Description

Technical Field

[0001] The utility model relates to the field of communications, in particular to an optical cable fitting for overhead lines. Background Art

[0002] Optical cable fittings are metal accessories designed for optical fiber communications. They play a key role in overhead optical cable projects for power transmission lines. With the development of telecommunication networks, optical fiber has become increasingly important as a high-speed transmission medium, and optical cable fittings are an important component to ensure that the mechanical and optical properties of optical fiber are not damaged under various environmental conditions. These fittings must be able to withstand the challenges of the natural environment, such as strong winds, ice and snow, temperature changes, etc., while protecting the optical cable from physical damage such as squeezing, stretching or twisting.

[0003] During use, the optical cable fittings for fixing the optical cable need to be fixed on the pole for use. When the fittings clamp the cables, the cables are of different types and have different diameters. Therefore, some optical cable fittings are mostly fixed in one piece and can only clamp optical cables of one size. For this reason, the existing optical cable fittings cannot clamp optical cables of different diameters. For this reason, we propose an optical cable fitting for overhead lines.

[0026] A rotation adjustment component is installed on the top of the optical cable fitting installation plate 1 and is used to adjust the distance between the upper arc plate 3 and the lower arc plate 5;

[0027] The anti-reversal component is sleeved on the rotation adjustment component to prevent the lower arc plate 5 from reversing the rotation adjustment component due to the gravity of the optical cable.

[0028] The two groups of main rods 4 are slidably sleeved with square plates 15 near the bottom, and the two groups of square plates 15 are respectively fixedly connected to the two end positions of the lower arc plate 5. The threaded screw 8 drives the rotating shaft 10 to rotate on the optical cable hardware installation plate 1, and the threaded characteristics on the threaded screw 8 are used to make the surrounding plate 6 drive the horizontal bars 7 on both sides to move synchronously, and then the two groups of main rods 4 drive the lower arc plate 5 to move upward through the square plates 15, wherein the steel balls 16 on the main rods 4 can effectively drive the square plates 15 to move, and the optical cable can be clamped between the upper arc plate 3 and the lower arc plate 5 by adjusting the upper and lower positions of the lower arc plate 5. This structure can be suitable for optical cables of different diameters, saving the cost of different hardware required for optical cables of different sizes, and saving the time required for operators to adapt hardware to optical cables of different sizes, thereby improving certain operating efficiency.

[0029] Two groups of mutually symmetrical steel balls 16 are fixedly arranged below the corresponding square plates 15 on both sides of the main rod 4. The steel balls 16 on the two groups of main rods 4 respectively drive the two groups of square plates 15 to move upwards when the main rod 4 rises.

[0030] The top ends of the two groups of main rods 4 extend out of the top of the optical cable hardware installation plate 1 and are sleeved with cross bars 7. A surrounding plate 6 is fixedly connected between the two groups of cross bars 7. The limit plate 11 rotates synchronously with the rotating shaft 10. When the surrounding plate 6 is rotated by the threaded screw 8, the threads on the threaded screw 8 drive the main rods 4 connected to the cross bars 7 on both sides to slide upward on the optical cable hardware installation plate 1.

[0031] The rotation adjustment component includes a threaded screw 8, a screw disk 9 and a rotating shaft 10. A vertical threaded screw 8 is threadedly connected to the surrounding plate 6. The top of the threaded screw 8 is fixedly connected to the screw disk 9. The bottom of the threaded screw 8 extends out of the bottom end of the surrounding plate 6 and is fixedly connected to the rotating shaft 10 at the center of the circle. The bottom end of the rotating shaft 10 is rotatably connected to the top of the optical cable hardware installation plate 1. Then, the screw disk 9 is rotated to make the screw disk 9 drive the threaded screw 8 to rotate on the surrounding plate 6. The rotating shaft 10 rotates on the top of the optical cable hardware installation plate 1 through the self-rotation of the threaded screw 8.

[0032] The anti-reversal component includes a limit plate 11, a limit hole 12, a limit rod 13 and a side rod 14. The top of the optical cable hardware installation plate 1 corresponds to the outer ring of the rotating shaft 10 and is provided with a plurality of groups of limit holes 12 distributed in an annular shape and at equal intervals. The limit plate 11 is sleeved directly above the corresponding plurality of groups of limit holes 12 on the rotating shaft 10. A vertical limit rod 13 is slidably connected to the limit plate 11 near the edge. A side rod 14 perpendicular to the limit rod 13 is fixedly connected to the side of the limit rod 13 near the top. The bottom of the side rod 14 extends out of the limit plate The bottom end of 11 is inserted into one of the groups of limiting holes 12. When the optical cable needs to be fixed, the optical cable is first passed through between the upper arc plate 3 and the lower arc plate 5, and then the optical cable hardware mounting plate 1 is fixed through the two groups of mounting holes 2. The limiting rod 13 is pulled upward on the limiting plate 11 through the side rod 14 to make the bottom of the limiting rod 13 disengage from one of the groups of limiting holes 12. Finally, the limiting rod 13 is loosened to make the bottom of the limiting rod 13 inserted into one of the groups of limiting holes 12 to prevent the threaded screw 8 from reversing.

[0033] The upper arc plate 3 and the lower arc plate 5 are both semicircular in shape and are arranged in upper and lower mirror images. The lower arc plate 5 moves upward through two groups of square plates 15 to lift the optical cable upward on the inner wall of the lower arc plate 5 until the optical cable on the lower arc plate 5 rises to fit the inner wall of the upper arc plate 3.

[0034] Working principle: When the optical cable needs to be fixed, first pass the optical cable between the upper arc plate 3 and the lower arc plate 5, and then fix the optical cable hardware installation plate 1 through the two groups of installation holes 2, pull the limit rod 13 through the side rod 14 to slide upward on the limit plate 11, so that the bottom of the limit rod 13 is out of one of the groups of limit holes 12, and then rotate the screw disk 9 to make the screw disk 9 drive the threaded screw 8 to rotate on the surrounding plate 6, and the rotating shaft 10 rotates on the top of the optical cable hardware installation plate 1 through the self-rotation of the threaded screw 8, and the limit plate 11 rotates synchronously with the rotating shaft 10. When the surrounding plate 6 is rotated by the threaded screw 8, the threads on the threaded screw 8 drive the main rod 4 connected to the horizontal bars 7 on both sides to slide upward on the optical cable hardware installation plate 1, and the steel balls 16 on the two groups of main rods 4 respectively drive the two groups of square plates 15 to move upward through the rise of the main rods 4. The lower arc plate 5 moves upward through the two groups of square plates 15 to lift the optical cable upward on the inner wall of the lower arc plate 5 until the optical cable on the lower arc plate 5 rises and fits with the inner wall of the upper arc plate 3. At this time, relax the limit rod 13, so that the bottom of the limit rod 13 is inserted into one of the groups of limit holes 12 to prevent the threaded screw 8 from reversing.
