Description

The present invention relates to an integrated electric cylinder with a dial collation mechanism that integrates an electric cylinder operated by electronic control and an emergency dial collation mechanism and can bring the electric cylinder into an unlocking interlocking state by operating a dial number. Further, the present invention relates to an electric cylinder with a dial collation mechanism in which a dial password can be set from the outside of the housing by a push pin bar.

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 suddenly drops due to liquid leakage from the battery-powered IC lock, etc., connect to an external power supply. If the power line of the electronic lock is broken, the power is cut off, or the power supply is out of order, 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, and it is usually stored in the management room in apartment houses and apartments, and it takes time to find the metal key for each room in an emergency. Sometimes I couldn't find it.
When it is necessary to unlock in an emergency, it is required to be able to quickly respond and unlock and to take thorough security measures. As a security measure, a dial collation mechanism is linked with an operation switch mechanism to form a capacitor. We invented an electric cylinder with a security dial collation mechanism that can be operated and unlocked via.

In this electric cylinder with a dial collation mechanism for crime prevention, in order to reselect a password in the dial collation mechanism, the main housing containing the dial collation mechanism in the dial module is disassembled and the dial number change lever is used. It was inconvenient because I had to. In order to eliminate the inconvenience, we would like to be able to reset the password by operating the push pin bar from the outside of the housing.
