[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] This utility model provides an auxiliary traction device for fiber optic docking, referring to... Figures 1 to 4 In this embodiment, the main body of the device is a housing 1, which constitutes the supporting and protective outer shell of the entire device. A handle 9 is installed on the top of the housing 1, and shock-absorbing pads 19 are provided on the bottom. The handle 9 facilitates the carrying and transportation of the device, making it suitable for various construction environments such as machine rooms, corridors, and the field. The shock-absorbing pads 19 protect the components inside the housing 1 from vibration and impact during docking operations, improving the stability of the device when placed. Additionally, a back plate 12 is provided on the side of the housing 1 away from the changing plate 2. The housing 1 and the back plate 12 are connected by bolts, facilitating disassembly for maintenance of the components inside the housing 1.

[0017] like Figure 2 As shown, a door 3 is hinged to one side of the housing 1, and a coil 8 for pre-winding the optical fiber 18 is installed on the inner wall of the door 3. This allows the optical fiber 18 to be stored inside the door 3 before traction, facilitating its access during connection. A limit block 14 is provided on the inner wall of the door 3, and a matching limit plate 13 is installed on the inner wall near the hinge point between the housing 1 and the door 3. When the door 3 is opened to the working position, i.e., when the door 3 is parallel to the side wall of the housing 1, the limit plate 13 is rotated downwards so that its end abuts against the limit block 14 on the door 3, forming a limiting support to prevent the door 3 from accidentally closing or shaking during operation.

[0018] like Figure 5As shown, the interior of the housing 1 is equipped with a drive assembly, which includes a motor 16, a bracket 15, and an electric telescopic rod 17. The bracket 15 and the electric telescopic rod 17 form a pressure regulating assembly. The frame 101 is mounted on the inner wall of the housing 1, and the bracket 15 is connected to the frame 101 via a hinge shaft, allowing the bracket 15 to swing around the hinge point. The motor 16 is mounted on the bracket 15. A traction wheel 4 is mounted on the output shaft of the motor 16. Below the traction wheel 4, an auxiliary wheel 5 is provided, which is fixed to the changing plate 2 of the housing 1 via a bearing seat. The changing plate 2 is bolted to one end face of the housing 1 for easy disassembly, maintenance, and replacement. The traction wheel 4 and the auxiliary wheel 5 together form the clamping and traction point for the optical fiber 18. To achieve clamping of optical fibers 18 with different diameters or different traction force requirements, this embodiment also includes an electric telescopic rod 17. The cylinder end of the electric telescopic rod 17 is hinged to the side wall of the housing 1 opposite to the frame 101, and the output end of its piston rod is hinged to the free end of the bracket 15. By controlling the extension or retraction of the electric telescopic rod 17, the bracket 15 is pushed or pulled to swing around its hinge point, thereby changing the distance and pressure of the motor 16 and its traction wheel 4 relative to the lower auxiliary wheel 5. This provides clamping force for optical fibers 18 of different specifications, ensuring sufficient friction for effective traction while avoiding damage to the surface of the optical fiber 18 due to excessive pressure.

