Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing shoe sole technology, specifically to a shock-absorbing shoe sole. Background Technology

[0002] Chinese Patent Publication No. CN210018050U discloses a shock-absorbing sole and a shoe having the shock-absorbing sole. The shock-absorbing sole includes a bottom layer of the sole and at least one corrugated tube device. The corrugated tube device is distributed on the inner surface of the bottom layer of the sole. The corrugated tube device includes at least one hollow corrugated structure of the shock-absorbing sole. The hollow corrugated structure includes at least two corrugated protrusions of the shock-absorbing sole. One end of the hollow corrugated structure is provided with a shock-absorbing sole on the inner surface of the bottom layer of the sole.

[0003] This invention achieves shock absorption by setting a hollow corrugated structure on the inner surface of the sole. However, because the corrugated tube is prone to displacement or torsion, it cannot provide differentiated cushioning for different areas of the sole (such as the inner weight-bearing area / outer propulsion area). Utility Model Content

[0004] Therefore, in order to address the above problems, this utility model provides a shock-absorbing shoe sole that solves the problem that existing shock-absorbing insoles cannot provide differentiated cushioning for different areas of the sole.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A shock-absorbing shoe sole includes a support layer and a grounding layer arranged from top to bottom. A buffer layer is provided between the support layer and the grounding layer. The buffer layer includes a plurality of inclined elastic pillars. The two ends of each elastic pillar are respectively connected to the lower surface of the support layer and the upper surface of the grounding layer. A triangular buffer cavity is formed between adjacent elastic pillars. Each buffer cavity includes a left cavity and a right cavity respectively provided on both sides of the grounding layer. The bottom angle of the left cavity is different from that of the right cavity.

[0007] Furthermore, both the support layer and the buffer layer are made of polyolefin elastomer.

[0008] Furthermore, the sidewalls of the elastic support are provided with axially extending corrugated folds.

[0009] Furthermore, the lower surface of the support layer is provided with radial reinforcing ribs, and the intersection of each reinforcing rib is located at the top connection of each elastic support.

[0010] Furthermore, the buffer layer is surrounded by an annular sealing air cushion.

[0011] Furthermore, the upper surface of the support layer is provided with a wave-shaped support platform, and the crest of the support platform is aligned with the top of each of the buffer cavities.

[0012] Furthermore, the grounding layer is made of rubber.

[0013] Furthermore, the bottom surface of the grounding layer is provided with anti-slip protrusion groups corresponding to the positions of each of the buffer cavities, and each anti-slip protrusion group includes at least three anti-slip protrusions.

[0014] Furthermore, each of the aforementioned anti-slip protrusions is frustoconical in shape.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses the difference in the bottom angle of the cushioning cavities on both sides of the sole to specifically match the foot pressure distribution. Users can choose different sole types according to their walking habits of walking outward or inward. When the bottom angle of the cushioning cavity is larger, it has better deformation space and a higher degree of deformation, which enhances the cushioning of the foot. When the bottom angle of the cushioning cavity is smaller, the rebound force is greater and the support is better, which is suitable for the side with greater load-bearing capacity.

[0026] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Example:

[0028] like Figures 1 to 3 As shown, a shock-absorbing shoe sole includes a support layer 1 and a grounding layer 2 arranged from top to bottom. A buffer layer 3 is provided between the support layer 1 and the grounding layer 2. Both the support layer 1 and the buffer layer 3 are made of polyolefin elastomer. The grounding layer 2 is made of rubber. The buffer layer 3 includes a plurality of inclined elastic pillars 4. The two ends of each elastic pillar 4 are respectively connected to the lower surface of the support layer 1 and the upper surface of the grounding layer 2. A triangular buffer cavity 5 is formed between adjacent elastic pillars 4. Each buffer cavity 5 includes a left cavity and a right cavity respectively provided on both sides of the grounding layer 2. The bottom angle of the left cavity is different from that of the right cavity.

[0029] By specifically matching the foot pressure distribution through the difference in bottom angle of the cushioning cavities 5 on both sides of the sole, users can choose different sole types according to their walking habits of walking outward or inward. When the bottom angle of the cushioning cavity 5 is larger, it has better deformation space and a higher degree of deformation, which enhances the cushioning of the foot. When the bottom angle of the cushioning cavity 5 is smaller, it has greater rebound force and better support, which is suitable for the side with greater load-bearing requirements.

[0030] The sidewall of the elastic support 4 is provided with axially extending corrugated folds 41; the axial folds 41 absorb vertical impact when compressed, the folds 41 unfold to disperse lateral stress, and the folds 41 reset during the rebound process to delay energy release and reduce foot fatigue.

[0031] The lower surface of the support layer 1 is provided with radial reinforcing ribs 11, and the intersection of each reinforcing rib 11 is located at the top connection of each elastic support 4. The alignment of the intersection of the reinforcing ribs 11 with the top of the elastic support 4 can concentrate the foot pressure to the elastic support 4, disperse the edge stress, and reduce the deformation of the sole.

[0032] The buffer layer 3 is surrounded by an annular sealing air cushion 31. When the annular sealing air cushion 31 is compressed, it squeezes the buffer layer towards the center to enhance the rebound force. When the pressure is released, the air cushion expands to assist the elastic support 4 in resetting. At the same time, it is used to prevent mud / water vapor from entering the cavity.

[0033] The upper surface of the support layer 1 is provided with a wave-shaped support platform 12. The crest of the support platform 12 is aligned with the top of each buffer cavity 5. The alignment of the crest with the top of the buffer cavity 5 enables the impact force to be directly transmitted to the buffer core area, thereby improving the shock absorption effect.

[0034] The bottom surface of the grounding layer 1 is provided with anti-slip protrusion groups 13 corresponding to the positions of each buffer cavity 5. Each anti-slip protrusion group 13 includes three anti-slip protrusions 131. Each anti-slip protrusion 131 is frustoconical. The ground reaction force is gradually attenuated through the anti-slip protrusions 131-buffer cavity 5-elastic support 4 to achieve buffer-anti-slip linkage.

[0035] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
