The invention discloses a telescopic step missing prevention threshold device convenient to disassemble and assemble, and relates to the technical field of thresholds. The telescopic step missing prevention threshold device comprises a threshold body; the bottom of the threshold body is connected with a foundation, a connecting block is installed on one side of the threshold body, electric push rods are installed on one side of the interior of the threshold body, and one end of each electric push rod is connected with a baffle; a limiting block is installed at the top of the baffle, hook-and-loop fasteners are installed at the top of the baffle, and a non-slip mat is bonded to the tops of the hook-and-loop fasteners. According to the invention, the multiple electric push rods are installedin the threshold body and can push the baffle, so that the baffle stretches out and draws back, the gap between the foundation and a subway is blocked, people are prevented from missing steps, and the people are protected; the bottom of the battle is connected with a rotating rod in an abutting manner and when the baffle stretches out and draw back, the rotating rod at the bottom can be driven torotate through a rotary disc, so that noise generated by friction between the baffle and the threshold body is avoided.

    本发明公开了一种便于拆卸组装的伸缩型防踏空门槛装置,涉及门槛技术领域,包括门槛本体,所述门槛本体的底部连接有地基,且门槛本体的一侧安装有连接块,所述门槛本体的内部一侧安装有电动推杆,且电动推杆的一端连接有挡板,所述挡板的顶部安装有限位块,且挡板的顶部安装有粘扣带,所述粘扣带的顶部粘接有防滑垫。本发明中,本产品在门槛本体的内部安装有多个电动推杆,电动推杆可以推动挡板,使得挡板进行伸缩,将地基与地铁之间的缝隙挡住,防止人员踩空,对人员进行保护,且挡板的底部抵接有转杆,挡板进行伸缩时,可以带动底部的转杆通过转盘进行旋转,从而避免挡板与门槛本体因为摩擦而发出的噪音。
