Description

Technical Field

[0001] This utility model relates to the field of optical fiber cable technology, specifically to an optical fiber cable take-up and lay-out frame. Background Technology

[0002] When rapidly establishing a network at an urban emergency site, fiber optic cable take-up and lay-out devices are required. Currently, the most widely used fiber optic communication equipment on the market consists of ordinary multi-core optical fibers or cables. A few single-core optical fiber communication devices are armored, which provides strong resistance to pressure, but are also heavy and unsuitable for single-person transport. Furthermore, the winding wheels of existing take-up and lay-out mechanisms are prone to causing fiber optic cables to accumulate and become tangled during the take-up and lay-out process, leading to cable knots, breakage, or signal attenuation, affecting communication quality and construction efficiency. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, this application provides a fiber optic cable take-up and delivery frame.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a fiber optic cable take-up and unwinding frame, comprising: a support; a winding mechanism, the winding mechanism including a winding roller and baffles, the winding roller being rotatably mounted on the support, and two baffles being disposed at both ends of the winding roller, forming a winding space between the two baffles; and a pressing mechanism for pressing the cable onto the winding roller.

[0005] In some embodiments of this utility model, the above-mentioned pressing mechanism includes a crossbeam and a counterweight block disposed on the support. The counterweight block is lifted and disposed on the crossbeam and can abut against the winding roller.

[0006] In some embodiments of this utility model, a telescopic rod is provided between the counterweight block and the crossbeam.

[0007] In some embodiments of this utility model, the above also includes a transportation mechanism, which includes a base and drive wheels, with a bracket disposed on the base and drive wheels disposed at the four corners of the base.

[0008] In some embodiments of this utility model, a tie rod is provided on the base, and the tie rod is a telescopic structure.

[0009] In some embodiments of this utility model, the telescopic structure includes a vertical tube and a sliding rod. One end of the vertical tube is fixedly mounted on the base, and the sliding rod is slidably mounted inside the vertical tube. The vertical tube and the sliding rod are connected by a limiting member.

[0010] In some embodiments of this utility model, the limiting member includes a spring and a limiting post. The spring is disposed inside the slide rod, and the limiting post is disposed at the end of the spring. Limiting holes are evenly spaced on the vertical cylinder along the central axis of the slide rod. The spring can push the limiting post into any limiting hole.

[0011] In some embodiments of this utility model, the drive wheel is a universal wheel, and a locking element is provided on the universal wheel.

[0012] Beneficial effects:

[0013] 1. The cable pressing mechanism presses the cable onto the winding roller during the winding process, dynamically pressing the cable to reduce cable slack and tangling. The pressing mechanism provides constant pressure to prevent the cable from piling up or crossing due to slack during winding. The cable is tightly pressed against the surface of the winding roller, avoiding tangling or knotting caused by excessive gaps, thus reducing the probability of tangling. The pressing design can buffer the instantaneous impact force during winding and reducing fiber micro-bending loss. Attached Figure Description

[0026] Please refer to Figures 1-4 This embodiment provides a fiber optic cable take-up and unwinding frame, including: a support 1; a winding mechanism, which includes a winding roller 2 and baffles 3, the winding roller 2 being rotatably mounted on the support 1, and two baffles 3 being disposed at both ends of the winding roller 2, forming a winding space 4 between the two baffles 3; and a pressing mechanism, which is used to press the cable onto the winding roller 2.

[0027] In this embodiment, the bracket 1 is used to install the cable winding mechanism and the cable pressing mechanism, so that the two work together to achieve orderly cable winding and unwinding operations.

[0028] In this embodiment, the winding roller 2 is used to wind up the cable, facilitating the cable's storage and release. The pressing mechanism presses the cable onto the winding roller 2 during the winding and releasing process, dynamically pressing the cable to reduce slack and tangling. The pressing mechanism provides constant pressure to prevent the cable from piling up or crossing due to slack during the winding and releasing process.

[0029] Please refer to Figures 1-3 In some embodiments of this example, the above-mentioned pressing mechanism includes a crossbeam 5 and a counterweight block 6 disposed on the support 1. The counterweight block 6 is elliptically disposed on the crossbeam 5 and can abut against the winding roller 2.

[0030] In this embodiment, the above-mentioned pressing mechanism consists of a crossbeam 5 fixed to the bracket 1 and a counterweight block 6. The counterweight block 6 is installed below the crossbeam 5 through a lifting structure, and the counterweight block 6 can move freely in the vertical direction.

[0031] During use, the aforementioned counterweight block 6 presses the cable downwards under its own weight, making it tightly adhere to the surface of the winding roller 2. During winding, the cable is fixed to the winding roller 2 by the counterweight block 6 and completes the winding process as the winding roller 2 rotates.

[0032] It should be noted that by utilizing the gravity of the counterweight block 6 itself, there is no need for a complex drive device; the wire pressing is achieved solely by gravity, resulting in a low failure rate and reduced maintenance costs.

[0033] Please refer to Figures 1-3 In some embodiments of this example, a telescopic rod 7 is provided between the counterweight block 6 and the crossbeam 5.

