Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. Meanwhile, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0026] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0029] Please also read Figures 1 to 3 The bolt provided by the utility model is now described. The bolt comprises a screw rod 20, a head 10 and a plurality of ridges 30; the head 10 is connected to one end of the screw rod 20, and the connection is rounded; the plurality of ridges 30 are arranged at the connection between the head 10 and the screw rod 20, and each ridge 30 is connected to the screw rod 20 and the head 10; wherein, when the bolt is tightened, the ridges 30 are suitable for being squeezed and clamped together with the parts.

[0030] The beneficial effect of the bolt provided by the utility model is that: compared with the prior art, the bolt provided by the utility model is provided with a plurality of ridges 30 at the connection between the head 10 and the screw rod 20. When the bolt is tightened, the ridges 30 on the bolt and the part are squeezed against each other, causing the surface of the part to deform, thereby causing the ridges 30 to embed into the surface of the part and be clamped with the part, effectively preventing the bolt from rotating and thus not rotating with the nut; therefore, the part can be tightened by rotating the nut with only one tool, and after tightening, loosening due to the self-rotation of the bolt can be effectively avoided.

[0031] like Figure 1 and Figure 2 As shown, in a specific implementation manner of the bolt provided in an embodiment of the utility model, the ridge 30 is in a pyramidal structure, one side is connected to the screw rod 20, and the other side is connected to the head 10, so that the outermost side is an inclined ridge formed by the intersection of two inclined surfaces, so that when in use, it is squeezed with the surface of the part, causing the surface of the part to produce corresponding deformation, so that the ridge 30 is embedded in the surface of the part, so that the bolt and the part are clamped together.

[0032] Specifically, Figure 1 and Figure 2 As shown, in a specific implementation manner of the bolt provided in an embodiment of the utility model, there are at least two convex ribs 30 , and the two convex ribs 30 are symmetrically arranged on both sides of the screw rod 20 .

[0033] More specifically, Figure 1 and Figure 2 As shown, in a specific implementation of the bolt provided in an embodiment of the utility model, there are four ridges 30, and the four ridges 30 are evenly arranged around the screw rod 20, and each ridge 30 is connected to the screw rod 20 and the head 10, so that the bolt and the parts are more firmly connected.

[0034] like Figure 1 and Figure 2 As shown, in a specific implementation manner of the bolt provided in the embodiment of the utility model, the end surface of the head 10 facing away from the screw rod 20 is in a spherical segment shape.

[0035] Further, such as Figure 1 and Figure 3 As shown, in a specific implementation of the bolt provided in an embodiment of the utility model, the head 10 includes a base 11 and a corrosion-resistant layer 12 , the base 11 is connected to the screw rod 20 , and the corrosion-resistant layer 12 is wrapped on the base 11 .

[0036] Specifically, the material of the corrosion-resistant layer 12 is set according to needs. Preferably, the corrosion-resistant layer 12 is a rubber layer, which is directly formed on the surface of the substrate 11 by an injection molding process.

[0037] like Figure 1 and Figure 3 As shown, in a specific implementation manner of the bolt provided in an embodiment of the utility model, an annular groove 111 is opened on the side of the base 11 facing the screw rod 20, one side of the annular groove 111 is connected to the outer edge of the base 11, and the other side is spaced apart from the screw rod 20, and the corrosion-resistant layer 12 on the side of the base 11 facing the screw rod 20 is placed in the annular groove 111, and the corrosion-resistant layer 12 protrudes from the end face of the base 11 facing the screw rod 20.

[0038] It should be noted that the annular groove 111 is provided so that during injection molding, the rubber can be cut off at the annular groove 111, so that the edge of the corrosion-resistant layer 12 is neat and beautiful; the corrosion-resistant layer 12 protrudes from the end face of the base 11 toward the screw 20 side, so that after the bolt is tightened, the corrosion-resistant layer 12 is sealed with the surface of the part, effectively preventing the base 11 from being exposed.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
