Abstract:
1. A Lock assembly with a modified structure comprises: a lock body including an inner handle and an outer handle respectively disposed on an inner side and an outer end side of a door body; a latch and a bolt extensible into and retractable from an end side of a door frame; and an electrical locking mechanism disposed in the lock body for interfering retraction of the bolt; wherein the lock body further comprises a manual locking and controlling mechanism connected to the inner and outer handles and controlling locking and unlocking of the lock assembly; wherein the manual locking and controlling mechanism is provided with a rotation actuating piece linked to the inner and outer handles and a bolt moving piece controlling an extension and a retraction of the bolt, wherein the rotation actuating piece is linked to the bolt moving piece via a locking member to control the bolt for locking when the inner and outer handles are lifted, further wherein the rotation actuating piece is linked to the bolt moving piece via an unlocking member to control the bolt for unlocking when the inner and outer handles are pressed; wherein the rotation actuating piece is respectively linked to the inner handle and the outer handle via a rotation shaft, and a lock actuating piece and an unlock actuating piece are respectively provided on two opposite sides of a peripheral end of the rotation actuating piece, further wherein a first return spring applies a force on the lock actuating piece to make it return; wherein the bolt moving piece is rotatable disposed on an inner wall of the lock body, a positioning rotatable piece is provided at an axis of the bolt moving piece, at two opposite sides of the positioning rotatable piece are respectively provided a bolt moving lever bringing the bolt to extend and retract and a hook linked to the unlocking member, and at a peripheral end of the positioning rotatable piece are respectively provided a fan-shaped gear linked to the locking member and a fan-shaped plate cooperating with an electrical locking mechanism to lock the bolt; wherein, when the electrical locking mechanism identifies a correct electronic key, the electrical locking mechanism sends a signal to make the fan-shaped plate of the bolt moving piece lose a blocking action with respect to the electrical locking mechanism; wherein if the handle is pressed, the handle brings the rotation actuating piece to rotate clockwise via the rotation shaft because the unlock actuating piece of the rotation actuating piece abuts against the unlocking member, thereby bringing the unlocking member to rotate downwardly; wherein the rotation of the unlocking member brings the latch to retract inwardly and further brings the bolt moving piece to rotate clockwise, thereby driving the bolt moving lever to bring the bolt to retract inwardly, and meanwhile driving the locking member to slide upwardly, thereby accomplishing the unlocking.
