The present invention relates to an automatic locking device. Looking characteristic of compositions over, the automatic locking device comprises: a locking loop (2) installed at doors and windows (1) and a locking body (100) locked at the locking loop (2). A handle (12) is installed inside the locking body (100). The locking loop (2) comprises a locker (10) to lock or release the locking loop (2); a stopper (20) to maintain a release state by being interlocked at a position in which the locker (10) is released and to be separated with the locker (10) by a control of a lever (22); and a sensing piece (30) bounced with a finger at the locking body (100), transferred to an inside and an outside of the locking body (100) by being touched at the locking loop (2), and to separate the stopper (20) interlocked with the locker (10) when the sensing piece is transferred to the outside. Therefore, the present invention has effects for maintaining a release state of the locker by the stopper, for automatically activating a locking state of the locker by releasing the stopper with the sensing piece in opening a door, provides convenience capable of locking the door without a special control of the user when the user close the door after opening the door, and for improving a structure as a malfunction prevention structure and compact size structure by simplifying an operating structure. |
