Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, an arrow-shaped twelve-piece volleyball includes six first connecting pieces 1 with the same shape and six second connecting pieces 2 with the same shape, and after the volleyball is unfolded in a plane, two adjacent first connecting pieces 1 are respectively positioned at two sides of the width of the second connecting pieces 2 (i.e. the first connecting pieces 1 and the second connecting pieces 2 are arranged at intervals).
As shown in fig. 3, after the first connecting piece 1 is unfolded in a plane, the first connecting piece 1 includes two short sides 11 and two long sides 12 which are arranged oppositely, the two short sides 11 and the long sides 12 are sequentially connected end to end at intervals, and the two short sides 11 and the two long sides 12 together enclose an approximately elliptical area, which is the first connecting piece 1.
As shown in fig. 4, the second connecting piece 2 includes a dummy piece 21, the shape and the specification of the dummy piece 21 are the same as those of the first connecting piece 1, the dummy piece 21 also has two long sides 12 and two short sides 11, and arrow-shaped pieces 3 are integrally provided on both sides in the longitudinal direction of the dummy piece 21.
As shown in fig. 4, the arrow-shaped piece 3 includes two arc sides 22 and two straight sides 23, the length of the arc side 22 is half of the length of the short side 11 of the first connecting piece, the two arc sides 22 and the straight sides 23 are symmetrically arranged along the length direction of the virtual piece 21, the two arc sides 22 are respectively connected with the long side 12 of the virtual piece 21, the included angle between the two straight sides 23 is 60 degrees, the length range of the straight sides 23 is 50.35-51.35mm, and 50.35mm is selected in this embodiment.
