Topic.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of adjustable track and field is with hurdling, including baffle, telescopic rod, supporting rod and cross bar, the telescopic rod and branch
Strut is two groups, and the telescopic rod includes interior bar and outer bar, is hollow form inside the outer bar, the interior bar lower part is socketed in
In outer bar, the outer bar top is equipped with mounting hole, and the interior bar is fixed by the fixing bolt through mounting hole in outer bar, institute
It states interior bar upper end and is equipped with slot, the baffle lower end is placed in the slot of interior bar and is fixed by fixed screw, the telescopic rod
Inside and rear side are respectively equipped with the first jack and the second jack, and the cross bar both ends and two groups of supporting rod one end are equipped with inserted block,
The cross bar is placed in by the inserted block at its both ends in the first jack of two groups of telescopic rods, and two groups of supporting rods are placed in two by inserted block
In second jack of group telescopic rod.
Further, one group of interior bar top inner side is equipped with laser pen.
Further, two groups of interior bar surfaces are equipped with graduation mark.
Further, baffle both sides upper end is equipped with fixing axle, and the fixing axle is equipped in shaft and shaft fixed
Miniature webcam is installed.
Compared with prior art, the utility model has the advantages that：The adjustable track and field structure of hurdling
Simply, easy to use, due to two groups of telescopic rods, the height hurdled can be adjusted according to different sexes or all ages and classes, together
When top by the graduation mark on laser pen and interior bar to judge two groups of telescopic rods whether in the same horizontal line, avoid making
It is uneven at both ends, training athlete is influenced, due to the miniature webcam in the shaft of baffle both ends, is hurdled in order to record sportsman
When height from column, be conducive to sportsman's summing up experience, it helped to improve results.
