The safety mechanism of the pin pusher used by the existing domestic fuze safety system is composed of a pin pusher shell, a safety pin sleeve, a shearing pin and a 19# electric igniter tube, wherein the function of the safety mechanism of the pin pusher is mainly realized by the action of the 19# electric igniter tube and locking of the safety pin and the safety pin sleeve after the shearing of the shearing pin, but the safety mechanism of the pin pusher has the following defects that the processing precision requirement of parts in the ① safety mechanism is high, the structure is complex, the structural sizes of parts such as the safety pin, the safety pin sleeve, the pin pusher shell, the shearing pin and the like are small, the related sizes among the parts are large, the safety pin and the safety pin sleeve are locked through a taper angle, the processing precision is high, the processing period is long, the action reliability of the ② action is low, the pin pusher is a gas product generated after the 19# electric igniter tube is detonated, and the safety pin is indirectly pushed to move to cut off the pin through.
Disclosure of Invention
The invention aims to solve the defects of the prior art, and provides an electric pin pusher safety mechanism which can be universally used for a fuse safety system, so that the fuse ensures the service processing safety, has less parts, is easy to machine in structure and high in action reliability, and realizes the optimal combat efficiency.
The technical scheme of the invention is that the safety mechanism of the electric pin pusher comprises a safety body, an explosion-proof piece, a safety reed, a cylindrical head screw, a pin pusher shell, the electric pin pusher and a pressing screw. The safety reed is arranged in an installation groove of the safety body, the installation groove is positioned at the bottom of a pin ejector installation hole on the safety body, the direction of the installation groove is vertical to the axis of the pin ejector installation hole, one end of the safety reed is fixed on the safety body through a cylindrical head screw, the other end of the safety reed props against the side face of the explosion-proof piece, a pin ejector shell is arranged in the pin ejector installation hole of the safety body, and the bottom end face of the pin ejector shell is pressed on the upper surface of the; the electric push pin device is arranged in the push pin device shell, the pressing screw is screwed on the safety body through threads, the electric push pin device is plugged in the push pin device shell through the pressing screw, and two conducting wires of the electric push pin device are led out from a central hole of the pressing screw.
The material of the safety reed (1) is beryllium bronze with the thickness of 0.3mm, and the safety reed is tempered.
Compared with the existing safety mechanism of the pin pushing device, the pin pushing device has the advantages that 1) the structure is reasonable, and the action reliability is good; 2) the invention has the characteristics of few types of parts to be processed, simple structure, easy processing and the like; 3) the invention adopts the electric pushing pin device to directly act on the safety reed, the generated thrust is large, and the action reliability is high.

Detailed Description
As shown in figure 1, the safety mechanism of the electric pin pushing device comprises a safety body 6, an explosion-proof piece 7, a safety reed 1, a cylindrical head screw 2, a pin pushing shell 3, an electric pin pushing device 4 and a pressing screw 5. The position of the explosion-proof member 7 in the fuse body 6 and the position of the fuse body 6 in the fuze are consistent with those of the prior art and are not changed.
The safety reed 1 is installed in the installation groove of the safety body 6, the installation groove is located at the bottom of the pin pushing device installation hole in the safety body 6, and the installation groove is perpendicular to the axis of the pin pushing device installation hole. One end of a safety reed 1 is fixed on the safety body 6 by a cylindrical head screw 2, and the other end of the safety reed 1 props against the side surface of the explosion-proof piece 7 or is inserted into the explosion-proof piece 7; the shell 3 of the push pin is arranged in the mounting hole of the push pin of the safety body, and the bottom end surface of the shell 3 of the push pin is pressed on the upper surface of the middle part of the safety reed 1; the electric push pin device 4 is arranged in the push pin device shell 3, the pressing screw 5 is screwed on the safety body 6 through threads, the electric push pin device 4 is blocked in the push pin device shell 3, two leads of the electric push pin device 4 are led out from a central hole of the pressing screw 5, and two leads of the electric push pin device 4 are connected with a fuse initiation circuit. When in use, the safety fuse is arranged on a safety fuse system of an ammunition primer.
The material of the safety reed 1 is beryllium bronze with 0.3mm, and the part has elasticity after tempering treatment.
The working principle of the invention is as follows: before the fuse sends out a guarantee release signal, the safety reed 1 blocks the movement of the explosion-proof piece to play a role of safety; after the fuse sends a release signal, the electric pin pusher in the safety mechanism of the pin pusher is detonated, the pin on the electric pin pusher penetrates through the central hole of the shell of the pin pusher to press and deform the safety reed, so that the safety reed gives way, the constraint of the safety reed on the explosion-proof piece is relieved, and the explosion-proof piece moves to a position for relieving the safety, thereby achieving the purpose of relieving the safety.
