High-resilience shock-absorption wear-resistant combined shoe sole

Abstract

The utility model relates to the technical field of shoes, and provides a high-resilience shock-absorption wear-resistant combined sole which is characterized in that a buffer body is embedded in a fixing hole, so that the buffer body and a sole body are tightly combined. The buffer body comprises the elastic block and the supporting block, so that the supporting block is in contact with the ground; the elastic blocks elastically abut against the foot roots of the human body.

The sole material and design directly affect the wear resistance and comfort of the shoes, etc. Now people's requirements for the sole are no longer limited to showing fashionable elements, but also pay more attention to the functionality and health of the sole. At present, dress shoes can meet the basic anti-slip and wear-resistant requirements, but there is still room for improvement in terms of comfort.

[0003] In the prior art CN221410551U, a shock-absorbing and rebound sole for children's basketball shoes is provided. By arranging an auxiliary insole structure inside the sole, after the first insole, the second insole, the limiting block and the spring arranged therein cooperate with each other, a good limiting, shock-absorbing and rebound effect can be achieved. By arranging a shock-absorbing and light-weight structure with a hollow groove at the bottom of the sole, the lightness and shock-absorbing and supporting effects of the shoes are further improved.

[0004] However, the adoption of the spring structure design not only increases the complexity of the process and the cost, but also with the use time and repeated stress, and coupled with factors such as sweating during the human body movement process, the spring will oxidize, the material characteristics will change, so that the elastic ability becomes weak, reducing the comfort of people wearing. Summary of the Utility Model

[0005] Based on the above background, the purpose of the utility model is to provide a high-elasticity shock-absorbing and wear-resistant combined sole, which can effectively avoid the structural failure caused by the spring stress fatigue, realize that the sole has excellent rebound shock-absorbing and wear-resistant functions, and greatly improve the comfort of the dress shoe sole.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-elasticity shock-absorbing and wear-resistant combined sole, comprising: a sole body, a fixing hole is penetrated through the root of the sole body; a buffer body, embedded in the fixing hole, wherein, the buffer body includes elastic filling beads, an elastic block and a support block arranged on the elastic block, one end of the elastic block is located inside the sole body, one end of the support block is located at the bottom side of the sole body, a buffer cavity is formed inside the elastic block, and each of the elastic filling beads is filled in the buffer cavity; a wear-resistant structure, arranged on the bottom side of the sole body.

[0008] Further, the fixing hole includes a first hole section and a second hole section communicating with the first hole section.

[0009] Further, the buffer body further includes a first abutting edge, which is circumferentially arranged at one end of the elastic block away from the support block, and the first abutting edge abuts against one end of the first hole section away from the second hole section.

[0010] Further, the buffer body further includes a second abutting edge, which is circumferentially arranged at one end of the support block away from the elastic block, and the second abutting edge abuts against one end of the second hole section away from the first hole section.

[0011] Further, the buffer body further includes a curved elastic sheet, which is curved and arranged on a side surface of the second abutting edge facing the elastic block, and there is a deformation gap between the curved elastic sheet and the second abutting edge.

[0012] Further, the wear-resistant structure includes a first wear-resistant sheet and a second wear-resistant sheet.

[0019] (4) Circumferentially arrange a second abutting edge at one end of the support block to close one end of the second hole section, avoiding stones or impurities from entering the fixing hole during walking or running, and improving the sealing performance of the sole. At the same time, arrange a curved elastic sheet with a curved shape on one side of the second abutting edge, which can further enhance the rebound shock absorption function of the sole.

[0033] In one embodiment, please combine Figures 1 to 6The present application provides a high-resilience, shock-absorbing, and wear-resistant combined sole 100, comprising: a sole body 10, wherein a fixing hole 13 is penetrated through the root of the sole body 10; a buffer body 20, which is embedded in the fixing hole 13, wherein the buffer body 20 comprises elastic filling beads 23, an elastic block 21, and a support block 22 arranged on the elastic block 21, wherein one end of the elastic block 21 is located on the inner side 11 of the sole body 10, and one end of the support block 22 is located on the bottom side 12 of the sole body 10, and a buffer cavity 211 is provided in the elastic block 21, wherein each elastic filling bead 23 is filled in the buffer cavity 211; and a wear-resistant structure 30, which is arranged on the bottom side 12 of the sole body 10.

[0034] The above-mentioned high-rebound shock-absorbing and wear-resistant combined sole 100 embeds the buffer body 20 in the fixing hole 13, so that the buffer body 20 and the sole body 10 are tightly combined. Since the buffer body 20 includes an elastic block 21 and a support block 22, the support block 22 is used to contact the ground; and the elastic block 21 is used to elastically resist the heel of the human body. Since the elastic block 21 has a buffer cavity 211 inside, the elastic block 21 can be deformed into the buffer cavity 211 by force during walking or running, and effectively absorbs the vibration during walking or running. Since the buffer cavity 21 is filled with elastic filling beads 23, after effectively absorbing the vibration, it can rebound in time to generate a boosting force. Compared with the sole 100 with a traditional spring structure, it can effectively avoid structural failure caused by fatigue due to force, and realize that the sole 100 has excellent rebound shock absorption. In addition, the bottom side 12 of the sole body 10 is provided with a wear-resistant structure 30, which can improve the wear resistance of the sole 100. With such a design, the sole 100 has excellent rebound, shock absorption and wear resistance, and the comfort of the formal shoe sole 100 is greatly improved.

