LOCKING STATE CHECKER

摘要

PURPOSE: A locking state checker is provided to eliminate the possibility of a wrong operation and to guarantee all checking results. CONSTITUTION: A leaf spring is inserted into a V shaped groove installed in instructing bars(2,5) to support the bars. Then, a key body(4) is inserted into the hole of a lock and a body(3) is rotated clockwise. Then, a door is locked since the force of leaf springs is stronger than the resisting force of the lock. After the locking, the key body is fixed and the body is rotated. Thus, the instructing bars are moved to the opposite direction to be supported by the leaf springs.
