Abstract
A kind of hexagon head assembling bolt, the screw rod comprise bolt head, being connected with bolt head, described screw surface is provided with screw thread, described screw rod is provided with transition part between screw thread and bolt head, screw rod is arranged with the pad that can slidably reciprocate along transition part at transition part place, the longitudinal section of described pad is arc, and the bending direction of pad is towards screw thread; The longitudinal section of pad of the present utility model is arc, and the bending direction of pad is towards the screw thread on screw rod, makes pad can compressing component well, enhances compression effect and the fastening effect of bolt.
Description
Technical field
The utility model relates to a kind of bolt, and particularly a kind of hexagon head assembling bolt, belongs to technical field of fastening.
Background technique
Bolt has bolt head and a screw rod class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format is called that bolt connects.If nut is screwed off from bolt, can make again part separately, therefore bolt connect to belong to and removably connect.
In fastener areas, band pad assembling bolt is one of conventional fastening piece, the band pad assembling bolt used in the market, steering capability is poor, and the compression effect of pad is not good yet, particularly when connection, pad easily loosens, and causes fastening effect greatly to decline.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, the utility model provide a kind of guidance quality good, compress effect and the good hexagon head assembling bolt of fastening effect.
The utility model solves the technological scheme that its technical problem adopts: a kind of hexagon head assembling bolt, the screw rod comprise bolt head, being connected with bolt head, described screw surface is provided with screw thread, described screw rod is provided with transition part between screw thread and bolt head, screw rod is arranged with the pad that can slidably reciprocate along transition part at transition part place, the longitudinal section of described pad is arc, and the bending direction of pad is towards screw thread.
As preferably, described bolt head is being provided with step with transition part connecting place, and the diameter of step is less than the diameter of bolt head.
As preferably, the joint of described step and transition part is curved-surface structure.
As preferably, described screw rod is provided with guiding polished rod in the one end away from bolt head, and the diameter of guiding polished rod is less than the diameter of screw rod, and the joint of guiding polished rod and screw rod is provided with 30 ° of inclined-planes.
As preferably, described guiding polished rod is provided with arc angling away from the periphery of screw rod one end end face.
As preferably, described bolt head, screw rod, transition part and guiding polished rod are formed in one.
The beneficial effects of the utility model are: bolt head is being provided with step with transition part connecting place, and the longitudinal section of pad is arc, and the bending direction of pad is towards the screw thread on screw rod, make pad can compressing component well, enhance compression effect and the fastening effect of bolt; Screw rod is provided with guiding polished rod in the one end away from bolt head, and the joint of guiding polished rod and screw rod is provided with 30 ° of inclined-planes, enhances the guidance quality of bolt.
