Abstract
The invention discloses a structure of a strong locking nut, relating to a structural technology of a mechanical standard component. The head part of the locking nut is provided with a flange; a counter bore is formed inwardly at a flange end; a plurality of gaps are uniformly distributed on the edge part of the counter bore; the periphery of a gasket is provided with protruding bosses; the quantity of the bosses and the arrangement in the circumferential direction are accordant with the gaps on the edge of the counter bore of the locking nut; the bosses can be just clamped in the gaps on the edge of the counter bore; a through hole is formed in the middle of the gasket; and a plurality of upwardly-warping brake ratchets are uniformly distributed around the edge of the through hole. When the structure is in use, the gasket is arranged inside the counter bore of the locking nut, the brake ratchets are positioned outside, the bosses are clamped in the gaps, the brake ratchets are pressed towards a fastened part after the locking nut is screwed, and the locking nut, the gasket and a connected piece are integrated tightly under the action of elastic force, so that the anti-loosening aim is fulfilled. The structure of the strong locking nut has the advantages of good anti-loosening effect and convenience for disassembling and assembling.
Description
Technical field
The present invention relates to a kind of structure technology of machinery standard spare, especially relate to a kind of structure with powerful locking function nut, specifically is a kind of structure of powerful locking nut.
Background technique
Nut is the connection and the fastening part commonly used of mechanical parts.After the nut warp of tightening used after a while, because the factor of mechanical vibration and others, nut tended to take place lax or comes off, in case this kind situation takes place, equipment can not normally be used, even serious security incident can take place.For this reason, at present in this important workplace or the Safety performance occasion of having relatively high expectations, all require nut to have locking function.
At present, make nut have the method that locking functions adopts and mainly contain the following aspects: one, between nut and part, add spring washer; Two, between nut and bolt, squeeze into fixing pin; Three, be locking way with two mutual diebacks of nut; Four, be that bolts and nuts are rivetted each other.
Though in the anti-loose method of above-mentioned nut, have different anti-loosing effects,, also there is scarce limit in various degree.Wherein, use and advantage of simple structure though adopt the method for spring washer to have,, there is the relatively poor scarce limit of anti-loosing effect.Between nut and bolt, squeeze into the good advantage of method tool anti-loosing effect of fixing pin, still, install cumbersomely, simultaneously, the dismounting of part is also cumbersome, and the easy damaged screw of tool; Adopt the locking method of two mutual diebacks of nut, though have the advantage of easy accessibility; There is the relatively poor shortcoming of locked effect equally; And the method that bolts and nuts are rivetted each other, though have the advantage of reliable lock; The locked method of this kind is disposable Placement, causes inconvenience for the replacing and the maintenance of part.
Summary of the invention
The objective of the invention is to: a kind of structure of powerful locking nut is provided, overcomes existing above-mentioned scarce limit in the existing nut pin locking structure.
The present invention realizes that the technological method that above-mentioned purpose adopts is: the structure of this a kind of powerful locking nut comprises locking nut, flange, counterbore, breach, pad, boss, stop pawl; It is characterized in that: described locking nut head is provided with flange; Flange end inwardly is provided with counterbore, and the limit oral area of counterbore is provided with the breach of some quantity in uniform way, and described locking pad is processed by spring steel material; Be provided with outstanding boss around the pad; The quantity of boss and consistent with the breach of the counterbore limit mouth of locking nut in the layout of circumferencial direction, and boss can be fastened in the breach of counterbore limit mouth just, and the centre of pad is provided with through hole; Around the through hole oral area, set out the stop pawl that some quantity are upturned in uniform way.
Beneficial effect: the present invention at first is placed on pad the counterbore inside of locking nut, and makes stop pawl be in the outside, simultaneously in use; Boss is fastened in the breach, and behind locking nut screwing, stop pawl is pressed towards fastening part, because the effect of elastic force; Making becomes one closely between locking nut, pad and the connected piece, thereby reaches locking purpose, so; It is good that the present invention has an anti-loosing effect, simultaneously, the advantage with easy accessibility arranged.
Description of drawings
Accompanying drawing 1 is a gasket construction stereogram of the present invention.
Accompanying drawing 2 is locking nut structural perspective of the present invention.
Shown in the figure: 1. locking nut, 2. flange, 3. counterbore, 4. breach, 5. pad, 6. boss, 7. stop pawl.
Embodiment
In the drawings; The structure of this a kind of powerful locking nut comprises locking nut 1, flange 2, counterbore 3, breach 4, pad 5, boss 6, stop pawl 7, and described locking nut 1 head is provided with flange 2, and flange 2 ends inwardly are provided with counterbore 3; The limit oral area of counterbore 3 is provided with the breach 4 of some quantity in uniform way; Check washer 5 is processed by spring steel material, is provided with outstanding boss 6, the quantity of boss 6 and consistent with the breach 4 of the counterbore 3 limit mouths of locking nut 1 in the layout of circumferencial direction around the pad 5; And boss 6 can be fastened in the breach 4 of counterbore 3 limit mouths just; The centre of pad 5 is provided with through hole, around the through hole oral area, sets out the stop pawl 7 that some quantity are upturned in uniform way.In use, at first pad 5 is placed on counterbore 3 inside of locking nut 1, and makes stop pawl 7 be in the outside; Simultaneously, boss 6 is fastened in the breach 4, after locking nut 1 is tightened; Stop pawl 7 is pressed towards fastening part; Because the effect of elastic force, making becomes one closely between locking nut 1, pad 5 and the connected piece, thereby reaches locking purpose.
