Description

Technical Field

[0001] This utility model relates to the field of shoe sole production technology, specifically to high-elastic dual-density shoe soles. Background Technology

[0002] The sole is the part of the shoe that contacts the ground and plays a crucial role in the entire footwear product. Functionally, it first and foremost bears the heavy responsibility of supporting the body weight, distributing pressure on the body, and ensuring stability when walking or standing. Just like the foundation of a tall building, a stable sole can guarantee foot comfort and safety.

[0003] In the prior art, Chinese Patent Publication No. CN221554805U discloses a color-changing shoe sole, including an anti-slip layer, a sole base layer, and a force-sensitive color-changing layer. The anti-slip layer, the sole base layer, and the force-sensitive color-changing layer all have the same upper shape and are arranged parallel to each other from bottom to top. The anti-slip layer is integrally formed with the sole base layer. The force-sensitive color-changing layer is a thin film layer of uniform thickness. When subjected to force, it forms a rough structure with cracks and creases, becoming opaque, so that the color of the sole changes when the wearer walks. It does not require spraying color-changing material directly onto the sole base layer. Simply spraying a force-sensitive color-changing layer onto the sole base layer is enough to make the color of the sole change when the wearer walks and is subjected to force. It can achieve a good color-changing effect without relying on temperature and light, is not prone to color-changing failure, and can maintain a good color-changing effect for a long time.

[0004] Based on the above materials, since the sole needs to have good elasticity to cushion the ground reaction force and reduce the impact on the feet and joints, it also needs to have sufficient support strength to ensure stability and comfort during walking or exercise. Existing technologies rely solely on materials to achieve elasticity, which is insufficient in meeting the requirements of high elasticity. Therefore, we propose a high-elasticity dual-density sole. Utility Model Content

[0005] The purpose of this invention is to provide a high-elasticity dual-density sole to address the problem mentioned in the background art that, as the sole needs to have good elasticity to cushion the ground reaction force and reduce the impact on the feet and joints, it also needs sufficient support strength to ensure stability and comfort during walking or exercise. Existing technologies rely solely on materials to achieve elasticity, which is insufficient in meeting the requirements for high elasticity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-elastic dual-density shoe sole, comprising a shoe sole body, wherein the top outer wall of the shoe sole body is provided with a first adhesive groove corresponding to the bottom of the shoe body, the shoe sole body is provided with an elastic structure for enhancing the elasticity of the shoe sole, the elastic structure includes a first elastic buffer cavity and a second elastic buffer cavity provided inside the shoe sole body, and the inner walls of the first elastic buffer cavity and the second elastic buffer cavity are provided with elastic buffer blocks, and the bottom of the shoe sole body is provided with an anti-slip structure.

[0007] Furthermore, the main body of the sole is made of thermoplastic polyurethane elastomer rubber, and the interior of the main body of the sole is provided with an elastic fiber reinforcement network made of high-strength elastic fibers to enhance the elasticity and density of the main body of the sole.

[0008] Furthermore, the first elastic buffer cavity is provided corresponding to the forefoot part of the main body of the shoe sole, and the second elastic buffer cavity is provided corresponding to the heel part of the main body of the shoe sole. The thickness of the second elastic buffer cavity is greater than the thickness of the first elastic buffer cavity, and both the first elastic buffer cavity and the second elastic buffer cavity are filled with highly elastic silicone gel.

[0009] Furthermore, the elastic buffer block is hemispherical in shape, and the elastic buffer block is provided on the inner wall of both the first elastic buffer cavity and the second elastic buffer cavity, and the elastic buffer blocks are equidistantly distributed.

[0010] Furthermore, the anti-slip structure includes an anti-slip layer bonded to the bottom of the shoe sole, and the bottom of the anti-slip layer is provided with a first anti-slip pattern and a second anti-slip pattern. A limiting protrusion is fixedly installed on the top of the anti-slip layer, and a second bonding groove corresponding to the bottom of the main body of the shoe sole is opened on the top of the anti-slip layer.

