Utility model content
The technical problems to be solved in the utility model be in order to the prior art is overcome to tighten the sleeve of nut with nut because
Dimensional discrepancy so that sleeve discontinuity occurs when tightening nut to bolt, is easily provided the defects of damage screw thread a kind of
Nut.
The utility model is to solve above-mentioned technical problem by following technical proposals：
A kind of nut, the nut include：
Turn-knob portion, the cross section of the turn-knob portion is polygon；
Auxiliary section, the upper surface of the auxiliary section abut the turn-knob portion lower face, and the auxiliary section is from the turn-knob portion
Lower face extend along the length direction of the turn-knob portion towards away from the direction of the turn-knob portion, the outer surface of the auxiliary section from
Tiltedly extend outwardly on the direction of one end of the knob to one end of the separate knob.
Preferably, the cross section of the turn-knob portion is hexagon.
Preferably, the turn-knob portion length direction and from the lower face of the turn-knob portion towards away from the turn-knob portion
On direction, the outer diameter of the auxiliary section gradually increases.
Preferably, the outer surface of the auxiliary section is annular round table surface shape.
Preferably, the nut further includes connecting portion, the upper surface of the connecting portion abuts the lower face of the auxiliary section,
Short transverse of the connecting portion from the lower face of the auxiliary section along the auxiliary section is prolonged towards the direction away from the auxiliary section
It stretches.
Preferably, the outer surface of the connecting portion is cylindrical surface.
Preferably, the nut has a through-hole, the through-hole is through the whole thickness direction of the knob and prolongs
The lower face for deviating from the connecting portion in the connecting portion is extended to, the through-hole includes the threaded portion axially set gradually along it
And targeting part, the targeting part is located in the connecting portion, and one end of the targeting part is adjacent to the threaded portion
Point, the other end extends to the lower face of the connecting portion.
Preferably, the targeting part has ring screw guide surface, the ring screw guide surface extends the company
The entire circumferential direction of socket part, and extend in the diagonal from the lower end of the connecting portion towards the upper surface of the connecting portion.
The positive effect of the utility model is：
The utility model is by setting annular round table surface auxiliary section, because its annular round table surface is closely matched with sleeve lower edge
It closes, construction sleeve can be accurately positioned so that when tightening nut and bolt, nut and bolt all uniform stresseds can be made, avoided
Bolt damaged screw due to unbalance stress.Meanwhile because connection lower edge area is suitable with washer area, and flatness pole
It is good, using this nut, the use of washer can be removed from, be conducive to cost-effective.

Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but be not therefore limited in the utility model
Among the embodiment described range.
The present embodiment provides a kind of nut, as shown in Figure 1, nut includes turn-knob portion 1 and auxiliary section 2.
Upper surface adjoining turn-knob portion 1 lower face of auxiliary section 2, auxiliary section 2 is from the lower face of turn-knob portion 1 along turn-knob portion 1
Length direction extends towards away from the direction of turn-knob portion 1, and the outer surface of auxiliary section 2 is from close to one end of knob to separate knob
One end direction on tiltedly extend outwardly.
More specifically, on the length direction of turn-knob portion 1 and the direction from the lower face of turn-knob portion 1 court away from turn-knob portion 1,
The outer diameter of auxiliary section 2 gradually increases.
More specifically, the outer surface of auxiliary section 2 is annular round table surface shape.
The present embodiment is by setting the auxiliary section 2 of annular round table surface shape, because its annular round table surface and sleeve lower edge are tight
Close fit can be accurately positioned construction sleeve so that when tightening nut and bolt, nut and bolt all uniform stresseds can be made,
Avoid bolt damaged screw due to unbalance stress.
As shown in Figure 1, nut further includes connecting portion 3, the lower face of the upper surface adjoining auxiliary section 2 of connecting portion 3, connecting portion
3 short transverse from the lower face of auxiliary section 2 along auxiliary section 2 extends towards away from the direction of auxiliary section 2.It can understand with reference to Fig. 3.
More specifically, the outer surface of connecting portion 3 is cylindrical surface.
Because connection lower edge area is suitable with washer area, and flatness is fabulous, using this nut, can remove pad from
The use of circle is conducive to cost-effective.
As shown in Fig. 2, nut has a through-hole 4, through-hole 4 is through the whole thickness direction of knob 1 and the company of extending to
Deviating from the lower face of connecting portion 3 in socket part 3, through-hole 4 includes the threaded portion 41 axially set gradually along it and targeting part 42,
Targeting part 42 is located in connecting portion 3, and one end of targeting part 42 is adjacent to threaded portion 41, and the other end extends to connecting portion
3 lower face.
More specifically, targeting part 42 has ring screw guide surface 421, ring screw guide surface 421 extends connection
The entire circumferential direction in portion 3, and extend in the diagonal from the lower end of connecting portion 3 towards the upper surface of connecting portion 3.
Ring screw guide surface is conducive to nut and plays a guiding role when being bolted so that nut is more suitable with bolt
It screws sharply, further ensures that screw thread uniform force is indeformable.
