Description
The utility model relates to a kind of fastening piece, particularly a kind of anti-loosening, antirust bolt.
For preventing bolt looseness, ordinary circumstance is at bolt and needs to add spring washer between the secure component, but still can occur loosening phenomenon unavoidably under strong frequent vibration condition.Producing loosening basic reason is between bolt and fastener the back lash to be arranged, and therefore, as watches and reduces this gap and become the key that solves loosening problem.
The purpose of this utility model is to overcome above-mentioned deficiency and provides and have bolt anti-loosening, rustless property, in the hope of solving clamping bolt under the judder condition, the easily loosening problem of bolt.In case after this bolt is screwed into parts and locked, it is loosening bolt body to occur, more can not come off voluntarily, when needs dismantles, can not produce because of the bolt rust and extremely bring the situation of difficult generation to work.
Below in conjunction with accompanying drawing the utility model is made and to further specify.
Fig. 1 is anti-loosening, the antirust bolt complete section of a utility model structure principle chart.
Fig. 2 is anti-loosening, the antirust bolt lateral parts of a utility model sectional view.
Fig. 3 is friction wire circlip figure.
Fig. 4 is the worm's eye view of anti-loosening friction silk piece.
More than label among all figure represent respectively: 1 is anti-loosening, antirust bolt body, 2 are locking alleviation cone screw rod, 3 is anti-loosening friction silk piece, 4 are the friction wire circlip, 5 is built-in anti-loosening brute spring, 6 for locked with bolts is alleviated, the butter filler hole, 7,8 are friction steel wire card end, 9 are locked with bolts alleviation end, 10 are locking alleviation cone screw rod bottom, and 11 is the cone arc contact surface, and 12,13 are friction steel wire card end slot, 14 are friction wire circlip mounting groove, and 15 is anti-loosening friction silk piece arc contact surface.
This anti-loosening, antirust bolt utilizes friction wire circlip 4 as engagement indirectly, and utilizes the feature of spring and frictional force principle design to form.As having anti-loosening, antirust fastening piece, described bolt and the pairing of internal thread fastening piece have anti-loosening, rustless property when using.It is by anti-loosening, antirust bolt body 1, and cone screw rod 2 is alleviated in locking, anti-loosening friction silk piece 3, and friction wire circlip 4, built-in anti-loosening brute spring 5 is formed.The outer screw thread of anti-loosening bolt body 1 is local or all meshing friction wire circlip 4 by friction wire circlip mounting groove 14, two card ends 7,8 of friction wire circlip 4 are positioned at the friction steel wire card end slot 12,13 of anti-loosening, antirust bolt body 1, anti-loosening friction silk piece 3 is in the hole, the left and right sides of anti-loosening, antirust bolt body 1, anti-loosening friction silk piece arc contact surface 15 contacts with cone arc contact surface 11, and locking is alleviated cone screw rod bottom 10 and contacted with built-in anti-loosening brute spring 5.Anti-loosening friction silk piece 3 has identical technical parameter with anti-loosening, antirust bolt body 1.
Described anti-loosening, antirust working bolt principle is: before bolt is screwed into the internal thread fastening piece, to lock alleviation cone screw rod 2 with screw-driver is earlier screwed in by locking alleviation end 9 positive hour hands, making locking alleviate cone screw rod 2 moves down, both disengage this moment and the contacted anti-loosening friction of cone arc contact surface 11 a piece arc contact surface 15, anti-loosening friction silk piece 3 inwardly shrinks under the effect of friction wire circlip 4, and disengages with the internal thread fastening piece.Then anti-loosening, antirust bolt body 1 is screwed onto when tight, re-uses screw-driver and screw out locked with bolts counter clockwise and alleviate end 9 to dominant bit.Owing to rise on the taper position of locking alleviation cone screw rod 2, cone arc contact surface 11 closely contacts with anti-loosening friction silk piece arc contact surface 15, anti-loosening friction silk piece 3 is outwards extruded, the friction wire circlip of being located at simultaneously in the friction wire circlip mounting groove 14 4 also outwards closely contacts with internal thread fastening piece tooth root portion, and the generation resiliently deformable, between tooth root portion and friction wire circlip 4 surface of contact, produce huge pressure.This moment is when high vibration or when turning anti-loosening, antirust bolt body 1, because of having produced huge pressure between them, and full contact between internal thread fastening piece and the friction wire circlip 4, so on its surface of contact, produce huge frictional force, thereby have anti-loosing effect.The effect that built-in anti-loosening brute spring 5 is set is for overcoming under the high vibration condition, prevents that locking from alleviating cone screw rod 2 because high vibration and moving down naturally, causes lockout failure and is provided with.Because pressing closer locking, the top of built-in anti-loosening brute spring 5 alleviates cone screw rod bottom surface 10, its working state is in squeezed state all the time, its enormous function power is made progress all the time, even so just guarantee under the condition of high vibration, locking is alleviated cone screw rod 2 and can not be moved down, and can only be by moving on the counter clockwise direction, thereby the footprint pressure that the arc contact surface 11 of more feasible locking alleviation cone screw rod 2 and anti-loosening friction silk piece arc contact surface are 15 increases, make the 4 outside expansions of friction wire circlip produce bigger resiliently deformable, increased area of contact and the contact pressure of friction wire circlip 4 with the internal thread fastening piece, making that frictional force is huge increases, and produces to shake tighter and tighter to reach better locking effect.Antirust work is that grease nipple is screwed in locked with bolts alleviation, the butter filler hole 6, and the butter of annotating then after treating to be full of butter in anti-loosening, the antirust bolt body 1, screws out grease nipple, thereby reaches antirust effect.When anti-loosening, antirust bolt is in the lock state, and when needing dismounting, hold 9 feasible locking alleviation cone screw rods 2 to move down with screw-driver from locked with bolts alleviation, the 6 interior locked with bolts of the screw-in clockwise alleviations of butter filler hole above the bolt, footprint pressure between anti-loosening friction silk piece arc contact surface 15 and the cone arc contact surface 11 reduces, and breaks away from fully until two surface of contact.And the wire circlip 4 that rubs this moment breaks away from the internal thread fastening piece under the situation of external force losing, because the characteristic of spring, friction wire circlip 4 restores to the original state, driving anti-loosening friction silk piece 3 simultaneously inwardly shrinks, friction wire circlip 4 binds round on anti-loosening, antirust bolt body 1, thereby finishes released state.Specifically consult Fig. 1, Fig. 2.
The cross section of friction wire circlip 4, the geometrical shape size requires to be prismatic, rectangle, ellipse according to purposes and varying strength, and can be waney.
The friction wire circlip 4 of described anti-loosening, antirust bolt can be divided into single or many by the difference requirement of the internal thread fastening piece that matches with it.Shape of its friction wire circlip 4 of difference as required can be semicircle spring, circle spring or around spring.
Described friction steel wire card end 7,8 its means of fixation of difference as required anti-loosening, antirust bolt can be divided into fixed, semi-fixed type.
Described anti-loosening friction silk piece 3 difference as required anti-loosening, antirust bolt can be divided into one or more.
Advantage of the present utility model: novel, anti-loosening, antirust, exempt to use spring washer, installation, convenient disassembly.Not changing original directly use under the fastener constructions situation that needs, can improve service life of equipment and safety reliability, and can realize large-scale standardized production.
