Description
[technical field]
The utility model relates to the technical field of machanical fastener, particularly a kind of technical field of locking nut.
[background technique]
Full-metallic locking nut has three major types, and the first kind is side pressure point full-metallic locking nut, and second largest class is end face pressure point full-metallic locking nut, and the third-largest class is band locking plate full-metallic locking nut.But setter is often difficult to determine that whether nut is fastening and puts in place in actual use, be therefore difficult to guarantee when using for a long time, bolt and nut can not loosen automatically.And in some cases, the loosening of nut, coming off to cause serious accident, causes heavy economic losses.Nut coordinates with bolt and screw rod usually, the structure of existing nut comprises nut body, tapped hole is provided with in nut body, threaded ends on tapped hole and bolt or screw rod cooperatively interacts, in use, easily occurs loosening between nut and bolt or screw rod, affect fastening effect.In the occasion run up and vibrate, nut is very easy to produce and loosens and relative sliding, and cause device damage, serious more likely meets accident.Therefore ensure that this type of nut can tell running with machinery, and don't produce loosening, ensureing mechanical normal operation and safety, is the important technological problems that mechanical producer needs careful attention.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of side pressure point formula locking nut, and structure is simple, and coupling mechanism force is large, effectively solve easily loosen in the situation of vibration, the problem of slippage.
For achieving the above object, the utility model proposes a kind of side pressure point formula locking nut, comprise nut body and flanged surface, described nut body lower end is provided with flanged surface, described nut body and flanged surface are integral type structure, the center of described nut body offers tapped hole, tapped hole runs through the flanged surface of lower end, described tapped hole adopts V thread screw, the side of described nut body is provided with pressure point, described nut body sectional shape is regular hexagon, and the quantity of pressure point is 3, and pressure point is distributed on orthohexagonal three opposite side.
As preferably, the sectional shape of described flanged surface is circular, and the central axis of described tapped hole and the central axis of flanged surface overlap.
As preferably, described flanged surface lower surface is provided with anti-skidding groove, and described anti-skidding groove is circular arc, and the sectional shape of anti-skidding groove is triangle.
As preferably, described pressure point extends inwardly to tapped hole, and the shape of pressure point can be rectangle or circle.
The beneficial effects of the utility model: the utility model structure is simple, easy for installation, by arranging pressure point on the side of nut body, pressure point extends inwardly to tapped hole, destroys original thread form, deformed threads is made to produce locking torque, can effectively solve loosen in the case of vibrations, the problem of slippage, simultaneously by arranging anti-skidding groove on the lower surface of flanged surface, add the frictional force between flanged surface and basal plane, make the pulling force of circumferencial direction larger, not easily produce and get loose.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]

Fig. 3 is the face upwarding assumption diagram of a kind of side of the utility model pressure point formula locking nut.
In figure: 1-nut body, 2-flanged surface, 3-tapped hole, 4-pressure point, the anti-skidding groove of 5-.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of side of the utility model pressure point formula locking nut, comprise nut body 1 and flanged surface 2, described nut body 1 lower end is provided with flanged surface 2, described nut body 1 and flanged surface 2 are integral type structure, the center of described nut body 1 offers tapped hole 3, tapped hole 3 runs through the flanged surface 2 of lower end, described tapped hole 3 adopts V thread screw, the side of described nut body 1 is provided with pressure point 4, described nut body 1 sectional shape is regular hexagon, the quantity of pressure point 4 is 3, pressure point 4 is distributed on orthohexagonal three opposite side, the sectional shape of described flanged surface 2 is circular, the central axis of described tapped hole 3 and the central axis of flanged surface 2 overlap, described flanged surface 2 lower surface is provided with anti-skidding groove 5, described anti-skidding groove 5 is circular arc, the sectional shape of anti-skidding groove 5 is triangle, described pressure point 4 extends inwardly to tapped hole 3, the shape of pressure point 4 can be rectangle or circle.
Utility model works process:
A kind of side of the utility model pressure point formula locking nut in the course of the work, mainly through destroying the original thread form of screw thread, deformed threads is made to produce locking torque, the side of nut body 1 is provided with pressure point 4, pressure point 4 extends inwardly to tapped hole 3, the shape of pressure point 4 can be rectangle or circle, pressure point 4 is distributed on orthohexagonal three opposite side, the effect of pressure point 4 be exactly make bolt tightening go after no longer can back-out, not reciprocally with reusable, there is extremely strong locking torque, effectively can solve and loosen in the case of vibrations, the problem of slippage.Further, nut body 1 and flanged surface 2 are integral type structure, avoid the gap between original nut and pad, flanged surface 2 lower surface is provided with anti-skidding groove 5, and described anti-skidding groove 5 is circular arc, and the sectional shape of anti-skidding groove 5 is triangle, described anti-skidding groove 5 contacts with basal plane, add the frictional force between flanged surface 2 and basal plane, make the pulling force of circumferencial direction larger, not easily produce and get loose.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
