Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to an EVA shoe sole with high shock resistance and comfort. Background Technology

[0002] EVA soles are made primarily of ethylene-vinyl acetate copolymer (EVA), and are characterized by their lightweight, softness, and slip resistance. They are widely used in footwear products such as athletic shoes and slippers.

[0003] Existing patent application number: CN202421606654.4 A lightweight EVA shoe sole includes a sole body and an elastic reinforcement. The sole body has a horizontally arranged movable groove with a rearward opening at the heel position. The elastic reinforcement is arranged along the top, one side wall, and the bottom of the movable groove. When the elastic reinforcement is under pressure, the distance between the top and bottom positions of the elastic reinforcement and the side closest to the opening of the movable groove gradually decreases. After the pressure is released, the elastic reinforcement returns to its original shape.

[0004] The aforementioned patent describes an EVA sole. EVA soles provide excellent resilience through their closed-cell structure to meet the needs of cushioning and shock absorption. However, their elasticity is fixed and it is difficult to adjust the elasticity according to individual foot feel. Their adaptability is poor and it is difficult to meet the needs of different user groups. Therefore, we propose an EVA sole with high shock absorption and comfort to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an EVA shoe sole with high shock resistance and comfort to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an EVA shoe sole with high shock resistance and comfort, comprising an adjustable shoe sole structure, wherein the adjustable shoe sole structure comprises a shoe sole body, an air cushion structure, an inflation valve and a valve cap, wherein the air cushion structure is provided inside the shoe sole body, and an inflation valve is installed at the rear of the heel of the shoe sole body, the inflation valve being connected to the air cushion structure, and a valve cap being threaded onto the interface surface of the inflation valve.

[0007] Preferably, the inflation valve is an embedded, concealed design.

[0008] Preferably, the airbag cushioning structure includes a rear airbag, a middle airbag, a front airbag, and a connecting tube. The rear airbag is located in the heel area inside the main body of the sole, and the rear airbag is connected to an inflation valve. The middle airbag is located in the arch area inside the main body of the sole, and the front airbag is located in the forefoot area inside the main body of the sole. Connecting tubes are provided between the rear airbag and the middle airbag, and between the middle airbag and the front airbag for connection.

[0009] Preferably, the rear airbag, middle airbag, and front airbag are all filled with foam.

[0010] Preferably, a rubber layer is attached to the outer edge of the sole body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention features an adjustable sole structure. By unscrewing the valve cap and connecting an air pump to the inflation valve, gas is pumped into the airbag cushioning structure. As the inflation volume increases, the airbag cushioning structure expands, increasing the internal air pressure and enhancing the support elasticity. Conversely, as the inflation volume decreases, the support elasticity weakens. Finally, the valve cap is reattached to complete the elasticity adjustment. The elasticity of the sole body can be adjusted according to the user's needs, improving the wearing experience.

[0012] This invention incorporates an airbag cushioning structure inside the sole, where the rear airbag provides elastic support to the heel, the middle airbag provides elastic support to the arch of the foot, and the forefoot airbag provides elastic support to the forefoot. During wear, each airbag can distribute pressure through deformation, thereby providing excellent shock absorption. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the overall top sectional structure of this utility model; Figure 2 This is a top cross-sectional view of the airbag buffer structure in this utility model; Figure 3 This is a top view of the inflation valve in this utility model.

[0014] In the diagram: Adjustable sole structure-1, sole body-11, air cushioning structure-12, rear air cushion-121, middle air cushion-122, front air cushion-123, through tube-124, foam cotton-125, inflation valve-13, valve cap-14, rubber layer-15. Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1-2This utility model provides an EVA shoe sole with high shock resistance and comfort, including an adjustable shoe sole structure 1. The adjustable shoe sole structure 1 includes a shoe sole body 11, an air cushion structure 12, an inflation valve 13, and a valve cap 14. The air cushion structure 12 is provided inside the shoe sole body 11. An inflation valve 13 is installed at the rear of the heel of the shoe sole body 11. The inflation valve 13 is connected to the air cushion structure 12. The valve cap 14 is threaded onto the interface surface of the inflation valve 13.

[0017] Specifically, by setting an adjustable sole structure 1, when adjusting the elasticity, first unscrew the valve cap 14, then connect the air pump to the inflation valve 13 to pump air into the airbag cushioning structure 12. When the inflation volume increases, the airbag cushioning structure 12 expands, the internal air pressure increases, and the support elasticity is enhanced. Conversely, when the inflation volume decreases, the support elasticity weakens. Finally, put the valve cap 14 back on to complete the elasticity adjustment. The elasticity of the sole body 11 can be adjusted according to the user's needs to improve the wearing experience.

[0018] Please see Figure 3 This utility model provides an EVA shoe sole with high shock resistance and comfort. The airbag cushioning structure 12 includes a rear airbag 121, a middle airbag 122, a front airbag 123, and a connecting tube 124. The rear airbag 121 is provided in the heel area inside the shoe sole body 11, and the rear airbag 121 is connected to the inflation valve 13. The middle airbag 122 is provided in the arch area inside the shoe sole body 11, and the front airbag 123 is provided in the forefoot area inside the shoe sole body 11. The connecting tube 124 is provided between the rear airbag 121 and the middle airbag 122, and between the middle airbag 122 and the front airbag 123 for connection.

[0019] The inflation valve 13 is an embedded and hidden design to prevent the inflation valve 13 from being exposed and causing inconvenience to movement, and to improve the aesthetics.

[0020] To further explain, the rear airbag section 121, the middle airbag section 122 and the front airbag section 123 are all filled with foam 125. The foam 125 provides basic support for the airbag and prevents the airbag from collapsing and affecting the feel of the foot.

[0021] Among them, a rubber layer 15 is attached to the outer edge of the sole body 11. The rubber layer 15 can enhance the surface strength of the sole body 11 and prevent sharp objects from piercing and damaging the airbag cushioning structure 12.

[0022] Specifically, an airbag cushioning structure 12 is set inside the main body 11 of the sole. The airbag cushioning structure 12 consists of a rear airbag 121, a middle airbag 122, and a front airbag 123 located in three different positions. The rear airbag 121 provides elastic support for the heel, the middle airbag 122 provides elastic support for the arch of the foot, and the front airbag 123 provides elastic support for the forefoot. During wear, each airbag can disperse pressure through deformation, thereby providing good shock absorption.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
