Abstract

The invention discloses a safe mechanical trigger fuse for a large-diameter explosive bullet head. The safe mechanical trigger fuse comprises a shell, a shaping ring, a impact type trigger and self-destruction mechanism, a soft belt, an explosion-proof and delayed release safety mechanism, a split ring and a recoil safety mechanism and booster tube. The impact type trigger and self-destruction mechanism comprises a support, a shear pin, a first firing pin and a delay tube assembly, the delay tube assembly comprises an acupuncture delay fire cap, a trigger body and a second firing pin, and impact trigger and self-destruction functions can be achieved. The soft belt is a safety piece of the impact type trigger and self-destruction mechanism. The explosion-proof and delayed release safety mechanism is a ball rotor and has an inertia trigger function. The recoil safety mechanism and booster tube comprises a booster tube and a truncated-cone-shaped supporting cylinder. The fuse is simple in structure, the fuse space is fully utilized, and the fuse has the explosion suppression, redundant safety, delayed release safety, self-destruction and self-failure functions and is also suitable for small-caliber artillery grenades.

Description

technical field [0001] The invention belongs to the large-caliber explosive bullet fuze technology, in particular to a large-caliber explosive bullet warhead mechanical trigger fuze, which is also applicable to small-caliber artillery grenades. Background technique [0002] Large-caliber explosive bullets are of great significance for improving the power of firearms. But explosive charge is housed in the explosive bullet, all is to detonate with simple and easy non-flameproof fuze in the past. Due to the high overload of bullets, generally at 100,000 g Above, so the potential safety hazard of the non-explosion-proof fuze of the bullet is very prominent, and accidents of bore explosion and muzzle explosion occur from time to time. Contents of the invention [0003] The object of the present invention is to provide a safe mechanical trigger fuze for large-caliber explosive bullets, which can comprehensively improve the safety of large-caliber explosive bullets and further ...
