PRESSURE RELIEF LATCH

摘要

A latch having a housing and a latch mechanism located within an interior portion of the housing. The latch mechanism includes an arm, a pair of socket screws, a pair of torsion springs, each of which is connected rotatably to the arm and engages a corresponding one of the pair of socket screws, a bolt mechanism attached rotatably to the housing, and a link attached pivotally to the arm and attached to the bolt mechanism. The socket screws are utilized to adjust loads on the springs. The bolt mechanism is movable between a first position, in which the arm and the link are toggled with one another under the loads of the springs and the bolt mechanism is adapted to engage an external structure, and a second position, in which the link and the arm are untoggled with one another and the bolt mechanism is disengaged with the external structure.
