[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: an integrated acoustic-optic modulator, including a lower housing 1, a mounting plate 14 fixedly installed on the bottom inner wall of the lower housing 1, and an upper housing 8 above the lower housing 1. A heat dissipation box 10 is fixedly installed on the top of the upper housing 8, and locking blocks 7 are fixedly installed at the four corners of the bottom of the upper housing 8. Handles 9 are fixedly installed on both sides of the top of the upper housing 8. The lower housing 1 has slots 5 around its perimeter that are adapted to the locking blocks 7, and multiple heat dissipation holes 2 are opened on both sides of the lower housing 1. Data connectors 4 are fixedly installed on both sides of the lower housing 1. A mounting cavity 18 is opened inside the mounting plate 14, and L-shaped fixing plates 15 are fixedly installed on both sides of the top of the mounting plate 14. Two... Two rotating shafts 19 are rotatably mounted within the mounting cavity 18 and slide rod 22. The same sliding sleeve 21 is slidably sleeved on the two slide rods 22. A mounting rod 20 is fixedly mounted on the top of the sliding sleeve 21. A return spring 23 is fixedly sleeved between the two slide rods 22 and the sliding sleeve 21. L-shaped movable plates 16 are fixedly mounted on both sides of the mounting rod 20. The same sound and light modulator body 6 is provided between the two L-shaped movable plates 16 and the two L-shaped fixed plates 15. A worm gear 17 is rotatably mounted within the mounting cavity 18. Worm wheels 24 and extrusion discs 25 are fixed on the two rotating shafts 19. The two worm wheels 24 mesh with the worm gear 17. A knob 3 is fixedly sleeved on one end of the worm gear 17. The two rotating shafts 19 are located at the eccentric positions of the corresponding extrusion discs 25.

[0029] In this embodiment, the integrated acoustic-optic modulator mainly consists of components such as a lower housing 1, an upper housing 8, a mounting plate 14, an L-shaped fixed plate 15, an L-shaped movable plate 16, a worm gear 17, a rotating shaft 19, and an extrusion disc 25.

[0030] Working principle: The slot 5 on the lower housing 1 and the locking block 7 on the upper housing 8 enable quick installation and disassembly between the lower housing 1 and the upper housing 8. This design not only simplifies the installation process but also facilitates subsequent maintenance of the acousto-optic modulator body 6 inside the lower housing 1.

[0031] Fixing method: The main body 6 of the sound and light modulator is held between two L-shaped fixed plates 15 and two L-shaped movable plates 16. By rotating the knob 3, the worm gear 17 is rotated, which in turn drives the two worm wheels 24 to rotate. Since the worm wheels 24 are fixedly connected to the rotating shaft 19, the rotating shaft 19 also rotates, which in turn drives the extrusion disc 25 to rotate. Both extrusion discs 25 press the sliding sleeve 21 to the left. Since the sliding sleeve 21 slides on the sliding rod 22 and is subjected to the elastic force of the return spring 23, the movement of the sliding sleeve 21 will drive the mounting rod 20 and the two L-shaped movable plates 16 to move to the left, thereby achieving quick and easy fixing of the main body 6 of the sound and light modulator. This design can flexibly fix the main body 6 of the sound and light modulator according to different lengths.

[0032] CombinationFigures 1-5 As shown, in this embodiment, two cooling fans 13 are fixedly installed inside the heat sink 10, and an air outlet is provided at the junction of the heat sink 10 and the upper shell 8. Multiple heat dissipation fins 12 are fixedly installed inside the air outlet, and dustproof nets 11 are snapped into the air inlets of the two cooling fans 13.

[0033] In this embodiment, during implementation:

[0034] Heat dissipation components: Two cooling fans 13 are fixedly installed inside the heat dissipation box 10. An air outlet is provided at the junction of the heat dissipation box 10 and the upper shell 8. Multiple heat dissipation fins 12 are fixedly installed inside the air outlet.

[0035] Working principle: The heat dissipation fins 12 contact the acoustic-optical modulator body 6, increasing the heat dissipation area of ​​the acoustic-optical modulator body 6. The cooling fan 13 accelerates the airflow through forced convection, thereby improving the heat dissipation efficiency. When the cooling fan 13 is working, air enters from the air inlet of the heat dissipation box 10, and after heat exchange between the heat dissipation fins 12 and the acoustic-optical modulator body 6, the air carrying heat is discharged from the heat dissipation box 10.

[0036] Dustproof design: In order to prevent dust and other impurities from entering the cooling fan 13 and affecting the heat dissipation effect, dustproof nets 11 are provided at the air inlets of both cooling fans 13 in this embodiment. The dustproof nets 11 can effectively block external dust and impurities from entering the cooling fan 13 and ensure the long-term stable operation of the heat dissipation structure.

[0037] Working principle of this utility model:

[0038] Flexible fixing: The slot 5 on the lower housing 1 and the locking block 7 on the upper housing 8 facilitate quick installation and disassembly between the lower housing 1 and the upper housing 8, and facilitate later maintenance of the acoustic-optic modulator body 6 inside the lower housing 1. By locking the acoustic-optic modulator body 6 between the two L-shaped fixed plates 15 and the two L-shaped movable plates 16, and then rotating the knob 3 to drive the rotation of the worm gear 17, the worm gear 17 drives the rotation of the two worm wheels 24, which in turn drives the rotation of the two rotating shafts 19 and the two extrusion discs 25. The two extrusion discs 25 both press the sliding sleeve 21 to the left, which drives the two L-shaped movable plates 16 to move to the left. With the help of the two L-shaped fixed plates 15, the acoustic-optic modulator body 6 can be quickly fixed and installed, which is convenient for fixing and installing acoustic-optic modulator bodies 6 of different lengths.

[0039] Heat dissipation structure design: The integrated acoustic and optical modulator has a built-in heat sink 10. The heat sink 10 is equipped with heat dissipation fins 12 and a cooling fan 13. The heat dissipation fins 12 are in contact with the main body 6 of the acoustic and optical modulator. The heat dissipation fins 12 increase the heat dissipation area of ​​the main body 6 of the acoustic and optical modulator. The cooling fan 13 accelerates the air flow through forced convection to improve the heat dissipation efficiency. Dustproof nets 11 are provided at the air inlets of the two cooling fans 13 to prevent dust and other impurities from entering the cooling fans 13 and ensure the long-term stable operation of the heat dissipation structure.

[0040] In summary, the integrated acoustic-optic modulator of this utility model, through its efficient heat dissipation mechanism and flexible installation and fixing mechanism, ensures both long-term stable operation and ease of installation and maintenance.
