Background

At present, common burglary-resisting door is for taking manual unblock and not taking two kinds of full-automatic lock bodies of manual unblock, and the majority is motor drive, the current full-automatic lock body of taking manual unblock carries out machinery because of having the lock core hole simultaneously and unblanks, the structure is very complicated, motor automatic unlocking means and manual mechanical type structure of unblanking all separate the setting, not only the structure is complicated, and occupy too big position space in the lock body, lead to other parts to set up very compactly, the processing is difficult and with high costs, and the lock core is unblanked and can't accomplish electromechanical separation basically, when mechanical transmission unblanked, the key need drive the motor reversal, because motor transmission has multiple speed reduction and gear and between closely interlock to the lock core position, thereby need overcome very big reaction force moment of torsion when machinery is unblanked, cause very bad good. In order to avoid increasing the key unlocking burden, most of the full-automatic lock bodies on the market cancel an auxiliary lock hook (namely a multi-lock-point transmission rod), namely the full-automatic lock bodies without manual unlocking, but the lock bodies cannot realize manual quick unlocking in doors under emergency conditions, and have potential safety hazards.

The mechanical unlocking mode of most existing full-automatic lock bodies is single, the motor transmission needs to be waited for several seconds when emergency occurs, if the motor transmission fails, the key is replaced again to unlock, meanwhile, the reaction torque of the speed reducing motor needs to be overcome when the key is unlocked, and when fire occurs, local transmission parts are likely to deform to increase the transmission load of mechanical unlocking, even the key is twisted off or the door cannot be opened, and therefore potential safety hazards are greatly increased.
