Description

Technical Field

[0001] The invention belongs to the field of badminton racket deflection test, and in particular relates to a badminton racket deflection test device. Background Art

[0002] In the process of badminton racket research and development and quality control, it is very important to accurately test the deflection of the badminton racket. The deflection test can not only reflect the elasticity and rigidity of the badminton racket, but also evaluate its performance in actual use. However, traditional testing devices have some limitations in clamping and adjusting the shape of the badminton racket. These devices can usually only be tested in a single plane or vertical placement, and cannot flexibly adjust the test angle and position of the racket, which limits the comprehensiveness and accuracy of the test. This limitation affects the accuracy of the badminton racket test. Specifically, a single plane or vertical placement cannot fully simulate the various force conditions of the badminton racket in actual use. In real sports, the badminton racket will be subjected to forces from different directions and angles, resulting in complex bending and deformation of the racket frame. The single test method of the traditional testing device cannot fully reflect this complex mechanical property, resulting in a deviation between the test results and the actual use.

[0003] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See also Figure 1-6As shown, in this embodiment, a badminton racket deflection test device is provided, comprising a platform 1, a clamping device is fixedly connected at the first edge above the platform 1, a height gauge assembly is connected at the second edge above the platform 1, and the clamping device comprises a connecting frame 2 located at the first edge above the platform 1, a racket handle upper clamp 3 is installed above the connecting frame 2, a support frame 4 is fixedly connected above the connecting frame 2, a telescopic cylinder 5 is fixedly connected above the support frame 4, a slide plate 6 is fixedly connected to the output end of the telescopic cylinder 5 through the support frame 4, and a racket handle lower clamp 7 adapted to the racket handle upper clamp 3 is fixedly connected below the slide plate 6. When the deflection of the badminton racket needs to be tested, the position of the badminton racket is first fixed by the handle upper clamp and the handle lower clamp. The specific operation is to place the handle part of the badminton racket in the handle upper clamp, and then use the handle lower clamp to clamp it firmly to ensure that the racket handle will not be displaced during the test. After fixing the badminton racket, select the end of the racket frame away from the handle, and measure and mark the position at two-thirds of the distance from the handle.

[0022] Next, hang flanges of different weights at the marked positions. The weight of the flanges can be gradually increased from light to heavy to observe the change in the deflection of the badminton racket under different loads. After each hanging of the flanges, record the degree of deformation of the racket frame. This can be accurately measured using the numerical display 20 on the height gauge assembly. The height gauge assembly can display the displacement of the racket frame under the action of flanges of different weights, thereby accurately reflecting the change in the deflection of the badminton racket.

[0023] Based on these data, the bending degree of the racket frame under different loads is analyzed to determine its deflection performance. By comparing the deformation under different weights, the rigidity and elasticity characteristics of the badminton racket can be evaluated, and then its performance in actual use can be understood. These data can not only help determine the quality of badminton rackets, but also provide an important basis for improving and optimizing the design of badminton rackets.

[0024] In this embodiment, a notch 8 adapted to a badminton racket is provided between the upper clamp of the handle and the lower clamp of the handle, an arc plate 9 is rotatably connected at the inner wall edge of the notch 8, a connecting block 11 is fixedly connected to the first side of the arc plate 9, a plurality of friction protrusions 10 are fixedly connected to the inner wall of the arc plate 9, an arc groove for sliding the connecting block 11 is provided on the inner wall of the notch 8, and a spring 12 is connected between the arc groove and the connecting block 11. By arranging the arc groove and the spring 12 between the upper clamp of the handle and the lower clamp of the handle, it can be ensured that the opening of the arc plate 9 always remains relative. This means that no matter how much force is applied from the outside, the two arc plates 9 will automatically adjust under the action of the spring 12 to maintain a relatively constant clamping force, thereby ensuring that the badminton racket will not slide or deflect during the clamping process. This design can adapt to badminton racket handles of different thicknesses and shapes, making the device more widely applicable. In addition, a plurality of friction protrusions 10 are provided on the inner wall of the arc plate 9, which can increase the friction between the arc plate 9 and the handle of the badminton racket. When the arc plate 9 clamps the handle of the badminton racket, these friction protrusions 10 will be embedded in the handle surface, providing additional stability and preventing the handle from slipping or loosening during testing or adjustment.