[0011] Furthermore, the anti-slip layer is correspondingly provided with the main body of the shoe sole, and the anti-slip layer is made of high-density polypropylene material, and the second adhesive groove is attached to the bottom of the main body of the shoe sole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This high-elastic dual-density sole features a first and second elastic cushioning cavity inside the sole body, with elastic cushioning blocks on the inner walls of the cavities, and is filled with high-elasticity silicone gel. This greatly enhances the elasticity of the sole. During walking or exercise, the ground reaction force is absorbed and dispersed by the synergistic effect of the elastic cushioning cavity, elastic cushioning blocks, and silicone gel. This effectively cushions the ground reaction force, reduces the impact on the feet and joints, lowers the risk of sports injuries, and provides users with an excellent comfort experience.

[0014] 2. The main body of the sole is made of thermoplastic polyurethane elastomer rubber, with an internal elastic fiber reinforcement network made of high-strength elastic fibers. This not only improves the elasticity of the sole but also enhances its overall density and structural strength. This allows the sole to withstand greater pressure while maintaining excellent elasticity, ensuring stability during walking or exercise, and preventing it from easily deforming or being damaged due to prolonged stress, thus extending the lifespan of the sole.

[0015] 3. The anti-slip structure significantly improves the anti-slip performance of the sole. The anti-slip layer is made of high-density polypropylene, with different shapes of first and second anti-slip patterns on the bottom. It provides reliable friction under various surface conditions. The "U"-shaped first anti-slip pattern is evenly distributed on the outer side of the bottom of the anti-slip layer, increasing the anti-slip effect at the edges; the V-shaped second anti-slip pattern is evenly distributed in the middle of the bottom of the sole, strengthening the grip in the middle. Whether walking on dry, wet, or slippery surfaces, it can effectively prevent slipping and ensure the safety of the user.

[0016] 4. The anti-slip layer and the main body of the sole are firmly connected through the cooperation of limiting protrusions and limiting grooves and the setting of the second bonding groove. This connection method not only ensures that the anti-slip layer will not easily fall off, but also enhances the overall structural stability of the sole to a certain extent. Furthermore, when the anti-slip layer is worn to a certain extent and needs to be replaced, it can be replaced in a timely manner, providing users with a more comprehensive and high-quality wearing experience.

[0024] 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.

[0025] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: a high-elastic dual-density shoe sole, including a shoe sole body 1, a shoe sole body 1, a first adhesive groove 101 corresponding to the bottom of the shoe body is opened on the top outer wall of the shoe sole body 1, an elastic structure for enhancing the elasticity of the shoe sole is provided inside the shoe sole body 1, the elastic structure includes a first elastic buffer cavity 3 and a second elastic buffer cavity 4 opened inside the shoe sole body 1, and elastic buffer blocks 5 are provided on the inner walls of the first elastic buffer cavity 3 and the second elastic buffer cavity 4, the shoe sole body 1 is made of thermoplastic polyurethane elastomer rubber material, and high-strength elastic fibers are provided inside the shoe sole body 1. The interwoven elastic fiber reinforcement network is used to enhance the elasticity and density of the sole body 1. The first elastic buffer cavity 3 is set corresponding to the forefoot part of the sole body 1, and the second elastic buffer cavity 4 is set corresponding to the heel part of the sole body 1. The thickness of the second elastic buffer cavity 4 is greater than that of the first elastic buffer cavity 3. Both the first elastic buffer cavity 3 and the second elastic buffer cavity 4 are filled with highly elastic silicone gel. The elastic buffer block 5 is hemispherical and is set on the inner wall of both the first elastic buffer cavity 3 and the second elastic buffer cavity 4. The elastic buffer blocks 5 are evenly distributed.

