Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, specifically to a large-aperture optical fiber rotating device. Background Technology

[0002] In the fields of fiber optic communication and sensing, fiber optic rotary connectors are crucial for achieving stable optical signal transmission between rotating and stationary components. Traditional rotary connectors (such as the BCS-35D) typically employ a single gear drive structure with a small opening, making the fiber prone to friction against the device's edge during rotation, leading to wear and even breakage. This design not only reduces the fiber's lifespan but also introduces additional signal loss and errors, affecting transmission stability and accuracy. Therefore, a large-aperture fiber optic rotary connector is proposed to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a large-aperture optical fiber rotating device. This device features a larger opening to accommodate thicker optical fibers, effectively preventing contact wear between the optical fiber and the device edge. Additionally, it offers more stable transmission between gears, thus solving the problems of small openings causing easy friction between the optical fiber and the device edge during rotation, as well as poor stability during optical fiber transmission.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a large-aperture optical fiber rotating device, comprising two foot blocks and a top cable tray plate, wherein protective shells are fixedly installed on both sides of the top of the cable tray plate, and a sealing cover is provided on the side of each of the two protective shells away from the cable tray plate, and a rotating structure for driving the optical fiber to rotate is provided inside each of the two protective shells.

[0005] The rotating structure includes an open gear, a fixed collar, two small transmission gears, a rotating mounting block, and an arc-shaped limiting block. The arc-shaped limiting block is fixedly mounted on the inner wall of the protective shell. The fixed collar is mounted on the inner ring of the arc-shaped limiting block. The rotating mounting block is sleeved on the inner ring of the fixed collar. The open gear is mounted between the sealing cover and the fixed collar. The connecting shaft of the rotating mounting block near the open gear is inserted into the collar of the fixed collar. The two small transmission gears are movably mounted between the arc-shaped limiting block and the sealing cover via bearings. Both small transmission gears simultaneously mesh with the open gear. An optical fiber clamping structure is provided on the top of the rotating mounting block.

[0006] Furthermore, a drive motor is fixedly installed on the side of the left foot block, and a drive gear is provided on the other side of the left foot block. The drive motor passes through the left foot block and is connected to the drive gear. Two drive shaft fixing piles are fixedly installed at the bottom of the bridge plate. A drive shaft is provided between the two drive shaft fixing piles. The two ends of the two drive shafts pass through the two foot blocks and extend to their outside. Driven gears are fixedly installed at both ends of the drive shafts. The two driven gears mesh with the two small transmission gears on the two rotating structures.

[0007] Furthermore, the optical fiber clamping structure includes a fixed plate, a clamping plate, a hinge shaft, an electromagnetic block, and an optical fiber clamping slot. The fixed plate is fixedly disposed on the top of the rotating mounting block. The hinge shaft is disposed on the back groove of the fixed plate. The clamping plate is movably disposed on the top of the fixed plate via the hinge shaft. The electromagnetic block is installed in the top groove of the fixed plate located at the bottom of the clamping plate. The optical fiber clamping slot is opened on the top of the fixed plate, and an optical fiber is disposed inside the optical fiber clamping slot.

[0008] Furthermore, the optical fiber clamping groove is concentrically arranged with the connecting shaft of the open gear, the fixed collar, and the rotating mounting block, and a metal iron block that attracts the electromagnetic block is provided at the bottom of the clamping plate.

[0009] Furthermore, the sealing cap, the open gear, the fixing collar, and the rotating mounting block all have V-shaped notches on their sides, allowing the optical fiber to pass through the middle.

[0010] Furthermore, the connecting shaft of the rotating mounting block near the open gear is fixed to the inner ring of the open gear by a fixing bolt, providing rotational power to the rotating mounting block.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. This large-aperture optical fiber rotating device achieves a larger opening to accommodate thicker optical fibers through the sealing cover, opening gear, fixing collar, and V-shaped notches on the rotating mounting block, while avoiding contact wear or even breakage of the optical fiber with the edge of the device.

[0013] 2. This large-aperture optical fiber rotating device drives two small transmission gears to rotate simultaneously through the driven gear, thereby driving the open gear to rotate. The two small transmission gears not only increase the stability of the open gear during transmission, but also ensure that one of the small transmission gears can always mesh with the open gear during transmission, thus solving the problem of poor stability that is easily caused by a single gear transmission.

[0020] 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.

[0021] Please see Figure 1-5 In this embodiment, a large-aperture optical fiber rotating device includes two foot blocks 1 and a top cable tray plate 2. Protective shells 7 are fixedly installed on both sides of the top of the cable tray plate 2 to restrict and protect the internal parts of the rotating structure 9. A sealing cover 10 is provided on the side of the two protective shells 7 away from the cable tray plate 2 to fix and seal the protective shells 7. A rotating structure 9 for driving the optical fiber to rotate is provided inside the two protective shells 7.

