[0008] Furthermore, an insertion rod is slidably sleeved on each of the two ratchets, and two circular holes are provided on the front side of the turntable, and the two insertion rods are adapted to the two circular holes.

[0009] Furthermore, the configuration mechanism includes a rotating component and several fixed components, the rotating component includes a base plate arranged at the bottom of the turntable, the top of the base plate is fixedly connected to a semicircular block module, the front of the semicircular block module is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to a rotating shaft through a coupling.

[0010] Furthermore, the rotating shafts all pass through the semicircular block module and the turntable and are rotatably connected to the semicircular block module and fixedly connected to the turntable.

[0011] Furthermore, arc grooves are provided on the front and back of the semicircular block module, a balance rod is fixedly sleeved on the turntable, and the front and rear ends of the balance rod extend into the two arc grooves and are slidably connected to the two arc grooves.

[0012] Furthermore, the fixing assembly includes a screw rod slidably sleeved on the bottom plate, the outer wall of the screw rod is threadedly sleeved with a manual turntable, and the bottom of the manual turntable is in contact with the bottom plate.

Through this setting, the complex steps of installation and disassembly can be effectively reduced, and the installation efficiency can be significantly improved.

[0016] (2) The present invention provides a configuration mechanism. During use, if the working angle of the Faraday rotator needs to be adjusted, the motor can be started. The motor will drive the turntable and the Faraday rotator fixed on the turntable to rotate to a suitable angle through the rotating shaft.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0028] See also Figure 1-6 As shown, the utility model is a Faraday rotator that is easy to install, including a turntable 1, on which a mounting mechanism 2 and a configuration mechanism 3 are provided:

[0029] The mounting mechanism 2 includes a slide groove 21 provided on the front of the turntable 1. A slide plate 22 is slidably connected to the inner wall of the slide groove 21. A Faraday rotator 23 is fixedly connected to the top of the slide plate 22. Two mounting grooves 1 24 are provided on the front of the turntable 1. Slide blocks 25 are slidably connected to the inner walls of the two mounting grooves 1 24. Slide rods 26 are fixedly connected to the inner walls of the two mounting grooves 1 24. The two slide rods 26 pass through the two slide blocks 25 and are slidably connected to the two slide blocks 25. The outer walls of the two slide rods 26 are wound with springs 1 27. The two springs One end of each spring 27 is fixedly connected to the two mounting grooves 24, and the other ends of each spring 27 are fixedly connected to the two sliders 25. The front sides of the two sliders 25 are fixedly connected with ratchet blocks 28, and the two ratchet blocks 28 are adapted to the slide plate 22. The front side of the turntable 1 is rotatably connected to two pawls 29, and the two pawls 29 are adapted to the two ratchet blocks 28. A plug rod 291 is slidably sleeved on the two pawls 29. Two circular holes 292 are provided on the front side of the turntable 1, and the two plug rods 291 are adapted to the two circular holes 292.

[0030] By providing a mounting mechanism, during operation, the pawl 29 can be moved upward, thereby releasing its limit on the ratchet block 28. Then, the insertion rod 291 on the pawl 29 is inserted into the circular hole 292 on the turntable 1 to achieve temporary fixation of the pawl 29. This operation facilitates pulling the ratchet block 28 to both sides, providing space for the smooth insertion of the slide 22 at the bottom of the Faraday rotator 23. At the same time, when the ratchet block 28 is pulled, the slider 25 on the ratchet block 28 will apply pressure to the spring 27 on the outer wall of the slide rod 26, storing energy and preparing for the subsequent reset operation. Next, the slide 22 at the bottom of the Faraday rotator 23 can be inserted into the slide groove 21 on the turntable 1. After the insertion is completed, the two ratchet blocks 28 are released. Under the combined action of the spring 1 27 and the slide bar 26, the slider 25 will drive the ratchet blocks 28 to move closer to each other, so that the slide 22 can be restrained in the slide groove 21. If it is necessary to strengthen the fixation of the ratchet blocks 28, the insertion rods 291 on the two pawls 29 can be pulled out, causing the pawls 29 to rotate downward and restrain the ratchet blocks 28. This arrangement can effectively reduce the complex steps of installation and disassembly, significantly improving installation efficiency.

