Electric lock bolt control device for electronic combination lock

Abstract

The invention relates to an electric bolt control device for electronic code locks. The electric bolt control device comprises a lock body, a bolt, and a drive device. The drive device comprises an outer handle, an outer handle spring, and an outer drive jaw; the outer drive jaw in coaxial linkage with the outer handle spring is used for driving the bolt to unlock or lock; a stop is arranged beside the outer drive jaw. A motor, a motor control device and a stop drive unit are further disposed in the lock body; the stop drive unit can keep the stop at a stop unlocking position, where rotation of the outer drive jaw is unlimited, or a stop locking position, where the rotation of the outer drive jaw is limited, when the motor rotates positively or reversely to drive the stop drive unit; the motor control device is connected with a code entry device and can output a command to control the motor to positively or reversely rotate so as to arrive the stop unlocking position or to control the motor not to rotate, according to whether codes entered with the code entry device are correct or not. The electric bolt control device for electronic code locks is more reasonable in structure, power can be saved and failure rate is decreased.

Description

technical field [0001] The invention relates to the field of locks, in particular to an electronically controlled lockbolt control device for an electronic combination lock. Background technique [0002] With the increasing material wealth of the society, security and anti-theft has become a hot issue of social concern. "Lock" as the iron general guarding the door, people have higher and higher requirements for it, so various electronic combination locks are applied. However, the electronically controlled lock body of the existing electronic combination lock generally has the following problems: the use of coils or electromagnetic magnets and the use of motors to directly control the drive lock components to perform the opening and closing action, not only consumes a lot of power, is prone to failure, and there is no spare unlocking component , Once a failure occurs, it will cause a serious problem that the user cannot enter the room. Contents of the invention [0003] Th...
