[0047] The second locking rod 7 is horizontally arranged and is located at the front side of the locking tongue 4. One end of the first locking rod 6 is connected to a device for sensing that the artillery is within the elevation firing range of 18° - 70° through a steel wire rope 13, and the other end slidably penetrates the right side of the body cover 2. A notch is provided on the second locking rod 7, and the notch can be aligned or misaligned with the corresponding bump 44.

[0048] The third locking rod 8 is horizontally arranged below the first locking rod 6 and is located at the rear side of the locking tongue 4. One end of the third locking rod 8 is connected to a device for sensing that the artillery is within the direction firing range of +40° - +50° through a steel wire rope 13, and the other end slidably penetrates the right side of the body cover 2.

[0049] The fourth locking rod 9 is horizontally arranged below the second locking rod 7 and is located at the front side of the locking tongue 4. One end of the fourth locking rod 9 is connected to a device for sensing that the artillery is within the elevation firing range of 0° - 20° through a steel wire rope 13, and the other end slidably penetrates the right side of the body cover 2. A notch is provided on the fourth locking rod 9, and the notch can be aligned or misaligned with the corresponding bump 44.

[0050] The ammunition feeding associated locking rod 10 is horizontally arranged below the third locking rod 8 and is located at the rear side of the locking tongue 4. One end of the ammunition feeding associated locking rod 10 is connected to a device for sensing that the ammunition feeding device is in the initial position through a steel wire rope 13, and the other end slidably penetrates the right side of the body cover 2. A notch is provided on the ammunition feeding associated locking rod 10, and the notch can be aligned or misaligned with the corresponding bump 44.

[0051] There are two dial plates 11. One of the dial plates 11 is fixed on the first locking rod 6 and the second locking rod 7 and can push the third locking rod 8 and the fourth locking rod 9 to the left; the other dial plate 11 is fixed on the third locking rod 8 and the fourth locking rod 9 and can push the first locking rod 6 and the second locking rod 7 to the left.

[0052] There are five reset springs 12. The five reset springs 12 are installed on the right side of the body cover 2 and are used to move the first locking rod 6, the second locking rod 7, the third locking rod 8, the fourth locking rod 9, and the ammunition feeding associated locking rod 10 to the right respectively.

[0053] The pure mechanical logic unlocker further comprises a tail cover 5 , which is detachably connected to the right side of the body cover 2 and is used to cover the five return springs 12 .

[0054] In combination with the above content, when the first locking rod 6, the second locking rod 7 and the ammunition feeding associated locking rod 10 are pulled out at the same time, the fourth locking rod 9 and the ammunition feeding associated locking rod 10 move left under the push of the corresponding paddle 11, so that the notches on each locking rod are aligned with the corresponding protrusions 44 on the lock tongue 4. At this time, the lock tongue 4 is in an unlocked state, and the firing device located above the stopper 41 can press the stopper 41 and the lock tongue 4 downward, so that the firing device can move downward, so as to realize the function of allowing manual firing or electric firing operation of the artillery firing device to be effective when the artillery is in state 1; similarly, when the third locking rod 8, the fourth locking rod 9 and the ammunition feeding associated locking rod 10 are pushed out at the same time, the fourth locking rod 9 and the ammunition feeding associated locking rod 10 move left under the push of the corresponding paddle 11, so that the notches on the locking rods are aligned with the corresponding protrusions 44 on the lock tongue 4. At this time, the lock tongue 4 is in an unlocked state, and the firing device located above the stopper 41 can press the stopper 41 and the lock tongue 4 downward, so that the firing device can move downward, so as to realize the function of allowing manual firing or electric firing operation of the artillery firing device to be effective when the artillery is in state 1. When the rod 10 is pulled out at the same time, the first locking rod 6 and the second locking rod 7 are also pulled out, and the lock tongue 4 is in an unlocked state, so as to realize the function of allowing manual firing or electric firing operation to be effective when the artillery is in state 2; after the lock tongue 4 is released, the lock tongue 4 moves up under the action of the compression spring, and the first locking rod 6, the second locking rod 7, the third locking rod 8, the fourth locking rod 9 and the ammunition feeding associated locking rod 10 move right under the action of the corresponding reset spring 12, so that the notch on the lock rod is staggered with the corresponding protrusion 44 on the lock tongue 4, and the lock tongue 4 is in a locked state, and the downward movement of the lock tongue 4 is blocked by the interference between the protrusion 44 and the circumferential side of the lock rod. That is, when the lock tongue 4 is in an unlocked state, the manual firing or electric firing operation of the firing device of the artillery can cause the firing device to move downward; when the lock tongue 4 is in a locked state, the firing device cannot move downward to block the downward movement of the firing device, thereby achieving the purpose of interlocking with the firing device. In particular, it can be seen from the above content that when the bullet feeding associated locking rod 10 is not pulled out, no matter whether the first locking rod 6, the second locking rod 7, the third locking rod 8 and the fourth locking rod 9 are pulled out, the locking tongue 4 is not in an unlocked state, and manual firing or electric firing operations are not allowed.

[0055] It should be noted that in this embodiment, preferably, the first locking rod 6, the second locking rod 7, the third locking rod 8 and the fourth locking rod 9 are configured at the same time, so that the pure mechanical logic unlocker can meet the requirements of the artillery in state 1 and state 2 (state 1 and state 2 mentioned in the background technology); in other embodiments, only the first locking rod 6 and the second locking rod 7 can be configured to meet the requirements of state 1, that is, it can be selected to meet the requirements of all states or some states.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Without conflict, the embodiments of this application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
