The described tapered collar outer side surface of described elastic ring is made smooth surface, or the described tapered collar outer side surface of described elastic ring is made the shape of threads surface; The outer side surface of described annulus is a smooth surface; The inner side surface of described composition ring is a smooth surface.When described tapered collar outer side surface was shape of threads, the internal surface of the described taper mouth of described awl mouth nut also should be made the flank of thread that the screw thread with described tapered collar outer side surface matches.
Described elastic ring adopts the rubber-like material to make, this material can make described elastic ring can not rupture when reaching tightening state on the bolt being squeezed in by a described awl mouthful nut, and still recovery or almost recover original shape after a described awl mouth nut unloads from the tightening state pine.Above-mentioned elastic material comprises metal, nonmetal, organic and inorganic macromolecule material, and their composite material.
The working principle of a kind of antivibration lock nut of the utility model is: before described awl mouthful nut screwing clamping, described elastic ring has at least a part to be placed on the outside of described awl mouthful nut, and has a part of space at least in the described taper mouth of described awl mouthful nut.When bolt that a described awl mouthful nut is screwed on, but before not tightening as yet, the described elastic ring of described more precisely awl mouthful nut closely contacts before the fastener, and described elastic ring does not contact with bolt or slight contact only arranged; And when described awl mouthful nut screwing clamping when described elastic ring closely touches fastener, described elastic ring will the be squeezed effect of power and compression in the described awl mouthful nut, tightly more stubborn, the extruding force that described elastic ring is subjected to is just big more.In tight condition, described elastic ring can impose on extruding force described awl mouthful nuts and bolt simultaneously, thereby has strengthened the self-locking strength of nut and bolt.Because the elasticity of described elastic ring self structure and the elasticity of described elastic ring bulk material or described elastic ring surfacing can produce the effect that absorbs or weaken to the ripple that shakes, and make a described awl mouthful nut have the antivibration locking functions.When a described awl mouthful nut was unscrewed, the extruding force suffered along with described elastic ring reduced, and described elastic ring can be gradually expose from the described taper mouth of described awl mouthful nut, and unclamped bolt gradually and return to original relaxed state.
If desired a described awl mouthful nut is positioned at the somewhere, only needs with something described elastic ring is withstood, treat again something to be taken away behind the described awl mouth nut screwing clamping and get final product at this place.
From the above, a kind of antivibration lock nut of the present utility model compared with prior art has when tightening energy automatically enhancing self-locking strength function, and the better characteristics of antivibration anti-loosening property also are simple in structure and convenient in use simultaneously.
