ABSTRACT:
A rekeyable lock cylinder structure comprises a shell, a plug assembly and a plurality of pin groups. The shell has a hollow cylindrical portion and defines a central axis. The plug assembly is disposed within the hollow cylindrical portion of the shell and comprises a plug body and a sliding block. The plug body has a front section, a driving portion, a middle section connecting the front section and the driving portion, a coupling cavity recessed from the front section and the middle section and a plurality of lower pin holes formed in the middle section and communicating with the coupling cavity. The sliding block, which is disposed at the coupling cavity of the plug body and able to move parallel to the central axis of the shell, has a plurality of pin-sliding grooves and a keyhole communicating with the pin-sliding grooves. Each pin group at least comprises a lower pin that includes an upper locking piece, a lower locking piece able to engage with the upper locking piece and a resilient member disposed between the upper locking piece and the lower locking piece. The lower pin is moveably disposed within at least one lower pin hole of the plug body and at least one pin-sliding groove of the sliding block.
