Although various aspects of embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically noted.

[0025] The term "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0026] In addition, for the purpose of convenience and brevity, detailed descriptions of well-known functions and structures incorporated in the application are omitted. It will be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described herein, embody the principles of the application and fall within the spirit and scope of the application.

[0027] Referring to Figures 1-5 In the embodiment of the present application, a shoe sole anti-skid structure comprises a shoe sole 1, a front heel 101, a rear heel 102, a midsole 103, an air bag 4, a pressing cavity 3, and an anti-skid assembly.

[0028] Specifically, referring to Figure 2 , Figure 3 , Figure 4 , comprising:

[0029] The shoe sole 1 is divided into the front heel 101, the rear heel 102, and the midsole 103.

[0030] The air bag 4 is arranged in an inner groove of the rear heel 102 and is in communication with a pressing cavity 3 formed in the midsole 103.

[0031] The anti-skid assembly is arranged in the pressing cavity 3 and is in sliding connection with the pressing cavity 3. When the pressing cavity 3 is filled with gas, the anti-skid assembly is driven to move and penetrates through the midsole 103 to contact the ground.

[0032] It should be noted that when a human body walks, the front heel 101 and the rear heel 102 are usually in contact with the ground, and the midsole 103 is far away from the ground.

[0033] In detail, in the embodiment, the shoe sole anti-skid structure is used, when the user walks, the main weight of the human body is concentrated on the rear foot, the air bag 4 arranged at the rear heel 102 is compressed after being subjected to the pressure, the ground impact force can be buffered, at the same time, the compressed gas in the air bag 4 is delivered into the extrusion cavity 3, so that the air pressure in the extrusion cavity 3 is increased, the anti-skid assembly is driven to move relative to the extrusion cavity 3 and penetrate the midsole 103, the anti-skid assembly is in contact with the ground, the contact area of the shoe sole 1 and the ground is increased, so that the anti-skid effect of the shoe sole 1 is effectively improved, and when the anti-skid assembly is retracted, the accumulated snow can be removed.

[0034] When the shoe sole 1 is in contact with the ground for an instant when the user walks, the anti-skid assembly is moved relative to the extrusion cavity 3 to be in contact with the ground, the friction force between the shoe sole 1 and the ground is increased, and when the shoe sole 1 is lifted, the pressure on the air bag 4 disappears, and the anti-skid assembly is quickly reset.

[0035] Preferably, a plurality of anti-skid protrusions 2 are arranged on the front heel 101 and the rear heel 102, the anti-skid protrusions 2 can adopt a plurality of special-shaped structures, mainly for the anti-skid effect of the shoe sole 1.

[0036] Preferably, the anti-skid protrusions 2 are made of rubber.

[0037] In another embodiment, the anti-skid protrusions 2 can be made of polyurethane.

[0038] The gap is formed between the adjacent two anti-skid protrusions 2, the use amount of rubber is reduced, and the light weight effect is achieved.

[0039] Preferably, a plurality of through grooves 9 are formed on the midsole 103 and are in communication with the inner side of the extrusion cavity 3.

[0040] Please refer to Figure 4 and Figure 5 The anti-skid assembly comprises a lifting plate 6 which is sealingly and slidingly arranged in the extrusion cavity 3, and the bottom of the lifting plate 6 is provided with a plurality of anti-skid nails 7 which are slidingly matched with the through grooves 9.

[0041] Further comprising a spring 8 which is arranged in the extrusion cavity 3, one end of the spring 8 is fixedly connected with the lifting plate 6, and the other end is fixedly connected with the inner bottom of the extrusion cavity 3.

[0042] Preferably, the air bag 4 and the extrusion cavity 3 are in communication through the inner side of the guide hole 5.

[0043] It should be noted that: in the initial state, the end of the anti-skid nail 7 away from the lifting plate 6 is flush with the midsole 103, preventing rain and snow from being brought into the extrusion cavity 3 when walking, and automatically cleaning the rain and snow stuck in the gap between the anti-skid nails 7.

[0044] In detail, when the air bag 4 is compressed, the gas in the air bag 4 is transported into the extrusion cavity 3 through the guide hole 5, and the increase of the gas in the extrusion cavity 3 increases the pressure in the extrusion cavity 3, which generates extrusion force on the lifting plate 6, so that the lifting plate 6 moves in the extrusion cavity 3 relative to the inner wall of the extrusion cavity 3. During the movement, the lifting plate 6 and the inner wall of the extrusion cavity 3 are always in sealed sliding, preventing the gas in the extrusion cavity 3 from flowing out to the outside through the gap between the lifting plate 6 and the inner wall of the extrusion cavity 3. When the lifting plate 6 moves, the anti-skid nail 7 moves synchronously. In the initial state, the spring 8 is in a natural state, and after being extruded by the lifting plate 6, the spring 8 is compressed to store elastic potential energy, so that the anti-skid nail 7 passes through the through slot 9 and abuts against the ground, increasing the contact area between the sole 1 and the ground, and increasing the friction between the sole 1 and the ground, so as to improve the skid resistance of the sole 1.

[0045] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
