Background
Rope skipping is a very popular exercise mode, and is small and portable. But since urban residents are now mostly living in high-rise buildings, downstairs neighbors are affected if the rope is bounced at home. So the current wireless rope skipping is that the original rope skipping is changed into two short ropes. One end of the short rope is connected with the rope skipping handle, and the other end is connected with the counterweight ball. When the rope rotates and jumps, the influence on downstairs neighbors is reduced because no rope contacts the hit ground.
Chinese patent CN217187649U discloses a light-emitting ball of a cordless jump rope, in which a ferrule is directly inserted into a groove of the ball, and in order to increase the weight of the ball, a counterweight ball may be clamped in the ferrule. The connecting rope is connected with the sleeve head under the action of the stop block. When the cordless skipping rope is used, the centrifugal force of the ball body and the counter weight ball is along the separation direction of the clamping sleeve and the ball body, the pulling force of the connecting rope on the sleeve head is also along the separation direction of the clamping sleeve and the ball body, the clamping sleeve and the ball body are possibly separated under the combined action of the centrifugal force of the ball body and the counter weight ball and the pulling force of the connecting rope, and the counter weight ball falls off and flies out to hurt people.
