LOCKING MODULE OF WIRE AUTO-WINDING DEVICE

摘要

The present invention relates to a locking module of a wire auto-winding device which has improved performance by virtue of an improved wire unlocking structure. The device of the present invention is configured of: a first case having a coupling projection formed thereon; a rotating piece inserted over the coupling projection of the first case in order to be rotated clockwise or counterclockwise; a button member coupled to the rotating piece and being slid in a first direction to rotate the rotating piece by means of a button operation; a stopper member coupled to the rotating piece to be slid in a second direction by means of the rotation of the rotating piece; a resilient spring for pushing and returning one of the button member or the stopper member in the opposite direction; and a second case fastened to the first case to form a component receiving space therein. According to the present invention, as an effect a cam or pinion and a combination of same can be used in the coupling between a stopper and a button so as to freely design operating distance, misalignment can be prevented to suppress malfunctioning, and the movement of a button or noise can be minimized when a wire is withdrawn. In addition, according to the present invention, the advantages are provided in that the shape of a pinion can be altered in order to change an unlocking stroke and a button stroke and form a slim button structure.
