[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0021] like Figures 1-4 As shown, this utility model provides a tennis ball pressure resistance testing device, including a support base 1, a support frame 2, and a hydraulic cylinder 3. The support frame 2 is fixed to the top of the support base 1, and reinforcing plates 17 are fixed to both sides of the support frame 2. The bottom of the reinforcing plates 17 is fixed to the top surface of the support base 1. The air guide channel 11 is set in an L-shape to cooperate with the air inlet of the detection groove 9 and the fan 6. The hydraulic cylinder 3 is set on the top of the support frame 2. The output end of the hydraulic cylinder 3 passes through the inside of the support frame 2 and is fixed to the detection pressure plate 4. The pressure sensor 5 is set on the top of the detection pressure plate 4. The input end of the pressure sensor 5 is fixed to the bottom surface of the detection pressure plate 4. The detection support plate 8 is fixed on the top surface of the support base 1. The detection groove 9 is opened at the center of the detection support plate 8. The air guide channel 11 is opened inside the support base 1 at the bottom of the detection groove 9. The air inlet groove 10 is symmetrically opened inside the detection groove 9 and communicates with the inside of the air guide channel 11. The fan 6 with the air outlet away from the support base 1 is set on the side of the support base 1. The end of the fan 6 away from the support base 1 is threaded with a dust cover 7.

[0022] The specific settings and functions of this embodiment are described in detail below: The air inlet 10 is an arc-shaped air inlet 10 that cooperates with the detection 9. Both the air inlet 10 and the dust cover 7 are fixed with dustproof nets. The top surface of the dustproof net at the bottom of the air inlet 10 is flush with the bottom surface of the detection 9, ensuring that the tennis ball can be stably placed inside the detection 9. When detecting slippage, the airflow is drawn into the air guide channel 11 through the air inlet 10. The suction force generated by the airflow drives the tennis ball to be stably placed inside the detection 9, thereby ensuring the stability of the detection and preventing the tennis ball from jumping out of the detection 9. Moreover, when feeding, the tennis ball can be directly placed inside the detection 9 without supporting it and keeping it stationary inside the detection 9. Example 2

[0023] like Figures 1-4 As shown, a transparent protective plate 12 is slidably fitted inside the support frame 2 on the outside of the detection pressure plate 4. The transparent protective plate 12 is a hollow rectangle that cooperates with the support frame 2, the detection pressure plate 4, and the detection tray 8. A handle is fixed to the middle of the front side of the transparent protective plate 12. The height of the transparent protective plate 12 is equal to the height between the bottom surface of the detection pressure plate 4 and the top surface of the support base 1. Slider blocks 13 are fixed on both sides of the transparent protective plate 12. The sliders 13 are slidably fitted inside the grooves 14 opened on both sides of the support frame 2. A spring 15 is fixed between the top surface of each slider 13 and the top surface of the groove 14. A slide rod 16 is slidably fitted inside each slider 13 and spring 15. A sliding hole that cooperates with the slide rod 16 is opened inside each slider 13. Both ends of the slide rod 16 are fixed to the upper and lower walls of the groove 14.

[0024] The overall effect of this embodiment is that by folding the tennis ball with the transparent protective plate 12, the tennis ball is prevented from breaking under excessive pressure and causing debris to fly everywhere, affecting the safety of the testing personnel. In addition, the transparent design of the transparent protective plate 12 makes it easy to observe the state of the tennis ball. At the same time, the transparent protective plate 12 can further prevent the tennis ball from jumping out of the support base 1.

[0025] The usage and working principle of this device are as follows: When testing is required, hold the handle and push the transparent protective plate 12 upwards, causing the transparent protective plate 12 to drive the slider 13 to slide upwards inside the slide groove 14. At the same time, the spring 15 is compressed. Then, place the tennis ball into the detection groove 9 and release the handle. The transparent protective plate 12, pushed by the spring 15, abuts against the top surface of the support base 1. At this time, the fan 6 runs and draws air into the air guide channel 11 through the air inlet groove 10, and then discharges through the air guide channel 11, the fan 6, and the dust cover 7. Under the action of suction, the tennis ball can be quickly fixed inside the detection groove 9. Then, the hydraulic cylinder 3 runs and drives the detection pressure plate 4 to move downwards. The detection pressure plate 4 moves downwards and squeezes the tennis ball. At this time, the pressure sensor 5 detects the pressure generated when the detection pressure plate 4 moves downwards. When the tennis ball breaks, it is blocked by the transparent protective plate 12 on the detection tray 8, which facilitates the collection of debris. If the tennis ball does not break, pull the transparent protective plate 12 upwards again to remove the tennis ball.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
