Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber communication equipment, and specifically relates to a high-density optical fiber distribution box. Background Technique

[0002] An optical fiber distribution box is a device used to manage and distribute optical fiber lines, usually installed in a wall or a floor-standing cabinet. It provides optical fiber access points, facilitating the connection, distribution, and management of multiple optical fiber lines, and supports functions such as optical fiber fusion splicing, transfer, and testing to ensure the quality and efficiency of network signal transmission. In modern communication networks, especially in the FTTH (Fiber To The Home) system, the optical fiber distribution box plays a crucial role.

[0003] In the Chinese patent document "CN216351428U, a modular optical fiber distribution box and a composite optical fiber module box", elastic locking pieces are fixedly arranged on the left and right side walls of the bottom box, an independent layer board for a layered module box is installed inside the bottom box, and the module box is independently a three-layer structure; a plastic track for sliding the module box is also arranged on the independent layer board. During installation, the independent layer board is slid into along the plastic track, and then the independent layer board is fixed through the cooperation of the elastic locking piece and the screw.

[0004] Although the above technology can stably install the independent layer board, the installation steps are cumbersome, resulting in an increase in installation and disassembly time, and there is a lack of shockproof measures. Once affected by external impacts, the internal optical fiber connections may become loose, affecting the communication quality. Content of the Utility Model

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figures 1-7 ;

[0029] A high-density optical fiber distribution box, comprising a housing 1, with door panels 2 rotatably connected to both ends of the housing 1. By simply flipping the door panels 2, it is convenient to quickly access and maintain the internal equipment, improving the efficiency of work and maintenance. Inside the housing 1, there is a fixing rack 3. On the fixing rack 3, a number of first positioning blocks 31 are vertically arranged. At one end far from the fixing rack 3, support assemblies 4 are symmetrically provided. Vertically upwards on the inner sides of the support assemblies 4, a number of limiting chutes 46 are provided. A fixing plate 5 for installing a fiber optic splice tray 51 is inserted through the cooperation of the two-sided limiting chutes 46. In order to prevent the distribution box from accidentally colliding with the housing 1, anti-slip pads can be added to the upper and lower inner walls of the limiting chutes 46. The anti-slip pads can increase the friction force, thus effectively preventing the fixing plate 5 from moving unnecessarily when subjected to external impacts, protecting the internal components from damage. One end of the fixing plate 5 close to the fixing rack 3 is provided with a mounting hole 52 for inserting a mounting block 53. Inside the mounting block 53, a second positioning block 54 corresponding to the first positioning block 31 is movably connected, for the positioning and installation of the tray. Here, it should be noted that the shape of the first positioning block 31 is similar to an arrow, and the second positioning block is in a V-shaped that can wrap the first positioning block 31. During the installation process of the fixing plate 5, if there are deviations or misalignments in the initial position, its inclined surface plays an automatic correction role, prompting the fixing plate 5 to gradually slide into the correct position. At the same time, it also avoids the problem of the fixing plate 5 shaking when the distribution box is collided. A spring 55 is provided between the second positioning block 54 and the mounting block 53, for buffering the fixing plate 5. When the distribution box encounters an accidental collision, the spring 55 can absorb part of the impact energy, thus reducing the direct impact of the fixing plate 5 on the fixing rack 3, protecting the internal structure of the fusion splicing tray from damage, and extending the service life of the equipment.

[0030] In this embodiment, a limiting hole 531 is provided at the top of the mounting block 53, and a limiting block 541 embedded in the limiting hole 531 is provided on the second positioning block 54, for preventing the second positioning block 54 from being ejected from the mounting block 53 by the spring 55. At the same time, through the restraint of the limiting hole 531 on the limiting block 541, it can also prevent the limiting block 541 from sliding and shifting.

[0031] In this embodiment, the mounting block 53 includes a plugging part 532 for inserting into the fixing rack 3. At one end of the plugging part 532 outside the fixing rack 3, a clamping part 533 is provided. On both sides of the plugging part 532 inside the fixing rack 3, outward pressing parts 534 are provided. The mounting block 53 is clamped on the fixing rack 3 through the cooperation of the outward pressing parts 534 and the clamping part 533. During installation, only need to push the plugging part 532 into the mounting hole 52. After insertion, the clamping part 533 will abut against the outer side surface of the fixing plate 5. At this time, the two outward parts are located inside the fixing plate 5, and the distance between the two outward parts at one end of the mounting hole 52 is greater than the length of the mounting hole 52, which can prevent the mounting block 53 from falling off. When disassembling and replacing the mounting block 53, only need to press the outward pressing parts 534 inward, and the mounting block 53 can be directly pulled out.

[0032] In this embodiment, the bracket assembly 4 includes a number of stacking-mounted carriers 41. The carrier 41 is provided with an upper support portion 42 and a lower support portion 43. Both the upper support portion 42 and the lower support portion 43 extend horizontally and are used to support each carrier 41. The upper support portion 42 is provided with a jack 44, and the lower support portion 43 is provided with a plug 45 for inserting into the jack 44 to ensure the stable use of the carrier 41.

[0033] Specifically, the plug 45 is an L-shaped plug 45. The jack 44 includes an insertion end 441 and a clamping end 442. The width of the insertion end 441 is greater than that of the clamping end 442, which is convenient for the plug 45 to be inserted. The width of the clamping end 442 is adapted to that of the plug 45, so that the plug 45 can be clamped tightly. During installation, the plug 45 is inserted downward into the insertion end 441, and then the upper carrier 41 is pushed inward to make the plug 45 snap into the clamping end 442. At the same time, in order to further enhance the stability of the carrier 41, a fixing column is inserted at the end of the mutually installed carriers 41 to limit the front-back displacement of the carrier 41. A round block is rotatably connected to the upper part, and the round block abuts against the upper end surface of the lower support portion 43 to limit the up-down displacement of the carrier 41 and improve the stability of the use of the carrier 41.

[0034] In this embodiment, a number of hooks 32 are vertically distributed on both sides of the fixing frame 3. The hooks 32 can be used to hang the cables connected to the fiber optic splice tray 51 to improve the aesthetics inside the distribution box.

[0035] In this embodiment, both ends of the bottom of the housing 1 are respectively hinged to two door panels 2 through hinges. Both ends of the top of the housing 1 are provided with bending portions 11. The door panel 2 is provided with a door buckle 21 that can be pushed up and down. One end of the door buckle 21 is provided with an inverted buckle 22 that abuts against the bending portion 11. Just push the door buckle 21 up or down to close or open the door panel 2.
