Suspended graded adjusting hinge mechanism

The invention discloses a suspended graded adjusting hinge mechanism which comprises a supporting framework, a tooth disc I, a tooth disc II and an armrest framework. The tooth disc I is assembled inthe supporting framework. The tooth disc II is assembled in the armrest framework. The tooth disc I and the tooth disc II are engaged. The armrest framework rotates to drive the tooth disc II to rotate. The clockwise rotation force of the tooth disc II is larger than the anticlockwise rotation force. The suspended graded adjusting hinge mechanism is assembled in an armrest, the seat armrest can beadjusted at multiple angles to meet the requirement for the use comfort level of a client, parts are less, the structure is simple, and manufacturing cost is reduced. 本发明公开了种可悬停的分级调节铰链机构，包括支撑骨架、齿盘Ⅰ、齿盘Ⅱ和扶手骨架，齿盘Ⅰ装配在支撑骨架内，齿盘Ⅱ装配在扶手骨架内，齿盘Ⅰ和齿盘Ⅱ啮合，扶手骨架转动能够带动齿盘Ⅱ转动，齿盘Ⅱ顺时针转动力大于逆时针转动的力。本发明装配在扶手内，能够让座椅扶手可多角度调节，以达到客户使用的舒适度要求，而且零部件少，结构简单，降低了造价成本。
