A lockable high jump device for college assessment training

Abstract

The invention relates to a lockable high jump device for college examination training. The lockable high jump device comprises left-right-symmetric bases, rubber bags are fixedly connected to the topsof the bases, and lead screws are fixedly connected to the tops of the rubber bags. The rubber bags are used for stably supporting the lead screws and can also freely fall when being impacted by an athlete and recover. A fixed rod assembly is movably connected between the two lead screws in a threaded connection manner, supporting frames are fixedly connected to the tops of the lead screws, loudspeakers are arranged on the supporting frames, up-down-symmetric connecting rods are fixedly connected onto the end faces, close to each other, of the lead screws, and rulers are fixedly connected tothe tail ends of the other ends of the connecting rods; lifting machine bodies are movably connected onto the lead screws in a threaded connection manner. The high jump height can be accurately, safely and stably measured in multiple ways, danger caused when the body of the athlete is obstructed by a rod is prevented, the anti-cheating function is configured, and the problem that the body of the athlete is impacted when hard supporting is adopted for integral supporting is solved.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a lockable high jump device for college assessment training. Background technique [0002] In sports competitions, high jump is an essential basic skill item. Under the stage, athletes need to practice and take exams. Because the existing high-tech high jump equipment is expensive and limited in number, it is impossible to use slides like large competition venues. Therefore, the usual method of measuring and adjudicating the results of the competition is to use the horizontal bar to hang at the specified height. When the athlete fails to pass the crossbar of the specified height, it is likely to be blocked by the crossbar and cause a fall, which is more dangerous. In official competitions, the high jump has common high jump and pole vault, and the different impact force is also different at different heights. The support rods at both ends of the existing high jump device may caus...

[0002] In sports competitions, high jump is an essential basic skill item. Under the stage, athletes need to practice and take exams. Because the existing high-tech high jump equipment is expensive and limited in number, it is impossible to use slides like large competition venues. Therefore, the usual method of measuring and adjudicating the results of the competition is to use the horizontal bar to hang at the specified height. When the athlete fails to pass the crossbar of the specified height, it is likely to be blocked by the crossbar and cause a fall, which is more dangerous

In official competitions, the high jump has common high jump and pole vault, and the different impact force is also different at different heights. The support rods at both ends of the existing high jump device may cause danger to the athletes. The existing high jump device is relatively simple due to the measurement , it is impossible to explain the controversial situation, and it cannot effectively prevent the problem of cheating in the competition, which will affect the performance of the athletes and bring unnecessary troubles to the high jump competition
