The invention belongs to the technical field of airplane cabin door mechanism design, and particularly relates to an airplane cabin door clamping stagnation prevention centering guide roller mechanism which is installed on side frames on the two sides of an airplane cabin door connecting edge. Comprising a roller support fixed on the aircraft cabin door, a guide joint fixed on a door frame, a mounting shaft mounted on the roller support, a bushing sleeved on the mounting shaft in a clearance manner, a roller rotatably mounted on the bushing, and a spring sleeved on the mounting shaft to keep the bushing at the initial axial position of the mounting shaft. According to the clamping stagnation prevention centering guide roller mechanism, in the opening or closing process of the cabin door, swinging of the cabin door is limited, clamping stagnation is eliminated, and it is guaranteed that the cabin door smoothly moves according to a preset track.

    本申请属于飞机舱门机构设计技术领域,特别涉及一种飞机舱门防卡滞对中导向滚轮机构,所述滚轮机构安装在飞机舱门连接边两侧的侧边框上,包括:固定在飞机舱门上的滚轮支座、固定在门框上的导向接头、安装在滚轮支座上的安装轴、间隙套在安装轴上的衬套,可旋转安装在衬套上的滚轮,套设在安装轴上使衬套保持在安装轴初始轴向位置处的弹簧,当飞机舱门开或者关闭时,滚轮相对导向接头具有的平面滚动,该防卡滞对中导向滚轮机构,在舱门打开或关闭过程中,限制了舱门摆动,消除了卡滞,保证舱门按照预定轨迹顺利运动。
