Description
Technical Field
[0001] This utility model belongs to the field of optical fiber line testing technology, and specifically relates to a monitoring instrument for automatically monitoring the status of optical fiber lines. Background Technology
[0002] Automatic fiber optic line monitoring instruments are core equipment for ensuring the stable operation of fiber optic networks. Utilizing technologies such as optical time-domain reflectometry, they can perform real-time, remote monitoring of fiber optic lines, accurately locating fault points such as line interruptions, abnormal losses, and loose connectors with extremely small error margins. These monitors feature automatic inspection capabilities, periodically collecting fiber optic performance parameters and analyzing data trends through intelligent algorithms to provide early warnings of potential problems. They also support multi-channel parallel monitoring, managing multiple fiber optic lines simultaneously, and providing a visual interface to intuitively present line topology and fault information. Furthermore, they include data storage and historical record query functions, facilitating retrospective analysis by maintenance personnel. Widely used in communications, power, and security fields, they significantly improve the efficiency and reliability of fiber optic network maintenance.
[0003] In practical applications, fiber optic cables are subject to external forces such as pulling, vibration, or shaking. For example, in communication equipment rooms, the movement of equipment, personnel operation, or vibration of the air conditioning system can all affect the fiber optic cable. The connection between the fiber optic adapter and the monitoring instrument's optical interface, as well as the port of the fiber optic cable to be monitored, is prone to loosening, leading to interruption or instability in optical signal transmission. This affects the accuracy and continuity of monitoring data. Moreover, if the fiber optic adapter is accidentally detached during fiber optic monitoring, the monitoring instrument will be unable to obtain the status information of the fiber optic line, miss faults or abnormalities that occur in the fiber optic line, and fail to issue alarms in a timely manner, thus affecting the reliability and security of the entire fiber optic network. Utility Model Content
[0004] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a monitoring instrument for automatically monitoring the status of optical fiber lines, so as to solve the problem that in actual application scenarios, optical fibers are subject to external forces such as pulling, vibration or shaking, and the connection between the optical fiber adapter and the optical interface of the monitoring instrument and the port of the optical fiber to be monitored is easy to loosen, resulting in interruption or instability of optical signal transmission, which affects the accuracy and continuity of monitoring data.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An automatic monitoring instrument for monitoring the status of optical fiber lines includes an instrument body and an optical fiber body. Heat sinks are symmetrically fixedly connected to both sides of the instrument body. Interfaces are symmetrically opened on one side of the instrument body. An optical fiber adapter is installed at one end of the optical fiber body. The optical fiber adapter is plugged into the interface. A mounting base is symmetrically and movably connected to one side of the instrument body. Mounting components are symmetrically installed on one side of the mounting base. Anti-disconnection components are installed inside the mounting base.
[0007] The anti-dropout assembly includes a through slot, a clamping block, a threaded rod, a threaded hole, and a knob. A through slot is provided on one side of the mounting base, with the clamping block symmetrically slidably connected inside. Threaded holes are provided at both the top and bottom of the mounting base, communicating with the inside of the through slot. A threaded rod is threadedly connected inside the threaded hole, with one end extending into the through slot and rotatably connected to the clamping block. A knob is fixedly connected to the other end of the threaded rod. This securely fixes the optical fiber to the interface of the detector body, effectively preventing the connection between the optical fiber adapter and the interface from loosening due to external pulling, vibration, or shaking. It also avoids damage to the adapter interface and optical fiber end face caused by repeated plugging and unplugging, reducing the frequency of maintenance operations such as adapter replacement or re-splicing of optical fibers, thereby lowering maintenance material and labor costs.
[0008] As a preferred technical solution, the clamping end of the clamping block is glued with an anti-slip pad. The surface of the anti-slip pad is provided with anti-slip protrusions. The anti-slip pad is made of soft rubber. When clamping the optical fiber, it can evenly distribute the pressure and avoid the clamping block directly contacting the optical fiber, thus preventing damage to the surface of the optical fiber.
[0009] As a preferred technical solution, guide grooves are provided on both sides of the through slot, and guide blocks are fixedly connected to both sides of the clamping block. The guide blocks and guide grooves are slidably connected. During the process of the threaded rod driving the clamping block to clamp or release the optical fiber, the clamping block can remain stable and will not shake or shift, thereby ensuring that the clamping force on the optical fiber is evenly distributed and avoiding damage to the optical fiber or unstable connection due to uneven clamping.
