from the cotter pin 106 extends outward to form a limiting portion. A limiting post 1011 is provided on the fuse body 101. When the firing pin assembly is in the first position, there is a gap between the limiting portion and the limiting post 1011. When the firing pin assembly is in the second position, the limiting portion and the limiting post 1011 are in abutment position. In this way, the extended grip portion facilitates the thrower's grip, and the design of the limiting portion and the limiting post 1011 ensures that the grip 110 can effectively hold the firing pin assembly in the first position before throwing, thus ensuring safety before throwing.
[0042] In this specific embodiment, a connecting hole is provided on the connecting part of the cotter pin 106, and a pull ring 107 is sleeved on the connecting hole. In this way, the pull ring 107 sleeved on the connecting hole allows the thrower to effectively pull out the cotter pin 106 when pulling the pull ring 107.
[0043] In this specific embodiment, when the firing pin block assembly is in the second position, the firing pin 105 abuts against the center of the head of the needle-delay detonator 109 to impact the needle-delay detonator 109. This abutment between the firing pin 105 and the center of the head of the needle-delay detonator 109 ensures an effective impact, thereby guaranteeing the effective detonation of the stun grenade.
[0044] In this specific embodiment, the medicine box mechanism 2 is connected to the ignition mechanism 1, as shown in the attached figure. Figure 5 As shown, the medicine box mechanism 2 includes a shell 204, an inner medicine box 203, and an end cap 201. The outer diameter of the shell 204 is 48 mm. Both the shell 204 and the end cap 201 are made of high-density polyethylene, while the inner medicine box 203 is made of low-density polyethylene. The density range of the low-density polyethylene material in this design is 0.910 - 0.940 g / cm³. The end cap 201 is fixedly connected to the fuse body 101. Specifically, the end of the fuse body 101 near the medicine box mechanism 2 has an external thread, and the end cap 201 has an internal thread. The external thread on the fuse body 101 and the internal thread on the end cap 201 are connected. In this way, the fuse body 101 and the end cap 201 are fixedly connected by threads, which is a simple and reliable connection method. The inner cartridge 203 is filled with stun agent 202. A needle-delayed detonator 109 extends into the stun agent 202 to a depth of 1 / 2 to 2 / 3 of the total depth of the stun agent 202. This ensures that the needle-delayed detonator 109 effectively detonates the stun agent 202, thereby guaranteeing the effectiveness of the stun grenade. A filling chamber (not shown) is formed inside the casing 204, and the filling chamber is filled with paraffin wax.
[0045] In this specific embodiment, the stun grenade also includes a protective cap (not shown), which is fitted onto the firing mechanism 1 and connected to the end cap 201. By providing the protective cap, the safety of the stun grenade when not in use is improved.
[0046] The working principle of this utility model is as follows: When using the stun grenade, the thrower holds the ammunition with one hand, with the grip plate 110 facing the web of the thumb, and hooks the pull ring 107 with the index finger of the other hand. The thrower pulls out the cotter pin 106 with both hands. At this time, due to the action of the grip plate 110, the firing pin block assembly will remain in the first position. Then the thrower throws the stun grenade towards the target area. After the stun grenade is thrown, the compressed spring 103 returns to its original position, causing the flipping block 104 and the firing pin 105 to rotate from the first position to the second position around the pin 102. When the firing pin 105 rotates to the second position, the firing pin 105 will strike the needle-delay detonator 109. After a set delay, the needle-delay detonator 109 will detonate the stun agent 202 in the cartridge mechanism 2. The stun agent 202 explodes and emits a loud sound and a bright light, which has a deterrent effect.
[0047] Meanwhile, since this solution fills the filling chamber of the shell 204 with paraffin wax, when not in use, the paraffin wax is in a solid state in the filling chamber. When the detonator 202 explodes, the high temperature generated will liquefy the paraffin wax. After the paraffin wax liquefies, on the one hand, the thermal expansion can promote the uniform disintegration of the shell 204 and suppress the splashing of fragments. On the other hand, it also greatly reduces the fragments generated after the entire shell 204 is broken, thereby greatly reducing the accidental injury to the human body caused by the fragments generated during the explosion.
[0048] Compared to existing small-caliber gun-fired stun grenades, this design features a 48mm diameter stun grenade, allowing for a larger explosive charge. This results in a louder sound and brighter flash near the detonation point, making it more suitable for use in open spaces. Furthermore, unlike existing gun-fired stun grenades, this design utilizes a hand-throwing method. With professional training, hand-thrown stun grenades exhibit higher accuracy, precisely targeting close-range objects and preventing accidental injury. Additionally, the outer shell is made entirely of plastic, making the stun grenade lightweight and easy to carry; and the fragmentation after detonation will not cause fatal injuries.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
