Description

Technical Field

[0001] This utility model belongs to the technical field of footwear accessories, specifically relating to an insole with cross-stitch needle holes. Background Technology

[0002] Cross-stitch needle-hole insoles are a type of insole product that combines traditional cross-stitch with modern techniques. They make the embroidery process easier and more accurate by pre-creating a needle-hole mesh on a regular insole. These insoles typically use molds or machinery to create a mesh that runs the entire length of the insole on a blank sheet. This mesh is arranged in the same way as cross-stitch fabric, reducing friction when threading the needle and ensuring accurate placement.

[0003] Existing cross-stitch needlehole insoles are mostly solid colors or fixed prints, with weak decorative properties and no possibility of personalized modification. If they are embroidered by hand, it is easy to damage the insole structure and also cause the needle holes to become larger. In addition, most cross-stitch needlehole insoles are not very comfortable. Therefore, we propose an insole with cross-stitch needle holes. Utility Model Content

[0004] The purpose of this invention is to provide an insole with cross-stitch needle holes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insole with cross-stitch needle holes, comprising an insole body, wherein multiple sets of needle holes are uniformly opened through the surface of the insole body, the inner wall of the needle holes is covered with a nano-silicone layer, a shape memory alloy is embedded in the inside of the needle holes, the shape memory alloy is composed of nickel-titanium alloy material, and a reinforcing edge is wrapped and fixed on the outer edge of the insole body.

[0006] Preferably, the surface of the insole body is provided with a microfiber cloth layer.

[0007] Preferably, the embroidered layer of the insole body is provided with a high-density sponge layer.

[0008] Preferably, the support layer of the insole body is provided with a skeleton layer, and the skeleton layer is a thermoplastic polyurethane hollow skeleton.

[0009] Preferably, the cushioning layer of the insole body is provided with a silicone airbag layer.

[0010] Preferably, the bottom layer of the insole body is provided with anti-slip rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The multiple needle holes facilitate manual embroidery on the insoles. The inner wall of the needle holes is covered with a nano silicone layer to prevent the holes from enlarging due to repeated punctures.

[0013] 2. The ultra-fine fiber fabric layer enhances the antibacterial and deodorizing effects of the insole. The shape memory alloy embedded in the needle holes of the embroidery layer can expand the pore size according to the temperature of the insole, thereby improving breathability and increasing user comfort. The silicone airbag layer enhances the cushioning and shock absorption performance of the insole. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 This utility model provides a technical solution: an insole with cross-stitch needle holes, including an insole body 1, with multiple sets of needle holes 2 evenly opened through the surface of the insole body 1, the inner wall of the needle holes 2 being covered with a nano silicone layer 3, and a memory alloy 301 embedded in the inside of the needle holes 2. The memory alloy 301 is composed of nickel-titanium alloy material, and a reinforcing edge 4 is wrapped and fixed on the outer edge of the insole body 1.

[0019] Specifically, the surface of the insole body 1 is provided with a microfiber cloth layer 101, the embroidery layer of the insole body 1 is provided with a high-density sponge layer 102, the support layer of the insole body 1 is provided with a skeleton layer 103, the skeleton layer 103 is made of thermoplastic polyurethane hollow skeleton, the cushioning layer of the insole body 1 is provided with a silicone airbag layer 104, and the bottom layer of the insole body 1 is provided with anti-slip rubber 105.

[0020] In this embodiment, by covering the inner wall of the needle hole 2 with a nano-silicone layer 3, the enlargement of the hole 2 caused by repeated punctures can be prevented, thus avoiding its impact on subsequent use. The ultra-fine fiber cloth layer 101 increases the antibacterial and deodorizing effect of the insole body 1. The high-density sponge layer 102 facilitates the pre-pressing of the cross-stitch needle hole 2 grid and is compatible with multiple strands of embroidery thread. The thermoplastic polyurethane hollow skeleton layer 103 corresponds to the foot pressure zone, improving comfort. By embedding a shape memory alloy 301 in the needle hole 2 of the embroidery layer, the diameter of the needle hole 2 can be enlarged according to the temperature increase of the insole body 1, thereby improving breathability and increasing user comfort. The reinforcing edge 4 further improves the structural strength of the insole body 1. The silicone airbag layer 104 increases the cushioning and shock absorption performance of the insole body 1. The anti-slip rubber 105 increases the friction of the bottom contact of the insole body 1.

[0021] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