[0025] In this embodiment, a connecting block 11 is connected to the lower part of the arc plate 9, and a slide groove 13 adapted to the connecting block 11 is provided on the upper part of the arc plate 9. After the upper clamp and the lower clamp are assembled, the connecting block 11 is inserted into the inner part of the slide groove 13. By arranging the connecting block 11 under the arc plate 9, when one arc plate 9 rotates, the other arc plate 9 can be driven to rotate together. This design ensures that the two arc plates 9 move synchronously during operation, thereby maintaining the same clamping force on the badminton racket. Specifically, when the position of the badminton racket needs to be adjusted, only force needs to be applied to rotate one arc plate 9, and the other arc plate 9 will automatically rotate with the action of the connecting block 11.

[0026] The advantage of this synchronous rotation mechanism is that it simplifies the operation steps. It is not necessary to adjust the two curved plates 9 separately. The position of the badminton racket can be adjusted by adjusting only one curved plate 9. This not only improves work efficiency, but also reduces the error caused by multiple adjustments. Through position changes, the deflection of the badminton racket can be tested from multiple angles. This helps to fully evaluate the elasticity and durability of the racket and ensure that it performs well under different usage conditions.

[0027] In this embodiment, one side of the two arc plates 9 is connected to an arc ring 14, and the outer wall of the arc ring 14 is provided with gear teeth 15. A mounting groove is provided on one side of the lower fixture, and a self-locking motor is installed inside the mounting groove. The output end of the self-locking motor is fixedly connected to a gear 16 that meshes with the gear teeth 15. The setting of the self-locking motor can facilitate the subsequent rotation of the gear 16. The self-locking motor has the ability to maintain the current position after power failure, which means that once adjusted to the desired position, the motor will remain stable and will not change position due to external force or vibration. This provides a reliable guarantee for the test process and avoids test errors caused by position changes.

[0028] The self-locking motor drives the gear 16, and the gear 16 meshes with the arc plate 9 through the gear teeth 15, so that the arc plate 9 can rotate smoothly and accurately. Specifically, when the self-locking motor is started, the motor output shaft drives the gear 16 to rotate, and the gear teeth 15 on the gear 16 mesh with the gear 16 on the arc plate 9. The rotational motion of the gear 16 is transmitted to the arc plate 9 through the gear teeth 15, driving the arc plate 9 to rotate synchronously. This transmission method can not only provide sufficient torque to ensure that the arc plate 9 can still rotate stably under stress, but also achieve fine adjustment, so that the angle and position of each rotation are very accurate.

[0029] Through this arrangement, the position of the arc plate 9 can be easily adjusted so as to accurately clamp the badminton racket and perform corresponding tests. Whether it is necessary to fine-tune the clamping position or to significantly change the position of the badminton racket, it can be achieved by controlling the self-locking motor. This design improves the flexibility and convenience of operation, allowing the equipment to adapt to a variety of test requirements, thereby completing the precise adjustment of the position of the badminton racket after clamping.

[0030] In this embodiment, the height gauge assembly includes two guide blocks 17 installed at the second edge above the platform 1, a base 18 is slidably connected between the two guide blocks 17, a ruler frame 19 is fixedly connected above the base 18, a sliding assembly is slidably connected inside the ruler frame 19, and a digital display screen 20 is connected to one side of the sliding assembly. The position of the sliding assembly can be viewed in real time through the display screen, which provides intuitive feedback. The display screen can accurately display the current position and moving distance of the sliding assembly, and the parameters during the test process can be monitored and adjusted at any time. Such a real-time data display function greatly improves the accuracy and convenience of the operation, ensuring that each adjustment can achieve the desired effect.

