Description

Technical Field

[0001] This utility model relates to the technical field of shoe soles, specifically EVA composite material shoe soles. Background Technology

[0002] EVA composite soles are mainly made of ethylene and vinyl acetate copolymer, which has rubber-like elasticity and good softness. They can still maintain good flexibility below 0°C, providing a comfortable wearing experience for the feet and reducing fatigue when walking.

[0003] A search revealed Chinese patent publication number CN218474228U, which discloses a breathable and sweat-wicking EVA shoe sole. The breathable and sweat-wicking EVA shoe sole includes: an EVA shoe sole body; air grooves are formed at both the forefoot and heel of the EVA shoe sole body; a connecting hole is formed between two air grooves; and an exhaust hole is formed on the side of each air groove that is far apart from the other, connecting to the outside. Multiple air inlets are formed between the forefoot and heel of the EVA shoe sole body, and the air inlets are connected to the connecting hole. The breathable and sweat-wicking EVA shoe sole provided by this utility model not only has good breathability and sweat wicking properties and provides cushioning performance, but also promotes airflow.

[0004] However, when wearing existing shoes, only the foot and toes can be fully supported by the sole, while the arch is left unsupported. This means that when the wearer stands, the weight is entirely on the foot and toes, which not only causes discomfort in the arch but also increases foot pain and reduces the comfort of the shoe. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an EVA composite material sole, which solves the problem that when wearing shoes, only the foot and toes can be fully supported by the sole, while the arch is suspended. This causes the wearer to rely entirely on the foot and toes for support when standing, which not only leads to discomfort in the arch area but also increases foot pain and reduces the comfort of the sole.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an EVA composite material shoe sole, comprising a shoe sole and a support pad, wherein an installation groove is provided inside the top surface of the shoe sole, an air bladder is placed inside the installation groove, an air inlet pipe is fixedly installed on the front side wall of the air bladder, and the front end of the air inlet pipe extends through the interior of the front side wall of the shoe sole to the exterior of the shoe sole, and the support pad is slidably connected to the interior of the installation groove, and the material of the support pad is the same as that of the shoe sole.

[0007] Preferably, the two end sidewalls of the mounting groove are provided with limiting grooves, and the two end sidewalls of the support pad are fixedly installed with limiting plastic parts, which are slidably connected to the inside of the limiting grooves, thereby facilitating the limiting of the position of the support pad.

[0008] Preferably, a tension spring is fixedly installed on the upper end of each of the limiting plastic parts, and the upper end of the tension spring is fixedly connected to the upper side wall of the limiting groove, so as to facilitate the downward movement of the support pad that has lost its limiting position and reset it.

[0009] Preferably, the side wall of the air intake pipe is fixedly connected to the inside of the shoe sole, and a sealing plug is sealed inside the front end of the air intake pipe, so as to facilitate the blocking of the air intake pipe and make its interior sealed.

[0010] Preferably, multiple spherical pads are fixedly installed at equal intervals on the top surface of the support pad, and the top surface of the support pad is arc-shaped, so that when supporting the arch of the foot, the sharp edges of the support pad can prevent the wearer from feeling uncomfortable.

[0011] This invention provides an EVA composite material shoe sole. It has the following beneficial effects:

[0012] 1. The EVA composite material sole, when used, can conveniently compress the wearer's arch through the cooperation between the set support pad and the spherical pad, thereby relieving the pressure on the wearer's feet;

[0013] 2. The EVA composite material sole allows for easy adjustment of the height of the support pad through the cooperation between the air bladder and the support pad, thus improving the wearer's comfort. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides an EVA composite material shoe sole, including a shoe sole 1 and a support pad 2. An installation groove 4 is provided inside the top surface of the shoe sole 1, and an airbag 6 is placed inside the installation groove 4. An air inlet pipe 7 is fixedly installed on the front sidewall of the airbag 6, and the front end of the air inlet pipe 7 extends through the interior of the front sidewall of the shoe sole 1 to the outside of the shoe sole 1. The support pad 2 is slidably connected to the interior of the installation groove 4, and the material of the support pad 2 is the same as that of the shoe sole 1. Limiting grooves 5 are provided inside the sidewalls at both ends of the installation groove 4. Limiting plastic parts 9 are fixedly installed on the sidewalls at both ends of the support pad 2, and the limiting plastic parts 9 are slidably connected to the interior of the limiting grooves 5. Tension springs 10 are fixedly installed on the upper ends of the limiting plastic parts 9, and the upper ends of the tension springs 10 are connected to the limiting grooves 5. The upper side wall is fixedly connected, and the side wall of the air inlet pipe 7 is fixedly connected to the inside of the sole 1. The front end of the air inlet pipe 7 is sealed with a sealing plug 8. Multiple spherical pads 3 are fixedly installed at equal intervals inside the top surface of the support pad 2. The top surface of the support pad 2 is arc-shaped. When the wearer wears the shoe body of the sole 1, the position of the support pad 2 can be adjusted according to the arch of the wearer's foot. By inflating or deflating the air bladder 6 through the air inlet pipe 7, the support pad 2 can be easily pushed upward or de-supported, and the support pad 2 can be easily moved downward. The bottom of the support pad 2 can easily support the arch of the foot. Then, the inside of the air inlet pipe 7 is sealed with the sealing plug 8 to enhance the support of the foot and improve the wearer's comfort.

[0021] It should be noted that in this embodiment, when using EVA composite material soles, such as Figure 1-4As shown, when the wearer puts on the shoe body with sole 1, the position of the support pad 2 is adjusted according to the arch of the wearer's foot. The air inlet tube 7 inflates or deflates the air bladder 6, which can easily push the support pad 2 upward or make the support pad 2 lose support, and can easily move the support pad 2 downward. The bottom of the support pad 2 can easily support the arch of the foot. Then, the inside of the air inlet tube 7 is sealed with the sealing plug 8 to enhance the support of the foot and improve the wearer's comfort.
