A coupling structure for a shaft pin of a hinge is provided to prevent the separation of a shaft pin by coupling connecting pipes of a doorframe fixing plate and a door fixing plate using a shaft pin and coupling a rivet to the top and bottom of the connecting pipe of the doorframe fixing plate and to prevent the relaxation or separation of a rivet from connecting pipes against impact and vibration caused by closing a door while using a hinge. A coupling structure for a shaft pin of a hinge is completed by corresponding connecting pipes(210,310) of a doorframe fixing plate(200) and a door fixing plate(300) of a hinge(100) in a row, inserting a shaft pin(500) into the connecting pipes and inserting a rivet(400) to the top and bottom of the connecting pipe of the doorframe fixing plate. Hereon the shaft pin is composed of a main body(510), coupling bars(520) having screws(520') and inclines(530) connecting the outside diameter of the coupling bar and the outside diameter of the main body; and the rivet is composed of an open pipe(410) projected downward and a spiral(420) formed on the inside of the open pipe to couple with the coupling bars of the shaft pin. |
