[0003] A search revealed that Chinese utility model patent application number CN202323248575.9 discloses an expansion device for an optical cable junction box, including an expansion box installed on the optical cable junction box. The expansion box has an opening on one side of the optical cable junction box and is installed on the optical cable junction box by a connector. The expansion box contains multiple support assemblies, each of which is equipped with several optical splitter frames for placing additional equipment.

[0004] The optical splitter assembly is installed inside the expansion box, and the splitter and other equipment are placed inside the optical splitter assembly. When disassembling or assembling the optical splitter and other equipment inside the optical splitter assembly, people need to reach into the expansion box and then into the optical splitter assembly to disassemble or assemble the equipment. This is inconvenient for people to operate. At the same time, the optical splitter assembly is installed inside the expansion box with a lot of screws, which makes it difficult to disassemble the optical splitter assembly. Therefore, it is not convenient to disassemble or assemble the optical splitter and other equipment inside the optical splitter assembly, which affects the efficiency of its maintenance and replacement and reduces its practicality.

[0031] Please see Figures 1-6 An expansion device for an optical cable junction box includes an expansion box 1 and an optical splitter assembly 2. The expansion box 1 is connected to a box cover 23 to cover the opening of the expansion box 1. An installation base 3 is slidably arranged inside the expansion box 1. The installation base 3 is provided with a connecting groove 4. Two sliding grooves 5 are provided on the side end of the connecting groove 4. Slide plates 6 are slidably arranged inside the two sliding grooves 5. Screws 7 are threadedly connected to the positions of the two sliding grooves 5 on the installation base 3. A throttle 22 is fixedly connected to the side end of the screw 7 to facilitate the rotation of the screw 7. The side end of the screw 7 is rotatably connected to the side end of the slide plate 6. A retaining plate 8 is fixedly connected to the side end of the slide plate 6. A connecting seat 9 is fixedly connected to the bottom end of the optical splitter assembly 2. The connecting seat 9 is inserted into the interior of the connecting groove 4. A retaining groove 10 is provided on the side end of the connecting seat 9 at the positions corresponding to the two sliding grooves 5. The two retaining plates 8 are respectively inserted into the two retaining grooves 10.

[0032] Specifically, by rotating the screw 7 counterclockwise, the screw 7 drives the slide plate 6 to move away from the connecting groove 4, so that the card plate 8 separates from the card groove 10, making it easier to pull the connecting seat 9 out of the connecting groove 4. Compared with disassembling the optical splitter assembly 2 by removing multiple screws, this method is more convenient for disassembling the optical splitter assembly 2, making it easier to move the optical splitter assembly 2 to the outside of the expansion box 1, and making it easier to disassemble and assemble the optical splitter and other equipment inside the optical splitter assembly 2. This ensures the efficiency of maintenance and replacement of the optical splitter and other equipment inside the optical splitter assembly 2, and improves its practicality.

[0033] Please see Figure 1 , Figure 3 and Figure 5 The expansion box 1 has a convex groove 11 inside, and a convex component is slidably arranged inside the convex groove 11. The mounting base 3 is connected to the convex component by a plurality of first screws 12. The connecting groove 4 has a plurality of first countersunk grooves 13 inside, and the screw heads of the plurality of first screws 12 are respectively located inside the plurality of first countersunk grooves 13, so that the screw heads of the first screws 12 are hidden inside the first countersunk grooves 13, ensuring the flatness of the bottom of the connecting groove 4.

[0034] Specifically, by sliding the convex component inside the convex groove 11, it is easy to adjust the position of the mounting base 3 inside the expansion box 1, and to make appropriate adjustments to the position of the optical splitter assembly 2 connected to the mounting base 3, so as to move the optical splitter assembly 2 to a suitable position inside the expansion box 1 as needed.

[0035] Please see Figure 1 , Figure 3 and Figure 5 The convex component includes two slide blocks 14 and an intermediate seat 15. Both slide blocks 14 are slidably engaged with the convex groove 11. The intermediate seat 15 is connected to the mounting base 3. Two slots 16 are symmetrically arranged on the intermediate seat 15. Insert plates 17 are inserted into the interior of each slot 16. The two insert plates 17 are fixedly connected to the two slide blocks 14 respectively. Multiple second screws 18 that mate with the insert plates 17 are threaded onto the intermediate seat 15 to facilitate assembly. Multiple second countersunk grooves 19 are provided on the intermediate seat 15. The screw heads of the multiple second screws 18 are located inside the multiple second countersunk grooves 19 to hide the screw heads inside the second countersunk grooves 19 and ensure the flatness of the surface of the intermediate seat 15. Multiple fixing grooves 20 are evenly arranged at the bottom end of the convex groove 11. A third screw 21 is threaded onto the intermediate seat 15 and is inserted into the corresponding fixing groove 20 to facilitate fixing the intermediate seat 15.

[0036] Specifically, insert plate 17 is inserted into slot 16 and fixedly connected to intermediate seat 15 by tightening second screw 18, which facilitates the assembly and disassembly of convex component, facilitates the assembly and installation of convex component inside convex groove 11, facilitates its disassembly, and facilitates its removal from inside convex groove 11, thus facilitating the assembly and disassembly of convex component.

[0037] In summary, when using the overall equipment:

[0038] First, insert the two slide blocks 14 into the two sides of the convex groove 11. Then, insert the intermediate seat 15 into the convex groove 11. Next, insert the two insert plates 17 into the two slots 16 on the intermediate seat 15. Then, tighten the second screw 18 so that the side end of the second screw 18 abuts against the side end of the insert plate 17, thus fixing the insert plate 17 to the intermediate seat 15. Then, move the intermediate seat 15 to the appropriate position by sliding the two slide blocks 14 with the convex seat. Finally, tighten the third screw 21 so that the third screw 21 is inserted into the slot 16. Inside the corresponding fixing slot 20, the intermediate seat 15 is fixed, and then the mounting seat 3 is installed and fixed on the intermediate seat 15 by multiple first screws 12. Then, the connecting seat 9 on the optical splitter frame with the optical splitter and other equipment is inserted into the inside of the mounting slot. Then, the two screws 7 are rotated clockwise, and the two screws 7 respectively drive the two slide plates 6 to move towards the side closer to the connecting seat 9, and the card plate 8 is inserted into the inside of the slot 16, fixing the connecting seat 9 inside the connecting slot 4, thereby installing the optical splitter frame assembly 2 inside the expansion box 1.

[0039] When it is necessary to disassemble, repair, or replace equipment such as optical splitters inside the optical splitter frame assembly 2, turn the screw 7 counterclockwise. The screw 7 will drive the slide plate 6 to move away from the connecting groove 4, so that the card plate 8 is separated from the card groove 10. Then, pull the connecting seat 9 out of the connecting groove 4, move the optical splitter frame assembly 2 to the outside of the expansion box 1, and then disassemble, repair, or replace equipment such as optical splitters inside the optical splitter frame assembly 2.
