[0002] Shoes are necessities in people's daily lives. The wear resistance and weight of the soles of shoes during wearing are very important to the wearer's sports experience. In the existing technology, rubber materials are usually used as wear-resistant materials for soles, and TPU materials are usually used as lightweight materials. TPU has light performance and good shock absorption effect when used as sole materials. Therefore, these two materials are often combined to make soles that have light, comfortable, non-slip and wear-resistant properties.

[0003] The combination of rubber and TPU materials is generally achieved through glue or other adhesives, but the soles made in this way may become detached after long-term use and aging, affecting the durability of the shoes. Therefore, a lightweight sole is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a lightweight sole to solve the problem that the existing lightweight soles made of rubber, TPU materials and glue may come apart after long-term use, thereby affecting the durability of the shoes.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A lightweight sole comprises a rubber layer, a TPU layer and a middle connecting ring belt, the TPU layer is installed on the upper side of the rubber layer, and the middle connecting ring belt is sleeved on the rubber layer and the TPU layer, the rubber layer comprises a lower sole, a lower connecting ring groove is opened at the upper edge of the lower sole, ribs are fixedly connected to the front and rear sides of the upper part of the lower sole, a group of multiple splicing strips are fixedly connected between a group of the ribs, and a group of multiple clips are provided on the front and rear sides of the ribs, the TPU layer comprises an upper sole bonded to the upper end surface of the lower sole, rib grooves are opened on the front and rear sides of the lower part of the upper sole, a group of multiple splicing grooves are opened between a group of the rib grooves, a bayonet is opened on the lower side of the splicing groove, a group of multiple clip grooves are opened on the front and rear sides of the rib groove, an upper connecting ring groove is opened at the lower edge of the upper sole, and the middle connecting ring belt is fixedly connected to the inner side of the upper connecting ring groove and the lower connecting ring groove.

[0007] Preferably, the cross sections of the lower base and the upper base are set to the same size, and the lower base and the upper base are set to the same curvature.

[0008] Preferably, the ribs, splicing strips and buttons are all arranged on the inner side of the lower connecting ring groove, the lower connecting ring groove is connected to the upper connecting ring groove, and a smooth transition is arranged between the inner walls of the lower connecting ring groove and the upper connecting ring groove.

[0009] Preferably, the buttons are all clamped on the inner side of the clamping groove, the ribs are all inserted into the inner side of the rib groove, the splicing strips are all clamped into the inner side of the splicing groove, and the inner width of the clamping port is smaller than the inner diameter of the splicing groove.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A lightweight shoe sole comprises a rubber layer 1, a TPU layer 2 and a center ring belt 3. The TPU layer 2 is mounted on the upper side of the rubber layer 1, and the center ring belt 3 is sleeved between the rubber layer 1 and the TPU layer 2. The rubber layer 1 comprises a lower bottom 11. A lower connecting ring groove 15 is provided at the upper edge of the lower bottom 11. Ribs 12 are fixedly connected to the front and rear sides of the upper part of the lower bottom 11. A group of multiple splicing strips 13 are fixedly connected between a group of ribs 12. A group of multiple snap buttons are provided on the front and rear sides of the ribs 12. 14. The TPU layer 2 includes an upper base 21 bonded to the upper end surface of the lower base 11. Rib grooves 22 are provided on both the front and rear sides of the lower part of the upper base 21. A group of multiple splicing grooves 23 are provided between a group of rib grooves 22. A bayonet 24 is provided on the lower side of the splicing grooves 23. A group of multiple snap grooves 25 are provided on the front and rear sides of the rib grooves 22. An upper connecting ring groove 26 is provided at the lower edge of the upper base 21. The upper connecting ring groove 26 and the inner side of the lower connecting ring groove 15 are fixedly connected with a middle connecting ring belt 3.

[0026] The cross-sections of the lower bottom 11 and the upper bottom 21 are set to the same size, and the lower bottom 11 and the upper bottom 21 are set to the same curvature. Through this setting, the lower bottom 11 can be re-fitted with the upper bottom 21; the ribs 12, the splicing strips 13 and the card buttons 14 are all arranged on the inner side of the lower connecting ring groove 15, and the lower connecting ring groove 15 is connected to the upper connecting ring groove 26. The inner walls of the lower connecting ring groove 15 and the upper connecting ring groove 26 are smoothly transitioned. Through this setting, it is convenient for the middle connecting ring belt 3 to adhere to the lower connecting ring groove 15 and the upper connecting ring groove 26; the card buttons 14 are all clamped on the inner side of the card groove 25, the ribs 12 are all inserted into the inner side of the rib groove 22, and the splicing strips 13 are all clamped in the splicing groove 23. On the inside, this arrangement improves the connection strength between the rubber layer 1 and the TPU layer 2, and the inner width of the bayonet 24 is smaller than the inner diameter of the splicing groove 23. This arrangement enables the splicing strip 13 to pass through the bayonet 24 and enter the splicing groove 23 on the one hand, and does not affect the limiting performance of the splicing groove 23 on the other hand; the middle connecting ring belt 3 is arranged between the rubber layer 1 and the TPU layer 2, and the thickness of the middle connecting ring belt 3 is the same as the depth of the lower connecting ring groove 15 and the upper connecting ring groove 26. The outer curved surface of the middle connecting ring belt 3 and the outer curved surface of the lower bottom 11 and the upper bottom 21 are smoothly transitioned. This arrangement is beautiful while avoiding damage to the middle connecting ring belt 3 due to protrusion.

[0027] Working process: The connection method of the lightweight sole is as follows. Note: Most of the connection between the rubber layer 1 and the TPU layer 2 is achieved through adhesive. On the one hand, the connection between the rubber layer 1 and the TPU layer 2 is achieved through adhesive bonding. On the other hand, the ribs 12, splicing strips 13 and buttons 14 of the rubber layer 1 are inserted into the rib grooves 22, splicing grooves 23 and card slots 25 of the TPU layer 2 (the splicing strip 13 needs to pass through the card slots 24 before it can be inserted into the card slots 25). This can improve the connection strength between the rubber layer 1 and the TPU layer 2. The splicing between the rubber layer 1 and the TPU layer 2 will connect the lower connecting ring groove 15 and the upper connecting ring groove 26 to form a complete ring groove. At this time, adhesive can be applied to the ring groove, and the middle ring belt 3 can be inserted into the ring groove to connect with it. The middle ring belt 3 can further strengthen the connection between the rubber layer 1 and the TPU layer 2 on the one hand, and avoid the glue from coming apart at the splicing edge of the rubber layer 1 and the TPU layer 2 on the other hand, so that the various clip structures of the lightweight sole can cooperate with the adhesive to strengthen the connection strength between the rubber layer 1 and the TPU layer 2.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
