Abstract
A nut locking mechanism comprises a common nut 3, an upper part 1 and a lower part 2. The upper part 1 is a convex nut provided with a cylindrical protrusion 4 around a threaded hole of the convex nut; the lower part 2 is a nut cap provided with a through hole 5. The nut locking mechanism according to the technical scheme has the advantage that nut locking effect is improved at the premise of not affecting bearing capacity of the nuts.
Description
Technical field:
The present invention relates to a kind of connection fastening piece, particularly a kind of nut check mechanism.
Background technique:
Existing nut anti-looseness technology is varied, has plenty of use check washer, the schemes such as double nut, has plenty of and improves the inherence of plain nut and formal structure, and what have is then that to adopt abnormity nut combination to carry out coupling locking.Wherein, the anti-loosing effect of first kind scheme is very limited, and rear two class schemes likely cause nut unbalance stress, and bearing capacity such as to weaken at the problem.
Summary of the invention:
In order to improve the limitation of above-mentioned prior art, the invention provides a kind of nut check mechanism.
Technological scheme of the present invention is: a kind of nut check mechanism, it comprises a plain nut, mechanism top and mechanism bottom, described mechanism top is a knurled nut being provided with column projection thereon around its tapped hole, it is characterized in that: mechanism bottom is a nut cap, it there is a through hole, described projection matches with described through hole, one of outer rim center line of through hole center line on nut cap and the projection on knurled nut is coaxial with the tapped hole center line of knurled nut, and the shape of nut cap bottom can be overlapped and is buckled on plain nut.One of described projection and described through hole are taper, and described projection and described through hole both can also be all taper, and described through hole can also be that taper connects columniform hole.Between described nut cap and plain nut, nonmetallic gasket is set.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of nut check mechanism of the present invention.
Wherein, 1, mechanism top, 2, mechanism bottom, 3, plain nut, 4, mechanism's top projection, 5, the through hole of mechanism bottom.
Schematic diagram when Fig. 2 is the locking of a kind of nut check mechanism of the present invention.
Specific embodiment:
Composition graphs 1, Fig. 2, a kind of nut check mechanism, it comprises a plain nut 3, mechanism top 1 and mechanism bottom 2, described mechanism top 1 is a knurled nut being provided with column projection 4 thereon around its tapped hole, mechanism bottom 2 is nut caps, it there is a through hole 5, described projection 4 matches with described through hole 5, one of described through hole 5 center line and the outer rim center line of described projection 4 are coaxial with the tapped hole center line of knurled nut, and the shape of nut cap bottom can be overlapped and is buckled on plain nut 3.One of both described projection 4 and described through hole 5 are taper, can also both be all taper, described through hole 5 can also be that taper connects columniform hole.Between described nut cap and plain nut 3, can also nonmetallic gasket be set.
During use, first tightened by screw rod by plain nut 3, then cover nonmetallic gasket, nut cap on plain nut 3 by screw rod, then projection 4 is screwed in the through hole 5 of nut cap by screw rod by knurled nut, locks.
Claims (5)
1. a nut check mechanism, it comprises a plain nut, mechanism top and mechanism bottom, described mechanism top is a knurled nut being provided with column projection thereon around its tapped hole, it is characterized in that: mechanism bottom is a nut cap, it there is a through hole, described projection matches with described through hole, one of outer rim center line of through hole center line on nut cap and the projection on knurled nut is coaxial with the tapped hole center line of knurled nut, and the shape of nut cap bottom can be overlapped and is buckled on plain nut.
2. a kind of nut check mechanism according to claim 1, is characterized in that: one of described projection and described through hole are taper.
