Abstract
The utility model discloses a triangle ball anti-theft nut used for fastening threaded connection components. The triangle ball anti-theft nut comprises a nut body, straight grooves which change from shallow to deep in the thread direction are formed in the inner wall of a screw hole of the nut body in the longitudinal direction, the two longitudinal ends of each straight groove are not communicated, balls are arranged inside the straight grooves, the cross section of each straight groove is triangular, and the balls are in clamping and rolling fit with the tops of the straight grooves respectively. The triangle ball anti-theft nut has the advantages that on one hand, the cross section of the straight grooves is triangular and can effectively clamp the balls and prevent the balls from withdrawing or falling off in the use process, and the anti-detachment effect of the nut is improved; on the other hand, machining and manufacturing are easy and convenient, cost is lowered, and market competitiveness is improved.
Description
Technical field
The utility model relates to a kind of for the fastening nut of scyewed joint member, particularly a kind of triangle ball anti-theft nut.
Background technique
The patent No.: 200720039981.6, patent name: a kind of anti-assembling nut, comprise nut, on the inwall of nut screw, longitudinally offer along the hand of spiral straight trough that from shallow to deep cross section is arc, and longitudinal two ends of straight trough are not for running through, in straight trough, be provided with ball, ball rolls and coordinates with straight trough fornix position, with straight trough tip snap-fit, in nut screw, be provided with a stopper, on the inwall of nut screw, be radially evenly equipped with three straight troughs, on the circumferential outer surface of stopper bottom, be symmetrically arranged with three sheet shape lugs.Its deficiency is: nut profile shape of cross section is dodecagon, can bear to screw strength excessive, in the corner angle distortion that strength can not make nut when excessive that screws of bearing, and the dark cross section straight trough that is arc, easily make ball exit and come off, cause anti-theft nut to lose efficacy.
Model utility content
The problems referred to above that the utility model exists for prior art, provide a kind of for the fastening nut of scyewed joint member, particularly a kind of triangle ball anti-theft nut.
For achieving the above object, the utility model is by the following technical solutions:
A kind of triangle ball anti-theft nut, comprise nut, on the inwall of nut screw, longitudinally offer along hand of spiral straight trough from shallow to deep, and longitudinal two ends of straight trough, not for running through, are provided with ball in straight trough, on the inwall of nut screw, be radially evenly equipped with three straight troughs, in nut screw, be provided with a stopper, on the circumferential outer surface of stopper bottom, be symmetrically arranged with three lugs, straight trough cross section is triangle, and ball rolls and coordinates with straight trough top clamping.
Further, nut profile cross section is positive 20 quadrilaterals.
Further, straight trough cross section is acute triangle.
The beneficial effects of the utility model are: the one, and straight trough cross section is triangle, can effectively block ball, prevent that ball from use exiting and obscission, improve the anti-effect of unloading of nut, the 2nd, nut profile shape of cross section is positive 20 quadrilaterals, what provide screws strength by deficiency so that prevent unloading retaining part distortion or broken, when screw strength while being greater than certain value the corner angle of nut will be out of shape instruments such as causing spanner and skid and cannot dismantle nut, further improved the anti-effect of unloading of nut; The 3rd, processing and fabricating is simple and convenient, reduces cost, has improved the market competitiveness.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Embodiment 1: with reference to accompanying drawing 1-2.A kind of triangle ball anti-theft nut, comprise nut 1, on the inwall of nut 1 screw, longitudinally offer along hand of spiral straight trough 2 from shallow to deep, and longitudinal two ends of straight trough 2 are not for running through, in straight trough 2, be provided with ball 3, on the inwall of nut 1 screw, be radially evenly equipped with three straight troughs 2, in nut 1 screw, be provided with a stopper 4, on the circumferential outer surface of stopper 4 bottoms, be symmetrically arranged with three lugs, straight trough 2 cross sections are triangle, ball 3 rolls and coordinates with straight trough 2 top clampings, straight trough 2 cross sections are triangle, triangle has stability, can roll and coordinate with ball 3 clampings again, prevent that ball from use exiting and obscission, improve the anti-effect of unloading of nut 1.
Embodiment 2: with reference to accompanying drawing 1-2.A kind of triangle ball anti-theft nut, nut 1 profile cross section is positive 20 quadrilaterals, nut 1 profile shape of cross section is positive 20 quadrilaterals, what provide screws strength by deficiency so that prevent unloading retaining part distortion or broken, when screw strength while being greater than certain value the corner angle of nut 1 will be out of shape instruments such as causing spanner and skid and cannot dismantle nut, further improved the anti-effect of unloading of nut 1.
Embodiment 3: with reference to accompanying drawing 1-2.A triangle ball anti-theft nut, straight trough 2 cross sections are acute triangle.
Embodiment 4: with reference to accompanying drawing 1-2., in ball 3 is stuck in triangle straight trough 2, only can there is rotation and roll in a triangle ball anti-theft nut, can not have the rolling of displacement, can effectively avoid ball 3 in use exit and come off.
Embodiment 5: with reference to accompanying drawing 1-2.A kind of triangle ball anti-theft nut, nut 1 profile shape of cross section is positive 20 quadrilaterals, can set more accurately the strength screwing, as long as it is excessive to screw strength, with regard to the corner angle of nut 1, the distortion that will be bound to causes the instruments such as spanner skid and cannot dismantle nut 1.
Although the utility model illustrates and describes by reference to preferred embodiment, but those of ordinary skills should understand, the description of above-described embodiment can be not limited to, in the scope of claims, the various variations in form and details can be done.
