Description

Technical Field

[0001] This utility model relates to the field of optical fiber transmission detection technology, and more specifically, to an auxiliary device for optical fiber transmission detection. Background Technology

[0002] Fiber optic testing is a technique used to evaluate the performance of single-mode and multimode fiber optic systems. It aims to ensure fiber optic connection quality, reduce potential faults, and quickly locate fault points. Its core objectives include verifying link reliability and quantifying signal transmission loss. When using a laser pointer to test the continuity of a fiber optic cable, a red light is emitted from one end of the cable, and the other end is observed for illumination. However, some fiber optic cables are located indoors, with one end placed in an electrical distribution box. When the laser pointer is connected to one end of the cable, it is inconvenient to fix it securely. When personnel observe illumination at the other end of the cable, the weight of the laser pointer can cause the cable to bend, affecting light transmission and thus the accuracy of fiber optic measurements. Furthermore, when external light is strong, the illumination at the other end of the cable may be difficult to observe. Therefore, an auxiliary device for fiber optic continuity testing is proposed.

[0021] As shown in Figures 1 to 5, an auxiliary device for optical fiber transmission detection includes a red light lamp 1. A support ring 3 is sleeved on the outer side of the red light lamp 1, and a magnet 8 is fixedly sleeved on the outer side of the support ring 3. When the distribution box is made of iron, the magnet 8 is used to attract and fix the support ring 3 and the red light lamp 1 in a suitable position. Two sets of first rotating seats 4 are fixedly connected to the outer side of the support ring 3. A rotating frame 5 is damped and rotatably connected to the inner side of each of the two sets of first rotating seats 4. A set of second rotating seats 6 is damped and rotatably connected to the ends of each of the two sets of second rotating seats 6. A support rod 7 is fixedly connected to the ends of each of the two sets of second rotating seats 6. A light detection mechanism 9 is provided at the end of the red light lamp 1. The support ring 3... The inner wall is provided with a rubber sleeve 2. The inner side of the rubber sleeve 2 fits against the outer side of the red light 1. The rubber sleeve 2 ensures the stability of the support ring 3 when it is fitted onto the outer handle of the red light 1. In addition, the fitting position of the support ring 3 is adjusted according to the length of the support rod 7. When the rotating frame 5 rotates and the support rod 7 unfolds outward, the end of the support rod 7 is flush with the tail end of the red light 1, so that the two support rods 7 and the red light 1 form a triangular structure to support the red light 1. Example 2

[0022] Based on Embodiment 1, as shown in Figures 1 to 5, the optical detection mechanism 9 includes a sleeve 10 fitted onto the end of the red light lamp 1. A viewing plate 12 is fixedly fitted onto the side of the sleeve 10. Slide grooves 13 are provided on both sides of the sleeve 10. An end cap 11 is fitted onto the end of the sleeve 10. The end of the end cap 11 extends into the inner cavity of the sleeve 10 and is fixedly connected to a small lens 16. Connecting brackets 14 are fixedly connected to both sides of the end cap 11. A cylinder 15 is fixedly connected to the inner side of the ends of the two connecting brackets 14. The end of the cylinder 15 extends into the inner cavity of the slide groove 13. When the optical fiber is tested for light transmission, the other end of the optical fiber is inserted into the inner cavity of the sleeve 10, so that the light shines onto the small lens 16. The light on the small lens 16 is observed through the viewing plate 12. Example 3

[0023] Based on Embodiments 1 and 2, as shown in Figures 1, 4, and 5, a fitting groove 17 is provided on the inner side of the other end of the sleeve 10. The inner diameter of the fitting groove 17 is equal to the outer diameter of the end of the red light lamp 1, ensuring that the end of the red light lamp 1 can be fitted into the inner cavity of the fitting groove 17, thereby fitting the sleeve 10 onto the end of the red light lamp 1. The outer diameter of the end of the end cap 11 is equal to the inner diameter of the sleeve 10, ensuring that the end of the end cap 11 can be inserted into the end of the sleeve 10. Furthermore, there is a certain amount of friction between the side of the end of the end cap 11 and the inner wall of the sleeve 10, ensuring the stability of the end cap 11 inserted into the end of the sleeve 10. The outer side of the cylinder 15 fits against the inner side of the sliding groove 13, ensuring the stability of the cylinder 15 sliding in the sliding groove 13.

[0024] It should be noted that this utility model is an auxiliary device for optical fiber transmission detection. In use, first, the rubber sleeve 2 and support ring 3 are fitted onto the appropriate position on the handle end of the red light lamp 1, and the sleeve 10 is removed from the end of the red light lamp 1, so that one end of the optical fiber is inserted into the end light source of the red light lamp 1. Then, the rotating frame 5 is rotated to extend the support rod 7 outwards, while simultaneously making the two support rods 7 parallel to the red light lamp 1. The triangular structure between the two support rods 7 and the red light lamp 1 supports the red light lamp 1, thus placing the red light lamp 1 on the bottom surface of the distribution box or other flat surface. Additionally, when the distribution box is made of iron, the magnetic attraction between the magnet 8 and the distribution box can be used to fix the red light lamp 1 in a suitable position to prevent bending of the optical fiber after connection. Then, the other end of the optical fiber is inserted into the inner cavity of the sleeve 10, so that the end of the optical fiber is aligned with the small lens 16 on the end cap 11. Simultaneously, the optical fiber is inserted into the sleeve 10 using the palm of the hand. One end of the inner cavity is sealed. At this time, the light from the end of the optical fiber shines onto the small lens 16. The light on the small lens 16 is observed through the viewing plate 12. When no light is displayed on the small lens 16, it indicates that the optical fiber is faulty. Finally, the end cap 11 can be pulled outward so that the end of the end cap 11 is removed from the inner cavity of the sleeve 10. At this time, it is possible to directly observe whether there is light at the end of the optical fiber in the inner cavity of the sleeve 10. The sleeve 10 blocks most of the visible light outside the end of the optical fiber, making it easier to observe the light at the end of the optical fiber.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
