[0028] Example 1, as Figure 1-4 As shown, the multi-interface fiber optic splitter box includes a bottom shell 1, an outer shell 8, several mounting blocks 4 and several bolts 5. One side of the bottom shell 1 is detachably connected to a hollow connecting tube 3, and one side of the bottom shell 1 is detachably connected to several interface tubes 6. The outer surface of one end of the interface tube 6 is threadedly connected to a cap 7. The inner wall of the bottom shell 1 is detachably connected to a fusion tray 10 with the help of screws. Limit buckles 9 are symmetrically arranged at both ends of one side of the bottom shell 1, and the outer shell 8 is detachably connected to one side of the bottom shell 1 with the help of the limit buckles 9. When using a fiber optic splitter box to split an optical fiber into multiple optical fibers for use, the main optical fiber is usually inserted into the bottom shell 1 and the outer shell 8 through the hollow connecting tube 3, and then the outer skin of the main optical fiber is cut open, and the several secondary optical fibers inside are installed on the fusion splicing tray 10. When the optical fibers need to be connected, the external connecting line can be inserted into the bottom shell 1 through the interface tube 6, and then connected to the secondary optical fibers on the fusion splicing tray 10 for use. Since the fusion splicing tray 10 and the hollow connecting tube 3 and several interface tubes 6 are all detachably connected to the bottom shell 1, when some parts are damaged and need to be replaced, the corresponding damaged parts can be removed and replaced, avoiding the need to replace all the optical fiber splitter boxes, reducing the cost of using the optical fiber splitter box, and facilitating use.

[0029] Reference Figure 1-4 As shown, this embodiment discloses that an adjustment device 2 is provided between the bottom of the bottom shell 1 and several mounting blocks 4, and the adjustment device 2 includes a square frame 23, one side of the square frame 23 is fixedly connected to the bottom of the bottom shell 1, and both sides of the square frame 23 are symmetrically provided with slide grooves 24, one side of the mounting block 4 is fixedly connected with an adjustment rod 21, and the adjustment rod 21 is slidably connected to the slide groove 24, and one side of the adjustment rod 21 is provided with several card slots 22, and both sides of the bottom shell 1 are symmetrically provided with rectangular grooves 25, and one side of the inner wall of the rectangular groove 25 is fixedly connected with a spring 26, and one end of the spring 26 is fixedly connected with a card block 27, and one end of the card block 27 is slidably connected to the rectangular groove 25, and one end of the card block 27 is inserted into the inner wall of the card slot 22. When the bottom shell 1 is installed on the wall for use, the block 27 can be manually slid to a certain position in one end of the rectangular groove 25 according to the reserved installation space and the position of the installation hole, driving the spring 26 to contract, and then one end is pulled out from one of the slots 22, and then the installation block 4 is held and pulled to one end, which can drive the adjustment rod 21 to slide to a certain position in the inner wall of the slide groove 24, so as to be aligned with the reserved installation hole. At this time, the block 27 is released, and under the reset action of the spring 26, one end can be driven to be stuck in the slot 22, and the adjusted adjustment rod 21 is limited and fixed, thereby facilitating the installation of the bottom shell 1 and improving the adaptability of the optical fiber splitter box.

[0030] Reference Figure 1-4As shown, this embodiment discloses that one end of the block 27 has a trapezoidal longitudinal cross-section, and the size of the end of the block 27 away from the spring 26 is smaller than that of the other end. By setting one end of the block 27 to be trapezoidal, the area of one end of the block 27 can be reduced, which facilitates quick alignment and insertion into the inner wall of the slot 22, making it easier to operate. A plurality of rubber strips 28 are fixedly connected to both sides of one end of the block 27, and the plurality of rubber strips 28 are arranged at equal distances. By providing the rubber strips 28, the contact friction force of one end of the block 27 can be increased, so that it is less likely to shake after being inserted into the slot 22, and the insertion is more secure.

[0031] Reference Figure 1-4 As shown, this embodiment discloses a pull block 29 fixedly connected to both sides of one end of the clamping block 27, and a plurality of anti-slip protrusions fixedly connected to both sides of the pull block 29. By providing the pull block 29, the contact friction force on one side of the clamping block 27 can be increased, making it easier to manually grasp and pull it. A telescopic rod 210 is fixedly connected to one side of the inner wall of the rectangular groove 25. One end of the telescopic rod 210 is fixedly connected to one side of the clamping block 27, and the outer surface of the telescopic rod 210 is sleeved and connected to the inner wall of the spring 26. The provision of the telescopic rod 210 can support and reinforce the inner wall of the spring 26, making it less susceptible to damage and increasing the service life of the spring 26.

[0032] Reference Figure 1-4 As shown, this embodiment discloses that the longitudinal cross-section of the adjustment rod 21 is T-shaped, and the longitudinal cross-section of the chute 24 is T-shaped. By setting both the adjustment rod 21 and the chute 24 in a T-shape, the adjustment rod 21 and the chute 24 are less likely to shake during back-and-forth sliding adjustment, and the movement is more stable. A support block 211 is fixedly connected to one side of the mounting block 4. The support block 211 is arranged on the side of the mounting block 4 away from the slot 22. By providing the support block 211, the gap between the mounting block 4 and the bottom of the square bracket 23 can be supported, making it more secure and stable during installation.

[0033] Working principle: when the bottom shell 1 is installed on the wall for use, the block 27 can be manually slid to one end in the rectangular groove 25 to a certain position according to the reserved installation space and the position of the installation hole, driving the spring 26 to contract, and then one end is pulled out of one of the slots 22, and then the installation block 4 is held and pulled to one end, which can drive the adjustment rod 21 to slide to one end in the inner wall of the slide groove 24 to a certain position, which is convenient for aligning with the reserved installation hole. At this time, the block 27 is released, and under the reset action of the spring 26, one end can be driven to be stuck in the slot 22, and the adjusted adjustment rod 21 is limited and fixed, thereby facilitating the installation of the bottom shell 1 and improving the adaptability of the fiber optic splitter box. When multiple optical fibers are used, the main optical fiber is usually inserted into the inside of the bottom shell 1 and the outer shell 8 through the hollow connecting tube 3, and then the outer skin of the main optical fiber is cut open, and the several secondary optical fibers inside are installed on the fusion tray 10. When the optical fibers need to be connected, the external connecting line can be inserted into the inside of the bottom shell 1 through the interface tube 6, and then connected to the secondary optical fibers on the fusion tray 10 for use. Since the fusion tray 10 and the hollow connecting tube 3 and several interface tubes 6 are detachably connected to the bottom shell 1, when some parts are damaged and need to be replaced, the corresponding damaged parts can be removed and replaced, avoiding the need to replace all the optical fiber splitter boxes, reducing the cost of using the optical fiber splitter boxes, and facilitating use.
