This anti-loosening, antirust bolt utilizes friction wire circlip 4 as engagement indirectly, and utilizes the feature of spring and tribology principle to design.The bolt of, rustless property anti-loosening as having is when it has anti-loosening, rustless property when needing fastening interior threaded part to be used.It is by anti-loosening, antirust bolt body 1, and cone body rod 2 is alleviated in locking, card end jacking block 3, and friction wire circlip 4, built-in anti-loosening brute spring 5, friction jacking block 6, built-in cone jacking block 7 is formed.Anti-loosening, the outer screw thread of antirust bolt body 1 is local or all meshing friction wire circlip 4 by friction wire circlip mounting groove 16, friction steel wire card end 9,10 and card end jacking block 3 be positioned at card and hold jacking block hole 11, in 12, card end jacking block arc contact surface 17 contacts with cone arc contact surface 15, card end jacking block end face 18 respectively with friction steel wire card end 9,10 contact, friction jacking block 6 is positioned at friction jacking block hole 21, friction jacking block arc contact surface 19 contacts with cone arc contact surface 15, friction jacking block end face 20 contacts with friction wire circlip 4, locking is alleviated cone bottom surface of contact 14 and is contacted with built-in cone jacking block surface of contact 22, and built-in cone jacking block bottom 23 contacts with built-in anti-loosening brute spring 5.
Described anti-loosening, antirust working bolt principle is: before this bolt is screwed into the fastening interior threaded part of need, with screw-driver locked with bolts being alleviated end 13 earlier screws in, making locking alleviate cone body rod 2 moves down, make with cone arc contact surface 15 contacted card end jacking block arc contact surfaces 17 and friction jacking block arc contact surface 19 and disengage therebetween, card end jacking block 3 and friction jacking block 6 inwardly shrink under the effect of friction wire circlip 4, because the inherent characteristic of spring friction wire circlip 4 restores to the original state, and binds round on anti-loosening, antirust bolt body 1.Then anti-loosening, antirust bolt body 1 is screwed into when needing fastening interior threaded part extremely tight, re-uses screw-driver locked with bolts alleviation end 13 is screwed out to dominant bit.Owing to rise on the cone position of locking alleviation cone body rod 2, cone arc surface of contact 15 closely contacts with friction jacking block arc contact surface 19 with card end jacking block arc contact surface 17, to block end jacking block 3 outwards extrudes with friction jacking block 6, the also outside expansion of being located at simultaneously in the friction wire circlip mounting groove 16 of friction wire circlip 4 closely contacts with interior threaded part tooth root flank of tooth portion, and produce the radial elastic distortion, between tooth root, flank of tooth portion and friction wire circlip 4 surface of contact, produce huge pressure.This moment is when high vibration or when turning anti-loosening, antirust spiral shell main body 1, because of having produced huge pressure between anti-loosening, antirust bolt and the interior threaded part, make friction wire circlip 4 produce more preceding bigger radial elastic distortion and longitudinal elasticity distortion, huge the increasing of footprint pressure between interior threaded part and the friction wire circlip 4, so between its surface of contact, produce huge frictional force, thereby have anti-loosing effect.The effect that built-in cone jacking block 7 and built-in anti-loosening brute spring 5 are set is for overcoming under the high vibration condition, prevents that locking from alleviating cone body rod 2 and moving down naturally owing to high vibration and cause lockout failure setting.Because the top of built-in anti-loosening brute spring 5 is pressing closer built-in cone jacking block bottom 23, built-in cone jacking block surface of contact 22 is alleviated cone bottom surface of contact 14 closely contact mutually with locking, and the working state of built-in anti-loosening brute spring 5 is in squeezed state all the time, and its enormous function power is made progress all the time.Even so just guarantee under the high vibration condition, locking is alleviated cone body rod 2 and not only can not moved down, and can only be by moving on the counter clockwise direction, thereby more make the footprint pressure between cone arc contact surface 15 and card end jacking block arc contact surface 17 and the friction jacking block arc contact surface 19 further increase, card end jacking block 3 and friction jacking block 6 force friction wire circlip 4 outside expansions and produce bigger radial elastic distortion and longitudinal elasticity distortion, friction wire circlip 4 and the area of contact and the contact pressure that need fastening interior threaded part have been increased, making that frictional force is huge increases, and produces to shake tighter and tighter to reach better locking effect.Antirust work is after anti-loosening, antirust bolt body 1 being screwed into the fastening interior threaded part of need and before the non-locking, grease nipple is screwed in locked with bolts to be alleviated in the butter filler hole 8, the butter of annotating then, after treating to be full of butter in anti-loosening, the antirust bolt body 1, grease nipple is screwed out, thereby reach rust-proof effect.When anti-loosening, antirust bolt is in the lock state, and when needing dismounting, with screw-driver locked with bolts alleviation end 13 being screwed in feasible locking alleviation cone body rod 2 moves down, this moment, card held the footprint pressure between jacking block arc contact surface 17 and friction jacking block arc contact surface 19 and the cone arc contact surface 15 to reduce, until disengaging.And the wire circlip 4 that rubs this moment also disengages with the fastening interior threaded part of need under the situation of external force losing, because the characteristic of spring, friction wire circlip 4 restores to the original state, driving card end jacking block 3 and friction jacking block 6 simultaneously inwardly shrinks, bind round on anti-loosening, antirust bolt body 1, thereby finish released state.Specifically consult each schematic representation.