[0031] The setting of the connection block 11 can adjust the position of the base 18, so that the device can adapt to badminton rackets of different lengths. Specifically, the connection block 11 is designed at the second edge above the platform 1, and the base 18 is connected to the platform 1 by a sliding connection. The base 18 can be easily moved by adjusting the position of the connection block 11, thereby adjusting the position of the sliding assembly and the height gauge assembly. This design makes the test device highly flexible, and it can be adapted to both short and long rackets through simple adjustments.

[0032] In this embodiment, the sliding assembly includes a sliding frame 21 that slides on the ruler frame 19, a threaded hole is provided on one side of the sliding frame 21, and a hand screw 22 is connected to the inner thread of the threaded hole. A support plate 23 for supporting the racket is fixedly connected to the side of the sliding frame 21 close to the connecting frame 2. The setting of the hand screw 22 facilitates the subsequent personnel to fix the position of the sliding frame 21. The hand screw 22 is simple in design and easy to operate. No additional tools are required. The position of the sliding frame 21 can be easily adjusted and fixed by manually rotating the screw. The adjustment process is simplified, the work efficiency is improved, and at the same time, it is ensured that the sliding frame 21 remains stable during the test process and will not be displaced due to vibration or external force. After the position of the sliding frame 21 is fixed, the other parts of the test device can also be more accurately aligned and adjusted, thereby ensuring the accuracy of the entire test process.

[0033] The support plate 23 is designed on one side of the sliding frame 21, moves with the sliding frame 21 and is fixed in an appropriate position. When the badminton racket is clamped in the device, the support plate 23 will be close to the end of the badminton racket, providing it with additional support and stability. This design can effectively prevent the badminton racket from sliding or falling due to gravity or external force during the test, ensuring that the racket is fixed more firmly and reliably.

[0034] In this embodiment, a through slot 24 is provided on the opposite side of the support plate 23, and an adjustment plate 25 is slidably connected to both sides of the inner wall of the through slot 24. A straight slot is provided on one side of the through slot 24, and a slider located in the straight slot is fixedly connected to one side of the adjustment plate 25. A screw 26 threadedly connected to the slider is rotatably connected inside the straight slot. By setting the screw 26, the two adjustment plates 25 can be simultaneously determined to slide synchronously. The screw 26 is designed on one side of the through slot 24, passes through the entire through slot 24, and is connected to the adjustment plate 25. The threads at both ends of the screw 26 are in opposite directions. When the screw 26 is rotated, the two adjustment plates 25 will slide in opposite directions. In this way, whether the adjustment plate 25 moves inward or expands outward, its symmetry and synchronization can be maintained, so that the adjusted gap is always centered on the through slot 24.

[0035] Secondly, the distance between the two adjustment plates 25 can be easily adjusted by rotating the screw rod 26 to adapt to badminton rackets of different models and specifications. Whether it is a narrow or wide racket frame, it can be adjusted to a suitable position by sliding the adjustment plate 25, thereby ensuring that the badminton racket can be firmly fixed in the through slot 24.

[0036] The adjustment plate 25 can be flexibly adjusted according to the width of different badminton rackets, ensuring that the racket frame is in the best position during each test to avoid sliding or loosening due to improper clamping. This adjustment method not only improves the applicability of the test device, but also enhances the simplicity and accuracy of its operation.

[0037] In this embodiment, the thread directions of the two ends of the screw rod 26 are opposite, and one end of the screw rod 26 extending out of the straight groove is fixedly connected to a crank. The setting of the crank facilitates the subsequent rotation of the screw rod 26.

[0038] In this embodiment, a threaded hole is provided on one side of the guide block 17, and a positioning screw 27 for fixing the position of the base 18 is threadedly connected in the threaded hole. The positioning screw 27 can be used to fix the position of the base 18.

[0039] In this embodiment, the four corners below the platform 1 are fixedly connected to the adjustable feet.
