Electronic lock with emergency unlocking function and capable of improving anti-theft level

Abstract

The invention discloses an electronic lock with an emergency unlocking function and capable of improving the anti-theft level. The electronic lock comprises a lock housing. A motor is fixed in the lock housing, a worm connected with the motor meshes with a worm gear, a worm gear shaft is connected with a first gear, the first gear meshes with a second gear, a central shaft is fixed in the lock housing, the lower end of the central shaft is slidably connected with a third gear, a sliding sleeve slidably connected with the central shaft is fixed on the third gear, the second gear is positioned above the third gear and in is sliding contact with the sliding sleeve, a soft iron adsorption plate is arranged on the second gear, a soft iron adsorption ring fixedly connected with the sliding sleeve is arranged on the soft iron adsorption plate, an electromagnetic coil fixed in the lock housing is built in the soft iron adsorption ring, the third gear meshes with a fourth gear, and the fourth gear is fixedly connected with a lock core.

Description

technical field [0001] The invention relates to an electronic lock, in particular to an electronic lock with an emergency unlocking function which can improve the anti-theft level. Background technique [0002] Electronic locks are appreciated for eliminating the trouble of carrying keys, so more and more people choose to upgrade mechanical locks to electronic locks. There are many kinds of existing transformation methods. The basic structure is that a motor is fixed in the lock housing, and the worm connected to the motor meshes with the worm gear. The worm gear is coaxially connected with a gear, which is coaxially connected with one of the two reduction gears meshing, the other reduction gear meshes with the lock core drive gear, and the lock core drive gear is fixedly connected with the lock core; the motor is connected with the control circuit, and a lever clutch is also arranged outside the lock housing. When it is necessary to open / lock the door outdoors, input the p...

AI Technical Summary

Problems solved by technology

However, since the lever clutch is arranged outside the lock housing, and the lock core controlling the lever clutch is very small due to the limitation of the volume of the lock housing, the anti-theft performance is poor, which reduces the anti-theft level of the lock.
