Description

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202211416722.6, filed with the China National Intellectual Property Administration on Nov. 14, 2022, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

BACKGROUND

During long-term volleyball teaching and training, and means and methods for cultivating and improving a setter are often scarce. A direct exercise form on a court is that the setter catches a thrown ball and passes it to a height position set in advance in the air according to tactical needs. The deviation of the height and the distance is difficult to correct without a reference. There are generally two forms of off-court auxiliary exercises. The first one is to draw a circle with the diameter of 50 cm at a corresponding height on a wall, and the setter is about 4 meters away from a wall body and catches thrown balls and passes the balls into the circle continuously. The second one is to use a basketball basket to catch the thrown balls and pass the balls to the basketball basket at the position of a free-throw line. No matter in which form, a plurality of persons are required for service to form a multi-ball cycle exercise. In addition, there is a certain gap with practical requirements.

The current passing training devices only have a function of adjusting the height of a ball hoop. The training function for passing or throwing the ball is too single, and the training at other angles, such as low throwing, cannot be completed, resulting in that the capability of a player is too simple to be effectively improved. As disclosed in CN208426611 U, a volleyball setter training device includes a telescopic support rod, a ball net, and a ball basket. A base is arranged at the bottom end of the support rod. A plurality of universal wheels are arranged at the bottom of the base. A sleeve that can move up and down along the support rod is connected to the support rod in a sleeving manner. A through hole is formed in a lower part of the sleeve. A locking screw for fixing the position of the sleeve is arranged in the through hole. A ball rim is fixed at the top end of the sleeve. The ball rim is connected to a port of the ball net. The other port of the ball net penetrates into the ball basket. In the technical solution, only the height of the ball rim can be adjusted, the function is single, and a training effect on the player is limited.

In order to solve the abovementioned problems, the present disclosure provides a volleyball passing training device to solve the problem of single function of the conventional passing training device.
