Abstract
The utility model discloses an extension hexagonal coupling nut, including nut body and ring flange, the cross sectional shape of nut body is regular hexagon, the cross sectional shape of ring flange is circular, the ring flange is located the below of nut body, nut body and ring flange formula structure as an organic whole, nut body and ring flange center department are provided with coaxial screw hole with the aperture, the upper end and the lower extreme of screw hole all are equipped with chamfer I, be equipped with the screw through -hole that is used for locking on the ring flange. The utility model discloses a thicken the axial thickness of nut body to the extended flight lead of screw hole has improved the power of screwing up between nut and screw rod or the bolt, through set up 3 screw through -holes on the ring flange, has ensured that the nut can move along with mechanical equipment, and don't can produce the pine and take off, compares with prior art, and the stable in structure of this kind of nut lockingly takes off effectually, and the security performance is high.
Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of technical field of hexagon nut.
[background technique]
Nut a kind ofly very common is fastenedly connected parts, is widely used in the connection of various mechanical device.But setter is often difficult to determine that whether nut is fastening and puts in place in actual use, be therefore difficult to guarantee when using for a long time, bolt and nut can not loosen automatically.And in some cases, the loosening of nut, coming off to cause serious accident, causes heavy economic losses.Nut coordinates with bolt and screw rod usually, the structure of existing nut comprises nut body, in nut body, be provided with tapped hole, and the threaded ends on tapped hole and bolt or screw rod cooperatively interacts, in use, easily occurs loosening between nut and bolt or screw rod, affect fastening effect, in prior art, in the occasion running up and be hit and vibrate, nut is very easy to produce and loosens and relative sliding, and cause device damage, serious more likely meets accident.Therefore ensure that this type of nut can tell running with machinery, and don't produce loosening, ensureing mechanical normal operation and safety, is the important technological problems that mechanical producer needs careful attention.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, and propose a kind of lengthening hexagon connecting nut, can be applicable to vibrated and impact in large machinery, structural stability, anti-loose effective, Safety performance is high.
For achieving the above object, the utility model proposes a kind of lengthening hexagon connecting nut, comprise nut body and flange plate, the sectional shape of described nut body is regular hexagon, the sectional shape of described flange plate is circular, described flange plate is positioned at the below of nut body, nut body and flange plate are integral type structure, described nut body and flange plate center are provided with coaxially with the tapped hole in aperture, the top and bottom of described tapped hole are equipped with chamfering I, and described flange plate is provided with the screwing through hole for locking.
As preferably, described flange plate upper surface is provided with rounding, and described nut body upper surface is provided with chamfering II.
As preferably, the quantity of described screwing through hole is 3, and the spacing between 3 screwing through hole is equal between two.
As preferably, the section area of described nut body is less than the section area of flange plate, and the axial height of described nut body is 1.5 ~ 2 times of nut body radial width.
The beneficial effects of the utility model: the utility model is by thickening the axial thickness of nut body, thus increase the lead of screw thread of tapped hole, improve the screwing force between nut and screw rod or bolt, by offering 3 screwing through hole on flange plate, attachment screw pins flange plate, flange plate and nut body are integral type structure, thus ensured that nut can move with machinery, and don't can produce and get loose, compared with prior art, the structural stability of this nut, anti-loose effective, Safety performance is high.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is a kind of plan structure figure lengthening hexagon connecting nut of the utility model;
Fig. 2 is a kind of main pseudosection lengthening hexagon connecting nut of the utility model.
In figure: 1-nut body, 2-tapped hole, 3-flange plate, 4-rounding, 5-chamfering I, 6-chamfering II, 7-screwing through hole.
[embodiment]
Consult Fig. 1, Fig. 2, the utility model one lengthens hexagon connecting nut, comprise nut body 1 and flange plate 3, the sectional shape of described nut body 1 is regular hexagon, the sectional shape of described flange plate 3 is circular, described flange plate 3 is positioned at the below of nut body 1, nut body 1 and flange plate 3 are integral type structure, described nut body 1 and flange plate 3 center are provided with coaxially with the tapped hole 2 in aperture, the top and bottom of described tapped hole 2 are equipped with chamfering I5, described flange plate 3 is provided with the screwing through hole 7 for locking, described flange plate 2 upper surface is provided with rounding 4, described nut body 1 upper surface is provided with chamfering II6, the quantity of described screwing through hole 7 is 3, spacing between 3 screwing through hole 7 is equal between two, the section area of described nut body 1 is less than the section area of flange plate 3, the axial height of described nut body 1 is 1.5 ~ 2 times of nut body 1 radial width.
Utility model works process:
The utility model one lengthens hexagon connecting nut in the course of the work, by the axial height of nut body 1 being set to 1.5 times of nut body 1 radial width, compare general nut, thickness promotes greatly, therefore the lead of screw thread of tapped hole 2 have also been obtained lengthening, the screw rod coordinated with it or the reach of bolt engaging portions also elongated, improve the screwing force between nut and screw rod or bolt, nut not easily got loose when being subject to general vibration or impacting.In addition, flange plate 3 is provided with the screwing through hole 7 for locking, the quantity of screwing through hole 7 is 3,3 screwing through hole form an equilateral triangle, during installation, when a certain parts of fastening nuts are in the machinery at place, the basal plane contacted with flanged surface 3 has been offered 3 corresponding fixed holes in advance, with screw through the screwing through hole 7 on flange plate 3, and screw is fixed in 3 fixed holes of basal plane, this means of fixation, has ensured that nut can move with machinery, and don't can produce loosening.In addition, flange plate 2 upper surface is provided with rounding 4, the top and bottom of tapped hole 2 are equipped with chamfering I5, nut body 1 upper surface is provided with chamfering II6, the setting of rounding 4 makes flange plate axially have certain radian, add the ability of its bearing load, arranging of chamfering can reduce surperficial burr, makes appearance more attractive in appearance.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
