Abstract
Description
Technical Field
[0001] The utility model relates to the field of shoe sole technology, in particular to a high-rebound ETPU shock-absorbing sole. Background Art
[0002] ETPU is a new type of polymer material. Specifically, ETPU is expanded thermoplastic polyurethane, also known as popcorn material. This material is composed of countless elastic and lightweight TPU foam balls, forming elliptical non-cross-linked foam particles containing micro-enclosed bubbles, which are shaped like popcorn. ETPU has the characteristics of high resilience and lightweight, and is one of the most elastic foam particles on the market. After pressurized and heated treatment, the volume of this material will increase 10 times. It is widely used in various fields, such as sports field materials and insoles. ETPU material is particularly suitable for the production of sports fields, such as shock-absorbing soles, due to its excellent physical properties and environmental protection characteristics, such as wear resistance, anti-slip, and shock absorption. However, the existing high-rebound ETPU shock-absorbing soles mostly use shock-absorbing springs for shock absorption. Shock-absorbing springs are easily damaged after long-term use, and it is not easy to replace them when damaged, which affects their service life.
[0003] For example, the announcement number is: CN103637504A, a shock-absorbing and explosion-resistant sole, including an outsole, a midsole is arranged inside the outsole, and a foam rubber shock-absorbing layer is provided on the outsole and the midsole from the arch to the heel, and the thickness of the foam rubber shock-absorbing layer gradually decreases from the heel to the arch, a shock-absorbing area is provided in the middle part of the sole of the outsole, shock-absorbing columns are evenly arranged in the shock-absorbing area, and correspondingly, a through hole for inserting the shock-absorbing columns is provided in the middle part of the sole of the midsole, and a buffer grid is provided in the area from the sole to the arch except the shock-absorbing area, and the buffer grid is a convex ridge higher than the upper bottom surface of the outsole. When the ground waves generated by the blast are transmitted from the ground to the human body, the rear part bears about 80% of the human body's weight, and the ground waves it bears are digested and dispersed by the shock-absorbing slow-rebound foam rubber layer and the shock-absorbing spring. The seismic waves borne by the forefoot are diffused to the surroundings through the middle shock-absorbing column through the frequency pendulum, and are digested and dispersed by the buffer grid, thereby achieving a shock-absorbing effect.
[0004] In the above-mentioned shock-absorbing and explosion-resistant sole, the shock-absorbing spring is easily damaged after long-term use, and it is not easy to replace the damaged one, which has high maintenance costs and shortens the service life. Utility Model Content

The elastic pad is snap-fitted to the sole body through the connecting block and the snap-in groove.
