[0051] Based on the above embodiment, the working process of the light and small-sized airborne suspension release device is briefly described below. In this embodiment, the working process of the light and small-sized airborne suspension release device is as follows:

[0052] 1) Device installation. First, connect the carrying mechanism to the aircraft or other carrier platform through screws, and then install the unlocking mechanism on the carrying mechanism. At this time, the carrying mechanism is in the initial state, the unlocking mechanism is in the locked state, and the unlocking slider of the unlocking mechanism is limited by the nut on the locking pin of the carrying mechanism to achieve connection.

[0053] 2) Load suspension. The light and small airborne suspension release device includes three steps from the initial state to the load mounting locking: First, the load hook contacts the locking tongues of the gripper I and the gripper II and continues to move, and the gripper I and the gripper II begin to close together until the gripper I and the gripper II are closed in place. Next, manually turn the rocker to clamp the gripper I and the gripper II, and insert the locking pin into the pin space of the center turntable II to complete the mechanism locking. Finally, observe whether the status indicator of the unlocking slide bar shows that it is locked in place. If it shows that it is in place, insert the safety pin into the safety pin socket of the unlocking slide bar.

[0054] 3) Load delivery. Load delivery is divided into two modes: manual unlocking and power-on automatic delivery. Manual unlocking is mainly for ground testing, device maintenance or other situations, and power-on automatic delivery is for load airdrop scenarios. Among them, manual unlocking and delivery includes two steps: first, pull out the safety pin, and insert the safety pin (or other tools) into the manual unlocking groove of the unlocking slide bar, use the rocker support as a fulcrum, pry the unlocking slide bar to move in the mounting base, and drive the locking pin out of the pin hole of the center turntable II; then, the connecting rod mechanism and the gripper are opened under the action of the gripper torsion spring and the gravity of the load to realize manual load delivery; after manual unlocking and delivery, the load-bearing mechanism is in the initial state, and the unlocking mechanism is in the locked state. Automatic release upon power-on includes three steps: first, pull out the safety pin; then, after reaching the specified position, the unlocker is powered on to unlock, the limit on the clamping rod is released, the pressure plate is lifted up by the pull rod spring and the locking push rod, and the unlocking slider pulls the locking pin out of the pin hole of the center turntable II under the action of the unlocking spring; finally, the connecting rod assembly and the gripper are opened under the action of the gripper torsion spring and the gravity of the load, realizing automatic release of the load upon power-on. After automatic release upon power-on, the load-bearing mechanism is in the initial state and the unlocking mechanism is in the unlocked state.

[0055] It should be noted that the above is only one embodiment of the technical solution of the present invention, and the structural dimensions can be changed according to actual needs to achieve load locking pre-release under different bearing capacities.

[0056] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention.
