The present invention relates to a coupling structure for a three-dimensional door for a sink. The present invention forms the door into a prefabricated type, and allows a central panel to protrude higher than side panels, thereby allowing a user to conveniently assemble the door and improving the beauty of the door. The door consists of the central panel, an upper and a lower panel, and a left and a right panel. Each of four sides of the rectangular central panel comprises a first protrusive surface, a second protrusive surface, and one insertion groove. Each of the rectangular upper and lower panels has sides comprising a first protrusive surface, a second protrusive surface, a third protrusive surface, and one insertion grooves, and each of both sides of the upper and lower panels has one protrusive surface. Each of the rectangular left and right panels has sides comprising a first protrusive surface, a second protrusive surface, a third protrusive surface, and one insertion grooves. The present invention provides the door which is not two-dimensional but three-dimensional, quickly manufactures the door with a prefabricated method in all manufacturing processes, and surely provides a three-dimensional effect for the door. |
