Volleyball launching device for physical training

Abstract

The invention relates to the field of sports training aid equipment, and discloses a volleyball launching device for physical training. The device comprises a base, two supporting plates are fixedly installed at one side of the top of the base, the top ends of the two supporting plates are fixedly sleeved with one positioning shaft, the middle of the positioning shaft is movably sleeved with a rotating frame, and a limiting shaft located at one side of the supporting plate is fixedly installed at the front face of the rotating frame. According to the volleyball launching device for physical training, a movable block is moved to drive a driven plate to move, a positioning clamping piece makes contact with a sliding rod through a rotating screw, and therefore the movable block is fixed, andthen the stretched length of a compressed spring is adjusted; accordingly, volleyballs are hit due to the elastic force effect of the compressed spring, the volleyball launching speed is adjustable, and the phenomena that due to the fact that a common launching device for assisting athletes in training can only launch balls and cannot adjust the volleyball launching speed, each volleyball launching speed is identical, and the athlete training effect is not high are avoided.

Description

technical field [0001] The invention relates to the field of auxiliary sports training equipment, in particular to a volleyball ejection device for sports training. Background technique [0002] Volleyball is one of the ball sports. It is called the three major balls together with football and basketball. In the daily training of professional athletes, it is often necessary to practice catching the ball alone, respond quickly to the ball from all directions, and use the correct way of retaliation. [0003] However, the common serving equipment that assists athletes in training can only launch the ball, and cannot adjust the speed of launching the ball, so that the speed of each serving is the same, resulting in low training effect for athletes, and the common serving equipment cannot control the angle of the ball, and cannot Bring substantive improvement to athlete, thereby can not satisfy the training demand of athlete. Contents of the invention [0004] (1) Solved tech...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a volleyball ejection device for sports training, which has the advantages of being convenient to control the serving speed and the height angle of the serving, and solves the problem that the common serving equipment that assists athletes in training can only launch the ball and cannot Adjust the speed of launching the ball so that the speed of each serving is the same, resulting in a low training effect for the athletes, and the common serving equipment cannot control the angle of the ball, which cannot bring substantial improvement to the athletes, thus failing to meet the training needs of the athletes The problem
