Pit resonant pattern basketball for preventing dust, water and slipping and making method thereof

Abstract

The invention discloses a pit resonant pattern basketball for preventing dust, water and slipping. The basketball comprises a ball body, and the ball body comprises an air storage inner container, a rubber spacer layer, a winding layer, a middle blank outer skin and basketball leather in sequence from inside to outside. The winding layer is formed by winding 250D war industry nylon ropes; the basketball leather comprises a basic layer and pits, wherein the pits are evenly distributed on the basic layer; the distances between the pits and the arraying mode of the pits are identical; the polygonal basic layer defined by the adjacent pits is provided with protruding points. The basketball has the advantages of being soft and high in elasticity; the four-layer structure is adopted for the basketball, and therefore bouncing of the basketball is more sensitive and rapider; with the additionally-arranged buffering spacer layer, the basketball is soft in hand feeling and better in bouncing, micro points arranged on the protruding points of the basketball leather are embedded into fingers when the basketball is passed and handled, in this way, frictional force is increased and touch feelingis improved when the basketball is grabbed and mastered, and meanwhile the basketball is easier to master, grab and handle with the hand.

Description

technical field [0001] The invention relates to a dust-proof, waterproof and non-slip basketball with pit resonance lines and a preparation method thereof. Background technique [0002] Basketball was invented by American James Naismith in 1891. At the time, he was teaching at the YMCA International Training School in Springfield, Massachusetts. As the area is rich in peaches, children here like to play the game of throwing a ball into a peach basket. This inspired him to create a basketball game based on the characteristics of football, hockey and other ball games. [0003] Existing basketballs are divided into eight large patches with identical outer layers in shape and size. The eight stickers are also longer and have a larger arc. Many improvements have been made to this traditional basketball. The number of stickers has been increased in order to improve the grip of the basketball, the smoothness of the sticker, and enhance the appearance of the basketball. , Set bu...

AI Technical Summary

Problems solved by technology

[0004] At present, the surface of the basketball is relatively smooth, and the friction between the hand and the basketball is relatively small. Especially in the passing process, the ball is passed to another person at a certain speed, which is often caused by the small friction between the ball and the hand and the friction of the ball. If the speed is too fast, the ball will slip off. At the same time, the person who catches the ball needs more strength to catch the ball. If you exercise for a long time, it will easily make people feel
