Description
Technical field
The present invention relates to a kind of fastening piece, relate in particular to a kind of anti-loosing and anti-assembling nut.
Background technique
The anti-assembling nut of prior art is that axial symmetry is made two by dark gradually shallow arc groove on the wall of internal thread, the axial length of groove is the pitch of 2.5-4.5, and in groove steel pin of each security protection or steel ball, and then with the fixing relative position of steel pin or steel ball of core plug and end face back-up ring.The anti-theft nut of this class has three deficiencys: the one, and open arc groove on the wall of internal thread, the destruction of double thread is bigger, is unsuitable for being used for fastening; The 2nd, only stop that by steel pin or steel ball nut rotates, can not be locking; The 3rd, this class nut usually needs the bolt with lengthening when the steel part screw pair connects, be equipped with packing ring again, tightening nut, anti-assembling nut, binding nut, complex structure, assemble loaded down with trivial details, the increase user cost.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of anti-loosing and anti-assembling nut is provided, only form, have fastening, locking, anti-unloading functions by nut body, overcoat, packing ring, simple in structure, practical.
For achieving the above object, the present invention adopts following technological scheme: a kind of anti-loosing and anti-assembling nut, comprise nut body, overcoat, nut body is provided with the internal thread of perforation, nut body upper end external diameter is provided with shoulder, the shoulder external diameter is greater than the internal diameter of overcoat, nut body and overcoat cooperation place are provided with the ratchet mechanism that constitutes one way engagement, and ratchet mechanism is made of one or more ratchet on the external diameter that is arranged on nut body and the one or more ratchet that is arranged on the internal diameter of overcoat.
The present invention further is set to be provided with grooving on the nut body vertically, and the axial height of grooving is less than the thickness of nut body.
The lower end external diameter that the present invention further is set to nut body is provided with outer cone, is provided with packing ring in the nut body lower end, and the packing ring center portion forms female cone, and outer cone and female cone constitute the tapering secure fit.
The present invention is by the improvement to anti-loosing and anti-assembling nut, between nut body and overcoat, ratchet mechanism is set, screw terminal at the nut body outer wall is provided with grooving vertically, and outer cone is set in the nut body lower end surface, and packing ring is set in the nut body lower end, offer female cone in the packing ring center portion, rely on the one hand on the nut body grooving and in, the cooperation of outer cone makes nut body make radial contraction when assembling, the matching gap of elimination and rod member clamps rod member, reaches locking, fastening purpose, utilize ratchet mechanism to realize single load bearing on the other hand, when the reverse rotation overcoat, be enclosed within on the nut outward and skid, prevent that overcoat from separating with nut body, reach anti-purpose of unloading, the present invention has fastening, locking, anti-unloading functions, simple in structure, practical.

Embodiment
As shown in the figure, specific embodiments of the invention are a kind of anti-loosing and anti-assembling nuts, comprise nut body 1, overcoat 2, nut body 1 is provided with the internal thread of perforation, nut body 1 upper end external diameter is provided with shoulder 11, shoulder 11 external diameters are greater than the internal diameter of overcoat 2, nut body 1 and overcoat 2 cooperation places are provided with the ratchet mechanism that constitutes one way engagement, ratchet mechanism is made of two ratchets on the external diameter that is arranged on nut body 1 12 and two ratchets 21 being arranged on the internal diameter of overcoat 2, screw terminal at nut body 1 outer wall is provided with grooving 13 vertically, the axial height of grooving 13 is less than the height of nut body 1, be that grooving 13 does not switch at the end at axial direction, the lower end external diameter of nut body 1 is provided with outer cone 14, be provided with packing ring 3 in nut body 1 lower end, packing ring 3 center portions form female cone 31, and outer cone 14 and female cone 32 constitute the tapering secure fit.
The quantity that is arranged on the ratchet 12 on the external diameter of nut body 1 and is arranged on the ratchet 21 on the internal diameter of overcoat 2 can be one or more, and is corresponding just passable as long as both ratchets are provided with quantity.Grooving 13 on the nut body 1 can be for a plurality of, as long as can reach the effect of radial contraction.
Of the present invention fastening, following two aspects of locking effect performance, the ratchet mechanism that between nut body 1 and overcoat 2, is provided with, effect is to drive nut by external force to rotate synchronously, in during counter-rotating, outer ratchet is thrown off, and the effect of the inside and outside circular cone secure fit between grooving 13 on the nut body 1 and nut body 1 and the packing ring 3 is to have pasted and also produce radial contraction power when continuing axial displacement takes place when connecting object screwing process middle washer 3 bottom surfaces when nut body 1, make nut body 1 make radial contraction to the center of circle gradually, eliminate the matching gap of screw pair, and clamp the outside thread rod member.
It is of the present invention that anti-what unload that principle leans on is the single load bearing principle of ratchet mechanism, when wanting reverse back-out, the stress surface of inside and outside ratchet is then thrown off, nut body 1 is existing to axially fasten pretightening force and clamping force radially, can force the distortion of overcoat 2 thin-walleds like this, ratchet 12 on the nut body 1 is distortion simultaneously also, and overcoat 2 is skidded on nut body 1, thereby plays the anti-purpose of unloading.
In sum, that the present invention has is fastening, locking, anti-unloading functions, and simple in structure, practical.
Shoulder 21 joints with nut body 1 on the overcoat 2 in another embodiment of the present invention are provided with interior round platform shoulder 22, shoulder 11 Spielpassung of interior round platform shoulder 22 and nut body 1, round platform shoulder 23 in the lower end surface of overcoat 2 is provided with, interior round platform shoulder 23 and packing ring 3 Spielpassung, the upper-end surface of the upper-end surface of overcoat 2 and nut body 1 maintains an equal level, make anti-loosing and anti-assembling nut outward appearance better appearance by such setting, more meet the standard of fastening piece.
