The present invention relates to an auto-lock device which is installed in a bicycle parking stand in order to prevent theft cases. The auto-lock device comprises: a first frame where an insertion groove is formed in order to partially insert a wheel of a bicycle, and where a perforated latch hole is formed so that a latch can be inserted into the insertion groove; a second frame which is angularly connected with the back side of the first frame; a pressing plate whose one end is connected at the top of the insertion groove, and whose other end is a free end, in order to elastically move; a sensor which is placed at the bottom of the insertion groove in order to generate a signal by being pressed by the pressing plate; a connector which is placed at the bottom of the second frame, and moves in a straight line by being connected with the latch through a link, in order to open or close the latch; and a motor which is placed at the top of the second frame in order to provide a driving force to the connector for a straight-line motion. |
