TECHNICAL FIELD
[0001] The present application relates to the technical field of shoe soles, in particular to a structural anti-skid shoe sole suitable for a no-insole shoe type. BACKGROUND
[0002] The no-insole shoe type is widely used in the fields of sandals, slippers and outdoor leisure shoes due to its lightness and simplicity. The design focus of this type of shoe is the shoe sole, because the shoe sole is a core functional component that directly affects the safety and comfort of the user. With the acceleration of people's life pace and the pursuit of quality life, the market demand for high-performance and multi-functional no-insole shoe soles is increasing. Although the traditional shoe sole design meets the basic anti-skid and wear-resistant requirements to some extent, it still has many shortcomings when dealing with complex and variable ground environments.
[0003] In actual application, in order to improve the anti-skid performance of the shoe sole, the existing technology usually adopts several common means: one is to increase the texture depth or surface friction coefficient of the shoe sole, and the other is to improve the material performance. Specifically, some design schemes increase the contact area with the ground by deepening the shoe sole pattern to enhance the friction; and other schemes focus on developing new wear-resistant materials, such as nano-enhanced rubber, to improve the durability of the shoe sole.
[0004] For the related technologies in the above, although these methods improve the anti-skid performance and durability of the shoe sole to some extent, there are still obvious limitations. The existing no-insole shoe sole assembly process is relatively complicated, lacks structural optimization, and lacks standardized design, resulting in low production efficiency and affecting the market competitiveness of the product. CONTENT OF THE INVENTION

[0008] By adopting the technical scheme, firstly, the upper assembly is pre-assembled with the shoe sole in the factory, then the shoe body is connected with the upper assembly, and the insertion rod is pressed into the clamping groove, at this time, the prism is located in the groove, and the upper assembly and the shoe body are connected through the sealing design of the prism and the groove and the interference fit of the insertion rod and the clamping groove, so that the connection strength between the shoe sole and the shoe body is effectively enhanced, and the safety hazard caused by structure loosening during walking is avoided; the design that the prism is located in the groove forms a seal at the connection between the upper assembly and the shoe body, reduces the risk of moisture penetration, and prolongs the service life of the shoe sole; the close connection between the shoe sole and the shoe body can be realized through simple pressing, the assembly process is simplified, the production efficiency is improved, and the manufacturing cost is reduced; in addition, the interference fit design of the prism and the insertion rod enhances the stability of the connection part, ensures that the shoe sole and the shoe body do not separate during walking, and further improves the wearing experience of the user.
[0009] In a specific embodiment, a plurality of sawtooth anti-skid grooves are formed along the assembly surface circumferentially at the edge of the groove of the upper assembly, and the shoe body is fixed with anti-skid teeth that fit the anti-skid grooves.
[0010] By adopting the technical scheme, the friction between the upper assembly and the shoe body is increased, the front and rear torsional separation of the shoe sole and the shoe body after connection is effectively prevented, the stability of the combination of the shoe sole and the shoe body is improved, and the risk of slipping caused by structure loosening is reduced.
[0011] In a specific embodiment, the bottom surface of the shoe sole is provided with three complementary anti-skid textures, namely main fish scale pattern, honeycomb interlaced texture and fine particle texture, the main fish scale pattern is distributed in the forefoot to midfoot area of the shoe sole, the honeycomb interlaced texture is distributed in the midfoot area, covering an area of 30% of the total area of the shoe sole, and the fine particle texture is distributed in the heel area of the shoe sole, the particles are in the shape of a circular truncated cone, and the larger side of the particles is connected to the shoe sole.
[0012] By adopting the technical scheme, the main fish scale pattern is distributed in the forefoot to midfoot area of the shoe sole, which can provide longitudinal friction to prevent forward and backward sliding; the honeycomb interlaced texture is distributed in the midfoot area, covering an area of 30% of the total area of the shoe sole, which can provide lateral friction to adapt to lateral sliding; the fine particle texture is distributed in the heel area of the shoe sole, which can enhance the friction of the microscopic contact surface and improve the gripping effect on wet and slippery surfaces, making it easy to maintain balance; the complementary anti-skid textures work together to significantly improve the anti-skid performance and stability of the shoe sole under various ground conditions.
