Abstract
Description
Technical Field
[0001] This utility model relates to the field of tennis ball production technology, specifically to an elasticity testing device for tennis ball production. Background Technology
[0002] The elasticity of a tennis ball directly determines its rebound height and speed after landing. The International Tennis Federation (ITF) stipulates that when a standard tennis ball is dropped freely from a height of 254 cm onto a concrete surface, the rebound height should be within the range of 135-147 cm. Publication number CN217466505U discloses an elasticity testing device for tennis ball production, relating to the field of tennis ball production technology. It includes a base, with a support plate mounted on the top of the base via a testing platform mechanism. A fixed frame is mounted on the top of the base, and a movable frame is mounted on the testing platform mechanism. A hydraulic cylinder runs through the support plate, and a pressure plate is mounted at the bottom of the piston rod of the hydraulic cylinder. The pressure plate is movably connected to the testing platform mechanism. While this device has significant advantages, during use, workers need to manually place the tennis balls into the fixed frame. Repeating this action for a long time can easily lead to distraction and increase the risk of misoperation, such as missing balls.
[0003] Therefore, we propose an elasticity testing device for tennis ball production. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example
[0019] Please see Figures 1-3 The diagram illustrates an elasticity testing device for tennis ball production, comprising a base 1, with multiple support columns 2 fixedly connected to the base 1. Each support column 2 is fitted with a spring 3, and each support column 2 is slidably connected to a sliding plate 4. A pressure plate 5 is located above the sliding plate 4, and a fixed base 6 is located below the sliding plate 4. A telescopic rod 7 is fixedly connected to the sliding plate 4, and a linkage rod 8 is located inside the telescopic rod 7. The linkage rod 8 is slidably connected to the interior of an L-shaped connecting plate 9 used to obstruct and guide the tennis ball. A second spring 10 is located below the L-shaped connecting plate 9. A guide base 11 is located on one side of the fixed base 6, and a storage box 12 is located on one side of the guide base 11 for storing the tennis ball. The top of the storage box 12 is equipped with a motor 13, and the inside of the storage box 12 is equipped with guide vanes 14. This utility model has a linkage rod inside the fixed base, a telescopic rod and a sliding plate of the linkage rod, and the linkage rod is slidably connected to an L-shaped connecting plate. The L-shaped connecting plate tightly presses against the top of the spring. A guide base is provided on one side of the fixed base, and the guide base is connected to the storage box. The motor equipped on the top of the storage box drives the internal guide vanes, thereby eliminating the need for manual placement, avoiding the problem of distraction caused by long-term repetitive labor, reducing direct human contact, and reducing the risk of accidental injury due to operational errors.
[0020] Furthermore, a hydraulic cylinder 15 is provided on the top of the base 1. The extension end of the hydraulic cylinder 15 is fixedly connected to the pressure plate 5. The hydraulic cylinder 15 is fixedly connected to the top of the base 1. By driving the pressure plate through the hydraulic cylinder, the smoothness and linearity of the pressure plate movement are achieved, thereby improving the overall stability. At the same time, the hydraulic cylinder has lower maintenance costs and a lower failure rate, which helps to reduce the overall operating cost of the device.
[0021] Furthermore, the fixed base 6 is equipped with a locking block 601 inside. The locking block 601 engages with the second spring 10. Through the engagement of the locking block and the second spring, the L-shaped connecting plate is securely fixed inside the fixed base. At the same time, it can cooperate with the fixing and releasing action of the sliding plate to realize the automatic loading, fixing and releasing of the tennis ball.
[0022] Furthermore, the fixed base 6 is equipped with an L-shaped connecting plate 9 inside. The L-shaped connecting plate 9 is rotatably connected to the inside of the fixed base 6. The L-shaped connecting plate 9 consists of an extension plate 901 and a hollow plate 902. The linkage rod 8 is slidably connected to the inside of the hollow plate 902. The L-shaped connecting plate is composed of an extension plate and a hollow plate, and it is connected to the inside of the fixed base by a rotatable connection. This makes the movement trajectory of the L-shaped connecting plate inside the fixed base more reasonable. When the hydraulic cylinder drives the pressure plate to fix or release the tennis ball, the L-shaped connecting plate can drive the slid plate to move along a predetermined trajectory to ensure the stability of the tennis ball movement.
[0023] Furthermore, the fixed base 6 is provided with a limiting block 602, and a linkage rod 8 is provided on the inner side of the limiting block 602. The limiting block restricts the movement range of the linkage rod to prevent it from exceeding the preset safety area during movement. When the linkage rod moves under the drive of the sliding plate or L-shaped connecting plate, the limiting block can effectively block its excessive movement, thereby avoiding collision or interference between the linkage rod and other components, and providing additional safety protection.
[0024] Furthermore, the fixed base 6 has an inclined surface near the extension plate 901. The extension plate 901 tightly presses against the second spring 10. The inclined surface design of the fixed base allows the tennis ball to flow evenly along the inclined surface. At the same time, the elastic support of the second spring can effectively make the extension plate automatically reset, ensuring the stability of the extension plate during the movement and avoiding problems such as insecure fixation caused by loosening or shaking.
[0025] In this solution, the workflow is as follows: After the elasticity test is completed, the hydraulic cylinder drives the pressure plate to move upward, releasing the tennis ball from its fixation. At this time, the sliding plate moves upward under the action of the spring force, thereby driving the telescopic rod to move upward. The telescopic rod then drives the linkage rod to move, and the linkage rod drives the L-shaped connecting plate to rotate inside the fixed base. At this time, one end of the L-shaped connecting plate will tightly press against the second spring, and at the same time, it will drive the tennis ball inside the fixed base to move to one side. When the tennis ball leaves the fixed base, the motor on the top of the storage box starts, driving the guide vane to rotate, moving the tennis ball with the test result out of the storage box, preparing for the test of the next tennis ball.
