Door installation mechanism for smart lock system

摘要

A door mount mechanism is to be mounted onto a door for rotating a thumb turn of a door lock. The door mount mechanism includes a casing, a rotatable component and an intermediate coupling. The casing is for abutting against the door, and defines a receiving space that is adapted for receiving the door lock. The rotatable component is coupled rotatably to the casing. The intermediate coupling includes a first coupling segment connected co-rotatably to the rotatable component, and a second coupling segment connected co-rotatably to and linearly movable relative to the first coupling segment and for driving rotation of the thumb turn of the door lock such that the thumb turn is co-rotatable with the rotatable component.
