Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly the technical field of a kind of pair of flange combination formula nut.
[background technique]
Nuts and bolt is requisite fastening piece in machinery, and nuts and bolt is easy for installation, fixing reliable, and nuts and bolt is made of metal usually, and the nuts and bolt that uses at the special occasions such as electrical insulation or corrosion protection also has various non-metallic material.Wherein hexagon head is the most frequently used.General countersunk head is used in and requires to connect the smooth place not having projection, rear surface, because countersunk head may be screwed in part.Round end also can be screwed in part.The screwing force of square toes can more greatly, but size is very large.This bolt is conducive to the connection by variable force.Steel structure has special high-strength bolt, head can do bigger, and size also changes.Nut have a flanged surface with non-flanged surface, the nut of flanged surface do not need with pad with the use of, the needs of non-flanged surface and pad with the use of, install complicated, be unfavorable for increasing work efficiency, a lot of factory all can as far as possible by nut unified specification, but some parts needs often dismounting, so be not suitable for flange nut, so factory often uses multiple nut, parts are caused to extrude, raise manufacture cost, installation process is easily made mistakes simultaneously, be unfavorable for raising the efficiency faster, for some special equipments, need to fix with multiple nut, traditional flange nut can not use simultaneously.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of two flange combination formula nut is proposed, the fastening effect of plain nut can be realized by different combinations, also can realize the fastening effect of flange nut and the fastening effect of two flange nut, can be good at the kind reducing factory's buying component, be conducive to cost-saving, simultaneously fixing reliable, be not easy to come off, the uniformity of nut can be improved, improve device assembles efficiency.
For achieving the above object, the utility model proposes a kind of two flange combination formula nut, comprise flange circle and nut, described flange circle is separately positioned on the both sides of nut, screw is provided with in the middle of described nut, screw thread is provided with in described screw, nut sidepiece is provided with fixed hole, trepanning is provided with in the middle of described flange circle, flange circle both sides are respectively arranged with anticreep face and junction surface, described junction surface is provided with some connecting rods, and the thickness of described flange circle is 2.1 ~ 3mm, and the quantity of described connecting rod is 4 ~ 6.
As preferably, described connecting rod is arranged in fixed hole, and the diameter of described fixed hole is 2.5 ~ 4mm.
As preferably, the quantity of described connecting rod is 5, and the quantity of connecting rod is identical with the quantity of fixed hole.
As preferably, described anticreep face is provided with projection, and described projection is hemisphere.
As preferably, the thickness of described flange circle is 2.5mm.
The beneficial effects of the utility model: the utility model is by being applied in nut by flange circle and nut, the fastening effect of plain nut can be realized by different combinations, also the fastening effect of flange nut and the fastening effect of two flange nut can be realized, can be good at the kind reducing factory's buying component, be conducive to cost-saving, simultaneously fixing reliable, be not easy to come off, the uniformity of nut can be improved, improve device assembles efficiency.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
