Problems solved by technology
[0002] In the current physical education classes of junior high school and high school, there will be volleyball exercises. Generally, volleyball jumping is practiced and taught. Especially in junior high school, most of the courses are to practice volleyball jumping. The space is limited. In most cases, there are many classes sharing a playground. The location of each class is relatively fixed, and the space for each person is relatively small. In the beginning, the wrong posture often caused the ball to deviate. In the actual teaching, most of the time is picking up the ball instead of practicing jumping the ball. Usually, barbed wire is set up around the court to restrict the ball from flying around. Smaller doesn't keep the ball in a smaller range

Embodiment
[0030] Embodiment: a kind of volleyball training device, comprises blower fan 1 and support 2, and described blower fan 1 is installed on the support 2, and described blower fan 1 forms plane air curtain upwards, and a plurality of blower fans 1 are arranged in a ring to form continuous air curtain continuously, The air curtain formed by the air outlet 3 of the fan 1 faces upwards obliquely inside the ring. During the practice of volleyball, the force on the volleyball in the air is relatively stable, only by gravity and air resistance. The airflow can effectively change the flight trajectory of the volleyball. In the process of juggling the ball, the flying volleyball can be blown to the center of the ring through the wind curtain,
[0031] The fan 1 is used to blow out the air curtain, the fan 1 is a cross-flow fan 1, the rotation axis of the cross-flow fan 1 is arranged horizontally, the top of the fan 1 is provided with an air outlet 3, and the side of the fan 1 is close to...

The invention discloses a volleyball training device, and mainly relates to the field of volleyball training assistant tools. The volleyball training device comprises fans and a support, the fans arefixed to the support, the fans are used for blowing an air curtain out, the fans face upwards to form a plane air curtain, the fans are continuously arranged to form a ring, and the air curtain formedat the air outlets of the fans is towards the oblique upper side in the ring. The air outlets are formed in the tops of the fans, air inlets are formed in the portions, close to the bottoms, on the lateral sides of the fans, the two ends, in the length directions, of the fans are outwards provided with connecting sleeves in the length directions respectively, and the top of the support is provided with connecting pins. The fans are connected with the support through the cooperation of the connecting sleeves and the connecting pins, the air outlets of the fans are provided with guide plates which are used for changing the air supply direction of the fans, and the guide plates change the angle between the air outlet direction and the ground by changing the angles of the guide plates. The volleyball training device has the advantages that the moving directions of volleyballs in air are limited through the air curtain so as to make the volleyballs within a certain range.
