This track and field is with ware of hurdling simple structure, can be fine in the use play the cushioning effect to, can not fall down messenger's ware practicality of the ware of should hurdling of having used more convenient, great improvement of should hurdling easily.
Description
Technical field
The utility model relates to sports apparatus technical field, is specially a kind of track and field hurdle.
Background technology
Hurdle race campaign originates from Britain.During 17th to 18 century, some ground pastoral industries of Britain are quite flourishing, and herdsman often need cross over corral, catch up with the livestock run away.In red-letter day, some like that lively young herdsman also usually holds the game of jumping over sheepfold, and they move fence on level land to, if several height and the similar obstacle of sheepfold, see that who can run up front, and Here it is hurdles the blank of match.Hurdle race is in certain distance, strides across height and the hurdle frame of quantity, the technical stronger sprint events of regulation.International tournament man is 110 meter high hurdle, and hurdle is high 106 centimetres, column number 10; Woman is M 100 low hurdles, and hurdle is high 84 centimetres, column number 10.
In hurdle race, hurdle is absolutely necessary sports apparatus, but traditional hurdle is in use once touch hurdle and will make its disequilibrium and fall down, not only give again to set and bring very large time waste, and also can damage sportsman time serious.
Utility model content
The purpose of this utility model is to provide a kind of track and field hurdle, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of track and field hurdle, comprise two groups of poles be parallel to each other, described pole comprises the first telescopic joint, the sidewall of described first telescopic joint is fixed with spacing preiection by elastic plectrum, described first telescopic joint is plugged on the inner chamber of the second telescopic joint, and the second telescopic joint evenly has the spacing hole suitable with the second spacing preiection, the bottom of described pole is fixedly connected with the top of the first back-moving spring, the bottom of described first back-moving spring is fixed on the arc-shaped groove bottom of arc-shaped base, the top of described pole is plugged on the inner chamber of lock sleeve, described lock sleeve is separately fixed at the two ends, left and right across bar, and the sidewall of lock sleeve is also fixed with the clamping screw suitable with pole, the opposed inner walls of the arc groove of described arc-shaped base is all fixed with the second back-moving spring, the top of described second back-moving spring is fixed with the cushion pad suitable with pole, and the second back-moving spring is symmetrical about the first back-moving spring.
Preferably, the bottom of described first back-moving spring and the second back-moving spring is all by be spirally connected or the mode of clamping is fixedly connected with the arcuate recess sections of arc-shaped base.
Preferably, described cushion pad is formed by stacking by being no less than ten groups of rubber rings, and is also interspersed with strengthening rib strip between rubber ring.
Preferably, the outer wall of described pole is also carved with the scale suitable with lock sleeve.
Compared with prior art, the beneficial effects of the utility model are: this track and field hurdle structure is simple, in use, if sportsman encounters because of carelessness across bar, due to the cushioning effect of the first buffer spring, sportsman is made to fall down easily and to meet accident, and pass through the interaction of the first buffer spring and the second buffer spring, make this hurdle also can keep original position after being subject to percussion, and, the base of this hurdle adopts arc-shaped base, make this base in use in time hurdle generation sharp impacts also can not fall down easily, the sportsman made is more convenient in training use procedure.
