The aircraft door gust lock device 100 according to the present invention has two modes of locking and unlocking, and the movement of the aircraft door gust lock device 100 in the two modes of locking and unlocking will be described below.
Lock
Fig. 3 and 5 are views showing a completely locked state of the aircraft door gust lock device 100 according to the present invention, in which fig. 3 is a schematic view showing positions of respective members in the completely locked state of the aircraft door gust lock device 100, and fig. 5 is a schematic view showing a relative position of the latch hook 121a and the latch bar 111 in the completely locked state of the aircraft door gust lock device 100.
As shown in fig. 3 and 5, when the operator opens the door DC of the aircraft, the latch hook 120 of the aircraft door gust lock device 100 rotates around the rotation shaft together with the hinge arm HA, and the latch hook 121a of the latch hook 120 formed on the first ratchet 121 comes into contact with the latch 111 of the latch part 110 near the end of the door DC opening process, and the extendable rod 124 is still at the first length. As the door DC is further opened, the telescopic rod 124 is compressed, so that the latch hook 121a formed on the first ratchet wheel 121 rotates until the latch hook 121a is completely hooked with the latch 111, and at this time, the door DC is opened to the maximum position, and the telescopic rod 124 is at the second length, and the first protrusion 122a of the second ratchet wheel 122 abuts against the second catch 121c of the first ratchet wheel 121, and the latch hook 121a is locked with the latch 111 under the combined action of the compression spring 125. In addition, as shown in fig. 2, since the torsion spring 136 is in a torsion state at this time, a torque is provided to the handle crankshaft 134 and is transmitted to the second ratchet 122 through the transmission rod 140, and the second ratchet 122 is prevented from rotating back, thereby further reliably abutting the second ratchet 122 against the first ratchet 121, so that the latch hook 121a is locked.
Unlocking of
Fig. 4 and 6 are diagrams showing an unlocked state of the aircraft door gust lock device 100 according to the present invention, wherein fig. 4 is a schematic diagram showing positions of respective members in the unlocked state of the aircraft door gust lock device 100, and fig. 6 is a schematic diagram showing a relative position of the latch hook 121a and the latch 111 in the unlocked state of the aircraft door gust lock device 100.
As shown in fig. 4 and 6, when the operator wants to close the door DC of the aircraft, the handle 131 is pushed first, the handle crank 134 rotates, and the second ratchet 122 is pushed to rotate around its axis by the transmission rod 140, and at this time, the first protrusion 122a of the second ratchet 122 is out of contact with the second catch 121c of the first ratchet 121. Subsequently, under the extending action of the telescopic rod 124, the latch hook 121a formed on the first ratchet 121 rotates clockwise around its axis and moves away from the latch 111 of the latch part 110 until completely disengaging from the latch 111, and becomes an unlocked state.
According to the above configuration, in the aircraft door gust lock device 100 of the present invention, when the door CB of the aircraft is completely locked, the first protrusion 122a of the second ratchet 122 abuts against the second stopper 121c of the first ratchet 121, and the stopper pin 123 abuts against the third stopper 121d of the first ratchet 121, so that the lock between the latch part 110 and the latch hook part 120 can be maintained by the second ratchet 122 and the stopper pin 123.
In the aircraft door gust lock apparatus 100 according to the present invention, when the door CB of the aircraft is completely locked, the extendable rod 124 is pushed and retracted, and the compression spring 125 fitted over the extendable rod 124 applies an urging force in the extension direction, so that the first protrusion 122a of the second ratchet 122 can be more securely brought into contact with the second stopper 121c of the first ratchet 121, thereby more securely locking the latch 110 and the latch hook 120.
In the aircraft door gust lock apparatus 100 according to the present invention, when the door CB of the aircraft is completely locked, the torsion spring 136 provided in the operating unit 130 is in a twisted state, and applies a torque to the handle crank 134, and the torque is transmitted to the second ratchet 122 through the transmission rod 140, thereby preventing the second ratchet 122 from rotating, and thus preventing the latch unit 110 from being disengaged from the latch unit 120, and improving the safety of locking.
In addition, according to the above-mentioned structure, in the aircraft door gust lock device 100 of the present invention, the latch part 110 is fixedly installed on the door jamb CD of the door of the aircraftFLThe locking hook 120 is mounted on the hinge arm HA, and the operation portion 130 is also mounted on the hinge arm HA, so that when the aircraft door gust lock device 100 is installed or disassembled or the aircraft door gust lock device 100 is replaced, other mechanisms of the door DC are not affected, and the disassembly operation of other mechanisms of the door DC is not required. In addition, the aircraft cabin door gust lock device 100 is simple in structure, accurate in positioning, convenient to process and install, capable of reducing assembly cost and improving locking and unlocking accuracy.
