Description
Technical field
The utility model relates to a kind of bolt.
Background technique
Bolt: by head and screw rod (having an externally threaded cylindrical body) class fastening piece dimerous, need to cooperate with nut, be used for being fastenedly connected two parts that have through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make these two parts separately again, be to belong to removably connect so bolt connects.The bolt that is generally used at present during as circular arc type, understands that hole wall is damaged at hole wall after screwing, influence using effect.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of and hole wall is the close-fitting bolt of hole energy of circular arc type.
For solving above technical problem, the utility model is realized by the following technical solutions: a kind of bolt, comprise bolt head and bolt shank, described bolt head end face offers groove, and the side is arc surface, and the cross section of bolt head is isosceles trapezoid, described arc surface is arranged on the bi-side of isosceles trapezoid, offer screw thread on the described bolt shank shaft, described bolt head and bolt shank connect into an integral body, are provided with arc-shaped transition at bolt head and bolt shank joint.
Further, described groove is that groove operated in hexagon or square or cross.
Further, described arc surface is outer convex arc surface.
Further, described arc is the indent arc.
The beneficial effects of the utility model are: when the hole inwall was the occasion of circular arc type, this bolt can match with inwall closely, can not damage inwall, in use was difficult for becoming flexible, and is safe and reliable, the better effects if of use.
