Abstract

The utility model discloses a training is with hurdling, including U die bed seat and stand, the both ends symmetry is equipped with the stand about the front end of U die bed seat, the inside of stand all is equipped with the telescopic link, the upper end surface of telescopic link is equipped with the arc groove, arc groove central authorities open there is the internal thread hole, top arc inslot between the telescopic link is through the fixed movable cross rod of the horizontal activity of locking dish, the rear end face central authorities equidistance of stand has left the catching groove, vertical adjustment tank is connected to the opening part of catching groove. This training is with hurdling is when the needs training, with the movable cross rod of stand top through the locking pine that spirals for movable cross rod and telescopic link break away from to be put at the arc inslot, can effectively prevent the trainer take place when the training error run into the horizontal pole lead to the fact whole hurdle to topple over accidentally injure the trainer, the security of training improves, detain pole movable mounting and in the catching groove of stand, can realize the regulation of telescopic link height, the convenient not training of co -altitude through adjusting.

Description

A kind of training hurdle

Technical field

This utility model relates to hurdling technique field, is specially a kind of training hurdle.

Background technology

Hurdle campaign refers in a certain distance, strides across the height of regulation and the hurdle frame of quantity, generally be it is believed that it is a technical stronger sprint events.

Along with China is hurdled the appearance of famous person (such as Liu Xiang), domestic hurdle campaign becomes more and more popular, along with the development of hurdle campaign and popular, increasing people recognizes that hurdling is an in the pink of condition and interesting sports item, and also begins to obtain quickly popularizing in each middle and primary schools in hurdle campaign project.Along with the development of hurdle campaign, as an important sports equipment of hurdle campaign, the type hurdled is the most varied, meets the use demand of different crowd training hurdle campaign.Physical ability and sports qualities owing to participating in the personnel of hurdle campaign training are uneven, therefore, if trainer uses regular hurdling or traditional training hurdle, if hurdling in a flash, when foot or leg touch and hurdle, it is easy to will hurdle and knock over, and not only easily cause unnecessary trouble, and, it is also very easy to cause trainer injured.Therefore, the problem that the safety of hurdle campaign also increasingly becomes the head of a family and teachers worry.Meanwhile, based on above factor, Also there are a lot of classmates or elementary training person because being afraid of to be tripped by railing and dare not the most further be attempted, losing the good opportunity utilizing hurdle campaign to take exercises, and, the height hurdled mostly is definite value, it is impossible to regulation, it is impossible to meet the training of differing heights.

Utility model content

The purpose of this utility model is to provide a kind of training hurdle, with the problem solving to propose in above-mentioned background technology.

nullFor achieving the above object，This utility model following technical scheme of offer: a kind of training hurdle，Including U-shaped base and column，The two ends, left and right, front end of described U-shaped base are arranged with column，The inside of described column is equipped with expansion link，The upper end face of described expansion link is provided with arc groove，Described arc groove central authorities have internal thread hole，By the laterally movable fixing movable cross bar of locking plate in top arc groove between described expansion link，The rear end face central authorities of described column are equidistant has catching groove，The opening part of described catching groove connects vertical adjustment groove，It is embedded with elastic buckles at the bottom margin of described catching groove，The regulation button bar of described expansion link lower end is movably arranged in catching groove，Square groove is had inside the end of described cross bar left and right，The lower end of described locking plate is provided with screw rod，The central authorities of described screw rod are provided with limited block，Described limited block is arranged in square groove.

Preferably, described U-shaped base, column, expansion link and movable cross bar are cylindrical structure.

Preferably, described regulation button bar is equipped with antiskid thread with the surface of locking plate.

Preferably, the bottom of described elastic buckles is provided with spring.

Preferably, in described screw rod is movably arranged on the internal thread hole of arc rooved face.

Compared with prior art, the beneficial effects of the utility model are: this training hurdle, when needs are trained, movable cross bar above column is unscrewed by locking plate, movable cross bar is departed from expansion link be placed in arc groove, can effectively prevent trainer from occurring error to encounter cross bar when training causes whole hurdling to topple over accidental injury trainer, improve the safety of training, it is movably arranged in the catching groove of column by regulation button bar, the regulation of expansion link height can be realized, facilitate the training of differing heights.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation；

Fig. 2 is this utility model left view cross-sectional view.

In figure: 1U type base, 2 columns, 3 expansion links, 31 arc grooves, 32 regulation button bars, 33 internal thread holes, 4 movable cross bar, 41 square grooves, 5 vertical adjustment grooves, 51 catching grooves, 52 elastic buckles, 6 locking plates, 61 screw rods, 62 limited blocks.

Detailed description of the invention
