Abstract
The utility model discloses a blocking nut, which consists of a hard nut and a soft nut. One end surfaces of the hard nut and the soft nut are respectively provided with mutually meshed clipping teeth. When a machine part is fastened, the hard nut is tightened first, then the soft nut is tightened, and then the soft nut is revolved for an angle to make the thread thereof in misalignment with the thread of a bolt, and to make the clipping teeth on the end surfaces tightly mesh with the end surface of the hard nut, thereby achieving the anti-loosening aim. The structure of the blocking nut is reasonable, the anti-loosening performance is strong, the processing is convenient, and the application range is wide.
Description
The utility model relates to a kind of lock nut.
Existing nut major part is to utilize compression spring to control nut loosening, but still has the very big possibility that gets loose on the parts of vibration, in case nut loosening makes machine and vehicle cisco unity malfunction, parts damage, and danger is very big.For addressing this problem, existing at present a kind of cotter pin is used for controlling the loosening of nut, but its application supporting technology is difficult to setting, and is subjected to structural the influence, therefore can not be widely used on the most bolt, and application surface is narrow.
Patent of invention (ZL94116489.6) discloses a kind of sectional loosening-proof screw nut, this jam nut comprises the main nut that female thread is arranged in one and the secondary nut of first and second internal thread with different inner diameters, and main nut one end extends one and has externally threaded bump.Such jam nut complex structure, processing inconvenience.
The purpose of this utility model provides a kind of rational in infrastructure, easy to process, high safety, can be applicable to the lock nut of most of bolt.
For realizing this purpose, the technical solution of the utility model is: this lock nut is made up of a hard nut and a soft nut.One end face of described hard nut is provided with buckle teeth, and an end face of described soft nut is provided with the nut end face buckle teeth can intermeshing buckle teeth firmly.Identical with general nut, be respectively equipped with the screw thread that equates with bolt thread pitch in the screw of hard nut and soft nut.
Hard, soft two nuts that the utility model adopts end face to be provided with buckle teeth are formed, and are rational in infrastructure, easy to process.When fastening parts, earlier hard nut is screwed in bolt, after screwing, again soft nut is screwed, and then the rotation of soft nut is equal to or greater than 180 ° and less than 360 ° angle, make the screw thread dislocation of the screw thread and the bolt of soft nut, the end face buckle teeth tight engagement of the end face buckle teeth of soft nut and hard nut is connected as a single entity.Generally, if do not use spanner, soft nut can not become flexible, and therefore, can not become flexible between hard nut and the bolt yet.As seen, this lock nut is safe and reliable, can be widely used on the most bolt.
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Fig. 1 is the sectional drawing of a kind of mode of execution of the present utility model.
As shown in Figure 1, lock nut described in the utility model is made up of a hard nut (1) and a soft nut (2).One end face of described hard nut (1) is provided with concavo-convex alternate buckle teeth (3), and an end face of described soft nut (2) is provided with concavo-convex relative and can intermeshing buckle teeth (4) with hard nut (1) end face buckle teeth (3).Identical with general nut, be respectively equipped with screw thread (5) and the screw thread (6) that equates with bolt (7) screw thread (8) pitch in the screw of hard nut (1) and soft nut (2).When fastening parts (9), earlier hard nut (1) is screwed in bolt (7), during screw-in, be provided with the end face outside (non-direction of advance) of buckle teeth (3), after screwing, again soft nut (2) is screwed, during screw-in, be provided with the end face inside (direction of advance) of buckle teeth (4), and then soft nut (2) rotation is equal to or greater than 180 ° and less than 360 ° angle, make screw thread (8) dislocation of screw thread (6) with the bolt (7) of soft nut (2), end face buckle teeth (3) tight engagement of the end face buckle teeth (4) of soft nut (2) and hard nut (1) is connected as a single entity.Lock nut is fixed on the bolt (7), can not become flexible.If when carrying out parts repairing or replacing, should unscrew soft nut (2) with spanner outside (non-direction of advance) earlier, unscrew hard nut (1) again.
Claims (3)
1. a lock nut is characterized in that being made up of a hard nut (1) and a soft nut (2).
2. lock nut as claimed in claim 1 is characterized in that an end face of hard nut (1) is provided with buckle teeth (3), and an end face of soft nut (2) is provided with nut (1) end face buckle teeth (3) can intermeshing buckle teeth (4) firmly.
3. lock nut as claimed in claim 1, it is characterized in that when fastening parts (9), earlier hard nut (1) is screwed in bolt (7), after screwing, again soft nut (2) is screwed, and then soft nut (2) is rotated to an angle, make screw thread (8) dislocation of screw thread (6) with the bolt (7) of soft nut (2), end face buckle teeth (3) tight engagement of the end face buckle teeth (4) of soft nut (2) and hard nut (1) is connected as a single entity.
