[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an anti-counterfeiting fiber fluorescence detection device, including a connecting plate 1, a fixing frame 2 fixedly connected to the upper surface of the connecting plate 1, a first rotating shaft 3 rotatably connected inside the fixing frame 2, a support frame 4 fixedly connected to the outer wall of the first rotating shaft 3, a cylinder 5 fixedly connected to the outer wall of the support frame 4, a push block 6 fixedly connected to the output end of the cylinder 5, a second rotating shaft 7 rotatably connected inside the push block 6, a rotating block 8 fixedly connected to the outer wall of the second rotating shaft 7, a third rotating shaft 9 fixedly connected inside the rotating block 8, the outer wall of the third rotating shaft 9 rotatably connected inside the connecting plate 1, a pressure plate 10 fixedly connected to the lower surface of the rotating block 8, and a support assembly provided on the lower surface of the connecting plate 1;

[0024] Specifically, the connecting plate 1 supports and fixes the fixed frame 2, the fixed frame 2 supports the first rotating shaft 3, the support frame 4 fixes the first rotating shaft 3, and the support frame 4 also fixes the cylinder 5. During the operation of the cylinder 5, it will also rotate slightly, which allows the support frame 4 to drive the first rotating shaft 3 to rotate inside the fixed frame 2. The start of the cylinder 5 can push the push block 6 to slide. The push block 6 supports the second rotating shaft 7, which can slide synchronously with the push block 6. The rotating block 8 fixes the second rotating shaft 7, which can rotate through the sliding of the second rotating shaft 7. The rotating block 8 fixes the third rotating shaft 9, which can rotate stably inside the connecting plate 1 through the rotation of the rotating block 8. The rotating block 8 fixes the pressure plate 10, which can rotate synchronously through the rotation of the rotating block 8. By adjusting the angle of the pressure plate 10, samples of different thicknesses can be limited and pressed.

[0025] Reference Figure 1 The support assembly includes a base plate 11, the upper surface of which is fixedly connected to the lower surface of the connecting plate 1, and a placement platform 12 is provided on the upper surface of the base plate 11.

[0026] Specifically, the base plate 11 serves to fix the connecting plate 1 and the placement stage 12, through which the sample to be tested can be placed.

[0027] Reference Figure 1 and Figure 4 A bracket 13 is fixedly connected to the upper surface of the base plate 11. A motor 14 is fixedly connected to the outer wall of the bracket 13. A threaded rod 15 is fixedly provided at the output end of the motor 14. The outer wall of the threaded rod 15 is rotatably connected to the inside of the bracket 13. A first slider 16 is threadedly connected to the outer wall of the threaded rod 15. A first connecting shaft 17 is rotatably connected to both sides of the first slider 16. One end of a rotating plate 18 is fixedly connected to the outer wall of the first connecting shaft 17. A second connecting shaft 19 is fixedly connected to the other end of the rotating plate 18. The outer wall of the second connecting shaft 19 rotates... A connecting frame 20 is connected; a second slider 21 is threadedly connected to the outer wall of the threaded rod 15, and a third connecting shaft 22 is rotatably connected to both sides of the second slider 21; one end of a rotating frame 23 is fixedly connected to the outer wall of the third connecting shaft 22, and the other end of the rotating frame 23 is fixedly connected to the inside of the connecting frame 20; a sliding plate 24 is fixedly connected to the lower surface of the connecting frame 20, a limit strip 25 is slidably connected inside the sliding plate 24, the outer wall of the limit strip 25 is fixedly connected to both sides of the bracket 13, and a detection mechanism 26 is provided on the lower surface of the sliding plate 24;

[0028] Specifically, the bracket 13 is fixed to the upper surface of the base plate 11, which serves to fix the motor 14. When the motor 14 is started, its driving action causes the threaded rod 15 to rotate stably inside the bracket 13. The threaded rod 15 is threadedly connected to the first slider 16, which slides synchronously with the rotation of the threaded rod 15. The first slider 16 supports the first connecting shaft 17, allowing it to slide synchronously. The first connecting shaft 17 connects the first slider 16 and the rotating plate 18, thus causing the rotating plate 18 to rotate. The rotating plate 18 supports the second connecting shaft 19, which connects the rotating plate 18 and the connecting frame 20. The sliding plate 24 fixes the connecting frame 20 and will slide due to rotation. Similarly, the threaded rod 15... 5 is threadedly connected to the second slider 21. The second slider 21 supports the third connecting shaft 22. The rotating frame 23 fixes the third connecting shaft 22, thereby allowing the rotating frame 23 to rotate. The rotating frame 23 fixes the second connecting shaft 19, thereby driving the connecting frame 20 and the slide plate 24 to slide. The synchronous rotation of the rotating plate 18 and the rotating frame 23 can drive the slide plate 24 to slide. The limiting strip 25 is fixed on both sides of the bracket 13 to limit the sliding of the slide plate 24 and prevent the slide plate 24 from deviating during the sliding process. The slide plate 24 supports and fixes the detection mechanism 26, and the position of the detection mechanism 26 can be flexibly adjusted. The detection mechanism 26 is a prior art technology, including an ultraviolet light source, an optical system, a detector and a spectrometer, which can capture and analyze fluorescence signals.

[0029] Working principle: When the device is needed, the sample to be tested for anti-counterfeiting is placed on the upper surface of the placement stage 12. The cylinder 5 is activated, which pushes the push block 6 to slide. When the push block 6 slides, it drives the second rotating shaft 7 to slide. During the sliding process, the second rotating shaft 7 drives the rotating block 8 to rotate. When the rotating block 8 rotates, it simultaneously drives the third rotating shaft 9 to rotate inside the connecting plate 1. Thus, the rotation of the rotating block 8 drives the pressure plate 10 to rotate. By adjusting the angle of the two pressure plates 10, the sample can be pressed and limited, thereby limiting the position of the sample and ensuring that the distance and angle between the light source and the sample remain consistent, thus improving the accuracy of the test.

[0030] When a sample needs to be tested, motor 14 is started, which drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, it causes the first slider 16 and the second slider 21 on both sides to slide synchronously. When the first slider 16 slides, it drives the rotating plate 18 to rotate via the first connecting shaft 17. During rotation, the rotating plate 18 pulls the connecting frame 20 to slide via the second connecting shaft 19. When the second slider 21 slides, it drives the rotating frame 23 to rotate via the third connecting shaft 22. During rotation, the rotating frame 23 also pulls the connecting frame 20 to slide via the second connecting shaft 19. Thus, the combined rotation of the rotating plate 18 and the rotating frame 23 drives... The sliding plate 24 slides, which drives the detection mechanism 26 to slide, allowing for flexible adjustment of the height of the detection mechanism 26. The detection mechanism 26 enables anti-counterfeiting fluorescence detection of samples, facilitating the positioning of the detection mechanism 26 to the optimal detection position. This meets the detection needs of different sample types, improving detection flexibility. This device not only limits the position of the sample, ensuring that the distance and angle between the light source and the sample remain consistent, thus improving detection accuracy, but also facilitates the positioning of the detection mechanism 26 to the optimal detection position, meeting the detection needs of different sample types and enhancing detection flexibility.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