[0031] The configuration mechanism 3 includes a rotating component and several fixed components. The rotating component includes a bottom plate 31 arranged at the bottom of the turntable 1. The top of the bottom plate 31 is fixedly connected to a semicircular block module 32. The front of the semicircular block module 32 is fixedly connected to a motor 33. The output shaft of the motor 33 is fixedly connected to a rotating shaft 34 through a coupling. The rotating shaft 34 passes through the semicircular block module 32 and the turntable 1 and is rotatably connected to the semicircular block module 32 and fixedly connected to the turntable 1. The front and back of the semicircular block module 32 are both provided with arc grooves 35. The semicircular block module 32 is fixed on the turntable 1. A balance rod 36 is sleeved, and the front and rear ends of the balance rod 36 extend into the two arc-shaped grooves 35 and are slidably connected to the two arc-shaped grooves 35. The fixing assembly includes a screw 37 slidably sleeved on the base plate 31. The outer wall of the screw 37 is threadedly sleeved with a manual turntable 38. The bottom of the manual turntable 38 is in contact with the base plate 31. The outer wall of the screw 37 is provided with a mounting groove 2 39. The inner wall of the mounting groove 2 39 is rotatably connected to two folding rods 391. The side of the two folding rods 391 close to each other is fixedly connected to a spring 2 392.

[0032] By configuring the configuration mechanism, if the operating angle of the Faraday rotator 23 needs to be adjusted during use, the motor 33 can be activated. The motor 33 drives the turntable 1 and the Faraday rotator 23 fixed thereto via the rotating shaft 34 to rotate to a suitable angle. Simultaneously, as the turntable 1 rotates, the balancing bar 36 on the turntable also slides synchronously within the arcuate groove 35 on the semicircular block module 32. This configuration allows the turntable 1 to more smoothly adjust the angle of the Faraday rotator 23.

[0033] A specific application of this embodiment is a Faraday rotator: an optical device that utilizes the Faraday effect and can change the polarization direction of light passing through it by applying an external magnetic field. When light passes through the Faraday rotator, the magnetic field affects the propagation speed of the light wave, thereby rotating the polarization plane of the light. The rotation angle is related to factors such as the intensity of the magnetic field, the propagation direction of the light, and the wavelength. It is widely used in optical measurement, communications, laser technology, and other fields.

[0034] During operation, the pawl 29 can be moved upward to release the limit on the ratchet block 28. Then, the insertion rod 291 on the pawl 29 is inserted into the circular hole 292 on the turntable 1 to achieve temporary fixation of the pawl 29. This operation facilitates pulling the ratchet block 28 to both sides, providing space for the smooth insertion of the slide 22 at the bottom of the Faraday rotator 23. At the same time, when the ratchet block 28 is pulled, the slider 25 on the ratchet block 28 will apply pressure to the spring 27 on the outer wall of the slide rod 26, storing energy and preparing for the subsequent reset operation. Next, you can Insert the slide 22 at the bottom of the Faraday rotator 23 into the slide groove 21 on the turntable 1. After the insertion is completed, release the two ratchet blocks 28. Under the combined action of the spring 1 27 and the slide rod 26, the slider 25 will drive the ratchet blocks 28 to move closer to each other, so that the slide 22 can be restricted in the slide groove 21. If it is necessary to strengthen the fixation of the ratchet blocks 28, the insertion rods 291 on the two pawls 29 can be pulled out, so that the pawls 29 rotate downward and restrict the ratchet blocks 28. This arrangement can effectively reduce the complex steps of installation and disassembly, and significantly improve installation efficiency. During use If the working angle of the Faraday rotator 23 needs to be adjusted, the motor 33 can be started. The motor 33 will drive the turntable 1 and the Faraday rotator 23 fixed to the turntable to rotate to a suitable angle through the rotating shaft 34. At the same time, during the rotation of the turntable 1, the balance bar 36 on the turntable will also slide synchronously in the arc groove 35 on the semicircular block module 32. Through this arrangement, the turntable 1 can drive the Faraday rotator 23 to adjust the angle more smoothly. If the entire device needs to be fixed, the screw 37 can be inserted into the fixing hole on the bottom plate 31. During the insertion process, the two folding rods 391 on the screw 37 will be squeezed by the wall of the fixed hole, thereby compressing the spring 2 392 therein, so that the two folding rods 391 can retract into the mounting groove 2 39 on the screw 37 to avoid affecting the penetration of the screw 37. When the screw 37 is completely penetrated, the two folding rods 391 will be reset under the action of the elastic force of the spring 2 392. At this time, the screw 37 can be contracted by rotating the manual turntable 38 to cooperate with the two folding rods 391, thereby achieving stable fixation of the entire device. This setting can reduce the tedious fixation process.
