[0002] A laser emitter is a device that can generate and emit laser light. It generates laser light through a specific laser medium (such as gas, solid, liquid or semiconductor) and emits it after focusing or collimating the laser light through an optical system. Different application scenarios may require different laser power. In order to flexibly adjust the power and adapt to various complex application requirements, a tunable laser emitter power continuous adjustment slider mechanism is used.

[0003] A tunable laser emitter power continuous adjustment slider mechanism is a device used to precisely control the output power of a laser emitter. It moves a slider via a slider rod, thereby changing the laser's power output. In existing laser emitter frequency adjustment technologies, adjusting the laser emitter frequency is relatively cumbersome, and the movement of the slider cannot be well controlled, making it difficult to meet the needs of different applications.

[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 a continuously adjustable power sliding mechanism for a tunable laser emitter, comprising a vertical plate 1, a first motor 2 fixedly connected to the outer wall of the vertical plate 1, a rotating shaft 3 fixedly provided at the output end of the first motor 2, a turntable 4 fixedly connected to the outer wall of the rotating shaft 3, a fixed shaft 5 fixedly connected to the outer wall of the turntable 4, a rotating plate 6 rotatably connected to the outer wall of the fixed shaft 5, a connecting shaft 7 rotatably connected to the inside of the rotating plate 6, a connecting plate 8 fixedly connected to the outer wall of the connecting shaft 7, a limiting groove 25 formed inside the connecting plate 8, a support shaft 9 fixedly connected to the inside of the connecting plate 8, a sliding rod 10 rotatably connected to the outer wall of the support shaft 9, a sliding groove 11 formed inside the sliding rod 10, the outer wall of the connecting plate 8 rotatably connected to the inner wall of the sliding groove 11, and a support assembly provided on the upper surface of the vertical plate 1.

[0024] Specifically, the upright plate 1 fixes the first motor 2. Driven by the first motor 2, the rotating shaft 3 can rotate stably inside the upright plate 1. The rotating shaft 3 fixes the turntable 4, allowing the turntable 4 to rotate synchronously through the transmission of the rotating shaft 3. The turntable 4 fixes the fixed shaft 5, thereby driving the fixed shaft 5 to rotate synchronously. The fixed shaft 5 connects the turntable 4 and the rotating plate 6, allowing the turntable 6 to rotate synchronously through the rotation of the turntable 4. The connecting shaft 7 connects the turntable 6 and the connecting plate 8, allowing the connecting plate 8 to rotate through the rotation of the turntable 6. The connecting plate 8 fixes the support shaft 9. When the connecting plate 8 rotates, it drives the support shaft 9 to rotate inside the sliding rod 10, thereby pushing the sliding rod 10 to slide through the rotational connection. The design of the groove 11 provides rotational space for the connecting plate 8.

[0025] Reference Figure 2 The support assembly includes a support plate 13, the lower surface of the support plate 13 is fixedly connected to the upper surface of the upright plate 1, the outer wall of the support plate 13 is fixedly connected to a support block 12, the outer wall of the sliding rod 10 is slidably connected to the inside of the support block 12, and the outer wall of the sliding rod 10 is fixedly connected to a slider 26.

[0026] Specifically, the support plate 13 supports and fixes the upright plate 1, and the support block 12 is fixed to the outer wall of the support plate 13 to limit the sliding of the sliding rod 10 and prevent deviation during the sliding process. The sliding rod 10 fixes the slider 26, allowing the slider 26 to slide synchronously with the sliding rod 10, thereby changing the position between the conductive contact and the resistive film on the slider 26. By changing the resistance value, the power of the laser emitter can be continuously adjusted.

[0027] Reference Figure 2 and Figure 4 A second motor 14 is fixedly connected inside the support plate 13. A worm gear 15 is fixedly installed at the output end of the second motor 14. The outer wall of the worm gear 15 is rotatably connected to the inside of the support plate 13. A support frame 16 is rotatably connected to the outer wall of the worm gear 15. The outer wall of the support frame 16 is fixedly connected to the outer wall of the support plate 13. A worm wheel 17 is meshed with the tooth end of the worm gear 15. A threaded rod 18 is fixedly connected inside the worm wheel 17. A fixed plate 19 is rotatably connected to the outer wall of the threaded rod 18. The outer wall of the fixed plate 19 is fixedly connected to the outer wall of the support plate 13. A threaded block 20 is threadedly connected to the outer wall of the threaded rod 18. Limiting posts 21 are fixedly connected to both sides of the threaded block 20. A connecting plate 22 is provided on the outer wall of the limiting posts 21. A support post 23 is fixedly connected to one end of the connecting plate 22. The outer wall of the support post 23 is rotatably connected to the inside of the support plate 13. A sliding post 24 is fixedly connected to the other end of the connecting plate 22. The outer wall of the sliding post 24 is slidably connected to the inner wall of the limiting groove 25.

