Rotating the handle counterclockwise can loosen the fixing plate from the wire, facilitating the disassembly of the wire.

[0003] The fiber-coupled acousto-optic modulators described above and in the prior art are installed and fixed with fixing bolts. This means that when replacing, maintaining or adjusting them, the fixing bolts need to be removed one by one, making quick installation and disassembly impossible. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot be quickly installed and disassembled, and to propose a variable, compact fiber-coupled acousto-optic modulator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a variable compact fiber-coupled acousto-optic modulator, comprising a modulator body, two mounting blocks on the bottom surface of the modulator body, each mounting block having a slot on its surface, a mounting base at the bottom of the modulator body, two mounting holes on the top surface of the mounting base, fixing brackets on both sides of the mounting base, two movable slots between the two mounting holes, two pressing holes between the two movable slots, a return spring inside each of the two pressing holes, two guide slots on both sides of the two movable slots, a locking block inside each of the two movable slots, a limiting rod on one side of each locking block, and a lever on the side of each locking block away from the limiting rod, two pressing rods on the surface of each locking block near the pressing hole, threaded holes on both sides of the mounting base, guide holes on both sides of the threaded holes, two guide rods on the surface of each of the two fixing brackets, and an adjusting screw in the middle of each of the two guide rods.

[0006] Preferably, the two mounting blocks are arranged in parallel at both ends of the bottom surface of the modulator body, and the positions of the mounting holes on the surface of the mounting base correspond one-to-one with the positions of the mounting blocks, and both mounting blocks are installed in the mounting holes.

[0007] Preferably, the two threaded holes are located at the middle position of the two side surfaces of the mounting base, and the two guide holes on both sides of the threaded holes are mirror images of the threaded holes, and all four guide holes are located on the surface of the mounting base.

[0008] Preferably, the two fixing brackets are mirror images of the mounting base, and the positions of the two guide rods on the surface of the two fixing brackets correspond one-to-one with the positions of the guide holes, and the guide rods are all installed in the guide holes. The two adjusting screws pass through the two fixing brackets and are installed in the threaded holes, and the adjusting screws are engaged with the fixing brackets.

[0009] Preferably, both of the movable slots are located inside the mounting base and are connected to the two mounting holes. The two guide slots on both sides of the two movable slots are mirror images of the movable slots and are located on the surface of the mounting base. All four guide slots are connected to the movable slots. The two ends of the two extrusion holes in the middle of the two movable slots are connected to the two movable slots and are located inside the mounting base.

[0010] Preferably, both of the card blocks are installed inside the two movable slots, the positions of the extrusion rods on the surfaces of the two card blocks correspond one-to-one with the positions of the extrusion holes, and the extrusion rods are installed inside the extrusion holes. The return springs inside the two extrusion holes are located between the two extrusion rods inside the extrusion holes.

[0011] Preferably, the slots on the surfaces of the two mounting blocks are both located on one side of the movable groove, and the internal locking blocks of the movable groove are both installed in the slots. The two limiting rods are both installed in the guide groove, and one end of each limiting rod passes through the movable groove and is threadedly connected to the locking block. The two toggle blocks are both installed in the guide groove, and one end of each toggle block passes through the movable groove and is threadedly connected to the locking block.

[0012] Beneficial effects

[0013] In this invention, during installation, the mounting base is first fixed to the mounting point using fixing bolts. After installation, the mounting block at the bottom of the modulator body is aligned and pushed into the mounting hole of the mounting base. When the mounting block enters the mounting hole, since the mounting hole is connected to the movable groove, the mounting block will press the locking block in the movable groove, causing the locking block to move deeper into the movable groove. When the modulator body is fully installed, the pressing rod on the locking block will be pushed by the force of the return spring, causing the locking block to quickly pop out and lock into the locking groove on the surface of the mounting block. This completes the fixed installation. The entire installation process does not require additional bolt tightening; simply pressing the modulator body into place is sufficient, greatly improving installation efficiency. For disassembly, simply move both levers simultaneously towards the center. The levers will cause the locking block to disengage from the locking groove of the mounting block. Once the locking block disengages, the mounting block of the modulator body is no longer fixed, and the modulator body can then be easily pulled upwards to complete disassembly, solving the shortcomings of not being able to perform quick installation and disassembly.

