Abstract

A set bar mechanism comprises a set bar (2), a set of press-fit components and a push-pull mechanism corresponding to the press-fit components. A containing cavity (21) is formed in the set bar (2). The press-fit components are arranged in the containing cavity (21) and synchronously move in the direction perpendicular to a lock shell panel along with the movement of the set bar (2). The push-pull mechanism is arranged between a lock shell (1) and the press-fit components and drives the press-fit components to extend out of or retract into the containing cavity (21) in the movement direction of a door leaf when the set bar moves in the direction perpendicular to the lock shell panel. The press-fit components are closely attached to the side edge of a slot hole of a set bar slot when the set bar enters the set bar slot. The set bar mechanism is low in noise and high in safety.
