Abstract
The utility model discloses a built-in self-locking nut, and belongs to the technical field of nuts. The inner side surface of the nut is provided with a step-shaped self-locking clamping groove consisting of an annular deep clamping groove and a shallow clamping groove; wherein, the metal spring sheet is embedded in the deep clamping groove, and the rubber ring is embedded in the shallow clamping groove; the ring width of the metal elastic sheet is higher than the inner side surface of the nut, and the top of the metal elastic sheet is inclined to one side of the rubber ring. According to the utility model, through the extrusion action of the built-in metal spring plate and the rubber ring, the installation effect of the nut is greatly improved, and the installation effect of anti-skid and vibration prevention is achieved.
Description
Technical Field
The utility model relates to a nut, in particular to a built-in self-locking nut with good installation effect, looseness resistance and vibration resistance.
Background
Nuts are parts that are screwed with bolts or screws to perform a tightening function. When the nut is used in a complex environment, the common nut is easy to loosen gradually due to other reasons such as long-time vibration in the use process, and the use effect cannot be achieved.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide the built-in self-locking nut which has good installation effect, and is loose-proof and vibration-proof.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
The inner side surface of the nut is provided with a step-shaped self-locking clamping groove consisting of an annular deep clamping groove and a shallow clamping groove; wherein, the metal spring sheet is embedded in the deep clamping groove, and the rubber ring is embedded in the shallow clamping groove; the ring width of the rubber ring is higher than the inner side surface of the nut, and the ring width of the metal elastic sheet is higher than the inner side surface of the rubber ring and inclines to one side of the rubber ring at the top.
Preferably: the section of the rubber ring is trapezoid with narrow inside and wide outside.
Preferably: and a part of the metal elastic sheet, which is higher than the inner side surface of the nut, is provided with a plurality of protruding points on at least the outer side surface.
Preferably: the inclined width of the metal spring plate is not larger than the groove width of the shallow clamping groove.
Preferably: the self-locking clamping groove is positioned in the middle of the nut.
When the nut is used, the bolt or the screw enters from one side of the metal elastic piece of the nut, the metal elastic piece higher than the inner side surface of the nut is pressed to the surface of the rubber ring, and the trapezoid section of the rubber ring enables the two sides of the rubber ring to leave an installation space, so that the nut is facilitated to be installed; after the installation is completed, the rubber ring provides elastic force for the metal elastic sheet, meanwhile, the metal elastic sheet provides friction force for the bolt or the screw rod so as to form pretightening force, the nut is prevented from sliding, and the installation effect is greatly improved. The convex points on the surface of the metal elastic sheet fall into the thread pitch, so that the anti-loosening installation effect is further improved.

Fig. 2 is an enlarged structural view at a.
In the figure: 1. a metal spring plate; 2. a rubber ring.
Detailed Description
The structure and principles of the present utility model are fully described in connection with specific embodiments so as to enable those skilled in the art to understand and practice them.
As shown in fig. 1 and 2, the inner side surface of the nut is provided with a step-shaped self-locking clamping groove consisting of an annular deep clamping groove and an annular shallow clamping groove; wherein, the metal spring plate 1 is embedded in the deep clamping groove, and the rubber ring 2 is embedded in the shallow clamping groove; the ring width D of the rubber ring 2 is higher than the inner side surface M of the nut, and the ring width D of the metal elastic sheet 1 is higher than the inner side surface N of the rubber ring 2 and inclines to one side of the rubber ring 2 at the top.
When the nut is installed, the nut enters from one side of the metal elastic sheet 1, and the metal elastic sheet 1 is pressed on the surface of the rubber ring 2 by extrusion, so that the anti-skid and vibration-proof effects are achieved after the installation is completed.
Preferably: the section of the rubber ring 2 is trapezoid with narrow inside and wide outside. The trapezoid structure makes the rubber ring 2 leave a certain space on two sides of the shallow clamping groove, and reserves a space for the pressed deformation of the rubber ring 2 in the installation process, so that the installation is faster.
Preferably: at least the outer side surface of the metal spring plate 1, which is higher than the inner side surface of the nut, is provided with a plurality of protruding points. The design of the convex points further improves the pre-tightening installation effect, and the convex points falling into the screw pitch can greatly improve the anti-skid and vibration-proof effects.
Preferably: the inclined width G of the metal spring plate 1 is not larger than the groove width G of the shallow clamping groove.
Preferably: the self-locking clamping groove is positioned in the middle of the nut.
The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model or modifications to equivalent embodiments using the above disclosed method without departing from the technical principle and scope of the solution of the present utility model. Therefore, any combination, modification or substitution of the technical features disclosed in the present utility model according to the technical substance of the present utility model should be within the protection scope of the technical solution of the present utility model, wherever the principle or the solution of the present utility model is not deviated.
