[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] Refer to Figure 1-Figure 3 As shown, the first embodiment of the utility model provides a rapid prototyping structure of a sole and an upper, including a sole 1 and an upper 2. The upper 2 is made of waterproof material or other materials, which is determined according to the performance of the shoe. A positioning portion 3 and a connecting member 4 are provided on the sole 1. The positioning portion 3 includes a plurality of upwardly protruding limit blocks 31 uniformly distributed along the contour of the sole 1 on the edge of the upper end surface of the sole 1.

The upper 2 is provided with limit holes 21 corresponding to the limit blocks 31, and the limit holes 21 are sleeved on the limit blocks 31. The connecting member 4 is used to strengthen the connection between the upper 2 and the sole 1. The positioning portion 3 and the connecting member 4 simplify the connection and molding steps of the upper 2 and the sole 1 in the prior art, thereby accelerating the molding of the shoe.

[0020] For details, refer to Figure 1-Figure 3 As shown, the connecting member 4 includes a baffle 5 that fits the contour of the sole 1. The cross section of the baffle 5 is inverted L-shaped and fits the edge of the sole 1.

The adhesive shoes in the prior art all achieve the connection between the upper 2 and the sole 1 by brushing glue or combining stitching and brushing glue. At the same time, with the advancement of technology, people now have an increasing demand for replaceable soles 1 or replaceable uppers 2, which leads to a decrease in the efficiency of brushing glue, stitching and other methods and a slow speed of shoe molding. Therefore, the utility model uses a positioning part 3 and a connecting member 4, and then adopts a connecting rod 6 and a threaded groove 7 threaded connection method or a clip slot buckle connection method to achieve a reinforced connection between the retaining bar 5 and the sole 1, and also clamps the upper 2 between the sole 1 and the retaining bar 5, so as to prevent the upper 2 from escaping from the limit block 31 and speed up the shoe molding speed.

[0021] Refer to Figure 2 As shown, the stop bar 5 is provided with a limiting groove 13 corresponding to the limiting block 31, and the upper end of the limiting block 31 is inserted into the limiting groove 13, further clamping the upper 2 to prevent the limiting hole 21 of the upper 2 from escaping from the limiting block 31.

[0022] Refer to Figure 2 , Figure 3 As shown, in order to enhance the waterproofness between the upper 2 and the baffle 5, a circle of first adhesive portion 14 is provided on the outer end surface of the upper 2 near the baffle 5, and a second adhesive portion 15 is provided on the upper end surface of the baffle 5. The first adhesive portion 14 and the second adhesive portion 15 are bonded with waterproof cloth 16 to form a triangular waterproof area, which can ensure that rainwater will not penetrate into the shoe cavity from between the upper 2 and the baffle 5, and at the same time form an inclined surface to prevent rainwater from accumulating on it. The waterproof cloth 16 is provided by bonding, which is convenient for replacing the waterproof cloth 16. For example, it can be replaced with cotton strips in winter to increase warmth retention and windproofness; or replaced with reflective strips to ensure that a certain amount of light is provided in the dark.

[0023] Reference Figure 4-Figure 6 As shown, the second embodiment is basically the same as the first embodiment, and the only difference is that: the connecting member 4 includes a plurality of baffles 5 and adjacent baffles 5 are spliced ​​with each other, the cross-section of the baffles 5 is inverted L-shaped and fits with the edge of the sole 1, and the end faces of the plurality of baffles 5 facing the side wall of the sole 1 are provided with rack grooves 8, and a driving member 9 is engaged with the rack grooves 8, and the side wall of the sole 1 is provided with a groove 10 corresponding to the driving member 9 and a threaded section is provided at the end of the groove 10, and the driving member 9 is threadedly connected to the threaded section to limit the rotation of the driving member 9.

[0024] Furthermore, the driving member 9 includes a fixed rod 91 and a moving rod 92 slidably sleeved on the fixed rod 91, the fixed rod 91 is fixedly connected to the groove 10, the moving rod 92 is provided with a transverse sliding groove 93 at a position corresponding to the gear 95 groove, the transverse sliding groove 93 is connected to a gear 95 through a slider 94, and the moving rod 92 is provided with a thread at the end facing the threaded section.

[0025] Specific references such as Figure 4-Figure 6As shown, the connecting member 4 of the second embodiment is different from the connecting member 4 of the first embodiment. The connecting member 4 of the second embodiment includes a plurality of baffles 5 and the adjacent baffles 5 are spliced ​​with each other, so that the upper 2 on a certain baffle 5 can be locally adjusted. The cross-section of the baffle 5 is inverted L-shaped and fits with the edge of the sole 1. The end faces of the plurality of baffles 5 facing the side wall of the sole 1 are provided with rack grooves 8, and a driving member 9 is engaged with the rack grooves 8. The driving member 9 includes a fixed rod 91 and a moving rod 92 slidably sleeved on the fixed rod 91. A groove 10 is provided on the side wall of the sole 1 corresponding to the fixed rod 91, and a threaded section is provided at the bottom end of the groove 10. A transverse slide groove 93 is provided at the position of the moving rod 92 at the outer end of the groove 10 corresponding to the groove of the gear 95. The transverse slide groove 93 is arranged along the length of the moving rod 92, and a gear 95 is connected to the transverse slide groove 93 through a slider 94. The gear 95 Engage with the gear 95 groove. In order to ensure the engagement of gear 95 with the gear 95 groove, abutment plates can be extended at the two end surfaces of the toothed groove to limit gear 95 between the abutment plates. When the shoe upper 2 needs to be disassembled, first check whether the baffle bar 5 and the limit block 31 are threadedly connected. If they are threadedly connected, it is necessary to first disengage the rotating block 121 from the limit block 31. After disengagement, the end of the moving rod 92 is disengaged from the threaded section by rotating the moving rod 92. In the process of disengaging the moving rod 92 from the threaded section, the gear 95 also rotates synchronously, thereby causing the meshing gear 95 groove to move upward, thereby realizing the upward movement of the baffle bar 5. If the upward movement distance is not enough, the moving rod 92 can be continued to be rotated to realize the gear 95 groove to continue to move upward under the meshing action of the gear 95, and then the limiting hole 21 of the shoe upper 2 is disengaged from the limit block 31 to realize the separation of the shoe upper 2 and the sole 1. When the upper 2 needs to be installed, the baffle 5 is reversed and moved downward. After it is moved to a suitable position, the moving rod 92 is moved laterally toward the threaded section, and the moving rod 92 is continued to be rotated to achieve the threaded connection between the moving rod 92 and the threaded section. At the same time, the baffle 5 is continuously pushed downward to further clamp the upper 2 between the baffle 5 and the sole 1 to prevent it from detaching.
