The invention relates to the technical field of passenger boarding ladders, in particular to a hidden upper platform operating device of a passenger boarding ladder, which comprises an upper platform front cylindrical surface and an operating assembly, the operating assembly comprises a random stop connecting piece, an operating box, a connecting lock, a limiting piece and a magnetic connecting piece, when the operation box completely shields and covers the containing cavity, the operation box is limited and fixed in the containing cavity of the front cylindrical surface of the upper platform through the connecting lock, at the moment, the operation box is completely hidden in the containing cavity of the cambered surface of the front cylindrical surface of the upper platform, and the operation box is completely hidden in the containing cavity of the cambered surface of the front cylindrical surface of the upper platform. Therefore, the situation that rainwater or snow water gradually intrudes into the upper platform operation device due to the fact that the operation assembly is directly externally installed on the vertical face of the front cylindrical face of the upper platform is avoided, and then the situation that the rainwater or the snow water intruding into the upper platform operation device affects the service life of electrical elements in the device is avoided.
本发明涉及旅客登机梯技术领域,具体涉及一种旅客登机梯隐藏式上平台操作装置,包括上平台前柱面和操作组件,操作组件包括任意停连接件、操作箱、连接锁、限位件和磁性连接件,在不使用操作箱时,转动操作箱,当操作箱将容纳腔室完全遮挡覆盖时,让连接锁将操作箱在上平台前柱面的容纳腔室内进行限位固定,此时操作箱被完全隐藏在上平台前柱面的弧面的容纳腔室内,通过将操作箱被完全隐藏在上平台前柱面的弧面的容纳腔室内,从而避免了操作组件直接外置安装在上平台前柱面立面上会导致雨水或雪水逐渐侵入到上平台操作装置内部,进而避免了侵入到上平台操作装置内的雨水或雪水对装置内的电气元件的使用寿命造成影响。
