Button lock

摘要

In a push button combination lock (1), the lock combination can be set by rotating 180 DEG the desired push button bodies (54). Each push button (10) has a notch (56) in one end of a button body (54) for optionally selecting the set or non-set condition; a lock flange is formed for realizing a locked condition when depressed; upper and lower fan-shaped stopper flanges (60) and (60') are formed on the lower portion of the lock flange with different phases in a 180 peripheral direction; a shank (55') having a square cross section is integrally formed for sliding relative to a slide notch (37) of a key plate (40); a lever handle (7'') can be fixed with a screw (85') relative to a rotation shaft (77) optionally for the right-handed or left-handed operation; and the lever handle (7'') cannot be easily extracted.
