Abstract
The utility model provides a kind of new seven teeth nut, including body, and the one end open of body, body is extended from openend to the other end internal thread, and the side face of body is circumferentially evenly arranged with seven bar shaped teeth, and the end face of bar shaped tooth is arcwall face.Nut of the present utility model uses the reasonable arrangement of seven teeth, adds the contact area of nut and sleeve, reduces tooth depth, it is more uniformly stressed nut, compared with identical six cylindrical teeth nuts, the internal diameter of seven teeth nuts can increase, the product type increase produced.The end face of tooth is cambered surface, increases the bottom contact area of sleeve and nut, is not easy to skid between sleeve and nut.
Description
Technical field
Technical field of fastening is the utility model is related to, especially, is related to a kind of new seven teeth nut.
Background technology
Two kinds of nuts are primarily present on market today, one kind is conventional hexagonal nut, and one kind is common six teeth nut.But
Both nuts, which all exist, significantly uses shortcoming.
For hex nut, due to the diameter of thread and the rigid requirement of nut, the outer-hexagonal of nut can increase, but vapour
The aperture of wheel hub top nut installation is fixed, is so easy for causing to reduce with the sleeve wall thickness that nut coordinates, rigidity becomes
Difference.Easily cause sleeve wall cracking damage during long-term use, product service life reduces.
For six teeth nuts, its external diameter reduces relative to hex nut, adds sleeve wall thickness.But its tooth form lower bottom part
To be U-shaped, to ensure that enough snap-in forces dismantle part, tooth depth is deepened.So as to have problems with:1. because bottom of the tooth portion is U
Type, easily slide during stress, handling nut is inconvenient, also fragile.2. because tooth depth is deeper, meeting sleeve cooperation external diameter
After it is required that, the fertile diameter of thread of institute will be reduced, that is, product type is limited.
Utility model content
Based on this, it is necessary to provide a kind of new seven teeth nut.
The utility model solves its technical problem technical scheme to be taken:A kind of new seven teeth nut, including this
Body, the one end open of the body, the body is extended from openend to the other end internal thread, the side face of the body
Seven bar shaped teeth circumferentially are evenly arranged with, the end face of the bar shaped tooth is arcwall face.
Further, the end face of the bar shaped tooth is same arc surface.
Further, the openend of the body is frustum.
Further, the cone angle of the openend of the body is 60 °.
Further, the screwed hole end set of the body has step.
Further, seven described bar shaped teeth can be also used for screw rod and internal tooth in addition to applying on nut
On nut.
The beneficial effects of the utility model are:Nut of the present utility model uses the reasonable arrangement of seven teeth, adds nut
With the contact area of sleeve, tooth depth is reduced, is more uniformly stressed nut, compared with identical six cylindrical teeth nuts, seven teeth
The internal diameter of nut can increase, the product type increase produced.The end face of tooth is cambered surface, sleeve is contacted with the bottom of nut
Area increases, and is not easy to skid between sleeve and nut.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is A-A diagrammatic cross-sections in Fig. 2.
Parts title and its numbering are respectively in figure:
1. body, 2. internal threads, 3. bar shaped teeth, 4. steps.
Embodiment
The utility model is described in detail presently in connection with accompanying drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
As depicted in figs. 1 and 2, a kind of new seven teeth nut, including body 1, the one end open of body 1, body 1 is from opening
Hold to be extended to the other end and have internal thread 2, the side face of body 1 is circumferentially evenly arranged with seven bar shaped teeth 3, the end of bar shaped tooth 3
Face is arcwall face, and the end face of bar shaped tooth 3 is same arc surface.
The openend of body 1 is frustum, and the cone angle of the openend of body 1 is 60 °.
The screwed hole end set of body 1 has step 4, is used to prevent packing ring in step 4.
Nut of the present utility model uses the reasonable arrangement of seven teeth, adds the contact area of nut and sleeve, reduces
Tooth depth, it is more uniformly stressed nut, compared with identical six cylindrical teeth nuts, the internal diameter of seven teeth nuts can increase, and give birth to
The product type increase of production.The end face of tooth is cambered surface, increases the bottom contact area of sleeve and nut, between sleeve and nut
It is not easy to skid.
In addition, seven described bar shaped teeth can be also used for screw rod and interior teeth nut in addition to applying on nut
On.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work
Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model
Technical scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
