TECHNICAL FIELD

[0001] The present application relates to the field of shoe soles, in particular to a high-elasticity shoe sole with air cushions. BACKGROUND

[0002] The shoe sole is an important part of the shoe, which plays a crucial role in protection, support, comfort, functionality, etc.

[0003] In the prior art, the shoe sole includes air cushions, and an installation groove for installing the shoe sole is formed on the shoe sole. The air cushions are fixed in the installation groove by means of adhesion. The adhesion is prone to aging and failure. The air cushions are also prone to displacement or falling off under long-term dynamic load. Moreover, the air cushions are difficult to replace after damage, resulting in the entire shoe sole being scrapped. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the installation stability of the insole in the shoe sole, the present application provides a high-elasticity shoe sole with air cushions.

[0005] The present application provides a high-elasticity shoe sole with air cushions, which adopts the following technical solution:

A clamping groove is formed on the groove wall of the installation groove. An elastic flange is arranged on the surface of the air cushion in contact with the installation groove.

[0007] By adopting the above technical solution, the elastic flange is inserted into the clamping groove, which increases the contact area of the air cushion and the midsole. When the air cushion is inflated and expanded, the outer surface of the air cushion and the flange are pressed against the groove side wall of the installation groove and the clamping groove. The friction between the air cushion and the installation groove is large, which improves the installation stability of the air cushion. Moreover, the air cushion is not fixedly connected with the midsole, which facilitates the disassembly and replacement of the air cushion.

[0008] Optionally, the clamping groove is formed on the groove side wall of the installation groove, and the elastic flange is arranged on the surface of the air cushion close to the groove side wall of the installation groove.

[0009] By adopting the above technical solution, the elastic flange is inserted into the clamping groove, which can fix the air cushion and prevent the air cushion from falling out of the installation groove, further improving the installation stability of the air cushion.

[0010] Optionally, a guide slope is formed on the surface of the elastic flange close to the clamping groove. The distance between the guide slope and the groove side wall of the clamping groove increases in the direction of the air cushion being loaded into the installation groove.

[0011] By adopting the above technical solution, the guide slope on the elastic flange guides the elastic flange to be clamped into the clamping groove, which is more labor-saving.

[0012] Optionally, the slot side wall of the card slot is formed with a locking slope, and the inclination direction of the locking slope is consistent with the inclination direction of the guide slope.

[0013] By adopting the above technical scheme, when the shoe sole is used, the elastic flange moves along the locking slope towards the slot bottom wall of the mounting slot after the air cushion is pressed, the elastic flange and the card slot form a mechanical self-locking of "the tighter the pressure is", and the installation stability of the air cushion is further improved.

[0014] Optionally, an unlocking hole is formed in the outer surface of the insole and communicates with the card slot, an unlocking rod is slidably arranged in the unlocking hole, and the end of the unlocking rod close to the air cushion is used to abut against the guide slope.

[0015] By adopting the above technical scheme, the user can press the unlocking rod, the end of the unlocking rod abuts against and presses the guide slope, the elastic flange is compressed, the elastic flange is compressed to the air cushion which can be easily taken out of the mounting slot, and the air cushion is conveniently disassembled.

[0016] Optionally, a reset plate is arranged on the inner wall of the unlocking hole, a reset elastic member is connected between the unlocking rod and the reset plate, and the reset elastic member is used to drive the unlocking rod to move away from the air cushion.

[0017] By adopting the above technical scheme, the reset elastic member drives the unlocking rod to reset, and the user can press the unlocking rod next time.

[0018] Optionally, an elastic sealing member is arranged between the contact surface of the air cushion and the mounting slot.