[0022] The rotating structure 9 includes an open gear 901, a fixed collar 902, two small transmission gears 903, a rotating mounting block 904, and an arc-shaped limiting block 905. The arc-shaped limiting block 905 is fixedly mounted on the inner wall of the protective shell 7, limiting the position of the fixed collar 902. The fixed collar 902 is located on the inner ring of the arc-shaped limiting block 905. The rotating mounting block 904 is sleeved on the inner ring of the fixed collar 902, and the fixed collar 902 can confine the rotating mounting block 904 to the fixed collar. The inner ring of ring 902 rotates, the open gear 901 is installed between the sealing cover 10 and the fixed collar 902, and the connecting shaft of the rotating mounting block 904 near the open gear 901 is inserted into the collar of the fixed collar 902. Two small transmission gears 903 are movably set between the arc-shaped limiting block 905 and the sealing cover 10 through bearings, and the two small transmission gears 903 mesh with the open gear 901 at the same time. The top of the rotating mounting block 904 is provided with an optical fiber clamping structure 6.

[0023] The rotating mounting block 904 has a connecting shaft on the side near the open gear 901 that is fixed to the inner ring of the open gear 901 by a fixing bolt, which provides the rotating power for the rotating mounting block 904.

[0024] In this embodiment, a drive motor 3 is fixedly installed on the side of the left foot block 1, serving as the drive source for the rotating device. A drive gear 4 is provided on the other side of the left foot block 1, and the drive motor 3 passes through the left foot block 1 and connects to the drive gear 4. The gear connected to the drive source serves as a transmission mechanism. Two drive shaft fixing posts 11 are fixedly installed at the bottom of the bridge plate 2. A drive shaft 12 is provided between the two drive shaft fixing posts 11, connecting the two driven gears 5 for transmission. The two ends of the two drive shafts 12 pass through the two foot blocks 1 and extend to their exteriors. Driven gears 5 are fixedly installed at both ends of the drive shafts 12. The two driven gears 5 mesh with two small transmission gears 903 on the two rotating structures 9, respectively, to drive the two small transmission gears 903 to rotate.

[0025] It should be noted that the rotating structure 9 drives the internal structure of the rotating structure 9 by simultaneously driving the two small transmission gears 903 inside the two rotating structures 9 with the two driven gears 5.

[0026] In this embodiment, the fiber optic clamping structure 6 includes a fixing plate 601, a clamping plate 602, a hinge shaft 603, an electromagnetic block 604, and a fiber optic clamping groove 605. The fixing plate 601 is fixedly disposed on the top of the rotating mounting block 904, serving to support the fiber optic clamping structure 6 and fix the rotating mounting block 904. The hinge shaft 603 is disposed on the back groove of the fixing plate 601. The clamping plate 602 is movably disposed on the top of the fixing plate 601 via the hinge shaft 603. The electromagnetic block 604 is installed in the top groove of the fixing plate 601 located at the bottom of the clamping plate 602. The fiber optic clamping groove 605 is opened on the top of the fixing plate 601, and an optical fiber 8 is disposed inside the fiber optic clamping groove 605.

[0027] The fiber optic clamping groove 605 is concentrically arranged with the connecting shaft of the open gear 901, the fixed collar 902 and the rotating mounting block 904, and a metal iron block that attracts the electromagnetic block 604 is provided at the bottom of the clamping plate 602.

[0028] It should be noted that the electromagnetic block 604 is a public technology known in the prior art, and its specific model and specifications will not be described in detail in this article.

[0029] Specifically, when it is necessary to fix the optical fiber 8 using the optical fiber clamping structure 6, the clamping plate 602 can be flipped open from the top of the fixing plate 601, then the optical fiber 8 can be placed into the optical fiber clamping slots 605 on the two fixing plates 601, then the clamping plate 602 can be pressed back onto the top of the fixing plate 601, and finally, the power is turned on so that the electromagnetic block 604 and the clamping plate 602 are attracted to each other to fix the optical fiber 8.

[0030] In this embodiment, the sealing cover 10, the open gear 901, the fixing collar 902, and the rotating mounting block 904 all have V-shaped notches on their sides so that the optical fiber 8 can pass through the middle.

[0031] It should be noted that the two ends of the fiber optic cable 8 are connected together by a winding device.

[0032] The working principle of the above embodiments is as follows:

[0033] When a rotating device is needed to rotate the fiber optic cable 8, the drive motor 3 can drive the drive gear 4 to rotate, which in turn causes a driven gear 5 meshing with the drive gear 4 to rotate. Since the driven gear 5 is connected to another driven gear 5 through the transmission shaft 12, the two driven gears 5 drive the two small transmission gears 903 inside the two protective housings 7 to rotate. The two small transmission gears 903 then mesh with the open gear 901, thereby driving the open gear 901 to rotate. The rotation of the open gear 901 can also drive the gears inserted into the open gear 901 to rotate. The rotating mounting block 904 is fixed on the 01 and rotates. During the rotation process, the rotating mounting block 904 can also be limited by the arc-shaped limiting block 905 and the fixing collar 902 to increase the stability of the rotation of the open gear 901. Finally, the fiber optic cable 8 is placed inside the fiber optic clamping slot 605. At the same time, the clamping plate 602 is placed on the electromagnetic block 604 on the fixing plate 601 for fixation. This achieves the advantages of avoiding damage or breakage of the fiber optic cable and the edge of the device due to excessive torque during the rotation process, and making the transmission between the gears more stable.
