Embodiment Construction

[0007] The present invention will be further described below in conjunction with drawings and embodiments.

[0008] As shown in Figure 1: a kind of rugby, the rugby that is made up of plastic bottle 1 and iron ball 2 is characterized in that, described rugby shell is formed by socketing of two plastic bottles 1 of the same size, and described plastic bottle 1 An iron ball 2 is built in.

[0009] Working principle: As shown in Figure 1, when the iron ball is in the middle of the hollow rugby, the center of gravity of the entire rugby is in the middle. After the ball is thrown, the rugby will start from the middle and move forward in a straight line. When the position is on the left and right sides of the hollow rugby, the center of gravity is on the left and right sides respectively. After the ball is thrown, according to the position of the iron ball, the rugby will take its center of gravity as the starting point and walk out of two curves respectively. This has It is benefi...

Abstract

The invention is concerned with the football ball that can control the movement path, consists of the plastic bottle and the iron ball, the characteristic is: the outer shell of the football ball muff couplings by two same plastic bottles that set iron ball in the plastic bottle. It is: uses the gravitational principle to change the center of gravity of the ball in order that the purpose of the user can control the movement of the ball on the ground, controls the movement direction better during the transmission process. The invention is simple structure, low cost.

Description

technical field [0001] The invention relates to a rugby ball, in particular to a rugby ball capable of controlling the movement of the rugby ball. Background technique [0002] In the prior art, the rolling of the rugby on the ground is irregular, and the movement deviation will occur during the passing process, resulting in poor ball control. Contents of the invention [0003] In order to overcome the defects in the prior art, the invention provides a rugby ball which can move in a straight line or a curve respectively. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a football, which is made up of plastic bottles and iron balls, and is characterized in that the shell of the football is formed by socketing two plastic bottles of the same size. Said plastic bottle is built with an iron ball. [0005] The beneficial effect of the invention is a kind of rugby which can be controlled. It uses the knowledge of gravity in phy...
