Referring to fig. 1-5, the present utility model provides a stably supported rubber sports sole, which comprises an EVA midsole 3, a half sole RB outsole 4 and a heel RB outsole 5, wherein a first embedded groove 31 is separately provided at the middle waist of the EVA midsole 3, a second embedded groove 32 is provided at the half sole portion of the EVA midsole 3, a third embedded groove 33 is provided at the heel portion of the EVA midsole 3, a first protrusion 41 is provided on the half sole RB outsole 4 and is engaged with the second embedded groove 32, and a second protrusion 51 is provided on the heel outsole 5 and engaged with the third embedded groove 33;

The rubber sport sole further comprises a supporting body 1 and a supporting sheet 2, wherein the supporting body 1 is matched with the supporting body 1 in the first embedded groove 31, the supporting sheet 2 comprises a first elastic sheet body 21 matched between the first bulge 41 and the inner wall of the second embedded groove 32, a second elastic sheet body 22 matched between the second bulge 51 and the inner wall of the third embedded groove 33, and a supporting sheet body 23 arranged between the first elastic sheet body 21 and the second elastic sheet body 22 and used for supporting the supporting body 1;

When the rubber middle waist is combined with the sports shoe sole, the supporting body 1 is arranged in the first embedded groove 31, and the supporting part can be used for supporting the arch part of the foot at the middle waist of the sports shoe sole, so that the sports force of the foot is facilitated, wherein the bearing sheet body 23 of the supporting sheet 2 is positioned below the supporting body 1 to bear the supporting body 1, the first elastic sheet body 21 of the supporting sheet 2 can extend into the second embedded groove 32, the second elastic sheet body 22 of the supporting sheet 2 can extend into the third embedded groove 33, the design can improve the combined area of the supporting sheet 2 and the sports shoe, and the supporting performance of the supporting sheet 2 can be improved, and the supporting sheet 2 can prevent the shoe sole from being excessively turned inwards or outwards, so that the sports shoe can adapt to more environments.

In this embodiment, the cross section of the support body 1 includes an arc-shaped upper edge 12, a support side edge 13 and a clamping bottom edge 14, an included angle between the arc-shaped upper edge 12 and the support side edge 13 is an acute angle, the arc-shaped upper edge 12 and the support side edge 13 are in arc transition connection, and the arc-shaped upper edge 12, the support side edge 13 and the clamping bottom edge 14 are surrounded to form an oblique tooth structure. The arc surface formed by the arc upper edge 12 of the support body 1 has an arc design which can be more adhered to the arch part of the foot to form a better supporting effect, and because the overall shape is similar to a helical tooth structure, when the support body 1 is stressed, the support side edge 13 can press the EVA midsole 3 and deflect towards the heel part of the EVA midsole 3, and at the moment, the EVA midsole 3 is pressed through the support body 1 to give a forward elastic thrust to the arch part of the foot.

In this embodiment, the bottom edge 14 is arc-shaped, and the outer arc surface of the bottom edge 14 is set inward, in the length direction of the EVA midsole 3, the supporting sheet 23 of the supporting sheet 2 is arc-shaped, and the outer arc surface of the supporting sheet 23 is adapted to the inner arc surface of the bottom edge 14 of the supporting body 1. The bearing sheet body 23 has a better bearing and supporting effect in an arch structure.

In this embodiment, the first elastic sheet 21 is formed with a plurality of first helical protrusions 211 along the length direction of the EVA midsole 3, and the inclined surfaces of the first helical protrusions 211 face the half sole portion of the EVA midsole 3, and the second elastic sheet 22 is formed with a plurality of second helical protrusions 221 along the length direction of the midsole, and the inclined surfaces of the second helical protrusions 221 face the heel portion of the EVA midsole 3.

After the first elastic sheet body 21 and the second elastic sheet body 22 of the supporting sheet 2 are respectively embedded into the second embedded groove 32 and the third embedded groove 33, the first helical tooth protrusions 211 of the first elastic sheet body 21 and the second helical tooth protrusions of the second elastic sheet body 22 can form barb structures, so that the bonding strength of the first elastic sheet body 21, the second elastic sheet body 22 and the EVA midsole 3 can be improved, the first elastic sheet body 21 and the second elastic sheet body 22 are prevented from axially sliding when the supporting body 1 is stressed, and the supporting effect of the supporting body 1 is improved;

Secondly, the first helical tooth protrusion 211 and the second helical tooth protrusion can respectively form a 'reinforcing rib' in the width direction of the first elastic sheet body 21 and the second elastic sheet body 22, so that the strength of the first elastic sheet body 21 and the second elastic sheet body 22 in the width direction of the EVA midsole 3 is improved, axial torsion of the sole in the movement process is avoided, and the foot is protected.

Further, the first helical protrusions 211 are formed by continuously bending the first elastic sheet 21, and the second helical protrusions 221 are formed by continuously bending the second elastic sheet 22.

Based on the above design, not only the bonding strength of the support sheet 2 and the EVA midsole 3 is increased, but also the bonding strength of the support sheet 2 and the half sole RB outsole 4 and the heel RB outsole 5 is increased;

Secondly, the design can prevent the sole from axial torsion in the movement process, so that the sole has certain axial flexibility, and the sole can be more attached to the foot in the movement process;

In addition, the design also enables the first helical tooth protrusion 211 and the second helical tooth protrusion 221 to have better elastic acting force, so that the sole has higher efficient rebound performance.

Specifically, in the movement process, the heel is generally grounded first, in this process, the inclined surface of the second helical tooth protrusion 221 faces the heel, and the bent portion of the second helical tooth protrusion 221 can be bent and deformed in the grounding process, so that a more efficient rebound force is fed back, and when the sole is completely contacted with the ground, the inclined surface of the first helical tooth protrusion 211 faces the half sole, so that the bent portion of the second helical tooth protrusion 221 is bent and deformed, so that a more efficient rebound force is fed back, and the feedback rebound force forwards can provide a better thrust for the foot.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
