Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a multi-layer air cushion sole. Background Art

[0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it refers only to the outsole. The common properties of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to adapt to the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it must cooperate with the midsole to have a braking effect when changing feet while walking to avoid slipping and easy to stop.

[0003] Traditional soles use air cushions to enhance the support and cushioning effect of the soles. The most common structure is that the entire sole is set as an air cushion structure, but in actual preparation, it is found that the preparation process is more complicated. And when using it, it is found that if an air cushion structure is set at the arch of the foot, the force exerted by the foot on the sole is not large. The air cushion structure at the arch of the foot cannot improve the support and cushioning effect to a certain extent, and it will increase the manufacturing cost. Based on this, how to efficiently set the air cushion structure to achieve the best support and cushioning application effect of the sole is particularly important. Utility Model Content

[0004] The utility model provides a multi-layer air cushion sole, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the utility model to solve its technical problem is:

[0006] A multi-layer air cushion sole comprises an inner sole and an outer sole. At least two layers of air cushions are arranged on the inner sole. The width of the air cushion located in the upper layer is greater than that of the air cushion located in the lower layer. Guide strips are arranged at the bottom ends of both sides of the air cushion located at the top of the inner sole. Notches for displacement of the air cushion and guide grooves for displacement of the guide strips are arranged on the inner sole. A spring is arranged at the bottom end of the guide strip. Different air cushions are connected and positioned by connecting blocks. The air cushion comprises a wrapping layer, an arched rubber block and a foam layer. The bottom end of the arched rubber block is bonded to the foam layer. A ventilation channel is arranged on the foam layer. The ventilation channel is divided into a horizontal channel and a vertical channel. The horizontal channel is connected with the vertical channel.

[0007] A better technical solution: the air cushion is provided with three layers.

[0008] A preferred technical solution: a plurality of guide strips are provided.

[0009] A preferred technical solution: two or four guide strips are provided.

[0010] A better technical solution: a built-in support block is arranged at the bottom end of the spring.

[0011] A preferred technical solution: the built-in support block is made of carbon fiber.

[0012] A better technical solution: the inner sole is divided into a forefoot area and a heel area.

[0013] A preferred technical solution: multiple layers of air cushions are distributed in the heel area.

[0014] A preferred technical solution: an air cushion is distributed in the forefoot area.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model improves the supporting and buffering effect of the insole by setting multiple layers of air cushions, thereby ensuring comfort during wearing. After the air cushion is deformed, the guide strip will squeeze the spring; the guide strip and the guide groove cooperate to ensure that the top air cushion is always located on the sole, ensuring the installation effect of the air cushion.

[0022] like Figure 1-Figure 2 As shown, a multi-layer air cushion sole comprises an inner sole 1 and an outer sole 2. At least two layers of air cushions 3 are arranged on the inner sole 1. The width of the air cushion 3 located in the upper layer is greater than that of the air cushion 3 located in the lower layer. Guide strips 4 are arranged at the bottom ends of both sides of the air cushion 3 located at the top of the inner sole 1. The inner sole 1 is provided with notches for displacement of the air cushion 3 and guide grooves 5 for displacement of the guide strips 4. A spring 6 is arranged at the bottom end of the guide strip 4. Different air cushions 3 are connected and positioned by a connecting block 31. The air cushion 3 comprises a wrapping layer 32, an arched rubber block 33, and a foam layer 34. The bottom end of the arched rubber block 33 is bonded to the foam layer 34. A ventilation channel 35 is arranged on the foam layer 34. The ventilation channel 35 is divided into a horizontal channel and a vertical channel. The horizontal channel and the vertical channel are interlinked. One end of the spring 6 is connected to the bottom end of the guide strip 4, and the other end is connected to the built-in support block 7.

[0023] The multi-layer air cushion 3 sole in the utility model is cushioned and supported by the multi-layer air cushion 3. The arched rubber block 33 in the single air cushion 3 structure squeezes the foam layer 34 of the bottom layer when it is stressed. Due to its structural design, the two sides of the rubber block are more easily deformed, thereby squeezing the foam layer 34, which can improve the comfort to a certain extent. When the air cushion 3 is deformed, it will squeeze the air permeable channel 35, which can improve the gas flowability to a certain extent. When running, since the air cushion 3 is subjected to a relatively large force, the spring 6 is squeezed by the guide bar 4 to improve the cushioning effect. At the same time, the guide bar 4 is always in the guide groove 5 and moves along the guide groove 5 to prevent the air cushion 3 at the top from detaching. If the air cushion 3 at the top does not detach, the air cushion 3 below it will also be restricted in the sole and will not detach from the sole. The connecting block 31 facilitates the connection and positioning between different air cushions 3.

[0024] Furthermore, the air cushion 3 is provided with three layers.

[0025] Furthermore, a plurality of guide bars 4 are provided.

[0026] Furthermore, two or four guide bars 4 are provided.

[0027] Furthermore, a built-in support block 7 is provided at the bottom end of the spring 6 .

[0028] Furthermore, the built-in support block 7 is made of carbon fiber.

[0029] Furthermore, the inner sole 1 is divided into a forefoot area 10 and a heel area 20 .

[0030] Furthermore, the multi-layer air cushion 3 is distributed in the heel area 20 .

[0031] Furthermore, an air cushion 3 is distributed in the forefoot area 10 .

[0032] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still fall within the scope covered by the present invention.
