Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic patch cord fixing devices, specifically a fiber optic patch cord fixing device with adaptive tension adjustment. Background Technology
[0002] In the construction and maintenance of fiber optic communication systems, the stable fixation of fiber optic patch cords is fundamental to ensuring efficient signal transmission. Currently, fiber optic patch cord fixation mostly relies on traditional clips, straps, or fixed clamping structures, which have significant limitations in practical applications.
[0003] From a tension adjustment perspective, existing devices generally lack dynamic adaptability. Clip-on structures have a fixed clamping force; if the clips are too tight during installation, they can easily squeeze the outer sheath of the fiber optic patch cord, even causing micro-bending of the internal fiber, affecting optical signal transmission efficiency. If the clips are too loose, they cannot withstand displacement caused by equipment vibration or slight cable pulling, leading to loose patch cords and poor contact. While strap-on structures allow for manual tension adjustment, the adjustment precision is poor, and over long-term use, the straps are prone to elasticity loss due to aging, gradually causing tension imbalance. This requires frequent manual inspection and adjustment, increasing maintenance costs. When the ambient temperature changes drastically, the fiber optic patch cord will change length due to thermal expansion and contraction. Existing fixing devices cannot automatically adjust to tension fluctuations, easily causing the patch cord to be in an over-tensioned or slack state for extended periods, shortening its lifespan.
[0004] Traditional fixing devices lack versatility in adapting to patch cords of different thicknesses. Most clamping structures have fixed dimensions and can only accommodate a single specification of fiber optic patch cord. However, in actual communication scenarios, it is often necessary to deploy patch cords of different diameters simultaneously. In this case, multiple models of fixing devices are required, which not only increases procurement costs but also leads to messy cabling scenarios and makes unified management difficult. Summary of the Invention
[0005] To solve the above-mentioned technical problems, this utility model provides an adaptive tension-adjustable fiber optic patch cord fixing device.
[0006] This utility model provides an adaptive tension-adjustable fiber optic patch cord fixing device, including a fixed base and a movable base disposed on one side of the fixed base. Lower positioning arc blocks are fixedly connected to the surfaces of both the fixed base and the movable base. An upper positioning arc block is hinged to the top of the lower positioning arc block via a hinge. A pressing mechanism is threadedly connected to the surface of the upper positioning arc block. An adaptive mechanism is disposed in the middle of the fixed base and the movable base.
[0007] The pressing mechanism includes a threaded rod threaded to the surface of the upper positioning arc block, the output end of the threaded rod is rotatably connected to a rotating shaft, and a protrusion is fixedly connected to one side of the rotating shaft;
[0008] The adaptive mechanism includes a fixed cylinder disposed in the middle of the fixed seat and the movable seat. A support spring is fixedly connected inside the fixed cylinder, and a telescopic rod is fixedly connected to the end of the support spring.
[0009] Preferably, the telescopic rod is slidably connected inside the fixed cylinder, and one side of the telescopic rod is fixedly connected to one side of the movable seat, so that the telescopic rod can be extended or retracted by pulling the support spring.
[0010] Preferably, the bottom of the fixed seat is threadedly connected to a base, and a telescopic block is fixedly connected to one side of the fixed seat. The telescopic block facilitates the support of the fixed seat and the movable seat.
[0011] Preferably, the bottom of the movable seat is provided with a sliding groove, and a limiting slider is slidably connected inside the sliding groove, which facilitates the limiting and fixing of the movable seat.
[0012] Preferably, the movable seat has a limiting hole inside, which is adapted to the telescopic block, and the positioning hole facilitates the installation of the telescopic block.
[0013] Preferably, mounting holes are provided on both sides of the surface of the telescopic block, and a scale plate is installed inside the mounting holes. The scale plate facilitates observation of whether the tension of the jumper wire changes.
[0014] Preferably, both the upper and lower positioning arc blocks have threaded holes on their surfaces, and positioning bolts are threaded into the internal threads of the threaded holes. The positioning bolts facilitate the fixing of the upper and lower positioning arc blocks.
[0015] Compared with related technologies, the present invention provides the following beneficial effects:
[0016] 1. Through the adaptive mechanism, when the fiber optic patch cord is pulled by external force or deformed due to temperature changes, causing increased tension, the fiber optic patch cord drives the bottom movable seat to move on the limiting slider set on the base surface, compressing the support spring. The reverse elastic force generated by the support spring acts on the movable seat, gradually offsetting the external force and reducing the tension of the fiber optic patch cord. Similarly, when the tension of the fiber optic patch cord decreases, the support spring resets under its own elastic force, pushing the movable seat to move closer to the fiber optic patch cord, maintaining appropriate tension on the fiber optic patch cord, ensuring that it is always in a stable fixed state, realizing adaptive tension adjustment, avoiding damage to the fiber optic patch cord due to excessive tension or loosening due to insufficient tension, effectively ensuring the safety of use and communication stability of the fiber optic patch cord.
