Description

The present invention relates to an electric cylinder operated by electronic control (Patent No. 3782812) and an electric cylinder with an integrated dial collation mechanism capable of unlocking and interlocking the electric cylinder by operating a dial number for emergency use.

With electric cylinder locks up to now, if the condition requires emergency unlocking, that is, if the control unit breaks down due to an IC lock, etc., or if the voltage drops sharply due to a liquid leak from the battery-powered IC lock, etc., connect to an external power supply. In case of power disconnection due to disconnection of the power line of the electronic lock, power failure, power supply failure, etc., or if the key used for the card key or smartphone is lost, insert an emergency metal key into the key cylinder. It is common to unlock. However, it is rare to always have an emergency metal key, which is usually stored in the management room in apartments and apartments, and it takes time to find the metal key for each room in an emergency. Sometimes you can't find it.

When this emergency unlocking is required, it is required to be able to respond promptly and unlock it, and to take thorough security measures. Therefore, as a security measure, the operation switch mechanism is interlocked with the dial collation mechanism to unlock the operation via a capacitor.
