The invention provides an anti-falling device for a C-shaped steel guide rail. The anti-falling device comprises a main body, a movable body, a hinge seat and a locking part. The main body comprises a first fixed part and a second fixed part, the movable body comprises a movable part and a trigger part, the movable part can horizontally move towards the direction of the second fixed part, the locking part is provided with a first movable end and a second movable end, the first movable end is located in the cavity groove, the second movable end is located in the first interval, and the locking part can move along with the movable part. Meanwhile, the second movable end is screwed into the cavity groove, the first movable end is screwed into the first interval, the guide rail moves in the plumb line direction, and the flanging is located in the first interval and the second interval. When the guide rail falls down, the trigger part can move in the direction away from the movable part through friction force and downward impact force, so that the first movable end is driven to be screwed into the first interval and abut against the second fixed part, the turned edge of the guide rail is fixedly clamped between the first movable end and the second fixed part, and the purpose of preventing the guide rail from falling down is achieved.
本发明提出了一种用于C型钢导轨的防坠装置，包括主体、活动体、铰接座和锁定部件；主体包括第一固定部和第二固定部，活动体包括活动部和触发部，活动部能够朝第二固定部的方向水平移动，锁定部件具有第一活动端和第二活动端，第一活动端位于腔槽内且第二活动端位于第一间隔内，锁定部件能够随活动部移动，同时使第二活动端旋入腔槽内且第一活动端旋入第一间隔内，导轨沿铅垂线方向移动，且翻边位于第一间隔与第二间隔内；通过摩擦力与向下冲击力会造成触发部向远离活动部的方向移动，从而驱使第一活动端旋入第一间隔内并抵近第二固定部，从而将导轨的翻边固定夹持于第一活动端和第二固定部之间，实现了防止导轨坠落的目的。
