Description

Technical Field

[0001] The present invention relates to the technical field of sports training auxiliary equipment, and particularly to a catching training device. Background Art

[0002] Basketball is a physical confrontation sport centered around the hands and is the second most popular sport in the world after football. Basketball is a very popular sport, and the purpose of basketball is to throw the basketball into the basket, and there will be a sense of achievement when the basketball is sent into the basket. Professional basketball players will conduct various trainings during the rest of the game in order to improve their abilities on the court.

[0003] The passing and catching technique is a method of purposefully passing the ball between players in a basketball game. It connects various techniques and players into one entity and is the most frequently used technique in a basketball game. The quality of passing and catching directly affects the quality of tactics. In the game, in order to create favorable scoring opportunities for teammates, players need to organize various tactical combinations. However, no matter how ingeniously these combinations are designed, if the passing and catching cannot be carried out in a timely manner in the end, they will be useless.

[0004] In basketball catching, various interference factors are often encountered, such as dynamic interference from opposing players on the catching route, and changes in the direction, trajectory, and speed of the basketball in the air during catching due to obstacles. These are all the contents that need to be focused on and strengthened during basketball training.

[0005] Currently, the devices for basketball catching training basically use some simple basketball serving mechanisms to send out basketballs for the trainees to catch and train, and cannot effectively train for the above-mentioned interference factors. Summary of the Invention

[0006] An embodiment of the present invention provides a catching training device, which can solve the problem in the prior art that the basketball catching training device cannot simulate the dynamic interference of opposing players on the catching route during the basketball catching process, and the problems of changes in direction, trajectory, and speed of the basketball in the air during catching due to obstacles, which are not conducive to catching interference factors.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: A catching training device, a base, further comprising:

[0008] A serving machine, the serving machine is rotatably connected to the upper end of the base, the serving machine includes a serving tube for sending out basketballs, and a goal inlet for sending the basketballs into the serving tube is arranged on the serving tube;

[0009] A first driving part, the first driving part is arranged on the base, and the outer output end of the first driving part is fixedly connected to the bottom of the serving machine;

[0010] An arc-shaped rack, wherein the arc-shaped rack is arranged on one side of the ball feeder, and the central axis of the arc-shaped rack coincides with the center line of the output shaft of the driving part;

[0011] An interference component, which is used to change the running trajectory of the basketball colliding with it in the air;

[0012] The interference component includes a long rod horizontally arranged on the ball feeder. An outer shell is arranged at the end of the long rod. A first gear meshing with the arc-shaped rack is rotatably connected to the lower part inside the outer shell. A driving pin is adjustably arranged on the first gear. A connecting rod is rotatably connected to the driving pin. An interference plate is vertically slidably connected to the upper end of the outer shell, and the lower end of the interference plate is rotatably connected to the connecting rod.

[0013] Preferably, the interference component further includes two swing arms rotatably connected to the upper part of the interference plate. Side interference plates are arranged at the ends of the swing arms. A double-row rack is vertically slidably connected to the inside of the interference plate. Second gears meshing with both sides of the double-row rack are coaxially arranged with the two side interference plates respectively. A single-row rack extending into the inside of the interference plate is arranged inside the outer shell. An incomplete gear adapted to the single-row rack is rotatably connected to the inside of the interference plate. A winding wheel is coaxially arranged with the incomplete gear. A pull rope with one end fixedly connected to the double-row rack is wound around the winding wheel. A first elastic member is arranged between the upper end of the double-row rack and the inner top wall of the interference plate.

[0014] Specifically, during the lifting process of the interference plate, the incomplete gear will be driven to move vertically relative to the single-row rack. The up-and-down moving incomplete gear rotates under the meshing action with the single-row rack, and when disengaged from the meshing, it resets under the pulling force of the first elastic member, causing the winding wheel to make a reciprocating rotational motion. The double-row rack is driven to make a reciprocating lifting motion through the pull rope. The reciprocating lifting double-row rack drives the swing arms to swing reciprocally through the second gears, simulating the dynamic interference actions of the opponent player's arms on the receiving route of the ball, increasing the uncertainty of the basketball's movement trajectory, and training the basketball player's receiving ability.

[0015] Preferably, the swing arm includes a first swing arm, a second swing arm, a universal ball head and a second elastic member. The first swing arm is coaxially arranged with the second gear.

[0020] Specifically, during the receiving training of the basketball player, the second driving part is started, the second driving part drives the trapezoidal lead screw to rotate clockwise or counterclockwise. Under the guiding action of the guiding groove, the trapezoidal lead screw drives the lead screw nut to move radially on the first gear, the lead screw nut drives the driving pin to move radially on the first gear, randomly adjusting the position of the driving pin, and further making the stroke of the interference plate in dynamic change, simulating the bouncing action of the opponent player on the receiving route, and the simulated bouncing height is in dynamic change, further increasing the uncertainty of the basketball movement trajectory, and training the receiving ability of the basketball player.

[0037] During specific use, the first driving part 4 drives the ball tube 2 to reciprocate within the range of the radian angle formed by the arc-shaped rack 6 to adjust the serving direction. During the rotation of the ball tube 2, the outer housing 7 is driven to reciprocate on the arc-shaped rack 6 through the long rod 5. The first gear 8 meshing with the arc-shaped rack 6 rotates forward or backward. The rotating first gear 8 drives the driving pin 9 to rotate in the same direction around the center of the first gear 8. The driving pin 9 drives the interference plate 11 to reciprocate up and down through the connecting rod 10, simulating the bounce interference of the opponent player on the receiving route. The basketball player moves and catches the ball in the outer area of the arc-shaped rack 6.

[0038] In order to achieve the purpose of dynamically interfering with the opponent player on the receiving route during the simulation of the basketball receiving process, preferably, the interference component further includes two swing arms rotatably connected to the upper part of the interference plate 11.
