Description

Technical Field

[0001] This utility model belongs to the field of Faraday rotator fixing technology, and in particular relates to a quick fixing device for Faraday rotators. Background Technology

[0002] A Faraday rotator is a magneto-optical device that uses the Faraday effect to rotate the polarization state of light and is widely used in various laser systems. Traditional Faraday rotators typically require multiple installation operations, including adjusting and aligning holes before securing them with screws. This method is cumbersome and time-consuming. Therefore, we propose a rapid fixing device for Faraday rotators. Utility Model Content

[0003] The purpose of this invention is to provide a quick fixing device for a Faraday rotator. Specifically, after the Faraday rotator is inserted into the fixing frame, the mounting sleeve is inserted into the front of the fixing frame. Then, the mounting sleeve is pushed, causing a pusher to push the Faraday rotator into the fixing frame. Next, an external hex wrench is used to rotate the rotating rod, causing the locking block to rotate to the rear of the fixing plate. At this point, the mating plate and the mounting plate are aligned. Bolts are then inserted into the mating plate and threadedly connected to the mounting plate, thus quickly fixing the mounting sleeve. This rapidly fixes the Faraday rotator, eliminating the need for frequent hole alignment by operators. The operation is simpler and more convenient, solving the problem that traditional Faraday rotator installation and fixing processes typically require multiple installation operations, hole adjustments, and are cumbersome and time-consuming.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a quick-fixing device for a Faraday rotator, comprising a housing with two fixing plates fixedly connected to each of the four inner sides of the housing. A fixing frame is disposed inside the housing, with the other end of each fixing plate fixedly connected to the outer surface of the fixing frame. A Faraday rotator is inserted into the fixing frame. A mounting assembly is disposed at the front of the fixing frame, comprising a mounting sleeve inserted into the front of the fixing frame. A fixing block is fixedly connected to the top of the mounting sleeve, and a rotating rod is rotatably connected inside the fixing block. A locking block is fixedly connected to the back of the rotating rod, and six external openings are formed on the front of the rotating rod. The mounting sleeve has four corners on its inner wall, each with a push block fixedly connected to it. The mounting sleeve also has four outer sides with connecting plates fixedly connected to it. The mounting frame has four outer sides with mounting plates fixedly connected to it. The connecting plates have internal holes, and the mounting plates have internal threaded holes. Bolts are inserted into the holes on the connecting plates and threadedly connected to the threaded holes on the mounting plates. After the mounting sleeve is inserted into the front of the mounting frame and pressed down, an external hex wrench is used to rotate the lever, causing the locking block to rotate behind the mounting plate for a limit position. At this point, the mounting sleeve can be released without needing to be pressed down again.

[0006] Furthermore, the back of the push block contacts the four corners of the front of the Faraday rotator. Two sliding grooves are provided on the left and right sides of the Faraday rotator. Two positioning sliders are fixedly connected to the left and right sides of the inner wall of the fixed frame. The Faraday rotator is slidably connected to the positioning sliders through the sliding grooves. The two sides of the Faraday rotator are inserted into the positioning sliders through the sliding grooves, which can improve the stability of the Faraday rotator.

[0007] Furthermore, a limiting rod is provided below the rotating rod, and the front of the limiting rod is fixedly connected to the back of the fixing block. The locking block is provided on the back of the fixing plate. When the locking block is in the lateral state, its bottom is in contact with the surface of the limiting rod, and its front is in contact with the back of the fixing plate. A protruding ring is fixedly connected to the outer surface of the rotating rod to limit the rotation of the rotating rod, so that the rotating rod rotates in the original position of the fixing block and does not deviate.

[0008] Furthermore, two push plates are provided inside the fixed frame, distributed at the top and bottom of the fixed frame. Limiting grooves are formed at the four corners of the inner wall of the fixed frame. A sliding rod is slidably connected inside the limiting groove. A spring is sleeved on the outside of the sliding rod. A limiting block is fixedly connected to the back of the sliding rod. The front of the sliding rod passes through the fixed frame and extends to the back of the push plate for fixed connection. The limiting block is used to limit the movement distance of the sliding rod. When the push plate is pushed, the sliding rod will move and stretch the spring.

