Abstract
The utility model discloses a mutually stop check washer, comprising at least two washer bodies; the adjacent washer bodies are connected upward into a whole through a connecting piece on a horizontal axle, each washer body is symmetrically connected with a couple of bending fins on the upward excircle of a vertical axle, and the joint between two side edges of each bending fin and the washer body is respectively provided with a circular arc-shaped groove. When the mutually stop check washer is used, the washer body is sheathed with a screw bolt, and a nut is mounted and screwed; when the nut is screwed to the end, the six lateral faces of the nut are adjusted, the linear bending fins are bended upward, and the bending fins are respectively closed to both sides of the nut. The screw bolt and the nut generate relative motion owing to the exterior vibrating action, the rigidity of the bending fins of the mutually stop check washer prevents the relative motion of the screw bolt and the nut. The mutually stop check washer of the utility model has reliable performance, low cost and easy mounting and use; the mutually stop check washer is suitable for the rail transportation system and the electric power contact screen.
Description
Technical field
The utility model relates to fastening and fixed component, particularly a kind of locking mutually stop pad.
Background technique
In the China Railway system, having what lean between many members is that screw pair is connected and fixed, common screw pair connection is made of screw bolt and nut, but because the member of the railway system can be subjected to continuous frequent oscillating action when work, cause between nut in the screw pair and the bolt usually loosening, to such an extent as to cause nut to come off, bring great hidden danger for the traffic safety of rail transportation system.In the time of in particular for the electric power contact net, the axial force that screw pair connects is little, connects not tightly, causes electric conductivity bad, down to the generating electrodes burning accident.Once adopted locking mutually stop measures such as special nut in the past, and for example became the thread form nut, but Yin Qiyi comes off and causes using effect not good.
The model utility content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of locking mutually stop reliable performance, cost is low and locking mutually stop pad easy to install, that be applicable to rail transportation system and electric power contact net.
A kind of locking mutually stop pad of the utility model, comprise lamellar body, lamellar body is at least 2, on horizontal axis, be connected as a single entity between the lamellar body that faces mutually by connecting sheet, the cylindrical symmetry that each lamellar body makes progress in pivotal axis is connected with a pair of bent fin, and the centre distance of facing lamellar body mutually is 25mm～35mm.
The locking mutually stop pad of the utility model, wherein two of each bent fin sides and lamellar body connection are respectively equipped with circular groove, and the radius of groove is 1.25mm.
The locking mutually stop pad of the utility model, the quantity of its median plate body is 2～6.
The locking mutually stop pad of the utility model, the quantity of its median plate body is 2, the centre distance of facing lamellar body mutually is 28mm or 31mm.
The locking mutually stop pad of the utility model, the quantity of its median plate body is 3, the centre distance of facing lamellar body mutually is 26mm.
The locking mutually stop pad of the utility model, wherein the thickness of fin and connecting sheet is respectively 1mm～4mm.
The locking mutually stop pad of the utility model, its median plate body and bent fin adopt Austenitic Stainless Steel to make.
The locking mutually stop pad of the utility model, wherein the diameter of through hole is 10 or 12mm.
Locking mutually stop pad of the present utility model has the following advantages:
1, broken through the limitation that nut anti-looseness stop can only be tried every possible means on this body structure of screw pair, utilize the stability of screw pair institute connector element and the interaction between a plurality of bolts, member and a plurality of bolt and locking mutually stop pad are connected as a single entity, as long as pad does not damage, nut is loosening never.
2, because the nut external form mostly is hexagonal shaped greatly, this locking mutually stop pad can guarantee that a pair of bent fin overlaps with a side of nut, guarantees that the Tightening moment of nut does not change.Simultaneously, can be according to the pad of the multiple different size of specifications design of " U " shape bolt for use.
3, locking mutually stop test shows, owing to adopted the mode of mechanical connection, adopts this locking mutually stop pad can accomplish permanent locking stop.
4, locking mutually stop pad is easy for installation, does not need special equipment, can finish with instruments such as common pliers, screwdrivers.
5, the locking stop form that adopts usually is that flat gasket adds compression spring, if with this locking mutually stop pad, can replace plural monomer pad, cost will reduce.
Below in conjunction with accompanying drawing locking mutually stop pad of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the locking mutually stop pad of 2 lamellar bodies;
Fig. 2 is the structural representation that the utlity model has the locking mutually stop pad of 3 lamellar bodies.
Embodiment
See figures.1.and.2, the locking mutually stop pad of the utility model comprises lamellar body 1, and lamellar body 1 has through hole 2, and the diameter of through hole 2 is 10～12mm.Lamellar body 1 is at least 2, its quantity can be 2～6, the external diameter of its cylindrical and bolt head or nut is corresponding, is connected as a single entity by connecting sheet 5 on horizontal axis between the lamellar body 1 that faces mutually, and the cylindrical symmetry that each lamellar body 1 makes progress in pivotal axis is connected with a pair of bent fin 3.The thickness of fin 3 and connecting sheet 5 is respectively 1mm～4mm.The centre distance of facing lamellar body 1 mutually is 25mm～35mm.
Be respectively equipped with groove 4 at 3 two sides of each bent fin and lamellar body 1 connection, the radius of groove 4 is 1.25mm.Groove 4 be set be for the ease of from groove 4 with bent fin 3 bendings, make on its side that is attached to nut or the adjacent component.
Lamellar body 1, connecting sheet 5 and bent fin 3 adopt Austenitic Stainless Steel to make.The employing Austenitic Stainless Steel is made, and has the high characteristics of corrosion protection, intensity and toughness, is highly suitable for so open-air working environment such as the railway system.
With reference to Fig. 1, in the embodiment who the utlity model has 2 lamellar bodies, the centre distance of facing lamellar body 1 mutually is 28mm or 31mm.
With reference to Fig. 2, in the embodiment who the utlity model has 2 lamellar bodies, the quantity of lamellar body 1 is 3, and the centre distance of facing lamellar body 1 mutually is respectively 26mm.
The locking mutually stop pad of the utility model in use, can earlier lamellar body 1 cover be installed on the bolt, refill and fastening nut, tighten to when last, adjust six sides of nut, make that wherein two sides are relative with the plate face of bent fin 3, then bent fin 3 is upwards bent, it is pasted mutually with two sides of nut respectively.When bolts and nuts produced relative movement owing to extraneous oscillating action, the rigidity of the bent fin 3 of locking mutually stop pad will stop the relative movement between the bolts and nuts.
