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.

- 3. In the present disclosure, the sliding rail is arranged on the coaming. A second sliding block is arranged on the sliding rail. A pair of clamping plates with the same spacing as the outside diameter of the fixing sleeve are arranged on the second sliding block. The third through holes are formed in the second sliding block located on the outer side of the adjacent clamping plate. A plurality of fourth through holes are formed in the sliding rails. The spacing between adjacent third through holes is the same as that between adjacent fourth through holes. The bolts penetrate through the third through holes and the fourth through holes to fix the sliding blocks. The fixing sleeve is clamped between the adjacent clamping plates. After a long-time exercise, if a ball falling position is not adjusted, the balls will be accumulated at a certain position in the collection box to block the bottom of the collection net, so that the balls cannot fall into the collection box smoothly. Therefore, the adjustment of the position of the fixing position promotes the adjustment of the position of the ball hoop and the position of the collection net, which avoids the problem that the balls are accumulated at the same position in the collection box.

The angle adjustment mechanism includes a connecting piece connected to the ball hoop, and a first connecting rod and a second connecting rod respectively hinged to the connecting piece. A sliding device which can slide or fix on the second connecting rod is arranged on the second connecting rod. The first connecting rod is hinged to the sliding device. Connecting lines of the hinge points between the first connecting rod and the connecting piece and between the second connecting rod and the connecting piece and the hinge point between the first connecting rod and the sliding device form a triangle. According to the present disclosure, the hinged first connecting rod, second connecting rod, and connecting piece, and the sliding device are arranged, and the sliding device moves up and down on the second connecting rod, so as to drive the first connecting rod to move downward. Due to the hinge of the first connecting rod and the connecting piece, the connecting piece will rotate around the hinge point of the connecting piece and the second connecting rod, so as to drive the ball hoop arranged on the connecting piece to rotate around the hinge point, and then to adjust the opening direction of the ball hoop, thereby achieving the objective of adjusting the angle of the ball hoop. Therefore, a practitioner can practice passing balls at different angles to the ball hoops at different angles. The overall adjustment process is simple and convenient, and the improvement of the training efficiency is facilitated.
Referring to FIG. 1, the sliding device includes a first sliding block and a positioning pin which are arranged on the second connecting rod in a sleeving manner and can slide. A first through hole is formed in the first sliding block. The positioning pin is inserted into the first through hole for fixing the first sliding block. After the angle of the ball hoop is adjusted in place, the first sliding block is fixed by screwing the positioning pin in the first through and pressing against the second connecting rod.
Referring to FIG. 1, the connecting piece is an L-shaped rod with an included angle being an acute angle. One side is connected to the ball hoop; and the other side is hinged to each of the first connecting rod and the second connecting rod through hinges. Further, at least two strengthening rods are arranged in the included angle of the connecting piece, which are used for strengthening the connecting strength between the connecting piece and the ball hoop.
