The invention relates to the technical field of rail transit, in particular to a telescopic subway handrail hanging bracket which comprises a mounting box, a rotating shaft, a driving motor, a guide sleeve, a first mounting rod and the like. A rotating shaft is rotationally connected into the mounting box, a driving motor is connected to the right side of the mounting box, an output shaft of the driving motor is connected with the rotating shaft, guide sleeves are connected to the left and right parts of the rotating shaft, and a first mounting rod is slidably connected between the left and right guide sleeves. During normal use, a passenger grabs the handle to keep balance, when the handle swings left and right due to inertia, the threaded rod rotates to roll the handle, the passenger is controlled to quickly return to the body shape by pulling the handle upwards, and the inertia of the passenger is relieved; when the device needs to be retracted, the driving motor operates to drive the rotating shaft to rotate, so that the first mounting rod rotates upwards; and through the first contact block and the guide plate, the first mounting rod can contract upwards while rotating upwards, and under the action of cooperation of the square plate and the contact frame, the contact frame rotates to roll the handle.
本发明涉及轨道交通技术领域,尤其涉及一种伸缩式地铁扶手吊架,包括有安装箱、转轴、驱动电机、导套和第一安装杆等;安装箱内转动式连接有转轴,安装箱右侧连接有驱动电机,驱动电机的输出轴与转轴连接,转轴左右两部均连接有导套,左右两个导套之间滑动式连接有第一安装杆。正常使用时,乘客抓握拉手保持平衡,在拉手因惯性左右摆动时,螺纹杆转动能够收卷拉手,通过向上拉动拉手来控制乘客快速回正身形,减缓乘客的惯性,当需要收缩本装置时,驱动电机运作可带动转轴转动,进而使得第一安装杆向上转动,通过第一接触块与导向板可使得第一安装杆在向上转动的同时向上收缩,而在方形板与接触架配合的作用下,接触架转动也会对拉手进行收卷。
