Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a high-protection casual shoe sole.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] The utility model provides a high-protection casual shoe sole, comprising a mid-bottom layer, an anti-puncture layer and an outer bottom layer sequentially bonded and fixed to the bottom end of the mid-bottom layer, and an inner bottom layer bonded and fixed to the top end of the mid-bottom layer;

[0007] The outer bottom layer includes a base sheet layer fixedly attached to the middle bottom layer, a plurality of groups of anti-skid convex patterns fixedly arranged at the bottom end of the base sheet layer, and a gap formed between every two adjacent groups of anti-skid convex patterns and the base sheet layer;

[0008] The corresponding parts of the plurality of groups of anti-slip convex patterns directly above the anti-puncture layer serve as a resistance-reducing area and the thickness of the area is less than the thickness of the remaining parts of the anti-puncture layer.

[0012] The beneficial effects of the utility model are as follows:

[0013] By using the corresponding part of the anti-puncture layer 4 just above the several groups of anti-slip ridges 22 as a resistance reduction area and having a thickness less than the thickness of the rest of the anti-puncture layer 4, the anti-puncture strength of the anti-slip ridges 22 and the gap 23 is balanced, the material of the anti-puncture layer 4 is saved, the overall weight can be reduced, and the comfort is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] Figure numerals: middle bottom layer-1, outer bottom layer-2, inner bottom layer-3, anti-puncture layer-4, groove-5, base sheet layer-21, anti-slip ridge-22, gap-23, through hole-41. DETAILED DESCRIPTION Embodiment 1:

[0016] like Figure 1 As shown, this embodiment proposes: a highly protective casual shoe sole, comprising a mid-bottom layer 1, an anti-puncture layer 4 and an outer bottom layer 2 sequentially bonded and fixed to the bottom end of the mid-bottom layer 1, and an inner bottom layer 3 bonded and fixed to the top of the mid-bottom layer 1 (as shown in the figure, the inner bottom layer 3, the mid-bottom layer 1, the anti-puncture layer 4 and the outer bottom layer 2 are sequentially arranged from top to bottom, and can all be connected and fixed by means of strong glue or the like);

[0017] The material of the outer bottom layer 2 can be rubber or polyurethane, etc., which provides better grip and wear protection;

[0018] The material of the middle bottom layer 1 can be EVA (ethylene-vinyl acetate copolymer) and the like, which is mainly responsible for shock absorption, energy feedback and providing wearing comfort;

[0019] The material of the inner bottom layer 3 can be EVA (ethylene-vinyl acetate copolymer) or PU (polyurethane), etc. EVA is light and has good shock absorption, while PU is more durable and can provide better support and resilience:

[0020] The outer bottom layer 2 includes a base layer 21 fixedly attached to the middle bottom layer 1, a plurality of groups of anti-skid convex patterns 22 fixedly arranged at the bottom end of the base layer 21, and gaps 23 formed between every two adjacent groups of anti-skid convex patterns 22 and the base layer 21 (the base layer 21 and the anti-skid convex patterns 22 can be integrally formed, the anti-skid convex patterns 22 can be convex dots or convex strips, etc., and the two adjacent groups of anti-skid convex patterns 22 are separated by the gap 23 to ensure the application of the anti-skid function);

[0021] The corresponding parts of the anti-puncture layer 4 just above the several groups of anti-slip ridges 22 serve as reduced resistance areas and their thickness is less than the thickness of the remaining parts of the anti-puncture layer 4 (as shown in the figure, on the surface of the anti-puncture layer 4 mapped just above the anti-slip ridges 22, the anti-puncture ability of this position is greater than that of the surface of the anti-puncture layer 4 mapped just above the gaps 23. At this time, the thickness of the anti-puncture layer 4 just above the anti-slip ridges 22 is reduced, that is, the anti-puncture strength of the anti-slip ridges 22 and the gaps 23 is balanced, thereby saving material usage of the anti-puncture layer 4, reducing the overall weight, and improving comfort).

[0022] As shown in the figure, further, the reduced resistance area of ​​the reduced thickness anti-puncture layer 4 may not be directly provided to form a through hole 41 penetrating the anti-puncture layer 4 from top to bottom. Embodiment 2:

[0023] like Figure 1 As shown, the difference from Example 1 is that the puncture-resistant layer 4 is made of soft material (it can be a fabric layer woven from Kevlar fibers, etc., which has strong tensile and puncture resistance).

[0024] A groove 5 is provided between the outer bottom layer 2 and the middle bottom layer 1 for the anti-puncture layer 4 to fit in, and the outer bottom layer 2 and the middle bottom layer 1 are fitted and fixed (such as Figure 1 As shown, a groove 5 is provided at the top of the outer bottom layer 2 to provide a placement space for setting the position of the anti-puncture layer 4, so that the position can be accurately determined and manufacturing is facilitated).

[0025] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
