ABSTRACT:
A press-buckled lock having a press buckle is used so that the operation of locking and unlocking can be performed rapidly. By pressing the buckle, the door can be locked rapidly. When the inner handle is rotated, the press buckle is separated rapidly to unlock. Other than making the operation easy, the installation of the press buckle at the inner handle of a lock will reduce the manufacturing cost and cause the operation to be easy. Thereby the cost is reduced. By pressing the press buckle, a lock can locked rapidly; when rotating the inner handle or inserting a specific key into the lock core, the press buckle will separate rapidly so as to unlock the lock; thus, the press buckle in the lock has the effect of controlling the locking and unlocking operation rapidly.
