Embodiment
Below in conjunction with accompanying drawing, the utility model fastening bolt structure is described in further detail.
As shown in Figure 1 to 4, the utility model fastening bolt structure, bolt thread structure is identical with plain bolt worm structure, thread forms adopts part screw thread, the hexagon bolt cap 2 of bolt body 1 head retains, but locating flange 4 is made both sides and is plane structure, dual-side symmetrical position is processed into plane structure inserting surface 6, simultaneously welding or two symmetrical positioning blocks 7 of casting on the close end face of screw thread one side.
Mounting structure is divided into three parts, first portion is through hole 9, through hole 9 is arranged on bearing 8, aperture is according to bolt body 1 aperture design, than bolt body 1 diameter large 1 millimeter～2 millimeters, meanwhile, through hole 9 sides increase by 2 side grooves 10, slot length is quarter turn, the transfer effect that prevents when playing the guiding of bolt body and installing.Second portion is axial restraint groove 13, and axial restraint groove 13 is the gap between bearing 8 and positioning plate 11, and large 0.1 millimeter～0.5 millimeter than the thickness of locating flange 4 of groove width is installed for bolt head on the one hand, plays on the other hand axial restraint effect.Third part is guide channel 12, and guide channel 12 is arranged on positioning plate 11, the form fit of the shape of guide channel 12 and locating flange 4, corresponding with the position of through hole 9, large 1 millimeter～2 millimeters than the width between inserting surface 6 of guide channel 12 road width.Guide channel 12 bottom surfaces are circular arc 3 structures, and it is coaxial with through hole 9, and radius of curvature is greater than 1 millimeter～2 millimeters of 2 external diameters of nuts.
