Technical Field
[0001] The present application relates to the technical field of shoe soles, and in particular to a recyclable shoe sole. Background Art
[0002] Shoes are essential daily necessities in daily life. As daily necessities commonly used in daily life, shoe soles are seriously consumed. When existing shoe soles are damaged, a large amount of garbage will be generated. Therefore, it is necessary to reduce the amount of sole materials used to reduce the generation of garbage. Utility Model Content
[0003] In order to reduce the amount of sole material used and thus reduce the generation of garbage, the present application provides a recyclable sole.
[0004] The present application provides a recyclable sole, which adopts the following technical solution:
[0005] A recyclable sole comprises a sole body, wherein the sole body comprises an outsole and a wear-resistant layer detachably connected to the bottom surface of the outsole, wherein the upper surface of the outsole is provided with a plurality of mass-reducing grooves, the outsole is an EVA sole, and the wear-resistant layer is made of rubber.
[0006] By adopting the above technical solution and providing a plurality of weight-reducing grooves, the entire sole is relatively lightweight, reducing the burden on the foot and reducing the material used in the sole body, thereby reducing the generation of waste when it is not promptly recycled. Furthermore, since the sole is made of EVA, an environmentally friendly and biodegradable material, it reduces environmental pollution. Since the outsole is made of EVA and the wear-resistant layer is made of rubber, and since the wear-resistant layer is detachably connected to the bottom surface of the outsole, both the outsole and the wear-resistant layer can be removed and recycled, thus reducing the time spent on disassembly.
[0007] Preferably, a groove is provided on the upper surface of the outsole along its own length direction, and a first shock-absorbing part is provided in the groove of the outsole. Several first shock-absorbing parts are arranged at intervals along the length direction of the outsole, and a mass-reducing groove is formed between adjacent first shock-absorbing parts.
[0008] By adopting the above technical solution, by providing a plurality of first shock-absorbing parts, while forming a mass-reducing groove to reduce the mass of the outsole, the plurality of first shock-absorbing parts can effectively reduce shock when the foot is subjected to external impact and when the foot applies pressure to the sole, thereby providing support for the foot.
[0009] Preferably, the first shock-absorbing portion is arranged in a wave shape along the width direction of the outsole.
[0010] By adopting the above technical solution, the first shock-absorbing part is arranged in a wave shape along the width direction of the outsole, which can have a certain stretching margin when subjected to pressure, thereby reducing the possibility of the first shock-absorbing part being broken under pressure.
[0011] Preferably, the outer bottom is provided with a plurality of hollow columns protruding from the inner wall of the groove, and the hollow columns are connected to the first shock-absorbing part.
[0012] By adopting the above technical solution, a hollow column is provided to connect with the first shock absorbing part, thereby providing certain support to the first shock absorbing part to buffer the pressure received.
[0013] Preferably, the outsole is located in the groove and is further provided with a second shock-absorbing portion, the first shock-absorbing portion is provided at the forefoot portion of the outsole, and the second shock-absorbing portion is provided at the arch portion and the heel portion of the outsole, and the second shock-absorbing portion includes a plurality of second shock-absorbing strips provided parallel to the length direction of the outsole and a plurality of third shock-absorbing strips provided perpendicular to the second shock-absorbing strips, and a mass-reducing groove is formed between adjacent second shock-absorbing strips and third shock-absorbing strips or the inner wall of the groove.
[0014] By adopting the above technical solution, usually, the thickness of the sole at the heel is higher than the thickness of the forefoot. Therefore, by providing a second shock-absorbing part, the second shock-absorbing strips and the third shock-absorbing strips are vertically staggered so that the second shock-absorbing part is arranged in a grid, and the support effect that can be brought about is further increased.
[0015] Preferably, a first abutment layer is provided around the inner wall of the groove of the outsole, the first abutment layer is connected to the upper surface of the first shock-absorbing part, and a second abutment layer is provided around the edge of the upper surface of the outsole, the second abutment layer is connected to the first abutment layer.
[0016] By adopting the above technical solution, the first abutting layer and the second abutting layer are provided to facilitate subsequent connection of the upper body.
[0017] Preferably, the wear-resistant layer is protruding with a card block, and the lower surface of the large bottom is provided with a card slot for the card block to be embedded, the card slot includes a plug-in slot and a limit slot located above the plug-in slot, the limit slot is connected to the plug-in slot, and the diameter of the limit slot is larger than the diameter of the plug-in slot; the card block includes a plug connector adapted to the plug-in slot and a limit head provided on the plug connector, the limit head is adapted to be embedded in the limit slot, and the limit head is provided with a deformation slot extending to the plug connector, so that the limit head is deformed and embedded in the limit slot through the plug-in slot.
[0018] By adopting the above technical solution, the limit head is pressed and inserted into the plug-in slot, thereby forcing the limit head to deform. When the limit head is fully inserted into the limit slot, the limit head is restored to its original shape, and the end face of the limit head close to the plug connector abuts against the inner wall of the limit slot close to the plug-in slot, thereby reducing the possibility of the limit head sliding back out of the limit slot, achieving fixation between the wear-resistant layer and the outsole, and when subjected to a large external force, the wear-resistant layer can be removed from the outsole.
[0019] Preferably, the wear-resistant layer is located at one end of the forefoot portion of the outsole and extends to the upper surface of the outsole. The wear-resistant layer is protruding with a connecting piece, and a slot is provided on the upper surface of the outsole. The connecting piece is protruding with an insert that is embedded in the slot, and the connecting piece is used to connect to the upper.
[0020] By adopting the above technical solution, the connection strength between the wear-resistant layer and the outsole can be improved through the setting of the connecting piece, the plug-in block on the connecting piece and the slot on the outsole, and the upper can be connected to protect the upper body at the toe part.
[0021] In summary, the present invention has the following beneficial effects:
[0022] By providing several weight-reducing grooves, the entire sole is relatively lightweight, reducing the burden on the foot and reducing the material used in the sole itself, thereby reducing waste generation when it is not recycled in a timely manner. Furthermore, the sole is made of EVA, an environmentally friendly and biodegradable material, which reduces environmental pollution. Since the outsole is made of EVA and the wear-resistant layer is made of rubber, and the wear-resistant layer is detachably connected to the bottom surface of the outsole, both the outsole and the wear-resistant layer can be removed and recycled, reducing the time spent on disassembly.
