Abstract
The utility model discloses a nut with a self locking property, which includes a nut (1). One side of a screw hole (2) of the nut (1) is round and another side is oval, the screw hole (2) of the nut (1) gradually changes from being round to oval. The utility model makes the screw hole of the nut be out of shape by extruding one side of a normal nut on the basis of the normal nut, when the asquish nut screws down a screw rod and enters the deformed screw hole section of the nut, a self locking force which is produced by the elastic deformation of the screw hole closely connects the nut with the screw rod for forming the self locking. After the process, the utility model provides the nut with a connection property and a self locking property and increases the reliability of the nut.
Description
Technical field
The utility model relates to a kind of nut, particularly relates to a kind of nut with self-locking property.
Background technique
Since mechanical industry was come out, nut had just produced, and nut is with a long history, has become the fastening of a kind of extensive utilization
Part is as being extensive use of invariably on the instruments such as railway, bridge, electric power, mine, aircraft, tank, automobile.But plain nut in use, and particularly under alternation vibrations and high-frequency vibration, the fastening effect of nut can weaken, thereby loose voluntarily
Take off, easily have an accident.Institute thinks and prevents that nut from getting loose, reduce potential safety hazard, method at present commonly used is, the double nut back of the body is tight, increase spring washer or on nut method such as bayonet lock solve, these methods have not only increased the consumption of material, time-consuming, and complex structure, use are not too convenient, and of long duration still can get loose, fastening effect is also unreliable, has potential safety hazard.
Summary of the invention
The purpose of this utility model is: provide a kind of nut of simple in structure, safe and convenient to use, band self-locking property that self-locking property is good, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises nut (1), and screw (2) one ends of nut (1) are oval for the circle the other end, and the screw (2) of nut (1) fades to ellipse by circle.
Compared with the prior art, the utility model is by pushing the one end on the basis of plain nut, make the screw of nut produce distortion, when the nut that will flatten is screwed into screw rod, the self-locking pressure that resiliently deformable produced because of screw when screw rod enters into the distortion screw section of this nut closely links together nut with screw rod, form self-locking, make nut have the switching performance of making and self-locking property simultaneously through such processing, improve the reliability of nut, the utility model is simple in structure, easy to implement simultaneously, safety reliable for effect, can be popularized and applied to various mechanical industries, good economic benefits and social benefit are arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Embodiment
Embodiment of the present utility model: as illustrated in fig. 1 and 2, technology is made nut 1 routinely earlier, the method of employing extruding is pushed an end of nut 1 then, make the screw 2 of this end nut 1 produce distortion, the screw 2 of nut 1 becomes an end and is ellipse for the circle the other end, and the screw 2 of nut 1 be fade to by circle oval-shaped, in use, screw rod screws in from the end that nut 1 does not have distortion, when entering into the distortion screw section of nut 1, nut 1 will be all the more tight with contacting of screw rod, make oval-shaped screw 2 produce resiliently deformable, make nut apply radial pressure, thereby will certainly increase the frictional force between screw rod and nut thread screw rod, form self-locking, make nut 1 have switching performance and self-locking property simultaneously.
Claims (1)
1. nut with self-locking property, it comprises nut (1), is characterised in that: screw (2) one ends of nut (1) for the circle the other end for oval, and the screw (2) of nut (1) fades to ellipse by circle.
