[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 、 Figure 2 and Figure 4As shown, this embodiment proposes an upper and lower divided fiber distribution box, including a fiber distribution box 1, the upper and lower sides of the front end of the fiber distribution box 1 are hingedly connected to the trunk optical cable fusion compartment door 2 and the user optical fiber outlet compartment door 3, the inner bottom wall of the fiber distribution box 1 is fixedly connected to the assembly body 4, the first fiber splicing tray 5 is installed on the rear side of the inner wall of the fiber distribution box 1, the inner bottom wall of the fiber distribution box 1 and on the left side of the assembly body 4 are provided with two cable inlets 6, the right side of the inner wall of the fiber distribution box 1 is provided with multiple cable outlets 7, the inside of the fiber distribution box 1 is fixedly connected to a partition 8, and a plug-in optical splitter is installed on the front side of the top of the partition 8 9. A second fiber splicing tray 10 is installed on the rear side of the inner wall of the fiber splitting box 1 and above the partition 8. An optical cable fixing part 11 is installed on the left side of the inner wall of the fiber splitting box 1. Conical sleeves 12 are fixedly connected to the outside of the cable inlet 6 and the cable outlet 7. Water-absorbing material 13 is provided inside the conical sleeve 12. Four fixing feet 14 are fixedly connected to the rear side of the fiber splitting box 1. A mounting frame 15 is provided on the rear side of the fiber splitting box 1. Four card slots 16 are provided on the front side of the mounting frame 15. Two mounting slots 17 are provided inside the mounting frame 15, and fixing components are provided inside the two mounting slots 17. The purpose of this setting is that when in use, the fiber optic box 1 is installed on the wall through the fixing component, the trunk optical cable is passed through the conical sleeve 12 and connected to the cable port 6, passed through the partition 8, and after the optical cable fixing part 11 is limited, the second fiber splicing tray 10 is introduced, and welding and branching are performed, and finally packaged inside, and the pigtail is connected to the input end of the plug-in optical splitter 9, and the optical signal is distributed to multiple optical fibers connected to the output ends according to the distribution ratio. The plug-in optical splitter 9 is used for user access points that require splitting in the system. After splitting, the light enters the end user in the form of user optical fiber, and because the fiber optic box 1 forms upper and lower compartments through the partition 8, the trunk optical cable and user optical fiber can be distributed in order at the upper and lower ends to avoid chaos. The output user optical fiber is then equally divided and embedded into the assembly 4, and connected through the cable outlet 7 and the tapered sleeve 12. The end of the tapered sleeve 12 with a small diameter is an elastic opening, which can better fit the optical cable. When the optical fiber passes through, the elastic opening can tightly wrap the optical cable, further enhancing the sealing between the optical cable and the cable inlet 6 and the cable outlet 7. The water-absorbing material arranged inside it not only fills the gap between the optical cable and the cable inlet 6 and the cable outlet 7, but also prevents dust and mosquitoes from entering the fiber distribution box 1 through these gaps. At the same time, the water-absorbing material is made of super absorbent fiber, which can effectively absorb water vapor in the surrounding environment, and prevent water vapor from entering the fiber distribution box 1 and causing damage to its internal parts.

When the connecting rod 23 rotates, it drives the slider 20 and the card 21 to move toward the middle of the slide rod 18. When the slider 20 moves, it will stretch the spring 19. At this time, the card block 21 releases the restriction on the fixed foot 14, and the fiber distribution box 1 can be removed for maintenance. When the fiber distribution box 1 needs to be installed, the disassembly operation is repeated, and then the fixed foot 14 behind the fiber distribution box 1 is aligned with the card slot 16 in the installation frame 15 and inserted into it, and the pull ring 25 is released. At this time, the connecting rod 23 is reset to drive the moving block 22 to slide. The sliding of the moving block 22 drives the slider 20 to slide to both sides of the fixed rod 18, so that the spring 19 returns to its original state, and then drives the card block 21 to clamp the fixed foot 14, completing the installation of the fiber distribution box 1, avoiding the tediousness of traditional disassembly and installation.
