Description

Safety loading device using a worm gear {SAFETY ARMING DEVICE USING WORM GEAR}

The present invention relates to a safety loading device using a worm gear.

In general, a fuse coupled to ammunition, such as an aerial bomb, is provided with a safety loading device for preventing it from being loaded within a preset time before or after firing.

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

The existing safety loading device is a mechanism that is loaded by moving a slider or rotating a rotor by a separate external force such as an inertia force or a spring, and includes a separate position fixing device to maintain a safe or loaded state.

This is because the state of safety or loading may be changed by an external force such as an external shock.

In addition, in order to secure a safe distance, the safety loading device including the explosive series includes a separate delay device.

Disadvantages of the conventional safety loading device are that it requires a separate fixing device and a delay device to maintain the state after loading the explosive series, so that the structure is complicated and the manufacturing cost is high.

In addition, the conventional safety loading device is additionally in a high shock-resistance environment, the slider or rotor in the loaded state returns to the existing safety loading device, and the loading state is released to a safe state, which implies the possibility that the explosive series operation performance cannot be implemented. There is a downside to doing it.

The position of the gear stopper part 443 in the longitudinal direction of the first side support part 441 or the second side support part 442 is adjusted to adjust the movement distance of the rack gear member 410, thereby rotating the pinion gear member 420. The total amount can be adjusted, thereby adjusting the amount of rotation of the worm gear member 100 and the worm wheel member 200 to adjust the loading position of the first chemical product unit 221 or the second chemical product unit 222 .

The stopper moving support part 444 controls the movement distance of the rack gear member 410 to finally control the amount of rotation of the worm gear member 100 , so that the first chemical part 221 or the second chemical part positioned on the worm wheel member 200 . The chemical part 222 may be selectively positioned in the loading position.

On the other hand, the rotating unit 400 includes a ball support spring 470 for elastically supporting the second ball body 460 and a spring pressing member 480 for pressing the ball support spring 470, which is generated when the bullet is fired. The loading time can be adjusted by adjusting the linear movement speed of the rack gear member 410 that is linearly moved by the inertial force.

As an example, the spring pressing member 480 is a spring support bolt screwed to the second side support 442 .

The spring support bolt moves toward the second ball body 460 while being rotated in a direction to be fastened to the second side support 442 and presses the ball support spring 470 to slow the movement speed of the rack gear member 410 to increase the loading speed. can be delayed

In addition, the spring support bolt is rotated in a direction to be released by the second side support part 442 and moved to the opposite side to the second ball body 460 while lowering the pressing force applied to the ball support spring 470 of the rack gear member 410 . You can increase the movement speed to increase the reload speed.

That is, in the safety loading device using the worm gear according to the present invention, the loading time can be freely adjusted by fastening or loosening the spring support bolt.

On the other hand, another embodiment of the safety loading device using a worm gear according to the present invention is located in the gear stopper part 443, and a contact sensor unit ( 500), the electromagnet unit 600 which is located in the gear stopper unit 443 to seat the rack gear member 410 on the gear stopper unit 443 by magnetic force, and the contact sensor unit 500 receives a signal sensed and an electromagnet control unit 700 for controlling the operation of the electromagnet unit 600 .

The rack gear member 410 may be made of a magnetic material that can be magnetically attached to the electromagnet unit 600, and the weight 411 located at the lower end can be made of a magnetic material that can be attached to it by magnetic force. , by placing a separate magnetic material on the lower end side to reveal that it can be magnetically attached to the electromagnet unit 600 .

The electromagnet control unit 700 includes a timer, and if a detection signal is not transmitted from the contact sensor unit 500 until a preset time, that is, a preset reloading time, it is determined as unloaded.

Then, by operating the electromagnet unit 600, the rack gear member 410 is moved by magnetic force to be magnetically attached to the gear stopper unit 443, so that the chemical product 220 can be forcibly positioned in a loaded state.

That is, the operation of the rack gear member 410 moved by the inertial force after firing is not smooth, so that the chemical product 220 is unloaded, which may cause a misfire.

The electromagnet control unit 700 checks the loading state of the chemical product 220 at a preset loading time through the contact sensor unit 500 , and the rack gear member 410 is not seated on the gear stopper unit 443 in an unloaded state. By operating the electromagnet unit 600 to load the chemical product 220, it prevents an accidental accident, and greatly improves the operational reliability of the bullet.

Alternatively, it is possible to prevent a large accident due to an unexploded bomb in the future.

The present invention can maintain a safe state and a loaded state because it cannot be rotated by an arbitrary external force through a worm gear and a worm wheel, and a loading delay function can be implemented using the reduction ratio of the worm wheel. By eliminating the device, the structure can be simplified, manufacturing costs can be reduced, and performance against high impact can be improved by maintaining a stable state of safety or loading.

The present invention can align a plurality of chemical products 220 to the loading position of the chemical products 220 suitable for the function according to the number of rotations of the worm gear, so that the performance of the chemical products 220 to which the flame passage is connected varies depending on the type of the detonation function can be implemented.

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