PURPOSE: A device for fixing a blackboard frame is provided to increase the aesthetic appearance by making a threaded part invisible, and to facilitate the installation work by introducing screws into longitudinal slots of the fixing device at four corners of the blackboard to pass through the fixing device to then be fixed on a wall in a stable, tightened manner, thereby consequently improving working efficiency and stability. CONSTITUTION: The device for fixing a blackboard frame(100) comprises: an L-shaped body(1) having an opened upper portion and an internal space(11), a connection unit(2) provided at either side thereof, a recess(3) integrally formed at a lower portion of the connection unit(2) to be connected with the frame(100), and a slot(4) having a substantially triangular shape. The frame(100) has an opening(112) connected to a blackboard panel fixedly installed thereon and a cavity(111) connected to the connection unit(2) provided at either side of the fixing device. A tightly fastened structure is established such that the frame(100) is inserted into the recess(3) by a predetermined length and the connection unit(2) of the fixing device is inserted into the cavity(111) of the frame(100).
