The separation component is used to realize the ejection of the ignition component to avoid the hard firing seat from accidentally injuring a target. The projectile component has a built-in detonation component and a load component. The load component comprises OC stimulation powder, a marking ball and a rubber ball. The detonation component has a built-in two-stage detonation mechanism, which realizes the emission of the marking ball through a primary explosion, and realizes the rupture of the projectile, the lasing of projectile fragments and rubber balls, and the rapid spraying of OC stimulation powder through a secondary explosion. By designing a prefabricated crack groove, the projectile ball wall explodes to form a uniform kinetic energy injury element without sharp edges. With the addition of the rubber ball, a double kinetic energy strike on a group target is realized, and two explosion sounds are emitted successively, which has the multiple non-lethal strike effects of detonation deterrence, dyeing marking, double kinetic energy strike and stimulation and dispersal.

Description

Among them, hand-thrown non-lethal ammunition has the most types and the most complete functions.

[0021] 3. The present invention adopts the traditional flip-plate firing pin firing mechanism, which not only realizes the standardization of parts selection and the consistency of throwing action, reduces the use cost, but also realizes the effective ejection of the steel firing seat by designing a separation component, thereby improving the safety of use; the projectile body component is provided with a projectile body gripping part, which is convenient for the throwing hand to grip reliably, and the projectile body gripping part is parallel to the vertical section of the safety handle, so that after the safety pin is pulled out, the flip-plate firing pin can still be pressed, which is convenient for waiting for the best opportunity and performing efficient throwing;

[0022] 4. In the two-stage detonation mechanism designed by the present invention, the wall thickness of the first-stage detonation chamber is half of that of the second-stage detonation chamber, and the charge density of the first-stage detonation chamber is one-third of that of the second-stage detonation chamber, so that the second blasting sound is stronger, the detonation deterrent effect is better, and at the same time, the rupture of the projectile, the lasing of the rubber ball and the spraying of the charge can be reliably achieved, and the tactical flexibility is higher;

[0023] 5. In the present invention, hot melt adhesive is used to seal the contact surfaces between the separation component and the projectile component, the second-stage delay tube and the center hole, the projectile plug hole, the first-stage detonation cavity upper plug hole and the second-stage detonation cavity upper plug hole; in the present invention, the second-stage detonation cavity is clamped in the projectile component, and the marking ball is clamped in the blasting impact cavity, so that the present invention has high stability and reliability in storage and transportation, and further improves the service performance of the present invention;

[0024] 6. In the present invention, there are a large number of rubber balls, and the projectile assembly realizes block design through prefabricated crack grooves in the isolation layer and the projectile wall. No fragments with sharp corners are generated after the explosion, and the safety of use is further improved. The kinetic energy impact of the coupling marker ball and rubber ball and the kinetic energy impact of the projectile fragments on the target can achieve multiple kinetic energy strike effects. In addition, the secondary detonation stimulates the rapid spraying of OC powder, making the present invention an excellent non-lethal ammunition for surface dispersal.
