Bathroom lock device having an automatically unlocking structure

Abstract

A bathroom lock device includes an inner locking mechanism and a lock set. The inner locking mechanism consists of a manual control rod, an unlocking rotary plate and an inner actuating rotary plate. The manual control rod has a rotatable wheel while the unlocking rotary plate has a pair of actuating protrusions. In locking operation, the manual control rod is pressed to a locking position so as to limit a rotational movement of the inner actuating rotary plate. In unlocking operation, the manual control rod is returned to an unlocking position by turning a lever so as to permit turning the inner actuating rotary plate. When the lever turns the unlocking rotary plate, the actuating protrusions of the unlocking rotary plate smoothly push the rotatable wheel of the manual control rod so as to return the manual control rod to the unlocking position.