[0013] In a specific embodiment, an irregular drainage groove is formed between the three complementary anti-skid textures at the bottom of the shoe sole.
[0014] By adopting the above technical solution, the irregular drainage channels can effectively guide water or other liquids to quickly drain from the space between the sole and the ground, reducing the risk of slipping due to water accumulation and improving anti-slip performance. Especially in rainy or muddy environments, this design can significantly improve the grip of the sole, ensuring the safety of the user; in addition, the drainage channel design can also help remove foreign objects such as gravel from the road surface, further enhancing the stability of the sole.
[0015] In one specific implementation, the system further includes a buffer middle layer located between the sole and the upper assembly layer. The buffer middle layer is connected to both the sole and the upper assembly layer, and pressure dispersion channels are provided inside the buffer middle layer.
[0016] By adopting the above technical solutions, the pressure dispersion channels inside the cushioning midlayer are reasonably designed, which can improve the shock absorption performance of the sole, reduce the impact on the sole of the foot during walking, and improve comfort. In addition, the good connection between the cushioning midlayer and the sole and the upper layer enhances the structural stability of the entire sole system and improves the overall performance and durability of the sole.
[0017] In a specific feasible implementation, the pressure dispersion channel is divided into a longitudinal channel and a transverse channel. The longitudinal channel runs through the forefoot to the heel, and the longitudinal and transverse channels intersect to form a "well" shaped layout. The longitudinal section of the pressure dispersion channel is arched. The pressure dispersion channel located in the forefoot area has a smaller curvature, while the pressure dispersion channel located in the middle of the foot is the main load-bearing area and has a larger curvature.
[0018] By adopting the above technical solutions, the special design of the pressure dispersion channel can effectively alleviate the problem of uneven pressure distribution on the sole of the foot. Specifically, the longitudinal channel runs from the forefoot to the heel, ensuring continuous support during gait. The "well"-shaped layout formed by the intersection of the transverse and longitudinal channels further enhances the stability of the overall structure. Especially in the midfoot area, which is the main load-bearing area, the larger arc design can better disperse concentrated pressure and reduce fatigue caused by long-term walking. In addition, the small arc design in the forefoot area also helps to improve the smoothness of gait transition and reduce sudden changes in foot force.
[0019] In one specific implementation, the buffer middle layer is internally connected to multiple shock-absorbing modules, which are distributed at intervals along the heel to the toe.
[0020] By adopting the above technical solutions, the shock absorption performance of the sole is significantly enhanced, effectively absorbing and dispersing the impact force generated during walking, reducing foot fatigue, and improving wearing comfort. At the same time, the reasonable distribution of the shock absorption modules further optimizes the distribution of foot pressure, reduces discomfort caused by excessive local pressure, and improves the overall wearing experience.
[0021] In one specific embodiment, a plurality of spring-shaped pressure dispersion channels are formed in the cushioning midsole, and the spring-shaped pressure dispersion channels are arranged along one side of the cushioning midsole to the sole.
[0022] By adopting the above technical solution, the plurality of spring-shaped pressure dispersion channels enhance the cushioning performance of the sole, especially during walking, effectively absorbing the impact force from the ground, reducing foot fatigue, effectively absorbing and dispersing the impact force generated during walking, reducing the pressure on the sole, and improving the comfort of walking. At the same time, the spring-shaped pressure dispersion channels are arranged at intervals from the heel to the tip, which can provide appropriate pressure dispersion effect at different parts, further improving the stability and comfort of the sole.
[0023] In one specific embodiment, the cushioning midsole is provided with a spring in each of the spring-shaped pressure dispersion channels, and the spring is arranged along the spring-shaped pressure dispersion channel, and both ends of the spring are connected to the cushioning midsole.
