Description

Technical Field

[0001] This utility model discloses a shoe sole, and more particularly relates to a double-layer abrasion-resistant shoe sole. Background Technology

[0002] There are many types of materials used for shoe soles, which can be divided into two categories: natural soles and synthetic soles. Natural soles include natural leather, bamboo, wood, etc., while synthetic soles include environmentally friendly rubber, plastics, rubber-plastic composite materials, recycled leather, elastic cardboard, etc. Different materials produce different performance characteristics for shoe soles. Among them, elasticity, pressure resistance, and abrasion resistance can only be improved by changing the material.

[0003] Existing wear-resistant shoe soles typically improve their wear resistance and lifespan through material modification or composite methods. However, relying solely on materials results in varying degrees of wear under different conditions. Therefore, existing shoe soles incorporate various tread patterns and bumps to enhance wear resistance and improve slip resistance. Due to stress distribution, the toe and heel areas experience the greatest wear. During walking, the heel strikes first, followed by the toe, and then the foot is lifted. These areas experience high stress and friction, while the arch experiences less stress and wear. Consequently, after a period of use, the toe and heel areas show severe wear and tear, requiring replacement of the entire sole, while other areas remain relatively intact. Therefore, this application proposes a novel solution: under high stress conditions, switching support mechanisms can reduce sole friction, extend lifespan, and achieve a wear-resistant effect. Utility Model Content

[0004] The purpose of this invention is to provide a double-layer wear-resistant shoe sole in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer abrasion-resistant shoe sole, comprising a sole, the sole comprising an upper sole and a lower sole, the lower sole having thickened abrasion-resistant blocks at the forefoot and heel, the abrasion-resistant blocks comprising a first abrasion-resistant block and a second abrasion-resistant block, the first abrasion-resistant block and the second abrasion-resistant block being slidably connected to an abutment block, the first abrasion-resistant block and the second abrasion-resistant block being provided with a support member, the support member having a groove for accommodating the movement of the abutment block, the groove having a tension spring for pulling the abutment block back to its original position, the first abrasion-resistant block and the second abrasion-resistant block being detachably connected to an expansion component for protecting the sole and rubbing against the ground.

[0006] Preferably, the expansion assembly includes an elastic expansion bag that is snapped onto the rear end of the abutment block along with the first and second wear-resistant blocks. The bottom of the expansion bag is provided with a wear-resistant layer that contacts the ground, and the wear-resistant layer is thickened.

[0007] Preferably, the abutment block is provided with an extrusion member for pushing and squeezing the expansion bag to deform and force the wear-resistant layer to protrude.

[0008] Preferably, the extrusion member is rotatably connected to the abutment block, and the slide groove is inclined.

[0009] Preferably, the first wear-resistant block and the second wear-resistant block are provided with slots for accommodating the embedded expansion bag, and the expansion bag is provided with elastic inserts on both sides for embedding the slots.

[0010] Preferably, the expansion bags are spaced apart, and the bottom, the first wear-resistant block and the second wear-resistant block are provided with a number of protruding ridges. The expansion bag is located between two protruding ridges, and the expansion bag and the protruding ridges are staggered in height.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By using this device, when walking on rough, sloping ground or gravel, to avoid slipping, the body's center of gravity is lowered, and the toes and heels bear greater force. When moving forward and rubbing, the sole moves forward while the ground remains stationary. The mutual force between the two pushes the abutment block to move, causing the abutment block to move along the groove of the support component. This stretches the tension spring and drives the expansion component, causing the expansion bag to expand and push out the wear-resistant layer to contact the ground. This reduces the direct friction between the sole and the ground, reduces sole wear, and increases the lifespan of the sole. Even after the expansion bag and abutment block are worn out, the lifespan can still be increased by the friction between the sole itself and the ground, thus improving the wear resistance.

