Title:
CYLINDER LOCK WITH DOUBLE OPENING ANGLES AND SAFETY LOCK STRUCTURE PROVIDED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2010/133091
Kind Code:
A1
Abstract:
A cylinder lock with double opening angles includes a lock shell (1), a lock core (2), key holes (4, 6) and ball components (7, 8). The key holes (4, 6) are respectively a main key hole (4) and a secondary key hole (6). The ball components (7, 8) are respectively a first ball component (7) and a second ball component (8). The outer periphery surface of the lock core (2) is provided with a step part (21) which is inward depressed towards the center of a circle and extends along the axial direction of the lock core (2). When a main key (3) has been inserted into the main key hole (4), the rotation of the main key (3) can drive the lock core (2) to rotate to the first opening angle until balls (81) of the second ball component (8) are contacted with the step part (21), and when a secondary key (5) is inserted into the secondary key hole (6), the secondary key (5) will drive balls (81) of the second ball component (8) to release the contact between balls (81) and the step part (21), so that the lock core (2) is driven by the simultaneous rotation of the main key (3) and the secondary key (5) to rotate to the second opening angle. A safety lock structure provided with the cylinder lock is also provided.
