Jumping stand for physical education

Abstract

The invention discloses a jumping stand for physical education. The jumping stand for physical education comprises a base, wherein a first cavity is formed in the base, two rotary shafts are vertically arranged in the first cavity, two square limiting blocks are arranged on the upper surface of the base, a rotary mechanism is arranged on the side wall of the base, the end, extending the outside, of a fixing shaft is connected with the rotary mechanism, and a limiting mechanism for limiting rotation of the rotary mechanism is arranged on the side wall of the base. Two fixing seats are arrangedon the upper end face of the base, clamping mechanisms are arranged between the fixing seat and the base, round grooves are formed in the lower end faces of the fixing seats, fixing blocks are arranged in the round grooves, square limiting grooves matched with square limiting blocks are formed in the lower end faces of the fixing blocks, fixing rods are arranged on the upper end faces of the fixing seats, and a transverse supporting rod is fixedly connected to the outer side wall of an annular part. The jumping stand for physical education is reasonable in structure, facilitates adjustment ofcross rod height during jumping, meanwhile is convenient to dismount and change and can save space.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a high jump frame for physical education. Background technique [0002] High jump, one of the jumping events in track and field sports, consists of rhythmic approach, one-foot take-off, vacating the pole and floor lamp as the east. Promoting the growth of bones and muscles is of great significance for improving physical fitness. The equipment used in high jump is mainly the high jump frame. The traditional high jump frame is composed of two side bars, an integral cross bar and the legs of the cross bar. The traditional adjustment of the height of the bar is very complicated. There may be many students in the process of physical education teaching, which is a waste of time. , the need for a high jump frame that can quickly adjust the height of the cross bar. Simultaneously, the overall structure of the high jump frame is relatively large, and it takes up a large space ...

AI Technical Summary

Problems solved by technology

The equipment used in high jump is mainly the high jump frame. The traditional high jump frame is composed of two side bars, an integral cross bar and the legs of the cross bar. The traditional adjustment of the height of the bar is very complicated. There may be many students in the process of physical education teaching, which is a waste of time. , the need for a high jump frame that can quickly adjust the height of the cross bar

At the same time, the overall structure of the high jump frame is large, and it takes up a lot of space when not in use, and it is troublesome to replace the side pole when it is damaged.
