Abstract

The anti-falling track comprises a sub-track, a connecting plate and a fastener, wherein the sub-track is provided with a horizontal plate and a vertical plate, one end of the vertical plate is connected with the horizontal plate, the end part of a first sub-track is linearly close to the end part of a second sub-track, wavy bumps extend into wavy interfaces, the connecting plate is provided with a plurality of connecting holes which are linearly arranged along the length direction, the connecting plate is in planar contact with the vertical plates of the first sub-track and the second sub-track, the connecting plate extends from the end part of the first sub-track to the end part of the second sub-track, and after penetrating through the connecting holes and the vertical plate holes, a fixing bolt is matched with a fixing nut to fix the first sub-track, the second sub-track and the connecting plates on two sides into a whole, so that the first sub-track and the second sub-track are linearly aligned. The staggered connection of the wavy convex blocks and the wavy interfaces can avoid the phenomenon that the falling protector blocks when sliding through the butt joint position of the track to cause blocking.
