Description of drawings

A kind of preferred embodiment structural representation of sole damping device that Fig. 1 provides for the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 1, the sole damping device that the utility model provides comprises the end 2 among the EVA, the rear foot heel at the end 2 is embedded among the EVA is equipped with a plurality of column TPU elastomers 1 that set gradually along the fore-and-aft direction at the end among the EVA, and TPU elastomer 1 is that hollow structure and its axis are vertical with the fore-and-aft direction at the end 2 among the EVA.The fore-and-aft direction at the end 2 refers to the fore-and-aft direction of people's pin among the EVA.In the present embodiment, the quantity of TPU elastomer 1 is three, but, the utility model is not limited to adopt three TPU elastomers 1, the quantity of TPU elastomer 1 can be set, usually according to the flexible in size of the kind of sport footwear and size, sport footwear for football, basketball strenuous exercise project, the volume of TPU elastomer 1 is bigger, and negligible amounts can provide bigger buffer capacity; And for jogging shoes etc., TPU elastomer 1 can be provided with greater number, and volume is less, like this, can provide bigger cushioning ability.

The cross section of TPU elastomer 1 can be annular or oval ring, is the TPU elastomer of oval ring for cross section, and the long axis direction of its cross section is consistent with the fore-and-aft direction at the end among the EVA.Through evidence, the TPU elastomer has remarkable high-tension, high-tensile strength, tough and ageing-resistant characteristic, when adopting cross section to be the TPU elastomer of oval ring, the both sides radian is less up and down because TPU is elastomeric, be beneficial to the bigger lifting surface area of assurance, two ends, left and right sides radian is bigger, is beneficial to when preventing to push stress and too concentrates and rupture.Simultaneously, the long axis direction of TPU elastomer cross section is consistent with the fore-and-aft direction at the end among the EVA, can prevent that the heel local pressure is excessive, the inside and outside upset of control foot.
