Description

A kind of drive mechanism that the emergency key of smart lock is unlocked

Technical field

The utility model belongs to lockset, and in particular to a kind of drive mechanism that the emergency key of smart lock is unlocked.

Background technology

Currently, the emergency key unlocking mode of common intelligent door lock is that key is inserted and rotated during lock core, by locking Core pushes directly on the push rod above clutch module and realizes unlocking.Since lock core and push rod are in same linear position, can directly use outer Power top pressure lock core gets on the push rod top in clutch module, can also unlock, and there are security risks for this structure.

Invention content

The purpose of this utility model is to provide a kind of biography that emergency key reasonable for structure, the good smart lock of safety is unlocked Dynamic structure.

To realize the utility model aim, the technical scheme that the utility model is provided is as follows：

The drive mechanism that the emergency key of smart lock is unlocked, including front panel, be equipped in front panel include lock core tapered end, If the clutch module of push rod, the push jack that sets return spring substantially vertical with the push rod of clutch module, the clutch module Push rod be equipped with pin, the push jack matches equipped with slanting kidney slot with the pin on the push rod, the tapered end Lock core be equipped with eccentric plectrum and matched with the push jack.

The beneficial effects of the utility model：

The utility model will be such that lock core and the push rod of clutch module is not located on same straight line, and lock core is staggered with push rod, this Sample will not push clutch pushrod movement even with external force top pressure lock core, improve safety and the anti-theft of lockset in this way.

The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