[0010] As a preferred technical solution, the mounting assembly includes a cavity, a return spring, a movable plate, and a locking block. Assembly blocks are symmetrically fixedly connected to one side of the mounting base. A cavity is formed inside each assembly block. A return spring is fixedly connected to one side of the cavity, and a movable plate is fixedly connected to the other end of the return spring. The movable plate is slidably connected to the cavity. A locking block is fixedly connected to the other side of the movable plate, with its other end extending outwards from the assembly block. A bevel is provided on one side of the locking block. Assembly slots are symmetrically formed on one side of the detector body. The assembly blocks are inserted into the assembly slots, and a locking groove is formed on one side of each assembly slot for locking. The block and locking groove are snap-fitted together. An unlocking block is slidably connected inside the locking groove. Limiting blocks are fixedly connected to both sides of the unlocking block. Limiting grooves are opened on both sides inside the locking groove. The limiting blocks and limiting grooves are slidably connected. A push groove is opened on one side of the detector body. The push groove is connected to the locking groove, which enhances the flexibility and adaptability of the equipment. The equipment can better serve diverse work scenarios. Moreover, without the need for complicated tools or steps, the connection can be quickly completed by simply inserting the block and applying pressure to the inclined surface of the locking block. This reduces the technical requirements for operators.
[0011] As a preferred technical solution, an audible and visual alarm is installed on the top of the detector body. The audible and visual alarm is electrically connected to the detector body, which can attract the attention of the staff more quickly and effectively, so that they can know that there is a problem with the fiber optic line at the first time and take corresponding measures to deal with it in a timely manner.
[0012] In summary, the present invention has the following main advantages:
[0013] First, in this utility model, the fiber optic adapter at one end of the fiber optic body is inserted into the interface on the detector body. By rotating the knob, the threaded rod is controlled to rotate inside the threaded hole, thereby causing the threaded rod to move the clamping block. When the clamping block moves, it causes the guide block to slide inside the guide groove. The clamping block clamps and fixes the fiber optic body, which can firmly fix the fiber optic body at the interface of the detector body. This effectively prevents the connection between the fiber optic adapter and the interface from becoming loose due to external pulling, vibration, or shaking. It also avoids damage to the adapter interface and fiber end face caused by repeated plugging and unplugging, reducing the frequency of maintenance operations such as replacing the adapter or re-splicing the fiber, thereby reducing the material and labor costs of maintenance.
[0014] Secondly, in this utility model, the mounting base is combined with one side of the detector body, allowing the assembly block to be inserted into the assembly groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to press against the return spring. The locking block retracts into the cavity. When the locking block moves to the locking groove, it pops out and engages with the locking groove for fixation. This can flexibly meet the needs of equipment installation, disassembly, and reassembly, enhancing the flexibility and adaptability of the equipment. This allows the equipment to better serve diverse work scenarios. Moreover, without the need for complex tools or steps, the connection can be quickly completed by simply inserting the device and applying squeezing force to the inclined surface of the locking block, reducing the technical requirements for operators.

An anti-drop-off component 10 is installed inside the mounting base 7.
[0022] The anti-derailment assembly 10 includes a through groove 101, a clamping block 102, a threaded rod 103, a threaded hole 104, and a knob 105. A through groove 101 is provided on one side of the mounting base 7. The clamping block 102 is symmetrically slidably connected inside the through groove 101. Threaded holes 104 are provided at both the top and bottom of the mounting base 7, communicating with the inside of the through groove 101. A threaded rod 103 is threadedly connected inside the threaded hole 104, with one end of the threaded rod 103 extending into the through groove 101 and connecting with the clamping block 105. 02 Rotary connection, the other end of the threaded rod 103 is fixedly connected to the knob 105. Insert the fiber optic adapter 3 at one end of the fiber optic body 2 into the interface 4 on the detector body 1. Rotate the knob 105 to control the threaded rod 103 to rotate inside the threaded hole 104, thereby causing the threaded rod 103 to drive the clamping block 102 to move. When the clamping block 102 moves, it drives the guide block 13 to slide inside the guide groove 12. The clamping block 102 clamps and fixes the fiber optic body 2.
[0023] refer to Figure 4 The clamping end of the clamping block 102 is glued with an anti-slip pad 11. The surface of the anti-slip pad 11 is provided with anti-slip protrusions. The anti-slip pad 11 is made of soft rubber. With the anti-slip pad 11, the pressure can be evenly distributed when clamping the optical fiber, so as to avoid the clamping block 102 directly contacting the optical fiber and causing damage to the surface of the optical fiber.
