Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber installation technology, and in particular to an optical fiber through-wall traction device. Background Technology
[0002] With the large-scale deployment of fiber optic communication networks, the demand for fiber optic cabling inside and outside buildings and between different areas is increasing daily. In fiber optic laying projects, wall penetration is one of the most common and challenging aspects. Traditional methods of fiber optic cable pulling rely primarily on manual operation. Workers typically use traction ropes or wires as guides, along with lubricants, to assist the fiber optic cable through pre-embedded conduits in the wall. However, this method has many technical limitations in practical applications. Uneven tension or angular deviations during wall penetration can easily damage the fiber core, affecting transmission performance. Manual pulling makes it difficult to precisely control the magnitude and direction of force, especially when passing through walls over long distances or along curved paths. When there are foreign objects, burrs, or insufficient turning radii in the wall conduits, traditional pulling methods can easily cause fiber optic jamming. Statistics show that approximately 30% of fiber optic laying failures originate from physical damage during wall penetration. Therefore, we have redesigned a fiber optic wall-penetrating pulling device. Utility Model Content

[0023] Working principle:
[0024] By installing a braided mesh tube 2 on one side of the steel wire ring 1, the braided mesh tube 2 is wound around the surface of the steel wire ring 1, and then the braided mesh tube 2 is squeezed and locked by 3 to ensure the stability of the connection between the steel wire ring 1 and the braided mesh tube 2. Then, it is connected to the steel wire ring 1 through the lower traction tube connector 5, and the traction is achieved by using the connection hole 7 on the upper traction ring connector 6. The other end of the braided mesh tube 2 is directly connected to the fiber optic puller. For the traction control of fiber optic wall penetration, it ensures the stable wall penetration installation of the fiber optic, increases the installation efficiency and quality of the fiber optic, and avoids the problem of fiber optic damage during installation. The protective heat shrink tube 4 is installed after the connection pressure ring 3 is installed, which wraps and seals the connection pressure ring 3 and improves the stability of the connection position of the connection pressure ring 3. The upper traction ring connector 6 and the lower traction tube connector 5 can rotate to achieve different rotation angles and improve the flexibility of the device.
[0025] By setting the first connecting ring 8 to slide on the wire ring 1, and simultaneously the second connecting ring 13 to slide on the wire ring 1, the first mesh tube limiting plate 9 and the second mesh tube limiting plate 14 are connected. At this time, the pin plate 16 is inserted into the pin groove 11. By aligning the second locking connection hole 17 and the first locking connection hole 12, fixing screws are installed inside the second locking connection hole 17 and the first locking connection hole 12. For a stable connection between the first mesh tube limiting plate 9 and the second connecting ring 13, the first mesh tube limiting chamber 10 inside the first mesh tube limiting plate 9 and the second mesh tube limiting plate 14 inside the second connecting ring 13 wrap around the braided mesh tube 2 wrapped on the wire ring 1. This improves the stability of the connection of the braided mesh tube 2 and prevents the braided mesh tube 2 from breaking during traction, thus increasing its service life.
