Abstract

A cylinder lock includes an outer rose disc having a middle opening, two locking holes, and an annular lateral rim formed with opposite engagement elements, a reinforcement structure having a first plate section that has a central hole aligned with the middle opening, and two passage holes aligned with the respective locking holes, two second plate sections extending transversely from two opposite ends of the first plate section, and two support sections respectively extending from the second plate sections to the lateral rim to engage the engagement elements. An outer drive tube extends through the middle opening and central hole. The reinforcement structure provides enhanced stiffness and robustness to two securing rods extending through the locking holes and the passage holes.
