LOCK MECHANISM WITH STATE INDICATION FUNCTION
A lock mechanism with state indication function includes a housing (1), a cap (2) and an indicator (3). The indicator (3) includes active and passive indicators (3a, 3b) arranged circumferentially around a central axis (21). The active indicator (3a) includes a cam matching surface (3a-1) extending circumferentially around the central axis (21) and a stopping end (3a-2) located at an end of the cam matching surface (3a-1) corresponding to the pivoting center of the active indicator (3a). A radial convex portion (22) of the cap (2) slides along the cam matching surface (3a-1) to make the active indicator (3a) rotate away from the central axis (21). The radial convex portion (22) pushes the stopping end (3a-2) of the active indicator (3a) to make the active indicator (3a) rotate to a recovery position in which an indicating portion (31) of the indicator (3) is covered by the cap (2). The passive indicator (3b) is in linkage connection with the active indicator (3a) through a gear transmission device, making the passive indicator (3b) be unfolded and folded synchronously along with the active indicator (3a).
