Description

Technical Field

[0001] This utility model relates to the field of optical fiber pigtail storage technology, specifically to an optical fiber pigtail detachable telescopic coil device. Background Technology

[0002] A fiber optic pigtail is a fiber optic cable with a fiber optic connector at one end and a broken fiber optic core at the other end. It is used to connect fiber optic cables to fiber optic transceivers or other equipment. In actual use, a certain length of fiber optic pigtail is usually reserved. In order to avoid damage to this section of fiber optic pigtail, a corresponding fiber coiling device is needed to wind and store it.

[0003] A search revealed that an existing patent (publication number: CN206161939U) discloses a detachable telescopic fiber coiling device for optical fiber pigtails. The device includes a rectangular base plate and a detachable storage tray consisting of a frame connecting the four sides of the base plate. The outline of the detachable storage tray is identical to the plug-in module in the ODF unit box. Optical fiber pigtail inlets and outlets are provided on the side frame of the detachable storage tray. A telescopic fiber coiling mechanism is provided on the base plate. The telescopic fiber coiling mechanism consists of a guide rod fixedly connected to the base plate, two fiber-winding arcs slidably connected to the two ends of the guide rod with opposite openings, and a telescopic spring sleeved on the guide rod, with each end connected to one of the two fiber-winding arcs. A groove is provided on the outer wall of the fiber-winding arc. The detachable storage tray can be directly plugged into the frame. The optical fiber pigtail is coiled on the telescopic fiber coiling mechanism, which not only keeps the wiring neat but also effectively protects the pigtail from mechanical damage. The telescopic fiber coiling mechanism also keeps the optical fiber pigtail taut, further preventing mechanical damage.

[0004] However, in the above solution, it is inconvenient to compress the fiber optic pigtail after it has been wound and coiled. This allows the fiber optic pigtail to slide up and down after being wound by the telescopic coiling mechanism, which is not conducive to the stable winding and coiling of the fiber optic pigtail, resulting in inconvenience in its use.

[0005] In view of this, the present invention proposes a fiber optic cable pigtail detachable telescopic coil device. Utility Model Content

[0027] In this embodiment, the rubber pad 203 is used to achieve flexible pressing between the bottom end of the pressing plate 204 and the top end of the wound optical fiber pigtail.

[0028] In a further preferred embodiment of the present invention, a sliding structure is formed between the surfaces of the slider 10 and the slider 7, and the slider 7 is cross-shaped.

[0029] In this embodiment, a cross-shaped slider 10 is used to improve the smoothness of the slider 10 sliding on the surface of the slider 7. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the optical fiber pigtail split telescopic coil device provided by this utility model is, for example... Figures 1 to 5 As shown: The fixing component 4 includes: a fixing block 401 fixedly connected to the middle position of both sides of the top of the fixing frame 6, a fixing nut 403 movably connected to the top of the fixing block 401, and a fixing bolt 402 that passes through the fixing block 401 fixedly connected to the bottom of the fixing nut 403; and a bolt hole 405 opened in the bottom wall of the housing 1, with the inside of the bolt hole 405 and the bottom of the fixing bolt 402 forming a threaded engagement structure.

[0031] In this embodiment, by rotating the fixing nut 403, the fixing bolt 402 is rotated until it is completely disengaged from the bolt hole 405. Then, the fixing bracket 6 can be pulled upward to disassemble the fixing bracket 6 from the fixing groove 9. During installation, the fixing bracket 6 is snapped into the fixing groove 9, and the fixing bolt 402 is tightened into the bolt hole 405 to achieve a secure snap-fit ​​installation of the fixing bracket 6.

[0032] In a further preferred embodiment of the present invention, the fixing block 401 is inverted L-shaped, and the upper end of the inner wall of the fixing block 401 and the inner wall of the fixing groove 9 form an engaging structure.

[0033] In this embodiment, the engagement between the inverted L-shaped fixing block 401 and the inside of the fixing groove 9 further improves the firmness and stability of the fixing frame 6 during engagement.

[0034] In a further preferred embodiment of the present invention, the surface of the fixing nut 403 is provided with anti-slip textures 404 at equal angles, and the shape of the anti-slip textures 404 is arc-shaped.

[0036] In a further preferred embodiment of this utility model, the interior of the fixing frame 6 and the fixing groove 9 form a locking structure, and the shape of the fixing frame 6 is a U-shape.

[0037] The working principle of this utility model is as follows: First, the mounting feet 3 and the housing 1 are installed and fixed in a suitable position using external bolts, etc. Then, the optical fiber pigtail is inserted from the notch at one end of the housing 1 and wound around the two guide seats 5 in sequence. At the same time, the elastic force of the return spring 8 is used to make the slider 10 slide on the surface of the slide rod 7 and drive the guide seats 5 to slide. Then, the optical fiber pigtail can be telescopically clamped and wound through the two guide seats 5. Then, the rotating handle 201 is rotated to drive the threaded rod 205 to rotate. The threaded engagement between the threaded rod 205 and the threaded block 202 causes the threaded block 202 to descend, which in turn causes the pressure plate 204 to descend. This allows the rubber pad 203 to flexibly press the top of the optical fiber pigtail wound inside the guide seats 5, thereby achieving the pressing and fixing of the wound optical fiber pigtail. Meanwhile, when individual mounting brackets 6 or components mounted on them are damaged, or when disassembly and maintenance are required, the fixing nut 403 can be rotated to rotate the fixing bolt 402 until it is completely disengaged from the bolt hole 405. Then, the mounting bracket 6 can be pulled upwards to disassemble the mounting bracket 6 from the fixing groove 9. During installation, the mounting bracket 6 is snapped into the fixing groove 9, and the fixing bolt 402 is tightened into the bolt hole 405 to achieve a secure snap-fit ​​installation of the mounting bracket 6. Thus, the overall disassembly and maintenance difficulty is reduced through modular independent disassembly and assembly.