[0034] In this embodiment, the telescopic rod 7 provides a path for the longitudinal movement of the counterweight block 6. The telescopic rod 7 is composed of a sleeve with a rectangular cross section and a sliding rod, which can effectively ensure that the counterweight block 6 is always parallel to the central axis of the winding roller 2.

[0035] Please refer to Figures 1-3 In some embodiments of this example, the above also includes a transport mechanism, which includes a base 8 and drive wheels 9. The bracket 1 is disposed on the base 8, and the drive wheels 9 are disposed at the four corners of the base 8.

[0036] In this embodiment, the bracket 1 is fixed on the base 8, and drive wheels 9 are installed at the four corners of the bottom of the base 8, so that the equipment can be moved by manual pushing or by motor driving.

[0037] When the equipment needs to be moved, the user pushes the base 8 with the lever, and the drive wheel 9 rolls to reduce friction and achieve rapid deployment.

[0038] Please refer to Figures 1-3 In some embodiments of this example, a tie rod is provided on the base 8, and the tie rod is a telescopic structure.

[0039] In this embodiment, the aforementioned pull rod is a telescopic structure, consisting of a vertical cylinder 10 and a sliding rod 11, with its length fixed by a limiting member. When the user pulls the sliding rod 11 to the desired height, the limiting member automatically locks the position; when storage is required, pressing the limiting member releases the sliding rod 11. The pull rod height is adjustable to accommodate users of different heights, reducing fatigue in the waist or shoulders. The telescopic design allows the pull rod to retract to its shortest state, facilitating transportation or storage. The pull rod is rigidly connected to the base 8, preventing the equipment from tipping over during movement and improving safety.

[0040] Please refer to Figures 1-3 In some embodiments of this example, the telescopic structure includes a vertical cylinder 10 and a sliding rod 11. One end of the vertical cylinder 10 is fixedly mounted on the base 8, and the sliding rod 11 is slidably mounted inside the vertical cylinder 10. The vertical cylinder 10 and the sliding rod 11 are connected by a limiting member.

[0041] In this embodiment, the slide rod 11 can slide freely along the direction of the vertical cylinder 10. The length of the entire pull rod can be adjusted by the relative length of the slide rod 11 extending into the vertical cylinder 10, thereby adapting to users of different heights and reducing fatigue in the waist or shoulders. The limiting post 13 is installed inside the slide rod 11 to fix the adjusted length of the pull rod.

[0042] Please refer to Figure 2 In some embodiments of this example, the limiting member includes a spring 12 and a limiting post 13. The spring 12 is disposed inside the slide rod 11, and the limiting post 13 is disposed at the end of the spring 12. Limiting holes 14 are evenly spaced along the central axis of the slide rod 11 on the vertical cylinder 10. The spring 12 can push the limiting post 13 into any limiting hole 14.

[0043] In this embodiment, the aforementioned limiting post 13 is installed inside the slide rod 11 and connected to the inner wall of the slide rod 11 via a spring 12; limiting holes 14 are evenly distributed along the axial direction on the vertical cylinder 10. The spring 12 pushes the limiting post 13 into the limiting hole 14 of the vertical cylinder 10, thereby fixing the slide rod 11; when adjustment is required, the limiting post 13 is pressed to compress the spring 12, causing it to disengage from the limiting hole 14. The limiting holes 14 are evenly distributed to ensure that the pull rod remains horizontal after each adjustment, preventing the equipment from tilting. Preferably, the limiting post 13 and the limiting hole 14 are made of high-strength steel.

[0044] Please refer to Figures 1-3 In some embodiments of this example, the drive wheel 9 is a swivel wheel, and a locking element 15 is provided on the swivel wheel.

[0045] In this embodiment, the drive wheel 9 is a swivel wheel with a locking element 15 installed on it. In the moving mode, the locking element 15 is released, allowing the swivel wheel to roll freely; in the stationary mode, pressing the brake pedal or rotating the knob engages the locking element 15 with the wheel's friction pad, preventing rotation. The swivel wheel allows the device to turn on the spot, enabling flexible deployment in confined spaces. The locking element 15 can instantly secure the device, preventing cable breakage or tangling during cable rewinding or unwinding due to device movement.

[0046] Please refer to Figures 1-3 In this embodiment, a drive wrench 16 for winding is provided at any end of the winding roller 2, and a rectangular block 17 is provided at the end of the winding roller 2. The drive wrench 16, which is detachably provided on the rectangular block 17, has a rectangular groove, so that the two can be adapted to rotate the winding roller 2.

[0047] When the cable is unloaded, the cable is pulled and the winding roller 2 rotates. The cable on the same plane is gradually pulled out. Due to its own weight, the counterweight block 6 always abuts against the cable on the outermost surface. When the cable on the same plane is unloaded and enters the layer closer to the surface of the winding roller, the counterweight block 6 moves downward under its own weight and always remains abutting against the outer surface of the cable.

[0048] During the winding process, due to the action of the counterweight block 6, the cable gradually fills the same layer. When the winding on the same plane is completed, it pushes the counterweight block 6 upward, and the cables are stacked up in sequence, which can prevent the cables from piling up.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
