[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5This utility model provides a technical solution: a breathable and drainable perforated shoe with a protective sponge structure, including a height-increasing sole 1, a supporting sole 2, a protective edge 3, an upper body 4, a waterproof groove 5, an anti-slip strip 6, a water-guiding edge 7, a ventilation hole 8, a limiting sponge 9, a limiting groove 10, a protective sponge body 11, a positioning block 12, a connecting shaft 13, a connecting strap 14, a connecting hole 15, a rubber insole 16, a wear-resistant block 17, and a water-guiding groove 18.
[0029] Specific examples Figure 1 , Figure 2 and Figure 4 As shown, during the production of the clogs, anti-slip strips 6 are arranged at equal intervals on the bottom of the shoe sole 1, so that the anti-slip strips 6 are bonded to the bottom of the shoe sole 1. The upper surface of the shoe sole 1 has a sloping structure. After the shoe sole 1 is placed horizontally, the waterproof groove 5 is parallel to the ground. Hold the support base 2, apply shoe-specific glue to the bottom end of the support base 2 and the top end of the shoe sole 1, align the edge of the support base 2 with the edge of the shoe sole 1, and press the support base 2 so that the lower side of the support base 2 and the upper side of the shoe sole 1 are bonded together by the glue.
[0030] Then, apply shoe glue to the upper side of the support base 2, align the edge of the protective edge 3 with the edge of the support base 2, and press the protective edge 3 so that the bottom end of the protective edge 3 is bonded to the upper edge of the support base 2, thus forming the general shape of the shoe body. Similarly, after applying shoe glue to the bottom end of the rubber insole 16, press the rubber insole 16 onto the upper side of the support base 2, ensuring that the support base 2 and the rubber insole 16 are tightly connected after the glue dries. At this time, the rubber insole 16 is bonded to the upper end of the support base 2. The upper side of the rubber insole 16 is provided with evenly distributed abrasion-resistant blocks 17. When the user wears the Crocs, the sole of the foot comes into contact with the abrasion-resistant blocks 17 on the rubber insole 16, increasing the contact between the anti-slip strip 6 on the lower side of the sole 1 and the ground, which helps to improve the abrasion resistance and anti-slip properties of the Crocs.
[0031] Specific examples Figure 1 and Figure 2 As shown, a water-guiding edge 7 is provided at the upper left end of the protective edge 3. The right side of the water-guiding edge 7 is attached to the left side of the shoe upper body 4. The water-guiding edge 7 has water-guiding grooves 18 arranged at equal intervals inside, and the water-guiding grooves 18 are set in an inclined structure. When the user wears the Crocs and walks on a wet road, water splashes onto the water-guiding edge 7 due to inertia. When there is enough water, the water will gather at the right end of the water-guiding grooves 18 and be guided by the inclined water-guiding grooves 18 to drain the water accumulated on the water-guiding edge 7.
[0032] Meanwhile, the interior of the shoe upper body 4 has evenly distributed ventilation holes 8. When the user wears the Crocs, the interior of the Crocs is connected to the outside through the ventilation holes 8, which facilitates the ventilation and drainage function of the Crocs.
[0033] Specific examples Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the connecting strap 14 is located on the outside of the protective edge 3. The connecting strap 14 has a "C" shaped structure, and the front and rear ends of the connecting strap 14 are symmetrical about the center line of the protective edge 3. Both the front and rear ends of the connecting strap 14 are provided with connecting holes 15. Two connecting shafts 13 are selected, and the connecting shafts 13 are aligned with the connecting holes 15 on the front and rear sides of the connecting strap 14 and pressed, so that the connecting shafts 13 pass through the connecting holes 15 on the front and rear sides of the connecting strap 14 and connect with the protective edge 3. When wearing the clogs, the connecting strap 14 can be moved, and the inner side of the connecting strap 14 rubs against the outer side of the protective edge 3, so that the inner wall of the connecting hole 15 on the front and rear sides of the connecting strap 14 slides against the outer wall of the protective edge 3. At the same time, the inner wall of the connecting strap 14 and the front and rear sides of the protective edge 3 generate sliding friction.
[0034] Next, the limiting sponge 9 and the positioning block 12 are bonded together, forming a U-shaped structure in the longitudinal section. This structure is then fitted onto the right side of the upper body 4, so that the upper right side of the upper body 4 is attached to the lower side of the limiting sponge 9, and the lower right side of the upper body 4 is attached to the upper side of the positioning block 12. A protective sponge body 11 is positioned on the left side of the positioning block 12, with evenly spaced protective sponge bodies 11 forming a T-shaped structure. The protective sponge body 11 is composed of circular plate-like and columnar structures. After the positioning block 12 is attached to the upper body 4, the protective sponge body 11 is moved. The columnar structure of the protective sponge body 11 passes through the limiting groove 10 opened inside the limiting sponge 9. The plate-like structure of the protective sponge body 11 passes completely through the limiting groove 10 and is attached to the limiting sponge 9. When the user wears the clogs with the limiting sponge 9 and positioning block 12 installed, the positioning block 12 plays a cushioning role, avoiding bleeding of the user's instep due to friction. This facilitates the sponge protection function of the breathable and drainage clogs. This is the usage method of this type of breathable and drainage clogs with a protective sponge structure.
