An embodiment of a rotor type safety loading apparatus using a leaf spring according to the present invention will be described in detail with reference to FIGS. 3 to 5.

The rotor type safety loading device using the leaf spring according to the present invention includes a semi-circular rotor member 200 rotatably coupled to the base support 100.

The base supporter 100 is positioned on the base member 110, the base member 110, and the first rotor support member 120 and the base member to which the rotor rotation shaft 210 of the rotor member 200 is rotatably connected. The second rotor support member 130 may be disposed on the 110 and spaced apart from the first rotor support member 120, and the rotor rotation shaft 210 of the rotor member 200 may be rotatably connected thereto.

The first rotor support member 120 and the second rotor support member 130 are positioned opposite to each side of the rotor member 200 so that both ends of the rotor rotation shaft 210 are rotatably connected to each other.

Both ends of the rotor rotation shaft 210 are rotatably connected to the first rotor support member 120 and the second rotor support member 130 to rotatably support the rotor member 200.

For example, the rotor member 200 may have a semicircular shape that may be positioned in a loaded state while being rotated by an inertial force by a center of gravity spaced apart from the center of rotation.

The rotor member 200 is locked by the locking unit 400 in the non-loaded position and is fixed in position. When the lock is released by the inertia force after firing, the rotor member 200 is rotated by the inertia force by the center of gravity spaced apart from the rotation center. It is placed in the loaded state to apply the detonation signal.

The base support 100 may further include a non-loading position supporting member 500 which is positioned so as to protrude on the base member 110 to support the position of the rotor member 200 in an unloading state.

The non-loading position supporting member 500 may include the rotor member 200 such that the rotor member 200 may be stopped at a reference position in which the rotor member 200 is in a non-loading state, that is, a reference position locked by the locking unit 400. By supporting one side of the contact so that the rotor member 200 can be easily positioned in an unloaded position, that is, an accurate position that can be locked by the locking unit 400.

The rotor member 200 has a semicircular shape in a non-loading position in which a straight portion 200a and an arc portion 200b are provided on the outer circumferential surface, and the straight portion 200a is positioned to face the base member and is inclined at a predetermined angle. For example, the non-loading position supporting member 500 contacts and supports the straight portion 200a.

The locking unit 400 is positioned to be movable on the base support 100 and is moved by inertia when firing the inertial pin member 410 and inertial pin member 410 to support the rotor member 200 at the non-loading position by walking. ) And a locking spring member 420 which is compressed when the inertial pin member 410 is moved by inertia.

The inertial pin member 410 is inserted into the inertial pin insertion portion 111 positioned in the base member 110 and elastically supported by the locking spring member 420 to be protruded on the base member 110.

In the rotor member 200, a pin catching groove portion 200c in which a part of the inertial pin member 410 is inserted in the non-loading position is positioned, and the pin catching groove portion 200c is located in the straight portion 200a. do.

The rotor member 200 has a loading lock groove 220 in which the inertial pin member 410 is inserted at the loading position.

The inertial pin member 410 is retracted by the inertial force generated after firing and is further inserted into the inertial pin insertion portion 111 to compress the locking spring member 420, and the rotor member 200 is placed in a loaded state. It is inserted into the loading lock groove 220 of the rotor member 200 which is protruded onto the base member 100 again by the elastic restoring force of the locking spring member 420 in a state where the force of inertial force is lowered. The position of the rotor member 200 is fixed.

Meanwhile, the leaf spring member 300 is in contact with the outer circumferential surface of the rotor member 200, and the leaf spring member 300 slows down the rotational speed of the rotor member 200 when the rotor member 200 is rotated.

On the outer circumferential surface of the rotor member 200, a spring engaging value 231 to which the end of the leaf spring member 300 is inserted is caught and spaced apart in the circumferential direction, and a plurality of speed control gears 230 are positioned.

The base member 110 is positioned to protrude a spring support 310 which is protruded to support the leaf spring member 300 at a predetermined height.

