Automatic ball serving device for sports tennis

Abstract

The invention belongs to the field of sports equipment, particularly relates to an automatic ball serving device for sports tennis, and aims at solving the problems that the existing tennis ball serving machine is obvious in angle or position switching every time, the reaction which is pre-judged in advance is provided for training players, the training of a real scene is difficult to achieve, and the training cannot be carried out under the condition that the service position is unknown. According to the technical scheme, the ball serving device comprises two moving seats, frame plates are fixedly installed on the tops of the two moving seats, the same ball serving plate is fixedly installed on the sides, close to each other, of the two frame plates, a plurality of ball serving grooves are formed in one side of the ball serving plate, a controller is fixedly installed on the other side of the ball serving plate, and rotating columns are rotationally installed in the multiple ball serving grooves. The tennis ball serving machine is reasonable in structure and convenient to operate, the tennis ball serving machine is hidden when the angle or the serving position is switched, pre-judgment can be prevented from being provided for a trainer, training in a real scene can be achieved, and reaction training can be conducted under the condition that the serving position is not known.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an automatic ball-serving device for sports tennis. Background technique [0002] Tennis is one of the ball games. The effective tennis field is a rectangle with a length of 23.77 meters. The width of the singles field is 8.23 ​​meters, and the width of the doubles field is 10.97 meters. There is a net in the middle. Hitting the ball with a tennis racket, as a confrontational sport, will be very awkward when there is only one person, and the emergence of tennis machines has largely solved similar problems; [0003] However, the existing tennis ball machines, such as CN212395805U and CN212214548U, are more obvious when switching angles or positions each time, giving the training players a pre-judged response, which is difficult to achieve the training of the real scene, and it is impossible to train without knowing the position of the ball. .
