Description

Technical Field

[0001] This utility model relates to the field of washers, and in particular to a robust saddle-shaped washer. Background Technology

[0002] Saddle-shaped washers are generally used in applications requiring anti-loosening properties. Their curved design provides a force to the bolt after installation, increasing the friction between the nut and bolt. Typically, a saddle-shaped washer has a wavy lateral projection, with two bends: one in the center and the other at the edge. Both bends pass through the central hole, resulting in limited force-bearing capacity at the bends. The bend at the center distributes force laterally, making it less prone to damage. However, the bend at the edge, where force is applied along the washer's direction, is more susceptible to bending and may exceed its plastic deformation limit during transport and storage, leading to damage.

[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a robust saddle-shaped washer. This utility model is achieved through the following technical solution:

[0005] A robust saddle-shaped washer includes a central portion and an edge portion. An edge portion is smoothly fixed on both sides of the central portion. A central hole is provided on the central portion. The central portion is curved, and the edge portion is also curved. The edge portion includes a curved section connected to the central portion. The difference between the width of the central portion and the diameter of the central hole is less than the width of the curved section.

[0006] In the above technical solution: the central part and the edge part together constitute the main body of the saddle-shaped washer; the central hole is used to make way for the bolt; the central part is curved, and the edge part is also curved, and the two are combined to form a saddle shape; the requirement for the width of the curved section makes the width of the curved section large, and the ability to withstand lateral forces strong.

[0007] A further feature of this invention is that the edge portion further includes a horizontal segment, which is fixedly connected to the side of the curved segment away from the center portion.

[0008] In the above technical solution: the setting of the horizontal section allows the deformation of the edge to be smooth through the sliding between the horizontal section and the mounting plane, avoiding bending of the edge beyond the plastic deformation limit due to the end of the edge getting stuck with the mounting plane.

[0009] A further feature of this invention is that the bottom surface of the horizontal segment has a rounded corner away from the edge of the curved segment.

[0010] In the above technical solution, the rounded corners are used to further reduce the possibility of the horizontal section end getting stuck with the mounting plane.

[0011] A further feature of this invention is that the central portion is circular.

[0012] In the above technical solution, the central part is circular, which makes the outer edge of the central part smooth and reduces the possibility of scratching the operator during use.

[0013] A further feature of this invention is that the projection of the central hole onto the horizontal plane is elliptical.

[0014] In the above technical solution, the projection of the central hole on the horizontal plane is elliptical, making it less likely for the bolt to get stuck when placed in the central hole.

[0015] This utility model discloses a robust saddle-shaped washer, which, compared with the prior art:

[0016] This invention, by setting a central part and an edge part, enables the curved section at the edge part to withstand greater lateral force, thereby reducing the possibility of bending damage during transportation.

[0017] This invention also reduces the possibility of the gasket being bent and damaged during installation by setting a horizontal section at the edge. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0023] like Figure 1-3As shown, this utility model proposes a robust saddle-shaped washer, comprising a central portion 10 and an edge portion 20. An edge portion 20 is smoothly fixed on both sides of the central portion 10. A central hole 101 is provided on the central portion 10. The central portion 10 is curved, and the edge portions 20 are also curved. Each edge portion 20 includes a curved section 201 connected to the central portion 10. The difference between the width of the central portion 10 and the diameter of the central hole 101 is less than the width of the curved section 201. Specifically, the central portion 10 has a symmetrical structure, specifically, it is symmetrical about the curved position.

[0024] like Figure 1-3 As shown, this utility model proposes a robust saddle-shaped washer, wherein the edge portion 20 further includes a horizontal segment 202, which is fixedly connected to the side of the curved segment 201 away from the center portion 10. The curved segment 201 is symmetrically arranged, and the plane of symmetry of the curved segment 201 is not vertical.

[0025] like Figure 1-3 As shown, the present invention proposes a saddle-shaped washer with a rounded corner 202a on the bottom surface of the horizontal section 202 away from the edge of the curved section 201.

[0026] like Figure 1-3 As shown, the present invention proposes a robust saddle-shaped washer, wherein the central part 10 is circular.

[0027] like Figure 1-3 As shown, the present invention proposes a robust saddle-shaped washer, wherein the projection of the central hole 101 on the horizontal plane is elliptical.

[0028] The working principle of this utility model is as follows:

[0029] Place this utility model on the mounting surface;

[0030] After passing the bolt through the center hole, screw it into the threaded hole on the mounting surface.

[0031] When the bolt presses against the center of the washer;

[0032] The bending point in the center is subjected to force, which is then transmitted to the edges.

[0033] When the curved section at the edge is subjected to force, the horizontal section moves accordingly. Since the end of the horizontal section remains horizontal, the end of the horizontal section will not get stuck.

[0034] The edge is deformed, and the deformed part of this invention applies force to the bolt to prevent loosening.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