The two locking blocks 10 each have two pressing rods 11 on the surface near the pressing hole 12. The mounting base 2 has threaded holes 7 on both sides, and guide holes 4 on both sides of each threaded hole 7. The two fixing brackets 5 each have two guide rods 6 on their surfaces, and adjusting screws 8 are located in the middle of each guide rod 6. Two mounting blocks 15 are parallel to each other at both ends of the bottom surface of the modulator body 1, and the positions of the mounting holes 14 on the surface of the mounting base 2 correspond one-to-one with the positions of the mounting blocks 15. Both mounting blocks 15 are installed in the mounting holes 14. The two threaded holes 7 are located in the middle of both sides of the mounting base 2, and the two guide holes 4 on both sides of the threaded holes 7 are mirror images of each other with the threaded holes 7 as the center. All four guide holes 4 are located on the mounting base 2. On the surface of base 2, two fixed brackets 5 are mirror images of the mounting base 2. The positions of the two guide rods 6 on the surfaces of the two fixed brackets 5 correspond one-to-one with the positions of the guide holes 4, and the guide rods 6 are all installed in the guide holes 4. Two adjusting screws 8 pass through the two fixed brackets 5 and are installed into the threaded holes 7, and the adjusting screws 8 are engaged with the fixed brackets 5. Two movable slots 9 are located inside the mounting base 2, and both movable slots 9 communicate with the two mounting holes 14. Two guide slots 3 on both sides of the two movable slots 9 are mirror images of the movable slots 9, and the guide slots 3 are all located on the surface of the mounting base 2. All four guide slots 3 communicate with the movable slots 9. Two extrusion holes 12 are located between the two movable slots 9. Both ends are connected to two movable slots 9, and the extrusion hole 12 is located inside the mounting base 2. Two locking blocks 10 are installed inside the two movable slots 9. The extrusion rods 11 on the surface of the two locking blocks 10 are positioned one-to-one with the positions of the extrusion holes 12, and the extrusion rods 11 are installed in the extrusion holes 12. The return springs 13 inside the two extrusion holes 12 are located between the two extrusion rods 11 inside the extrusion holes 12. The locking grooves 16 on the surface of the two mounting blocks 15 are located on one side of the movable slot 9, and the locking blocks 10 inside the movable slot 9 are installed into the locking grooves 16. Two limiting rods 17 are installed in the guide grooves 3, and one end of each limiting rod 17 passes through the movable slot 9 and is threadedly connected to the locking block 10. Two toggle blocks 18 are installed in the guide grooves 3.Furthermore, one section of the lever 18 extends into the movable groove 9 and is threadedly connected to the locking block 10.

[0025] The modulator body 1 is the core carrier of the entire acousto-optic modulator, integrating a compact optical path modulation structure. Two parallel mounting blocks 15 are located at the bottom of the modulator body 1. Each mounting block 15 has a groove 16 machined on its surface, and these grooves 16 are located on one side of the movable slot 9. Initial fixation is achieved by the mounting blocks 15 engaging with the mounting holes 14 of the mounting base 2. The bottom mounting base 2 supports and fixes the modulator body 1. The mounting holes 14 on the top surface of the mounting base 2 correspond one-to-one with the positions of the mounting blocks 15 on the modulator body 1, accommodating the mounting blocks 15 and communicating with the movable slot 9. This allows the mounting blocks 15 installed in the mounting holes 14 to push the retaining blocks 10 extending from the movable slot 9 back into the movable slot 9. The movable slot 9 is located between the two mounting holes 14, accommodating the retaining blocks 10 and providing a track and space for their movement. Guide grooves 3 are provided on both sides of the movable slot 9 and communicate with it, accommodating the limiting rod 17 and the toggle block 18. The movable groove 9 also has a compression hole 12 in the middle, and both ends of the compression hole 12 are connected to the movable groove 9. The compression hole 12 is used to accommodate the return spring 13 and provide space for the compression rod 11 of the locking block 10 to move. The compression rods 11 of both locking blocks 10 are inserted into the compression hole 12 and contact the return spring 13. When the two locking blocks 10 are pressed inward by the mounting block 15, the compression rods 11 on both sides of the return spring 13 will compress the return spring 13, causing the return spring 13 to be compressed and store elastic potential energy. When the mounting block 15 is installed in place, the locking groove 16 of the mounting block 15 is aligned with the locking block 10. When the pressure is removed, the return spring 13 releases energy to push the locking block 10 to reset, so that the locking block 10 quickly pops out of the movable groove 9 and locks into the locking groove 16 on the surface of the mounting block 15 in the mounting hole 14. The limiting rod 17 on one side of the two locking blocks 10 is installed in the guide groove 3, and one end is threaded to the locking block 10. It restricts the movement direction of the locking block 10 by moving in the guide groove 3. The lever 18 is installed in two guide grooves 3 on the other side of the mounting base 2, with one end threadedly connected to the locking block 10. By moving the lever 18, the locking block 10 can be moved. The fixing bracket 5 is mounted on both sides of the mounting base 2 in a mirror-like arrangement, with guide rods 6 on its surface. The guide rods 6 are inserted into the guide holes 4 of the mounting base 2, allowing the fixing bracket 5 to move horizontally through the engagement with the guide holes 4. The adjusting screw 8 passes through the fixing bracket 5 and is installed in the threaded hole 7 of the mounting base 2. By engaging with the threads in the threaded hole 7, the fixing bracket 5 moves axially along the adjusting screw 8 when the adjusting screw 8 is rotated, thereby adjusting the lateral position of the fixing bracket 5 to adapt to pre-embedded installation points with different spacing, achieving flexible fixing of the mounting base 2. Specific Implementation Example 2:

[0027] Reference Figure 1-5A variable compact fiber-coupled acousto-optic modulator, further based on the basic structure in Specific Embodiment 1, involves placing the mounting base 2 in a preset installation position during installation. Rotating the adjusting screws 8 on the fixing brackets 5 on both sides of the mounting base 2 causes the fixing brackets 5 to move axially, thereby adjusting their lateral position. This accommodates pre-embedded installation points with different spacing, ensuring the device's wide applicability. During movement, the guide rod 6 moves within the guide hole 4 to ensure stable movement of the fixing brackets 5.

[0028] Once the position is adjusted, the mounting bracket 5 can be securely fixed to the mounting holes using fixing bolts. This completes the installation of the mounting base 2. After the mounting base 2 is fixed, the modulator body 1 can be installed. During installation, align the two mounting blocks 15 at the bottom of the modulator body 1 with the mounting holes 14 on the top surface of the mounting base 2. Then push them into the mounting holes 14. Once the slots 16 of the mounting blocks 15 align with the locking blocks 10 in the movable slot 9, the compressive force acting on the locking blocks 10 disappears. At this time, the compressed return spring 13 immediately releases its energy, pushing the locking blocks 10 to quickly pop out of the movable slot 9 and precisely engage with the slots 16 on the surface of the mounting blocks 15. This completes the rapid fixing of the modulator body 1 without the need for any additional bolts, thus improving installation efficiency.

[0029] When it is necessary to remove the modulator body 1, the user simply needs to simultaneously move both levers 18 towards the center. Since the two levers 18 are threaded onto the locking block 10, the moving levers 18 will cause the locking block 10 to move inward, disengaging it from the slot 16 of the mounting block 15. Once the locking block 10 disengages from the slot 16, the mounting block 15 at the bottom of the modulator body 1 is no longer secured, allowing the user to easily pull the modulator body 1 upward to complete the disassembly.

[0030] In summary:

[0031] 1. During installation, first use fixing bolts to fix the mounting bracket 5 of the mounting base 2 to the installation point. After installation, align the mounting block 15 at the bottom of the modulator body 1 and push it into the mounting hole 14 of the mounting base 2. When the mounting block 15 enters the mounting hole 14, since the mounting hole 14 is connected to the movable groove 9, the mounting block 15 will squeeze the locking block 10 in the movable groove 9, causing the locking block 10 to move deeper into the movable groove 9. When the modulator body 1 is fully installed, the pressing rod 11 on the locking block 10 will be pushed by the force of the return spring 13, causing the locking block 10 to quickly pop out and lock into the locking groove 16 on the surface of the mounting block 15. This completes the fixed installation. The entire installation process does not require additional bolt tightening; simply pressing the modulator body 1 into place is sufficient, greatly improving installation efficiency. For disassembly, simply move both levers 18 towards the center simultaneously. The levers 18 will cause the locking block 10 to disengage from the locking groove 16 of the mounting block 15. Once the locking block 10 is disengaged, the mounting block 15 of the modulator body 1 is no longer secured, and the modulator body 1 can be easily pulled upwards to complete the disassembly, thus solving the problem of not being able to perform quick installation and disassembly.
