[0037] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0038] In the first aspect, referring to Figures 1 to 3 , this embodiment provides a pure mechanical logic unlocker, including: a base plate 1, a body cover 2, a cover plate 3, a locking tongue 4, a first locking rod 6, a second locking rod 7, a third locking rod 8, a fourth locking rod 9, a cartridge feeding associated locking rod 10, a dial plate 11, and a return spring 12.

[0039] The body cover 2 is installed on the base plate 1, and the front side of the body cover 2 is open.

[0040] The cover plate 3 is detachably connected to the opening of the body cover 2 by screws.

[0041] The locking tongue 4 longitudinally penetrates the body cover 2, and a compression spring 46 for moving it upward for reset is connected to the lower end of the locking tongue 4. At least two bumps 44 are longitudinally arranged at intervals on the front side of the locking tongue 4, and at least three bumps 44 are longitudinally arranged at intervals on the rear side. A stop block 41 is connected to the upper end of the locking tongue 4.

[0042] In a specific implementation scenario, a bottom plate 45 is detachably installed at the bottom of the body cover 2, a guide rod is fixed on the bottom plate 45, the guide rod is longitudinally slidably connected to the locking tongue 4, and the compression spring 46 is sleeved on the lower part of the guide rod. A top plate 47 is detachably installed at the top of the body cover 2, the upper part of the locking tongue 4 slidably penetrates the top plate 47, and the bump 44 is located below the top plate 47.

[0043] The first locking rod 6 is horizontally arranged and is located behind the locking tongue 4. One end of the first locking rod 6 is connected to a device for sensing that the artillery is in the direction firing range of ±30° 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 first locking rod 6, and the notch can be aligned or misaligned with the corresponding bump 44.

[0044] The second locking rod 7 is horizontally arranged and is located in front of the locking tongue 4. One end of the first locking rod 6 is connected to a device for sensing that the artillery is in the elevation firing range of 18° to 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.

[0045] The third locking lever 8 is horizontally arranged below the first locking lever 6 and is located at the rear side of the locking tongue 4. One end of the third locking lever 8 is connected by a steel wire rope 13 to a device for sensing that the artillery is in the azimuth firing range of +40° to +50°, and the other end slides through the right side of the body cover 2. A notch is provided on the third locking lever 8, and the notch can be aligned or misaligned with the corresponding convex block 44.

[0046] The fourth locking lever 9 is horizontally arranged below the second locking lever 7 and is located at the front side of the locking tongue 4. One end of the fourth locking lever 9 is connected by a steel wire rope 13 to a device for sensing that the artillery is in the elevation firing range of 0° to 20°, and the other end slides through the right side of the body cover 2. A notch is provided on the fourth locking lever 9, and the notch can be aligned or misaligned with the corresponding convex block 44.

[0047] The ammunition feeding related locking lever 10 is horizontally arranged below the third locking lever 8 and is located at the rear side of the locking tongue 4. One end of the ammunition feeding related locking lever 10 is connected by a steel wire rope 13 to a device for sensing that the ammunition feeding device is in the initial position, and the other end slides through the right side of the body cover 2. A notch is provided on the ammunition feeding related locking lever 10, and the notch can be aligned or misaligned with the corresponding convex block 44.

[0048] There are two deflector plates 11. One deflector plate 11 is fixed on the first locking lever 6 and the second locking lever 7 and can push the third locking lever 8 and the fourth locking lever 9 to the left; the other deflector plate 11 is fixed on the third locking lever 8 and the fourth locking lever 9 and can push the first locking lever 6 and the second locking lever 7 to the left.

[0049] There are five return springs 12. The five return springs 12 are installed on the right side of the body cover 2 and are used to move the first locking lever 6, the second locking lever 7, the third locking lever 8, the fourth locking lever 9 and the ammunition feeding related locking lever 10 to the right respectively.

[0050] The pure mechanical logic unlocker further includes a tail cover 5. The tail cover 5 is detachably connected to the right side of the body cover 2 and is used to cover the five return springs 12.

[0051] Combining the above content, when the first locking lever 6, the second locking lever 7, and the ammunition feeding associated locking lever 10 are simultaneously pulled out, the fourth locking lever 9 and the ammunition feeding associated locking lever 10 move leftward under the push of the corresponding dial 11, so that the notches on each locking lever are vertically aligned with the corresponding protrusions 44 on the locking tongue 4. At this time, the locking tongue 4 is in the unlocked state, and the firing device located above the stop 41 can press down the stop 41 and the locking tongue 4, so that the firing device can move downward to achieve the function of allowing the manual or electric firing operation of the firing device of the artillery to be effective when the artillery is in state 1; similarly, when the third locking lever 8, the fourth locking lever 9, and the ammunition feeding associated locking lever 10 are simultaneously pulled out, the first locking lever 6 and the second locking lever 7 are also pulled out, and the locking tongue 4 is in the unlocked state to achieve the function of allowing the manual or electric firing operation to be effective when the artillery is in state 2; after releasing the locking tongue 4, the locking tongue 4 moves upward under the action of the compression spring 46, and the first locking lever 6, the second locking lever 7, the third locking lever 8, the fourth locking lever 9, and the ammunition feeding associated locking lever 10 move rightward under the action of the corresponding return spring 12, so that the notches on the locking lever are staggered from the corresponding protrusions 44 on the locking tongue 4. At this time, the locking tongue 4 is in the locked state, and the downward movement of the locking tongue 4 is blocked by the interference between the protrusion 44 and the circumferential side surface of the locking lever. That is to say, when the locking tongue 4 is in the unlocked state, the manual or electric firing operation of the firing device of the artillery can make the firing device move downward; when the locking tongue 4 is in the locked state, the firing device cannot move downward to block the downward movement of the firing device, so as to achieve the purpose of being interlocked with the firing device. In particular, it can be seen from the above content that when the ammunition feeding associated locking lever 10 is not pulled out, regardless of whether the first locking lever 6, the second locking lever 7, the third locking lever 8, and the fourth locking lever 9 are pulled out, the locking tongue 4 is not in the unlocked state, and manual or electric firing operations are not allowed.

[0052] It should be noted that in this embodiment, preferably, the first locking lever 6, the second locking lever 7, the third locking lever 8, and the fourth locking lever 9 are configured simultaneously, 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 art); in other embodiments, only the first locking lever 6 and the second locking lever 7 can be configured to meet the requirements of state 1, that is, it is possible to choose to meet the requirements of all states or some states.

[0053] In the second aspect, referring to Figures 1 to 3 , this embodiment provides a locking tongue 4 assembly with a manual release function. The locking tongue 4 assembly with a manual release function includes the above-mentioned locking tongue 4, and in addition:

[0054] The stopper 41 has a cylindrical portion 42 which is rotatably sleeved on the upper end of the locking tongue 4, and a reset member such as a torsion spring is connected between the cylindrical portion 42 and the locking tongue 4. In this way, manual intervention can be carried out when the locking tongue 4 is not unlocked. By rotating the pressing block by 90°, the pressing block is staggered from the firing device above, and the function of allowing manual or electric firing operation of the firing device to be effective can still be achieved.

[0055] Further, a handle 43 is provided on the cylindrical portion 42 to facilitate manual rotation of the convex block 44.

[0056] Further, a limit pin for restricting the rotation of the stopper 41 relative to the locking tongue 4 is detachably connected to the cylindrical portion 42, so as to better restrict the rotation of the stopper 41 when the stopper 41 does not need to be rotated.

[0057] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Without conflict, the embodiments of the present 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 invention shall be included within the protection scope of the present invention.
