PURPOSE: A linking structure of water purifier drain pipe is provided to reduce the material cost as the linking structure is simple and economically do the linking task as the linking task of water purifier drain pipe is a simple task of combining the bolt to the nut. CONSTITUTION: The linking structure of water purifier drain pipe comprises a cylindrical bolt (10), a rubber packing (20), and a cylindrical nut (30) which screw-coupled to the cylindrical bolt. The inner surface of the cylindrical bolt is attached and fixed to one side of the outer circumference of the connection pipe of water purifier drain pipe (13) which formed on the connector. The rubber packing is coupled to the inner side of the projection part (10a) of the cylindrical bolt. The water purifier drain pipe inserted in the center hole of the rubber packing through the center hole of the cylindrical nut is seal-coupled to the connection pipe of water purifier drain pipe.
