Description

Folding sports hurdle

Technical Field

The utility model relates to a fence field is striden in the sports, specifically is a fence is striden in foldable sports.

Background

The hurdle running is a sprint running project with fixed number, fixed distance and fixed height hurdles arranged on the way, and is also a project with more complex technology, stronger rhythm and higher exercise value in track and field sports. When engaged in cross-track running, not only can effectively develop physical qualities of speed, bouncing force, flexibility, sensitivity and the like, but also can cultivate the will quality of brave, obstinate and stubborn and overcoming difficulty. Hurdles originated in the uk and evolved from a game in which shepherds crossed the sheepfold barrier. The hurdle frame used earliest in hurdle running is a wood bracket or a fence buried on the ground, and a movable inverted T-shaped hurdle frame appears in nine-zero years. In nine or three or five years, people change the T-shaped hurdle frame into the L-shaped hurdle frame, and the other end of the L-shaped hurdle frame supporting leg faces the running direction of the athlete, so that the athlete can overturn forwards by slightly adding resistance, and the fear psychology of the athlete when crossing the hurdle is reduced. The hurdle frame is a sports apparatus needed in the field sports of hurdle running. The hurdle frame is a common sports apparatus, and is used for standard hurdles of sports competitions, training hurdles are also frequently adopted in various sports fitness and training activities, and at present, most of the hurdles are split hurdles with fixed height or adjustable height. The structure of hurdle mainly includes two sill bars and violently locates the horizontal pole between two sill bars, vertically has set firmly a pole setting on every sill bar, has set firmly a breast board at the top of two pole settings.
