Specific implementation mode
It elaborates to the specific implementation mode of the present invention below in conjunction with concrete condition and embodiment.
Shown in Fig. 1,2, present invention one kind not Unscrewed screw nut, including nut body, there are screw hole 2, spiral shell in 1 center of nut body
There is screw thread on the peripheral wall of hole, the stress surface of nut body bottom surface is inclined-plane 3, the A points on nut body one side and the B points of corresponding another side（B
Point is virtual point, is common nut stress bottom surface）Between line 4 it is parallel with plane on nut body, the C points and A of B points lower part
The central axis of line and screw hole between point is oblique, i.e., screw hole 2 is not vertical with the inclined-plane 3 of nut body bottom surface stress
's.
In order to ensure using effect and a kind of not Unscrewed screw nut, including nut body easy to use, described, nut body
For plane perpendicular in there is screw thread on screw hole 2, screw hole peripheral wall, nut body bottom surface is parallel with upper plane, and nut body bottom surface is placed in lower part pad
In the plane groove 6 at 5 center of piece, the line 4 between the A points on gasket one side and the B points of corresponding another side is put down on nut body
Face is parallel, and the central axis of line and screw hole between the C points and A points of B points lower part is oblique, i.e. screw hole 2 and gasket bottom surface
The inclined-plane 3 of stress is not vertical, constitute gasket be on one side it is thick, while the inclined-plane of bottom stress that approaches；
The gasket is the thin slice of not uniform thickness；The nut body periphery is polygon, generally regular hexagon；The pad
The groove at piece center is in the identical regular hexagon of size corresponding with nut outer periphery regular hexagon；
The inclined-plane 3 of the stress is the line of the highest point and the lowest point of stress surface, is non-smooth plane；
The slope level inclination angle of the stress is best according to the screw thread inclination of screw specification.
The present invention is in use, as shown in Figure 5,6, the first clamped workpiece 7, the second clamped workpiece 8 are installed through bolt 9
Together, by screw, nut spinning on bolt, bolt is fixed firmly by spanner tightening nut body 1, keeps stress inclined-plane 3 tight
It is tightly closely joined together, two clamped workpiece can be securely joined together with clamped workpiece surface, and due to
Stress surface is inclined-plane, constitutes the inclination stress shape of screw and nut, that is to say, that the bottom surface of screw and nut be both a stress surface again
It is a vibrations rubbing surface, while is also the rotational trajectory face of a nut, the loosening of screw is shaken by the friction of nut bottom
Caused by dynamic gradually sliding, and find that the stress surface of nut is relatively vertical, the screw thread of screw rod and nut with screw hole
Between have certain gap, so on top nut the characteristics of, can pass through and change hanging down between nut stress surface and screw hole
Squareness, as shown in Figure 1（It can be seen that the stress surface of nut is that some are inclined, it is according between screw rod and nut screw thread
Gap size, to adjust stress plane inclination）Although having done a slight improvement, i.e. spiral shell in the structure of plain nut
The part of female inclined bottom surface, that is, one gradually change when clamping workpiece nut rotational trajectory and shake frictional direction
Component proves that the workpiece of this nut fastening of shock detection, nut will not all be loosened anyway by testing（Unless nut
Body is destroyed）, and be just not easy with after this nut clip clamping of workpieces, rethinking to unclamp, if not fastening screw rod only with one
A spanner pine nut is Song Bukai, and nut can be followed by screw rod and rotate together, and is exactly that nut stress surface rubs with workpiece stress surface
Some thin iron pins are wiped, nut will not be separated with screw rod, and only fastening screw is motionless with strength to unclamp nut, so this
The nut of out of plumb can achieve the effect that never becoming loose in use between kind nut stress surface and screw hole, it is clamping workpiece
Operating track and the vibrations frictional direction for having gradually changed nut afterwards, intuitively see tilt nut and screw rod, nut stress surface is but
Perpendicular to screw rod.
Think equally to achieve the effect that not allow loosened screw, a bit inclined mode of this stress surface for seeming nut is transferred to
On the workpiece or gasket to be clamped,（This section is crossed out, because what it lifted be counter-example is not Fig. 3 Fig. 4）Allow workpiece or gasket by
Some gradients of power face so that clamp workpiece back nut tilt and screw rod, as long as but this method by practice test gasket not
With nut teeth integrator, the tight effect of screw is all not achieved in they, because of the least bit of difference, a thousand li of mistake, although
Tilted and screw rod clamping workpiece back nut, but nut stress surface also tilts therewith, i.e., nut stress surface with nut thread still
It is consistent, so but can not change operating track and the vibrations frictional direction of nut after clamping workpiece.
Unscrewed screw is not to change the inclination of nut stress surface using plain nut and screw flight gap to the present invention
Degree so that the operating track of nut is changed after clamping workpiece and shakes the direction realization of frictional force, according to this feature,
This tight nut can be allowed to resolve into a plain nut and a tight gasket, i.e., there is ditch at center above gasket
Slot can allow motionless in nut inserted shim, and gasket and nut is enable when tightening nut to rotate together such as the same entirety, gasket
It is not vertical, such gasket and for example same entirety of nut between lower end stress surface and nut bore after combining, gasket
Stress surface changes the rotational trajectory and vibrations frictional direction of nut shim entirety such as the stress surface of nut after clamping workpiece, this
One tight gasket of sample and a plain nut just constitute the nut of a never becoming loose, can seem in commercial Application
It is more more flexible.
It can also be used in spiral shell also according to this change nut operating track and the principle for changing vibrations direction
On bar, but screw rod requirement cannot be long, and otherwise the gap between screw thread does not ensure the required inclination of long screw rod
Degree.
The stress surface of the present invention not loose nut have to be not necessarily smooth plane, as long as stress peak and stress
Face where the line of minimum point can make whole nut stress surface have certain inclination, play after clamping workpiece gradually
Change the operating track of nut and shakes the effect of frictional direction.
The present invention is through site test and application, once two clamped workpiece are reinforced through bolt with screw and nut of the present invention
Afterwards, under the action of a variety of different vibration forces, by the experiment of 72h, all without finding loose phenomenon, and by 30 examinations
It tests, all obtains same technique effect, at the same time, make same experiment, nut loosening with using normal screws nut
Rate is up to 100%, that is to say, that all there is loose phenomenon, and the present invention is all without loose phenomenon, is that the prior art can not
It compares, due to that will not be loosened using process, be otherwise known as never becoming loose screw, ensures the service life of equipment
And production efficiency, but also maintenance cost and cost are substantial saved, and waste product pollution on the environment is also reduced, it is energy saving
Environmental protection, is the big innovation on screw and nut, and economic and social benefit is huge.
