Description
Technical field：
The present invention relates to the surface nut in fastener areas, especially a kind of inclined-plane self-locking nut.
Background technology：
Stop nut is the securing member used cooperatively with internal thread and with bolt, with internal thread and with spiral shell use cooperatively to
Transmission motion or the machine components of power.Nut is used with bolt, screw fit, plays connection fastening mechanism effect.Stop nut
Typically it is attached on screw thread so that special engineering plastics are permanent, makes internal and external threads in the process that tightens, engineering plastics is extruded
And powerful reaction force is produced, substantially increase the frictional force between internal and external threads, there is provided to the absolute resistance for vibrating.
At present existing stop nut structure design is all complex, and its production cost is higher.Structure is relatively simple, with low cost
Stop nut it is less, actual industrial production and the needs for using can not be met.
The content of the invention：
It is oblique that the technical problem to be solved in the present invention is to provide a kind of modified for effectively preventing nut in fastening structure from occurring to loosen
Face self-locking nut.
To solve the above problems, the present invention is achieved by the following technical solutions：
A kind of inclined-plane self-locking nut, including surface nut body and beveled washer；Have and surface nut on the beveled washer
Body with angle inclined-plane, bevel angle be 5-70 °；The surface nut body passes through oblique after fitting with the inclined-plane of beveled washer
Face nut body internal thread is arranged on matched bolt；The beveled washer center is provided with to be easy to be enclosed within bolt simultaneously
The through hole for making beveled washer be occurred tiltedly to move by surface nut body torsion, the through hole is additionally provided with beveled washer intersection to be made tiltedly
Face packing ring can be engaged on bolt the deep-slotted chip breaker for carrying out self-locking after tiltedly moving.When surface nut body is fitted installation with beveled washer
After on the bolt, surface nut body is tightened, beveled washer is subject to after torsion to be occurred tiltedly to move in through hole, while deep-slotted chip breaker occlusion
So as to reaching the effect of self-locking on the screw thread of bolt.
Preferably, the surface nut body is the knot of the hex nut by part thereon and the inclined-plane annulus of lower part
It is combined into, the inclined-plane of inclined-plane annulus is corresponding with the inclined-plane on beveled washer.
Preferably, the through hole is eccentric orfice so that beveled washer is more beautiful with the use of rear entirety with surface nut
See, the eccentric throw in the hole can be determined according to the size of beveled washer, the stress size of surface nut body.
Preferably, to the inclined plane of edge tilt centered on the lower surface of the beveled washer, angle of inclination is 1-10 °
Can prevent from the lower surface of beveled washer from contacting with bolt end long-time to wear and tear.
Preferably, the angle of inclination of the lower surface is 2-8 °.
Preferably, the angle on the inclined-plane is 10-60 °.
Preferably, the angle on the inclined-plane is 20-50 °.
Preferably, the surface nut body and beveled washer need synchronous axial system during locking, by two tiltedly
The interaction in face, can prevent surface nut body from occurring to turn in the case of surface nut body and beveled washer are nonsynchronous
It is dynamic, play a part of self-locking.
The material hardness that above-mentioned beveled washer is adopted prevents the arc on beveled washer less than the material hardness that bolt is adopted
Shape groove is engaged in damaged screw after the screw thread of bolt.
Compared with prior art, the invention has benefit that：Apparatus of the present invention simple structure, convenient use can be entered
Row batch production；Being engaged on the screw thread of bolt by the deep-slotted chip breaker on beveled washer can effectively prevent nut from being affected by external force
Loosen, in can be widely used in the structure that nut imitates pine.

Specific embodiment：
Below in conjunction with the accompanying drawings and specific embodiment describes the present invention：
A kind of inclined-plane self-locking nut as shown in Figure 1, Figure 2 and Figure 3, including surface nut body 1 and beveled washer 2；It is described oblique
Face nut body 1 is made up of the combination of the inclined-plane annulus 12 of the hex nut 11 and lower part of part thereon, the inclined-plane pad
There is the inclined-plane with surface nut body 1 with angle, inclined-plane annulus 12 is all located at 5- with the bevel angle on beveled washer on circle 2
Between 70 °；The surface nut body 1 is arranged on after fitting with the inclined-plane of beveled washer 1 by the internal thread of surface nut body 1
On matched bolt 3；The center of beveled washer 2 as shown in Figure 4 is provided with to be easy to be enclosed within bolt 3 and make beveled washer 2
By the through hole 21 that the torsion of surface nut body 1 occurs tiltedly to move, the through hole 21 is additionally provided with the intersection of beveled washer 2 and makes inclined-plane pad
Circle 2 can be engaged on bolt 3 deep-slotted chip breaker 22 for carrying out self-locking after tiltedly moving.Through hole 21 as shown in Figure 5 is eccentric orfice, it is ensured that tiltedly
Face packing ring 2 is more attractive in appearance with the use of rear entirety with surface nut 1, to edge centered on the lower surface 23 of the beveled washer 2
Inclined inclined plane, angle of inclination is 1-10 °, preferred scope 2-8 °.

Line is tightened on bolt 3, continues to screw surface nut body 1, and the beveled washer 2 of the lower section of surface nut body 1 is made by torsion
There is tiltedly shifting in through hole 21 along inclined-plane with after, the deep-slotted chip breaker 22 on beveled washer 2 is engaged on the screw thread of bolt 3, due to two
The interaction on individual inclined-plane, in the case of surface nut body 1 and beveled washer 2 are nonsynchronous surface nut body can be prevented
1 rotates, while the through hole 21 of beveled washer 2 makes deep-slotted chip breaker 22 be engaged on screw thread in the case where torsion is effect, it is ensured that inclined-plane
Packing ring 2 does not produce rotation, so as to play a part of self-locking.First surface nut body 1 glued with packing ring 2 by glue when in use
It is combined, is easy to be screwed on matched bolt 3, continues to tighten surface nut body 1, the inclined-plane spiral shell in the presence of external force
There is dislocation skew in maternal body 1, glue comes off, while the deep-slotted chip breaker 23 on beveled washer 2 is engaged with beveled washer 2 along inclined-plane
On the screw thread of bolt 3.
In order to further appreciate that the shockproof effect of the present invention, the present invention is detected by oscillation crosswise test.
It is as shown in Table 1 and Table 2 the test result that oscillation crosswise test is carried out to the present invention, amplitude is worked as can be known from Table 1
For ± 1.2mm, 5.0 ± 0.5KN of vibration force, frequency is 12.5Hz, and vibration number is 3000 times, and initial axle power is entered for 36.68KN
During row test, remaining axle power is 75.68% with initial axle power ratio；
In another embodiment, when amplitude is 1.6mm, 7.8 ± 0.5KN of vibration force, frequency is 12.5Hz, and vibration number is 3000 times
When being tested, initial axle power is 71.60KN, and remaining axle power is 68.40KN, and remaining axle power is with initial axle power ratio
95.53%, still there is larger axle power through repeatedly vibration apparatus of the present invention；
The center line I of table 2 for the present invention characteristic curve, line II is the shockproof screw nut characteristic curve that is applied on railroad track, line III
For the characteristic curve of common antidetonation nut, it is possible thereby to find that apparatus of the present invention compare other shockproof screw nuts, the shockproof time is long,
Shockproof effect is good, stable performance.
