Technical Field

[0001] This utility model relates to the field of fiber optic terminal box technology, specifically a rack-mounted fiber optic terminal box. Background Technology

[0002] To facilitate the laying of optical fibers, fiber optic terminal boxes are required during the fiber optic laying process. A fiber optic terminal box is a termination point for an optical cable. One end of it is the optical cable, and the other end is a pigtail. Essentially, it is a device that splits an optical cable into individual optical fibers. The user optical cable terminal box installed on the wall provides functions such as fusion splicing of optical fibers to optical fibers, fusion splicing of optical fibers to pigtails, and connection of optical connectors.

[0003] Existing fiber optic terminal boxes typically have fixed internal structures for securing and organizing optical fibers. This makes it inconvenient to adjust the fiber's position during use, hindering fiber winding and organization, significantly increasing the difficulty and efficiency of fiber handling. To address this, we propose a rack-mounted fiber optic terminal box. Utility Model Content

[0004] The existing optical fiber terminal boxes mostly use fixed installations for fixing and organizing optical fibers, which makes it inconvenient to adjust their positions according to usage, and also makes it difficult to organize and wind up the optical fibers, greatly increasing the difficulty of fiber organization. This utility model provides a rack-mounted optical fiber terminal box that can effectively realize the sliding adjustment of two support bases and two side plates within the terminal box, and can also fix the adjusted support bases and side plates in position, bringing great convenience to the storage work and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A rack-mounted fiber optic terminal box includes a terminal box body and a sealed top cover connected to its top. Two support seats are slidably connected inside the terminal box body. Limiting plates are fixedly connected to the top and bottom of the support seats, and the top area of ​​the limiting plates is larger than the top area of ​​the support seats. Two side plates are also symmetrically arranged inside the terminal box body. The side plates are perpendicular to the support seats and are slidably connected to the terminal box body. A connecting plate is staggered between the two side plates, and the end of the connecting plate is slidably connected to the side plate. A positioning screw is vertically connected to the bottom surface of the terminal box body. The positioning screw passes through the intersection of the two connecting plates, and a locking nut is threaded onto the positioning screw.

[0006] Optionally, the side plate has an L-shaped cross-section and symmetrical strip grooves are provided at the top of the bent end of the side plate.

[0009] Optionally, a fixed base is fixedly attached to the bottom surface of the terminal box, the top of the fixed base is symmetrically connected to the first slide rail, and a slide groove is opened at the bottom of the side plate to slide the slide groove to the first slide rail.

[0010] Optionally, a second slide rail perpendicular to the position of the support base is symmetrically connected inside the terminal box, and a second slider is fixedly connected to the bottom of the support base, with the second slider slidably connected to the second slide rail.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a rack-mounted fiber optic terminal box, including a terminal box body 8 and a sealed top cover 1 connected to its top. To improve the stability of the connection between the sealed top cover 1 and the terminal box body 8, connecting skirts 20 are connected to the ends of both the sealed top cover 1 and the terminal box body 8, and the connecting skirts 20 are locked together by bolts. Figure 2 As shown, two support seats 3 are slidably connected inside the terminal box 8. Limiting plates 2 are fixedly connected to the top and bottom of the support seats 3, and the top area of ​​the limiting plates 2 is larger than the top area of ​​the support seats 3. The sides of the support seats 3 that are far apart from each other are set as arc-shaped sides to avoid damage caused by wrapping the optical fiber with right angles.

[0023] like Figure 2 , 4 As shown, in order to facilitate the stable sliding of the support base 3 within the terminal housing 8, a second slide rail 16 perpendicular to the position of the support base 3 is symmetrically connected within the terminal housing 8. A second slider 10 is fixedly connected to the bottom of the support base 3, and the second slider 10 is slidably connected to the second slide rail 16. When fixing the support base 3 after adjustment, the support base 3 is locked to the second slide rail 16 by locking bolts 9. Multiple threaded holes 17 are opened on the top of the second slide rail 16, and the locking bolts 9 are threadedly connected to the threaded holes 17. This greatly facilitates the user in adjusting the placement position of the support base 3, and also makes it easy to fix the position of the support base 3, effectively improving the practicality of the device.

[0024] like Figure 2 , 3As shown, two side plates 4 are symmetrically arranged inside the terminal box 8. In use, the side plate 4 has an L-shaped cross-section, and an outwardly extending top plate 5 is fixedly connected to the top of the side plate 4. The extended top plate 5 can limit the winding of the optical fiber, improving the stability of the optical fiber winding. The side plate 4 is perpendicular to the support base 3, and the two side plates 4 are slidably connected to the terminal box 8. In order to facilitate the installation and use of the device, a fixed base 6 is fixedly fastened to the bottom surface inside the terminal box 8. The top of the fixed base 6 is symmetrically connected to the first slide rail 7. A slide groove 19 is opened at the bottom of the side plate 4, and the slide groove 19 is slidably connected to the first slide rail 7.

[0025] In summary, in order to achieve synchronous sliding adjustment of the two side plates 4, the rack-mounted fiber optic terminal box has staggered connecting plates 15 between the two side plates 4 during use. The ends of the connecting plates 15 are slidably connected to the side plates 4. A strip groove 13 is symmetrically opened at the top of the bent end of the side plate 4. A positioning rod 14 is fixedly fastened to the bottom surface of the end of the connecting plate 15. The positioning rod 14 is slidably connected in the strip groove 13. A positioning screw 11 is vertically connected to the bottom surface inside the terminal box body 8. The positioning screw 11 passes through the intersection of the two connecting plates 15. An annular seat 18 is fixedly connected to the center of the connecting plate 15. The annular seat 18 is coaxially connected to the positioning screw 11, which plays a positioning role in the placement of the connecting plate 15.

[0026] Simultaneously, by pushing the two side plates 4, the two connecting plates 15 can open and rotate along the positioning screw 11. During rotation, the positioning rod 14 is pushed to slide synchronously in the strip groove 13. After adjustment, a locking nut 12 is threaded onto the positioning screw 11. Tightening the locking nut 12 fixes the position of the annular seat 18, thereby fixing the position of the two side plates 4. This utility model can effectively realize the sliding adjustment of the two support seats 3 and the two side plates 4 in the terminal box 8, and can also fix the position of the adjusted support seats 3 and side plates 4. It is not only simple in structure, but also brings great convenience to the storage work.