[0026] When the user walks or exercises wearing shoes equipped with this highly elastic dual-density sole, the pressure on the foot is transmitted to the sole body 1. First of all, the sole body 1 is made of thermoplastic polyurethane elastomer rubber material and an elastic fiber reinforcement network formed by the interweaving of high-strength elastic fibers inside, which will initially buffer and disperse the pressure. Relying on the elasticity of the material itself and the toughness of the fiber network, it plays a certain role in support and buffering. As the pressure further acts, the first elastic buffer cavity 3 corresponding to the sole of the foot and the second elastic buffer cavity 4 corresponding to the heel start to play a key role. Since when a person walks, the sole of the foot and the heel are the main stress points, and the pressure borne by the heel is relatively greater, the thickness of the second elastic buffer cavity 4 is greater than that of the first elastic buffer cavity 3. When pressure is applied, the hemispherical elastic buffer blocks 5 in the elastic buffer cavity will deform, and at the same time, the highly elastic silicone gel filled in the cavity will also flow and deform with the change of pressure. The elastic buffer blocks 5 and the silicone gel work together to evenly disperse the pressure throughout the buffer cavity, absorb a large amount of ground reaction forces. After the pressure is released, the elastic buffer blocks 5 and the silicone gel quickly return to their original state, preparing for the next pressure impact, thus efficiently buffering the ground reaction forces and reducing the impact on the foot and joints.

[0027] Embodiment 2: On the basis of Embodiment 1, an anti-slip structure is also disclosed, and its specific structure is as follows: An anti-slip structure is provided at the bottom of the sole body 1. The anti-slip structure includes an anti-slip layer 2 adhesively connected to the bottom of the sole, and the bottom of the anti-slip layer 2 is provided with a first anti-slip pattern 6 and a second anti-slip pattern 7. A limiting convex block 201 is fixedly installed on the top of the anti-slip layer 2, and a second bonding groove 202 corresponding to the bottom of the sole body 1 is opened on the top of the anti-slip layer 2. The anti-slip layer 2 is arranged corresponding to the sole body 1, and the anti-slip layer 2 is made of high-density polypropylene material. The second bonding groove 202 is in fit with the bottom of the sole body 1. The cross-section of the first anti-slip pattern 6 is designed in a "匚" shape, and the first anti-slip pattern 6 is evenly distributed on the outer side of the bottom of the anti-slip layer 2 at equal intervals. The cross-section of the second anti-slip pattern 7 is designed in a V shape, and the second anti-slip pattern 7 is evenly distributed at the middle position of the bottom of the sole body 1 at equal intervals. The cross-section of the limiting convex block 201 is designed in a T shape, and the limiting convex block 201 is evenly distributed on the side of the anti-slip layer 2 where it fits the bottom of the sole body 1, and a limiting groove 102 corresponding to the limiting convex block 201 is opened at the bottom of the sole body 1.

[0028] During walking, the anti-slip structure activates when the sole contacts the ground. Anti-slip layer 2 is made of high-density polypropylene, a material with good wear resistance and a certain degree of friction. The first anti-slip pattern 6 and the second anti-slip pattern 7 on the bottom of anti-slip layer 2 are designed for different stress areas and walking conditions. The "U"-shaped first anti-slip pattern 6 is evenly distributed on the outer side of the bottom of anti-slip layer 2. When the foot turns or experiences lateral force during walking, the outer first anti-slip pattern 6 increases the contact area and friction between the sole and the ground, preventing the foot from sliding outwards and enhancing the anti-slip effect of the sole edge. The V-shaped second anti-slip pattern 7 is evenly distributed in the middle of the bottom of the main sole 1. The middle part is the main stress point during walking. The V-shaped pattern provides strong friction in the vertical direction. When the foot propels forward, the V... The textured pattern allows for better grip on the ground, preventing the sole from sliding forward. Furthermore, the anti-slip layer 2 is firmly connected to the sole body 1 via the cooperation of limiting protrusions 201 and limiting grooves 102, as well as the second adhesive groove 202. The limiting protrusions 201 have a T-shaped cross-section and are equidistantly distributed on the side of the anti-slip layer 2 that adheres to the bottom of the sole body 1, tightly engaging with the limiting grooves 102 at the bottom of the sole body 1 to prevent displacement of the anti-slip layer 2 during use. Simultaneously, the second adhesive groove 202 further enhances the connection stability between the anti-slip layer 2 and the sole body 1, enabling the anti-slip layer 2 to stably perform its anti-slip function, providing reliable safety for users walking on various ground conditions. Moreover, the anti-slip layer 2 can be replaced promptly when it wears down to a certain extent.
