A track and field hurdle frame structure with protective effect

Abstract

The invention discloses a track and field hurdle frame structure with protective effect, which comprises a pair of support legs with the same structure, a pair of support sleeves with the same structure and a crossbeam, and a pair of support sleeves are arranged on a pair of the support sleeves respectively. on one end of the supporting legs, and are both rotatably connected to the supporting legs, the beam is arranged between a pair of the supporting sleeves, and a There is a folding storage mechanism, and a flexible buffer mechanism is provided on the crossbeam. By designing a folding support mechanism, the present invention enables folding and storage between the support legs and the support sleeve. At the same time, an adjustable lifting mechanism is set in the support sleeve, which can A variety of height adjustments are made to the beam, and the flexible buffer protection mechanism on the beam can avoid the damage to the legs when the user's leg hits the beam during use to the greatest extent. The structure is simple and stable, and it is fast and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a track and field hurdle frame structure with protective effect. Background technique [0002] Hurdles is a sprint event with a fixed number, fixed distance, and fixed height hurdles on the way. It is also an event with more complicated technology, stronger rhythm, and higher exercise value in track and field sports. Engaging in hurdle running can not only effectively develop physical qualities such as speed, jumping ability, flexibility and agility, but also cultivate the will qualities of bravery, tenacity, decisiveness and overcoming difficulties. [0003] In the use of hurdles for track and field sports training, the height of the training hurdles should often be adjusted according to different usage requirements. However, in the prior art, the overall structure of the hurdles for track and field sports training is relatively single. Under the action of the hurdle b...

Problems solved by technology

[0004] The object of the present invention is to solve the above-mentioned problems by designing a track and field hurdle frame structure with a protective effect. It is not firm, and under the action of the hurdle beam and gravity, the hurdle beam slowly descends downward, resulting in inaccurate adjustment of the height of the hurdle for track and field sports training, so that the athletes cannot achieve the training effect. And the phenomenon that the legs collide with the railing board, due to the high strength and high hardness of the railing board, not only is it easy to cause injury to the practitioner or damage to the hurdle frame, but also cause psychological fear to the practitioner
