A flexible and convenient track and field hurdle

Abstract

The invention relates to a flexible and convenient track and field hurdle. The flexible and convenient track and field hurdle comprises two hurdle columns, a hurdle transverse rod, a hurdle bottom pillar and supporting pillars, the hurdle transverse rod is installed between the upper ends of the two hurdle columns, the hurdle bottom pillar is installed between the lower ends of the two hurdle columns, and each supporting pillar is installed at the left end of the corresponding hurdle column; each hurdle column comprises the corresponding supporting pillar, a moving pillar, telescopic clampingteeth, a clamping tooth spring, a limiting clamping plate, a limiting connecting pillar, a tilting prevention mechanism, a pushing mechanism, a limiting spring and a pressing shelf. By means of the flexible and convenient track and field hurdle, the problems can be solved that when an existing hurdle is in use, the height and length of the hurdle cannot be adjusted, the hurdle cannot be conveniently moved, the hurdle may be deformed when falling off, and the hidden safety hazard that people may get hurt when the hurdle falls off exists; the height and length of the hurdle can be adjusted, andthe hurdle can be conveniently moved.

Description

technical field [0001] The invention relates to the field of track and field equipment, in particular to a flexible and convenient track and field hurdle. Background technique [0002] The original hurdle movement originated in the United Kingdom, and now hurdle sports is an Olympic event. In international competitions, men's 110-meter high hurdles are 106 cm high and 10 hurdles; women's 100-meter low hurdles are 84 cm high and the number of hurdles 10. At the beginning of the 20th century, a movable "⊥" shaped hurdle appeared, which promoted the development of hurdle technology. In 1935, an "L" shaped hurdle appeared in the competition. The "L" shaped structure is more reasonable and safe. It has been used until now. Today's hurdles are relatively large in size, and it is troublesome to move and transport. Moreover, athletes may be injured in hurdle sports. The specific problems existing in the existing hurdles are as follows. The height and length of the hurdles cannot be ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems, the present invention provides a flexible and convenient track and field hurdle, which can solve the problems that the height and length of the hurdle cannot be adjusted, the hurdle cannot be moved conveniently, and the hurdle will cause problems when the hurdle falls. The deformation of the hurdle, the hidden danger of hurting people when the hurdle falls, etc., can realize the function of adjusting the height and length of the hurdle, and conveniently move the position of the hurdle, and can adjust the height and length of the hurdle. It has the advantages of moving, no deformation of the hurdle when falling across the hurdle, and no hidden danger of injury when falling across the hurdle.
