Drop-proof device for latch type scaffold

Abstract

The invention relates to a drop-proof device for a latch type scaffold. A drop-proof mechanism is provided with an edge buckle; the center of the edge buckle is provided with a ventilation opening; the edge buckle is connected with a vertical rod through the ventilation opening; the edge buckle extends outwards to form a socket welding part; the socket welding part is provided with a socket welding hole; the drop-proof mechanism also comprises an insertion part; a limiting groove is formed in the lower end of the insertion part and is connected with a limiting piece; the insertion part is inserted into the socket welding part through the socket welding hole; the insertion part is prevented from being dropped out of the socket welding hole through the limiting piece. The upper part of the insertion part is wide and the lower part of the insertion part is narrow; the width of the lower end of the insertion part is less than that of the socket welding hole; after the insertion part is gradually widened from bottom to top, the width of a middle area of the insertion part is larger than that of the socket welding hole. According to the drop-proof device for the latch type scaffold disclosed by the invention, a connection mechanism arranged among a cross rod, the edge buckle and the vertical rod is improved, and the drop-proof device is additionally arranged, and a conventional connection way among the cross rod, the edge buckle and the vertical rod is changed, so that the connection is stable and flexible, and the dropping phenomenon can be effectively prevented.

Description

technical field [0001] The invention relates to a bolt-type scaffolding anti-falling device, and relates to the technical field of steel pipe scaffolding. Background technique [0002] In the construction industry, the connection of pipe fittings is essential. The wheel buckle scaffold is a new type of in-line steel pipe scaffold with self-locking function. It is produced according to the JGJ231-2010 standard issued by the Ministry of Housing and Urban-Rural Development. The main components are vertical rods and horizontal rods. The performance of steel pipe scaffolding depends to a large extent on the performance of the joints between the vertical rod and the horizontal rod. In the prior art, corrugated buckles are generally used for assembly between the vertical rod and the horizontal rod. The contact area between the plug and the corrugated buckle is small, the connection stability is poor, and it is prone to collapse during use. Contents of the invention [0003] The...
