Anti-falling swing and using method thereof

Technical Field

The invention relates to the technical field of swings, in particular to an anti-falling swing and a using method thereof. The invention is a divisional application of a novel anti-falling swing, which has an application date of 2018, 07, 18 and an application number of CN 201810787330.8.

Background

The swing is a sport created by minority nationalities in the north of ancient China, and a common swing is used as a game tool, a long rope is tied on a frame, a pedal plate is hung below the frame, and a person swings back and forth along with the pedal plate.

However, when people play on the swing, a person needs to push the person sitting on the swing behind, sometimes when the people play with joy, the person behind can exert great strength, so that the swing amplitude is large, the rope loses a straight state when the person sitting on the swing reaches the top end, the person sitting on the swing is in a weightless state, and the person is easy to fall off the swing without grabbing the rope, so that the result that estimation cannot be achieved is caused; in addition, in the process of swinging, other people are required to push and cooperate, and if the user pushes the toy by himself, the user is very hard to use, and the effect of easy playing cannot be achieved.

To this end, we propose a fall-prevention swing to solve the above problems.
