Description

Technical Field

[0001] The present invention relates to the technical field of serving training, and specifically to a serving training device for blind goalball in the Paralympic Games. Background Art

[0002] Blind goalball is a fierce sport and an essential event in the Paralympic Games. Blind goalball is usually played between two teams of three players each, with each player taking turns serving and defending. The server must ensure that the ball lands on the ground, and the defenders defend by referring to the friction sound between the ball and the ground. With the development of goalball in China, more and more disabled people have started playing goalball, and the skills of goalball require a lot of practice. The serving machine used for goalball training is an important training device.

[0003] Most of the current serving machine devices are suitable for balls with relatively light weights. For goalballs with relatively heavy weights, there are often problems such as insufficient pressure and slipping, resulting in a short serving range and failing to achieve the training effect.

[0004] In view of the above problems, the present invention provides a serving training device for blind goalball in the Paralympic Games to solve the above problems. Summary of the Invention

[0020] The second limiting ring is fixed on the extension shafts of the corresponding side connecting plates of the first motor and the second motor; and

[0021] The stamping component is arranged between the first limiting ring and the second limiting ring.

[0022] Further, preferably, the output speed of the first motor is greater than the output speed of the second motor.

[0023] Further, preferably, the stamping component includes:

[0024] There are multiple stamping cylinders, all of which are circumferentially fixed on the second limiting ring through fixing frames;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] Referring to Figures 1 to 4 , the present invention provides a technical solution: a training device for blind goalball serving in a disabled sports meeting, including:

[0039] Universal wheel 1;

[0040] Base 2, disposed on the upper end surface of the universal wheel 1;

[0041] Serving mechanism 3, disposed on one side of the upper end surface of the base 2; and

[0042] Adjusting mechanism 4, symmetrically disposed between the serving mechanism 3 and the base 2.

[0043] Wherein, the adjusting mechanism 4 can adjust the angle of the serving mechanism 3, and by changing the angle, the position of the serving point of a human can be simulated, thereby improving the training effect.

[0044] In this embodiment, the serving mechanism 3 includes:

[0045] Revolving frame 31, in a portal shape, hinged on one side of the upper end surface of the base 2;

[0046] Motor 1 32, fixed on the side surface of the revolving frame 31 away from the base 2 through a connecting plate;

[0047] Motor 2 33, fixed on the other side surface of the revolving frame 31 close to the base 2 through a connecting plate; and

[0048] Serving assemblies 34, configured to have two, respectively disposed on the output ends of the motor 1 32 and the motor 2 33.

[0049] As a preferred embodiment, the serving assembly 34 includes:

[0050] First limiting ring 341, disposed on the output ends of the motor 1 32 and the motor 2 33;

[0051] Support plates 342, provided with two groups, one group is circumferentially arranged on the first limiting ring 341, and the other group is connected by bearings on the extension shafts of the corresponding side connecting plates of the motor 1 32 and the motor 2 33;

[0052] Driving member 343, disposed on the support plate 342;

[0053] Second limiting ring 344, fixed on the extension shafts of the corresponding side connecting plates of the motor 1 32 and the motor 2 33; and

[0054] Stamping members 345, circumferentially arranged between the first limiting ring 341 and the second limiting ring 344.

[0055] It should be noted that: The motor 1 32 and the motor 2 33 drive the first limiting ring 341 connected thereto to rotate, and further drive the support plate 342 and the driving member 343 to rotate synchronously, thereby driving the gate ball to be launched from the device.

[0056] As a preferred embodiment, the output speed of the first motor 32 is greater than that of the second motor 33, which is used to give the gate ball a forward spin effect after being launched, so that the gate ball can land in time under the action of air flow, and it is convenient for the blind to distinguish the sound of the gate ball contacting the ground during training.

[0057] As a preferred embodiment, the stamping component 345 includes:

[0058] Stamping cylinders 3451, which are configured in multiple numbers and are all circumferentially fixed on the second limiting ring 344 through fixing frames;

[0059] Slide rails 3452, which are fixed inside the stamping cylinders 3451;

[0060] Sliders 3453, which are slidably arranged on the slide rails 3452;

[0061] Stamping rods 3454, which are fixed on the side of the slider 3453 close to the driving part 343; and

[0062] Connecting rods 3455, which are provided in multiple numbers corresponding to the stamping cylinders 3451. One end of the connecting rod 3455 is hinged to the side of the slider 3453 far from the driving part 343, and the other end is hinged with a rotating shaft 3456. One end of the rotating shaft 3456 is fixed to the eccentric end of the first limiting ring 341, and the other end is slidably arranged in the annular groove of the second limiting ring 344. A rotating ring is arranged in the annular groove for supporting the rotating shaft 3456.

[0063] It should be explained that: by arranging multiple stamping components 345, no matter when it is necessary to serve the ball, as long as the first motor 32 and the second motor 33 are started, the gate ball can not slip when passing through the serving assembly 34.

[0064] As a preferred embodiment, the driving part 343 includes a first rubber wheel 3431, a second rubber wheel 3432 and a telescopic rod 3433. Among them, the first rubber wheel 3431 is fixed on the support plate 342, the second rubber wheel 3432 is connected to the support plate 342 through springs at both ends, and multiple telescopic rods 3433 are arranged at multiple angles and are all arranged in the arc-shaped groove between the first rubber wheel 3431 and the second rubber wheel 3432. Among them, the spring plays a positioning role for the second rubber wheel 3432.

[0065] It should be noted that: the telescopic rods 3433 are arranged at multiple angles to evenly disperse the relatively concentrated force received by the first rubber wheel 3431 to the second rubber wheel 3432, so as to avoid the serving deviation caused by uneven force.

[0066] As a preferred embodiment, the adjusting mechanism 4 includes an adjusting rod 41 and an adjusting valve 42. One end of the adjusting rod 41 is connected to the turntable 31 by a screw nut, and the other end is hinged to the adjusting valve 42. The adjusting valve 42 is slidably disposed in the groove of the base 2.

[0067] Specifically, when the first limiting ring 341 drives the rotating shaft 3456 to rotate, while one end of the connecting rod 3455 rotates around the rotating shaft 3456, the other end slides in the slide rail 3452 through the hinged slider 3453, thereby driving the punching rod 3454 to perform a piston motion in the punching cylinder 3451. When the punching rod 3454 presses the first rubber wheel 3431, the deformed first rubber wheel 3431 will push the telescopic rod 3433 to expand outwards, thereby increasing the pressure between the second rubber wheel 3432 and the gate ball. Under the condition that the friction coefficient of the contact surface remains unchanged, it is ensured that the gate ball and the driving member 343 will not cause poor training due to slipping.

[0068] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
