Description

Volleyball automatic training auxiliary apparatus

Technical Field

The invention relates to the technical field of volleyball training equipment, in particular to an auxiliary instrument for automatic volleyball training.

Background

Sports is a conscious, purposeful and organized social activity for improving life style and life quality, and comprises various sports projects, wherein a volleyball project is provided, the volleyball is one of ball sports projects, the volleyball is formed by using sheepskin or artificial leather as a shell and rubber as a liner, and the size of the volleyball is similar to that of a football.

As is well known, volleyball projects become popular sports in the development process of international competitive sports, school sports, national fitness and sports industry, and in volleyball sports, players or exercisers of both parties are required to hit volleyballs to obtain scores, so that the players experience competition, winning, entertainment, fitness, and spreading sports culture and harvest health, and volleyball sports requires a lot of hitting skills, such as: serve, bolster, pass, pinball, and dribble, etc., which are all key to the game; meanwhile, the ball receiving training is a training item or content which can be completed only by the cooperation of a ball serving party and a ball throwing party, the ball serving party alone cannot perform the ball serving and receiving training simultaneously, or the ball receiving party alone cannot achieve the learning and training of basic skills such as the ball cushion, the pass, the smash and the ball hanging independently, so that the athletes or the exercisers are required to frequently perform the cooperation training together, the time and the space for the athletes or the exercisers to learn, train and exercise independently are reduced, the rest and the life work and rest of the athletes or the exercisers are influenced, the training and the exercise efficiency are limited, therefore, an automatic ball serving device which can enable the athletes or the exercisers to perform the training independently is required, however, in some existing ball serving devices, balls are placed at the ball serving position by personnel, then the ball throwing device is used for serving, and the operation is troublesome, moreover, the ball throwing machine is single in device, only can send the most basic ball throwing, but cannot apply the multi-purpose ball serving skill, thereby influencing the training and exercising effects of athletes or body builders.

Meanwhile, the service training devices are placed on the other side of the training field and then perform one-to-one training with players, the existing service devices are all fixed, and the angle of the ball throwing mechanism is also fixed, so that the training effect of the training on the players is very low.

In addition, the dynamics of current service trainer can not be controlled, all is to be set for before the device is produced and dispatches from the factory, so always with same dynamics service training, can not play fine effect, when beginner trains the volleyball, just begin to use the dynamics service of setting for well just, can make the service dynamics too big simultaneously to lead to beginner to train injury etc..

Therefore, it is highly desirable to provide an automatic volleyball training device with controllable force, multiple serving modes and adjustable angle.
