Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and in particular to an EVA shoe sole with cushioning function. Background Technology

[0002] EVA soles refer to soles made primarily of ethylene-vinyl acetate copolymer. EVA is a lightweight, soft, and highly elastic foam plastic, widely used in athletic shoes, casual shoes, and other footwear requiring cushioning and comfort due to its excellent properties.

[0003] Existing EVA soles have cushioning structures that are integrally molded or fixedly connected to the sole body, making them difficult to replace when worn or broken, which can easily affect wearing comfort. Utility Model Content

[0004] The purpose of this invention is to provide an EVA shoe sole with cushioning function in order to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides an EVA shoe sole with cushioning function, the structure of which includes an EVA midsole;

[0007] A cushioned outsole is provided on the bottom surface of the EVA insole.

[0008] The cushioning outsole has an anti-slip zone at the front of the sole, and an isolation strip extends from the anti-slip zone toward the heel of the cushioning outsole. Several cushioning components are provided at equal intervals on the outer side of the isolation strip.

[0009] The cushioning assembly includes an assembly groove located within the cushioning outsole, with the opening of the assembly groove facing downwards. An anti-slip protrusion is sealed and embedded at the bottom opening of the assembly groove. An arched air cushion is located at the top of the anti-slip protrusion within the assembly groove. An elastic locking block extends from the top of the arched air cushion. A locking groove that engages with the elastic locking block is provided within the interlayer of the cushioning outsole. A deformation groove is provided near the inner opening of the arched air cushion on the elastic locking block. A tension strip is provided at the bottom of the deformation groove, located at the inner opening of the arched air cushion. At least one air cavity is provided within the arched air cushion. A tool insertion port communicating with the inner opening of the arched air cushion is provided in the middle of the anti-slip protrusion.

[0010] In the above technical solution, the EVA sole adopts an independent and modular cushioning component design. The appropriate number of cushioning components can be assembled according to the wearer's needs. When the cushioning component is damaged or broken, it can be quickly disassembled and replaced with a special removal lever to prevent affecting the comfort of wearing. The disassembly method involves inserting the hook at the top of the removal lever through the tool inlet, hooking it with the pull bar, and then pulling it downwards with a little force. This causes the pull bar to deform the deformation groove, and at the same time, it causes the elastic block to deform and retract. Under the action of the pulling force, the elastic block elastically disengages from the groove, and the arched air cushion can be removed. The operation is simple.

[0011] In one embodiment, the anti-slip zone is composed of a plurality of grooves, which are connected in a mutually enclosing or interlacing manner. This technical solution improves the anti-slip effect through the groove structure.

[0012] In one embodiment, the upper part of the elastic block has a mushroom-shaped structure and the lower part has a frustum-shaped structure, which makes the structure convenient for locking and use.

[0013] In one embodiment, the deformation groove is a conical structure, and the apex of the conical structure is located inside the upper part of the elastic block. This technical solution makes it easy for the elastic block to disengage from the groove after compression deformation.

[0014] In one embodiment, the anti-slip protrusion has anti-slip texture on its bottom surface, and its bottom surface is lower than the bottom surface of the cushioning outsole. This technical solution can perform cushioning positioning, and the anti-slip protrusion being lower than the bottom edge of the cushioning outsole allows the anti-slip protrusion to contact the ground.

[0015] In one embodiment, the anti-slip protrusion has an elliptical cross-section, and the outer ring of the cross-section is provided with a sealing ring that contacts the inner wall of the assembly groove. This technical solution can effectively prevent water from entering through the sealing ring.

[0016] In one embodiment, a removal rod is also included, the top of which is provided with an insertion port for a tool and a hook for the pull bar hook. This technical solution facilitates disassembly and assembly.

[0017] In addition, the tension strip is U-shaped to facilitate pulling.

[0018] The advantages or beneficial effects of the above technical solutions include at least the following:

[0019] This utility model discloses an EVA shoe sole with cushioning function. The EVA shoe sole adopts an independent and modular cushioning component design. The appropriate number of cushioning components can be assembled according to the wearer's needs. When the cushioning component is damaged or broken, it can be quickly disassembled and replaced with a special removal lever to prevent it from affecting the comfort of wearing.

[0033] The cushioning outsole has an anti-slip zone at the front of the sole, and an isolation strip extends from the anti-slip zone toward the heel of the cushioning outsole. Several cushioning components are provided at equal intervals on the outer side of the isolation strip.

[0034] The cushioning assembly includes an assembly groove located within the cushioning outsole, with the opening of the assembly groove facing downwards. An anti-slip protrusion is sealed and embedded at the bottom opening of the assembly groove. An arched air cushion is located at the top of the anti-slip protrusion within the assembly groove. An elastic locking block extends from the top of the arched air cushion. A locking groove that engages with the elastic locking block is provided within the interlayer of the cushioning outsole. A deformation groove is provided near the inner opening of the arched air cushion on the elastic locking block. A tension strip is provided at the bottom of the deformation groove, located at the inner opening of the arched air cushion. At least one air cavity is provided within the arched air cushion. A tool insertion port communicating with the inner opening of the arched air cushion is provided in the middle of the anti-slip protrusion.

[0035] In the above technical solution, the EVA sole adopts an independent and modular cushioning component design. The appropriate number of cushioning components can be assembled according to the wearer's needs. When the cushioning component is damaged or broken, it can be quickly disassembled and replaced with a special removal lever to prevent affecting the comfort of wearing. The disassembly method involves inserting the hook at the top of the removal lever through the tool inlet, hooking it with the pull bar, and then pulling it downwards with a little force. This causes the pull bar to deform the deformation groove, and at the same time, it causes the elastic block to deform and retract. Under the action of the pulling force, the elastic block elastically disengages from the groove, and the arched air cushion can be removed. The operation is simple.

[0036] In one embodiment, the anti-slip area 21 is composed of a plurality of grooves, which are connected in a mutually enclosing or interlacing manner. This technical solution improves the anti-slip effect through the groove structure.

[0039] In one embodiment, the bottom surface of the anti-slip protrusion 232 has anti-slip texture, and its bottom surface is lower than the bottom surface of the buffer outsole 2. This technical solution can perform buffer positioning, and the anti-slip protrusion 232 being lower than the bottom edge of the buffer outsole 2 allows the anti-slip protrusion 232 to contact the ground.

[0040] In one embodiment, the anti-slip protrusion 232 has an elliptical cross-section, and the outer ring of the cross-section is provided with a sealing ring that contacts the inner wall of the assembly groove 231.
