Description

Technical Field

[0001] The utility model relates to the field of shoe accessories, in particular to a double-hardness rubber-coated upper leather component for heels. Background Art

[0002] The heel, as one of the primary stress points during walking, is the fastest-wearing part of the shoe's sole and plays a crucial role in comfort. Therefore, existing plastic heels, especially those of women's shoes, utilize an auxiliary accessory, commonly known as a top lift or top piece, attached to the heel body to contact the ground.

[0003] Currently, the upper leather of heels is mainly made of high-hardness rubber or other high-hardness elastomer materials, which cannot meet the characteristics of anti-slip, quietness, high wear resistance, etc., and cannot meet the increasingly high standards of the current consumer market;

[0004] Moreover, the existing double-hardness rubber-coated top leather, such as the support body on publication number: CN119423451B, still has the risk of falling off on small heels. The utility model optimizes the structural design of the support body, enhances the bonding strength between the support body and the soft elastomer, and effectively reduces the risk of falling off. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a double-hardness rubber-coated upper leather component for the heel.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: a double-hardness rubber-coated upper leather component for a heel, characterized in that it includes a support body, and a surface of one end of the support body is provided with a plurality of connecting columns for assembly with the heel;

[0007] The surface of the support body is provided with a plurality of through holes; the diameter of the through holes on the side where the support body is connected to the connecting column is larger than the diameter of the through holes on the other end surface; the through holes are stepped holes, and the outer edges of the stepped holes are provided with a plurality of grooves;

[0008] The outer edge of the support body is provided with a serrated edge; the outer edge of the support body is provided with two layers of serrated edges, and the serrations of the upper and lower layers of serrated edges are staggered.

[0009] The support body is made of a rubber-plastic material with a Shore hardness of 85A or above, or a Shore hardness of 60D or above.

[0010] The groove is a fan-shaped groove or a crescent-shaped groove.

[0011] Beneficial effects of the present invention: The present invention provides a double-hardness rubber-coated leather component for the heel, which enhances the bonding strength between the support body and the soft elastic body by optimizing the structural design of the support body, and effectively reduces the risk of falling off.

[0012] The utility model also has the characteristics of simple structure, convenient processing and easy assembly, and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0014] Figure 1 This is a schematic diagram of the structure of the utility model Figure 1 ;

[0015] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 ;

[0016] Figure 3 This is a schematic diagram of the cross-sectional structure of the utility model Figure 1 . DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the embodiments do not limit the present invention in any form.

[0018] like Figure 1-3 As shown in the figure:

[0019] A double-hardness rubber-coated upper leather component for a heel includes a support body 1. A plurality of connecting columns 2 for assembly with the heel are provided on the surface of one end of the support body 1. A serrated edge 4 is provided on the outer edge of the support body 1, and the teeth of the upper and lower layers of the serrated edge 4 are staggered. The purpose of providing the upper and lower layers of the staggered serrated edge 4 is to allow the support body 1 and the soft elastomer to bite into each other, thereby further improving the fusion and firmness.

[0020] The surface of the support body 1 is provided with a plurality of through holes 3. The provision of the through holes 3 increases the contact area between the soft elastic body and the support body 1, thereby improving the fusion effect and the firmness after fusion.

[0021] The through hole 3 is located on the surface of one end of the support body 1 where the connecting column 2 is provided, and the aperture of the through hole 3 is larger than the aperture of the through hole 3 on the other end surface. The through hole 3 is a stepped hole, and a groove rim 31 is provided on the outer edge of the stepped hole. In this embodiment, a stepped hole with a larger aperture at the top and a smaller aperture at the bottom is used, and a plurality of groove rims 31 are provided on the outer edge of the stepped hole. The purpose of using the groove rim 31 is to increase the contact area between the soft elastomer and the support body, and further improve the fusion firmness of the soft elastomer and the support body 1.

[0022] The groove rim 31 is staggered up and down. The purpose of adopting the design of staggered up and down groove rim 31 is to form an asymmetric bite structure, thereby improving the bonding strength between the soft elastic body and the support body 1.

[0023] The support body 1 is made of a material with a Shore hardness of 85A (or Shore hardness 60D) or above. Available materials include rubber-plastic materials or composite modified materials. The preferred materials are CPU, TPU, carbon fiber, PA, PA composite carbon fiber and TPU composite PA. Because the support body 1 plays the role of supporting and connecting the heel, its material must have both a certain toughness to resist impact and a hardness to play a supporting role.

[0024] The utility model provides a double-hardness rubber-coated upper leather component for a heel. The improved support body 1 of the structure is more tightly combined with the soft elastic body, thereby effectively reducing the risk of falling off.

[0025] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