[0028] Specifically, the support plate 13 fixes the second motor 14, and the second motor 14 drives the worm 15 to rotate stably inside the support plate 13. The support frame 16 is fixed to the outer wall of the support plate 13 to support the rotation of the worm 15. The worm 15 meshes with the worm wheel 17, allowing the worm wheel 17 to rotate synchronously with the rotation of the worm 15. The worm wheel 17 fixes the threaded rod 18, allowing the threaded rod 18 to rotate synchronously with the rotation of the worm wheel 17. The fixing plate 19 is fixed to the outer wall of the support plate 13 to provide stable support for the rotation of the threaded rod 18. The threaded rod 18 is threadedly connected to the threaded block 20, allowing the threaded block 20 to slide through the rotation of the threaded rod 18. The threaded block 20 fixes the limiting post 21, which can carry... The movable limiting post 21 slides synchronously. The limiting post 21 is set inside the connecting plate 22. When the limiting post 21 slides, it can push the connecting plate 22 and the support post 23 to rotate. The support post 23 rotates inside the support plate 13 and can provide stable support for the rotation of the connecting plate 22. The connecting plate 22 plays a role in fixing the sliding post 24, so that it slides inside the limiting groove 25 through the rotation of the connecting plate 22. By changing the position of the sliding post 24, the rotation angle of the connecting plate 22 can be limited, thereby limiting the movable distance of the sliding rod 10. When the sliding post 24 is located on the left side of the limiting groove 25, the sliding range of the sliding rod 10 is reduced. When the sliding post 24 is located on the right side of the limiting groove 25, the sliding range of the sliding rod 10 will increase, thereby achieving more precise power adjustment.

[0029] Working principle: When this mechanism is needed, the position of the sliding column 24 in the figure is located to the right of the limiting groove 25. The first motor 2 is started to drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it will drive the turntable 4 and the fixed shaft 5 to rotate at the same time. During the rotation of the fixed shaft 5, it will drive the connecting shaft 7 to rotate through the rotating plate 6. The rotation of the connecting shaft 7 will drive the connecting plate 8 to rotate. The connecting plate 8 will drive the support shaft 9 to rotate inside the sliding rod 10. During the rotation, it will push the sliding rod 10 to slide inside the support block 12, thereby adjusting the position of the slider 26. The slider 26 is provided with conductive contacts. The conductive contacts are in contact with the resistive diaphragm of the potentiometer. When the slider 26 moves, the position of the conductive contacts on the resistive diaphragm changes, thereby changing the resistance value of the potentiometer. By adjusting the position of the slider 26, the position of the conductive contacts and the resistive diaphragm is changed, thereby changing the resistance value and achieving the effect of continuous adjustment of the power of the laser emitter.

[0030] When precise adjustment of the laser emitter frequency is required, the position of the sliding column 24 is moved so that it slides to the left side of the limiting groove 25. The second motor 14 is then started to drive the worm gear 15 to rotate. When the worm gear 15 rotates, it drives the worm wheel 17 at the tooth end to rotate. During the rotation of the worm wheel 17, it drives the internal threaded rod 18 to rotate. During the rotation of the threaded rod 18, it drives the threaded block 20 on the outer wall and the limiting column 21 to slide. Thus, the sliding of the limiting column 21 pushes the connecting plate 22 to drive the sliding column 24 to slide on the inner wall of the limiting groove 25. When the sliding column 24 slides to the other side of the limiting groove 25, the rotation angle of the connecting plate 8 can be limited. This mechanism limits the sliding distance of the sliding rod 10 and the sliding distance of the slider 26, thereby achieving more precise adjustment and flexible control of the sliding distance of the slider 26. This reduces adjustment errors caused by the fixed stroke of the slider 26, improving the accuracy of power adjustment. The mechanism not only allows for continuous power adjustment of the laser emitter by changing the position of the conductive contacts and resistive diaphragm through adjusting the slider 26, but also enables flexible control of the sliding distance of the slider 26, reducing adjustment errors caused by the fixed stroke of the slider 26 and improving the accuracy of power adjustment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
