Abstract

The invention relates to a spacing device of shift door lock, comprising lock shell, dialing wheel fixed in the lock shell and locating plate. The dialing arm is set at the side of dialing wheel and a fork is set at the side of locating plate. The invention also comprises three rings of special-shape spring. The head end of special-shape spring is fixed on the dialing arm and the tail end is fixed on the lock shell. The dialing arm extends into the fork to form the dialing connection. Other mechanism matched with the spacing device of shift door lock also comprises lock tongue accommodated in the lock shell and locating shaft for lock tongue. The top of lock tongue can be fixed on the locating shaft in rotation. A boss is set in the middle of lock tongue and inserts into the hole set in the locating plate to form the swinging-arm mechanism. Two long-strip sliding groove ports are set in the middle of locating plate and by two long-strip sliding groove the locating plate can be mated on the locating shaft of lock tongue and the spring guiding shaft in slide so that the locating plate slides along the track limited by said locating shaft of spring and said locating shaft of lock tongue. The invention can be applied in shift door lock needed in various shift doors.
