Abstract

The invention relates to a nut, which comprises a nut body, an annular sheath and a bore, wherein the annular sheath is integrated with the nut body, and the bore with an internal thread runs through the nut body and the annular sheath. The nut is characterized in that: the cross sections of both ends of the nut body are annular, the cross section of the middle part of the nut body is a quadrangle with a hole in the middle, which is formed by an upper outwardly raised arc, a lower outwardly raised arc, a left straight line and a right straight line, the left straight line and the right straight line are in parallel, and the axial length of the annular sheath is greater than the axial thickness of the nut body. The nut has the advantages that: since the middle part of the nut is not wide, the nut cannot interfere with a neighboring mechanism in the process of motion, so that the mechanism can be prevented from being stuck, and the shifting friction between connected parts is prevented from occuring, so that the abrasion of the connected parts can be effectively avoided.

Description

Nut
Technical field
The present invention relates to a kind of threaded connector, relate in particular to a kind of nut.
Background technique
Nut is a kind of part that can machinery closely be coupled together; It usually and bolt be used the purpose that reaches fastening component; Promptly, bolt connected the through hole that component are provided with through being penetrated; Come component are carried out the other end attaching nut of bolt fastening owing to above-mentionedly connected the external diameter that through hole internal diameter that component are provided with all can be slightly larger than the bolt screw rod usually, therefore; Connected component issue the looks friction that misplaces mutually through regular meeting in vibration, thereby are caused certain wearing and tearing to connecting component.
Summary of the invention
The purpose of this invention is to provide a kind of nut.
The technological scheme that the present invention adopts is:
Nut; Comprise nut body, be holistic ring jacket and run through nut body and ring jacket has the boring of internal thread with nut body; The shape of cross section at the two ends of said nut body is an annular; The centre quadrilateral with holes that the straight line that the cross section of said nut body intermediate portion is parallel to each other for the arc that outwards protruded by upside and downside and left side and right side surrounds, the axial length of said ring jacket is greater than the axial thickness of said nut body.
The material of said nut is a copper.
The length of said nut body intermediate portion is greater than the length of nut end.
Be provided with chamfering a between the section that said ring jacket is not connected with nut body and the outer circumferential walls of ring jacket.
Be provided with chamfering b between the section that said ring jacket is not connected with nut body and the circumferential inner wall of ring jacket.
Advantage of the present invention is: avoided because nut intermediate portion size is wide; Cause in moving process and interfere with adjacent mechanism; Avoid mechanism blockage, prevented to be connected the dislocation friction takes place between the component, thereby effectively avoided being connected the wearing and tearing of component.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a plan view of the present invention.
Wherein: 1, nut body, 2, boring, 3, ring jacket, 4, internal thread, 5, chamfering a, 6, chamfering b.
Embodiment
As illustrated in fig. 1 and 2; Nut of the present invention comprise nut body 1, with nut body 1 for holistic ring jacket 3 with run through nut body 1 and ring jacket 3 has the boring 2 of internal thread 4;, the material of nut is a copper, the shape of cross section at the two ends of nut body 1 is an annular; The centre quadrilateral with holes that the straight line that the cross section of nut body 1 intermediate portion is parallel to each other for the arc that outwards protruded by upside and downside and left side and right side surrounds; The length of nut body 1 intermediate portion is greater than the length of nut end, and the axial length of ring jacket 3 is provided with chamfering a5 greater than the axial thickness of said nut body 1 between the section that ring jacket 3 is not connected with nut body 1 and the outer circumferential walls of ring jacket; Be provided with chamfering b6 between the section that ring jacket 3 is not connected with nut body 1 and the circumferential inner wall of ring jacket; Avoided causing in moving process to interfere, avoided mechanism blockage with adjacent mechanism because nut intermediate portion size is wide; Prevent to be connected the dislocation friction takes place between the component, thereby effectively avoid being connected the wearing and tearing of component.

Claims (5)

1. nut; Comprise nut body, be holistic ring jacket and run through nut body and ring jacket has the boring of internal thread with nut body; The shape of cross section that it is characterized in that the two ends of said nut body is annular; The centre quadrilateral with holes that the straight line that the cross section of said nut body intermediate portion is parallel to each other for the arc that outwards protruded by upside and downside and left side and right side surrounds, the axial length of said ring jacket is greater than the axial thickness of said nut body.
2. nut according to claim 1, the material that it is characterized in that said nut is a copper.
