Description

Technical Field

[0001] The utility model belongs to the technical field of volleyball serving training, and particularly relates to a volleyball serving auxiliary training device. Background Technique

[0002] Volleyball is a sport completed through the cooperation of multiple people. During training, at least one person serves the ball to cooperate with the athletes for training. To liberate the server, a volleyball serving machine is designed to assist the athletes in training.

[0003] Volleyball launchers are generally divided into semi-automatic and fully automatic ones. When a semi-automatic volleyball launcher serves the ball, generally, a person manually places the volleyball at a designated position, and then the volleyball launcher will send the volleyball out. However, existing semi-automatic volleyball launchers generally lift the launcher to a relatively high position, and the machine generally has a standing platform. Due to individual differences among people, if the server is of relatively short height, they will be farther away from the launcher, and the consumption after serving the ball for a long time is greater than that of normal serving, thereby affecting the serving efficiency. For this reason, we propose a volleyball serving auxiliary training device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a volleyball serving auxiliary training device. By setting a support component, specifically, the two threaded directions of the bidirectional threaded rod are opposite, so the moving directions of the two moving plates are also opposite. As the two moving plates move, they further drive the movement of the connecting rods. Through precise cooperation and linkage among the four connecting rods, the standing plate can be smoothly raised or lowered. To control the rotation direction of the second motor to ensure that the standing plate can accurately move to a suitable height, people of different heights can be adjusted to a suitable height, better send the volleyball to the serving device, and improve the serving efficiency, solving the problem that existing semi-automatic volleyball launchers generally lift the launcher to a relatively high position, and the machine generally has a standing platform. Due to individual differences among people, if the server is of relatively short height, they will be farther away from the launcher, and the consumption after serving the ball for a long time is greater than that of normal serving, thereby affecting the serving efficiency.

After taking a position on the standing board 134, one can start to prepare for adjusting the standing height. It is necessary to start the second motor 135. After receiving the start signal, the second motor 135 starts to drive the bidirectional threaded rod 351 to rotate. The design of the bidirectional threaded rod 351 enables it to drive two moving plates 137 to move simultaneously during rotation. Since the two thread directions of the bidirectional threaded rod 351 are opposite, the moving directions of the two moving plates 137 are also opposite. With the movement of the two moving plates 137, they further drive the movement of the connecting rods 133. Through precise cooperation and linkage among the four connecting rods 133, the standing board 134 can be smoothly raised or lowered. It is necessary to control the rotation direction of the second motor 135 to ensure that the standing board 134 can accurately move to a suitable height. After the standing board 134 moves to a suitable height, it starts to prepare for adjusting the serving direction. To achieve this goal, it is necessary to start the first motor 213. After receiving the start signal, the first motor 213 starts to drive the limit ring 212 to rotate. The rotation of the limit ring 212 further drives the rotation of the slide rail 211. The rotation of the slide rail 211 is a key step in adjusting the serving direction. By precisely controlling the rotation speed and rotation angle of the first motor 213, the slide rail 211 can be rotated to the required angle, thereby changing the serving direction.
