Description

Technical Field

[0001] The utility model relates to the technical field of shoe materials, in particular to a sole of a puncture-resistant sports shoe. Background Art

[0002] When running or climbing, sports enthusiasts may accidentally step on sharp objects on the ground or on the mountain, which may pierce the soles and injure the soles of their feet. Therefore, the soles of ordinary sports shoes cannot fully guarantee the safety of the wearer. In order to prevent such accidents, people use puncture-proof shoes, which insert puncture-proof metal sheets into the midsole of the shoe to resist the penetration of sharp metal objects and ensure the safety of the wearer. However, the metal in this puncture-proof sole is highly rigid and has weak shock absorption ability. Wearing shoes made of this sole for a long time can easily cause sweat accumulation and fatigue in the feet.

[0003] After the 21st century, with the emergence of lightweight, high-performance fiber materials, ultra-high molecular weight polyethylene fibers and aramid fibers were rapidly used to make the puncture-proof layer of stab-proof insoles. However, these materials all have puncture-proof properties, but they are expensive and have poor air permeability, which cannot meet the requirements of sports enthusiasts for good resilience and quick perspiration in the soles of sports shoes.

[0004] The utility model is made based on this situation. Utility Model Content

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-3 As shown, the sole of a puncture-resistant sports shoe in the utility model comprises an outsole 1 and a midsole 2 from bottom to top, the midsole comprising a buffer layer 21 and a first puncture-resistant layer 22 distributed above the buffer layer 21 and extendedly wrapped by the buffer layer 21, the first puncture-resistant layer 22 being a fabric layer impregnated with a shear-thickening non-Newtonian fluid, and an antibacterial sweat-absorbing layer 3 being provided above the midsole 2; a plurality of first air holes 211 running vertically are provided in the buffer layer 21, and a plurality of second air holes 212 communicating with the first air holes 211 are correspondingly provided on the side walls of the buffer layer 21. In this embodiment, the air permeability of the sole is further increased by providing a plurality of first air holes 211 running vertically and second air holes 212 communicating with the first air holes 211; specifically, the first air holes 211 are evenly distributed on the forefoot portion of the buffer layer 21 on the midsole 2. The forefoot is where people sweat the most during daily activities and is also the place most likely to cause sweat odor in shoes. Arranging the first air hole 211 in the forefoot of the cushioning layer 21 not only improves the deformation resistance of the arch and heel of the sole, but also ensures the sweat absorption and ventilation function of the sole.

[0030] The cushioning layer 21 of the sole of the puncture-resistant sports shoe of the utility model has good shock absorption and rebound effects. A first puncture-resistant layer 22 is provided on the top of the cushioning layer 21 and is wrapped by the cushioning layer 21. The first puncture-resistant layer 22 is a fabric layer soaked in a shear-thickening non-Newtonian fluid. This fabric layer has good air permeability and good puncture-resistant effect, which can prevent sports enthusiasts from accidentally stepping on sharp objects and stabbing their feet when climbing or running. The sole of the utility model has a simple structure and multiple functions, which can fully meet the needs of sports enthusiasts.

[0031] The non-Newtonian fluid has shear thickening properties, and has the special property of being soft at ordinary times and instantly hardening when encountering an impact. Therefore, when encountering a puncture from a foreign object, the non-Newtonian fluid can quickly harden and resist the puncture, playing an anti-puncture role. When the puncture impact is relieved, the non-Newtonian fluid returns to a soft state, and can have both protective performance and flexibility. Therefore, the first anti-puncture layer 22 of the fabric layer impregnated with the shear thickening non-Newtonian fluid has both good air permeability and good anti-puncture effect.

[0032] The fabric layer of this embodiment is a cotton wool tissue, which is soft. After the non-Newtonian fluid penetrates into it, the first puncture-resistant layer remains soft when it does not encounter puncture impact. In addition, the cotton wool tissue has good air permeability and can absorb more shear-thickening non-Newtonian fluid, further improving the puncture-resistant ability of the first puncture-resistant layer 22.

[0033] like Figure 1-3 As shown, the diameter of the first air hole 211 of the utility model is 0.5-2 mm, and the diameter of the second air hole 212 is 0.5-1 mm. By limiting the diameters of the first air hole and the second air hole, the air permeability of the sole is further increased; in order to improve the waterproof performance and deformation resistance of the sole, the first air hole 211 and the second air hole 212 can be filled with activated carbon material.

[0034] The utility model has a second anti-puncture layer 4 between the outer sole 1 and the midsole 2, and the second anti-puncture layer 4 is located below the first air hole 211. This can prevent sharp objects from accidentally piercing the first air hole and affecting the air permeability and waterproof performance of the sole.

[0035] The second puncture-resistant layer 4 is made of aramid cloth or a fabric layer soaked in a shear-thickening non-Newtonian fluid. Aramid unidirectional cloth is used in situations where high strength in a single direction of 0 degrees in the longitude or 90 degrees in the latitude is required, and has a good needle-proof function.

[0036] like Figure 1-3As shown, a waterproof and breathable layer 5 is provided between the antibacterial and sweat-absorbing layer 3 and the first anti-puncture layer 22. The waterproof and breathable layer 5 can not only ensure the breathability of the sole, but also prevent rainwater from penetrating into the antibacterial and sweat-absorbing layer 3 of the sole through the second breathable holes 212 and the first breathable holes 211 when it rains. The specific waterproof and breathable layer 5 is a polytetrafluoroethylene layer.

[0037] like Figure 4 As shown, the antibacterial sweat-absorbing layer 3 is formed by bonding a linen cloth layer 31, an antibacterial layer 32, and an activated carbon layer 33 from top to bottom. The linen layer 31 made of linen as the main material has the properties of sweat absorption, perspiration discharge, air permeability, and radiation resistance. The antibacterial layer 32 is mainly made of latex and nano titanium dioxide and other materials, which can absorb moisture in the linen layer 31 and play an anti-mildew and antibacterial role. The activated carbon layer 33 can further absorb water vapor in the shoe and enhance the air permeability of the sole.

[0038] The cushioning layer 21 of the utility model is a foamed EVA layer or a PHYLON layer. The foamed EVA or PHYLON material has good shock absorption and energy absorption functions, and can prevent foot fatigue caused by long-term exercise. The outsole 1 of the utility model can be selected from a rubber sole, an Oxford sole, a foamed EVA layer, and a PHYLON layer.
