Abstract

The present invention relates to an anti-burglary lock cylinder comprising a cylindrical axle inside which a rotary disk, a driving locking disk, a plurality of internal locking disks, a compression resilient element, and an external locking disk are sequentially mounted. A shell is fit over an outer circumference of the cylindrical axle. The cylindrical axle forms a notch in a sidewall thereof to receive a locking bar, which is controllably extended out of the notch to engage the shell for setting a locked condition. When a correct key is inserted, the locking bar is moved to recesses defined in the cylindrical axle and the locking disks to allow the cylindrical axle to be rotated within the shell for unlocking. The locking disks are made circular and the compression resilient element provide a compressible and deformable space for upwards shifting of the driving locking disk so that when a burglar attempts unlock by inserting an incorrect key, unlocking is prohibited and the locking disks are freely rotated within the cylindrical axle to protect the lock cylinder from being damaged.
