Between female thread, the threaded fastener of axial gap and radial clearance takes on this important task.
Summary of the invention
Present disclosure is to provide the stop nut of a kind of novelty, particularly can eliminate radial clearance between thread simultaneously
And axial gap, wedging type anti-loosening locking is on bolt thread, and the nut making to fasten the most in advance on this bolt the present invention will not pine
The effect of dynamic also energy retaining.
Elastic cone wedging type stop nut of the present invention is the high nut by band inner circle taper hole and band outer cone boss
Thin nut combine, female cone nut is to process one section of inner circle taper hole, outer cone at the right-hand member of standard hex high nut
Nut is to process one section of outer cone boss at the left end of standard hex thin nut, and its tapering size of both tapered segments is relative
Should, it is open-minded that the conical boss of hexagon thin nut left end and right-hand member are respectively provided with at least two one end in the axial direction, and the other end is not opened
Logical blind slot, the blind slot that left and right is outputed all is uniformly distributed in the plane on the basis of each end face, and two ends, left and right are divided along axis
The blind slot interlaced arrangement of cloth.The aperture of standard hex high nut right-hand member inner circle taper hole small end should be less than standard hex thin nut left end
The diameter at outer cone boss small end circular cone position, and more than the size in the big footpath of female thread.Standard hex high nut right-hand member female cone
Hole and the tapering of standard hex thin nut left end conical boss require corresponding, and its cone angle is greater than 3 °, its objective is for
Prevent from producing self-locking and exiting difficulty during dismounting.In addition its width of blind slot that on standard hex thin nut, two ends are uniform is at least
More than 1mm, and up/down perforation, its objective is to prevent elastic cone wedging type stop nut of the present invention groove width when application
When being retracted to extreme position, still embrace incessantly bolt thread and do not reach the effect of Anti-loosen stop.
Thick hexagonnut in use, is first screwed into and need to fasten by elastic cone wedging type stop nut of the present invention
On bolt, but band in one end of inner circle taper hole towards outer end, after being screwed up with a wrench, then the thin nut by band conical boss
Conical boss one end is made to be introduced on bolt, until its projection section outer cone boss contacts, now with high nut inner circle taper hole
Two nuts thick, thin are connected, owing at first having eliminated its thread and bolt when being screwed into high nut with usual manner
The axial gap of thread, after the thin nut that is screwed into when continuing to turn with spanner again, blind slot uniform on the conical boss of its left end
To tighten up under the effect of tapering, then the female thread thread of thin nut conical section will be held tightly on the thread of bolt, eliminates
Radial clearance therebetween.The hexagonal position of thin nut right-hand member is twisted the tightest by spanner, then it eliminates the effect of radial clearance more
Good, now the thickness of the present invention, thin two nuts have been connected under the effect of cone, and each take elimination axial gap and
The effect of radial clearance, serves the effect reliably preventing the present invention from getting loose.Owing to cone is the stereogenic of plane voussoir,
Open-blind groove uses the mode of radial contraction to reach the purpose of locking thereon.Therefore the present invention is called that elastic cone wedging type is locking
Nut.When dismantling elastic cone wedging type stop nut of the present invention, it is right that available conventional direction spanner is first inserted in thin nut
End outer-hexagonal position, the tapered segment the most firmly turning then thin nut left end is separated from the conical bore of high nut right-hand member,
Blind slot thereon is gradually flicked reinstatement, until thin nut is removed under elastic effect.The most again with spanner with often
The method of rule reversely pulls down the high nut being tightened.
