LEVER FOR DOOR LOCK

摘要

PURPOSE: A lever for door lock is provided to allow door lock to be easily installed regardless of the thickness of door by smoothly adjusting the screw tube and flange, while achieving an aesthetic enhancement of the flange. CONSTITUTION: An adjustment screw tube having, at a rear end thereof, a stepped portion(9a), at an outer periphery thereof, a screw portion(9b), and at a front end thereof, an extended fixing piece(9c), is assembled to a central screw tube of a flange constituting a lever assembly. The adjustment screw tube has a bent protrusion(9d) formed at the front end of the adjustment screw tube, and an end(9f) formed at the interior of a hole(9e). An operation ring having an aperture and a stopper protrusion(10a), an elastic spring having outer bent pieces(12a,12b), and a stopper ring(11) having a guide(11a), a stopper protrusion and a recess(11c) are sequentially inserted into the hole of the adjustment screw tube, such that the guide and the stopper protrusion of the stop ring get caught at the bent protrusion of the adjustment screw tube. A spindle penetrates through the center of the adjustment screw tube, and the stopper protrusion of the operation ring gets caught at a groove formed at the spindle. The spindle has a protrusion engaged with the recess of the stop ring.
