Abstract
The utility model relates to the technical field of a rotary fastener for steel tube connection. The rotary fastener comprises a rotary seat and a cover plate, and is characterized in that the rotary seat includes a left rotary seat and a right rotary seat which are mutually connected, the cover plate includes a left cover plate and a right cover plate, the left rotary seat is correspondingly connected with the left cover plate, the right rotary seat is correspondingly connected with the right cover plate, and the inner lateral surfaces, used for contacting with a part to be fastened, of the left cover plate and the right cover plate are of a projecting anti-skid structure. By improving the structures of the inner lateral surfaces, used for contacting with the part to be fastened, of the cover plate and by additionally arranging reinforcing edge ribs at the edge positions of the cover plate, the rotary fastener enhances rigidity and strength of the cover plate, simultaneously increases frictional force to the fastened part, is reliable in fastening and not easy to loose, and effectively saves manufacturing raw materials and reduces manufacturing cost as connecting surfaces of the rotary seat adopt special arc-shaped structures or planer structures.
Description
Technical field
The utility model relates to and is used for the rotary buckle technical field that steel pipe connects.
Background technique
In the prior art, steel pipe rotary buckle commonly used is general to adopt common foundry goods, by the bolt on it enclosing cover of rotary buckle is carried out fastening, thereby reach the purpose that steel pipe is clamped.Because the enclosing cover and the steel pipe of rotary buckle need Long contact time, so be easy to produce loosening and slip, sometimes because the bolt clamping force is excessive, also can cause the enclosing cover distortion of rotary buckle, thereby cause the loosening of steel pipe or come off, bring very big inconvenience to use, sometimes even can cause bad accident.The rotary seat volume of existing common rotary buckle is generally bigger, has so just increased raw-material use, thereby has increased fabricating cost.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art that a kind of rotary buckle is provided, thereby effectively solve problems of the prior art.
For achieving the above object, the technological scheme that the present invention takes is: described a kind of rotary buckle, include rotary seat and cover plate, its characteristics are: described rotary seat comprises interconnective left-handed swivel base and dextrorotation swivel base, cover plate comprises left cover and right cover plate, left-handed swivel base is corresponding with left cover to link to each other, and the dextrorotation swivel base is corresponding with right cover plate to link to each other, and described left cover is the anti-skid structure of convex type with the inner side surface that right cover plate is used for contacting with fastener.
Described left cover and right side edge thereof place are provided with and reinforce the limit muscle.The anti-skid structure of the convex type of described left cover and right cover plate be anti-skidding line.
Described left-handed swivel base is an arcuate structure with the inner side surface that the dextrorotation swivel base contacts with fastener, the middle part of arcuate structure is provided with and is used to the riveting axle mounting hole of realizing that left-handed swivel base and dextrorotation swivel base rotate mutually, the outer side surface of described left-handed swivel base and dextrorotation swivel base also is an arcuate structure, has effectively saved rapidoprint.
The beneficial effects of the utility model are: described a kind of rotary buckle, it is by the architecture advances of the inner side surface that cover plate is used for contact with fastener, and be provided with in the edge of cover plate and reinforce the limit muscle, increased the rigidity and the intensity of cover plate, increased the frictional force to fastening piece simultaneously, it is fastening reliable, be difficult for loosening, the rotary seat junction surface adopts special arcuate structure and plane structure has been saved the making raw material effectively, has reduced fabricating cost.
