[0024] Reference Figures 1 to 5This utility model discloses a sprint testing device that is easy to fix, comprising a main body 5. A worm gear 23 is rotatably connected to the upper surface of the main body 5. A fixing rod 24 is fixedly connected to the upper surface of the worm gear 23. A rotating disk 16 is fixedly connected to the upper surface of the fixing rod 24. A guide groove 17 is provided on the upper surface of the rotating disk 16. A connecting plate 19 is fixedly connected to the upper surface of the main body 5. A sliding groove 20 is provided on the upper surface of the connecting plate 19. A moving plate 18 is slidably connected in the sliding groove 20. A guide post 21 is fixedly connected to the moving plate 18 near the guide groove 17. The guide post 21 and the guide groove 17 are slidably connected. A fixing post 22 is fixedly connected to the upper surface of the guide post 21. A positioning shaft 25 is rotatably connected to the inner side wall of the main body 5. A worm gear 15 is fixedly connected to the side surface of the positioning shaft 25. A rotating component 6 is rotatably connected to the surface of the main body 5. The rotating component 6 passes through the surface of the main body 5 and is fixedly connected to the other end of the worm gear 15. The worm gear 15 meshes with the worm gear 23. A fixing seat 1 is provided on the upper surface of the main body 5. The guide groove 17 is arc-shaped, with one end extending to the center of the rotating disk 16 and the other end near the periphery. This design allows the guide posts 21 to move closer to or further apart from each other.

[0025] A connecting plate 4 is fixedly connected to the lower surface of the main body 5. A threaded post 8 is fixedly connected to the lower surface of the connecting plate 4. A fixing ring 14 is fixedly connected to the lower surface of the fixing seat 1. A fixing groove 13 is provided on the inner wall of the fixing ring 14. A camera 2 is fixedly connected to the upper surface of the fixing seat 1. A display panel 3 is fixedly connected to the fixing seat 1 near the camera 2. The camera 2 and the display panel 3 are electrically connected. The structural design of the worm gear 15 and the worm wheel 23 has excellent self-locking characteristics, which helps to prevent the rotating disk 16 from rotating accidentally due to external interference, thereby avoiding accidental release of the lock on the fixing seat 1.

[0026] A rotating shaft 10 is rotatably connected to the inner wall of the mounting groove 12. A support column 11 is fixedly connected to the surface of the rotating shaft 10. A counterweight is provided at the bottom of the support column 11. The connecting seat 9 is triangular in shape. The surface of the connecting seat 9 is provided with the mounting groove 12. A threaded sleeve 7 is threadedly connected to the lower surface of the threaded column 8. The connecting seat 9 is fixedly connected to the lower surface of the threaded sleeve 7.

[0027] Working Principle: Before use, first adjust the height of the device. Rotate the threaded column 8 within the threaded sleeve 7 to adjust to a suitable height. Next, unfold the support column 11 and allow the rotating shaft 10 to rotate within a defined range. The square face at the top of the support column 11 engages with the mounting groove 12, while the counterweight at the bottom ensures the device is stable in the testing area. Subsequently, the camera 2 captures data during the sprint and transmits the information to the display panel 3 for a clear view of each athlete's performance. When maintaining or replacing components such as the camera 2, rotate the rotating part 6, which drives the worm gear 15 to rotate on the positioning shaft 25. The rotation of the worm gear 15 then drives the worm wheel 23, which in turn rotates the connected rotating disk 16. The guide groove 17 on the surface of the rotating disk 16 is arc-shaped. When rotated to a certain angle, the moving plate 18 moves towards the rotating disk 16 within the sliding groove 20. The guide posts 21 on the surface of the moving plate 18 move within the guide groove 17. Multiple guide posts 21 move towards the center under the constraint of the guide groove 17, causing the fixing posts 22 to disengage from the fixing groove 13 of the fixing ring 14, thus facilitating replacement. During installation, the fixing ring 14 is placed close to the main body 5, and then the rotating component 6 is rotated in the opposite direction, causing the fixing posts 22 to separate from the center to the surrounding area under the action of the guide groove 17, thereby fixing the component.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
