Description

Technical Field

[0001] This utility model relates to the field of optical fiber distribution technology, and in particular to an optical fiber distribution frame. Background Technology

[0002] Fiber optic distribution frames are wiring connection devices between optical cables and optical communication equipment or between optical communication equipment. Fiber optic distribution frames are used for the termination and distribution of the main optical cables at the central office in optical fiber communication systems. They can facilitate the connection, distribution, and scheduling of optical fiber lines. Fiber optic distribution frames can be used to fix optical cables, protect optical cables, and perform other functions such as distribution.

[0003] The patch panels on common fiber optic patch panels are usually installed individually on a fixed bracket inside the housing by plugging and unplugging. When replacing a patch panel, it is necessary to release the clip between the bracket and the patch panel. When the patch panel is placed deep inside the housing, the patch panels at the deepest part are blocked by the outer parts when replacing them one by one, which can obstruct the view and easily lead to the risk of accidental contact. This needs to be optimized. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a fiber optic distribution frame, including a housing 1, a front door 2 of the housing, a movable bracket 5, and fiber optic distribution units 6. The movable bracket 5 is placed inside the housing 1, and each fiber optic distribution unit 6 is placed side by side inside the movable bracket 5.

[0028] The movable bracket 5 has a plug-in structure on its inner side, and the left and right ends of the fiber optic patch panel 6 are detachably connected to the plug-in structure.

[0029] The bottom of the inner side of the housing 1 is provided with a guide rail structure for easy removal of the movable bracket 5, and the guide rail structure is detachably connected to the movable bracket 5.

[0030] The movable support 5 is provided with fixed plates 13 on the left and right sides. At least two rubber blocks 12 are provided on the side of the fixed plate 13 away from the movable support 5. A rotary push device for adjusting the friction between the rubber blocks 12 and the housing 1 is provided between the fixed plate 13 and the rubber blocks 12.

[0031] The fiber optic patch panel 6 is integrated on the movable bracket 5 inside the housing 1. The movable bracket 5 is slidably mounted inside the housing 1 using a guide rail structure. The left and right sides of the movable bracket 5 are fixed to the housing 1 by internal bracing and screwing. When replacing the fiber optic patch panel 6, if the view is obstructed, the fixation between the movable bracket 5 and the housing 1 can be released, and the movable bracket 5 can be pulled out completely from the housing 1. All fiber optic patch panels 6 are exposed on the outside of the housing 1, allowing staff to maintain the fiber optic patch panels 6 in an open environment, avoiding misoperation or component damage due to limited space.

[0032] Regarding the plug-in / plug-out mechanism:

[0033] The insertion and removal structure includes multiple positioning plates 10 and plate inserts 16. The positioning plates 10 are fixedly connected to the inside of the movable bracket 5, and the plate inserts 16 are fixedly connected to the left and right sides of the fiber optic patch panel 6. The front of the positioning plate 10 has slots 11 that match the plate inserts 16. The plate inserts 16 have a T-shaped cross-section, and the slots 11 are slidably connected to the plate inserts 16. Multiple fiber optic patch panels 6 are placed inside the movable bracket 5. During assembly, the plate inserts 16 on both sides of the fiber optic patch panel 6 are aligned with the slots 11 on the positioning plates 10 and inserted. The slots 11, by cooperating with the plate inserts 16, limit the movement of the fiber optic patch panel 6 from both sides. To replace the fiber optic patch panel 6, simply pull it outwards.

[0034] Regarding the guide rail structure:

[0035] The guide rail structure includes a guide rail 7 and a slider 8. The guide rail 7 is laid on the bottom of the inner wall of the housing 1 and is fixedly connected to the housing 1. The slider 8 is fixedly connected to the lower end of the movable bracket 5. The lower end of the slider 8 has a groove 9 that matches the guide rail 7. The cross-section of the guide rail 7 is T-shaped, and the guide rail 7 is slidably connected to the groove 9. After the movable bracket 5 is unlocked by the rotary push device, the movable bracket 5 is pulled outward, and the slider 8 at the lower end of the movable bracket 5 will disengage from the front end of the guide rail 7, so that the movable bracket 5 can be removed completely, making disassembly and maintenance convenient.

