An embodiment of the present invention provides a door stopper device which restricts the movement of a door by being installed on the lower end of the door, the door stopper device comprising: a fixing plate which is fixed on the lower end of a door, which has a pair of guide members on the front thereof and a first elastic member mounting unit, on which a first elastic member is mounted in between the guide members, provided thereon; a sliding guidance unit which is positioned on the lower part of the first elastic member and which has a saw-toothed groove with a saw tooth shape formed on the front thereof; a sliding unit which has a sliding saw-toothed unit, which is interlocked with the saw-toothed groove, provided on the inner surface thereof and which vertically moves by being interlocked with the first elastic member elastically moved by an external force by being connected to the sliding guidance unit; a stopper unit which is installed on the lower part of the sliding unit and which comes in contact with the bottom surface when the sliding unit is moved down by an external force, which uses a friction force with the bottom surface to restrict the movement of the door, and which is released from a contact state with the bottom surface when the sliding unit is moved up by an elastic force of the first elastic member; a housing cover which is connected to the fixing plate to wrap around the sliding unit; and a stopper which passes through the housing cover and the sliding unit to be connected to the sliding guidance unit and which releases a contact state between the sliding guidance unit and the sliding unit by pressing the sliding guidance unit when an external force is applied to the first elastic member. |
