Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to an anti-peeping key structure and a smart lock. Background Technology

[0002] A peephole, also known as a peephole, is a small optical device installed on the door of a residential apartment. Its main purpose is to allow residents to observe the outside environment when the door is closed. With a peephole installed, people inside the apartment can clearly see outside, but those outside cannot easily see inside. Currently, peepholes have become a necessity for residential doors, serving a certain degree of security and burglary prevention.

[0003] However, installing a peephole requires a hole to be made in the door to accommodate it. This could allow criminals to damage the peephole, insert a special tool through the hole, press the door handle from the inside, and then enter the house, thus compromising the safety of people and property inside.

[0004] To address the issue of unlocking via the peephole, existing door locks incorporate a clutch assembly in the lock cylinder. The clutch assembly is triggered by changes in the position of the clutch disc, causing the lock cylinder to be in a free state, preventing the door from being opened via the inner handle. A toggle mechanism is used to change the clutch disc position, as seen in patent 202322472684.2. However, this toggle mechanism is complex, resulting in higher production and assembly costs. Furthermore, its lateral movement to change the clutch disc position is limited by lateral space, making it unsuitable for integration with electric mechanisms. Utility Model Content
