Momentum swing

Abstract

The invention relates to a momentum swing which is composed of swing ropes (4), a swing board (5), a support, a rail car (1), a sandpit, sand and a telescopic board. The sandpit is formed in the ground below the swing board (5) and filled with the sand, and safety is remarkably improved compared with that of a traditional swing. The upper ends of the swing ropes (4) move along with the rail car (1), the rail car (1) has multiple motion modes, and the swing has more enjoyment and thrill and the larger exercise amount compared with the traditional swing and has relatively large attraction to middle-aged and young people. The momentum swing contains rich physical content and shows colorful physical models, and in motion, the swing participates in the complex physical process, stimulates scientific interest, improves perceptual knowledge of physical phenomena, lays a foundation for sublimating perceptual knowledge into rational cognition and creates conditions for improving the scientific quality of citizens.

Description

technical field [0001] The invention relates to a momentum swing, in particular to a momentum swing that is safe, interesting and stimulating, has a greater amount of exercise, and contains more physical knowledge. Background technique [0002] The traditional swing has a good effect on enhancing muscle strength, developing body coordination, and cultivating bravery, but it has some shortcomings. [0003] First, it is unsafe, and people fall from the swing board to the ground, which will have serious consequences. The method adopted now is to shorten the swing rope. With such a change, the fun and excitement are greatly reduced, not only the danger is not eliminated, but the young and middle-aged people are not interested in it, and the players are almost extinct. [0004] Second, there has been no innovation and change for a long time, and the interest is not strong; it always swings back and forth, the movement is monotonous, and the stimulation is not strong. Young and...
