The protective shell 1 provides overall support and protection for the fiber optic distribution box, ensuring that the internal components are protected from the influence of the external environment, including physical damage, dust and moisture. The split layer 2 is used to separate and organize the optical fiber connection, and provides the function of hierarchical management of optical fiber connections and modules. The layered design makes the management and maintenance of optical fibers more orderly and convenient, improves operational efficiency, and reduces the risk of optical fiber crossing and entanglement. The protective plate 5 is connected to one end of the protective shell 1 by rotation, and is used to close the wiring box when not in use to prevent damage to internal components. The MPO module box 3 is used to accommodate and fix the optical fiber adapter, and provides organization and management of optical fiber connection points. The MPO module box 3 is fixed by embedding the first fixing protrusion 32 on the first elastic member 31 into the first fixing groove 21. When disassembling, move the first elastic member 31 to separate the first fixing protrusion 32 from the first fixing groove 21. The MPO module box 3 is easier to install and replace through a detachable modular design, with high flexibility and easy system expansion and maintenance. The duplex adapter 4 is fixed in the MPO module box 3 to achieve docking of optical fiber connections. The protective housing 1 of this embodiment has a width of 19 inches and a height of 1U, which meets the conventional rack installation standards. In this embodiment, three partition layers 2 are arranged in the standard protective housing 1, and each partition layer 2 is provided with four MPO module boxes 3. Each MPO module box 3 is provided with 6 duplex adapters 4, and each duplex adapter 4 can connect two optical fiber ports. The optical fiber distribution box of this embodiment can connect up to 144 optical fiber ports. The 144 optical fiber ports allow users to connect more optical fibers in a limited space, and the modular MPO module box 3 allows users to install an appropriate number of MPO module boxes 3 according to direct needs.

[0028] In this embodiment, the push-out structure includes three pairs of spring groups and two fixed plates 11. The two fixed plates 11 are respectively located on both sides of the protective shell 1. The spring group includes two compression springs 12. The two compression springs 12 are respectively fixedly connected to the two fixed plates 11. The compression springs 12 extend toward the partition layer 2. One end of the two compression springs 12 in the same group away from the fixed plate 11 abuts against the same partition layer 2. The partition layer 2 is provided with a limiting structure for fixing the position of the partition layer 2. The fixed plate 11 is used to fix one end of the spring group and provide a stable support point. The three pairs of spring groups correspond to the three partition layers 2 respectively, and each partition layer 2 corresponds to a group of spring groups. The compression spring 12 is used to generate elastic force after being compressed to push out the partition layer 2. When the partition layer 2 is located in the protective shell 1, the compression spring 12 is compressed. At this time, the compression spring 12 generates elastic force. When the limiting structure no longer limits the partition layer 2, the compression spring 12 applies elastic force to the partition layer 2 to eject the compression spring 12, thereby ejecting the partition layer 2.

[0029] In this embodiment, the guide rail structure includes two first slide grooves 13, two second slide grooves 22, two first pulleys 14, and two second pulleys 23; the two first slide grooves 13 are located on both sides of the protective shell 1, the two second slide grooves 22 are located on both sides of the partition layer 2, the two first pulleys 14 are located on both sides of the protective shell 1 and are rotatably connected to the protective shell 1, the first pulley 14 is close to the protective plate 5, the first slide groove 13 is far away from the protective plate 5, the two second pulleys 23 are located on both sides of the partition layer 2 and are rotatably connected to the partition layer 2, the second pulley 23 is far away from the protective plate 5, the second slide groove 22 is close to the protective plate 5, the first pulley 14 is embedded in the second slide groove 22, and the second pulley 23 is embedded in the first slide groove 13. The first slide groove 13 provides a sliding track for the second pulley 23, and the first slide groove 13 provides a stable sliding path for the second pulley 23, ensuring that the partition layer 2 can move smoothly during operation. The second slide groove 22 provides a sliding track for the first pulley 14, and the second slide groove 22 provides a precise sliding path for the first pulley 14, ensuring smooth sliding between the protective shell 1 and the partition layer 2. The design of the first slide groove 13 and the second slide groove 22 helps to ensure that the partition layer 2 is accurately positioned during sliding, reduce the friction generated during the sliding process, and extend the service life of the equipment. The rotation characteristics of the first pulley 14 and the second pulley 23 ensure the stability of the partition layer 2 during sliding and reduce the jamming phenomenon caused by friction.

The second fixing protrusion 26 is embedded in the second fixing groove 15 to achieve the fixing effect of the second elastic member 24, thereby achieving the effect of limiting the position of the partition layer 2.

[0031] In this embodiment, the protective housing 1 is provided with a first upper cover plate 6, which is located at the upper end of the protective housing 1, one end of the first upper cover plate 6 abuts against the protective plate 5, and one end of the first upper cover plate 6 that is away from the protective plate 5 extends toward the middle of the protective housing 1.
