Inclined recoil safety mechanism for fuse

Abstract

The invention discloses an inclined recoil safety mechanism for a fuse. The inclined recoil safety mechanism for the fuse comprises an inertia body, a protected part, a body and an inertia spring. Two crossed and communicated channels are arranged in the body. The inertia body and the protected part are arranged in the two channels respectively. The inertia spring and the inertia body are coaxially arranged in the channels of the body, and the two ends of the inertia spring and the two ends of the inertia body are limited by the inner end face of the inertia body and the inner end face of the body respectively. The two ends of the inertia body are limited by the inner wall of the body and the inertia spring. The inertia body has a state of limiting the protected part and a state of not limiting the protected part on the movement track of the inertia body. The movement track of the inertia body is arranged in an angle alpha relative to the axis of the fuse, wherein alpha is smaller than or equal to (90-arctanu) degrees , and u is the friction coefficient between the outer wall of the inertia body and the channels of the body. According to the inclined recoil safety mechanism for the fuse, the conflict between safety of the recoil safety mechanism for the fuse and reliable safety releasing under the low recoil overload condition can be removed, various complex environments where the recoil safety mechanism for the fuse acts can be met, the structure is simple, and production cost is low.

Description

technical field [0001] The invention belongs to the technical field of fuze safety, in particular to an oblique recoil insurance mechanism for a fuze. Background technique [0002] At present, the trajectory of the inertial body of the commonly used fuze classical recoil safety mechanism is parallel or coincident with the axis of the fuze, and its structure is relatively simple, easy to use, and good in manufacturability. However, the contradiction between safety and reliable disengagement of the fuze recoil insurance mechanism is still very prominent under the low recoil overload condition, and abnormal disarming phenomenon still exists when the service handling projectile and the fuze accidentally drop. [0003] In order to solve this problem, various damping type recoil safety mechanisms have been born, such as zigzag groove recoil safety mechanisms and dual-degree-of-freedom recoil safety mechanisms. Although the introduction of the damped recoil safety mechanism can so...

AI Technical Summary

Problems solved by technology

Although the introduction of the damped recoil safety mechanism can solve the contradiction between the safety of the fuze recoil safety mechanism and the reliable disarming under the condition of low recoil overload to a certain extent, the structure will become complicated compared with the fuze classic recoil safety mechanism

The introduction of complex structures will affect the reliability and manufacturability of the mechanism, and will increase the production cost
