[0002] Fiber optic fault location devices are used to detect and locate fault points in fiber optic networks. They obtain information such as fiber loss, length, splice loss, and break point location by injecting light pulses into the fiber and then measuring the time and intensity of reflected and scattered light. Using the device for precise fault location can quickly repair fiber optic faults, reduce network downtime, and ensure the continuity and stability of communication services.

[0003] However, in the application of fiber optic fault location devices, technicians often operate the devices by hand or placing them on the ground in unsuitable positions to detect and locate fiber optic faults. This is inconvenient and can easily affect the stability of the connection between the fiber optic cable and the equipment, thus affecting the accuracy of the detection results. There are technical problems with the inability to stably support and place the equipment or adjust the operating angle and height so that technicians can quickly and effectively carry out fiber optic fault location and detection work.

[0010] Furthermore, a through nut is fitted into one side of the hinge seat, and a tightening bolt is inserted between the other side of the hinge seat and the top end of the first adjusting rod and the bottom end of the second adjusting rod. One side of the tightening bolt passes through the interior of the through nut, and the bottom end of the first adjusting rod and the top end of the second adjusting rod are hinged to each other.

[0011] Furthermore, a connecting stud is provided at the middle position on one side of the first adjusting rod and the second adjusting rod, a stabilizing plate is provided between the outer sides of the connecting stud, and eye nuts are provided on the outer sides of the connecting studs at both ends of one side of the stabilizing plate.

[0012] Furthermore, a wiring port is provided on one side of the rear end of the optical time domain reflectometer, and a dustproof rubber sleeve is fitted on the outside of the wiring port.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is a fiber optic fault location device, including an optical time domain reflectometer 1, a counterweight base 4 disposed below the optical time domain reflectometer 1, and a placement seat 14 disposed at the bottom of the optical time domain reflectometer 1 and the top of the counterweight base 4, and further including:

[0027] The shockproof sleeve 2 is fitted on both sides of the optical time domain reflectometer 1. A wiring port 13 is provided on one side of the rear end of the optical time domain reflectometer 1. After connecting the optical fiber to be tested to the wiring port 13, the optical time domain reflectometer 1 is turned on. The built-in laser emits a pulse-modulated optical signal. The emitted light and received light are separated by an optical direction coupler and then measured through the test optical fiber. The discontinuities in the optical fiber will reflect and scatter part of the optical signal. These reflected and scattered lights are received by the photodetector and converted into electrical signals. Finally, they are displayed as continuous signal waveforms on the screen. By analyzing these waveforms, information such as fiber loss, distance, and connector loss can be determined, and the breakpoints and endpoints can be accurately located. A dustproof rubber sleeve 12 is fitted on the outside of the wiring port 13. The dustproof rubber sleeve 12 can seal and protect the wiring port 13 when the device is not in use.

[0028] As a further implementation of this embodiment, such as Figure 1-4The hinge seat 18 shown is located at the midpoint between the top of the counterweight base 4 and the bottom of the placement seat 14. A first adjusting rod 3 is provided inside the hinge seat 18 at the bottom of the placement seat 14, and a second adjusting rod 6 is provided inside the hinge seat 18 at the top of the counterweight base 4. A through nut 5 is embedded in one side of the hinge seat 18, and a tightening bolt 19 is inserted between the other side of the hinge seat 18 and the top end of the first adjusting rod 3 and the bottom end of the second adjusting rod 6. One side of the tightening bolt 19 passes through the interior of the through nut 5. The tilt angle of the placement seat 14 can be adjusted by tilting the hinge seat 18 and the top of the first adjusting rod 3 as the hinge point. The tilt angle of the optical time domain reflectometer 1 mounted on it is adjusted. The bottom end of the first adjusting rod 3 and the top end of the second adjusting rod 6 are hinged to each other. Folding or extending the first adjusting rod 3 and the second adjusting rod 6 can adjust the operating height of the optical time domain reflectometer 1. A connecting stud 17 is provided at the middle position on one side of the first adjusting rod 3 and the second adjusting rod 6. A stabilizing plate 9 is provided between the outer sides of the connecting stud 17. A lifting eye nut 7 is provided on the outside of the connecting stud 17 at both ends on one side of the stabilizing plate 9. After adjusting the operating height and pitch angle of the optical time domain reflectometer 1 to a suitable position, tighten the loosening bolt 19 and the lifting eye nut 7.

