Description

Technical Field

[0001] This utility model relates to the field of footwear, and in particular to a shoe insole and sole that are easy to assemble and disassemble. Background Technology

[0002] Carbon fiber plates embedded in the soles of athletic shoes, guided by the bending action of the carbon fiber plates, can provide athletes with a certain boost and speed, making them very popular among modern people. Currently, most carbon fiber plate running shoes and carbon fiber plate trail running shoes on the market have non-removable carbon fiber plates, which are either placed between two midsoles or sandwiched between the outsole and the midsole, resulting in relatively limited usage scenarios.

[0003] Referring to Chinese Utility Model Patent CN220157689U, a high-elasticity, anti-torsion, and speed-enhancing functional insole is disclosed, comprising a main body. A third groove is formed on the lower surface of the main body, and a support plate is held within the third groove. A second strip-shaped protrusion is provided on the side of the third groove near the toe, and a second circular protrusion is provided on the side of the third groove near the heel. The second strip-shaped protrusion is positioned opposite to the strip-shaped notch, and the second circular protrusion is positioned opposite to the arc-shaped notch, so that the support plate is held within the third groove. However, this insole still has shortcomings. The arc-shaped notch faces backward, and during use, the support plate is typically bent repeatedly along the longitudinal direction. The second circular protrusion easily detaches from the arc-shaped notch, causing the support plate to fall off. The insole is not securely attached to the support plate, resulting in a poor wearing experience for the user. Summary of the Invention

[0004] This invention provides an insole and sole that are easy to assemble and disassemble, in order to solve the problems of the aforementioned insole having weak or unstable fastening.

[0005] The present invention adopts the following technical solution: An easily detachable insole includes an insole body and a support plate. The bottom surface of the insole body has a receiving groove that extends from the ball of the foot to the heel. The support plate is fitted into the receiving groove. The front end of the support plate has a guide groove and a circular hole connected to the rear end of the guide groove. The diameter of the circular hole is larger than the width of the guide groove opening. The bottom of the front end of the receiving groove has a positioning post with a rectangular cross-section. The width of the positioning post matches the width of the guide groove opening, and the length of the positioning post matches the diameter of the circular hole. The end of the positioning post away from the insole body is connected to a positioning cap, the width of which is larger than the diameter of the circular hole. The side edge of the rear end of the support plate has a latch, and the bottom of the rear end of the receiving groove has a locking post that matches the latch. The lower end of the locking post is connected to a locking cap, the outer diameter of which is larger than the diameter of the latch.

[0006] Furthermore, the ratio of the groove width of the guide groove to the diameter of the circular hole is 1:1.1 to 1.3, preferably the ratio of the groove width of the guide groove to the diameter of the circular hole is 1:1.1.

[0007] Furthermore, the insole body mentioned above is a TPU insole.

[0008] Furthermore, the aforementioned support plate is a carbon fiber plate.

[0009] A shoe sole includes a sole body, on which the aforementioned easily removable insole is stacked.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The positioning column of this application adopts a rectangular cross-section design. Its linear fit with the guide groove can restrict the rotation of the support plate around the positioning column, further ensuring the positional accuracy of the support plate in the receiving groove and avoiding the support effect caused by the offset of the support plate. Users can disassemble and assemble the support plate without the aid of tools, and can achieve accurate positioning without repeated adjustments. It combines convenience and accuracy, and is simple and convenient to operate.

[0011] 2. In this patent, the support plate is detachable through a "guided positioning + snap-lock" structure: users can freely choose whether to install the support plate according to actual needs: install it during exercise to boost speed with the support of the carbon fiber plate; remove it for daily walking to retain only the comfort of the TPU insole and avoid the rigidity of the carbon plate from restricting daily wear; at the same time, the detachable design also facilitates the individual maintenance and replacement of the support plate or the insole itself, reducing user costs and significantly improving the product's adaptability and economy.

[0012] 3. The front end of the support plate of this application is provided with a guide groove and a round hole. The diameter of the round hole is larger than the width of the guide groove. A rectangular section positioning post and a positioning cap are provided at the front end of the groove. The width of the positioning post is adapted to the opening of the guide groove to ensure accurate guidance during installation. The length of the positioning post is adapted to the diameter of the round hole to ensure tight fit after assembly. The width of the positioning cap is larger than the diameter of the round hole to axially restrict the support plate from coming off. The support plate has a latch on the rear side edge, and a locking post and a locking cap are set at the rear end of the receiving groove. The outer diameter of the locking cap is larger than the diameter of the latch. After assembly, the latch and the locking post are tightly engaged, and the locking cap restricts the lateral loosening of the support plate from the radial direction. The dual structure works together to effectively resist the displacement force caused by repeated longitudinal bending of the support plate, ensuring that the support plate will not fall off or loosen during long-term use, and significantly improving the stability of wearing.

[0013] 4. This application does not require significant modifications to the existing sole body. It can integrate the "stability support function" into ordinary soles through "stacked" method, quickly upgrading sole performance. It is applicable to professional sports scenarios such as running shoes and trail running shoes, and can also be extended to everyday scenarios such as casual shoes and hiking shoes. It provides a modular solution for "stability support" for different types of footwear products, enhancing the industrial application value of the patented technology. Attached Figure Description
