Door hinge having buffering function
Disclosed is a door hinge having a buffering function, comprising a casing (1), a hinge cup (10), a linking member A (5) and a connecting member B (8), wherein a damper (3) is disposed within the casing (1) in an axially movable manner, and an end portion of a piston rod at the front end of the damper (3) is fixedly connected to the casing (1). The right end of the linking member A (5) is rotatably disposed inside the casing (1) via a first rotating shaft (4), while the left end of the linking member A (5) is rotatably connected to the hinge cup (10) via a third rotating shaft. The right end of the connecting member B (8) is rotatably disposed inside the casing (1) via a second rotating shaft (7), while the left end of the connecting member B (8) is rotatably connected to the hinge cup (10) via a fourth rotating shaft. The end portion at the right end of the linking member A (5) or the connecting member B (8) is disposed corresponding to the rear end of the damper (3). The moving direction of the damper (3) is same as that of the linking member A (5) or the connecting member B (8), which greatly extends the stroke of the linking member A (5) or the connecting member B (8), thus achieving a better technical effect of buffering.
