Abstract
The invention provides an anti-loosening fastener component which comprises a bolt and at least two nuts. The nuts are matched with the bolt to limit a workpiece. The nuts is matched with bolts relative to the same side of the workpiece. The nuts includes a lower nut in contact with the workpiece and an upper nut limiting the lower nut. A positioning nut fastener limiting the lower nut is disposed between the two nuts. The positioning nut fastener sleeves the lower nut. The positioning nut fastener comprises a nut cap matched with the corresponding nut and a bent fastener which is connected to the nut cap and used for fastening the edge of the workpiece. The nut cap of the positioning nut fastener sleeves the lower nut matched with the nut cap in size, the short arm of the bent fastener fastens the edge of the corresponding workpiece, and accordingly the nut fastener limit loosening of the lower nut like a fixing wrench. A screw can penetrate a limit hole to be fixed on the workpiece if necessary, the fastened lower nut can be further limited, and loosening can be prevented effectively.
Description
Technical field
The present invention relates to bolt field of fixation devices, refer to especially a kind of Anti-loose fastener assembly.
Background technique
Scyewed joint is the removable connection that utilizes thread part to form, and it is simple in structure, and mounting or dismounting are convenient, are widely used in various machinery.But under shock and vibration or varying load effect, or in high temperature or temperature variation larger in the situation that, the pretightening force in scyewed joint and frictional force can reduce gradually or may instantaneous disappearance, cause connecting and lose efficacy.Once scyewed joint lost efficacy, and by having a strong impact on the normal work of machine, even caused the accident.Therefore,, in the design production process of engineering goods, often can guarantee to connect safe and reliable with nut check mechanism.Modal nut check mechanism is two, axle nut, by two spanner counter-rotatings, two nuts is pushed mutually, realizes powerful locking, and what prevent from connecting gets loose.
But the mode of pairs of anti-loose nut is not absolute stability, in the time of shock and vibration load, frictional force between nut and workpiece may reduce even to disappear, and particularly, in the vibration environment of some high frequency high-amplitude, uses the anti-loose structure of double nut still can get loose.So need to a kind ofly can effectively prevent the fastener assembly coming off under vibration environment.
Summary of the invention
The present invention proposes a kind of Anti-loose fastener assembly, can in the time of shock and vibration load, carry out spacingly to nut, effectively prevents that nut loosening from coming off.
Technological scheme of the present invention is achieved in that a kind of Anti-loose fastener assembly, comprise bolt and coordinate with bolt workpiece is carried out to spacing nut, the nut that described workpiece homonymy relative to bolt coordinates is at least two, comprise the lower nut that contacts with workpiece and the upper cap nut spacing to lower nut, between described two nuts, be provided with one lower nut is carried out to spacing positioning cap button, and positioning cap retaining ring is located on lower nut, described positioning cap button comprises a cap mating with corresponding nut, and of connecting on cap buckles for fastening the curved of workpiece edge.
As preferably, described cap is one end uncovered one end sealing, and uncovered interior shape mates with limited lower nut shape size, and the middle part that cap seals one end has the through hole that allows corresponding bolt pass through.
As preferably, the vertical section of described curved button is L shaped, comprises integrated long-armed and galianconism, on the sidewall of its uncovered one end of long-armed connection cap, and the relatively long-armed overbending direction of galianconism and the opposite direction of cap.
As preferably, in the middle part of the galianconism of described curved button, have one for positioning cap button is fixed on to the spacing hole on workpiece.
As preferably, between described lower nut and workpiece, be provided with damping means, described damping means is rubber washer or spring washer.
As preferably, the curved button segment thickness of described positioning cap button is not less than 3mm.
Compared with prior art, the invention has the advantages that: the cap of positioning cap button is enclosed within on the lower nut mating with its size, the galianconism of curved button fastens the position, edge of corresponding workpiece, positioning cap button is as same back-up wrench like this, the pine of having limited lower nut moves back, necessary time, re-use screw and be fixed on workpiece through spacing hole, fastening lower nut is carried out further spacing, effectively prevent from becoming flexible.Upper cap nut fixes from top to positioning cap button again, and positioning cap button plays the effect that is equivalent to a spring pad for upper cap nut.
