Abstract
An anti-loose nut is formed by additionally arranging a retaining side (2) on any one end surface of a nut (1); the retaining side and the nut form an integral structure, both an inner ring slot and a through hole are formed on the retaining side, the diameter of the through hole is larger than the nominal diameter of the inner threaded hole of the nut, the diameter of the inner ring slot is larger than the diameter of the through hole, an anti-loose ring (3) is arranged inside the inner ring slot, the external diameter and the width of the anti-loose ring are respectively matched with the diameter and the width of the inner ring slot, and the inside diameter of the anti-loose ring is smaller than the nominal diameter of the inner threaded hole of the nut. The anti-loose nut provided by the utility model has a simple structure, is easy to process, does not require a spring gasket or an anti-loose gasket to be configured, is very fast and convenient in fastening, and can effectively prevent the nut from the self releasing phenomenon caused by looseness.
Description
Technical field
The utility model belongs to technical field of fastening, especially a kind of Anti-loosening nut.
Background technique
General nut itself does not possess locking effect, produces loosening or obscission for preventing nut, is everlasting and installs spring washer or check washer additional between nut and pretension parts, or use simultaneously two nuts.
If itself has anti-loose structure nut, can bring revolutionary change to fastening piece.
Summary of the invention
In order to overcome defects, the utility model has designed a kind of Anti-loosening nut, and this Anti-loosening nut is simple in structure, and easy processing can prevent effectively that nut is because of the loosening self falling phenomenon that produces.
In order to realize the purpose of foregoing invention, the utility model adopts following technological scheme:
A kind of Anti-loosening nut, to set up a circle rib at arbitrary end face of nut, rib and nut are integrally formed structure, rib is respectively arranged with inner groove and through hole, the diameter of described through hole is greater than the nominal diameter of nut inner threaded hole, and the diameter of described inner groove is greater than the diameter of described through hole, and DNA releaxed circular DNA is prevented in configuration in described inner groove, the external diameter of anti-DNA releaxed circular DNA and width are complementary with diameter and the width of described inner groove respectively, and the internal diameter of anti-DNA releaxed circular DNA is less than the nominal diameter of nut inner threaded hole.
Anti-DNA releaxed circular DNA is made by nonmetallic material.
Owing to adopting technological scheme as mentioned above, the utility model produces following advantage:
1, Anti-loosening nut of the present utility model is simple in structure, and easy processing need not configure spring washer or check washer in addition, tightens up very fast and convenient, can prevent effectively that nut is because of the loosening self falling phenomenon that produces.
2, Anti-loosening nut of the present utility model can play two unexpected results, and the one, anti-DNA releaxed circular DNA can play the effect of auxiliary locking, and the 2nd, anti-DNA releaxed circular DNA can absorb or alleviate vibrations, thereby improves the fastening effect of Anti-loosening nut.
Description of drawings
Fig. 1 is the structural representation sketch that partly cuts open of the present utility model.
In Fig. 1: the 1-nut; The 2-rib; 3-prevents DNA releaxed circular DNA.
Embodiment
The utility model is a kind of Anti-loosening nut.
Anti-loosening nut of the present utility model is to set up a circle rib 2 at arbitrary end face of standard nut or non-standard nut, rib 2 is integrally formed structure with nut 1, rib 2 is respectively arranged with inner groove and through hole, the diameter of described through hole is greater than the nominal diameter of nut 1 interior threaded hole, the diameter of described inner groove is greater than the diameter of described through hole, the anti-DNA releaxed circular DNA 3 of configuration in described inner groove, the external diameter of anti-DNA releaxed circular DNA 3 and width are complementary with diameter and the width of described inner groove respectively, and the internal diameter of anti-DNA releaxed circular DNA 3 is less than the nominal diameter of nut inner threaded hole.
Anti-DNA releaxed circular DNA 3 is made by nonmetallic material, and anti-DNA releaxed circular DNA 3 preferably has certain pliability and damping and amortization, and damping constant is the bigger the better.
When Anti-loosening nut was fastened on the bolt of pretension parts, due to the diameter of the described bolt internal diameter greater than anti-DNA releaxed circular DNA, anti-DNA releaxed circular DNA was compressed in the described inner groove of rib and is wrapped in around described bolt and plays the fastening effect of auxiliary locking.
When Anti-loosening nut ran into vibrations, friction, collision, anti-DNA releaxed circular DNA can absorb or alleviate vibrations this moment, improved the fastening effect of Anti-loosening nut.
Claims (2)
1. Anti-loosening nut, it is characterized in that: set up a circle rib (2) at arbitrary end face of nut (1), rib (2) is integrally formed structure with nut (1), rib (2) is respectively arranged with inner groove and through hole, the diameter of described through hole is greater than the nominal diameter of nut (1) interior threaded hole, the diameter of described inner groove is greater than the diameter of described through hole, the anti-DNA releaxed circular DNA (3) of configuration in described inner groove, the external diameter of anti-DNA releaxed circular DNA (3) and width are complementary with diameter and the width of described inner groove respectively, the internal diameter of anti-DNA releaxed circular DNA (3) is less than the nominal diameter of nut (1) interior threaded hole.
2. Anti-loosening nut according to claim 1, it is characterized in that: anti-DNA releaxed circular DNA (3) is made by nonmetallic material.
