Title:
BALL SERVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/176573
Kind Code:
A1
Abstract:
A ball serving device (10), comprising a ball serving pipeline (12) and a limiting member (14). A pipeline inlet (122) is formed at the ball serving pipeline (12); the limiting member (14) is close to the pipeline inlet (122) and is provided on the inner wall (124) of the ball serving pipeline (12); at least two limiting points (141) are formed at the limiting member (14); the at least two limiting points (141) and the inner wall (124) form a circular limiting inlet (129); the diameter of the circular limiting inlet (129) matches the diameter of a ball body (20), so that the ball body (20) enters the pipeline inlet (122) from the circular limiting inlet (129). By providing the limiting member (14) at an inlet, the position of the ball body (20) entering the ball serving pipeline (12) is limited, and the randomness of the initial position of the ball body (20) is reduced, so that the movement trajectory of the served ball body (20) is stable, and it is helpful to accurately serve a ball having a target movement trajectory.
