Description

Technical Field

[0001] The utility model belongs to the technical field of shoe heels, and in particular relates to a shoe heel structure made of a TPU material with three-dimensional air permeability function. Background Art

[0002] TPU material heel refers to the heel part of the shoe that uses thermoplastic polyurethane elastomer rubber, which is a mature environmentally friendly material with excellent wear resistance, tear resistance, flexion strength, tensile strength and high tension. It has a wide hardness range, good elasticity and high transparency. It not only provides good support and fixation, but also increases the beauty and comfort of the shoes.

[0003] The heels of shoes currently on the market have the following problems when used:

[0004] 1. When in actual use, the heels of traditional shoes usually do not have a breathable structure, which will cause the feet to feel stuffy after long-term wear, so their breathability is relatively weak when in use;

[0005] 2. In actual use, most shoe heels often collapse due to their own weight after being worn for a long time, so their supporting effect is not strong during use. Summary of the invention

[0006] The utility model aims to provide a TPU material shoe heel structure with three-dimensional breathable function to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a three-dimensional breathable TPU material heel structure, comprising a heel, a reinforcing plate embedded inside the heel, air holes provided at the bottom of the heel, a waterproof breathable membrane embedded inside the air holes, an embedding groove provided at the bottom of the heel, the embedding grooves being provided in two groups, and anti-slip strips embedded inside the embedding grooves.

[0008] Preferably, a reinforcement ring is provided on the outside of the heel, an upper ring body is provided on the top of the reinforcement ring, and a lower ring body is provided on the bottom of the reinforcement ring.

[0009] Preferably, a slot is provided inside the heel, a reinforcing plate is embedded inside the slot, and the bottom of the reinforcing plate is connected to the vertical plate.

[0010] Preferably, the interior of the vertical plate is inlaid with a hexagon socket bolt, the exterior of the heel is provided with a threaded hole, and the hexagon socket bolt is threadedly connected to the threaded hole.

[0011] Preferably, a circular groove is provided on the outside of the heel, a circular plate is provided on the inner side of the reinforcement ring, and the circular plate is embedded in the inside of the circular groove.

[0012] Preferably, a clamping plate is provided inside the circular plate, a clamping slot is provided inside the circular slot, and a clamping block is embedded inside the clamping slot.

[0013] The three-dimensional breathable TPU material heel structure of the utility model has the following advantages:

[0014] 1. The three-dimensional breathable TPU material heel structure can improve the breathability of the heel by installing a breathable hole, a waterproof breathable membrane, an embedded groove, an anti-slip strip and other structures at the bottom of the heel. It only needs to install the waterproof breathable membrane in the breathable hole, and then install the anti-slip strip in the embedded groove. This can not only improve the breathability of the breathable hole, but also improve the anti-slip effect of the heel, and prevent stones from blocking the breathable hole. Therefore, the breathability is strong when in use;

[0015] 2. The three-dimensional breathable TPU material heel structure can improve the support of the heel by installing a lower ring body, a reinforcement ring, a lower ring body, a clamping block, a circular plate and other structures on the outside of the heel. The upper ring body and the lower ring body are connected to the heel by bonding, and the circular plate on the inner side of the reinforcement ring and the clamping plate are clamped to the outer side of the heel. In this way, the support strength of the heel can be improved when stepping on the heel, reducing the possibility of collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-4 As shown, the utility model discloses a three-dimensional breathable TPU material heel structure, comprising a heel 1, a reinforcing plate 7 embedded inside the heel 1, and the reinforcing plate 7 is installed to improve the strength inside the heel 1, an air hole 2 is provided at the bottom of the heel 1, a waterproof breathable membrane 3 is embedded inside the air hole 2, an embedding groove 4 is provided at the bottom of the heel 1, and the number of the embedding grooves 4 is provided in two groups, and an anti-slip strip 5 is embedded inside the embedding groove 4, and by installing the air hole 2, the waterproof breathable membrane 3, the embedding groove 4, and the anti-slip strip 5 at the bottom of the heel 1, not only the air permeability of the air hole 2 can be improved, but also the anti-slip effect of the heel 1 can be improved, and stones can be prevented from blocking the air hole 2, so that the air permeability is relatively strong during use.