[0024] By adopting the above technical solution, the design of the spring enhances the resilience of the sole, making the rebound after each foot landing more rapid and powerful, further improving the stability of walking.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION
[0036] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The present application will be further described in detail.
[0037] The embodiment of the present application discloses a structural anti-skid sole suitable for a no-liner shoe type.
[0038] Referring to Figure 1 , a structural anti-skid sole suitable for a no-liner shoe type comprises a sole 1, a cushioning midsole 2 and an assembly upper layer 3, the cushioning midsole 2 and the assembly upper layer 3 are both arranged above the sole 1, and the assembly upper layer 3 is arranged above the cushioning midsole 2.
[0039] Referring to Figure 1 and Figure 2The sole 1 features three complementary anti-slip textures: a primary fish-scale pattern 11, a honeycomb interlaced pattern 12, and a fine-grained pattern 13. The primary fish-scale pattern 11 is distributed from the forefoot to the midfoot area of the sole 1. Each fish-scale pattern is a flat, arc-shaped piece, 4mm wide and 1.5mm high, with a radius of 2mm. The fish-scale pattern is 2mm along the walking direction and 3mm laterally, arranged in an alternating pattern to provide longitudinal friction and prevent forward and backward slippage. The primary fish-scale pattern 11 is located in the forefoot for easy turning and drainage. The honeycomb interlaced pattern 12 is distributed in the midfoot area, covering 30% of the total area of the sole 1. The honeycomb hexagonal structure has a diagonal length of 6mm and a depth of 1mm, with a spacing of 1.5mm between each honeycomb group, forming a relatively integral surface structure to provide lateral friction and adapt to lateral slippage. Fine granular texture 13 is distributed in the heel area of the sole 1 to increase stability. The granules are 3mm in diameter and 1mm in height, and are truncated cone-shaped. The larger side of the truncated cone is integrally connected to the sole 1, while the smaller side has a diameter of 1.5mm. The granular texture is evenly distributed, with a center-to-center spacing of 4mm, which enhances the friction of the micro-contact surface. As an "anchor point," it improves the grip of wet and slippery surfaces, making it easier to maintain balance and remove foreign objects such as gravel from the road surface.
[0040] Reference Figure 2 The sole 1 has irregular drainage grooves 14 between three complementary anti-slip textures to ensure rapid drainage on water or mud, reducing the risk of slipping. The drainage grooves 14 are divided into main drainage grooves 141 and auxiliary drainage grooves 142. The main drainage grooves 141 are 5mm wide and 2mm deep. Multiple main drainage grooves 141 are distributed at intervals along the direction from heel to toe, with an 8mm gap between each main drainage groove 141 to ensure that the overall texture is not affected. The auxiliary drainage grooves 142 are designed diagonally along the heel to midfoot area, with a width of 3mm and a depth of 1.5mm. The intersection with the main drainage grooves 141 forms a 1.5mm×1.5mm drainage node.
[0041] Reference Figure 3 The cushioning mid-layer 2 is located at the top of the sole 1 and is integrally set at the top of the sole 1. The cushioning mid-layer 2 is made of low-density foamed polyurethane (PU), with the pore diameter controlled at 0.1-0.3 mm. The uniform foaming improves the elasticity and durability of the material. The cushioning mid-layer 2 has pressure dispersion channels 21 inside. In this embodiment, the longitudinal section of the pressure dispersion channel 21 is arched, with a height of 3 mm and a bottom width of 6 mm, covering the entire sole 1. The longitudinal channel runs through the forefoot to the heel; the transverse channel spacing is 10 mm, intersecting to form a "well" shaped layout. The pressure dispersion channel 21 in the forefoot area has a smaller curvature, increasing the stability of gait transition. The pressure dispersion channel 21 in the midfoot area is the main load-bearing area, with a larger channel cross-section curvature (radius 4 mm) to improve pressure dispersion ability. When walking, the arched structure relieves the concentrated pressure area on the sole, reducing fatigue from prolonged wear.
