Description

Technical Field

[0001] This utility model relates to the field of optical fiber monitoring technology, specifically a hub structure and an optical fiber monitoring device. Background Technology

[0002] Fiber optic monitoring devices are a general term for systems that utilize fiber optic sensing technology to achieve real-time monitoring and data transmission of environmental parameters. Their core principle lies in sensing dynamic changes in external physical quantities, such as temperature, strain, and vibration, by precisely capturing subtle changes in light signals. These devices possess excellent resistance to electromagnetic interference, can achieve long-distance coverage monitoring, and exhibit extremely high sensitivity and outstanding real-time performance, playing a crucial role in numerous fields.

[0003] For example, patent CN215898222U discloses an online monitoring device for fiber optic monitoring. The outer shell of the online monitor is equipped with a heat dissipation and drying component. Sealing rubber membranes are adhered to the inner walls on both sides of the ventilation holes. Installation ports are located at the top and bottom of the online monitor shell. A limit slider is welded to one end of the drying box. A protective wire clamping component is installed on the side of the online monitor shell near the module box. Wire holes are evenly distributed on the side of the protective plate, and sliding plates are slidably installed at both ends of the wire holes. Adjacent right-angle compression sliders are connected by springs. After opening the online monitor shell and replacing the module, this online monitoring device uses a vacuum pump to extract air from the shell, reducing the internal air pressure until the sealing rubber membrane deforms due to insufficient pressure. This reduces the internal oxygen content and humidity. The device is then dried in the drying box, ensuring a low-pressure, low-oxygen, and dry environment inside, preventing short circuits and fires, thus improving safety.

[0004] The aforementioned monitoring device still has certain shortcomings:

[0005] Although the aforementioned detection device possesses the ability to prevent short-circuit fires and significantly improves safety, its design has shortcomings in cable management. Specifically, the connection cables of different modules (such as the OTDR module, OSW module, and power module) lack a centralized organization mechanism, leading to frequent tangling and knotting of multiple cables. This increases the difficulty and complexity of subsequent maintenance of the device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cable hub structure and fiber optic monitoring device that prevents cables from becoming tangled or knotted.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cable management structure, including a protective plate, with side plates fixedly connected to both ends of the protective plate, and multiple cable clamping grooves provided on the side of the side plate away from the protective plate, the cable clamping grooves being equidistantly distributed, a bottom plate fixedly connected to the lower end of the protective plate near the side plate, and an L-shaped dustproof plate slidably connected to the side plate away from the protective plate.

[0008] Furthermore, a limiting slider is fixed to the side of the side plate away from the protective plate, and limiting grooves matching the limiting slider are opened at both ends of the dustproof plate.

[0009] Furthermore, a slot is provided at the upper end of the side plate, and storage slots are provided at both ends of the top of the dustproof plate. Inserts are slidably connected inside the storage slots, and the inserts match the slots.

[0010] Furthermore, an elastic element is fixedly connected to one end of the insert block away from the slot, the other end of the elastic element is fixedly connected to the end of the receiving groove, and a lever is fixedly connected to the top of the insert block away from the slot.

[0011] Furthermore, a baffle is fixed to the side of the lever away from the slot, and a translation groove communicating with the storage slot is opened at the upper end of the dustproof plate, and the translation groove matches the baffle.

[0012] Furthermore, the end of the wire-locking groove is U-shaped, and elastic blocks are fixed to the upper and lower ends of the wire-locking groove on the side away from the protective plate.

[0013] A fiber optic monitoring device includes an online monitor body, which further includes the aforementioned hub structure. Mounting sliders are fixedly connected to the upper and lower ends of the back of the online monitor body. Mounting grooves matching the mounting sliders are formed on the upper and lower ends of the protective plate near the online monitor body. A positioning frame is fixedly connected to one side of the protective plate. A positioning slider is fixedly connected to the end of the online monitor body near the positioning frame. A positioning plate matching the positioning frame is slidably connected to the positioning slider. A positioning bolt is threaded onto the positioning plate, and the end of the positioning bolt penetrates the positioning plate and abuts against the positioning slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] During installation, this type of cable management structure and fiber optic monitoring device involves first installing a protective plate onto the main body of the online monitor, then connecting the cable to the main body of the online monitor through the cutout on the protective plate, then securing the cable in the cable slot, and finally connecting the dustproof plate to the side plate to restrict the cable and prevent it from detaching from the side plate. This not only protects the cable but also allows it to be neatly organized, preventing tangling and knotting. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-6 A hub structure and fiber optic monitoring device includes a protective plate 3, with side plates 9 fixedly connected to both ends of the protective plate 3. Multiple wire-clamping grooves 13 are provided on the side of the side plate 9 away from the protective plate 3. The wire-clamping grooves 13 are evenly distributed. A bottom plate 22 is fixedly connected to the lower end of the protective plate 3 near the side plate 9. An L-shaped dustproof plate 10 is slidably connected to the side plate 9 away from the protective plate 3.

