Embodiment Construction
[0015] see figure 1 and Figure 4 As shown, it is the first embodiment of the present invention. This embodiment is composed of rigid ribs 1 and flexible strips 2 alternately distributed on the rigid surface. The cross-sectional shape of the rigid rib 1 is semicircular, and its radius R is 3mm. The spacing L between the rigid ribs 1 is 10mm, and the thickness N of the flexible strips 2 is 2mm.
[0016] see figure 2 and Figure 5 As shown, it is the second embodiment of the present invention. This embodiment is composed of rigid ribs 1 and flexible strips 2 distributed alternately and alternately on the rigid surface. The cross-sectional shape of the rigid rib 1 is triangular, and its triangular vertex angle α is 60° , the height H from the apex to the bottom is 5mm, the distance L between the rigid ribs 1 is 8mm, and the thickness N of the flexible strip 2 is 2mm.
