For achieving the above object, the utility model provides following technological scheme: a kind of coiled hair band grommet screw, comprise screw body and pad, screw body comprises screw head and screw rod, and screw head is fixedly connected on one end of screw rod, pad is socketed in screw head and screw rod joint, pad is obliquely installed by inner ring is angled to outer ring, and true dip direction is towards screw rod side, and pad angle of inclination is set to 3 ° to 5 °, with some build joints on pad, build joint is arranged along screw radial direction.
By adopting technique scheme, by being provided with pad in the joint of screw head and screw rod, make screw convenient when in use, eliminate when generally using, the step of assembling screw and pad, decrease screw when dismantling simultaneously, the situation that pad drops, convenient and practical, simultaneously, pad is had a certain degree to outer ring setting by inner ring, make screw when tightening, first contacted to fastener surface by pad outer ring, because pad is provided with several angle, during screw-driving, compression gasket, pad is made to produce elastic potential energy, screw is made to produce a good relaxation effect, the wear phenomenon through producing because of dismounting and installation process between firmware and screw surface can also be avoided simultaneously, the deflection angle of pad is arranged to 3 ° to 5 °, by test, 3 ° of settings to 5 ° of angle of yaw, the best can be all reached by the locking effect of screw when tightening with relaxation effect, pad arranges build joint, and arrange along screw radial direction, make the angled pad of band when screw-driving, launch by build joint, when screw needs to turn on, there is certain elastic force, make the more convenient use of screw.
The utility model is set to further, and build joint is provided with four roads, and four road build joints are uniformly distributed along on circumferential screw direction on pad.
By adopting technique scheme, pad being offered the four equally distributed build joints in road, passes through build joint, packing ring is divided into four arc-shaped pads, when pad is squeezed, can launches on build joint, pad is extruded and produces certain elastic force, thus there is model pine effect.
The utility model is set to further, and screw rod is also provided with screw thread, pad between screw head and screw thread, pad and screw body one-body molded.
By adopting technique scheme, pad is arranged between screw flight and screw head, can the step of less screw assembled gasket in use, and pad and screw body one-body molded, not only avoid the situation that packing ring is lost when screw does not use, bolt structure intensity can also be strengthened, make the connection of screw more stable.
The utility model is set to further, and pad is annular gasket, and annular gasket internal diameter is identical with screw diameter, and external diameter is greater than screw head diameter.
By adopting technique scheme, ring segment is arranged to by pad, and screwing can be coordinated practical, and pad external diameter is greater than screw head diameter, makes screw when tightening, and action range is larger, strengthens join strength.
The utility model is set to further, and screw rod is arranged to hemispheric rounded tail relative to the other end of screw head.
By adopting technique scheme, the other end of relative for screw rod screw head is arranged to rounded tail, when by screw-driving, rounded tail can aim at tapped hole fast, facilitate operative, simultaneously the setting of rounded tail, when for aiming at tapped hole, cut can not be produced, convenient and practical and beautiful shape to fastener surface.
The utility model is set to further, and the other end of the relative screw head of screw rod is arranged to cone structure.
By adopting technique scheme, cone structure can make screw more easily aim at tapped hole, in the process of tightening, more convenient to operate, when threaded-hole-block, can be the foreign matter in tapped hole be selected into tapped hole inside along the screw head of taper, simultaneously at some special occasions, can also be fixed as nail to fastening piece.
Compared with prior art, the utility model has the advantage of: by pad and screw one-body molded, decrease the step of screw assembled gasket in use, convenient, practical, packing ring is set to the angle of 3 ° to 5 ° simultaneously, and screw can be made when tightening to have good relaxation effect, is convenient to dismounting.