[0017] 2. With the pressing mechanism in place, the fiber optic patch cord is positioned on the lower positioning block surface during use. Then, the upper positioning block is rotated and fixed at the end with a positioning bolt. At this point, the threaded rod connected to the upper positioning block surface can be rotated. The threaded rod drives the bottom shaft to rotate, thereby adjusting the position of the protrusion on one side of the shaft until it moves to the surface of the fiber optic patch cord, pressing and fixing the fiber optic patch cord. This achieves the effect of installing and fixing fiber optic patch cords of different thicknesses, improving the versatility of the equipment during use. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please refer to the following: Figures 1 to 4 An adaptive tension-adjustable fiber optic patch cord fixing device includes a fixed base 1 and a movable base 2 disposed on one side of the fixed base 1. A lower positioning arc block 3 is fixedly connected to the surface of both the fixed base 1 and the movable base 2. An upper positioning arc block 4 is hinged to the top of the lower positioning arc block 3. A pressing mechanism 5 is threadedly connected to the surface of the upper positioning arc block 4. The pressing mechanism 5 enables the installation and fixing of fiber optic patch cords of different thicknesses, improving the versatility of the device during use. An adaptive mechanism 6 is provided in the middle of the fixed base 1 and the movable base 2. The adaptive mechanism 6 prevents the fiber optic patch cord from being damaged due to excessive tension or loosening due to insufficient tension, effectively ensuring the safety of use and communication stability of the fiber optic patch cord.
[0025] The pressing mechanism 5 includes a threaded rod 501 threaded to the surface of the upper positioning arc block 4. The threaded rod 501 facilitates the movement of the protrusion 503. The output end of the threaded rod 501 is rotatably connected to a rotating shaft 502. A protrusion 503 is fixedly connected to one side of the rotating shaft 502. The protrusion 503 facilitates pressing and fixing the fiber optic patch cord.
[0026] The adaptive mechanism 6 includes a fixed cylinder 601 located in the middle of the fixed base 1 and the movable base 2. A support spring 602 is fixedly connected inside the fixed cylinder 601. The support spring 602 facilitates adaptive tension adjustment. A telescopic rod 603 is fixedly connected to the end of the support spring 602. The telescopic rod 603 facilitates pulling the support spring 602.
[0027] Of particular note is that the telescopic rod 603 is slidably connected to the inside of the fixed cylinder 601, and one side of the telescopic rod 603 is fixedly connected to one side of the movable seat 2; the bottom of the fixed seat 1 is threadedly connected to the base 7, and one side of the fixed seat 1 is fixedly connected to the telescopic block 8, which facilitates the support of the fixed seat 1 and the movable seat 2.
[0028] In addition, a sliding groove is provided at the bottom of the movable seat 2, and a limiting slider 9 is slidably connected inside the sliding groove; a limiting hole is provided inside the movable seat 2, which is adapted to the telescopic block 8, and the limiting slider 9 facilitates the limiting and fixing of the movable seat 2.
[0029] The telescopic block 8 has mounting holes on both sides of its surface. A scale plate 10 is installed inside the mounting holes. The scale plate 10 is used to observe whether the tension of the jumper wire changes. The upper positioning arc block 4 and the lower positioning arc block 3 have threaded holes on their surfaces. The threaded holes are connected to positioning bolts 11. The positioning bolts 11 are used to fix the upper positioning arc block 4 and the lower positioning arc block 3.
[0030] When the fiber optic patch cord is pulled by an external force or deformed due to temperature changes, causing the tension to increase, the fiber optic patch cord drives the bottom movable seat 2 to move on the limiting slider 9 set on the surface of the base 7, compressing the support spring 602. The reverse elastic force generated by the support spring 602 acts on the movable seat 2, gradually offsetting the external force and reducing the tension of the fiber optic patch cord. Similarly, when the tension of the fiber optic patch cord decreases, the support spring 602 resets under its own elastic force, pushing the movable seat 2 to move closer to the fiber optic patch cord, maintaining a moderate tension on the fiber optic patch cord, ensuring that it is always in a stable fixed state, and realizing adaptive adjustment of tension.
[0031] When in use, place the fiber optic patch cord into the surface of the lower positioning arc block 3, then rotate the upper positioning arc block 4 and fix it at the end with the positioning bolt 11. At this time, the threaded rod 501 connected to the thread on the surface of the upper positioning arc block 4 can be rotated. The threaded rod 501 drives the bottom rotating shaft 502 to rotate, thereby adjusting the position of the protrusion 503 on one side of the rotating shaft 502 until the protrusion 503 moves to the surface of the fiber optic patch cord and presses down to fix the fiber optic patch cord.
