Abstract
The utility model relates to a novel swivel nut formula locking locknut, including nut body, the nut body upper end is inside to be equipped with wire thread insert, and wire thread insert is formed by nonrust steel wire or other wire coilings. The great circle of wire thread insert upper end be the anchor circle, and the end of anchor circle is equipped with a crotch on wire thread insert, and on wire thread insert's the ditch inslot position corresponding with the crotch is inlayed to the nut body upper end, bore have one with the big or small the same nut body aperture of the used wire diameter of wire thread insert, insert the crotch in the nut body aperture. The utility model has the advantages of under the exogenic action, also can not producing relatively between nut body and the wire thread insert, the pine changes to the long -term frictional resistance who keeps the screw thread to produce between vice lastingly is reliable and stable, connects locking shock -resistant mesh with locking function of locking and the screw fastening who realizes the nut.
Description
Technical field
The utility model relates to a kind of detachable screw threads for fastening connection set, particularly a kind of Novel spiral shell type locking lock nut.
Background technique
Existing spiral type locking lock nut is compared with locking nut for non-metal inserts with other full-metallic locking nut, although there is locking torque reliable, strong to the adaptation of bolt tolerance, reusability is good, the advantage such as turn round-establish unprincipled connection reasonably stability and application range of products is wide.But, due to its structure, also also exist because nut body and steel-wire screw-socket are riveted not tight, cause some technical problems that nut anti-looseness hydraulic performance decline or anti-loosening property completely lose.
As everyone knows, the part of any product, in mechanical processing process, always to produce certain machining error.Spiral type locking lock nut is the same with other products, and part produces certain machining error and also can hardly be avoided in course of working.Due to the existence of these errors, the spiral type locking lock nut after assembling riveted joint, will produce nut body and steel-wire screw-socket and rivet the phenomenon that degree of tightness differs.
Rivet tight nut, its anti-loosing effect is no doubt fine.But the nut that those riveted joints are not tight, under the effect of external force, will produce relative pine and turn between nut body with steel-wire screw-socket.This pine relatively turns, and the surface friction drag between screw pair can be made to reduce.The function that the reduction of surface friction drag makes again the locking of nut locking reduces.Under the effect of variable load, vibration and impulsive load, the vibration cycles of ten million time run out of the locking surface friction drag be threaded, it is made to change into loosening from trickle pine, and then nut is got loose cause the inefficacy be threaded, cause machine or equipment cisco unity malfunction, serious also can cause unnecessary accident.
summary of the invention:
The purpose of this utility model is to overcome above deficiency, provides that a kind of structure is simple, cost is low, the reliable a kind of Novel spiral shell type locking lock nut of safety and stability.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel spiral shell type locking lock nut, comprise nut body, inside, described nut body upper end is provided with steel-wire screw-socket, the great circle of described steel-wire screw-socket upper end is anchoring ring, a crotch is provided with at the end of described steel-wire screw-socket anchoring ring, and inlay on position corresponding with described crotch in the groove of steel-wire screw-socket in inside, described nut body upper end, be drilled with a nut body aperture identical with described steel-wire screw-socket steel wire diameter used size, described crotch inserts in described nut body aperture.
Further improvement of the utility model is: described steel-wire screw-socket is formed by Stainless Steel Wire or other wire coiling.
The utility model compared with prior art has the following advantages:
1, a crotch is increased at the end of the steel-wire screw-socket anchoring ring of Stainless Steel Wire or other wire coiling; Inlay on the relevant position in the groove of steel-wire screw-socket in nut body upper end simultaneously, bore a nut body aperture identical with steel-wire screw-socket steel wire diameter used size, during assembling product, in advance the crotch of steel-wire screw-socket anchoring ring end is inserted in nut body aperture, and then rivet.After riveted joint, steel-wire screw-socket terminal hook hooks nut body tightly.Even if so under external force, also can not produce relative pine between nut body with steel-wire screw-socket and turn, thus the surface friction drag produced between maintenance screw pair is reliable and stable, to realize the locking locking functions of nut and to make the object of screw threads for fastening connection anti-loose antidetonation.
2, the utility model structure is simple, low cost of manufacture, and homogeneity of product is strong, be convenient to implement, fully demonstrated the locking torque reliability of spiral type locking lock nut, to the strong adaptability of bolt tolerance, reusability is good, turns round the technical characteristics of reasonably stability of establishing unprincipled connection.
accompanying drawing illustrates:
Fig. 1 is plan view of the present utility model;
Fig. 2 is the utility model A-A sectional view;
Fig. 3 is the utility model B-B sectional view;
Number in the figure: 1-nut body, 2-steel-wire screw-socket, 3-nut body aperture, 4-crotch.
embodiment:
In order to deepen understanding of the present utility model, below we will the utility model is described in further detail by reference to the accompanying drawings, this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1-3 shows a kind of mode of execution of a kind of Novel spiral of the utility model shell type locking lock nut, increase a crotch 4 at the end of steel-wire screw-socket 2 anchoring ring of Stainless Steel Wire or other wire coiling; Inlay on the relevant position in the groove of steel-wire screw-socket 2 in nut body 1 upper end simultaneously, bore a nut body aperture 3 identical with steel-wire screw-socket steel wire diameter used size, during assembling product, in advance the crotch 4 of steel-wire screw-socket anchoring ring end is inserted in nut body aperture 3, and then rivet.
Product is after assembling, riveted joint, and the crotch 4 of steel-wire screw-socket 2 anchoring ring end hooks nut body 1 tightly.When bolt screws in after nut, steel-wire screw-socket relies on the elastic force of self to be closely fitted in the alveolus of bolt thread, even if under the effect of variable load, vibration and impulsive load, also can not produce relative pine and turn between nut body 1 with steel-wire screw-socket 2.Thus the surface friction drag produced between maintenance screw pair is reliable and stable, achieve the locking locking functions of nut well, the pretightening force that screw threads for fastening is linked is kept for a long time enduringly, finally realizes screw threads for fastening link shock-proof check object.
The foregoing is only and mode of execution of the present utility model is described; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
