Description

Technical Field

[0001] This utility model relates to the field of steel hook cores, specifically to a lightweight steel hook core. Background Technology

[0002] This utility model relates to the field of footwear components technology, specifically to a steel shank used in shoes to provide support. Its performance directly affects the comfort, structural stability, and overall performance of the shoes, and it has significant application value in the footwear industry.

[0003] In existing technologies, traditional steel shanks are mostly made of a single carbon steel material, which makes them heavy and puts extra burden on the feet when wearing shoes, affecting comfort. At the same time, the assembly process of traditional shanks is not only cumbersome, but the stability of the connection parts of each section of the shank is also poor. During assembly, the parts are also prone to sliding and displacement, affecting the assembly accuracy. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a lightweight steel hook that achieves lightweight while maintaining support strength, thus solving the technical problems of heavy hook weight, uncomfortable wearing, and complicated assembly in the prior art.

[0005] The objective of this utility model is achieved through the following means:

[0006] A lightweight steel hook section includes an intermediate support section and a hook section. The hook ends are located at both ends of the intermediate support section. The intermediate support section includes a carbon steel inner plate and an aluminum alloy outer plate. The carbon steel inner plate is disposed inside the aluminum alloy outer plate. The carbon steel inner plate and the aluminum alloy outer plate are connected by a laser spot welding and stamping composite process. The hook section includes a steel plate, which is connected to the carbon steel inner plate and the aluminum alloy outer plate. The steel plate has an oblong hole inside, and the oblong hole is integrally formed with the steel plate. A wavy groove is provided on the upper end of the steel plate near the carbon steel inner plate, and the wavy groove is integrally formed with the carbon steel inner plate. The inner wall of the oblong hole is provided with anti-slip texture, and the anti-slip texture is integrally formed with the oblong hole.

[0007] Furthermore, serrated anti-slip protrusions are provided on both sides of the steel plate outside the waist-shaped hole, and the serrated anti-slip protrusions are fixedly connected to the steel plate. The serrated anti-slip protrusions are composed of multiple equally spaced trapezoidal blocks, and the serrated anti-slip protrusions improve the anti-slip stability of the steel hook core section.

[0008] Furthermore, positioning protrusions are provided on the center of both sides of the steel plate outside the waist-shaped hole, and the positioning protrusions are fixedly connected to the steel plate. The positioning protrusions are hemispherical and can be directly inserted into the corresponding slots of the shoe sole without the need for additional positioning structures, thus improving assembly efficiency.

[0009] Furthermore, the steel plate has three equally spaced strip holes located between the waist-shaped hole and the wavy groove, and the strip holes are integrally formed with the steel plate. The strip holes are arranged along the length direction of the steel plate.

[0010] Furthermore, the interior of the strip-shaped hole is provided with reinforcing ribs, which are integrally formed with the steel plate. The reinforcing ribs are arranged along the length of the strip-shaped hole, and the strip-shaped hole and the reinforcing ribs play a role in reducing weight.

[0011] Furthermore, the carbon steel inner plate is provided with a nano-ceramic coating on its exterior, and the nano-ceramic coating is connected to the carbon steel inner plate. The nano-ceramic coating improves the protection of the carbon steel and enhances its corrosion resistance.

[0012] The beneficial effects of this utility model are:

[0013] This utility model, through a structure connecting a carbon steel inner plate and an aluminum alloy outer plate, achieves a significant reduction in the overall weight of the hook while ensuring support strength, thus balancing strength and lightweight design. It solves the problems of heavy weight and uncomfortable wear associated with traditional steel hooks. Furthermore, the integrally formed waist-shaped hole in the steel plate of the hook section further reduces weight and facilitates assembly of the hook with other components, optimizing the structure and improving assembly convenience. This addresses the issues of cumbersome assembly and the potential impact of additional weight reduction on strength associated with traditional hooks. The wavy groove integrally formed with the carbon steel inner plate at the upper end of the steel plate enhances the stability of the connection between the hook section and the intermediate support section, improving the overall structural robustness and resolving the problem of easy loosening of the connection between the hook section and the intermediate support section. Finally, the integrally formed anti-slip texture on the inner wall of the waist-shaped hole prevents component slippage and displacement during assembly, ensuring assembly accuracy and stability and resolving the problem of component slippage leading to assembly errors.
