Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

Embodiment

The utility model embodiment provides a kind of adjustable physical education jumping stand, see Fig. 1, Fig. 2, described adjustable physical education jumping stand comprises base assembly 1, the adjustment assembly 2 be connected with base assembly 1, the Buffer Unit 3, the cross bar assembly 4 that is connected with Buffer Unit 3 that are connected with adjustment assembly 2;

Base assembly 1 comprises the first base 5, match with the first base 5 the second base 6 arranged; First base 5 is all identical with the second base 6 structure function, is only described in detail for the first base 5 in the utility model embodiment;

First base 5 comprise pin bar 11, the cross support arm 12 be connected with pin bar 11, by bearing pin and cross support arm 12 folding be connected oblique fulcrum bar 14, be arranged on roll wheel assembly 13 bottom oblique fulcrum bar 14; Cross support arm 12 is provided with cross support arm locating slot 121, one end is provided with cross support arm locating dowel 122; Oblique fulcrum bar 14 is provided with oblique fulcrum bar locating dowel 141, one end is provided with oblique fulcrum bar locating slot 142;
