Concealed hinge

The utility model relates to a concealed hinge, which comprises a hinge mount provided with an installing hole, and a hinge body, wherein, the middle part of the hinge mount is folded up in a star shape; the hinge body is inserted in a cavity formed by the star-shaped folding-up position of the hinge mount and is movably connected with the hinge mount through a rotating shaft which is arranged on the star-shaped folding-up position, and the side face of the hinge body approximately forms a 7 shape. The hinge body of the utility model is concealed in a tabletop so as to avoid an exerted hinge having inconvenient use, and meanwhile, because the middle part of the hinge mount is folded up in the star shape, screws can be installed on the bottom surface of the tabletop so as to be not easy to loosen and desquamate.
