Description

Technical Field

[0001] This utility model relates to the field of optical fiber take-up and take-up device technology, specifically an optical fiber reel with a positioning structure. Background Technology

[0002] Currently, in the processes of fiber optic cable laying, optical communication testing, and optoelectronic equipment installation, the winding and unwinding of fiber optic cables is typically accomplished manually or through semi-automatic reel mechanisms. Traditional fiber optic reels mostly employ a fixed structure, with their axis fixed to the base. Winding and unwinding of the fiber is achieved through manual rotation or a motor driven in one direction. While this type of structure can meet basic requirements for winding and unwinding in a single direction, when the fiber laying path or winding / unwinding direction changes frequently, the fixed structure cannot flexibly adjust the reel angle, leading to entanglement, twisting, and excessive bending of the fiber during winding and unwinding. In severe cases, this can even cause fiber core breakage or increased transmission loss.

[0003] Some existing improvement solutions employ detachable reels or external brackets to adjust the winding direction of the reel, enabling multi-angle cable deployment. However, these structures generally suffer from the following problems: First, the adjustment mechanism is complex and inconvenient to operate, making rapid direction switching impossible; second, there is a lack of unified linkage control between the winding reel and the transmission components, often requiring repositioning and calibration after direction adjustment, affecting deployment and take-up efficiency; third, during automated operation, the rotation of the winding reel and the drive unit lack precise synchronous control, resulting in uneven fiber tension or unstable deployment and take-up.

[0004] Furthermore, most existing fiber optic reels use a single-motor direct drive or belt drive, which cannot precisely control the winding speed and direction. Although some structures include a turntable or support frame, these typically only allow for minor angle adjustments and cannot maintain the smoothness of the fiber optic path in multi-directional cabling scenarios, nor can they balance structural stability with equipment compactness.

[0005] In summary, existing fiber optic reels generally suffer from limitations in directional adjustment, low automation, uneven winding, and complex operation, making it difficult to meet the application requirements of high precision, multi-directional, and automated deployment and take-up in modern fiber optic laying projects. Therefore, there is an urgent need for a compact, freely positionable fiber optic reel with automatic drive capabilities to achieve efficient and safe deployment and take-up of optical fibers in multi-angle scenarios. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is: an optical fiber reel with a positioning structure, including a base, a turntable assembly, an optical fiber winding wheel, and a drive assembly.

[0008] Several circumferentially distributed guide shafts are rotatably mounted on the surface of the base to support and limit the rotation of the rotating components. The turntable assembly includes a base and a trunnion fixed to the surface of the base. A bearing plate is provided on the bottom surface of the base and is rotatably mounted inside the base to support the overall rotation of the turntable assembly. The fiber optic wheel is rotatably mounted inside the trunnion, with a transmission gear fixedly mounted on one side. The drive assembly includes a motor, a gear ring, a transmission gear set, and a bevel gear shaft arranged through the base. The motor is fixed to the surface of the base, and its output end is connected to the surface of the gear ring for transmission. The gear ring and the bearing plate are both rotatably mounted inside the base and slide in contact with the guide shaft surfaces. The transmission gear set meshes with one end of the bevel gear shaft inside the gear ring for transmission, and the other end of the bevel gear shaft meshes with the transmission gear of the fiber optic wheel to achieve power transmission.

[0009] Through the above structural design, the fiber optic winding wheel can be rotated and positioned in multiple directions, and its automated drive can be extended and retracted, which significantly improves the flexibility and control accuracy of fiber optic operations.

[0010] In a preferred example, the fiber optic wheel is rotatably mounted inside two oppositely arranged lumens and is arranged parallel to each other along the axial direction, with the deflection axis of the pedestal perpendicular to the axis of the fiber optic wheel.

[0011] Specifically, this structure enables the fiber winding wheel to form a spatial orthogonal relationship between the vertical and horizontal directions, ensuring a uniform distribution of winding tension, avoiding fiber overlap and twisting, and improving the stability of winding and unwinding.

[0012] In a preferred example, the bevel gear shaft is arranged through the pedestal and rotatably mounted inside the shaft lug for meshing with the optical fiber winding drive gear.

[0013] Specifically, the bevel gear shaft converts horizontal driving force into vertical rotational force through bevel gear meshing structure, achieving smooth torque transmission and ensuring stable speed and balanced torque during retraction and extension operations in different directions.

[0014] In a preferred example, the transmission gear set includes two meshing gear shafts, one of which is coaxially arranged with a gear ring and meshes with the surface of a bevel gear shaft, and the other gear shaft meshes with the inner side of the gear ring on one side.

[0015] Specifically, this dual-stage gear shaft transmission structure achieves speed regulation and torque amplification through gear ratio distribution, which can maintain constant tension output under different cable winding and unwinding speeds, thereby improving the stability and responsiveness of the drive system.

