A fall prevention device for the gap between the platforms and rail carriage doors supporting rod assembly consists of interior rod and exterior rod. There is a space reserved in the vertical direction between the two rods to facilitate the smooth sliding of the rod. A position limit is fitted to the back end of the interior rod. A groove is cut out on the exterior rod along the sliding direction to allow the position limit to slide with the interior rod. The maximum extraction position is set on the exterior rod. A compressed spring is installed at the end of the rod assembly. A Spring Leaf is positioned at the top of the back end of interior rod, which maintains the horizontal position of the interior rod when there is no external force applied. During the opening and closing of the carriage door, the stopper board on the carriage door will force the protection board to contract under the carriage floor and press the interior rod to contraction position.
