Technical Field

The invention relates to the technical field of door and window lock bodies, in particular to an electromechanical separation electric lock body.

Background

At present common burglary-resisting door full-automatic lock body, the majority is motor drive, has the lock core hole simultaneously and unblanks mechanically, but the lock core unblanks 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 closely interlock between gear and gear to the lock core position to need overcome very big reaction force moment of torsion when mechanical unblanking, cause very bad good experience. Meanwhile, in order to avoid increasing the key unlocking burden of the existing full-automatic lock body, a secondary lock hook (namely a multi-locking-point transmission rod) is omitted in most of the full-automatic lock bodies on the market. 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.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide an electromechanical separated electric lock body which has a novel structure and multiple unlocking modes and is structurally separated from an electric unlocking structure and a manual unlocking structure.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: an electromechanical separation electric lock body comprises a lock box, a telescopic lock tongue arranged on the lock box, a lock core shaft, a driving motor, a rotating part connected with a door handle coaxial shaft and a transmission mechanism; the telescopic lock tongue is provided with a connecting rod, the lock core shaft is provided with a lock core shaft deflector rod and a lock core shaft gear part, and the lock core shaft deflector rod is pivoted with the connecting rod and drives the telescopic lock tongue to extend and retract through the connecting rod; the driving motor is coaxially connected with a driving gear; the rotating part is formed with a rotating part gear part; the transmission mechanism comprises a first gear, a second gear and a third gear, wherein the first gear is meshed with the gear part of the lock core shaft, the second gear is meshed with the driving gear, the third gear is meshed with the gear part of the rotating part, the rotating axes of the first gear, the second gear and the third gear are overlapped, a connecting pin shaft is connected between the first gear and the third gear to drive the first gear and the third gear to rotate synchronously, and meanwhile, an arc-shaped guide groove for the connecting pin shaft to pass through is formed in the second gear.

The invention has the beneficial effects that: according to the electromechanical separation electric lock body, after a key is inserted into the lock core shaft, the lock core shaft can directly drive the telescopic lock tongue to extend and retract through the lock core shaft deflector rod; the door handle is rotated to drive the rotating piece to rotate, so that the third gear is driven to rotate, and the first gear and the third gear synchronously rotate to drive the lock core shaft to rotate so as to drive the telescopic lock tongue to extend and retract; the driving gear of the driving motor can drive the second gear to rotate, when the second gear rotates to a certain angle, the connecting pin shaft touches the end point of the arc-shaped guide groove, so that the second gear drives the third gear to rotate and finally drives the telescopic spring bolt to stretch, and because the arc-shaped guide groove enables certain angle allowance to exist between the first gear and the third gear and the second gear, when the lock is unlocked through the lock core shaft and the door handle, the driving gear cannot be driven to rotate at once, and the electromechanical separation effect is achieved.

Preferably, the lock further comprises a first auxiliary lock hook which is arranged on the lock box and stretches and retracts in a sliding mode, the transmission mechanism is provided with a poking piece which drives the first auxiliary lock hook to stretch and retract, and the poking piece and the first gear or the third gear swing synchronously.

When the first secondary lock hook stretches, the rack can drive the transmission gear to rotate, so that the transmission gear drives the second secondary lock hook to stretch reversely and synchronously.

Preferably, the device also comprises a reset torsion spring which drives the connecting rod to reset. The return spring can drive the telescopic lock tongue to return.

Preferably, a guide connecting rod slide rail is arranged on the lock box, and a micro switch for controlling the driving motor is arranged at two ends of the slide rail.
