Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of regulating error scope greatly, easy to assembly, time saving and energy saving, is easy to the eccentric bolt captured.
Background technique
In fastener areas, often need to utilize many hinge points to carry out anatomical connectivity, between hinge point, have coaxality requirement.Such as when installing doorframe, due to part manufacture or be equipped with error, cause and there is bias between hinge point and do not meet coaxality requirement, clearance distance between door and doorframe cannot be adjusted, repeated disassembled and assembled is needed to ressemble when installing not in place, waste of manpower, process is loaded down with trivial details.In this case, need to regulate the hinge point of bias, make it meet coaxality requirement.Traditional regulative mode adopts single eccentric bush to realize.Eccentric bush needs to get full pattern at the scene, then carries out following process, and sampling difficulty is large, and accuracy of manufacturing is difficult to ensure.Single eccentric bush can only realize taking reference point as the adjustment on the circular arc of center of circle certain radius length, regulates surplus little.The time-consuming effort of this compensation way, and lining can be caused repeatedly to add work.In addition, if when lining needs to change, need again to rule, locate, cannot once assemble successfully, greatly increase more change jobs time, difficulty and cost.
Model utility content
In order to solve the defect that above-mentioned technology exists, the utility model provides a kind of regulating error scope large, easy to assembly, time saving and energy saving, is easy to the eccentric bolt captured.
The utility model realizes the technological scheme that above-mentioned technique effect adopts:
A kind of eccentric bolt, comprise integrated pad, eccentric circle washer and bolt shank, wherein, described pad is positioned at the exterior edge face of described eccentric circle washer, the diameter of described eccentric circle washer is less than the diameter of described pad, and described pad is coaxial with described eccentric circle washer, described bolt shank and described eccentric circle washer disalignment, described bolt shank is provided with the screw thread matched with nut, and the exterior edge face of described pad is provided with whirlpool screw thread.
Above-mentioned a kind of eccentric bolt, the distal end faces of described bolt shank is provided with recessed to the binding groove in described bolt shank, and the axle center of described binding groove and the axle center of described bolt shank coincide.
Above-mentioned a kind of eccentric bolt, the outer circumferential end face of described bolt shank and the outer circumferential end face of described eccentric circle washer tangent.
Above-mentioned a kind of eccentric bolt, described binding groove is regular polygon binding groove, and the bottom land of described regular polygon binding groove is the arcuate bottom of indent.
Above-mentioned a kind of eccentric bolt, described regular polygon binding groove is regular hexagon binding groove or regular pentagon binding groove.
Above-mentioned a kind of eccentric bolt, the groove depth of described regular polygon binding groove is not less than 1/3rd of described bolt shank length.
Above-mentioned a kind of eccentric bolt, the number of turns of described whirlpool screw thread is no less than 3 circles.
The beneficial effects of the utility model are: the utility model is when for fastening assembling, on eccentric circle washer and hinge, the draw-in groove groove width of strip is suitable, eccentric circle washer is stuck in the draw-in groove on hinge, pad is positioned at hinge one side end face, bolt shank is positioned at hinge opposite side end face, there is alignment error and cause door can not normal rotation when opening in the gap between door and doorframe, bolt shank is made to be partial to different positions by swivel bolt, thus new mounting point can be obtained, make the gap of door and doorframe adjustable, avoid causing door can not normally folding owing to installing error, the problem of repeated disassembled and assembled, reduce user's trouble.The special whirlpool lines of the utility model pad exterior edge face, adds sense of touch and aesthetics, and workman captures convenient when assembling, have fastening effect good, easy to assembly, the feature that use safety coefficient is high.

Embodiment
For making to do further to understand to the utility model, referring to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 4, be a kind of eccentric bolt that the utility model proposes, this bolt comprises integrated pad 1, eccentric circle washer 2 and bolt shank 3.Wherein, improve as one of the present utility model, pad 1 is positioned at the exterior edge face of eccentric circle washer 2, bolt shank 3 and eccentric circle washer 2 disalignment, pad 1 is coaxial with eccentric circle washer 2, and bolt shank 3 is provided with the screw thread 4 matched with nut, the exterior edge face of pad 1 is provided with whirlpool screw thread 6, the number of turns of this whirlpool screw thread 6 is no less than 3 circles, and when corresponding to the pad 1 of different size, the flight pitch between the number of turns of whirlpool screw thread 6 and adjacent whirlpool screw thread can be different.The distal end faces of bolt shank 3 is provided with recessed to the binding groove 5 in bolt shank 3, and the axle center of this binding groove 5 and the axle center of bolt shank 3 coincide.The outer circumferential end face of bolt shank 3 and the outer circumferential end face of eccentric circle washer 2 tangent, when error appears in installation, make bolt shank 3 forward diverse location to by swivel bolt and can obtain new mounting point.As a kind of preferred embodiment of the present utility model, binding groove 5 is preferably regular hexagon binding groove or regular pentagon binding groove, and its bottom land is the arcuate bottom of indent, and the groove depth of binding groove 5 is not less than 1/3rd of the length of bolt shank 3.In assembly process, only need one the open-end wrench of the inner hexagon spanner of 5mm and 17mm can be completed assembling.
