Abstract
The invention discloses a combined eccentric anti-loosening nut. The combined eccentric anti-loosening nut comprises a main nut and an auxiliary nut. One end of the main nut is provided with a conical boss. One end of the auxiliary nut is provided with a conical depressed platform. The conical boss of the main nut and the conical depressed platform of the auxiliary nut are arranged in a matching mode. The anti-loosening function of the main nut and the auxiliary nut is fulfilled in the manner that threads are extruded by conicity in a radial direction so that superior anti-vibration performance is obtained. The combined eccentric anti-loosening nut can be repeatedly used and exert a same loosening effect. Free from a spring gasket, the combined eccentric anti-loosening nut has purposes of fastening while loosening. The combined eccentric anti-loosening nut has a simple structure, is easy to machine and convenient to install.
Description
Technical field
The present invention relates to a kind of combination type bias stop nut.
Technical background
It is vibrated, load change big, impulse ratio is relatively big, at these to there is the position that uses nut to connect on many equipment
Position is often due to by shock and vibration, plain nut adds regular the loosening of locking form of spring washer, causes parts to take off
Falling, loosen, serious meeting causes equipment damage to work, and needs irregular inspection, improves the use cost of equipment,
Especially some be not easily seen or the position that is not easy fastening, this phenomenon is more serious, and the equipment that can directly contribute damages
Ruin, even human safety issues.
Summary of the invention
For the problems referred to above, the present invention provides a kind of combination type bias stop nut, can reach to fasten and can loosen effect
The best purpose, and simple in construction, handling ease, easy for installation.Two nuts are used to play interlocking while fastening real
Existing locking functions, improves reliability, reduces simultaneously and check number of times, improve the service life of parts connecting portion.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of combination type bias stop nut, it is characterised in that: include mother nut and secondary nut；One end of mother nut has a circle
Cone boss；One end of secondary nut has a conical concave stage；The conical boss of mother nut is equipped with the conical concave stage of secondary nut.
Further, mother nut is concentric with secondary nut place thread center axis.
Further, the conical concave stage central axis of secondary nut is the most concentric with the screw thread place central axis of secondary nut.
Further, the conical boss central axis of mother nut is the most concentric with the screw thread place central axis of mother nut.
Further, the conical boss on mother nut is identical with the tapering of the conical concave stage on secondary nut.
Further, the conical boss on mother nut is different from the degree of depth of the conical concave stage on secondary nut.
Further, the conical boss height on mother nut is less than the degree of depth of the conical concave stage on secondary nut.
The invention has the beneficial effects as follows:
1, mother nut is realized by tapering radial compression screw thread with secondary nut anti-looseness function, has superior resistance to shock.
2, this combination type bias stop nut can be reused, and plays same relaxation effect.
3, this combination type bias stop nut can save spring washer.

Detailed description of the invention
As shown in figs 1 to 6, this Combined locknut includes mother nut 1 and secondary nut 2.Mother nut 1 wherein one
End is the outwardly conical boss conical surface 3, and the other end is substantially planar.Secondary nut 2 wherein one end is the circle being inwardly recessed
The cone concave station conical surface 4, the other end is substantially planar.The tapering phase of the conical boss on mother nut and the conical concave stage on secondary nut
With, the degree of depth is different.The conical concave stage central axis of secondary nut is the most concentric with the screw thread place central axis of secondary nut.
When needs carry out fastening locking, it is screwed to mother nut 1 on connecting bolt 5 to be connected by securing member, and according to
Regulation requires to tighten mother nut 1 on request, and the conical boss conical surface 3 is towards outward, and such mother nut 1 plays interconnection function, so
After pair nut 2 is screwed on connecting bolt 5, the conical concave stage conical surface 4 is towards the conical boss conical surface 3 of mother nut 1, and revolves
Enter secondary nut 2, until the conical concave stage conical surface 4 on secondary nut 2 contacts with the conical boss conical surface 3 on mother nut 1, continue rotation
Enter secondary nut 2, owing to secondary nut 2 thread center axis is the most concentric with the secondary nut 2 conical concave stage conical surface 4 central axis, so exist
While secondary nut 2 precession, the mother nut 1 conical boss conical surface 3 produces extruding with the secondary nut 2 conical concave stage conical surface 4, due to
Extruding can make mother nut 1 and connecting bolt 5, produce and thread center between secondary nut 2 and the connection screw thread of connecting bolt 5
The radial force that axis is vertical, this radial force interacted just for mother nut 1, secondary between nut 2, connecting bolt 5 mutual
Acting on coupling mechanism force together, this coupling mechanism force serves good locking effect, and secondary nut 2 precession connecting bolt 5
Distance the longest, it is the biggest that the mother nut 1 conical boss conical surface 3 and the secondary nut 2 conical concave stage conical surface 4 produce extruding force, coupling mechanism force
The biggest, anti-loosing effect can be more preferably.
Installation process: first mother nut 1 is screwed in connecting bolt 5 to precalculated position, and on request mother nut 1 is tightened, so
After pair nut 2 is being screwed in connecting bolt 5, until the conical boss conical surface 3 of two nuts, the male and fomale(M&F) of the conical concave stage conical surface 4
In conjunction with, play three's interlocked with thus reach to loosen effect, be further continued for screwing in secondary nut 2 and reach regulation and require whole process knot
Bundle, reaches lockup state and plays locking effect.
