Title:
緩衝機能付きドア用蝶番
Document Type and Number:
Japanese Patent JP6875563
Kind Code:
B2
Abstract:
Disclosed is a door hinge having a buffering function, including: a casing (1) within which a damper (3) is disposed in an axially movable manner, an end portion of a piston rod at the front end of the damper (3) being fixedly connected to the casing (1); a hinge cup (10); a linking member A (5) with a right end rotatably disposed inside the casing (1) via a first rotating shaft (4) and a left end rotatably connected to the hinge cup (10) via a third rotating shaft; and a connecting member B (8) with a right end rotatably disposed inside the casing (1) via a second rotating shaft (7) and a left end 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 (8). 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.
