Hand grenade fuse with switchable delay time

Abstract

The invention discloses a hand grenade fuze with switchable delay time. The hand grenade fuze with the switchable delay time comprises a fuze base body and a safety handle rotationally connected to the fuze base body, and the fuze base body is provided with a percussion ignition mechanism, a redundant insurance mechanism and a delay switching mechanism; the delay time of the hand grenade fuze is selected through the delay switching mechanism, and the redundant insurance mechanism and the delay switching mechanism are ignited through the percussion ignition mechanism; and the redundant insurance mechanism comprises an explosion-proof assembly, a hand-out insurance assembly and a delay insurance assembly, the explosion-proof assembly isolates the delay switching mechanism and a main charge in a hand grenade, and the explosion-proof assembly performs redundant insurance through the hand-out insurance assembly and the delay insurance assembly. The hand grenade fuze is simple in structure, reasonable in design, convenient to implement, can be effectively applied to the hand grenade, can well match the overall function of the hand grenade, greatly improves the safety and tactical flexibility of the hand grenade, and is good in use effect and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of hand grenades, and in particular relates to a hand grenade fuze with switchable delay time. Background technique [0002] As a throwing ammunition weapon carried by an individual soldier, the grenade is different from conventional ammunition weapons. It has no launch environment force and ballistic environment force to use. The combat environment of soldiers is complex, and the fuze insurance can only be released by the operation of soldiers. Therefore, the fuze must ensure the safety of service and use, and at the same time, the convenience of operation and the flexibility of tactics when soldiers use it should be taken into account. The traditional hand grenade fuze uses a propellant delay tube to delay ignition, but because the reliability rate of the propellant delay tube cannot reach 100%, the grenade will have early detonation and instantaneous detonation accidents during troop training and use, whi...

AI Technical Summary

Problems solved by technology

The traditional hand grenade fuze uses the gunpowder delay tube to delay ignition, but because the reliability rate of the gunpowder delay tube cannot reach 100%, it will cause early explosion and instantaneous explosion accidents during the training and use of the grenade, which cannot ensure the safety of the troops when throwing it.

[0003] In addition, the grenade fuze in the prior art adopts a single fixed delay mode. In actual use, the operational flexibility is poor for targets at different distances.

Especially for hand-throwing anti-riot bombs, when used at close range, the target has a long reaction time, and it is easy to be picked up by the target and thrown back, causing damage to our personnel
