Abstract
A door handle violence protection structure includes a base, and a bottom plate having a rotating block, a door-handle rotating member, a positioning member, upper and lower spring plates, and a spring case arranged on the base. The bottom plate includes a trough portion. The bottom plate and the upper and lower spring plates are arranged in a trough portion. The door-handle rotating member is provided with an axle portion and the axle portion extends through the bottom plate and rotatably combined with the spring case, so that the bottom plate is rotatable by means of the handle rotating member. As such, when locked, the bottom plate forms a blocked state and the upper spring plate forms a resisting and pressing member so that the door handle forms an idle rotation state that allows for idle rotation to a predetermined angle but does not cause any operation of the lockset.
