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...