[0035] It should be explained that the elastic filling beads 23 refer to bead structures with certain elastic functions, such as hollow plastic beads, hollow rubber beads, etc. The elastic filling beads 23 are filled in the buffer cavity 211 in a variety of ways, such as sending the popcorn raw materials into the silica gel material by steam, and then thermally expanding and cooling them. E-TPU popcorn is made by expanding the volume of TPU particles 5-10 times in a very short time. This material has excellent elasticity and can fully absorb vibrations during walking or running. After absorbing the vibrations, it can rebound immediately to generate a boost. In addition, it is very light and there will be no fatigue and weight bearing during long-term exercise.

[0036] It should also be explained that the wear-resistant structure 30 refers to a structure with certain wear-resistant properties, for example: it can be made of a super wear-resistant rubber material formula, and the wear resistance index can reach a wear mark ≦3mm.

[0037] In addition, the sole body 10 can be made of rubber-plastic foam material, which is environmentally friendly, lightweight, and has the advantages of good cushioning, shock resistance, and chemical corrosion resistance, further increasing the overall rebound and shock absorption effect of the sole 100.

[0038] Furthermore, please refer to Figure 5 , the fixing hole 13 includes a first hole section 131 and a second hole section 132 communicating with the first hole section 131. The cross-sectional area of the first hole section 131 is larger than that of the second hole section 132. The elastic block 21 is embedded in the first hole section 131, and the support block 22 is embedded in the second hole section 132. It can be seen that by designing the fixing hole 13 as the first hole section 131 and the second hole section 132 with different cross-sectional areas, it is not only convenient for the fixed installation of the elastic block 21 and the support block 22; but also similar to the T-shaped structure design, which is convenient for the more compact combination between the buffer body 20 and the sole body 10, and avoids the two being easily separated and causing structural failure.

[0039] It should be explained that the shapes of the first hole section 131 and the second hole section 132 can be designed to adapt to the shapes of the elastic block 21 and the support block 22 respectively. And the cross-sectional area of the first hole section 131 is larger than that of the second hole section 132, which can prevent the entire buffer body 20 from falling out of the fixing hole 13.

[0040] Meanwhile, positioning posts 221 can be arranged on the circumference of the support block 22, and positioning grooves matching the positioning posts 221 are arranged on the hole wall of the second hole section 132. This further improves the combination between the buffer body 20 and the sole body 10.

[0041] In one embodiment, please refer to Figure 4 , the buffer body 20 further includes a first abutting edge 24. The first abutting edge 24 is circumferentially arranged at one end of the elastic block 21 away from the support block 22, and the first abutting edge 24 abuts against one end of the first hole section 131 away from the second hole section 132. It can be seen that by circumferentially arranging the first abutting edge 24 at one end of the elastic block 21, the first abutting edge 24 can be used to close one end of the first hole section 131, avoiding the edge of the first hole section 131 directly contacting the root of the human body and causing discomfort. At the same time, it is also convenient for the buffer body 20 to be closely combined with the sole body 10, further improving the structural stability.

[0042] In one embodiment, please refer to Figure 6 , the buffer body 20 further includes a second abutting edge 25. The second abutting edge 25 is circumferentially arranged at one end of the support block 22 away from the elastic block 21, and the second abutting edge 25 abuts against one end of the second hole section 132 away from the first hole section 131. It can be seen that by circumferentially arranging the second abutting edge 25 at one end of the support block 22, one end of the second hole section 132 is closed, preventing stones or impurities from entering the fixing hole 13 when walking or running, and improving the sealing performance of the sole 100.

[0043] It should be explained that the first abutting edge 24 and the second abutting edge 25 can jointly form an upper and lower clamping structure, so that the buffer body 20 is stably clamped at the upper and lower ends of the fixing hole 13.

[0044] Specifically, the first abutting edge 24, the elastic block 21, the supporting block 22 and the second abutting edge 25 are of an integrated structure.

[0045] In one embodiment, please refer to Figure 6 , the buffer body 20 further includes a curved elastic sheet 26. The curved elastic sheet 26 is curved and arranged on the side surface of the second abutting edge 25 facing the elastic block 21. There is a deformation gap between the curved elastic sheet 26 and the second abutting edge 25. It can be seen that by arranging the curved elastic sheet 26 which is curved on one side surface of the second abutting edge 25, the rebound shock absorption function of the sole 100 can be further improved.

[0046] Among them, the curved elastic sheet 26 can be formed on the second abutting edge 25 by injection molding.

[0047] It should be explained that in order to avoid affecting the sealing performance between the second abutting edge 25 and one end of the second hole section 132 due to the introduction of the curved elastic sheet 26, a space for avoiding the curved elastic sheet 26 can be provided at one end of the second hole section 132.

[0048] In one embodiment, the wear-resistant structure 30 includes a first wear-resistant sheet 31 and a second wear-resistant sheet 32. The first wear-resistant sheet 31 is arranged on the bottom side 12 of the sole body 10 and surrounds the outer periphery of the fixing hole 13. The second wear-resistant sheet 32 is arranged at the sole of the foot part on the bottom side 12 of the sole body 10. It can be seen that the wear-resistant performance is further improved.

[0049] In one embodiment, please refer to Figure 1 , it further includes a buffer sheet 40. The buffer sheet 40 is arranged at the sole of the foot on the inner side 11 of the sole body 10.

[0050] Furthermore, please refer to Figure 1 and Figure 2 , an installation groove 14 is provided at the sole of the foot on the inner side 11 of the sole body 10, and the buffer sheet 40 is arranged in the installation groove 14. It can be seen that the installation stability of the buffer body 20 is improved.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
