<p>The present invention relates to a hinge for the emergency exit of a fireproof shutter, wherein the hinge comprises: a left plate (110) having inner rotary shafts (112) formed at the upper and the lower side of one side thereof, wherein the inner rotary shafts (112) are bent into circular shapes; and a right plate (120) having an outer rotary shaft (122) into which the inner rotary shafts (112) are inserted, wherein the outer rotary shaft (122) has a connection blocking unit (124) formed at the upper side thereof and protruding upwards and has a connection guide groove (125) formed at the lower side thereof so that the connection blocking unit (124) and the connection guide groove (125) touch in a vertical direction and correspond to each other. Therefore, the assembling work of the hinge is completed by blocking a path inside the connection blocking unit after inserting the inner rotary shaft of the left plate into the outer rotary shaft of the right plate to enable mass production by the simple and quick assembling work. In addition, a vertical blocking piece and a central blocking piece are formed at the left plate, the connection blocking unit at the upper side of the left plate is fit and overlapped with a connection guide groove at the lower side of the left plate, and a blocking piece is formed at the center of the outer rotary shaft so that flames are completely blocked.</p> |