[0016] In a preferred example, a speed sensor is fixedly mounted on the surface of the base for connection with the bevel gear shaft surface to monitor the winding rotation rate of the fiber optic wheel.

[0017] Specifically, the speed sensor can monitor the rotation speed signal of the winding wheel in real time and feed it back to the control system for dynamic adjustment, so as to achieve precise control of the fiber optic take-up and take-up rate and avoid fiber overstretching or stacking caused by speed fluctuations.

[0018] In a preferred example, the guide shaft includes a connecting pin and a plurality of bearings arranged on the surface of the connecting pin, the bearings sliding against the surfaces of the bearing plate and the gear ring.

[0019] Specifically, this guide structure can reduce rotational friction and achieve stable support for the turntable assembly during rotational positioning, thereby improving overall rotational accuracy and service life.

[0020] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the rotatable connection structure between the bearing plate and the base allows the turntable assembly to rotate freely in the horizontal plane, thereby realizing multi-directional adjustment of the fiber winding wheel. It can adapt to the fiber winding and unwinding requirements under different wiring directions, effectively avoiding the problems of twisting, tangling and bending damage to the fiber during the winding process, and significantly improving the smoothness of fiber winding and unwinding and the flexibility of operation.

[0021] 2. In this utility model, by setting a drive assembly consisting of a motor, a gear ring, a transmission gear group and a bevel gear shaft, active drive control of the optical fiber winding wheel is realized. The optical fiber winding and unwinding operations can be automatically completed as needed. Combined with the free rotation positioning function of the turntable group, the entire system can realize automated operation, which significantly improves the operating efficiency and operational safety of the optical fiber management device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an optical fiber reel with a positioning structure.

[0027] Combination Figures 1-4 As shown, the present invention provides an optical fiber reel with a positioning structure, including a base 100, a turntable assembly 200, an optical fiber winding wheel 300, and a drive assembly 400.

[0028] The surface of the base 100 is rotatably mounted with a plurality of circumferentially distributed guide shafts 110, which are used to support the rotating components and provide limiting guidance.

[0029] The turntable assembly 200 includes a base 210 and a lug bracket 220 fixed to the surface of the base 210. The bottom surface of the base 210 is provided with a bearing plate 211, which is rotatably mounted on the inner side of the base 100 to support the entire turntable assembly 200 to rotate and be positioned on the horizontal plane.

[0030] The fiber optic winding wheel 300 is rotatably mounted on the inner side of the shaft lug 220, and a transmission gear 310 is fixedly mounted on one side of the fiber optic winding wheel 300.

[0031] The drive assembly 400 includes a motor 410, a gear ring 420, a transmission gear set 430, and a bevel gear shaft 440 arranged through the base 210. The motor 410 is fixedly mounted on the surface of the base 100, and its output end is connected to the surface of the gear ring 420 for transmission. The gear ring 420 and the bearing plate 211 are both rotatably mounted on the inner side of the base 100 and slide in contact with the surface of the guide shaft 110, thereby forming circumferential support during rotation. The transmission gear set 430 is used for meshing transmission between the inner side of the gear ring 420 and one end of the bevel gear shaft 440, and the other end of the bevel gear shaft 440 meshes with the surface of the transmission teeth 310 of the fiber optic winding wheel 300, thereby realizing the step-by-step transmission of rotational power.

[0032] The base 100 serves as the main support for the entire device, and guide shafts 110 are evenly distributed on its surface to support rotating components and provide low-friction support.

[0033] The turntable assembly 200 forms a rotational positioning mechanism through the rotational engagement between the bearing plate 211 and the base 100, enabling the turntable assembly 200 to achieve multi-angle rotational adjustment on the base 100.

[0034] The pedestal 210 is fixedly installed above the bearing plate 211, and the shaft lugs 220 are fixedly installed on both sides of the pedestal 210 to support the two ends of the fiber optic winding wheel 300.

[0035] The fiber optic wheel 300 is rotatably mounted inside the shaft lug 220 and is connected to the bevel shaft 440 via the transmission gear 310.

[0036] The drive assembly 400 is powered by a motor 410, the output of which is connected to a gear ring 420. Both the gear ring 420 and the bearing plate 211 are mounted inside the base 100 and are guided by a guide shaft 110. The transmission gear set 430 is located inside the gear ring 420 and is used to transmit rotational force to the bevel gear shaft 440, which ultimately drives the optical fiber winding wheel 300 to rotate, realizing the winding and unwinding of the optical fiber.

[0037] Specifically, through the coordinated action of the base 100, turntable assembly 200 and drive assembly 400, the structure enables the fiber optic winding wheel 300 to rotate and position freely in the horizontal plane, and also to achieve power-driven extension and retraction control, thereby improving the flexibility and automation of the equipment.