[0015] A double-layer abrasion-resistant sole, such as Figures 1-5As shown, the shoe includes a sole, which comprises an upper sole 1 and a lower sole 2. The lower sole 2 has thickened abrasion-resistant blocks located at the ball of the foot and heel. These abrasion-resistant blocks include a first abrasion-resistant block 3 and a second abrasion-resistant block 4. An abutment block 5 is slidably connected to the first abrasion-resistant block 3 and the second abrasion-resistant block 4. A support member 6 is provided on the first abrasion-resistant block 3 and the second abrasion-resistant block 4. The support member 6 has a groove 7 for accommodating the movement of the abutment block 5. A tension spring 8 is provided within the groove 7 to pull the abutment block 5 back to its original position. A detachable connection is made between the first abrasion-resistant block 3 and the second abrasion-resistant block 4 to protect the sole and maintain contact with the ground. The friction expansion component includes an elastic expansion bag 9 that snaps onto the rear end of the abutment block 5, where the first wear-resistant block 3 and the second wear-resistant block 4 are located. The bottom of the expansion bag 9 has a thickened wear-resistant layer 10 that contacts the ground. The abutment block 5 has a pressing member 11 for pushing and squeezing the expansion bag 9 to deform and force the wear-resistant layer 10 to protrude. When walking, if the foot slips, or if the ground is sloping or has a lot of gravel, it is easy to slip, requiring careful walking. The body's center of gravity is relatively downward, resulting in greater force on the sole of the shoe. Simultaneously, when the force is high and the sole moves, the relative friction between the sole and the ground is high, leading to greater wear. Using this device, when moving and experiencing high friction, the two areas of the sole with the greatest force—the ball of the foot and the heel—will experience more severe friction. This greater friction can drive the abutment block 5 to move, simultaneously pulling and deforming the tension spring 8. The abutment block 5 moves along the groove 7 of the support member 6 of the first wear-resistant block 3 and the second wear-resistant block 4, and drives the expansion component. The abutment block 5 moves and pushes the extrusion member 11 to move, squeezing the expansion bag 9. The expansion bag 9 is squeezed at the position where it is embedded in the first wear-resistant block 3 and the second wear-resistant block 4, and the other parts cannot expand. The internal gas rushes out and pushes the wear-resistant layer 10 to be supported and directly contact the ground. This supports the bottom 2 a certain distance, reducing the contact between the bottom 2, the first wear-resistant block 3 and the second wear-resistant block 4 and the ground, reducing the friction between the bottom 2, the first wear-resistant block 3 and the second wear-resistant block 4 and the ground, reducing the wear of the bottom 2, the first wear-resistant block 3 and the second wear-resistant block 4, and improving the service life. Secondly, when the force is even and normal during normal walking, the expansion bag 9 and the wear-resistant layer 10 will not move. They will only rub against each other through the material of the bottom 2, the first wear-resistant block 3 and the second wear-resistant block 4. When the center of gravity increases, the force on the bottom increases, and the contact force with the ground increases, the friction increases, the wear-resistant layer 10 will wear down. Under normal circumstances, only the bottom 2, the first wear-resistant block 3, and the second wear-resistant block 4 will rub against each other, thus achieving automatic switching to adapt to different situations, reducing overall wear and increasing service life. Correspondingly, to improve its wear resistance, it can not only rely on the material, but also improve the overall wear resistance through the structure, which is more practical than the existing replacement method.

[0016] The extrusion part 11 is rotatably connected to the abutment block 5, and the slide groove 7 is inclined. When the slide groove 7 is inclined, the abutment block 5 will move from the highest point to the lowest point along the slide groove 7, which increases the degree of protrusion and thus plays a supporting role, reducing the contact friction between the lower sole 2, the first wear-resistant block 3 and the second wear-resistant block 4 and the ground. Since the first wear-resistant block 3, the second wear-resistant block 4 and the support part 6 are made of hard material, and the upper sole 1 has sufficient pressure resistance, when walking, it can ensure that it does not affect the feet, and at the same time, it can provide sufficient support for the abutment block 5 and the expansion bag 9, ensuring that the walking weight will not affect the movement of the abutment block 5, and also ensuring that the expansion bag 9 and the abutment block 5 can play the role of supporting the sole. The expansion bags 9 are spaced apart. The bottom 2, the first wear-resistant block 3 and the second wear-resistant block 4 are provided with several protruding ridges 14. The expansion bag 9 is located between two protruding ridges 14. The expansion bag 9 and the protruding ridges 14 are staggered in height. Because of the staggered arrangement, under normal conditions, the protruding ridges 14 and the abutment block 5 are in direct contact with the ground, while the wear-resistant layer 10 of the expansion bag 9 is in an embedded state and does not rub directly against the ground. When the force increases and the sole moves, the abutment block 5 pushes the expansion bag 9 back and forth, preventing it from expanding upwards. Instead, it pushes the wear-resistant layer 10 downwards, making it more prominent than the ridge 14. This supports the undersole 2, the first wear-resistant block 3, and the second wear-resistant block 4, reducing their friction with the ground, increasing their service life and reducing replacement frequency, thus saving costs. Furthermore, the undersole itself is made of a high-wear-resistant material, which is hot-pressed and molded from styrene-butadiene rubber. It has high wear resistance. Even if the wear-resistant layer is worn flat, the undersole 2, the first wear-resistant block 3, and the second wear-resistant block 4 can still maintain their service life and strength when in contact with the ground.

[0017] The first wear-resistant block 3 and the second wear-resistant block 4 are provided with slots 12 for accommodating the expansion bag 9. The expansion bag 9 is provided with elastic inserts 13 on both sides for embedding into the slots 12. Finally, the expansion bag 9 is compressed and embedded by the elasticity of the inserts 13. When the expansion bag 9 is severely worn and damaged, it is released and the inserts 13 can be manually compressed and pulled out for replacement. At the same time, the entire first wear-resistant block 3, the second wear-resistant block 4 and the abutment block 5 can be replaced individually. Thus, when the sole of the foot is worn too much and other parts are intact, replacement can be done to save costs. It can be installed and removed by simple snap-fit, which is consistent with the expansion bag 9. Alternatively, other snap-fit ​​structures in the existing technology can also be used.
