Abstract
A self-locking nut assembly comprises at least an upper nut and a lower nut which are combined to form a component. The self-locking nut assembly is characterized in that the upper nut is a split nut with a slot opened on the lateral surface of the upper nut, and an external cone station is arranged on the contacting part of the upper nut and the lower nut and is in the shape of a whole ring with a notch; the inner surface of the cone station can be provided with thread. An internal cone-shaped table is arranged at the contacting part of the lower nut, and the upper nut and is matched with the external cone-shaped table of the upper nut. The working method is as follows: firstly, screwing the lower nut on the screw; screwing the upper nut in the screw after tightening the lower nut until the external cone-shaped table of the upper nut adheres to the internal cone-shaped table of the lower nut; continuing to tighten the upper nut; the whole upper nut with a whole notch contracting under the action of the internal cone-shaped table of the lower nut, thus integrally clasping the screw.
Description
Technical field
The invention belongs to a kind of attachment means structure, especially a kind of structure of modular nut is mainly used in being locked mutually of various nuts.
Background technique
Nut is a kind of fastening piece commonly used, and common and screw combinations forms a cover securing means.In order effectively to reach more efficiently fastening effect, prevent that the phenomenon that gets loose voluntarily from appearring in single nut, adopt two nuts mutually and lump together use in many places, in the hope of further increasing fastening effect.
The nut that is adopted now and closing commonly directly is screwed in two nuts together exactly, but its effect still is not very good like this, and bigger in many vibrations, the operating mode place that frequency is higher still the phenomenon that nut gets loose can occur.(number of patent application is 200410097308.9 to Chinese patent literature, denomination of invention is " locking nut ") a kind of novel self-locking nut assembly disclosed, this locking nut comprises an internal thread (5) that is designed to be screwed on the screw thread of axle, and comprise at least one locking element (8), by at least one lock screw (9), described locking element can be pressed on the screw thread of axle with its lock portion (8a), locking nut prevents unexpected loosening thus, therefore, locking element (8) all is provided with a releasing device, described releasing device comprises at least one screw (10), described screw is arranged to and can carries out threaded joint with locking element (8), so that locking element (8) is subjected to a radial pull, thereby make locking element (8) unclamp lock screw (9) back and axle disengaging threaded joint.But this nut structure complexity is made difficult the realization, thereby is difficult to generally promote.
(number of patent application is 200480024154.9 to Chinese patent literature, denomination of invention is " locking nut ") another kind of novel self-locking nut assembly disclosed, locking nut refer to is in order to prevent to be fastened on the fastening loosening locking nut (1) with nut (7) on the bolt (6), is included in the inner nut main body (2) that forms tapped hole (4) and form groove (30) on the periphery of the tapped hole (4) of a side seat surface (3) and is formed on groove (30) and goes up and a plurality of projections (5) identical with nut main body (2) material.Projection (5) has the inner side surface (32) of tapped hole (4) side that forms towards central direction and outer side surface tapped hole (4) opposition side of nut main body (2) with in the mode of the prolongation of the internal surface of the tapped hole (4) that becomes nut main body (2) from the boundary portion of the seat surface (3) of nut main body (2) and groove (30).The degree of depth of groove (30) is set at following size: be fastened on bolt (6) when going up at locking nut (1), projection (5) even be crushed can not enter between the fastening seat surface (8) and the seat surface (3) of nut main body (2) with nut (7) yet.But the thinking of this assembled nut still be confined to the part by on lower nut effect each other make the part screw thread be in clamped condition.Formed clamping area is very limited, and still being difficult to satisfy the demand more, high strength clamps the needs that require.Especially upper cap nut in this self-locking nut assembly clamps the position, must be made into threaded arc piece claw-like structural type, and the difficulty of processing of its nut itself is bigger, so necessary this is improved.
Summary of the invention
The objective of the invention is to: at the deficiency of existing self-locking nut assembly, it is bigger that exploitation one cover clamps area, better effects if, and the self-locking nut assembly of easy processing and fabricating.
The objective of the invention is to be achieved through the following technical solutions: a kind of self-locking nut assembly, comprise a upper cap nut at least, a lower nut is combined to form assembly by upper cap nut and lower nut.Be characterized in that described upper cap nut is the opening nut, have groove in the nut side, and be provided with the external conical shape platform of being with opening in upper cap nut and lower nut contact position, the external conical shape platform is the whole round of trough of belt mouth, and taper platform inner face can be threaded or not threaded.Be provided with the inner conical platform that matches with upper cap nut external conical shape platform at the position that lower nut contacts with upper cap nut.
Method of work of the present invention is: earlier lower nut is screwed on the screw rod, again upper cap nut is twisted as screw rod after tightening, fit together until external conical shape platform in the upper cap nut and the inner conical platform on the lower nut, continue to tighten upper cap nut again, the external conical shape platform of upper cap nut will be under the effect of lower nut inner conical platform, because upper cap nut has whole notch, upper cap nut will be under the effect of lower nut inner conical platform overall shrinkage, thereby integral body is held screw rod tightly.
The invention has the advantages that: because upper cap nut is a whole side fluting, will be overall shrinkage when shrinking therefore, so the threaded area that clamps will increase greatly, the screw thread frictional force that is produced will be bigger also, so it is fine to clamp effect.On the other hand.Owing to be by the whole fluting of upper cap nut, locking mainly is the screw-threaded coupling by nut self, so needn't need taper platform position that screw thread is set, and the external conical shape platform of upper cap nut directly can be made whole loop-shaped, processing will be much easier than the arc bulk like this, can save manufacture cost greatly.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the structural representation plan view of the embodiment of the invention;
Fig. 3 is the structural representation of another embodiment of the present invention.
