The elastic supporting legs comprise inserting parts which can be inserted on the panel, and a plurality of arc-shaped supporting strips which are dispersed from the bottom of the inserting parts to the periphery and are bent downwards; the bottom ends of the arc-shaped supporting strips are in contact with the ground, and the elastic supporting legs form elastic support for the sports floor due to the self deformation of the arc-shaped supporting strips.

Based on the design concept, the elastic legs of the arc-shaped elastic structure of the present embodiment are inserted into the bottom of the panel 1 of the sports floor and partially protrude out of the bottom end surface of the sports floor. One exemplary structure is shown in fig. 1 and 2, and mainly includes a plug portion 300 that is plugged into the panel 1, and a plurality of arc-shaped support bars 30 that are diverged from the bottom of the plug portion 300 toward the periphery and are bent downward. The elastic legs form elastic support for the sports floor due to the self-deformation of each of the arc-shaped support bars 30.

As can be seen from fig. 3 and 4, the plug portion 300 is a column structure and can be inserted into the socket 10 disposed at the bottom of the panel 1. In this embodiment, the cross section of the insertion part 300 is "cross" shaped, so that the design is convenient for manufacturing and installation, and the insertion part 300 is not easy to separate from the insertion seat 10.

It should be noted that, the number of the arc support bars 30 may be three or five other than four evenly spaced at the circle center, as shown in fig. 2, two arc support bars 30 may also achieve the elastic support effect, but the elastic support effect of the panel 1 by arranging four arc support bars 30 is the best.

In order to enhance the structural strength of arch support bar 30 itself, the bottom end is bent to form leg 302. The arrangement of the support legs 302 increases the contact area between the arc-shaped support strip 30 and the ground, which is beneficial to improving the support stability of the elastic support legs.

In addition, the distance between the bottom end surface of the sports floor and the upper surface of the panel 1 is the floor height H; the radius R of the circle is between 0.3 and 0.7 times of the height H of the floor, and the extending height H' of the elastic supporting legs extending out of the bottom end face of the sports floor is less than or equal to 5 mm.
