[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the present application provides a first embodiment of a waterproof shoe, including a first sole 1, a second sole 2 and an upper 3. The side edge of the first sole 1 is provided with a special-shaped groove 4 along the shape of the first sole 1. The upper end portion of the special-shaped groove 4 is arc-shaped and forms an arc-shaped portion 5. The inner end surface of the bottom of the upper 3 is connected to the arc-shaped portion 5 through a first connecting member 6. The first connecting member 6 includes a plurality of oblique holes 61 obliquely provided along the edge of the arc-shaped portion 5 and a fixed horizontal bar 62 is provided at the upper end of the oblique hole 61. A connecting ring 31 is provided on the inner end surface of the bottom of the upper 3. The connecting ring 31 is sewn to the bottom of the upper 3 but does not penetrate the upper 3 for sewing, thereby ensuring that the upper 3 is complete and has no holes 19 to reduce the probability of rainwater seeping into the shoe cavity. A connecting rope 9 is connected between the connecting ring 31 and the fixed horizontal bar 62, and the stitching is reinforced to avoid loosening. The outer end surface of the bottom of the upper 3 is connected to the reinforced waterproof member 8 through the second connecting member 7. The second connecting member 7 includes a plurality of waterproof protrusions 71 provided on the outer end surface of the upper 3. The waterproof protrusions 71 are provided with a first transverse through hole 72 and a second transverse through hole 73, and the first transverse through hole 72 and the second transverse through hole 73 are connected to each other. The inner end surface of the reinforced waterproof member 8 is provided with an annular groove 74 at a position corresponding to the waterproof protrusion 71. An insert block 75 is provided in the annular groove 74. The insert block 75 is L-shaped and the insert block 75 is provided corresponding to the second transverse through hole 73. There is a through groove 76 for the water stop strip 77 to penetrate. The reinforced waterproof part 8 aligns the annular groove 74 with the waterproof protrusion 71, and the water stop strip 77 is inserted into the plug block 75 and the second transverse through hole 73, along the bottom of the upper 3. The water stop strip 77 penetrates each plug block 75 and the second transverse through hole 73 like a needle and thread, connecting the upper 3 with the reinforced waterproof part 8 while enhancing the waterproofness between the reinforced waterproof part 8 and the upper 3. After all the water stop strips 77 are penetrated and fixedly connected from head to tail, the head and tail of the reinforced waterproof part 8 are also fixedly connected. The reinforced waterproof part 8 is a waterproof metal strip 10, and other waterproof materials can also be used. The present application preferably selects the waterproof metal strip 10 to increase the overall appearance of the shoe while being waterproof. The waterproof metal strip 10 is generally arc-shaped, with a Y-shaped end 11 at the head and a C-shaped end 12 at the tail. The C-shaped end 12 fits the internal shape of the special-shaped groove 4. In order to ensure that the second sole 2 is tightly connected with the upper and the first sole 1, the waterproof metal strip 10 is provided with multiple circular holes at other positions except the Y-shaped end 11, thereby ensuring that the injection molding liquid of the second sole 2 can penetrate and fit with the upper and the first sole 1. The second sole 2 is connected with the upper and the first sole 1 by integrated injection molding, and the second sole 2 is provided with a special-shaped block 17 corresponding to the special-shaped groove 4. The upper end surface of the special-shaped block 17 is arc-shaped and forms a retaining wall 18. The upper 3 is connected with the first sole 1 to form a shoe cavity, and the shoe last is placed in the shoe cavity. The first sole 1 with the upper 3 and the shoe last is placed in the mold of the second sole 2, and the injection molding liquid is injected into the second mold to form the second sole 2. The mold is cooled and demolded to form a complete shoe body, and then the Y-shaped end 11 is adjusted to fit the side edge of the shoe.

[0023] The upper 3 includes a waterproof upper 32, which is provided with an ankle socket 33 and an instep opening 34, a tongue is arranged at the instep opening 34, a waterproof Velcro 35 is arranged at the instep opening 34, and a zipper 36 is arranged at the ankle socket 33, which is used to connect the waterproof shoe cover. The waterproof Velcro 35 and the waterproof shoe cover can reduce the infiltration of rainwater from the instep opening 34 and the ankle socket 33.

[0024] The second embodiment is basically the same as the above-mentioned embodiment 1, and the only difference is that: the reinforced waterproof part 8 includes a first metal strip 13 and a second metal strip 14, the first metal strip 13 is arc-shaped as a whole, with a Y-shaped end 11 at the head and a C-shaped end 12 at the tail, the C-shaped end 12 is in conformity with the inner shape of the special-shaped groove 4 and the C-shaped end 12 is provided with a circular hole, an extension protrusion 15 is provided on the outer end face of the bottom of the first metal strip 13, a groove 16 is provided on the inner end face of the first metal strip 13, the second metal strip 14 is fixed in the groove 16, and the annular groove 74 is provided on the second metal strip 14.

[0025] On the basis of the above embodiment, the second sole 2 is made of a strip of soft waterproof elastic material and is fixedly connected at the head and tail by fixing parts. The second sole 2 is provided with a special-shaped block 17 corresponding to the special-shaped groove 4. The upper end surface of the special-shaped block 17 is arc-shaped and forms a retaining wall 18. The retaining wall 18 is provided with a hole 19 corresponding to the extended protrusion 15. A support 20 is provided in the hole 19. The retaining wall 18 is fitted with the waterproof metal strip 10. The inner end surface of the second sole 2 and the contact end surface of the first sole 1 and the waterproof metal strip 10 are bonded to each other by waterproof glue or hot-melt adhesive sheet.

[0026] On the basis of the above embodiment, the support member 20 is a rod with a certain hardness connected to the hole 19 to support and tighten the arc portion 5.

[0027] like Figure 3As shown, the above improvement is specifically as follows: the reinforced waterproof member 8 includes a first metal strip 13 and a second metal strip 14, the first metal strip 13 is arc-shaped as a whole, a Y-shaped end 11 is provided at the head, and a C-shaped end 12 is provided at the tail, the C-shaped end 12 is in a shape that fits the inner shape of the special-shaped groove 4 and the C-shaped end 12 is provided with a round hole, an extended protrusion 15 is provided on the outer end surface of the bottom of the first metal strip 13, a groove 16 is provided on the inner end surface of the first metal strip 13, the second metal strip 14 is fixed in the groove 16 by welding or bonding, an annular groove 74 is provided on the second metal strip 14, the second sole 2 is made of a soft material waterproof elastic material strip, and the second The sole 2 is made of a soft waterproof elastic material strip. The second sole 2 is enclosed around the first sole 1, the upper 3, and the reinforced waterproof part 8, and tightly wraps the first sole 1, the upper 3, and the reinforced waterproof part 8 to prevent rainwater from seeping in. The second sole 2 is provided with a special-shaped block 17 corresponding to the special-shaped groove 4. The upper end of the special-shaped block 17 is arc-shaped and forms a retaining wall 18. The retaining wall 18 is provided with a hole 19 corresponding to the extended protrusion 15. A support member 20 is provided in the hole 19. The support member 20 is a rod with a certain hardness connected to the hole 19. The rod can resist the arc portion 5 to further increase the support force of the side of the sole. Figure 6 As shown, the inner end surface of the second sole 2 and the contact surface between the first sole 1 and the waterproof metal strip 10 are bonded to each other through waterproof glue or hot-melt adhesive sheet, which further improves the tightness and avoids the risk of rainwater penetration.
