Description

Technical Field

[0001] This utility model belongs to the field of optical fiber equipment technology, and in particular relates to a foldable optical fiber reel. Background Technology

[0002] With the rapid development of data center construction, the Internet of Things and other fields, optical fiber has become the core medium for information transmission due to its advantages such as high bandwidth, low loss and strong anti-interference ability. Its application in various engineering and scientific research projects is becoming more and more widespread. In the production, transportation, installation and maintenance of optical fiber, optical fiber reels are an indispensable auxiliary equipment, which undertake the important functions of receiving, protecting and orderly laying the cables. Their performance directly affects the construction efficiency and operational stability of the optical fiber system.

[0003] However, traditional fiber optic reels are typically monolithic structures with a fixed and large volume. They occupy a significant amount of storage space when not in use and also take up considerable space during transportation, increasing transportation costs. Furthermore, the relatively fixed structure of traditional fiber optic reels makes it difficult to flexibly adjust the reticle's capacity. When storing optical fibers of different lengths, either the reel's excessive size causes the fibers to become loosely wound and prone to mutual friction and damage, or the reel's insufficient size cannot accommodate enough fiber length, limiting its application scenarios.

[0004] To address these issues, we offer a foldable fiber optic reel. Utility Model Content

[0005] The purpose of this invention is to provide a foldable fiber optic reel, which solves the problems of inconvenient storage and transportation of fiber optic reels and difficulty in adjusting the reel's storage space in the prior art through the cooperation of locking and adjusting components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

The locking assembly includes a fixing block, the top of which is fixedly connected to the inner reel. A slot is provided on one side of the fixing block, and an insert block is slidably connected to the inner cavity of the slot. The bottom of the insert block is slidably connected to the outer reel. A first spring is provided on the rear side of the insert block, the other side of which is fixedly connected to the outer reel. A push rod is fixedly connected to the other side of the insert block. The push rod extends through the inner cavity of the outer shaft disk and to the surface of the outer shaft disk on the other side. There are two locking components, which are symmetrically distributed on both sides of the inner cavity of the outer shaft disk to form a two-way locking, which can evenly distribute the force between the outer shaft disk and the inner shaft disk. A slide rod is slidably connected to the bottom of the push rod, and both sides of the slide rod are fixedly connected to the outer shaft disk, which can improve the stability of the push rod when moving. A support frame is provided at the bottom of the push rod. One side of the support frame is fixedly connected to the outer shaft disk, and there are two support frames, one on the surface of the outer shaft disk and the other on the surface of the inner shaft disk, which can evenly bear the pressure transmitted by the outer shaft disk and the inner shaft disk.

[0008] The present invention is further configured such that the adjustment component includes a connecting plate, the surface of the connecting plate is slidably connected to the inner shaft disk, a locking block is fixedly connected to one side of the connecting plate, an mounting plate is slidably connected to one side of the locking block, a second spring is fixedly connected to the top of the mounting plate, an adjustment groove is provided on the top of the inner cavity of the outer shaft disk, the top of the locking block is slidably connected to the adjustment groove, and there are multiple adjustment grooves, so that the operator can adjust the extension length of the inner shaft disk in multiple levels according to the needs.

[0009] The present invention is further configured such that the inner cavity of the outer shaft disk has a slot, and a slide block is slidably connected to the inner cavity of the slot. One side of the slide block is fixedly connected to the inner shaft disk, and the other side of the slide block is fixedly connected to a fixing block. The slot and the slide block can limit the range of motion and operation mode of the inner shaft disk.

[0010] The present invention is further configured such that a limiting groove is provided at the bottom of the inner cavity of the outer shaft disk, a limiting block is slidably connected to the inner cavity of the limiting groove, and the top of the limiting block is fixedly connected to the insert block. The setting of the limiting groove and the limiting block provides precise guidance and limitation for the locking block.

[0011] The present invention is further configured such that a handle is provided on the top of the push rod, and one side of the handle is fixedly connected to the outer shaft disc. The handle serves as a dedicated lifting component, providing a stable and comfortable point of force for transporting the reel.

[0012] The present invention is further configured such that a fixing rod is fixedly connected to one side of the inner cavity of the inner shaft disk, the surface of the fixing rod is slidably connected to the connecting plate, and there are two fixing rods, which are symmetrically distributed on both sides of the connecting plate, thereby improving the stability of the connecting plate when it moves.

[0013] The present invention is further configured such that a support rod is fixedly connected to the bottom of the card block, the bottom of the support rod is slidably connected to the mounting plate, and the support rod is located in the inner cavity of the second spring, which can effectively prevent the second spring from twisting and deforming during operation.

[0014] The present invention is further configured such that sliding grooves are provided on both sides of the inner cavity of the mounting plate, and a slider is slidably connected to the inner cavity of the sliding groove. The other side of the slider is fixedly connected to the card block. There are two sliding grooves and two sliders, which are symmetrically distributed on both sides of the card block, thereby limiting the range of motion of the card block.

[0015] The present invention has the following beneficial effects.

[0016] 1. After the outer and inner shaft discs are retracted and stored, the first spring pushes the insert block to tightly insert into the slot of the fixing block, forming a firm mechanical locking structure. During transportation, even if encountering complex external force environments such as bumps and vibrations, the tight cooperation between the insert block and the slot can firmly restrict the relative movement of the outer and inner shaft discs, preventing the outer shaft disc from automatically extending. Moreover, this locking component can ensure that the probability of the outer shaft disc accidentally extending under severe vibration is reduced to almost zero, greatly ensuring the stability of the coil storage state and avoiding the risk of optical fiber entanglement or even damage caused by coil extension.

[0017] 2. The adjustment component of this utility model achieves precise fine-tuning of the outer shaft disk position through the sliding connection between the connecting plate and the inner shaft disk, and the sliding of the locking block in the adjustment groove. When it is necessary to change the spool's accommodating space to accommodate optical fibers of different lengths, press the connecting plate and pull out the inner shaft disk. After adjustment, release the connecting plate, and the locking block enters the slot to lock the movable position of the inner shaft disk. According to actual needs, the operator can adjust the spool to a suitable size to ensure that the optical fiber is wound tightly and evenly, avoiding the optical fiber from becoming loose or overly tight due to improper spool size, effectively improving the standardization and safety of optical fiber storage and laying.
