Hurdle frame with falling prevention function for physical education

Abstract

The invention relates to the technical field of physical education, in particular to a physical education hurdle with an anti-falling function, which comprises a bottom cylinder, the bottom cylinder is connected with a supporting spring through a partition plate, the supporting spring is connected with a universal wheel through a bottom rod, the bottom rod is connected with a positioning mechanism and a connecting strip, and the partition plate is connected with a fixing spring and a positioning spring through a supporting plate. The fixing spring and the positioning spring are connected with a fixing rod and a positioning rod, the bottom cylinder is connected with a fixing plate and a connecting plate, the fixing plate is connected with a main gear, a driven wheel and a rotating wheel through a driving rod, a driven rod and a stud, the connecting plate is connected with a suction cup through a bottom column, and the partition plate is connected with a supporting cylinder through a compression spring. According to the portable hurdle frame, a plurality of hurdle frames can be conveniently carried at the same time, the practicability is high, the toppling phenomenon of the hurdle frames during training can be conveniently reduced, the reliability is high, meanwhile, the range of the hurdle can be conveniently adjusted according to the actual situation of a site, and the use limitation is low.

Description

technical field [0001] The invention relates to the technical field of physical education, in particular to a hurdle frame for physical education with an anti-fall function. Background technique [0002] As we all know, hurdling is a kind of sprint project with strong technical skills that crosses a specified height and number of hurdles within a certain distance. It is a kind of track and field competition. [0003] The existing hurdle frame for physical education includes two bottom bars, a cross bar is connected between the two bottom bars, a support bar is connected to the two bottom bars, and a cross bar is connected between the two support bars. At the time of training, transport multiple hurdles to the place where they need to be used, and place multiple hurdles in different places according to the training distance, and then the trainer can train. [0004] However, the above-mentioned prior art solutions still have the following defects, which require manual handlin...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned existing technical solutions still have the following defects. It needs to manually carry out multiple hurdle frames during use, which is easy to waste manpower and time, and has low practicability. The toppling phenomenon occurs due to the collision of the trainer, which easily affects the normal training situation and has low reliability. At the same time, it is not convenient to adjust the hurdle range according to the actual situation of the field when the hurdle frame is used, and the use limitation is relatively high.
