[0020] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0021] like Figures 1 to 3As shown, a replaceable insole 3 structure for slippers includes a sole 1 and an insole 3. The top surface of the sole 1 is provided with an assembly groove 10. A plurality of clamping strips 11 are provided in the assembly groove 10. The clamping strips 11 are extended along the width direction of the sole 1. The tops of the clamping strips 11 are laterally protruded in both sides and form limiting clamps. Each clamping strip 11 is arranged at intervals along the length direction of the sole 1. A clamping groove 12 is formed between two adjacent clamping strips 11. The insole 3 is movably installed in the assembly groove 10. The bottom of the insole 3 is provided with a plurality of inverted strips 31 arranged at intervals along the length direction of the insole 3. Each inverted strip 31 is respectively plugged into a corresponding clamping groove 12, and the limiting clamps of each clamping strip 11 clamp and act on the corresponding inverted strip 31. The length of each inverted strip 31 matches the length of its corresponding clamping groove 12, and the two ends of the inverted strip 31 are respectively limitedly matched with the ends of the corresponding clamping groove 12. The bottom of the inverted strip 31 is respectively protruded in both directions and forms an inverted portion. The cross-sectional shape of the inverted strip 31 matches the cross-sectional shape of the clamping groove 12. The width of the inverted portion is greater than the slot width of the clamping groove 12. When the inverted strip 31 is inserted into the clamping groove 12, the limiting clamps on both sides of the clamping groove 12 are respectively limited and matched with the inverted portion. The edges of the limiting clamps and the inverted portion are respectively formed with rounded corners. The cross-sectional shapes of the clamping strip 11 and the inverted strip 31 are the same in size, and the two are inverted with each other. The distribution intervals between each clamping strip 11 are equal to the distribution intervals between each inverted strip 31. When the insole 3 is assembled in the assembly groove 10, the top of each clamping strip 11 is respectively in contact with the bottom surface of the insole 3, and the bottom of each inverted strip 31 is respectively in contact with the bottom of the corresponding clamping groove 12.

[0022] The utility model provides a replaceable insole structure for slippers, wherein the insole 3 is assembled by an insole clamping structure composed of a plurality of clamping strips 11. When a user wears the slippers with the insole structure and walks, the clamping strips 11 have a tendency to move closer to each other due to the bending of the sole, and can further clamp the corresponding inverted strips 31 to improve the assembly stability of the insole 3 and reduce the risk of the insole 3 being separated from the sole due to movement; the clamping structure composed of the clamping strips 11 and the inverted strips 31 with the same structure, and the limiting cooperation between the limiting clamps and the inverted buckle parts, can further improve the plug-in stability of the inverted strips 31, reduce the probability of the inverted strips 31 being accidentally separated, and make the insole have a better supporting effect, thereby improving the wearing feel of the slipper product.

[0023] Specifically, the protrusion height of the clamping strip 11 and the inverted insert strip 31 is 12 mm; and the distribution interval between each clamping strip 11 and each inverted insert strip 31 is 8 mm.

[0024] Specifically, the outer surfaces of the clamping strip 11 and the inverted strip 31 are provided with a rough surface structure. The rough surface formed on the surface of the clamping strip 11 and the inverted strip 31 can improve the assembly friction between the two, further improve the stability of the insole structure, and in addition, when the sole 1 and the insole 3 are bent synchronously, the "squeaking" noise caused by the surface friction between the clamping strip 11 and the inverted strip 31 can be avoided, further improving the use experience of the product.

[0025] Specifically, a limiting concave shoulder 13 is formed at the notch of the assembly groove 10; an upper concave shoulder 32 is formed at the edge of the bottom surface of the insole 3, and the upper concave shoulder 32 matches the limiting concave shoulder 13. When the insole 3 is assembled in the assembly groove 10, the upper concave shoulder 32 is exactly matched with the limiting concave shoulder 13, and the edge of the insole 3 is flush with the edge of the sole 1. The positioning requirements of the insole 1 are ensured, and the assembly connection between the insole 3 and the sole 1 is improved, so that the appearance of the slipper product composed of the two is smoother and more uniform.

[0026] Specifically, different insoles 3 are provided with arch support parts of different sizes, massage structures of different specifications or cushioning structures of different specifications on the surface, so that users can choose to use them together. Different soles 1 are provided with anti-skid surface structures 19 of different specifications on the bottom surface; different soles 1 are equipped with different uppers 2. The combination of insoles 3 and soles 1 that can be replaced with each other can form slipper products with more colors and functions, further improving the practicality and use experience of slipper products.

[0027] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
