Abstract

The disclosure discloses a ball lock cylinder and a lock thereof. The ball lock cylinder comprises a key, a lock case, an outer lock liner, a double-opening and shifting support assembly and an inner lock liner, wherein an oblong hole which penetrates through is formed at a part, corresponding to a keyhole port of the outer lock liner and the inner lock liner, of the key, and the oblong hole is pin-connected with an annular ball which eccentrically rolls in a keyhole; a first groove and a second groove which are in yielding fitting with the annular ball in the key are respectively formed in a lower side and an upper side of the keyhole, in each of the outer lock liner and the inner lock liner; flat-end female beads which can slide up and down and are matched with the annular ball are vertically arranged in longitudinal directions of the outer lock liner and the inner lock liner, and centers of the flat-end female beads are further sleeved with cone-end flat-tail male beads which can slide up and down; and an annular plane of an outer edge of each flat-end female bead is in contact with the annular ball in the key, and a lower cone end face of each cone-end flat-tail female bead is matched with a tooth socket formed in the key beside the annular ball. During unlocking, a mutual reverse movement mode in which the flat-end female beads rise and the cone-end flat-tail male beads fall is formed, so that coping the key by 3D printing is avoided, technical unlocking is effectively avoided and the anti-theft ability is improved.
