Pin Mechanism

摘要

Pin release mechanism comprising: a release pin axially movable from a first position to a second position; a bias spring biasing the release pin towards the second position; a pull rod interacting with ball bearings, the pull rod having a locked position in which ball bearings radially interfere with movement of the release pin and prevent movement of the release pin from the first position to a second position, and an unlocked position in which the ball bearings may move radially relative to the pull rod to allow the release pin to move from the first position towards the second position; a solenoid, which when actuated moves the pull rod toward the unlocked position; and a bias pin coupled to the pull rod, biased by a spring pushing between the release pin and the bias pin, to bias the bias pin and the pull rod toward the second, unlocked direction.

1. A pin release mechanism comprising:
a release pin axially movable from a first position to a second position; a bias spring biasing the release pin towards the second position; a pull rod interacting with a plurality of ball bearings, the pull rod having a locked position in which a plurality of ball bearings radially interfere with movement of the release pin and prevent movement of the release pin from the first position to a second position, and an unlocked position in which the plurality of ball bearings may move radially relative to the pull rod to allow the release pin to move from the first position towards the second position; a solenoid, which when actuated moves the pull rod toward the unlocked position; and a bias pin coupled to the pull rod, biased by a spring pushing between the release pin and the bias pin, to bias the bias pin and the pull rod toward the second, unlocked direction.
