Abstract
The utility model discloses a cover -shaped nut, including the nut body, the nut body includes connecting portion and operating portion, be equipped with the screw thread district in the connecting portion, the operating portion terminal surface is equipped with the recess of straight line groove or cross recess, connecting portion with adjacent first cambered surface and the second cambered surface of being equipped with in operating portion junction, be equipped with the spanner position on the operating portion excircle. Through adopting above -mentioned scheme, when using the nut to connect, the setting of first cambered surface and second cambered surface for nut body outward appearance is the curved surface, picks shi buhui and leads to the fact the fish tail to the user, has still reduced the stress of connecting portion and operating portion junction, has improved the holistic intensity of nut, the setting of the recess of straight line groove or cross recess and set up the spanner position on the operating portion excircle after, increased multiple screwed nut's way, it is more convenient to use.
Description
Technical field
This utility model is related to machanical fastener field, particularly to a kind of acorn nut.
Background technology
Nut is exactly nut, is threaded together the part for playing the role of fastening with bolt or screw rod.
Nut according to the different nuts that divide into a lot of different shapes and different materials using field, acorn nut is exactly
One of which nut.Standard acorn nut is as shown in figure 3, include threaded joints 14 and capping 15, described acorn nut
Can be tightened by spanner when connecting, dismounting is more limited to.
Utility model content
The purpose of this utility model is to provide a kind of acorn nut that can be tightened with multiple types of tools.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of acorn nut, including nut body, described nut body includes connecting portion and operating portion, in described connecting portion
It is provided with threaded area, described operation end surface is provided with flat recess or cross recess groove, described connecting portion and described operating portion junction
Adjacent be provided with the first cambered surface and the second cambered surface, described operating portion is cylindrical to be provided with spanner position.
By adopting such scheme, when being attached using nut, the setting of the first cambered surface and the second cambered surface is so that spiral shell
Maternal external table is in curved surface, user will not be caused to scratch during crawl, and also reduce connecting portion and operating portion junction should
Power, improves the overall intensity of nut.The setting of flat recess or cross recessed groove and on operating portion is cylindrical arrange spanner
Behind position, increased the approach of multiple nuttings, using convenient.
As a kind of improvement of the present utility model, the described bottom of thread leaves gap.
By adopting such scheme, when nut is connected with part, the debris between some screw threads can be extruded into gap
Go out, be is threaded more accurate, improves threaded intensity.
As a kind of improvement of the present utility model, described connection end surface is provided with boss.
By adopting such scheme, the setting of boss make nut with need the part threadeded between contact area
Reduce, prevent joint face injustice from leading to connection effect bad, when connecting can with step on setting plain washer so that nut even
Connect is more firm.
As a kind of improvement of the present utility model, described boss face is provided with the first chamfering.
By adopting such scheme, after boss face arranges the first chamfering, acute angle, the hair of original processing can be removed
Thorn etc. so that user will not be caused when nut is crawled scratch,
As a kind of improvement of the present utility model, described operation end surface is provided with the second chamfering.
By adopting such scheme, after operating portion arranges the second chamfering, acute angle, the hair of original processing can be removed
Thorn etc., can prevent user from should rotate nut and cause to scratch.
As a kind of improvement of the present utility model, described second chamfering is 45 ° -60 ° with described operating portion axial direction angle.
By adopting such scheme, the setting of the angle of inclination of the second chamfering on operating portion more reasonable, can be effectively anti-
Only user is scratched the design more science so that nut.
As a kind of improvement of the present utility model, described operating portion outer round surface is provided with annular knurl.
By adopting such scheme, after operating portion outer fringe surface setting annular knurl, user energy when rotating nut by hand
Effectively prevent nut from sliding so that rotating nut enhanced convenience.
In sum, this utility model has the advantages that：
1st, pass through to arrange the first cambered surface, the second cambered surface, the first chamfering and the second chamfering outside nut body, eliminate spiral shell
The defects such as acute angle that matrix face is produced by original processing, burr so that nut body appearance is in curved surface, thus when nut is crawled
User will not be caused to scratch；Also reduce connecting portion and the stress of operating portion junction, improve the overall intensity of nut.
2nd, pass through to arrange flat recess or cross recessed groove in operation end surface, and annular knurl is set in operating portion outer round surface
With spanner position so that user when tightening by hand can anti-sliding stop, tightening of nut can also be carried out using multiple types of tools,
Make the application of nut more extensive.

Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment one：
In conjunction with Fig. 1 and Fig. 2, a kind of acorn nut, including nut body 1, described nut body 1 includes connecting portion 2, connects
It is provided with threaded area 4, gap 9 is left in threaded area 4 end, the end face of connecting portion 2 is additionally provided with boss 10, the end face of boss 10 in portion 2
It is additionally provided with the first chamfering 11.
The axially extending place of connecting portion 2 is connected with operating portion 3, connecting portion 2 and operating portion 3 junction is adjacent is provided with the first arc
Face 6 and the second cambered surface 7, operating portion 3 end face is provided with the groove 5 of flat recess, and operating portion 3 end face is additionally provided with the second chamfering 12, the
