[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 5 As shown, an automatic unlocking mechanism for exiting a machine comprises a housing 2, on which a coaxial unlocking turntable 1 and a driving turntable 3 are rotatably provided, a stopper 6 is fixedly provided, a slider 8 is slidably matched, and a ratchet 13 is swingably provided. An unlocking wire rope 16 is wound around the unlocking turntable 1, one end of the unlocking wire rope 16 is fixedly connected to the unlocking turntable 1, and the other end passes through the housing 2 and is connected to a traction lock. A driving wire rope 9 is wound around the driving turntable 3, one end of the driving wire rope 9 is fixedly connected to the driving turntable 3, and the other end One end passes through the block 6 and is fixedly connected to the slider 8. A spring 7 is sleeved on the driving wire rope 9 between the block 6 and the slider 8. Before installation, the pawl 13 is locked by the stop pin 15. The pawl 13 is stuck and hinders the rotation of the driving turntable 3. The spring 7 is in a compressed state. During installation, the pawl 13 is held by the aircraft guide rail and remains motionless. The stop pin 15 is removed. When leaving the plane, the pawl 13 is released, and the spring 7 is reset and unlocked through the driving wire rope 9, the driving turntable 3, the unlocking turntable 1, and the unlocking wire rope 16. The mechanism compresses the spring 7 to store energy before installation, temporarily locks it using the aircraft guide rail during installation, and unlocks the transmission parts of the mechanism itself using the spring 7 when leaving the plane. There is no need to hit the aircraft rolling rod, and the unlocking is reliable, avoiding man-made accidents, and there is no need to worry about hitting the aircraft floor.

During installation, the driving turntable 3 has a tendency to swing the pawl 13 upward under the action of the spring 7, and the aircraft guide rail holds the pawl 13 from the other side to provide a reaction force for it. Since the mechanism is installed together with the reloading system, it has enough deadweight and there is no need to worry about not being able to hold it down. Although the structure is simple, it is practical and reliable.

[0024] like Figure 2 and Figure 4As shown, in this embodiment, two driving steel wires 9 are symmetrically wound around the driving turntable 3, and the two driving steel wires 9 are respectively matched with two sets of blocks 6, springs 7 and sliders 8. As the most basic function, one driving steel wire 9 can be used to complete it. This is a preferred embodiment, the purpose is to superimpose the restoring force of the spring 7 to make the driving turntable 3 rotate faster. If more than three driving steel wires 9 are set, it is not convenient to arrange.

[0025] One unlocking steel rope 16 is wound around the unlocking turntable 1, or at least two unlocking steel ropes 16 are wound along the same direction, which can be arranged as required.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the unlocking turntable 1 has its own shaft, the driving turntable 3 is sleeved on the shaft and key-connected, one side of the axial direction of the driving turntable 3 is limited by the step of the shaft, and the other side is limited by the limiting ring 5, the limiting ring 5 is sleeved on the shaft and fixed by the screw 4.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, one end of the driving wire rope 9 is fixedly connected to the driving turntable 3 through a pin 11, and the other end is pressed into a pressing head 10, and the pressing head 10 is fixedly connected to the slider 8 through a nut 12.
