Description

A percussion-triggered extended-range anti-riot grenade

technical field

The invention relates to the technical field of anti-riot equipment, and more specifically, relates to an impact-triggered extended-range anti-riot grenade.

Background technique

Rifle grenade is a kind of super-caliber ammunition launched by guns and bullets or empty shells. The muzzle velocity is obtained by the action of gunpowder gas in the gun and the kinetic energy of bullets. It is mainly used to deal with living targets, armored targets and non-armored targets. The rifle grenade is basically similar in structure to the fin-stabilized projectile, the difference is that there is an extra tail pipe device for launching, and a buffer and a bullet collector are installed in the tail pipe. Put the grenade on the barrel before shooting, and the bullet hits the collector when firing, and it acquires a certain initial velocity under the action of gunpowder gas.

Anti-riot grenades are mainly used to temporarily disable groups or individual targets without causing permanent disabilities, and belong to the category of non-lethal ammunition. At present, non-lethal ammunition plays an important role in the tasks of anti-terrorism, emergency response, stability maintenance, and maritime rights protection in the army, armed police, and public security. However, there are generally problems such as short range, low accuracy, and single function. In order to achieve the expected tactical effect, the thrower has to get close to the criminal suspect or the rioting crowd, so that he is exposed to the attack range of the opponent (such as the attack of bricks, stones, glass bottles) . The anti-riot ammunition fired by guns is to avoid bombing accidents, usually incendiary ammunition, which cannot form a greater deterrent to long-distance targets, and explosive non-lethal ammunition with greater deterrence, such as detonation bombs and detonation bombs. However, the throwing distance is greatly shortened, and there are major safety hazards such as explosives. Therefore, these non-lethal ammunition cannot effectively deal with the increasingly complex and changeable anti-terrorism and stability maintenance situations.

Anti-riot grenade is one of the common anti-riot equipment. Compared with anti-personnel ammunition, anti-riot grenade has simple structure and low cost, and is suitable for various emergencies and anti-riot needs.
