Description

Technical Field

[0001] The utility model relates to the technical field of shoe soles, in particular to a shoe sole with the function of preventing the toe from debonding. Background Art

[0002] The sole is an important component to ensure the quality of a pair of shoes. In the prior art, the soles commonly used for sports shoes are usually wrapped with a double-layer sole. Among them, since the shape of sports shoes is usually pointed at the toe position, the sole and the upper are usually bonded together with glue, and the amount of glue that can be attached to the toe position is relatively small, and when the user wears the shoes and runs, the toe position is subjected to greater force. Therefore, the connection between the sole and the upper is prone to debonding. Once the shoes have the problem of debonding, even if the user glues them with glue later, they are still prone to cracking again. Therefore, users usually scrap the shoes, which will cause unnecessary waste of resources. However, if too much fixation is performed between the sole and the upper, it will easily affect the overall appearance of the shoes and affect the assembly efficiency of the shoes. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a sole with a toe-opening prevention function, which is easy to assemble, can improve the connection stability between the sole and the upper, and does not affect the overall appearance of the shoe.

[0004] The technical solution of the utility model: a sole with the function of preventing toe from debonding, comprising a sole body and a fixing device connected to the sole body, the sole body comprising a toe portion, a sole portion connected to the toe portion and a heel portion connected to the sole portion, the toe portion, the sole portion and the heel portion being integrally formed, the fixing device comprising a first fixing block fixedly connected to the toe portion and a second fixing block fixedly connected to the toe portion, the first fixing block and the second fixing block both having a certain elasticity, when the first fixing block and the second fixing block are in an initial state, the first fixing block and the second fixing block maintain a surface contact state, the first fixing block and the second fixing block are respectively provided with a first glue layer and a second glue layer, the first glue layer and the second glue layer are respectively located on two contact surfaces when the first fixing block and the second fixing block are in contact.

[0005] By adopting the above technical scheme, when the shoes are assembled, the upper is glued to the sole, and the toe part of the upper is fixed between the first fixing block and the second fixing block. Since the first fixing block and the second fixing block are respectively provided with the first glue layer and the second glue layer, and the first fixing block and the second fixing block both have a certain elasticity, therefore, the first fixing block and the second fixing block will not only apply a clamping force to the toe part of the upper, but the first glue layer and the second glue layer will also fix the upper on both sides, thereby further improving the fixing stability of the sole and the upper at the toe position. In addition, the design of this sole structure can reduce the impact on the overall appearance of the shoe and is very convenient to assemble.

[0006] Further configuration of the utility model: a plurality of positioning protrusions are provided on the first fixed block, and a plurality of limiting grooves are provided on the second fixed block. The shapes and sizes of the positioning protrusions and the limiting grooves are adapted to each other. When the first fixed block and the second fixed block are in a surface contact state, the positioning protrusions correspond one by one to the positions of the limiting grooves respectively, and the positioning protrusions are semi-spherical.

[0007] By adopting the above technical scheme, since the first fixed block is provided with a plurality of positioning protrusions, the second fixed block is provided with a plurality of limiting grooves, and the positioning protrusions correspond one by one to the positions of the limiting grooves, therefore, when the sole and the upper are assembled together, the contact area between the upper and the first fixed block and the second fixed block can be increased, and at the same time, the contact area between the first glue layer and the second glue layer and the upper can be increased, thereby improving the connection stability between the sole and the upper and reducing the phenomenon of toe debonding.

[0008] Further configuration of the utility model: a first mounting threaded hole penetrating the first fixing block is provided on the first fixing block, a second mounting threaded hole is provided on the second fixing block, the second mounting threaded hole does not penetrate the second fixing block, fixing bolts are provided on the first mounting threaded hole and the second mounting threaded hole, and the fixing bolts are threadedly connected to the first mounting threaded hole and the second mounting threaded hole respectively.

[0009] By adopting the above technical solution, since the second mounting threaded hole does not pass through the second fixed block, fixing bolts are provided on the first mounting threaded hole and the second mounting threaded hole. Therefore, the upper and the first fixed block and the second fixed block are fixed together by fixing threads, which can further improve the connection stability between the sole and the upper and reduce the phenomenon of toe debonding.

[0010] A further configuration of the utility model is that the fixing bolt is made of rubber material.

[0011] By adopting the above technical solution, since rubber material has the characteristics of soft texture and good wear resistance, the fixing bolts made of rubber material can improve the comfort of the shoes and reduce the impact on the overall appearance of the shoes.

[0012] A further configuration of the utility model is that the positioning protrusion is provided with a plurality of pits evenly distributed on the surface of the positioning protrusion, and the diameter of the pits is less than or equal to 0.1 cm.

[0013] By adopting the above technical solution, since the positioning protrusion is provided with a plurality of pits evenly distributed on the surface of the positioning protrusion, the contact area between the upper and the positioning protrusion can be further increased. In addition, the pits can absorb more glue, so that the connection stability between the sole and the upper is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] When the shoe is assembled, the upper is glued to the sole, and the toe 3 of the upper is fixed between the first fixing block 6 and the second fixing block 7. Since the first fixing block 6 and the second fixing block 7 are respectively provided with the first glue layer 8 and the second glue layer 9, and the first fixing block 6 and the second fixing block 7 have a certain elasticity, the first fixing block 6 and the second fixing block 7 will not only apply a clamping force to the toe 3 of the upper, but the first glue layer 8 and the second glue layer 9 will also fix the upper on both sides, thereby further improving the fixing stability of the sole and the upper at the toe position. In addition, the design of this sole structure can reduce the impact on the overall appearance of the shoe and is very convenient to assemble.

[0020] The first fixed block 6 is provided with a plurality of positioning protrusions 10, and the second fixed block 7 is provided with a plurality of limiting grooves 11. The positioning protrusions 10 and the limiting grooves 11 are adapted in shape and size. When the first fixed block 6 and the second fixed block 7 are in a surface contact state, the positioning protrusions 10 correspond to the positions of the limiting grooves 11 one by one, and the positioning protrusions 10 are semi-spherical.

[0021] Since the first fixing block 6 is provided with a plurality of positioning protrusions 10, the second fixing block 7 is provided with a plurality of limiting grooves 11, and the positioning protrusions 10 correspond one-to-one to the positions of the limiting grooves 11, when the sole and the upper are assembled together, the contact area between the upper and the first fixing block 6 and the second fixing block 7 can be increased, and at the same time, the contact area between the first glue layer 8 and the second glue layer 9 and the upper can be increased, thereby improving the connection stability between the sole and the upper and reducing the phenomenon of toe debonding.

[0022] The first fixing block 6 is provided with a first mounting threaded hole 12 that penetrates the first fixing block 6, the second fixing block 7 is provided with a second mounting threaded hole 13, the second mounting threaded hole 13 does not penetrate the second fixing block 7, the first mounting threaded hole 12 and the second mounting threaded hole 13 are provided with fixing bolts 14, and the fixing bolts 14 are threadedly connected to the first mounting threaded hole 12 and the second mounting threaded hole 13 respectively.

[0023] Since the second mounting threaded hole 13 does not pass through the second fixing block 7, fixing bolts 14 are provided on the first mounting threaded hole 12 and the second mounting threaded hole 13. Therefore, the upper and the first fixing block 6 and the second fixing block 7 are fixed together by fixing threads, which can further improve the connection stability between the sole and the upper and reduce the phenomenon of the toe coming apart.

[0024] The fixing bolt 14 is made of rubber.
