Description

Technical Field

[0001] This utility model belongs to the field of footwear technology, specifically, it relates to an elastic heat-insulating shoe sole. Background Technology

[0002] Shoes are items worn on the feet to prevent injury. In the early stages of human civilization, they were mostly straw sandals and cloth shoes. Nowadays, leather shoes, sports shoes, casual shoes, high heels, slippers, and boots are more common. In industrial production, the working environment of workers is relatively complex, which places high demands on the sole materials of workers' shoes.

[0003] Currently, the soles of industrial shoes on the market are generally made of rubber. Due to the limitations of a single material, soles made of a single layer of rubber do not have high temperature resistance. When standing on the high-temperature ground in a high-temperature workshop, the rubber material is easily damaged and becomes unusable. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an elastic heat-insulating shoe sole.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An elastic heat-insulating shoe sole includes a rubber outsole, a heat-insulating ceramic sheet, a lightweight heat-insulating midsole and an EVA topsole. The rubber outsole has a groove inside for placing the lightweight heat-insulating midsole and the EVA topsole. The lower surface of the lightweight heat-insulating midsole is fixed to the inner surface of the groove, and the EVA topsole is fixed to the upper surface of the lightweight heat-insulating midsole.

[0007] The interior of the rubber outsole has cavities for installing multiple reinforcing strips. Each reinforcing strip is fixed to the heat-insulating ceramic plate at the bottom of the rubber outsole by a reinforcing rope. The bottom surface of the heat-insulating ceramic plate has anti-slip grooves and embedding grooves at equal intervals. A heat-resistant rubber strip is fixed inside each embedding groove.

[0008] Optionally, the bottom of the rubber outsole is fixed with positioning strips at equal intervals, and the middle of the positioning strip is provided with a positioning groove for placing the heat insulation ceramic sheet, and the number of positioning strips corresponds one-to-one with the number of heat insulation ceramic sheets.

[0009] Optionally, anti-kick components are fixed inside the front and rear end walls of the rubber outsole, and anti-collision rubber blocks are also fixed on the front and rear end surfaces of the rubber outsole.

[0010] Optionally, the upper end of the bottom layer of the lightweight insulation is fixed with docking positioning posts at equal intervals, and the number of each docking positioning post is the same as the number of docking cavities on the upper and lower surfaces of the EVA.

[0011] Optionally, an antibacterial pad that contacts the bottom of the insole is fixed to the middle of the upper surface of the EVA upper.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] This invention adds a heat-insulating ceramic sheet to the bottom of the rubber outsole. The excellent heat insulation properties of the ceramic sheet ensure that the rubber outsole will not be damaged or deformed due to the high temperature of the workshop floor. In order to improve the comfort of workers, a composite structure is adopted, that is, the upper side of the rubber outsole is also equipped with a lightweight heat-insulating middle and bottom layer and an EVA top layer. The presence of the lightweight heat-insulating middle and bottom layer further improves the heat insulation effect of the device, so that the temperature transfer is not too high and causes discomfort to the wearer. The presence of the EVA top layer not only has a heat insulation effect, but also has elasticity, antibacterial and odor-proof characteristics, improving the wearer's foot feel.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: an elastic heat-insulating shoe sole, including a rubber outsole 1, a heat-insulating ceramic sheet 6, a lightweight heat-insulating mid-layer 2 and an EVA upper outsole 3. The rubber outsole 1 has a groove inside for placing the lightweight heat-insulating mid-layer 2 and the EVA upper outsole 3. The lower surface of the lightweight heat-insulating mid-layer 2 is fixed to the inner surface of the groove, and the EVA upper outsole 3 is fixed to the upper surface of the lightweight heat-insulating mid-layer 2.

[0026] The inner wall of the rubber outsole 1 has cavities for installing multiple reinforcing strips 4. Each reinforcing strip 4 is fixed to the heat-insulating ceramic plate 6 at the bottom of the rubber outsole 1 by a reinforcing rope 5. The bottom surface of the heat-insulating ceramic plate 6 has anti-slip grooves 7 and embedding grooves at equal intervals. Each embedding groove has a heat-resistant rubber strip 8 fixed inside. Considering that the soles of industrial shoes on the market are generally made of rubber, soles made of a single layer of rubber are limited by the single material and do not have high-temperature resistance. When standing on the high-temperature ground of a high-temperature workshop, the rubber material is easily damaged and not conducive to use. This utility model addresses the problem that the rubber outsole 1 has a cavity for installing multiple reinforcing strips 4. The addition of heat-insulating ceramic plates 6 will utilize their excellent heat insulation properties to ensure that the rubber outsole 1 will not be damaged or deformed due to the high temperature of the workshop floor. In order to improve the comfort of workers, a composite structure is adopted, namely, the upper side of the rubber outsole 1 is equipped with a lightweight heat-insulating middle and bottom layer 2 and an EVA top layer 3. The presence of the lightweight heat-insulating middle and bottom layer 2 further improves the heat insulation effect of the device, so that the temperature transfer is not too high and causes discomfort to the wearer. The presence of the EVA top layer 3 not only has a heat insulation effect, but also has elasticity, antibacterial and odor-resistant properties, improving the wearer's foot feel.

[0027] The bottom of the rubber outsole 1 is fixed with positioning strips 9 at equal intervals. The middle of the positioning strip 9 is provided with a positioning groove for placing the heat insulation ceramic sheet 6. The number of positioning strips 9 corresponds one-to-one with the number of heat insulation ceramic sheets 6. The positioning strips 9 facilitate the alignment of the heat insulation ceramic sheet 6 with the reinforcing strip 4 during production. When the heat insulation ceramic sheet 6 is placed into the positioning strip 9, the heat insulation ceramic sheet 6 is located below the reinforcing strip 4. Then, the worker can use the reinforcing rope 5 to sew it.

[0028] The rubber outsole 1 has anti-kick components 10 fixed inside the front and rear end walls, and anti-collision rubber blocks 11 are also fixed on the front and rear end surfaces of the rubber outsole 1. By setting the anti-kick components 10, the front and rear ends of the rubber outsole 1 are reinforced, thereby improving the service life of the easily bumped parts.

[0029] Among them, the upper end of the lightweight insulation middle layer 2 is fixed with docking positioning posts 12 at equal intervals. The number of each docking positioning post 12 is the same as the number of docking cavities on the lower surface of the EVA upper bottom 3. By setting the docking positioning posts 12, it is convenient to complete the docking between the EVA upper bottom 3 and the lightweight insulation middle layer 2. The lightweight insulation middle layer 2 is made of lightweight insulation material, which is a mature existing material. Therefore, the detailed composition is not described in the text.

[0030] Among them, the upper surface of the EVA upper 3 is fixed with an antibacterial pad 13 that contacts the bottom of the insole. The antibacterial pad 13 plays an antibacterial role in the later shoe environment. The antibacterial pad 13 is made of fibers with antibacterial effect.

[0031] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
