Description

Technical Field

[0001] This utility model relates to the technical field of shoe soles, and in particular to a puncture-resistant and crack-resistant shoe sole. Background Technology

[0002] Shoes are a tool for protecting our feet from injury. Originally, shoes were used to overcome special circumstances and prevent foot discomfort or injury. Now, shoes improve walking comfort and provide support for the feet. Shoes typically consist of a sole, upper, and laces (or other fastening devices). The sole is usually made of wear-resistant and slip-resistant materials to increase stability and safety while walking. However, current shoe soles are not sufficiently puncture-resistant or crack-resistant, making them easily punctured by sharp objects while walking, potentially causing injury. Utility Model Content

[0003] To improve the puncture resistance of shoe soles, this utility model provides a puncture-resistant and crack-resistant shoe sole to address the problems of existing technologies.

[0004] This utility model provides a puncture-resistant and crack-resistant shoe sole, which adopts the following technical solution:

[0005] A puncture-resistant and crack-resistant shoe sole includes a sole body, a puncture-resistant layer is provided on the lower surface of the sole body, the puncture-resistant layer covers the forefoot and the instep of the sole body, and the edge of the puncture-resistant layer extends to the side of the sole body.

[0006] Preferably, the puncture-resistant layer is a nitrile rubber layer.

[0007] Preferably, the puncture-resistant layer has a Shore hardness of 69A and a tensile strength of 170 kg / cm². 2 It has an elongation of 650%, a C-type tear strength of 80 kg / cm, and a DIN abrasion value of 100 cubic millimeters.

[0008] Preferably, the lower surface of the puncture-resistant layer is provided with a plurality of anti-slip protrusions, which are arranged in multiple rows at intervals.

[0009] Preferably, the lower surface of the anti-slip protrusion is hollow.

[0010] Preferably, the anti-slip protrusions are arranged in a spindle shape, with one end of the anti-slip protrusion embedded between the ends of two adjacent anti-slip protrusions in another row.

[0011] Preferably, the anti-slip protrusions are arranged along the length direction inclined to the sole body.

[0012] Preferably, the lower surface of the heel portion of the sole body is provided with multiple anti-slip grooves.

[0013] Preferably, an aramid fabric layer is provided between the sole body and the puncture-resistant layer.

[0014] Preferably, the puncture-resistant layer has multiple raised ridges on the lower surface near the toe of the sole body, and the raised ridges are arranged along the width direction of the puncture-resistant layer.

[0015] In summary, this utility model provides at least one of the following beneficial technical effects for puncture-resistant and crack-resistant shoe soles:

[0016] By covering the underside of the sole with a nitrile rubber layer and placing an aramid fabric layer between the sole and the puncture-resistant layer, the sole effectively blocks punctures from sharp objects, is less prone to cracking after long-term use, has a longer service life, and provides strong anti-slip performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] This utility model discloses a puncture-resistant and crack-resistant shoe sole, such as... Figure 1-3 As shown, the shoe includes a sole body 1, which can be made of foamed EVA, making the sole lighter and more comfortable. The lower surface of the sole body 1 is provided with a puncture-resistant layer 2, which is made of nitrile rubber. The sole body 1 and the puncture-resistant layer 2 can be fixed together by heat pressing. Nitrile rubber has high hardness and toughness, effectively blocking punctures from sharp objects and is less prone to cracking after long-term use, resulting in a longer service life. Furthermore, the puncture-resistant layer 2 covers the forefoot and instep of the sole body 1, with its edges extending to the sides of the sole body 1, thus providing a large coverage area and better protection for the feet. The puncture-resistant layer 2 has a Shore hardness of 69A, a tensile strength of 170 kg / cm², an elongation of 650%, a C-tear strength of 80 kg / cm², and a DIN abrasion value of 100 cubic millimeters, indicating better abrasion resistance and higher strength.

[0024] In addition, the lower surface of the puncture-resistant layer 2 is integrally formed with multiple anti-slip protrusions 21. The anti-slip protrusions 21 are arranged in a spindle shape and are positioned along the length of the sole body 1, thus increasing the contact between the anti-slip protrusions 21 and the ground when walking, thereby improving friction. Furthermore, the multiple anti-slip protrusions 21 are arranged in multiple rows, with the rows spaced apart. One end of each anti-slip protrusion 21 is embedded between the ends of two adjacent anti-slip protrusions 21 in another row. This allows for a greater number of anti-slip protrusions 21, making them more densely packed and further improving friction. Additionally, the lower surface of the anti-slip protrusions 21 is hollow, which further enhances friction.

[0025] In addition, multiple anti-slip grooves 11 are formed on the lower surface of the heel of the sole body 1, which can improve the anti-slip performance of the heel of the sole body 1. Furthermore, an aramid fabric layer is provided between the sole body 1 and the puncture-resistant layer 2. The aramid fabric layer has higher puncture resistance and can better protect the human foot from being punctured by sharp objects in extreme situations. At the same time, multiple raised ridges 22 are provided on the lower surface of the puncture-resistant layer 2 near the toe of the sole body 1. The raised ridges 22 are arranged along the width direction of the puncture-resistant layer 2, which can improve the friction of the puncture-resistant layer 2 near the toe of the sole body 1.

[0026] The implementation principle of the puncture-resistant and crack-resistant shoe sole of this utility model embodiment is as follows: by covering the lower surface of the shoe sole body 1 with a nitrile rubber layer, and setting an aramid cloth layer between the shoe sole body 1 and the puncture-resistant layer 2, it can effectively block the puncture of sharp objects, and is not easy to crack after long-term use, with a longer service life and strong anti-slip performance.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
