Description

Slider type safety arming device {SAFETY ARMING DEVICE}

The present invention relates to a slider-type safety loading device, and more specifically, to a slider-type safety loading device that can load bullets without using rotational force or backward inertial force.

In general, fuses coupled to ammunition such as aerial explosives are equipped with a safety loading device to prevent the gun from being loaded within a preset time before or after launch.

The safety loading device prevents ammunition from being loaded before and after a certain period of time has elapsed, preventing safety accidents such as explosions during handling or at close range after firing.

Existing safety loading devices have a safety structure that restrains the rotor using a release key or inertia pin.

That is, in the conventional safety loading device, the release lock is released by the centrifugal force generated by the rotational force generated when firing the bullet, or the inertia pin is released by the backward inertial force, so that the rotor rotates and the rotor's gear is attached to the gear assembly. This causes reload delay time.

However, the conventional safety loading device has the disadvantage of not being applicable to bullets that do not generate rotational force or backward inertial force.

In addition, the conventional safety loading device has a problem in that it cannot be particularly applied to penetration fuzes because, when the rotation or backward inertia of the bullet is weak, the weight of the rotor or inertial weight must be increased, making it vulnerable to high impacts of 15,000 G or more.

The linear movement plate 316 is movably positioned within the plate mounting space 120 located in the main body housing portion 100, and the plate linear movement guide 340 moves linearly on the inner surface of the plate mounting space 120. A slit groove portion 341 for movement guidance located in the moving direction of the plate 316 and a slit groove portion 341 for movement guidance are positioned to protrude from one side of the linear movement plate 316 and are inserted into the slit groove portion 341 for movement guidance. ) includes a side protrusion 342 that moves along.

The side protrusion 342 is inserted into the movement guide slit groove portion 341 and guides the linear movement of the linear movement plate 316 while moving linearly along the movement guide slit groove portion 341.

In addition, the plate linear movement guide portion 340 includes a linear movement guide protrusion 343 that protrudes from one surface located in the linear movement direction of the linear movement plate 316, and is located within the plate mounting space 120 and is used for linear movement guidance. The protrusion 343 further includes an insertion portion 344 for guiding linear movement that is movably inserted into the interior.

The linear movement guiding protrusion 343 is inserted into the linear movement guiding insertion portion 344 and guides the linear movement of the linear movement plate 316 while moving linearly within the linear movement guiding insertion portion 344.

In addition, the plate linear movement guide 340 is positioned to surround the outer periphery of the linear movement guide protrusion 343, and the linear movement plate 316 is moved to release the restraint of the loading slider 200. When positioned, the linear movement guide insertion portion 344 is combined with an interference fit inside to further include an interference fitting fixing part 345 that fixes the position of the linear movement plate 316.

In addition, the straight-line movement guide insertion part 344 has an inclined surface on the end side whose cross-sectional area becomes smaller toward the end, so that it can be smoothly inserted into the interference fitting fixing part 345 and press-fitted.

The linear movement plate 316 is elastically supported by the spring member 330 for supporting the locking position and is located in the locking groove 200c for locking, and constrains the position of the loading slider portion 200.

Then, when the bullet is fired and the linear movement space 110, that is, the pin movement space 112, which was blocked by the launch port or gun port is opened, and the piston actuator 320 is activated after a preset time, the piston rod moves the linear movement space 112. As the moving plate 316 is pushed and moved, the restraint on the loading slider unit 200 is released.

The linear movement plate 316 moves the piston rod as the side protrusion 342 moves within the slit groove portion 341 for guidance of movement, and the protrusion 343 for guidance of linear movement moves within the insertion portion 344 for guidance of linear movement. It is pushed by and moves smoothly in a straight line to release the restraint of the loading slider unit 200.

The position of the linear movement plate 316 is fixed as the linear movement guide insertion part 344 is pressed into the interference fitting fixing part 345 at the position where the loading slider part 200 is released, thereby preventing malfunction. This can be prevented, and the restraint of the loading slider unit 200 can be stably released.

The present invention allows the safety element to be finally released by receiving an electrical signal without using external force conditions such as centrifugal force due to the rotational force of the bullet and backward inertial force due to acceleration of the bullet, so it can be applied to various types of bullets, greatly increasing its usability. It can be improved.

In addition, the present invention can prevent misloading that occurs when rotational force and reverse inertial force are insufficient, and has the effect of greatly improving operational stability.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented with various changes without departing from the gist of the present invention, and these are included in the configuration of the present invention.
