Description
Technical field
The utility model relates to building scaffold, is specifically related to the anti-slip rotary buckle of a kind of steel pipe scaffold.
Background technology
Rotary buckle is the connector of steel tube generally adopting in steel pipe scaffold.At present, conventional rotary buckle adopts rivet shaft to connect Button Block and buckle closure, or by the T shape connector that is arranged on buckle closure one end medium position and the cooperation that is arranged on the T shape connector patchhole of Button Block one end, realize being connected of buckle closure and Button Block, by cambered surface outside the Button Block arranging, realize Button Block and coordinate with holding of steel pipe.The problem of its existence is: the rivet shaft syndeton of Button Block and buckle closure is complicated, is not easy to processing, and particularly, for stamping forming Button Block and buckle closure, cost of production is high; Buckle closure connects by T shape connector, the poor stability of its connection, and buckle closure shaking amplitude is large, causes the stable connection performance of fastener and steel pipe to reduce; While holding steel pipe by cambered surface outside Button Block, cambered surface is generally a line along steel pipe axis with the cooperation of steel tube surface and contacts outside its Button Block, causes fastener to connect skid resistance not enough, easily produce loosening, thereby the potential safety hazard of bringing.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of steel pipe scaffold anti-slip rotary buckle, and this fastener structures is simple, is convenient to processing, and cost of production is low, and the anti-anticreep performance of fastener is good, safe and reliable.
The technical scheme that realizes above-mentioned purpose is: the anti-slip rotary buckle of a kind of steel pipe scaffold, include Button Block, lower Button Block and respectively with upper Button Block, the upper buckle closure of lower Button Block configuration, lower buckle closure, described upper Button Block and lower Button Block are hinged by center rivet, one end of described upper Button Block and lower Button Block is respectively equipped with bolt mounting hole, one end of described upper buckle closure and lower buckle closure is respectively arranged with bolt and installs mouth, upper buckle closure connects tommyhead bolt and is assemblied in described upper Button Block bolt mounting hole, lower buckle closure connects tommyhead bolt and is assemblied in described lower Button Block bolt mounting hole, the other end of described upper Button Block and lower Button Block is respectively provided with a pair of buckle closure connecting hole, the other end of described upper buckle closure and lower buckle closure respectively arranges a pair of buckle closure and is connected gudgeon, described buckle closure connects gudgeon and inserts the upper buckle closure of realization and upper Button Block in described buckle closure connecting hole, being hinged of lower buckle closure and lower Button Block, in the outside cambered surface of Button Block and lower Button Block, respectively arrange on described two pairs with held the protrusion arc surface that steel tube surface coordinates, two pairs protrude the top that arc surfaces lay respectively at cambered surface outside Button Block, and are symmetrical arranged along its outside cambered surface center line.
Further, described buckle closure connects gudgeon and the moulding of buckle closure integrated punching.
Further, described protrusion arc surface and the moulding of Button Block integrated punching.
The beneficial effects of the utility model are:
1, upper and lower buckle closure adopts binaural axis structure and upper and lower Button Block to be hinged, and the stable connection performance of its upper and lower buckle closure and upper and lower Button Block is good, and syndeton is simple, be convenient to one time punching molded, thereby effectively reduce fastener cost of production, enhance productivity.
2, by being arranged on outside Button Block two couple in cambered surface, protruding arc surface and held steel tube surface with quilt and coordinate, strengthened the skid resistance that fastener is connected with steel pipe, improved the safety and reliability energy of fastener.
