Description

Technical Field

[0001] This utility model relates to the field of rubber shoe sole technology, and in particular to a flexurally resistant rubber shoe sole. Background Technology

[0002] In everyday wear and sports, the flexural strength of shoe soles directly affects the comfort and lifespan of shoes. High-quality flexural rubber soles effectively cushion impacts from the ground and distribute bending stress during frequent walking, running, and jumping, preventing breakage and glue separation due to excessive deformation. These soles not only provide stable support for the feet, reducing the risk of sports injuries, but also improve walking efficiency and reduce wearer fatigue through good resilience. Furthermore, flexural design extends the lifespan of the sole, reducing resource waste and economic costs caused by frequent shoe replacements, which is of great significance for improving the practicality and environmental friendliness of footwear products.

[0003] Traditional rubber shoe soles are mostly made of a single material in one piece or have a simple composite structure. They mainly rely on the elasticity of the rubber itself to achieve bending. Some soles have hard support plates inside, but these support plates are usually fixed and cannot deform in coordination with the bending action of the sole.

[0004] However, existing ordinary rubber soles generally have the problem of not being able to effectively disperse stress during repeated bending, having poor resilience and difficulty in quickly restoring their shape, which leads to easy breakage and glue separation of the sole, seriously affecting the wearing experience and service life. Traditional one-piece molded soles lack stress dispersion structure, and the stress during bending is concentrated at the connection between the forefoot and the arch of the foot, causing cracks to appear in this area after a period of use, reducing walking comfort. Therefore, a bending-resistant rubber sole is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flexural rubber sole, which aims to improve the problems in the prior art where the sole cannot effectively disperse stress during repeated bending, has poor resilience and is difficult to quickly restore its shape, resulting in easy breakage and glue separation of the sole.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexurally resistant rubber sole includes a rubber sole, a wrapping layer at the top of the rubber sole, a spring sheet at the top of the rubber sole, the spring sheet being disposed between the rubber sole and the wrapping layer, an anti-slip layer at the bottom of the rubber sole, a plurality of anti-slip blocks being fixedly connected to the bottom of the anti-slip layer, and a support component being disposed inside the rubber sole.

[0008] As a further description of the above technical solution:

[0009] The support assembly includes multiple support rods, which are evenly distributed in a linear array inside the rubber sole.

[0010] As a further description of the above technical solution:

[0011] The rubber sole has multiple connecting rods inside, and these connecting rods are rotatably connected to the outer walls of the multiple support rods.

[0012] As a further description of the above technical solution:

[0013] The multiple connecting rods are evenly distributed in a linear array inside the rubber sole.

[0014] As a further description of the above technical solution:

[0015] Springs are fitted onto the outer walls of all of the support rods and the connecting rods.

[0016] As a further description of the above technical solution:

[0017] Both ends of the multiple springs are fixedly connected to the inside of the rubber shoe sole.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, a synergistic deformation structure consisting of a spring, a support rod, a connecting rod, and a spring drives the rubber sole and the anti-slip layer to work, achieving efficient dispersion of bending stress and rapid recovery of shape. This solves the problem of ineffective stress dispersion, poor resilience, and difficulty in quickly recovering shape during repeated bending, which leads to easy breakage and glue separation of the sole, thereby improving the service life of the rubber sole.

[0027] 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.

[0028] Reference Figures 1-5 This utility model provides an embodiment of a flexurally resistant rubber shoe sole, comprising a rubber shoe sole 1, a wrapping layer 2 on the top of the rubber shoe sole 1, and a spring piece 3 on the top of the rubber shoe sole 1, the spring piece 3 being disposed between the rubber shoe sole 1 and the wrapping layer 2. When the wearer walks or exercises, causing the shoe sole to bend, the spring piece 3 can quickly undergo elastic deformation. When the shoe sole returns to a flat state, its strong rebound force assists the rubber shoe sole 1 in quickly restoring its original position. An anti-slip layer 4 is provided at the bottom of the rubber shoe sole 1, and multiple anti-slip blocks 5 are fixedly connected to the bottom of the anti-slip layer 4. A support assembly is provided inside the rubber shoe sole 1, the support assembly including multiple supports. Multiple support rods 6 are evenly distributed in a linear array inside the rubber sole 1. Multiple connecting rods 7 are provided inside the rubber sole 1, and the multiple connecting rods 7 are rotatably connected to the outer wall of the multiple support rods 6. The multiple connecting rods 7 are evenly distributed in a linear array inside the rubber sole 1. Springs 8 are sleeved on the outer wall of the multiple support rods 6 and connecting rods 7. The two ends of the multiple springs 8 are fixedly connected to the inside of the rubber sole 1. During the bending process of the sole, the springs 8 undergo compression or stretching deformation as the position of the support rods 6 and connecting rods 7 changes, generating a reverse elastic force to assist the components in quickly returning to their original position, further enhancing the bending resistance and resilience of the sole.

[0029] Working Principle: When using this flex-resistant rubber sole, as the wearer walks or moves, causing the sole to bend, the various components work together to ensure flex resistance and support stability. First, the rubber sole 1 serves as the basic load-bearing structure. The top wrapping layer 2 conforms to the foot, providing comfortable support. The spring plate 3, located between the rubber sole 1 and the wrapping layer 2, uses its own elasticity to assist in deformation recovery when the sole bends, enhancing the sole's resilience. The anti-slip layer 4 and multiple anti-slip blocks 5 at the bottom of the rubber sole 1 increase friction upon contact with the ground, preventing slippage. Meanwhile, multiple support rods 6 inside the rubber sole 1 provide longitudinal support. When the sole bends, these support rods, in conjunction with the multiple connecting rods 7 rotatably connected to its outer wall, move with the sole. The bending process causes rotation, adaptively adjusting the position and dispersing bending stress. Furthermore, the springs 8 on the outer walls of the multiple support rods 6 and connecting rods 7 generate a reverse elastic force due to deformation when the sole bends and the positions of the support rods 6 and connecting rods 7 change. This assists the support rods 6 and connecting rods 7 in returning to their original position, further enhancing the bending resistance and resilience of the sole. This allows the sole to effectively disperse stress and quickly restore its shape during repeated bending, ensuring a comfortable wearing experience and extending the lifespan of the sole. As a result, the bending-resistant rubber sole 1 achieves a stable and durable performance.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
