The invention discloses a rotatable armrest of a cabin door. Therotatable armrest comprises an armrest rod, a first cross rod, a second cross rod, two flange bases and a hinge device, and one ends of the two cross rods are respectively, vertically and fixedly connected with the middle part and the lower part of the armrest rod. The first flange base is fixed to the middle of the inner side face of the cabin door, the second flange base is fixed to the lower end of the inner side face of the cabin door, and the other end of the second cross rod is hinged to the lower portion of the inner side face of the cabin door through a hinge device arranged under the first flange base. Connecting lines of the center of the hinge device and the centers of the two flange bases form an isosceles triangle structure which takes the center of the hinge device as a vertex and the vertex angle is an obtuse angle. The inclination angle of the armrest rod in the inclined state is matched with the inclination angle of the cabin climbing ladder. The rotatable armrest is simple in structure, convenient to machine and low in manufacturing cost. No matter in a vertical state or in a use state, the armrest rod can be reliably locked on the corresponding flange base, so that the problem that the cabin door armrest is high and is difficult to hold when the user goes up and down is solved, and the use safety of the cabin door armrest is improved.
本发明公开了一种舱门可转动扶手,包括扶手杆、第一横杆、第二横杆、2个法兰座和铰接装置,两根横杆一端分别与扶手杆中部和下部垂直固定连接。第一法兰座固定在舱门内侧面中部上,第二法兰座固定在舱门内侧面下端上,第二横杆另一端通过设置在第一法兰座的正下方的铰接装置与舱门内侧面下部铰接,铰接装置中心与2个法兰座中心连线构成以铰接装置中心为顶点且顶角为钝角的等腰三角形结构。倾斜状态扶手杆的倾斜角度与登舱梯倾斜角度匹配。本发明结构简单,加工方便,制造成本低。无论在垂直状态还是使用状态,扶手杆均能可靠地锁定在对应的法兰座上,解决了上下舱时舱门扶手高不易握扶的问题,提高了舱门扶手使用的安全性。