[0025] In this utility model, the cable management structure and fiber optic monitoring device are installed by first installing the protective plate 3 onto the main body 1 of the online monitor, then connecting the cable to the main body 1 of the online monitor through the cutout on the protective plate 3, then securing the cable in the cable slot 13 on the side plate 9, and finally connecting the dustproof plate 10 to the side plate 9 to restrict the cable and prevent it from detaching from the side plate 9. This not only protects the cable but also allows it to be neatly organized, preventing tangling and knotting.

[0026] like Figures 2 to 5 As shown, a limiting slider 11 is fixedly connected to the side of the side plate 9 away from the protective plate 3, and limiting grooves 12 matching the limiting slider 11 are opened at both ends of the dustproof plate 10.

[0027] Specifically, the dustproof plate 10 is connected to the side plate 9 through the limiting slider 11 and the limiting groove 12, making it easier to connect the dustproof plate 10 and the side plate 9.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, a slot 15 is provided at the upper end of the side plate 9, and storage slots 16 are provided at both ends of the top of the dustproof plate 10. An insert 18 is slidably connected inside the storage slot 16, and the insert 18 matches the slot 15.

[0029] Specifically, after the dustproof plate 10 is connected to the side plate 9, the insert block 18 can be moved to insert the insert block 18 into the slot 15, thereby restricting the dustproof plate 10 and preventing the dustproof plate 10 from detaching from the side plate 9.

[0030] like Figure 5 and Figure 6 As shown, an elastic element 21 is fixedly connected to one end of the insert 18 away from the slot 15, and the other end of the elastic element 21 is fixedly connected to the end of the storage groove 16. A toggle block 19 is fixedly connected to the top of the insert 18 away from the slot 15.

[0031] Specifically, the elastic element 21 restricts the insertion block 18 to prevent the insertion block 18 from detaching from the slot 15 on its own, thus preventing the insertion block 18 from losing its restrictive effect. At the same time, the toggle block 19 makes it easier and less effort to move the insertion block 18.

[0032] like Figure 5 and Figure 6 As shown, a baffle 20 is fixed to the side of the lever 19 away from the slot 15, and a translation groove 17 connected to the storage groove 16 is opened at the upper end of the dustproof plate 10. The translation groove 17 matches the baffle 20.

[0033] Specifically, after the insert 18 is inserted into the slot 15, the baffle 20 will be positioned at the upper end of the storage slot 16, thereby blocking the notch in the storage slot 16 and preventing impurities from entering the storage slot 16, which could cause corrosion and damage to the elastic element 21 and other structures.

[0034] like Figure 4 As shown, the end of the cable clamping groove 13 is U-shaped, and elastic blocks 14 are fixed to the upper and lower ends of the cable clamping groove 13 on the side away from the protective plate 3. The U-shaped cable clamping groove 13 is less likely to scratch the cable, and at the same time, the elastic blocks 14 will restrict the cable and prevent the cable from falling out of the cable clamping groove 13 on its own.

[0035] A fiber optic monitoring device includes an online monitor body 1, which also includes the aforementioned hub structure. Mounting sliders 2 are fixedly connected to the upper and lower ends of the back of the online monitor body 1. Mounting grooves 8 matching the mounting sliders 2 are provided at the upper and lower ends of the protective plate 3 near the online monitor body 1. A positioning frame 7 is fixedly connected to one side of the protective plate 3. A positioning slider 4 is fixedly connected to the end of the online monitor body 1 near the positioning frame 7. A positioning plate 5 matching the positioning frame 7 is slidably connected to the positioning slider 4. A positioning bolt 6 is threaded onto the positioning plate 5, and the end of the positioning bolt 6 penetrates the positioning plate 5 and abuts against the positioning slider 4.

[0036] Specifically, when installing the protective plate 3, simply align the mounting groove 8 on the protective plate 3 with the mounting slider 2, then move the protective plate 3 so that the mounting slider 2 is fully inserted into the mounting groove 8, then push the positioning plate 5 so that the end of the positioning plate 5 is inserted into the positioning frame 7, and finally tighten the positioning bolt 6 so that the end of the positioning bolt 6 abuts against the positioning slider 4. The whole installation process is simple, convenient and easy to operate.

[0037] It is worth noting that: the elastic element 21 is preferably made of stainless steel or piano wire, which has a high fatigue limit and is suitable for long-term reciprocating motion. Its surface is treated with nickel plating or coating to have strong corrosion resistance. The elastic force range of the elastic element 21 is about 10N-20N, and the specific elastic force value should be changed according to the actual application requirements. This elastic force range is to avoid the occurrence of elastic failure.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
