This invention relates to the field of building door and window technology, and in particular to an outward-opening built-in hinge suitable for wide-cavity profiles. The hinge includes a base plate, a load-bearing rod, a linkage rod, a sliding rod, a first support plate, a second support plate, and a slider. The base plate has a guide groove, in which the slider is placed. One end of the sliding rod is connected to the slider by a rivet. One end of the load-bearing rod and the linkage rod are fixed to the base plate by rivets. A second support plate is stacked on top of the first support plate, with both ends of the second support plate riveted to the load-bearing rod and the linkage rod, respectively. The other end of the sliding rod is riveted to the middle of the linkage rod. This invention has a simple structure, is easy to adjust, and has a strong load-bearing capacity, making it suitable for outward-opening windows with built-in hinges in various wide-cavity profiles.
