CN2418209Y - Locking device for handle door-lock - Google Patents

Abstract

The utility model relates to a locking device for a handle door-lock, which is characterized in that a driving semi-gear with a special-shaped through hole is offset and overlapped on an inclined tongue shifting slice and is tensed by a restoring spring, and the special-shaped through hole is simultaneously internally sheathed with a multi-angle square stem casing; the driving semi-gear is engaged with a driven semi-gear, wherein, one end of which is hinged with a pusher dog which is positioned by a torsional spring, and an edge on the other side of a pushing slice is provided with pushing teeth which are matched with the pusher dog; the driving semi-gear and the pushing slice are simultaneously connected with a misoperation preventing safety mechanism. The technology of the utility model overcomes the defect that an ordinary locking device for a handle door-lock can be back locked only through a key and the process is complicated, and the utility model can be directly back locked through a handle outside a door. The utility model has the advantages of convenient and rapid operation and strong misoperation preventing performance.
