A percussion-type double-safety post-launch delayed firing device

Abstract

The invention discloses a firing-type delayed firing device, which mainly comprises a firing pin, an electric pin puller, a smoothbore pin component, a firing pin spring, a state switch, a flexible delayed detonating cord of a needle-punched detonator, and the like. The electric pin puller and the smoothbore pin have two fuses, which usually lock the firing pin to prevent it from malfunctioning. When launching, external power is supplied to the electric pin puller, and the electric pin puller moves to release the first restraint on the firing pin; Then the percussion-type delayed firing device is pushed out by the propellant in the firing device, and the smoothbore pin part loses the constraint of the barrel wall of the firing device after it exits the gun chamber, releasing the second constraint on the firing pin. The firing pin acts under the thrust of both the state switch and the firing pin spring, the state switch associated with it is switched, and the needle-piercing detonator is fired at the same time, and the flexible delayed detonating cord is detonated. The present invention operates only after leaving the launching device, has high safety, and has the advantages of a state detection function and the like.

Description

technical field [0001] The invention belongs to the technical field of firing mechanisms, and in particular relates to a firing type double-safety delayed firing device after firing, which can only function after leaving the firing device, has high safety, and has the advantages of a state detection function and the like. Background technique [0002] At present, in order to ensure safety, warheads based on artillery fire are generally designed to use the overload in the chamber to release the insurance. After hitting the target, use the impact overload generated by the impact to design an inertial closure or a touch switch to detonate the warhead. [0003] However, there are many kinds of warheads. In order to achieve better damage effect, some warheads require air-explosion above a suitable target after launching. For this requirement, it is obvious that the existing technology cannot be realized, and there is a disadvantage of using the overload release in the chamber to ...

Problems solved by technology

For this requirement, it is obvious that the existing technology cannot be realized, and a defect of using the overload in the bore to release the safety is that once the bullet falls from the barrel, the safety will be misunderstood to a large extent.