The leaf spring member 300 is seated and fixed on the spring support part 310, and is positioned such that one end portion is inserted into and engaged with the spring latch 231.

When the rotor member 200 rotates, the leaf spring member 300 is bent and unfolded, and an end thereof is separated from the spring latch 231 of the speed control gear 230, and the spring of the speed control gear 230 again. The rotation speed of the rotor member 200 is adjusted while repeating the insertion in the locking tooth 231.

In addition, the spring latch 231 has a pawl structure of the ratchet to prevent the rotation in the reverse direction of the direction in which the rotor member 200 is rotated by inertial force after firing, that is, in the reverse direction of the forward direction rotated to the loading position. Take one example as an example.

The speed control gear unit 230 has a ratchet structure to enable only the forward rotation in which the rotor member 200 is rotated to the loading position, and reverse rotation is prevented to prevent malfunction during loading.

In more detail, the loading lock groove 220 is located in the speed control gear 230, but is located in the center in the width direction so that the spring latch 231 can be located on both sides.

The speed control gear unit 230 is positioned at both sides of the loading lock groove 220 at the portion where the loading lock groove 220 is positioned so that the leaf spring member 300 may be caught, and thus the plate spring member 300 may be moved to the loading position. The deceleration can be made stable.

That is, the leaf spring member 300 is inserted into the spring catching 231 of the speed control gear 230 so that the end of the rotor member 200 in the forward rotation of the spring is released in the spring catching 231, the spring again The rotation speed of the rotor member 200 is adjusted while repeating the insertion into the catch 231, and when the rotor member 200 is reversely rotated, the rotor member is caught by the spring catch 231 of the pawl structure. The reverse rotation of the 200).

A portion of one end side is fixedly positioned to be inserted into the spring latch 231.

The leaf spring member 300 controls the time during which the rotor member 200 is rapidly rotated to one side by the acceleration of the bullet while the inertia weight member is moved and the rotation restriction of the rotor member 200 is released after the shot is fired. It controls the time, that is, the point of detonation.

As an example, when the bullet is rapidly accelerated, the rotor member 200 may be rapidly rotated by an inertial force acting in a direction opposite to the direction in which the bullet travels, whereby the rotor member 200 may be damaged by recoil or impact. There is a fear that the timing of the detonation cannot be controlled accurately.

The leaf spring member 300 controls the rotational speed of the rotor member 200 which is rotated by the acceleration of the bullet to prevent damage of the rotor member 200 due to the sudden rotation, and also accurately controls the timing of detonation after the shot is fired. In this case, the error of the timing of detonation can be minimized.

Referring to FIG. 5, the rotor member 200 is caught by the inertial pin member 410 inserted into the pin locking groove 200c while being supported by the non-loading position supporting member 500 in a non-loading position. It remains fixed, that is, it is placed in an unaligned state so that the explosion series is kept safe.

6 and 7 are views showing an operation example of the rotor type safety loading device using the leaf spring according to the present invention.

Referring to FIG. 6, the inertial pin member 410 is retracted by the inertia force after firing and is further inserted into the inertial pin insertion part 111, thereby compressing the locking spring member 420 and being separated from the pin locking groove 200c. The lock of the rotor member 200 is released.

If the lock by the inertial pin member 410 is released by the inertial force after the shot is fired, the rotor member 200 is rotated in a forward direction which can be positioned in a loaded state by the inertial force, and the leaf spring member 300 is spring-locked. The rotational speed of the rotor member 200 is adjusted while being alternately repeated in the tooth 231 and being repeatedly inserted into the spring latch 231.

7 is a cross-sectional view illustrating an example in which the rotor member 200 is rotated and finally positioned at a loading position.

Referring to FIG. 7, when the rotor member 200 is rotated by an inertial force and finally positioned to a loaded position, the inertial pin member 410 is returned to its original position while being inserted into the loading lock groove 220 and the rotor member 200.
