Abstract
The invention discloses a locking nut connection structure comprising a connector and a screw penetrating the connector. A nut is tightened on the screw to fasten the connector. The connector is provided with a counter groove corresponding to the nut. After the nut is tightened, the bottom of the nut is placed in the counter groove. The bottom of the nut is provided with a circular skirt. The diameter of the skirt is larger than that of the counter groove. After the nut is tightened, large friction occurs between the skirt which curls and the counter groove, and the nut and the screw can less easily rotate relative to each other. Therefore, loosening of the nut which is fastened can be prevented; the locking nut connection structure is simple in structure and good in locking performance.
Description
Technical field
The present invention relates to fastening piece linkage structure, relate in particular to a kind of Anti-loosening nut linkage structure.
Background technique
During the work of common mechanical machine, have generation of vibration, this not only consumes a part of power, waste energy, vibration simultaneously also can cause that each connected element produces loosening phenomenon, especially the position connecting at nut bolt, once occur that nut loosening just has the possibility coming off, causes accident to produce.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of Anti-loosening nut linkage structure, simple in structure, and anti-loosening performance is good.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: Anti-loosening nut linkage structure, comprise link and through the screw rod of link, on screw rod, screw nut link is fastening, on described link, corresponding described nut arranges a deep gouge, nut screws rear bottom and is located in deep gouge, and described nut bottom is provided with a circle annular shirt rim, and the diameter of described shirt rim is greater than deep gouge diameter.
As preferably, outer ring, described shirt rim is provided with sawtooth.
As preferably, described deep gouge top is circular, and described deep gouge bottom is regular polygon.
As preferably, the height of described shirt rim is less than the height of deep gouge.
As preferably, described dop is triangle, trapezoidal or square.
The present invention is provided with a circle annular shirt rim in nut bottom, the diameter of shirt rim is greater than deep gouge diameter on link, like this, after nut screws, shirt rim crispatura and deep gouge between produce larger frictional force, between nut and screw rod, be just not easy relative rotation, thereby can prevent loosening after fastening nuts, simple in structure, anti-loosening performance is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan view of the present invention.
Embodiment
As depicted in figs. 1 and 2, embodiment for a kind of Anti-loosening nut linkage structure of the present invention, comprise link 2 and through the screw rod 21 of link, on screw rod, screw nut 1 link is fastening, on described link, corresponding described nut arranges a deep gouge 20, nut screws rear bottom and is located in deep gouge, and described nut bottom is provided with a circle annular shirt rim 10, and the diameter of described shirt rim is greater than deep gouge diameter.Outer ring, described shirt rim is provided with sawtooth 11.Described deep gouge top is circular, and described deep gouge bottom is regular polygon.The height of described shirt rim is less than the height of deep gouge.
The nut 1 of screwing on, nut screws rear bottom and is located in deep gouge 20, nut screws in process, the sawtooth 11 that the annular shirt rim 10 that nut bottom is provided with and outer ring, shirt rim arrange crispatura and deep gouge sidewall between produce larger frictional force, wherein, wherein deep gouge bottom is that regular polygon can further improve the snap-in force between nut and deep gouge, loosening to prevent after fastening nuts.
