[0002] Basketball production is a complex process involving multiple steps, various materials, and strict quality control. The rebound height tester plays a crucial role in basketball production. By simulating the rebound of a basketball after free fall from a certain height, the tester accurately measures the rebound height, thus evaluating the basketball's elasticity. This performance directly affects the user experience during games, such as the smoothness and accuracy of shooting and dribbling movements. As an important quality inspection tool, the rebound height tester allows for sampling inspection of each batch of basketballs produced, ensuring that the rebound performance meets design requirements. By analyzing the test data, manufacturers can promptly identify problems in the production process, such as material selection, winding density, and core hardness, thereby optimizing and improving the production process and enhancing the overall quality of the basketballs.

[0003] The problem with existing technology is that the basketball's trajectory may deviate during the bounce due to differences in materials, air pressure, or test surfaces, especially at high speeds, posing a risk of hitting the operator or people in the vicinity. Utility Model Content

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1 to 4As shown in the figure, the basketball production rebound height tester provided by this utility model includes a base 1, a lifting platform 2, a scale plate 3, and a platform 4. The lifting platform 2 is fixedly connected to the left side of the top of the base 1, the scale plate 3 is fixedly connected to the rear side of the top of the base 1, and the platform 4 is fixedly connected to the top of the base 1 and located in front of the platform 4. A lifting plate 5 is slidably connected to the surface of the lifting platform 2, and a drive box 6 is fixedly connected to the right side of the lifting plate 5. A cavity 7 is opened inside the drive box 6, and a clamping arm control structure 8 is provided inside the cavity 7.

[0019] refer to Figure 3 The clamping arm control structure 8 includes a double-headed electric cylinder 801, two moving rods 802, and two clamping arm blocks 803. The double-headed electric cylinder 801 is fixedly connected to the inside of the cavity 7. The two moving rods 802 are respectively fixedly connected to the two output ends of the double-headed electric cylinder 801, and the right side of the moving rods 802 extends out of the surface of the drive box 6. The two clamping arm blocks 803 are respectively fixedly connected to the right side of the two moving rods 802.

[0020] Using the above solution: by setting up the clamping arm control structure 8, the clamping arm block 803 can be driven to place the ball, and then the ball can be lifted to the height to be tested.

[0021] refer to Figure 3 A light rod 9 is fixedly connected inside the cavity 7, and the light rod 9 passes through the surface of two movable rods 802, and the movable rods 802 are slidably connected to the surface of the light rod 9.

[0022] By adopting the above solution, the movement of the movable rod 802 can be restricted by setting the light rod 9, and the stability of the movement of the movable rod 802 can be improved.

[0023] refer to Figure 3 The top of each of the two clamping arm blocks 803 is provided with a semi-circular groove 10, and the two semi-circular grooves 10 are arranged opposite each other.

[0024] By adopting the above solution, by setting the semi-circular groove 10, the ball to be tested can be placed on the top of the clamping arm block 803, thereby preventing the ball from rolling off.

[0025] refer to Figure 1 The top of the platform 4 is provided with a shield 11, which is made of transparent acrylic. The top of the base 1 is fixedly connected with a movable structure 12, which works in conjunction with the shield 11.

[0026] The above solution is adopted: by setting up a shield 11 and a moving structure 12, the shield 11 can shield the ball being tested, preventing the ball from leaving the test device after rebounding. Then, the moving structure 12 can drive the shield 11 to move, thereby improving its flexibility.

[0027] refer to Figure 1 and Figure 4 The movable structure 12 includes a support frame 1201, a screw 1202, a connecting block 1203, and a motor 1204. The support frame 1201 is fixedly connected to the top of the base platform 1. The screw 1202 is rotatably connected to the surface of the support frame 1201. The connecting block 1203 is threadedly connected to the surface of the screw 1202 and is fixedly connected to the surface of the shield 11. The motor 1204 is fixedly connected to the top of the base platform 1, and the output end of the motor 1204 is fixedly connected to the left side of the screw 1202. There are two movable structures 12, which are located on the front and rear sides of the shield 11, respectively.

[0028] Using the above scheme: by setting the moving structure 12, the shielding cover 11 can be moved, and then the shielding cover 11 can be used to block and restrict the test sphere.

[0029] refer to Figure 1 An extension platform 13 is fixedly connected to the top of the base platform 1, and the extension platform 13 is located on the right side of the platform 4. The top of both the platform 4 and the extension platform 13 are provided with a moving groove 14. A slider 15 is fixedly connected to the bottom of the shield 11, and the slider 15 is slidably connected to the inside of the moving groove 14.

[0030] By adopting the above solution, by setting the extension platform 13, the moving groove 14 and the slider 15, the movement of the shield 11 can be made more flexible, and the shield 11 can be prevented from being too stiff when moving.

[0031] The working principle of this utility model: In use, the basketball is placed inside the semi-circular groove 10 at the top of the two clamping arm blocks 803. Then, the lifting plate 5 is raised to the specified height by the lifting machine 2. The movement of the lifting plate 5 drives the drive box 6 to move. At this time, the basketball is at the specified height. Then, the motor 1204 is started. The motor 1204 drives the screw 1202 to rotate. When the screw 1202 rotates, it drives the threaded connecting block 1203 to move. Then, the connecting block 1203 drives the shield 11 to move closer to the basketball. Then, the shield 11 covers the basketball. At this time, the double-headed electric cylinder 801 is started. The double-headed electric cylinder 801 drives the moving rod 802 to move away from each other. Then, the moving rod 802 drives the clamping arm blocks 803 to move. At this time, due to the lack of support from the clamping arm blocks 803, the basketball falls and bounces after contacting the platform 4. The height of the basketball bounce can be recorded according to the scale plate 3.

[0032] In summary, this basketball rebound height tester, through the coordinated use of a base platform 1, a lifting platform 2, a scale plate 3, a platform 4, a lifting plate 5, a drive box 6, a cavity 7, a clamping arm control structure 8, a guide rod 9, a semi-circular groove 10, a shield 11, a moving structure 12, an extension platform 13, a moving groove 14, and a slider 15, solves the problem that basketballs may deviate from their flight trajectory during the rebound process due to differences in materials, air pressure, or the test surface, especially at high speeds, which could pose a risk of hitting the operator or surrounding personnel.