[0029] A reinforcing ring 12 is provided on the outside of the heel 1, an upper ring body 10 is provided on the top of the reinforcing ring 12, and a lower ring body 11 is provided on the bottom of the reinforcing ring 12. By installing the lower ring body 11, the reinforcing ring 12, and the lower ring body 11 on the outside of the heel 1, the supporting strength of the heel 1 can be improved when stepping on the heel 1, thereby reducing the possibility of collapse.

[0030] A slot 6 is provided inside the shoe heel 1 , a reinforcing plate 7 is embedded inside the slot 6 , and the bottom of the reinforcing plate 7 is connected to the vertical plate 17 . The slot 6 facilitates the installation of the reinforcing plate 7 inside the shoe heel 1 .

[0031] The interior of the vertical plate 17 is embedded with a hexagon socket bolt 9, and the exterior of the heel 1 is provided with a threaded hole 8, and the hexagon socket bolt 9 is threadedly connected to the threaded hole 8. By installing the hexagon socket bolt 9, the reinforcing plate 7 on the top of the vertical plate 17 can be conveniently fixed to the interior of the heel 1.

[0032] A circular groove 14 is formed on the outside of the shoe heel 1 , a circular plate 13 is provided on the inner side of the reinforcing ring 12 , and the circular plate 13 is embedded inside the circular groove 14 . The circular groove 14 and the circular plate 13 facilitate the preliminary fixation of the reinforcing ring 12 and the shoe heel 1 .

[0033] A clamping plate is provided inside the circular plate 13 , a clamping groove 15 is provided inside the circular groove 14 , a clamping block 16 is embedded inside the clamping groove 15 , and the clamping block 16 and the clamping groove 15 make the connection between the reinforcing ring 12 and the shoe heel 1 more firmly.

[0034] The working principle of the three-dimensional breathable TPU material heel structure: when using the heel 1, it is first necessary to place it in the corresponding position, and then the user holds the heel 1 to pick it up and move it. After moving it to the specified position, the heel 1 is placed on a plane. In order to prevent the heel 1 from being sunken due to long-term trampling, the lower ring body 11, the reinforcement ring 12, the lower ring body 11, the clamping block 16, the circular plate 13 and other structures are installed on the outside. First, the upper ring body 10 and the lower ring body 11 are connected to the heel 1 by bonding, and at the same time, a circular groove 14 and a clamping groove 15 are opened on the outside of the heel 1, and then the circular plate 13 on the inner side of the reinforcement ring 12 is inserted into the circular groove 14, and the clamping plate is clamped in the clamping groove 15. In this way, the heel 1 can be improved when stepping on the heel 1. The supporting strength is improved to reduce the collapse. At the same time, a slot 6 and a threaded hole 8 are opened on the side of the heel 1. The reinforcing plate 7 is now inserted into the slot 6, and then the hexagon socket bolt 9 is taken out and threadedly connected to the threaded hole 8, which can not only play a fixing role, but also improve the strength of the heel 1. Secondly, the air hole 2, the waterproof breathable membrane 3, the embedded groove 4, the anti-slip strip 5 and other structures are installed at the bottom of the heel 1. It is only necessary to install the waterproof breathable membrane 3 in the air hole 2, and then install the anti-slip strip 5 in the embedded groove 4. This not only improves the air permeability of the air hole 2, but also prevents stones from blocking the air hole 2, and also improves the anti-slip effect of the heel 1. Therefore, the air permeability is strong during use. However, when the anti-slip strip 5 is severely worn, a new anti-slip strip 5 can be taken out for replacement.
