Grade swing arm 15 continues to rotate, and contacts with position limit arm 13,13 one end of position limit arm is stuck in the limit of 15 axis client periphery of level-one swing arm
Incision site, while level-one swing arm 15 and 13 cylinder contacts of position limit arm, realize the bidirectionally limited of level-one swing arm 15.Second level swing arm 10
Continue to rotate counterclockwise, until separating mechanism triggering unlock, second level swing arm are contacted with spacer pin 11 and stopped operating, completion was unlocked
Journey.
Self- recoverage process of the present invention is the inverse process of unlocking process, and after trigger device is completed to unlock, second level swing arm 10 exists
It is rotated clockwise under the action of the torsion spring force of second level swing arm reduction torsion spring 9, goes to and contacted with 13 pin shaft of position limit arm, and push
Pin shaft movement, pin shaft is rotated centered on position limit arm installation pin shaft, as shown in figure 4, position limit arm 13 discharges level-one pendulum at this time
The limit of arm 15, level-one swing arm 15 are rotated counterclockwise under the action of the spring force of level-one swing arm reduction torsion spring 14, are turned to
The position of the first release boss on wheel 2, since memory alloy wire spring 4 has powered off, in cooling procedure, memory alloy wire is drawn
Power is smaller, reset spring 4 pull Kev drawstring spring 3, rotate clockwise runner 2, when rotating 90 °, the limited post of runner 2 with
The positive stop lug boss of casing 1 contacts, and stops operating, at this point, completing self- recoverage movement.
Self- recoverage trigger mechanism provided in an embodiment of the present invention is unlocked by memory alloy wire driving trigger mechanism, is remembered
Recall the input control drawing force that alloy wire passes through electric power, can more accurately set releasing force.In addition, being locked in self- recoverage trigger mechanism
When tight state, by the multistage arm of force, the constraint of runner and reset spring, so that lesser coupling mechanism force can be stablized, locking is big to be carried
Lotus is, it can be achieved that reliable locking to load.Self- recoverage trigger mechanism is added in unlock trigger by the energization of memory alloy wire
Heat, so that generate stretcher strain by phase transformation, by the effect of reset spring, multistage swing arm reduction torsion spring, so that swing arm at different levels,
Runner, position limit arm can return to original state, to realize the self-recovering function of trigger mechanism.Memory alloy wire and each connection
After unlock, self-recovering function can be realized so as to reuse without other toolings, to realize trigger mechanism
It reuses.
The content that description in the present invention is not described in detail belongs to the well-known technique of those skilled in the art.