[0029] In use, loosen the bolts 19 that pass through the top of the first adjusting rod 3 and the bottom of the second adjusting rod 6 on the other side of the hinge seat 18, and loosen the eye nut 7 on the outside of the connecting stud 17 so that the first adjusting rod 3 and the second adjusting rod 6 can be extended or folded. This allows the first adjusting rod 3 and the second adjusting rod 6, which are hinged to the hinge seat 18 and to each other, to be extended or folded. This adjusts the distance between the placement seat 14 and the counterweight base 4, thereby adjusting the placement height of the optical time domain reflectometer 1. Then, adjust the two sides of the stabilizing plate 9. Tightening the eye nut 7 on the outside of the end connecting stud 17 limits the first adjusting rod 3 and the second adjusting rod 6 to stabilize the height of the placement seat 14 after adjustment. Then, using the hinge point at the top of the hinge seat 18 and the first adjusting rod 3 as the hinge point, the tilt angle of the placement seat 14 can be adjusted to adjust the tilt angle of the optical time domain reflectometer 1 placed on the top of the placement seat 14. Then, tightening the loosening bolt 19 that passes through the through nut 5 can fix the hinge point between the first adjusting rod 3 and the second adjusting rod 6 and the hinge seat 18 so that it cannot rotate and ensures the stability of the device.

[0030] As a further implementation of this embodiment, such as Figure 1-4As shown, a stabilizing assembly is located at the bottom of the placement base 14 and on the outside of the optical time domain reflectometer 1. The stabilizing assembly includes a limiting plate 8, a cylinder 10, a telescopic rod 11, a compression spring 15, and a connecting piece 16. The cylinder 10 is located on both sides of the bottom of the placement base 14 and at the middle of the front end. The telescopic rod 11 is inserted through one side of the inside of the cylinder 10, and the compression spring 15 is installed on the other side of the inside of the cylinder 10. The connecting piece 16 is installed at the inner end of the telescopic rod 11. One side of the compression spring 15 and one side of the connecting piece 16 are fixedly connected. The connecting piece 16 connects the compression spring 15 and the telescopic rod 11 and limits one end of the telescopic rod 11 inside the cylinder 10. The limiting plate 8 is installed at the outer end of the telescopic rod 11. The limiting plate 8 is snapped onto the front end of the optical time domain reflectometer 1 and the outside of the anti-drop sleeve 2. By pulling the limiting plate 8 with the reset force of the compression spring 15, the optical time domain reflectometer 1 can be clamped and fixed on the top of the placement base 14 to facilitate the stable operation of the device by technicians for fiber optic fault detection.

[0031] When in use, pull back the limiting plate 8 set at the outer end of the telescopic rod 11, and stretch and compress the spring 15 through the telescopic rod 11 and the connecting piece 16 to open the limiting plate 8 at a suitable distance. Then place the optical time domain reflectometer 1 on the top of the placement base 14, so that the limiting plate 8 is locked on the outside of the anti-fall protective cover 2 and the front end of the optical time domain reflectometer 1. Then release the limiting plate 8 and pull the telescopic rod 11 in opposite directions through the reset pull of the compression spring 15, and drive the limiting plate 8 to move in opposite directions to clamp the two sides and the front end of the optical time domain reflectometer 1, thereby stabilizing the optical time domain reflectometer 1 on the top of the placement base 14.

[0032] Working principle: When using the fiber optic fault location device, first pull open the limiting plate 8 to place the optical time domain reflectometer 1 on top of the placement base 14, and then attach the limiting plate 8 to the outside of the anti-drop sleeve 2 and the front end of the optical time domain reflectometer 1. Then, release the limiting plate 8, and the return force of the compression spring 15 will pull the telescopic rod 11 in opposite directions, causing the limiting plate 8 to clamp and stabilize the optical time domain reflectometer 1 on top of the placement base 14. The device is then stably placed in a suitable operating position by the counterweight base 4. Then, loosen the tightening bolt 19 and the lifting nut 7 to the extent that the first adjusting rod 3 and the second adjusting rod 6 can be extended and folded. Extend or fold the first adjusting rod 3 and the second adjusting rod 6 according to operating habits and actual requirements to adjust the placement height of the optical time domain reflectometer 1. Then, tighten the lifting nut 7 to limit the first adjusting rod 3 and the second adjusting rod 6 by the stabilizing plate 9. Finally, adjust the pitch of the device with the hinge point between the hinge base 18 and the top of the first adjusting rod 3 as the hinge point. By tilting the base 14, the tilt angle of the optical time domain reflectometer 1 placed on top of the base 14 can be adjusted. Then, tightening the loosening bolt 19 inside the through-nut 5 will fix the first adjusting rod 3 and the second adjusting rod 6 at the hinge point with the hinge base 18, preventing them from rotating and ensuring the stability of the device. After adjusting the device, connect the optical fiber to the wiring socket 13 and turn on the optical time domain reflectometer 1. The built-in laser emits a pulse-modulated optical signal, which is separated from the received light by the optical direction coupler. Then, it is measured through the test optical fiber. The discontinuities in the optical fiber will reflect and scatter part of the optical signal. These reflected and scattered lights are received by the photodetector and converted into electrical signals, which are finally displayed as continuous signal waveforms on the screen. By analyzing these waveforms, information such as optical fiber loss, distance, and connector loss can be determined, and the breakpoints and endpoints can be accurately located. After the test is completed, the dustproof sleeve 12 is put on the wiring socket 13 for dust protection.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
