Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Example 1:

as shown in fig. 1-3, a supercritical physical foaming EVA sole comprises a sole body 1, a rebound part 2 fixed on the upper side of the sole body 1, the upper side edge of the sole body 1 extends upwards to be arranged, the heel and the toe cap of the sole body 1 are provided with a cavity 9 and a jack, the rebound part 2 comprises a rebound part 2 body located between the cavity 9 and the jack, a plurality of connecting columns and bosses arranged on the lower side of the rebound part 2 body, the connecting columns and the jacks are fixedly connected, and the bosses extend to the bottom of the cavity 9.

Its theory of action does, through setting up resilience piece 2, jack that the spliced pole on the resilience piece 2 inserted on the sole body 1 carries out fixed connection, the mode that utilizes to add the auxiliary member increases the resilience force, resilience piece 2 can improve the resilience effect so, because one side of resilience piece 2 is equipped with the bellying, the bellying downwardly extending is to in the cavity 9 of sole body 1, the bottom of the tight cavity 9 in top, cavity 9 is located the heel side of sole body 1, resilience piece 2 body is the characteristic that has compressible resilience, the heel is forced to press earlier and is retracted resilience piece 2, buffer by sole body 1 again, it stores on resilience piece 2 to have some energy, resilience piece 2 rebounds and provides the resilience force, realize that the sole not only has the effect of shock attenuation buffering, still have certain resilience force, improve the practicality of shoes in the life.

In practical application, the protruding portion includes a first protrusion 10 and a second protrusion 11 arranged around the first protrusion 10, and the first protrusion 10 and the second protrusion 11 tightly push against the bottom of the cavity 9 respectively.

In this embodiment, several protrusions are arranged in a specific structure so that the pressure can be uniformly distributed on the heel side of the resilient member 2, and each protrusion can store the average compression energy, for example, if a first protrusion 10 and a second protrusion 11 are provided, the main pressure is concentrated on the first protrusion 10, and the second protrusion 11 arranged around the first protrusion 10 assists the rebound, thereby improving the comfort.

In practical use, the first protrusion 10 and the second protrusion 11 are both of a hemispherical structure.

Preferably, the shape structure of the first protrusion 10 and the second protrusion 11 is arranged, so that the compressible rebound effect of the protrusions is increased.

In the implementation application, the bottom of sole body 1 is equipped with downwardly extending's buffering portion 5, be equipped with the buffering hole 4 that runs through sole body 1 level both sides on the buffering portion 5, the hole punches a hole for the parallelogram structure of left and right side slope arrangement.

The sole body 1 so can cushion the shock attenuation, not only utilizes the characteristic of material supercritical physics foaming EVA, still utilizes its distinctive physical structure to cushion the shock attenuation, and this special construction is a plurality of dashpot holes 4, and the buffering shock attenuation principle of dashpot hole 4 does, and dashpot hole 4 is parallelogram structure, and the left and right sides arranges for the hypotenuse, when receiving the pressure that comes to supreme lower, and the vertical compression deformation of dashpot hole 4 to improve buffering shock attenuation effect.

In specific implementation, the resilient member 2 is made of elastic rubber; so that the resilient member 2 is self-carrying with a certain resilient force.

The specific structure of sole body 1 does, sole body 1 includes the big end 8, sets up insole 6 at 8 upsides in the big end, big end 8 and insole 6 are integrated into one piece, cavity 9 and jack setting are on insole 6, the upside border of insole 6 upwards extends and arranges.

As a further improvement, the outsole 8 is a cavity structure with an upward opening, a plurality of stepped stripe holes 3 arranged horizontally are respectively arranged on two sides of the outsole 8, the stripe holes 3 penetrate through the inner side and the outer side of the outsole 8, and the lower side of the midsole 6 is arranged inside the outsole 8.

The improved effect is that the cavity structure of the outsole 8 and the stripe holes 3 on the two sides are arranged, so that the outsole 8 not only has the effect of buffering and damping at the bottom, but also has the effect of buffering and damping on the side wall of the edge; the principle of the shock absorption and buffering of the stripe holes 3 is that the stripe holes 3 have a space which can be compressed up and down by utilizing the unique structure of the stripe holes 3 and a plurality of step-shaped through holes which are horizontally arranged; because of the excess openness of the outsole 8, the underside of the midsole 6 needs to be embedded within the outsole 8 to provide support and resiliency.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
