HUMANIZED CONVENIENT DOOR LOCK

摘要

A humanized convenient door lock includes a lock housing, a latch, a security hook, an outside handle operation mechanism, an inside handle operation mechanism, a cylinder driving mechanism, and an inside deadlocking rotary knob driving mechanism. The inside handle operation mechanism drives and controls the latch, the security hook, and the inside deadlocking rotary knob driving mechanism. To open the door, it only needs a one-time operation by pressing down a handle, thereby providing ease and convenience. The design is a humanized one, making it particularly suit for the needs of the disabled and the elderly and for urgent door opening.
