Abstract
The invention discloses an electronic lock cylinder. The electronic lock cylinder comprises a rotating part which rotates in a lock shell to drive a spring bolt to enter and exit from a lock buckle on a door frame. An arc groove is formed in the outer circumference of the rotating part. The electronic lock cylinder further comprises a lock pin and an unlocking mechanism for driving the lock pin, wherein the lock pin rotates in the lock shell in the radial direction of the rotating part and is in sliding fit with the lock shell. When a door is locked, at least part of the lock pin stretches into the arc groove, the lock pin makes contact with the two circumferential side walls of the arc groove so that the rotation angle of the rotating part can be limited within the angle range corresponding to the arc groove, and the rotating part cannot drive the spring bolt to leave the lock buckle within the angle range. When the door is unlocked, the unlocking mechanism is used for driving the lock pin to move in the radial direction and leave the arc groove so that the limitation to the rotation angle of the rotating part can be removed, and the rotating part can drive the spring bolt to leave the lock buckle. According to the lock cylinder, the door can be opened only by adding an unlocking action indoors, and existing tools for stealing via a door viewer cannot drive the lock cylinder to unlock the spring bolt.
