Hurdle frame for physical education

Abstract

The invention discloses a hurdle frame for physical education. The hurdle frame comprises a hurdle structure, a cross rod clamping structure, a cross rod height fine adjustment structure and a heightquick adjustment structure, the hurdle structure comprises a bottom supporting frame and a hurdle vertical rod, a vertical rod fixing cylinder is fixed to one end of the bottom supporting frame, a hurdle vertical rod is fixed at the top end of the vertical rod fixing cylinder; a cross rod placing frame is clamped on the outer side of the hurdle vertical rod; a cross rod clamping structure is arranged at one end of the cross rod placing frame; a height quick adjustment structure, a cross rod clamping structure and a cross rod height fine adjustment structure are arranged at one end of the crossrod placing frame; the height of the hurdle cross rod can be quickly adjusted; the hurdle structure is simple in structure and quite safe in clamping of the hurdle cross rod, when a user jumps to belower than the hurdle cross rod and touches the hurdle cross rod, the hurdle cross rod falls off immediately, accidental injury is avoided, and when the hurdle structure is used for a long time and deforms to cause inaccurate height of the cross rod placement frame, calibration can be conducted by adjusting the cross rod height fine adjustment structure.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, in particular to a hurdle frame for physical education teaching. Background technique [0002] The hurdle frame for physical education is a hurdle apparatus used for teaching and training in schools, training grounds and other places. [0003] Yet existing physical education teaching hurdle frame still has some unreasonable factors in the process of hurdle teaching training. The height of the hurdles has a gradual process, and the initial height of each student is generally different, so the height of the hurdles needs to be adjusted frequently, and the existing teaching hurdles are not fast enough to adjust; at the same time, the fixing method of the hurdles is not safe enough. When the take-off height of the students is not higher than the hurdle height, it is easy to be damaged by the hurdle; and the whole hurdle frame will be slightly deformed after long-term use, and the height will h...

When the take-off height of the students is not higher than the height of the hurdle, it is easy to be damaged by the hurdle; and the overall hurdle frame will be slightly deformed after long-term use, and the height will have a slight deviation, which is not accurate enough, and the existing hurdle frame has no adjustment method
