Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to a flexible puncture-resistant shoe sole. Background Technology
[0002] In many work and life scenarios, shoe soles need to be puncture-resistant to protect the feet from sharp objects. Most existing puncture-resistant soles use rigid materials such as steel plates. While these effectively block punctures, they lack flexibility, resulting in lower comfort and restricting normal foot movement. Furthermore, their weight can cause fatigue during prolonged wear. Some flexible puncture-resistant soles struggle to achieve a good balance between puncture resistance and flexibility, failing to meet users' dual needs for comfort and safety. Therefore, we propose a flexible puncture-resistant sole. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a flexible puncture-resistant sole. This invention solves the problem that most existing puncture-resistant soles use rigid materials, such as steel plates. While these materials effectively block punctures from sharp objects, they suffer from poor flexibility, resulting in low comfort and restricted foot movement. Furthermore, their weight can cause fatigue during prolonged wear. Additionally, some flexible puncture-resistant soles struggle to achieve a good balance between puncture resistance and flexibility, failing to meet users' dual needs for comfort and safety.
[0004] This utility model discloses a flexible puncture-resistant shoe sole, comprising a shoe sole body, a fixing groove formed in the middle of the upper end of the shoe sole body, a cushioning layer provided in the fixing groove of the shoe sole body, a puncture-resistant layer provided below the cushioning layer, a first abrasion-resistant layer provided at the end of the puncture-resistant layer away from the cushioning layer, and a second abrasion-resistant layer provided on one side of the first abrasion-resistant layer, the first abrasion-resistant layer and the second abrasion-resistant layer having the same structure, and the puncture-resistant layer being an alternating layer of multiple layers of aramid fiber cloth and TPU film.
[0005] In the above scheme, both the first wear-resistant layer and the second wear-resistant layer have anti-slip textures on the side away from the puncture-resistant layer.
[0006] In the above scheme, the first wear-resistant layer is an ultra-high molecular weight polyethylene layer.
[0007] In the above scheme, the anti-slip texture is a mesh pattern.
[0008] In the above scheme, the buffer layer has multiple elastic protrusions arranged in a matrix on the side away from the puncture-resistant layer.
[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a flexible puncture-resistant sole. When walking, the impact force of the ground first acts on the first and second abrasion-resistant layers. The first and second abrasion-resistant layers disperse the impact force and transfer it to the puncture-resistant layer through a mesh anti-slip texture. The puncture-resistant layer, with its composite structure of aramid fiber cloth and TPU film, not only prevents sharp objects from puncturing the foot, but also further transfers the impact force to the cushioning layer. The cushioning layer and elastic protrusions absorb and buffer the impact force, reducing vibration to the foot and providing a comfortable wearing experience. This type of puncture-resistant sole has a simple structure, good abrasion resistance, and excellent puncture resistance, reducing the overall weight of the sole while effectively improving comfort.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1-3As shown, this utility model is a flexible puncture-resistant shoe sole, including a shoe sole body 1. A fixing groove 2 is formed in the middle of the upper end of the shoe sole body 1. A cushioning layer 3 is provided within the fixing groove 2. The cushioning layer 3 effectively increases the cushioning performance of the shoe sole, thereby improving its comfort. A puncture-resistant layer 4 is provided below the cushioning layer 3, effectively increasing the puncture resistance of the shoe sole. A first abrasion-resistant layer 5 is provided on the end of the puncture-resistant layer 4 away from the cushioning layer 3, effectively increasing the abrasion resistance of the shoe sole. A second abrasion-resistant layer 6 is provided on one side of the first abrasion-resistant layer 5. The first abrasion-resistant layer 5 and the second abrasion-resistant layer 6 have the same structure. The puncture-resistant layer 4 is composed of alternating layers of multilayer aramid fiber cloth and TPU film. The aramid fiber cloth has high strength and high modulus, effectively blocking punctures from sharp objects. The TPU film has good flexibility and abrasion resistance. The films are laminated together using a hot-pressing process, which allows the puncture-resistant layer to maintain a certain degree of flexibility while possessing excellent puncture resistance.
[0017] Both the first wear-resistant layer 5 and the second wear-resistant layer 6 have anti-slip patterns 7 on the side away from the puncture-resistant layer 4, which effectively increases the wear resistance of the sole.
[0018] The first wear-resistant layer 5 is an ultra-high molecular weight polyethylene layer.
[0019] The anti-slip texture 7 is a mesh pattern.
[0020] The buffer layer 3 has multiple elastic protrusions 8 arranged in a matrix on the side away from the puncture-resistant layer 4.
[0021] Specifically, in this invention, when walking on the flexible puncture-resistant sole, the impact force from the ground first acts on the first wear-resistant layer 5 and the second wear-resistant layer 6. The first wear-resistant layer 5 and the second wear-resistant layer 6 disperse the impact force and transfer it to the puncture-resistant layer 4 through the mesh anti-slip texture 7. The puncture-resistant layer, with its composite structure of aramid fiber cloth and TPU film, not only prevents sharp objects from puncturing the foot, but also further transfers the impact force to the cushioning layer 3. The cushioning layer 3 and the elastic protrusions 8 absorb and cushion the impact force, reducing vibration to the foot and providing a comfortable wearing experience.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
