LOCK MECHANISM

摘要

An improved security lock mechanism (100, 200, 400) is provided utilising a blocking member (192) to protect a cam lever (174). Furthermore, a lock barrel (116, 416) is engaged to a first lock actuator housing (114, 414) via a pin instead of a circlip. In addition, a cam(106) is provided whose shaft (172)extends from a lock housing (10). A cam (216) is provided with a radially extending member (302) to bear against the surface of alock casing (10). A thumb turn bolt (300) is provided which can be actuated upon axial movement. A cam (406) can be axially retained against a lock barrel (416)upon actuation of a clutch to a security position.
