Description

Technical Field

[0001] This utility model relates to a QCW fiber roll output length control device, and particularly to a QCW fiber transmission assembly with a structure for controlling the output length. Background Technology

[0002] During QCW fiber installation, the QCW fiber roll is often pulled out according to the installation requirements and the approximate length of material needed. After being pulled out to the approximate length, it is cut. Therefore, it is necessary to design a structure that can pull out the QCW fiber line to the approximate length range according to the length requirements of the QCW fiber before cutting, so as to more accurately control the pulled-out length and prevent the operation trouble caused by pulling out too long and having to re-roll the material, or the material waste caused by cutting it too long or too short after pulling it out.

[0003] Therefore, the existing QCW fiber roll output length control device needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a QCW fiber optic transmission assembly with a controlled output length structure, which can better meet the length requirements of QCW fiber optic cables, control the amount of material pulled out before cutting, and prevent situations where the material is wasted due to excessive length or cannot meet installation requirements due to insufficient length.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A QCW fiber optic transmission assembly with a controlled output length structure includes a support frame, a QCW fiber optic spool assembly mounted on the support frame, a vortex guide groove mounted on the support frame, a radially movable block mounted on the QCW fiber optic spool assembly, a spring structure within the radially movable block capable of pressing the radially movable block inward, an axially elastic limiting shaft within the radially movable block, the axially elastic limiting shaft being movably mounted within the vortex guide groove, and a limiting baffle adjustment structure on the support frame for radially penetrating the vortex guide groove.

[0007] Furthermore, the QCW fiber optic roll assembly includes a fixed shaft disposed on the bracket, a roll is rotatably mounted on the fixed shaft, and a winding groove is provided on the outer circumference of the roll.

[0008] Furthermore, the bracket is provided with a rear fixing surface, and the vortex guide groove is provided on the rear fixing surface and is concentrically arranged with the fixing shaft.

[0009] Furthermore, the radial movable block includes a radial groove disposed on the end face of the drum, and a radial slider is movably disposed in the radial groove.

[0010] Furthermore, the axial elastic limiting shaft includes an axial cavity and an axial hole disposed in the radial slider, a movable limiting shaft is disposed in the axial hole, an elastic clamping structure is disposed between the movable limiting shaft and the axial cavity, and the movable limiting shaft is movably installed in the vortex guide groove.

[0011] Furthermore, the limiting baffle adjustment structure includes a radial slot provided on the rear fixed surface, and a limiting baffle is movably disposed within the radial slot.

[0012] Furthermore, the surface of the limiting baffle is provided with a scale.

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] This invention addresses the shortcomings of existing QCW fiber roll output control. Through its structural design, it offers the following advantages: by pulling out the limiting baffle to adjust the radial position of the structure, the number of rotations of the axial elastic limiting shaft is controlled, achieving approximate control of the output length. This reduces material waste and prevents situations where the QCW fiber roll is pulled out too short, failing to meet installation requirements, or pulled out too long, resulting in material waste and operational inconvenience due to rewinding. It achieves QCW fiber length control for output, and its simple structure makes it easy to use. Attached Figure Description
