The invention discloses an anti-falling type externally-hung sliding door system. One side of the top of a door leaf is connected with a first mounting frame, traveling wheels are arranged on the first mounting frame, and the traveling wheels are movably connected with a guide rail groove in one side of a bearing mechanism; a hinge plate is connected to the other side of the top of the door leaf,an anti-falling roller is arranged on the hinge plate, and a gap is formed between the anti-falling roller and an upper pressing strip at the top of the door frame; a lower doorsill is arranged at thebottom of the door frame, a door leaf lower stop is arranged on the side face of the bottom of the door leaf and connected with one end of a lower roller support through a bolt; and a lower roller isarranged at the other end of the lower roller support and movably connected with a groove of the lower doorsill. The anti-falling type externally-hung sliding door system can bear large transverse loading force by limiting disengagement of the door leaf at three positions, when the door leaf is impacted by passengers, the probability that the door leaf is impacted and disengages from the upper guide rail is greatly reduced, and the reliability of the door system is improved.

    本发明公开了一种防脱型外挂移门系统,所述门扇顶部一侧连接有第一安装架,第一安装架上设置有行车轮,行车轮与承载机构一侧的导轨槽移动连接;门扇顶部另一侧连接有铰连板,所述铰连板上设置防脱滚轮,所述防脱滚轮与门框顶部上压条之间设置有间隙;所述门框底部设置有下门槛,所述门扇底部侧面设置有门扇下档,门扇下档通过螺栓与下滚轮支架一端相连接,下滚轮支架另一端设置有下滚轮,下滚轮与下门槛的凹槽移动连接。本发明通过三个位置对门扇脱出的限位,使得门系统能够承受较大的横向加载力,在门扇受到乘客冲击时,极大的降低了门扇受冲击而脱出上导轨的概率,提高了门系统的可靠性。