[0009] Furthermore, the two upper sliding rods are connected to the upper push plate, and the two lower sliding rods are connected to the lower push plate. The outer side of the limiting block is slidably connected to the inner wall of the limiting groove. The front of the spring is fixedly connected to the inner wall of the limiting groove, and the back of the spring is fixedly connected to the front of the limiting block. The back of the Faraday rotator is in contact with the front of the push plate, and the outer side of the Faraday rotator is in contact with the inner side of the fixing frame. When the mounting cover is removed, the push plate will be pushed forward by the elasticity of the spring, and the Faraday rotator will be pushed forward, making it convenient for the staff to remove it.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, through the setting of an installation component, specifically involves inserting the Faraday rotator into the fixed frame, then inserting the mounting sleeve into the front of the fixed frame, and then pushing the mounting sleeve to push the Faraday rotator into the fixed frame. Subsequently, an external hex wrench is used to rotate the rotating rod, causing the locking block to rotate to the rear of the fixed plate. At this point, the mating plate and the mounting plate are aligned, and then the bolts are inserted into the mating plate to connect with the threaded connection of the mounting plate, thereby quickly fixing the mounting sleeve. Thus, the Faraday rotator is quickly fixed, eliminating the need for frequent alignment of the holes by the operator, making the operation simpler and more convenient.

[0012] 2. This utility model incorporates a push plate. Specifically, after the Faraday rotator is installed, the push plate will be pushed. When it is necessary to disassemble the Faraday rotator, the bolts are first removed, and then the mounting sleeve is taken out. At this time, the push plate will be pushed forward by the elastic force of the spring, and the Faraday rotator will be pushed forward. At this time, the front of the Faraday rotator extends a certain distance outside the fixing frame, making it convenient for the staff to pull the Faraday rotator out, which facilitates subsequent maintenance and other work.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 scope of protection of the present utility model.

[0025] Please see Figure 1-7As shown, this utility model is a quick fixing device for a Faraday rotator, including a housing 1. Two fixing plates 11 are fixedly connected to the four inner sides of the housing 1. A fixing frame 14 is provided inside the housing 1. The other end of the fixing plates 11 is fixedly connected to the outer surface of the fixing frame 14. A Faraday rotator 13 is inserted into the fixing frame 14. A mounting assembly 12 is provided in front of the fixing frame 14. The mounting assembly 12 includes a mounting sleeve 121 inserted into the front of the fixing frame 14. A fixing block 122 is fixedly connected to the top of the mounting sleeve 121. A rotating rod 221 is rotatably connected inside the fixing block 122. A locking block 222 is fixedly connected to the back of the rotating rod 221. An external hexagonal groove is opened on the front of the rotating rod 221. Push blocks 123 are fixedly connected to the four corners of the front of the inner wall of the mounting sleeve 121. A mating plate 124 is fixedly connected to the four outer sides of the mounting sleeve 121. A mounting frame 14 is fixedly connected to the four outer sides. Mounting plate 143 and mating plate 124 have internal holes and threaded holes. Bolts 125 are inserted into the holes on mating plate 124 and are threadedly connected to the threaded holes on mounting plate 143. After Faraday rotator 13 is inserted into fixing frame 14, mounting sleeve 121 is inserted into the front of fixing frame 14. Then, mounting sleeve 121 is pushed so that push block 123 pushes Faraday rotator 13 into fixing frame 14. Then, using an external hex wrench, rotating rod 221 is rotated so that locking block 222 rotates to the rear of fixing plate 11. At this time, mating plate 124 and mounting plate 143 are aligned. Then, bolts 125 are inserted into mating plate 124 and threadedly connected to mounting plate 143, thereby quickly fixing mounting sleeve 121. Faraday rotator 13 is quickly fixed, eliminating the need for frequent hole alignment by operators, making operation simpler and more convenient.

[0026] The back of the push block 123 contacts the four corners of the front of the Faraday rotator 13. Two sliding grooves are opened on the left and right sides of the Faraday rotator 13. Two positioning sliders 141 are fixedly connected to the left and right sides of the inner wall of the fixed frame 14. The Faraday rotator 13 is slidably connected to the positioning sliders 141 through the sliding grooves.