[0024] refer to Figure 4 Guide grooves 12 are provided on both sides of the through groove 101. Guide blocks 13 are fixedly connected to both sides of the clamping block 102. The guide blocks 13 and the guide grooves 12 are slidably connected. When the threaded rod 103 drives the clamping block 102 to move, the clamping block 102 drives the guide blocks 13 to slide inside the guide grooves 12.
[0025] refer to Figure 3The mounting assembly 14 includes a cavity 141, a return spring 142, a movable plate 143, and a locking block 144. A mounting block 8 is symmetrically fixedly connected to one side of the mounting base 7. A cavity 141 is formed inside the mounting block 8. A return spring 142 is fixedly connected to one side of the cavity 141. A movable plate 143 is fixedly connected to the other end of the return spring 142. The movable plate 143 is slidably connected to the cavity 141. A locking block 144 is fixedly connected to the other side of the movable plate 143. The other end of the locking block 144 extends outward from the outside of the mounting block 8. A slope is provided on one side of the locking block 144. The detector body 1... The assembly slots 9 are symmetrically arranged on both sides. The assembly block 8 is inserted into the assembly slot 9. A locking groove 15 is provided on one side inside the assembly slot 9. The locking block 144 is snapped into the locking groove 15. The mounting base 7 is combined with one side of the detector body 1, so that the assembly block 8 is inserted into the assembly slot 9. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, so that the locking block 144 drives the moving plate 143 to press against the return spring 142. The locking block 144 retracts into the cavity 141. When the locking block 144 moves to the locking groove 15, the locking block 144 pops out and snaps into the locking groove 15 for fixation.
[0026] refer to Figure 3 An unlocking block 17 is slidably connected inside the locking groove 15. Limiting blocks 18 are fixedly connected to both sides of the unlocking block 17. Limiting grooves 19 are opened on both sides inside the locking groove 15. The limiting blocks 18 and the limiting grooves 19 are slidably connected. A push groove 16 is opened on one side of the detector body 1. The push groove 16 is connected to the locking groove 15. Pushing the unlocking block 17 causes the unlocking block 17 to slide inside the locking groove 15. At the same time, the unlocking block 17 drives the limiting blocks 18 to slide inside the limiting grooves 19. The unlocking block 17 pushes the locking block 144, causing the locking block 144 to drive the moving plate 143 to press against the return spring 142. The return spring 142 is compressed. At the same time, the locking block 144 retracts into the cavity 141. The locking block 144 and the locking groove 15 are no longer engaged.
[0027] refer to Figure 1 The detector body 1 is equipped with an audible and visual alarm 6 on its top. The audible and visual alarm 6 is electrically connected to the detector body 1. The audible and visual alarm 6 can attract the attention of the staff more quickly and effectively, so that they can know that there is a problem with the fiber optic line at the first time and take corresponding measures to deal with it in a timely manner.
[0028] Operating principle and advantages: First, the mounting base 7 is joined to one side of the detector body 1, so that the assembly block 8 is inserted into the assembly groove 9. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, so that the locking block 144 drives the moving plate 143 to press against the return spring 142. The locking block 144 retracts into the cavity 141. When the locking block 144 moves to the locking groove 15, the locking block 144 pops out and engages with the locking groove 15 to fix it, thus completing the installation of the mounting base 7. Then, the fiber optic adapter 3 at one end of the fiber optic body 2 is inserted into the interface 4 on the detector body 1. The knob 105 is turned to control the threaded rod 103 to rotate inside the threaded hole 104, so that the threaded rod 103 drives the clamping block 102 to move. When the clamping block 102 moves, it drives the guide block 13 to slide inside the guide groove 12. The clamping block 102 clamps and fixes the fiber optic body 2.
[0029] This invention can firmly fix the optical fiber body 2 to the interface 4 of the detector body 1, effectively preventing the connection between the optical fiber adapter 3 and the interface 4 from becoming loose due to external pulling, vibration or shaking, and avoiding damage to the adapter interface 4 and the optical fiber end face caused by repeated plugging and unplugging. It also reduces the frequency of maintenance operations such as replacing the adapter or re-splicing the optical fiber, thereby reducing the material and labor costs of maintenance.
