Description

Technical Field

[0001] The utility model belongs to the technical field of volleyball training devices, in particular to a volleyball training device for physical education teaching. Background Art

[0002] Sports volleyball teaching refers to the teaching activities of volleyball in schools or other educational institutions. Volleyball is a popular team sport, and teaching can help students improve their physical fitness, cultivate team spirit and master volleyball skills.

[0003] In a Chinese patent with publication number CN213789881U, a volleyball training device for physical education is mentioned. In this utility model, athletes loosen bolts according to their own training conditions to facilitate the movement of the positioning plate, thereby driving the bottom sliding rod to slide in the gap formed between the inner rectangular frames. After the adjustment is completed, the bolt thread is installed in the threaded hole opposite the position of the inner rectangular frame. After training for a period of time, the position of the detection piece can be adjusted again to facilitate the practice of multiple positions in the venue. At the same time, the strength and accuracy of the volleyball hit by the athlete can be detected. According to the training situation, the position of the detection piece can be adjusted and fixed in the gap between the outer rectangular frame and the inner rectangular frame to ensure the convenience of the detection piece to move, thereby facilitating training.

[0004] However, the utility model requires manual adjustment of the position of the detection piece, which is inconvenient to adjust. Physical education teaching generally has limited time and a large number of students. Multiple adjustments require a waste of physical education teaching time, which reduces the efficiency of volleyball training and is likely to cause some students to be unable to obtain multiple volleyball training. In addition, the detection piece is static during training, which is not conducive to improving students' flexibility and hit rate when playing volleyball. Utility Model Content

[0034] As can be seen from the above, when students are doing volleyball training, the teacher can use the PLC controller 204 to randomly start one of the two 205 drive motors or both of them at the same time according to the label 202, drive the threaded rod 206 to rotate, and the threaded ring inside the transverse plate 207 engages with the threaded rod 206, thereby driving the transverse plate 207 to move laterally, and then drive the track 208 to move laterally, and further drive the receiving plate 213 and the pressure sensor 214 to move laterally. The corresponding transmission component 210 can be started by the number 215 to rotate the driving wheel 211, and further make the support frame 209 and the driven wheel 212 move longitudinally on the outer surface of the track 208. Therefore, the physical education teacher can use the PLC controller 204 to make the receiving plate 213 and the pressure sensor 214 move laterally or longitudinally, or move them laterally and longitudinally at the same time. The student first receives the volleyball sent by the volleyball server, and then hits it to the moving receiving plate 213 and the pressure sensor 214 through the volleyball net 104. Sensor 214, after the volleyball hits the target receiving plate 213 and the pressure sensor 214, the pressure sensor 214 monitors the pressure and transmits it to the PLC controller 204, and the physical education teacher determines whether it is a hit. By setting the movable mechanism 200, firstly, in the physical education class, students can choose static or dynamic training. Through dynamic training, the receiving plate 213 is kept moving, and the students need to hit the target receiving plate 213, thereby improving the training effect and improving the flexibility and hit rate of the students' volleyball training. Secondly, the physical education teacher can randomly control the movement of the receiving plate 213 through the PLC controller 204, allowing the students to hit the receiving plate 213 with the target number 215, thereby effectively testing the effect of the students' volleyball training. Finally, the position of the receiving plate 213 is convenient and quick to adjust, and no manual adjustment is required, which can improve the use efficiency of the device. It is particularly suitable for physical education classes with many students and limited time, which can enable more students to get the opportunity to train in volleyball and improve teaching efficiency.
