Scaffold anti-falling self-locking connecting piece

Abstract

The utility model relates to the technical field of scaffold, disclose a scaffold anti -falling self -lock connecting piece, including vertical tube, the vertical tube outside fixedly connected with fastener, two pipe heads are fixedly connected in fastener, the movable joint is limited to the post in pipe head, a plurality of first connecting plates are fixedly connected to one side of limited post, and the side fixedly connected with the limiting block of first connecting plate away from limited post, and a plurality of first connecting plates between movable joint have connecting block. The vertical tube outside sets fastener, and fastener two ends respectively set up a pipe head, and the telescopic limiting post is set up in the pipe head, and the telescopic shift block and the clamping block are set up outside the limiting post, when replacing and the pipe head connection, can make the pipe head utilize the slope surface of one end of limiting post and push the limiting post into the pipe head, when the cross pipe and the pipe head port alignment, can make the limiting post insert into the cross pipe with the first compression spring force, and cooperate the clamping block and realize the quick assembly of pipe head and cross pipe.
