Zusammenfassung:	A slow-closing door hinge, includes a first foldout (1) and a second foldout (2) having a shaft sleeve respectively. A fixed rod (3) is fixedly mounted in the shaft sleeve of the first foldout (1), and a rotating rod (5) is fixedly mounted in the shaft sleeve of the second foldout (2). A connecting rod (4) connects the fixed rod (3) and the rotating rod (5). The connecting rod (4) and the fixed rod (3) are movably connected, and a hollow groove (46) is provided at the joint. A restoring spring (45) in contact with the fixed rod (3) and fixed to the connecting rod (4) is provided in the hollow groove (46). The connecting rod (4) is connected with the rotating rod (5) in a coaxial, rotationally actuating manner. The relative forward and backward rotation of the fixed rod (3) and the rotating rod (5) cooperates with the restoring spring (45) to drive the connecting rod (4) in a reciprocal motion within the shaft sleeve. The slow-closing door hinge has a simple structure, is easy to install, and can avoid the loss of slow-closing function when a malfunction occurs.
