Abstract
The utility model discloses a loosening-preventing nut component, which belongs to the technical field of fasteners and comprises a nut and a gasket which are coaxially arranged, wherein the nut and the gasket are movably connected through an interlocking retaining structure, the interlocking retaining structure comprises a retaining block A positioned at the bottom of the nut and a retaining block B positioned at the top of the gasket, the retaining block A and the retaining block B can be completely wedged, and the vertical distance between the top of the nut and the bottom of the gasket is shortest when the retaining block A and the retaining block B are completely wedged; when the nut and the gasket rotate relatively, the stopping block A and the stopping block B slide relatively to increase the vertical distance between the top of the nut and the bottom of the gasket gradually, the bottom of the gasket is provided with anti-slip teeth, and the wedging surface of the stopping block A and the stopping block B is an arc-shaped curved surface. The nut and the gasket adopt the arc-shaped wedging surfaces, so that the contact area is increased, the pressure of the wedging surfaces is reduced, the abrasion-resistant time is longer, and the anti-loosening service life of the nut assembly is prolonged.
Description
Technical Field
The utility model relates to the technical field of fasteners, in particular to an anti-loosening nut component.
Background
Nuts are common fastener fittings, often used with bolts. Under high frequency, large amplitude vibration or impact conditions, the nut typically moves relative to the bolt, resulting in loose displacement of the fastened object, i.e., failure of the fastening. For this reason, the search for anti-loosening fasteners has been ongoing.
The better mode of locking effect at present just sets up the interlocking structure of nut, nut. For example, in the integrally movably connected nut and washer assembly structure disclosed in the chinese application CN202011057385, wedge-shaped blocks engaged with each other are arranged on the contact surfaces of the nut and the washer, so that the wedge-shaped blocks are staggered to press the washer when the nut is loosened, and the nut and the washer are still kept in a fastened state. It is known that under vibration and impact conditions, a certain relative displacement exists between the nut and the gasket, so that friction is continuously generated, once the nut is worn and displaced to cross the wedge block, the anti-loosening failure is caused, and at present, people try to improve the anti-loosening failure so as to prolong the anti-loosening service life.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model provides the anti-loosening nut assembly, the wedging surface between the nut and the gasket is arc-shaped, the contact area is increased, the pressure of the wedging surface is reduced, the abrasion is reduced, and the abrasion-resistant time is longer. The specific scheme of the utility model is as follows:
a locking nut component comprises a nut and a gasket which are coaxially arranged, wherein the nut and the gasket are movably connected through an interlocking retaining structure, the interlocking retaining structure comprises a retaining block A positioned at the bottom of the nut and a retaining block B positioned at the top of the gasket, the retaining block A and the retaining block B can be completely wedged, and the vertical distance between the top of the nut and the bottom of the gasket is shortest when the retaining block A and the retaining block B are completely wedged; when the nut and the gasket rotate relatively, the stopping block A and the stopping block B slide relatively to increase the vertical distance between the top of the nut and the bottom of the gasket gradually, the bottom of the gasket is provided with anti-slip teeth, and the wedging surface of the stopping block A and the stopping block B is an arc-shaped curved surface.
In an embodiment of the present invention, the retaining block a is a convex arc-shaped curved surface, and the thrust block B is a concave arc-shaped curved surface.
As an embodiment of the present invention, the nut is a hexagonal nut; the number of the anti-slip teeth is 12, and the anti-slip teeth are arranged at the bottom of the gasket in an annular array.
Compared with the prior art, the method has the following advantages:
the nut and the gasket adopt the arc-shaped wedging surfaces, so that the contact area is increased, the pressure of the wedging surfaces is reduced, the abrasion-resistant time is longer, and the anti-loosening service life of the nut assembly is prolonged.

Example 1:
referring to fig. 1 and 2, a loosening prevention nut assembly includes a nut 1 and a washer 2 coaxially disposed, the nut 1 is a hexagonal nut, the nut 1 and the washer 2 are movably connected by an interlocking retaining structure, the interlocking retaining structure includes a retaining block a 101 located at the bottom of the nut 1 and a retaining block B201 located at the top of the washer 2, the retaining block a 101 and the retaining block B201 can be completely wedged, and when the two are completely wedged, the vertical distance between the top of the nut 1 and the bottom of the washer 2 is shortest; when the nut 1 and the gasket 2 rotate relatively, the stopping block A101 and the stopping block B201 slide relatively to increase the vertical distance between the top of the nut 1 and the bottom of the gasket 2, the bottom of the gasket 2 is provided with the anti-slip teeth 202, the wedging surface of the stopping block A101 and the stopping block B201 is an arc-shaped curved surface, the stopping block A101 is a convex arc-shaped curved surface, and the thrust block B201 is a concave arc-shaped curved surface.
Specifically, the nut is a hexagonal nut; the number of the anti-slip teeth is 12, and the anti-slip teeth are arranged at the bottom of the gasket in an annular array.
When the nut component is disassembled, the spanner simultaneously clamps the retaining block A101 and the retaining block B201 to rotate together.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
