Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically to a spherical anti-loosening nut using an arc-shaped washer. Background Technology

[0002] Traditional nuts and bolts use washers to prevent loosening during use. However, in practice, horizontal annular washers are prone to loosening, causing the nut to shift and preventing proper tightening. Therefore, our company has innovated to address this problem. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a spherical anti-loosening nut with an arc-shaped washer.

[0004] The present invention discloses a spherical anti-loosening nut using an arc-shaped washer, comprising a spherical anti-loosening nut body 1, which includes a nut cylinder with open ends, an internal thread inside the nut cylinder, a regular hexagonal facet on the outer side of the nut cylinder, an arc-shaped annular facet at the front end of the regular hexagonal facet, a convex cylinder at the front end of the nut cylinder, and an arc-shaped washer movably fitted onto the convex cylinder to form a spherical anti-loosening nut.

[0005] Furthermore, the front end face of the convex cylinder is an inwardly inclined frustum shape, which matches the front arc surface of the arc-shaped gasket.

[0006] Furthermore, the center of the nut cylinder, the hexagonal facet, and the convex cylinder are all on the same straight line and are integrally formed.

[0007] Furthermore, the arc-shaped gasket is made of 65Mn / 60si2MnA spring steel.

[0008] Furthermore, the arc-shaped washer includes a washer with a central hole at its center. The diameter of the central hole is larger than the diameter of the cross-sectional circle of the nut cylinder. The top and bottom of the washer 21 are arc-shaped surfaces with an angle of 5°-30°.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows: The spherical anti-loosening nut with an arc-shaped washer described in this utility model uses a nut with an arc-shaped ring surface and an arc-shaped washer that cooperates with it to form a spherical anti-loosening nut; it has the advantages of generating resistance by the rebound force of the arc-shaped washer when tightening, effectively resisting vibration force and preventing rotation, and when it is used with a screw, the arc-shaped washer elastically deforms to compensate for the deformation and restore the locking force when the screw is deformed or vibrates and the locking force decreases.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1-5As shown in the figure, the spherical anti-loosening nut with an arc-shaped washer described in this specific embodiment includes a spherical anti-loosening nut body 1. The spherical anti-loosening nut body 1 includes a nut cylinder 11 with open ends. The nut cylinder 11 is provided with an internal thread. The outer side of the nut cylinder 11 is provided with a regular hexagonal facet. The front end of the regular hexagonal facet 12 is provided with an arc-shaped annular facet 13. The front end of the nut cylinder 11 is provided with a protrusion 14. The protrusion 14 is movably fitted with an arc-shaped washer 2 to form a spherical anti-loosening nut.

[0021] Furthermore, such as Figures 1-4 As shown, the front end face of the convex cylinder 14 is an inwardly inclined frustum shape, which matches the front arc surface of the arc-shaped gasket 2.

[0022] Furthermore, such as Figures 1-2 As shown, the center of the nut cylinder 11, the hexagonal facets, and the convex cylinder 14 are on the same straight line and are integrally formed.

[0023] Furthermore, such as Figure 5 As shown, the arc-shaped gasket 2 is made of 65Mn / 60si2MnA spring steel.

[0024] Furthermore, such as Figure 5 As shown, the arc-shaped washer 2 includes a washer 21, and a central hole 22 is provided at the center of the washer 21. The diameter of the central hole 22 is larger than the diameter of the cross-sectional circle of the nut cylinder 11. The top and bottom of the washer 21 are arc-shaped surfaces with an angle of 5°-30°.

[0025] The working principle of this utility model is explained in detail below:

[0026] The distinguishing feature of this design compared to traditional nuts is the use of an arc-shaped washer. The top and bottom of the arc-shaped washer 2 are arc-shaped surfaces with an angle of 5°-30°; the arc-shaped washer is made of 65Mn / 60si2MnA spring steel. The arc-shaped washer combined anti-loosening nut is a type of nut that achieves anti-loosening through its geometric structure, utilizing the self-locking effect between the arc-shaped washer and the nut bolt to enhance its anti-loosening performance.

[0027] The beneficial effects and applications of this utility model are described in detail below:

[0028] The top and bottom of the washer have an arc design of (5°-30°) to combine with the bottom plane of the nut. During installation, mechanical gravity causes the arc-shaped washer to deform and match the nut and the mounting surface.

[0029] (1) When tightened, the rebound force of the arc-shaped gasket generates resistance, effectively resisting vibration and preventing rotation.

[0030] (2) Adaptive supplementation: When the preload decreases due to screw deformation or vibration, the arc-shaped gasket elastically deforms to compensate for the deformation and restore the locking force.

[0031] (3) Ease of installation: No special tools are required; it can be installed using common tools available on the market.

[0032] (4) This product is suitable for fasteners for automobiles, engineering machinery, and rail transit.

[0033] When this design is in use, the spherical washer is flattened when the screw is tightened by gravity, and returns to its spherical state when the screw is loosened. The spherical washer achieves the function of shock absorption and anti-loosening.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
