Detonator security mechanism with self-locking function and detonator

Abstract

The invention provides a detonator security mechanism with a self-locking function. The detonator security mechanism comprises a sleeve, a plurality of tiles, a mass rod, detonating powder, a tube shell and a safety mechanism, wherein a step is arranged on the middle part of the mass rod; the sleeve is arranged on the part above the step of the mass rod; the tiles are uniformly distributed on the circumference in the sleeve; the safety mechanism is mounted at the upper end of the mass rod; the detonating powder is connected with the lower end of the mass rod; the tube shell is arranged outside the detonating powder. In a working process, the insurance of the safety mechanism is relieved, and when the mass rod senses overload, the mass rod downward moves to a limited position together with the detonating powder and the tube shell connected with the mass rod, and meanwhile, the tiles lose support and downward fall till reacquiring support from the middle step of the mass rod, so that the mass rod is locked on the limited position. The invention also provides a detonator based on the detonator security mechanism. The detonator security mechanism provided by the invention utilizes flight overload to drive the security mechanism and requires no detonator or flipping power supply for driving, has the self-locking function and high reliability, and is compact in structure and fit for a detonator use occasion with small radial size requirement.

Description

technical field [0001] The invention belongs to the technical field of fuze security, and in particular relates to a fuze security mechanism with a self-locking function and a fuze. Background technique [0002] In the field of fuze technology, the most common motion mechanisms are slider mechanism and isolated rotor mechanism. These two motion mechanisms are usually combined with gunpowder pusher, gunpowder pin puller, motor, electromagnetic pin puller and other insurance components to form a fuze security mechanism. [0003] Existing security agencies have the following deficiencies: [0004] First of all, the radial size of the mechanism is large, which is not suitable for occasions where the radial size is required to be small. [0005] Secondly, the mechanism does not have a locking function after it moves into place. In a vibrating environment, it is easy to cause misalignment of the security mechanism, which eventually leads to incomplete detonation of the fuze. [...

AI Technical Summary

Problems solved by technology

[0004] First of all, the radial size of the mechanism is large, which is not suitable for occasions where the radial size is required to be small

[0005] Secondly, the mechanism does not have a locking function after it is in place. In a vibration environment, it is easy to cause misalignment of the security mechanism, which eventually leads to incomplete detonation of the fuze.

[0006] Again, the above-mentioned security mechanism did not effectively use the environmental information on the bomb (such as flight overload, centrifugal force, aerodynamic heat, etc.), and the driving of insurance parts such as gunpowder pusher, gunpowder pin puller, motor, and electromagnetic pin puller needs to consume fuzes or bombs.
