Description

Volleyball training device

Technical Field

The invention relates to the technical field of physical training equipment, in particular to a volleyball training device.

Background

Volleyball sports is a sports item with a wide crowd foundation and is popular among people in all countries in the world. With the acquisition of excellent performance of the Rio Olympic Games champion and the world cup 11 of the female in China, volleyball sports are active in the public view, and are more popular with male and female players in high schools and universities at present. In the volleyball training process, the bouncing ability, the moving ability, the arm swinging ability and the like of a volleyball player are the core elements of special physical training of the player. In a real game, a volleyball player often performs attack and defense through a series of actions such as serving, putting, passing, catching and blocking, which are all integrated, and the ball is finished in a moving state. In addition, the movement ability of the volleyball players during the volleyball game is very critical, on one hand, one of the basic abilities of the volleyball players to hit the ball, and on the other hand, the ability necessary for the entire volleyball team to perform counter-attack tactics. However, in the actual volleyball training process, due to the limitation of training equipment, only a volleyball training device specially used for training the smash is provided, and the volleyball training device can only smash the fixedly clamped ball and cannot imitate the ball moving in the actual match to complete the batting action. For the training of mobility and the training of special physical ability, only real confrontation simulation exercises can be used at present. Therefore, a training device which can fit an actual combat scene, hit a naturally falling ball, change the hitting direction, control the falling speed, train high-point and low-point ball hitting, and train the moving pitching ability and special physical ability of athletes is needed.

US 8,371,964 discloses a volleyball smash training device 1, which is single use and can only be used for training the take-off of a player, but not for training the moving ability and other abilities of the player. 2. The device retrieves the part of volleyball, goes into the ball import at the top of volleyball frame, and the sportsman will retrieve the volleyball and throw the top into the ball mouth, and this action has certain degree of difficulty, inconvenient recovery volleyball. 3. The device clamps volleyballs through similar 2 arms that stretch out, and an arm is fixed, and the first ball that the other hand arm elasticity was put gets into, blocks the second ball, and after the first ball was hit out, put the second ball and get into, blocks the third ball. However, since the clips for fixing the volleyball are fixed and cannot rotate in the direction, the player cannot be trained to take the volleyball in different directions. In addition, the two arms fix the ball, and the ball is fixed instead of a naturally falling volleyball every time the player hits the volleyball, which is different from the actual game in which the moving ball is killed. 4. The device can also realize the lifting of the volleyball frame, but relies on mechanical manual lifting, and can not accurately mark the height of the volleyball frame.
