Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically to an EVA shoe sole with a hollowed-out support skeleton structure. Background Technology

[0002] EVA soles are made primarily of ethylene-vinyl acetate copolymer, possessing numerous advantages such as lightweight, cushioning, and corrosion resistance, and are widely used in athletic shoes, casual shoes, and other fields. However, in actual use, the overall softness and internal support of EVA soles decrease significantly after prolonged wear, affecting the overall comfort of the shoe. Furthermore, they cannot be maintained or repaired, presenting shortcomings and hindering long-term support of the sole's internal structure. Now, a novel EVA sole with a hollowed-out support skeleton structure is proposed to address the above-mentioned shortcomings. Summary of the Invention

[0003] The purpose of this invention is to provide an EVA shoe sole with a hollowed-out support skeleton structure to solve the problem mentioned in the background art that it is inconvenient to provide long-term support for the inside of the shoe sole.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an EVA shoe sole with a hollowed-out support skeleton structure, comprising an EVA shoe sole body, an inner cavity provided inside the EVA shoe sole body, an inner support provided inside the inner cavity, a cavity provided inside the inner support, and a support block fixed between the top and bottom of the cavity, grooves provided inside the right sides of both ends of the EVA shoe sole body, a limiting band provided on the right side of the inner support, and connecting thorns fixed at both ends of the limiting band, and connecting rough surfaces fixed at the right sides of both ends of the EVA shoe sole body.

[0005] As a further technical solution of this utility model, connecting rough surfaces are fixed at the four corners of the bottom of the inner cavity, and connecting spike surfaces are fixed at the four corners of the bottom of the inner support.

[0006] As a further technical solution of this utility model, the four sets of connecting rough surfaces are respectively pasted and fixed on the connecting barbed surfaces.

[0007] As a further technical solution of this utility model, the two ends of the limiting band respectively penetrate the interior of the through groove.

[0008] As a further technical solution of this utility model, the connecting barbed surface is pasted and fixed on the connecting rough surface.

[0009] As a further technical solution of this utility model, a bottom pad is provided at the bottom end of the EVA shoe sole body, and the top of the bottom pad is fixed to the bottom of the EVA shoe sole body by adhesive.

[0010] As a further technical solution of this utility model, a second protrusion is fixed at the rear end of the bottom of the pad, and a first protrusion is fixed at the front end of the bottom of the pad.

[0011] As a further technical solution of this utility model, the first protrusion and the second protrusion are fixed in multiple sets at equal intervals at the front and rear ends of the bottom of the base pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up an EVA sole body, inner support, cavity, support block, inner cavity, limiting band, through groove, connecting serrated surface one, connecting rough surface one, connecting serrated surface two, and connecting rough surface two, when the sole is assembled and used, the internal inner support can support the inside of the sole. The forefoot and heel positions are respectively equipped with solid supports to ensure the support effect of the sole. The middle position adopts a hollow structure to ensure a certain degree of softness and improve the wearing feel. At the same time, through the replaceable setting, when the softness of the internal inner support is insufficient, the internal skeleton support can be replaced separately to provide long-term support for the inside of the sole, reducing costs. By incorporating a base pad and an EVA sole body, the EVA sole, when in use, features a base pad fixed to the bottom of the EVA sole body. The rubber base pad provides thicker, more durable protection to the entire bottom of the sole, enhancing its abrasion resistance. By setting up an EVA sole body, a bottom pad, and protrusion one and protrusion two, when the sole is in use, several protrusion one and protrusion two are fixedly set at the front and back positions of the bottom of the bottom pad, which can increase the contact friction between the sole and the ground, making it slip-resistant. At the same time, a drainage groove is formed between two adjacent sets of protrusion one and protrusion two, which can drain water quickly. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides an embodiment: an EVA shoe sole with a hollow support skeleton structure, including an EVA shoe sole body 2, an inner cavity 6 is provided inside the EVA shoe sole body 2, and an inner support 3 is provided inside the inner cavity 6. A cavity 4 is provided inside the inner support 3, and a support block 5 is fixed between the top and bottom of the cavity 4. A through groove 8 is provided inside the right side of both ends of the EVA shoe sole body 2. A limiting band 7 is provided on the right side of the inner support 3, and a connecting thorn surface 10 is fixed at both ends of the limiting band 7. A connecting rough surface 11 is fixed on the right side of both ends of the EVA shoe sole body 2. Connecting rough surfaces 13 are fixed at the four corners of the bottom of the inner cavity 6, and connecting spikes 12 are fixed at the four corners of the bottom of the inner support 3. The four sets of connecting rough surfaces 13 are respectively pasted and fixed on the connecting spikes 12. The two ends of the limiting band 7 pass through the inside of the groove 8, and connecting spikes 10 are pasted and fixed on connecting rough surfaces 11. Specifically, such as Figures 1-3 As shown, the internal support 3 provides support to the inside of the sole. Solid supports are used at the forefoot and heel to ensure effective sole support, while a hollow structure in the middle ensures a certain degree of softness and improves the wearing experience. Furthermore, the replaceable design allows for long-term support of the sole by replacing the internal support frame when the softness of the internal support 3 is insufficient. The limiting strap 7 can be removed from the two sets of grooves 8 inside the right side of the EVA sole body 2 by tearing the connecting serrated surface 10 from the connecting rough surface 11 on the right side of both ends of the EVA sole body 2. Then, the internal support 3 can be removed from the EVA sole body 2 by tearing the four sets of connecting rough surfaces 13 from the connecting serrated surface 12. This allows for quick replacement.

[0017] The bottom of the EVA sole body 2 is provided with a bottom pad 1, and the top of the bottom pad 1 is fixed to the bottom of the EVA sole body 2 by adhesive. Furthermore, the base pad 1 is made of wear-resistant rubber material; Specifically, such as Figure 1 and Figure 4 As shown, by adding a bottom pad 1 to the bottom of the EVA sole body 2, the bottom pad 1 made of rubber can wrap the entire bottom of the sole, thicken and protect it from wear, and improve the wear resistance of the sole.

[0018] The bottom rear end of the bottom pad 1 is fixed with a second protrusion 14, and the bottom front end of the bottom pad 1 is fixed with a first protrusion 9. The first protrusion 9 and the second protrusion 14 are fixed in multiple sets at equal intervals at the bottom front end and the bottom rear end of the bottom pad 1, respectively. Furthermore, bump 2 14 and bump 1 9 are made of wear-resistant rubber material; Specifically, such as Figure 1 and Figure 4 As shown, by fixing several protrusions 9 and 14 at the front and back positions of the bottom of the pad 1, the contact friction between the sole and the ground can be increased, making the shoes slip-resistant. At the same time, a drainage groove is formed between two adjacent sets of protrusions 9 and 14, which can drain water quickly.

[0019] Working Principle: After assembly, the internal support 3 provides support to the inside of the sole. Solid supports are used at the forefoot and heel to ensure effective support, while a hollow structure in the middle provides a degree of flexibility. The replaceable design allows for long-term support by replacing the internal support 3 if insufficient. A rubber pad 1 is fixed to the bottom of the EVA sole body 2, providing thicker, more durable protection against abrasion. Furthermore, several protrusions 9 and 14 are fixed to the front and back of the bottom of the pad 1 to increase friction between the sole and the ground, preventing slippage. Drainage channels are formed between adjacent sets of protrusions 9 and 14 for rapid drainage.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
