The tapped through hole of first cylindrical section, the second cylindrical section and the 3rd cylindrical section, the diameter of disk are 1.5 times of positioning section diameter, from
And make to form limited step between positioning section and disk, the first cylindrical section and the second cylindrical section are equal with the diameter of positioning section,
First annular groove is provided between disk and the first cylindrical section, it is recessed that the second annular is provided between the first cylindrical section and the second cylindrical section
Groove, the diameter of first annular groove, the second annular groove and the 3rd cylindrical section is equal, circumference uniform distribution on the outer wall of the first cylindrical section
There are some first strip bulges, some second strip bulges are evenly distributed on the outer wall of the second cylindrical section.
A kind of high stress nut described in the utility model, wherein, first strip bulge and the second strip bulge are equal
It is obliquely installed.
A kind of high stress nut described in the utility model, wherein, first strip bulge and the second strip bulge with
Angle between horizontal plane is 58 °.
A kind of high stress nut described in the utility model, wherein, first strip bulge and the second strip bulge
Cross section is triangular in shape.
A kind of high stress nut described in the utility model, wherein, the bottom edge of second cylindrical section is provided with chamfering
Section.
After above structure, compared with prior art, a kind of high stress nut of the utility model has advantages below：Just
Often in use, positioning section and disk in the utility model are exposed at outside plastic casing, and remaining position need to be embedded in advance
In plastic casing；When mainboard is installed, the stepped hole opened up on mainboard bottom surface is snapped onto on positioning section, limited step is by mainboard
Hold up, play position-limiting action, after mainboard is caught in, through hole on mainboard just with the screwed hole automatic aligning on nut body, this
When be directly threaded into screw, so as on the premise of positioning precision is ensured, realize the rapidly and efficiently assembling of mainboard；This practicality is new
Type is simple in construction, and corresponding operating gets up very convenient；After in the utility model insertion plastic casing, the plastics of fusing can pour into
Into first annular groove, the second annular groove, adjacent first strip bulge and adjacent second strip bulge, after cooling,
First strip bulge and the second strip bulge just considerably increase the contact area with plastic casing, serve good anti-rotation and
Anti-extrusion acts on.
First strip bulge and the second strip bulge are obliquely installed, and anti-rotation and Anti-extrusion effect can be made more preferable.
Angle between first strip bulge and the second strip bulge and horizontal plane is 58 °, can further improve this
The anti-rotation and Anti-extrusion effect of utility model.
The cross section of first strip bulge and the second strip bulge is designed to triangle, is easy to the utility model nut
Production.
Brief description of the drawings
Fig. 1 is a kind of half section structure diagram of high stress nut of the utility model.
Embodiment
A kind of high stress nut of the utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, in this embodiment, a kind of high stress nut of the utility model is included from top to bottom successively
The nut body being made up of positioning section 2, disk 4, the first cylindrical section 6, the second cylindrical section 8 and the 3rd cylindrical section 11, positioning section 2,
Disk 4, the first cylindrical section 6, the second cylindrical section 8 and the coaxial line of the 3rd cylindrical section 11, offer through positioning section on nut body
2nd, the tapped through hole 1 of disk 4, the first cylindrical section 6, the second cylindrical section 8 and the 3rd cylindrical section 11.The diameter of disk 4 is positioning section 2
1.5 times of diameter, so that forming limited step 3 between positioning section 2 and disk 4.First cylindrical section 6 and the second cylindrical section 8 are equal
It is equal with the diameter of positioning section 2, first annular groove 5, the first cylindrical section 6 and second are provided between the cylindrical section 6 of disk 4 and first
Be provided with the second annular groove 12 between cylindrical section 8, first annular groove 5, the second annular groove 12 and the 3rd cylindrical section 11 it is straight
Footpath is equal.It is evenly distributed in some first strip bulges 7 on the outer wall of first cylindrical section 6, circumference on the outer wall of the second cylindrical section 8