[0038] In this embodiment, the fiber optic wheel 300 is rotatably mounted inside two opposing trunnions 220, forming a stable double-support structure. The fiber optic wheel 300 is arranged parallel to the axial direction, and its rotation axis is perpendicular to the rotation axis of the turntable assembly 200. The platform 210 is arranged in the deflection direction, and its central axis is orthogonal to the axial direction of the fiber optic wheel 300, so that the rotation surface of the wheel and the rotation surface of the turntable are perpendicular to each other.

[0039] Specifically, the design uses spatial orthogonal arrangement to ensure that the fiber optic winding wheel 300 maintains uniform tension during the winding and unwinding process, avoiding fiber optic overlap or twisting, which is beneficial for orderly fiber optic arrangement and stable optical signal transmission.

[0040] In this embodiment, the bevel gear shaft 440 is arranged through the pedestal 210 and is supported at both ends by bearing seats and mounted inside the shaft lug 220. One end of the bevel gear shaft 440 meshes with the transmission gear set 430, and the other end meshes with the transmission gear 310 of the fiber optic wheel 300. The horizontal rotational force is converted into the vertical rotational force through the bevel gear meshing, so as to achieve smooth torque transmission.

[0041] Specifically, this structure makes the power transmission path compact and energy loss small, effectively ensuring the stable rotation of the fiber optic wheel 300, avoiding vibration or eccentricity caused by off-center load, and improving the reliability of the drive system.

[0042] In this embodiment, the transmission gear set 430 includes two meshing gear shafts. The first gear shaft is coaxially arranged with the gear ring 420, and its tooth surface meshes with the bevel gear shaft 440; the second gear shaft is located adjacent to the first gear shaft, and its tooth surface meshes with the inner teeth of the gear ring 420. This two-stage gear shaft structure can adjust the rotational speed and torque during transmission, achieving controllable retraction and extension speeds.

[0043] Specifically, this structure achieves torque amplification and smooth transmission through a two-stage gear shaft connection, ensuring that the fiber optic winding wheel 300 can start and stop smoothly under different loads, thus improving the driving accuracy and service life of the winding wheel.

[0044] In this embodiment, a speed sensor is fixedly mounted on the surface of the base 100. This sensor is connected to the surface of the bevel gear shaft 440 and is used to monitor the rotational speed of the fiber optic wheel 300 in real time. The signal output of the speed sensor can be used in conjunction with the motor 410 control module to achieve automatic speed adjustment.

[0045] Specifically, this structure enables closed-loop control of the fiber optic deployment and take-up process, preventing fiber optic stacking or stretching caused by unstable speed, thereby improving operational safety and fiber optic protection performance.

[0046] In this embodiment, the guide shaft 110 includes a connecting pin and a plurality of bearings arranged on the surface of the connecting pin. The outer rings of the bearings slide against the outer surfaces of the bearing disc 211 and the gear ring 420, respectively, to reduce rotational friction and improve rotational accuracy and stability.

[0047] Specifically, this structure provides stable support when the turntable assembly 200 rotates, making the rotation smoother, reducing sway and vibration, and thus ensuring the reliability and long-term stability of the fiber optic reel during operation.

[0048] Working principle and usage process of this utility model: This utility model comprises a base 100, a turntable assembly 200, an optical fiber winding wheel 300, and a drive assembly 400.

[0049] During use, the bearing plate 211 can rotate freely relative to the base 100, allowing the turntable assembly 200 to rotate and be positioned horizontally, thereby adjusting the facing angle of the fiber winding wheel 300 to adapt to different fiber introduction or winding paths. When fiber winding or unwinding operations are required, the drive assembly 400 is activated, wherein the motor 410 drives the fiber winding wheel 300 and its drive gear 310 to rotate synchronously through the gear ring 420, the transmission gear assembly 430 and the bevel gear shaft 440, realizing automatic fiber winding or unwinding.

[0050] During the winding process, the optical fiber is smoothly wound from the outside of the winding wheel 300 to the center, achieving directional arrangement and storage. During the unwinding process, the drive component 400 drives in the opposite direction, and the optical fiber is output in the opposite direction along the guide groove of the winding wheel 300, maintaining uniform fiber tension. Through the rotatable structure of the bearing plate 211, the winding direction of the optical fiber can be automatically switched at different winding and unwinding positions, effectively avoiding the tangling and crossing problems of traditional optical fiber reels during multi-directional winding and unwinding.

[0051] The overall structure achieves multi-angle adjustable and automated winding and unwinding control through the free rotation of the turntable assembly 200 and the synchronous transmission of the drive assembly 400. It has the advantages of smooth winding, accurate positioning, convenient operation and reliable structure.
