Since the upper end of the limit groove extends to the obliquely above the insertion part, the limit piece can rotate upwards to remove the hindrance to the insertion part, so that the insertion part can be moved from The socket enters or moves out, but when moving out, human intervention must be performed, and it will not move out of the socket in a free state.

In the above-mentioned plug-type scaffold fall-off prevention device, a contact portion is formed on the top end of the insertion portion, and the outer side of the contact portion is arc-shaped and adheres to the outer side of the vertical rod. The insertion part fits with the outer side of the vertical rod through the interference part, so as to increase the connection stability of the horizontal rod and the vertical rod.

According to the bolt-type scaffold fall-off prevention device described above, a cross-bar joint is connected to one side of the upper end of the insertion part, and the cross-bar joint is provided with a cross-bar interface. The upper end of the plug joint carries out the assembly of the cross bar through the cross bar joint.

The beneficial effect of the present invention is that: the corrugated buckle extends outward to form a socket part, and the socket part is provided with a socket opening; The slot is connected with the limiting part, the socket part is inserted into the socket part through the socket opening, and the limiting part is used to limit the socket part to escape from the socket opening. The present invention improves the connection mechanism between the cross bar, corrugated buckle and vertical bar, and adds an anti-collapse mechanism, which changes the traditional connection mode between the horizontal bar, corrugated buckle and vertical bar. The connection is stable and flexible, and can Effectively prevent the occurrence of collapsing phenomenon.
