Double-hook hammered connecting mechanism for steel pipe scaffolds and hammered fastener comprising same
The invention discloses a double-hook hammered connecting mechanism for steel pipe scaffolds and a hammered fastener comprising same. The hammered fastener comprises a base mold, top cover molds, movable hooks and hammered shafts. One end of each top cover mold is rotatably articulated with one end of the base mold through a flush bolt, the other end of the base mold is articulated with one end of each movable hook through one hammered shaft, the other ends of the top cover molds are fastened with the other ends of the movable hooks through fastening structures, each hammered shaft is of a three-section stepped shaft structure, the middle shaft is a crankshaft, the diameters of the two side shafts are equal, and the diameter of the middle shaft is less than the diameters of the two side shafts; a steel pipe is fixed between the base mold, the top cover molds and the movable hooks, and the hammered shafts pass through the through holes of the base mold and the movable hooks. The hammered fastener adopts structures such as a rotatable hook, double-hook locking, hammered shaft and double-cover-fastened double-pipe connection mode, dispenses with the bolt-nut screwing mode of old fasteners, and rejects the single-cover-fastened double-pipe connection mode of old fasteners. Compared with conventional fasteners, the hammered fastener is characterized in that the hammered fastener is quick to mount and demount and easy to operate and is convenient, labor-saving, safe and reliable.
