Embodiment
As shown in Fig. 1-Fig. 4, the utility model discloses a kind of dual anti-loosing nut external member, comprise nut 1 and packing ring 2, a packing ring 2 axially end face is the counterface 21 with nut screw connection, the axial other end of packing ring is tight locking face 22, the face that nut coordinates with packing ring is bearing surface 11, on the counterface 21 of packing ring and nut, bearing surface 11 is corrugated surface, corrugated surface is its protruding and evenly spaced annular spread of groove, there is between the counterface 21 of packing ring and the bearing surface 11 of nut the operable state that can coordinate along the sense of rotation changing of the relative positions, and the lockup state of occlusion locking mutually.By above-described embodiment, after nuts and washers is tightened, the ripple projection on nut corrugated surface embeds the corrugation grooves on packing ring corrugated surface, and two ripples extrude mutually, thus serve the effect of locking, because nut and packing ring fitting surface to relatively rotate, when the corrugated surface projection 24 of nut skids off corrugated surface groove 14 on packing ring, namely when projection is to projection, corrugated surface produces lifting tension force, improve the coupling mechanism force of faced by washer locking fastened, effectively play locking effect, during dismounting, when the tight lock power of packing ring and fastened is greater than the snap-in force of packing ring and nut, turn on nut, resiliently deformable is produced between nuts and washers, the projection 24 between corrugated surface is forced to skid off groove 14 to projection to projection, groove 14 part is slipped into again by protruding 24, thus realize performance and the structure that dismounting does not destroy nuts and washers, indirectly realize reusing.
Nut 1 is flange surface nut 1, nut flange face is extended the round platform 12 with through hole, and the axis that round platform 12 end face extends band through hole stretches out body 13, and packing ring 2 is set in and axially stretches out on body 13.By above-described embodiment, the flanged surface on flange surface nut serves the effect of protection nut resistance surface, and round platform can coincide and packing ring; make structure compacter; the packing ring that is arranged so that axially stretching out body can position rotating, conveniently installs, and nut coordinates more reliable and stable with packing ring.
Round platform end face is the bearing surface 11 of nut, and bearing surface is convex cone face, and ripple is located on this conical surface, and the counterface 21 of packing ring is provided with the corresponding concave cone face of the conical surface therewith.By above-described embodiment, nut is connected with the pad conical surface, increases surface of contact, thus improve frictional force, add the anti-loosing effect of packing ring and nut screw connection, ripple concave cone face and ripple convex cone mask have mutual interlocking in addition, make packing ring and nut screw connection more reliable and stable.
Axially stretch out the through hole length that body 13 length is less than packing ring 21.By above-described embodiment, the tight locking face on packing ring can be made to contact completely and fastened, thus improve the tight lock power of tight locking face and fastened.
Tight locking face 22 is provided with the radial protrusion bar 23 placed, and protrude bar 23 annular distribution on tight locking face 22, the cross section protruding bar 23 is square, and the longitudinal section of protruding bar 23 is square.By above-described embodiment, under pulled condition, relatively soft fastening surface can be formed and squarely form mirror image square structure with packing ring, makes packing ring achieve self-locking friction locking, during dismounting, forces and unclamp from nuts and washers cooperation place.
Nut 1 and packing ring 2 are cold-heading part.By above-described embodiment, the structure of packing ring and nut is conducive to one-body molded, uses cold header to produce and effectively can improve manufacturing efficiency.
Dual anti-loosing nut external member provided by the utility model realizes locking working principle and is: when connected piece is relatively hard material, the protrusion bar structure adopted bottom packing ring is multiple spot or linear contact lay with being connected face, can realize increasing friction factor, play the effect that friction is locking, when needing to take off, only need overcome friction just can unclamp, when connected piece is relatively soft material, protrude bar loose structure and connected piece surface can be squeezed out relative protrusion bar texture grooves, two surface of contact become the tight lock status of occlusion, packing ring is made to realize self-locking friction locking, now the tight lock power of packing ring and fastened is greater than the snap-in force of packing ring and nut, when producing vibrations or other modes destroy, because nut and packing ring fitting surface to relatively rotate, when the corrugated surface projection of nut skids off corrugated surface groove on packing ring, namely when projection is to projection, corrugated surface produces lifting tension force, improve the coupling mechanism force of packing ring, effectively play locking effect, during dismounting, when tight lock frictional force due to packing ring and fastening surface is greater than the snap-in force of packing ring and nut, turn on nut, make to produce resiliently deformable between nuts and washers, the projection between corrugated surface is forced to skid off groove to protruding to projection, groove part is slipped into again by projection, continue to turn on nut, corrugated surface slips into groove part by projection again, now the gap of nuts and washers can increase, when continuing to turn on nut, torsion can be more and more less, thus realize performance and structure that dismounting does not destroy nuts and washers, indirectly realizes reusing.
