[0002] Authorization announcement number CN220747963U, patent title: Small-angle buffer silent hinge; the utility model relates to the field of hinges, specifically to a small-angle buffer silent hinge, including a base, a hinge fixed to the top of the base by screws, the hinge end is rotatably connected to the four holes of a connecting piece by a rotating pin, the end of the connecting piece away from the hinge is rotatably connected to a pocket, a groove is provided in the middle of the pocket, a damper is fixedly installed at the bottom of the inner wall of the groove, one end of the damper is rotatably connected to the connecting piece, the end of the connecting piece away from the damper is rotatably connected to the hinge end, and the connecting piece is located inside the four holes of the connecting piece. The beneficial effect of the utility model is that one end of the damper can be installed on the connecting piece, and the other end of the damper can be installed in the pocket groove. The connection distance between the connecting piece and the pocket is short, the angle is small, the damping and buffering performance is more superior, and most of the pulling force of closing the door can be unloaded when closing the door;

[0003] The applicant believes that the following technical defects exist: a single damper makes the buffer structure unstable when in use, and the damper is set in the middle position. When the four holes of the connector are folded, they need to avoid the damper, which requires a gap. This easily makes the four holes of the connector too thin. As parts that need to move frequently, the life of the four holes of the connector is shortened, and the supporting force is insufficient, making them prone to deformation.

[0004] Therefore, we invented the double-cylinder small-angle two-stage force hinge. Utility Model Content