[0027] A limit rod 223 is provided below the rotating rod 221. The front of the limit rod 223 is fixedly connected to the back of the fixing block 122. The locking block 222 is provided on the back of the fixing plate 11. When the locking block 222 is in the horizontal state, the bottom of the locking block 222 contacts the surface of the limit rod 223, and the front of the locking block 222 contacts the back of the fixing plate 11.

[0028] The fixed frame 14 has two push plates 142 inside, located at the top and bottom of the frame. Limiting grooves are formed at the four corners of the inner wall of the fixed frame 14, with sliding rods 144 slidably connected inside each groove. Springs 146 are fitted around the outside of the sliding rods 144, and limiting blocks 145 are fixedly connected to the back of the sliding rods 144. The front of the sliding rods 144 passes through the fixed frame 14 and extends to the back of the push plates 142 for fixed connection. After the Faraday rotator 13 is installed, it pushes the push plates 142. When the Faraday rotator 13 needs to be disassembled, the bolts 125 are first removed, followed by the removal of the mounting sleeve 121. At this time, the push plates 142 are pushed forward by the elastic force of the springs 146, pushing the Faraday rotator 13 forward. The front of the Faraday rotator 13 extends a distance outside the fixed frame 14, making it easier for workers to pull it out for subsequent maintenance.

[0029] The two upper sliding rods 144 are connected to the upper push plate 142, and the two lower sliding rods 144 are connected to the lower push plate 142. The outer side of the limiting block 145 is slidably connected to the inner wall of the limiting groove. The front of the spring 146 is fixedly connected to the inner wall of the limiting groove, and the back of the spring 146 is fixedly connected to the front of the limiting block 145. The back of the Faraday rotator 13 is in contact with the front of the push plate 142, and the outer side of the Faraday rotator 13 is in contact with the inner side of the fixed frame 14.

[0030] One specific application of this embodiment is:

[0031] In use, the Faraday rotator 13 is placed inside the fixed frame 14, with both sides of the Faraday rotator 13 connected to the positioning slider 141 via grooves, which improves the stability of the Faraday rotator 13. After entering the fixed frame 14, the Faraday rotator 13 contacts the push plate 142. Then, the mounting sleeve 121 is inserted from the front of the fixed frame 14. At this time, the push block 123 inside the mounting sleeve 121 contacts the front of the Faraday rotator 13. Then, the mounting sleeve 121 is pushed, causing the push block 123 to push the Faraday rotator 13 into the fixed frame 14. The Faraday rotator 13 then pushes the push plate 142, and the slider 144 slides within the fixed frame 14, stretching the spring 146 through the limit block 145. When the inner side of the mounting sleeve 121 contacts the front of the fixed frame 14, the mating plate 124 and the mounting... When the plates 143 are joined together, the holes on the connecting plate 124 are aligned with the threaded holes on the connecting plate 124. At this time, the operator needs to continuously press the mounting sleeve 121, and then use an external hex wrench to insert into the front of the rotating rod 221 and rotate it to make the locking block 222 rotate to the rear of the fixing plate 11 and make the locking block 222 contact the limiting rod 223 to limit it. At this time, the mounting sleeve 121 can be released without pressing it again. The locking block 222 is locked by the fixing plate 11, and the mounting sleeve 121 will not be pushed forward. Then, the bolt 125 is inserted into the hole on the connecting plate 124 and threadedly connected to the threaded hole on the mounting plate 143 to fix the mounting sleeve 121. At this time, the mounting sleeve 121 pushes and fixes the Faraday rotator 13 through the push block 123, which can quickly complete the fixing work and improve efficiency.

[0032] When it is necessary to disassemble the Faraday rotator 13, first remove the bolt 125 to release the fixing of the mounting sleeve 121. Then, use an external hex wrench to rotate the rotating rod 221 so that the locking block 222 leaves the fixing plate 11 and contacts the limit of the mounting sleeve 121. At this time, remove the mounting sleeve 121, and the push plate 142 will be pushed forward by the elastic action of the spring 146, pushing the Faraday rotator 13 forward. At this time, the front of the Faraday rotator 13 extends a distance outside the fixing frame 14, making it convenient for the staff to pull the Faraday rotator 13 out, thus completing the disassembly.
