Abstract
A displacement type eccentricity anti-loose standard fastener pertaining to a screw thread standard fastener comprises an anti-loose bolt, an assistant bolt body is positioned below a main bolt body, a screw thread connecting bar is positioned at the middle part of a screw bolt, a spring washer is positioned on the head of the screw thread connecting bar, when the screw thread connecting bar is rotated, the assistant bolt body generates a displacement relatively to the main bolt body and an eccentricity appears on the assistant bolt body; the standard fastener also comprises an anti-loose nut, an assistant nut body is positioned above a main nut body, a spring washer is positioned between the main nut body and the assistant nut body, after the main nut body and the assistant nut body are screwed into a screw bolt, the assistant nut body and the main nut body when being rotated generate a relative displacement and an eccentricity through an eccentricity threaded hole and the screw bolt; under a long-term continuous vibration environment, by using the displacement type eccentricity anti-loose standard fastener, the connection between an anti-loose bolt and a general nut or a threaded hole and the connection between an anti-loose nut and a general screw bolt can be remained relatively stable, a displacement compensation is provided, and the displacement type eccentricity anti-loose standard fastener that can be used repeatedly achieves objects of anti-loose, reduction of cost and elimination of potential safety hazards.
Description
Technical field
The utility model relates to the eccentric locking standard fasteners of a kind of displacement type, belongs to the thread standard fastening piece.
Background technique
Present bolt, nut assembly is widely used in aviation, space flight, railway, steamer, automobile, various device and devices such as bridge, common bolt, though nut is simple in structure, easy to use, but there is easily loosening shortcoming, especially be in for a long time under the environment of continuous shaking at the component that it connected, as easy as rolling off a log at bolt, produce situation about coming off between the nut, really do not reach and connect fastening and locking purpose, cause a serious accident easily, there are many people to invent now and prevent bolt, the way of nut loosening, what use morely is to adopt the elasticity floor clip, or adopts torsion spring that nut can not become flexible, but these floor clips or torsion spring prevent that the effect of nut loosening is limited, be difficult to guarantee bolt under the environment of long-term continuous shaking, nut also can be fastening, overhaul often, replacement cost is big, has potential safety hazard.
Description of drawings
Fig. 1 is the preceding structural representation of chek bolt work in the eccentric locking standard fasteners of a kind of displacement type;
Structural representation when Fig. 2 is chek bolt work in the eccentric locking standard fasteners of a kind of displacement type;
Fig. 3 is the preceding structural representation of lock nut work in the eccentric locking standard fasteners of a kind of displacement type;
Structural representation when Fig. 4 is lock nut work in the eccentric locking standard fasteners of a kind of displacement type.
Among the figure, the 1st, kingbolt body, the 2nd, the secondary body of bolt, the 3rd, threaded rod, the 4th, spring washer, the 5th, mother nut body, the 6th, secondary nut body, the 7th, spring washer.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of displacement type eccentric standard fasteners, guarantees that under the environment of long-term continuous shaking chek bolt or lock nut also can be fastening, prevents to cause a serious accident.
The technological scheme that the utility model adopted is: the eccentric locking standard fasteners of a kind of displacement type, comprise chek bolt, and the below of kingbolt body is provided with the secondary body of bolt, and the bolt middle part is provided with threaded rod, and the head of threaded rod is provided with spring washer; When bolt uses with corresponding nut or tapped hole, rotates above-mentioned threaded rod, the relative kingbolt body of the secondary body of bolt produces displacement, and off-centre appears in the secondary body of bolt; The eccentric locking standard fasteners of displacement type comprises lock nut, and the top of mother nut body is provided with secondary nut body, is provided with spring washer between mother nut body and the secondary nut body; After above-mentioned mother nut body and secondary nut body screwed in bolt, the revolute pair nut body made itself and mother nut body produce relative displacement and off-centre by eccentric threaded bore and bolt.
The utility model has the advantages that under the environment of long-term vibrations continuously, can keep chek bolt and generally nut or tapped hole be connected and lock nut with generally keep relative stability being connected of bolt, bit shift compensation is arranged, can use repeatedly, to reach locking purpose, reduce maintenance, reduce cost, eliminate safe hidden trouble, be difficult for producing major accident.
Embodiment
The eccentric subassembly of lock bolt of a kind of displacement type comprises chek bolt, and the below of kingbolt body 1 is provided with the secondary body of bolt 2, and the bolt middle part is provided with threaded rod 3, and the head of threaded rod 3 is provided with spring washer 4; When chek bolt uses with corresponding nut or tapped hole, rotates above-mentioned threaded rod 3, the secondary body of bolt 2 relative kingbolt bodies 1 produce displacements, the secondary body of bolt 2 appearance off-centre; The eccentric fastener of displacement type comprises lock nut, and the top of mother nut body 5 is provided with secondary nut body 6, is provided with spring 7 between mother nut body 5 and the secondary nut body 6; After above-mentioned mother nut body 5 screwed in bolt with secondary nut body 6, revolute pair nut body 6 made itself and mother nut body 5 produce relative displacement and off-centre by eccentric threaded bore.
Fig. 1 is the state before the chek bolt of the eccentric fastener of a kind of displacement type uses; In Fig. 2, when chek bolt screws in corresponding nut or tapped hole, make threaded rod 3 rotations it drive the secondary body of bolt 2 and enter working state, at this moment, the secondary body of bolt 2 relative kingbolt bodies 1 produce displacement, the secondary body of bolt 2 occurs eccentric, thereby makes chek bolt fastening with corresponding nut or tapped hole, is difficult for loosening; After the secondary body of bolt 2 counterrotatings that screw in nut or tapped hole are resetted, chek bolt can be pulled down from the nut of correspondence or tapped hole.In like manner, (see figure 4) behind the bolt that the mother nut body 5 of lock nut is corresponding with secondary nut body 6 screw-ins, revolute pair nut body 6 makes mother nut 5 produce displacement and off-centre by eccentric threaded bore and bolt, thereby makes lock nut and corresponding bolton; After secondary nut body 6 counterrotatings that screw in bolt are resetted, lock nut can be pulled down from the bolt of correspondence.
The eccentric fastener of a kind of displacement type is under promptly need not the prerequisite of any locking processing under any situation, only select a kind of corresponding with it general bolt or the supporting use of nut for use, can reach locking, fastening effect, chek bolt can directly screw in the tapped hole and use; The eccentric locking standard fasteners of displacement type is bit shift compensation automatically, under the situation of axle power and accuracy of thread reduction, still can obtain good anti-loosing effect, reach promulgated by the ministries or commissions of the Central Government and NBS, working life is consistent with the fatigue strength of material, and can use repeatedly, reduces production costs.
