[0018] Reference should be made to Figure 1A quick-release mechanism for connecting airborne weapon compartments includes a left connecting lug 1, a tension spring 2, a movable lug 3, a lever 4, a right connecting lug 5, a left compartment 6, a locking shaft 7, a rotating shaft 8, and a right compartment 9. The left connecting lug 1 is bolted to the left compartment 6, the locking shaft 7 is mounted on the left connecting lug 1, the right connecting lug 5 is bolted to the right compartment 9, the rotating shaft 8 is mounted on the right connecting lug 5, and the lever 4 is located on the upper surface of the right connecting lug 5. The lower part of the lever 4 is provided with a wedge surface for wedging into the right end of the movable ear 3 and the right connecting lug 5. The movable ear 3 is movably mounted on the rotating shaft 8, that is, the movable ear 3 can rotate clockwise or counterclockwise along the rotating shaft 8. One end of the tension spring 2 is connected to the movable ear 3, and the other end of the tension spring 2 is fixed to the right compartment 9 located above the rotating shaft 8. The left end of the movable ear 3 is provided with a locking groove for locking the locking shaft 7. The lever 4 intermittently contacts the right end of the movable ear 3 as the movable ear 3 moves.

[0019] In this embodiment, the left connecting lug 1 is provided with a locking shaft hole for installing the locking shaft 7.

[0020] In this embodiment, the wedge surface provided at the lower part of the lever 4 is a boss wedge surface.

[0021] In this embodiment, the right connecting lug 5 is provided with a pivot hole for mounting the pivot 8.

[0022] In this embodiment, the rotating shaft 8 is provided with an ear piece shaft hole for mounting the movable ear piece 3.

[0023] In this embodiment, in the initial assembly state, the movable lug 3 is in a pulled-up state under the action of the tension spring 2, and the wedge surface of the boss of the lever 4 does not contact the movable lug 3. During assembly, the right compartment section 9 is kept fixed, and the left compartment section 6 is connected to the right compartment section 9. During this process, the locking shaft 7 mounted on the left compartment section 6 will move to the right together with the left compartment section 6. After the locking shaft 7 slides into the locking groove at the left end of the movable lug 3, it drives the movable lug 3 to rotate counterclockwise around the rotating shaft 8. The locking groove at the left end of the movable lug 3 moves downward to lock onto the locking shaft 7. At the same time, the right end of the movable lug 3 is lifted upward. This movement trend will continue. Hold the left compartment section 6 and the right compartment section 9 until their end faces are tightly pressed together. After the end faces of the left compartment section 6 and the right compartment section 9 are pressed together, rotate the lever 4 clockwise. The wedge-shaped boss at the lower part of the lever 4 will wedge into the gap between the right end of the movable lug 3 and the upper surface of the right connecting lug 5. During the process of rotating the lever 4 to wedge into the gap, the movable lug 3 also tends to rotate counterclockwise around the pivot 8, causing the locking groove at the left end of the movable lug 3 to clamp the locking shaft 7 downwards until the gap between the locking groove at the left end of the movable lug 3 and the locking shaft 7 is eliminated. After assembly, the relative positional relationship of each component of the compartment connection quick disassembly mechanism is as follows: Figure 2 As shown;

[0024] When disassembling, only need to rotate the handle 4 counterclockwise by 90°, until the convex wedge surface of the handle 4 is separated from the right end of the movable ear 3, under the action of the tension spring 2, the left end of the movable ear 3 is pulled up, and the left cabin section 6 and the right cabin section 9 can be smoothly separated.