[0036] Regarding the rotary propulsion device:

[0037] In one embodiment, the rotary pusher includes a threaded cylinder 19 and a threaded post 18. One end of the threaded cylinder 19 is fixedly connected to the fixed plate 13, and the other end of the threaded cylinder 19 is sleeved on the outside of the threaded post 18. The threaded post 18 is threadedly connected to the threaded cylinder 19, and the end of the threaded post 18 away from the threaded cylinder 19 is fixedly connected to the rubber block 12. Rotating the threaded post 18 will unscrew it from the threaded cylinder 19, causing the threaded post 18 to push the rubber block 12 closer to the inner wall of the housing 1. At the same time, rotating the threaded posts 18 on the left and right sides of the movable bracket 5 will cause the two rubber blocks 12 to support the movable bracket 5 from the left and right sides. The friction between the rubber blocks 12 and the housing 1 keeps the movable bracket 5 fixed.

[0038] In a preferred embodiment, a limiting groove 20 is formed on the inner side of the threaded cylinder 19, and a limiting ring 21 is provided in the limiting groove 20. The limiting ring 21 is fixedly connected to the threaded post 18, and the diameter of the limiting ring 21 is larger than the diameter of the threaded post 18. When the threaded post 18 is screwed in and out along the inner wall of the threaded cylinder 19, the limiting ring 21 fixed to the threaded post 18 will also slide along the limiting groove 20. The limiting groove 20 limits the threaded post 18 by cooperating with the limiting ring 21, ensuring that the threaded post 18 will not detach from the threaded cylinder 19 during adjustment.

[0039] To increase the structural strength of the movable support 5, a reinforcing plate 15 is provided on the back of the movable support 5, and the left and right ends of the reinforcing plate 15 are fixedly connected to the movable support 5.

[0040] The housing 1 is made of metal, providing overall structural support for the fiber optic patch panel and protecting internal components from external environmental influences. For easy mounting, mounting plates 3 are provided on both the left and right sides of the housing 1, with multiple pre-drilled holes 4 for easy fixation of the housing 1 to a cabinet or wall. Some housings 1 are equipped with grounding terminals, connected to the computer room grounding system via a grounding wire to release static electricity or induced voltage, protecting equipment and personnel safety.

[0041] To prevent the fiber optic patch panel 6 from becoming loose during use, mounting plates 17 are provided on both the left and right sides of the fiber optic patch panel 6. The mounting plates 17 are fixedly installed on the front of the fiber optic patch panel 6. The mounting plates 17 also have reserved holes 4. During installation, the fiber optic patch panel 6 is pushed between the two positioning plates 10. The mounting plates 17 on the fiber optic patch panel 6 will rest on the front of the positioning plates 10. The connecting bolts are then screwed into them, and the connecting bolts will simultaneously engage with the bolt holes on the positioning plates 10 to secure the fiber optic patch panel 6.

[0042] How this application works:

[0043] The fiber optic patch panel 6 is integrated on the movable bracket 5 inside the housing 1. The left and right sides of the movable bracket 5 are fixed to the housing 1 by internal support screwing. When replacing the fiber optic patch panel 6, if the field of vision is obstructed, the tightness between the rubber block 12 and the housing 1 can be adjusted by the screwing device. After releasing the fixation between the movable bracket 5 and the housing 1, the movable bracket 5 can be pulled out completely from the housing 1. At this time, all fiber optic patch panels 6 are exposed outside the housing 1. The staff can maintain the fiber optic patch panels 6 in an open environment, avoiding misoperation or component damage caused by space constraints.
