[0024] The following will be combined with the drawings in 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.

[0025] See also Figure 1-5 The utility model provides the following technical solutions: a device for arranging and positioning multi-core optical fibers, comprising an upper cover plate 1, a lower cover plate 2 being provided at the bottom of the upper cover plate 1, a mounting plate 3 being connected between the upper cover plate 1 and the lower cover plate 2, and a plurality of adapters 4 being provided on the surface of the mounting plate 3;

[0026] The end of the upper cover plate 1 is connected to a fixing block 5, and a slot 6 is opened at the end of the fixing block 5. The end of the lower cover plate 2 is connected to a mounting seat 7. A double-headed screw rod 8 is inserted through one end of the mounting seat 7. The outer wall of the double-headed screw rod 8 is threadedly connected to two threaded connection blocks 9. The tops of the two threaded connection blocks 9 are connected to L-shaped limit plugs 10. A guide rod 11 is provided inside the mounting seat 7.

[0027] Preferably: one end of the double-headed screw 8 forms a rotating connection structure with the mounting seat 7 through a bearing, one end of the two threaded connection blocks 9 is sleeved on the outer wall of the guide rod 11, and the slot 6 is adapted to the size of one end of the L-shaped limit block 10.

[0028] When in use, the two threaded connection blocks 9 on the outer wall of the double-headed screw 8 are rotated counterclockwise so that the two threaded connection blocks 9 can move toward each other along the guide rod 11. As the two threaded connection blocks 9 move toward each other, one end of the L-shaped limit block 10 on the top will be disengaged from the slot 6 at the end of the fixed block 5. At this time, the upper cover 1 and the lower cover 2 can be separated, thereby improving the convenience of disassembly and maintenance of the device.

[0029] On the contrary, during assembly, by docking the upper cover plate 1 and the lower cover plate 2, the fixing blocks 5 at both ends will be placed on the top of the mounting seat 7, and then by rotating the double-headed screw 8 clockwise, the two threaded connection blocks 9 on the outer wall can move toward each other along the guide rod 11. As the threaded connection block 9 moves, one end of the L-shaped limit block 10 is inserted into the slot 6 at the end of the fixing block 5, thereby achieving assembly and fixation.

[0030] Preferably: the surface of the mounting plate 3 is connected to a fixed frame 12, a protective cover 13 is provided on the inner side of the fixed frame 12, the end of the protective cover 13 is connected to a slider 14, a slide groove 15 is provided on the outer wall of the fixed frame 12, and a magnetic block 16 is provided on the inner top of the fixed frame 12. The protective cover 13 can form a sliding connection structure with the fixed frame 12 through the slider 14 and the slide groove 15. The material of the protective cover 13 is iron, and the magnetic block 16 is located directly above the protective cover 13.

[0031] During specific use, the protective cover 13 is pulled by the shift block so that it rises along the slide groove 15 under the action of the slider 14. When the iron protective cover 13 rises, it will be attracted and fixed by the magnetic block 16. At this time, the adapter 4 is connected to the wire. After the wire is pulled out, the protective cover 13 is pulled down by the shift block to protect the connection of the adapter 4, thereby avoiding damage to the connection of the adapter 4.

[0032] Working principle: First, when the internal part of the device needs to be disassembled and maintained, the two threaded connection blocks 9 on the outer wall are rotated counterclockwise so that they can move toward each other along the guide rod 11. As the two threaded connection blocks 9 move toward each other, one end of the top L-shaped limit block 10 will be disengaged from the slot 6 at the end of the fixed block 5. At this time, the upper cover 1 and the lower cover 2 can be separated, thereby improving the convenience of disassembly and maintenance of the device, and the protective cover 13 is pulled by the shift block to rise along the slide groove 15 under the action of the slider 14. When the iron protective cover 13 rises, it will be attracted and fixed by the magnetic block 16. At this time, the adapter 4 is connected to the wire. After the wire is pulled out, the protective cover 13 can be pulled down by the shift block to protect the connection of the adapter 4, thereby avoiding damage to the connection of the adapter 4.
