摘要:
A lock mechanism has a cylindrical housing (11) with an axial bore (15) therethrough, and a key-controlled core (50) rotatable within the bore (15) between locked and unlocked conditions and removable from and installable in the bore (15) in the unlocked condition. The core (50) has a plug (55) at its rear end which is mateably engageable in a socket (40) on the front face of a shifter (30), for rotating the shifter (30) within the bore (15) in response to rotation of the core (50), and thereby operating a latch member (48) coupled to the shifter (30). A radial tab (25) on the housing is receivable in an arcuate groove (45) formed in the outer surface of the shifter (30) for limiting rotation of the shifter (30) to facilitate retention of the shifter (30) in the single rotational orientation upon removal of the core (50) from the housing. An O-ring (33) on the shifter (30) frictionally inhibits rotation thereof.