[0019] like Figure 3As shown, at the input end of the traction mechanism, i.e., before the optical fiber 18 enters the traction wheel group 4, this embodiment provides an anti-backward mechanism 6, which is mounted on the changing plate 2 via the first support plate 10. The anti-backward mechanism 6 is used to guide the optical fiber 18 and ensure that it can only move forward in one direction, preventing the optical fiber 18 from backing up due to tension release during traction intervals or stops. The anti-backward mechanism 6 includes a fixed wheel 601, a one-way wheel 602, a U-shaped frame 603, and a vertical adjustment mechanism. The fixed wheel 601 is rotatably mounted on the first support plate 10 via bearings. The one-way wheel 602 is mounted at the bottom of the U-shaped frame 603. This one-way wheel 602 can only rotate freely in the traction direction, while it is locked in the opposite direction. Two guide rods 604 are connected to the top of the U-shaped frame 603. The guide rods 604 pass through the slide plate 606 and are locked and fixed above the slide plate 606 with limit bolts. A guide post 605 is also fixed on the U-shaped frame 603, which cooperates with the guide groove on the slide plate 606 to ensure that the U-shaped frame 603 does not rotate during lifting and to ensure the stability of the lifting process. The slide plate 606 is slidably connected to the vertical slide bar 607 fixed on the first support plate 10 via its back. The slide plate 606 has an elongated adjustment groove. By loosening and tightening the bolt passing through the groove, the slide plate 606 and the entire U-shaped frame 603 can be adjusted and fixed in the vertical direction. According to the diameter of the optical fiber 18, the clamping gap between the one-way wheel 602 and the lower fixed wheel 601 can be adjusted to ensure that the optical fiber 18 can be reliably clamped without being excessively squeezed. When it is necessary to insert or replace the optical fiber 18, the entire U-shaped frame 603 can be raised to expand the operating space. During operation, the optical fiber 18 is led out from the guide mechanism 7 and passes through the gap between the fixed wheel 601 and the one-way wheel 602. When the traction wheel 4 pulls the optical fiber 18 forward, the one-way wheel 602 rotates accordingly, and the optical fiber 18 passes smoothly. If the optical fiber 18 tends to retreat due to external reasons, the reverse force will lock the one-way wheel 602, which, together with the fixed wheel 601, holds the optical fiber 18, forming a mechanical self-locking mechanism to prevent it from retreating.

[0020] like Figure 4As shown, at the fiber optic cable 18 inlet of the anti-reverse mechanism 6, this embodiment also includes a guide mechanism 7, which is mounted on the form-changing plate 2 via a second support plate 11. The guide mechanism 7 is used to straighten and position the fiber optic cable 18 extending from the cable reel 8 on the door 3, ensuring that it can smoothly enter the subsequent anti-reverse mechanism 6 and traction mechanism. The guide mechanism 7 includes a pair of parallel guide plates 701, with a spacing between them maintained by a limiting post 704. The gap formed between the two plates on the horizontal plane serves as the channel for the fiber optic cable 18. Each guide plate 701 has a cable groove 7011. A set of limiting wheels, namely a first limiting wheel 702 and a second limiting wheel 703, are installed in the cable groove 7011. They are respectively mounted via a first limiting shaft 705 and a second limiting shaft 706, and are both located between the two guide plates 701. The installation positions of the first limiting shaft 705 and the second limiting shaft 706 are both adjustable by changing the vertical distance between the first limiting wheel 702 and the second limiting wheel 703 in the vertical plane. This also accommodates optical fiber 18 products with different outer diameter specifications, ensuring that all optical fibers 18 are centered and laterally limited before entering the traction mechanism, preventing the optical fiber 18 from deviating or scratching with surrounding components during traction. A limiting spacer 707 is also installed between the two guide plates 701 to ensure the distance between the two guide plates 701, providing room for the limiting wheels and optical fibers 18 to move.

[0021] The working principle of this embodiment is as follows: First, based on the diameter of the optical fiber 18 to be pulled, the pressure between the traction wheel 4 and the auxiliary wheel 5 is adjusted via the electric telescopic rod 17. Simultaneously, the gap between the one-way wheel 602 and the fixed wheel 601 is adjusted via the vertical adjustment mechanism of the anti-backward mechanism 6. The distance between the two limiting wheels in the guide mechanism 7 is also adjusted according to the outer diameter of the optical fiber 18. Then, the optical fiber 18 is led out from the reel 8 and sequentially passes between the limiting wheels of the guide mechanism 7 and between the fixed wheel 601 and the one-way wheel 602 of the anti-backward mechanism 6, finally embedding itself in the clamping area formed by the traction wheel 4 and the auxiliary wheel 5. The motor 16 is started, driving the traction wheel 4 to rotate, which pulls the optical fiber 18 forward continuously using friction. During this process, the guide mechanism 7 ensures that the optical fiber 18 remains centered and does not wobble; the one-way structure of the anti-backward mechanism 6 prevents backlash; and the electric telescopic rod 17 ensures stable and continuous traction pressure.

[0022] It will be apparent to those skilled in the art that this solution is not limited to the details of the exemplary embodiments described above, and that this solution can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
