Description

Technical Field

[0001] The utility model relates to the field of optical fiber couplers, in particular to an optical fiber coupler for slope monitoring. Background Art

[0002] Slope monitoring refers to the monitoring of the speed and direction of slope displacement in order to understand the movement of slope rocks and discover signs of slope damage. When monitoring the slope, the movement of slope rocks can be monitored through optical fiber.

[0003] When multiple sections of optical fiber are connected, a fiber optic coupler is required to connect the multiple sections of optical fiber. A fiber optic coupler is also called a splitter, connector, adapter, or fiber optic flange. A fiber optic coupler is a component used to realize the splitting or combining of optical signals, or to extend the optical fiber link. A fiber optic coupler belongs to the field of optical passive components.

For example, if the terrain on the slope to be monitored is complex, it is not convenient to install the fiber optic coupler on the slope with complex terrain, which is not conducive to limiting the position of the fiber optic coupler and will affect the normal use of the fiber optic coupler.

[0035] A first bolt 22 is threadedly inserted in the middle of both ends of the first mounting plate 20 along the vertical direction, and the first bolt 22 is in a vertical state. The first bolt 22 penetrates the upper surface and the lower surface of the corresponding position on the first mounting plate 20, and the first bolt 22 helps to install and limit the first mounting plate 20; a second bolt 23 is threadedly inserted in the middle of both ends of the second mounting plate 21 along the vertical direction, and the second bolt 23 is in a vertical state. The second bolt 23 penetrates the upper surface and the lower surface of the corresponding position on the second mounting plate 21, and the second bolt 23 helps to install and limit the second mounting plate 21.

[0036] The working principle of the utility model is as follows: during use, the lower surfaces of the first mounting plate 20 and the second mounting plate 21 are respectively aligned with the corresponding positions on the slope that need to be monitored by the outside world. When the first mounting plate 20 needs to be rotated and adjusted according to the corresponding position on the slope that needs to be monitored by the outside world, the first mounting plate 20 is rotated along the connecting rod 19 on the optical fiber coupler body 1 through the limiting plate 18, so as to facilitate the rotation and adjustment of the first mounting plate 20 to the corresponding position on the slope that needs to be monitored by the outside world. When the second mounting plate 21 needs to be rotated and adjusted according to the corresponding position on the slope that needs to be monitored by the outside world, the second mounting plate 21 is rotated along the second rotating plate 12 on the second connecting plate 14 through the second fixing plate 10, which helps to rotate and adjust the second rotating plate 12 to the corresponding position on the slope that needs to be monitored by the outside world, so that the lower surfaces of the first mounting plate 20 and the second mounting plate 21 are respectively matched and fitted with the corresponding positions on the slope that needs to be monitored by the outside world.

[0037] The first mounting plate 20 is installed between the corresponding position on the slope that needs to be monitored by the outside world through the first bolt 22. The first bolt 22 can fix and limit the first mounting plate 20 and the various components assembled on the first mounting plate 20, which is convenient for the stable use of the first mounting plate 20 and the various components assembled on the first mounting plate 20. The second mounting plate 21 is installed between the corresponding position on the slope that needs to be monitored by the outside world through the second bolt 23. The second bolt 23 can fix and limit the second mounting plate 21 and the various components assembled on the second mounting plate 21, which is helpful for the stable use of the second mounting plate 21 and the various components assembled on the second mounting plate 21.

[0038] When it is necessary to adjust the installation angle of the optical fiber coupler body 1 according to the arrangement requirements of the external optical fibers, the second rotating ring 6 is rotated by the second protrusion 8. The second protrusion 8 can prevent the outer ring surface of the second rotating ring 6 from slipping, so as to facilitate the stable rotation of the second rotating ring 6. When the second rotating ring 6 rotates, it will move in the vertical direction along the outer side of the threaded screw 15. When the second rotating ring 6 rotates, it will drive the limiting ring 16 to rotate along the connecting tube 17. The limiting ring 16 can limit the position between the second rotating ring 6 and the connecting tube 17. When the second rotating ring 6 rotates, the screw 15 threadedly connected to the second rotating ring 6 will move in the vertical direction along the inner side of the second rotating ring 6. When the screw 15 moves in the vertical direction, it can drive the end of the optical fiber coupler body 1 away from the limiting plate 18 to move in the vertical direction through the first connecting plate 13, the first rotating plate 11 and the first fixed plate 9.

[0039] When the end of the fiber optic coupler body 1 away from the limit plate 18 moves in the vertical direction, the end of the fiber optic coupler body 1 away from the limit plate 18 will rotate along the first connecting plate 13 through the first fixed plate 9 and the first rotating plate 11, and the connecting tube 17 will rotate along the second mounting plate 21 through the second connecting plate 14, the second rotating plate 12 and the second fixed plate 10, so as to rotate the end of the fiber optic coupler body 1 away from the limit plate 18, so that the fiber optic coupler body 1 can be rotated along the limit plate 18 through the connecting rod 19, which is helpful to rotate and adjust the installation angle of the fiber optic coupler body 1.

[0040] After the installation angle of the optical fiber coupler body 1 is adjusted, the protective cover 3 and the optical fiber core 2 are threadedly inserted into the corresponding ends on the optical fiber coupler body 1 through the external threaded tube 4, so that the opposite ends of the optical fiber core 2 are located in the optical fiber coupler body 1 and connected. When the first rotating ring 5 is rotated by the first protrusion 7, the first rotating ring 5 can drive the external threaded tube 4 to rotate, so as to facilitate the assembly or disassembly of the external threaded tube 4. The first protrusion 7 can prevent the outer ring surface of the first rotating ring 5 from slipping, which helps to stably rotate the first rotating ring 5, facilitates the use of the optical fiber coupler body 1, and helps to monitor the slope that needs to be monitored by the outside world through the optical fiber core 2 and the protective cover 3.

[0041] During use, it helps to install the fiber optic coupler body 1 at different locations on the slope that needs to be monitored. For example, if the terrain on the slope that needs to be monitored is complex, the fiber optic coupler body 1 can be conveniently installed on the slope with complex terrain to limit the position of the fiber optic coupler body 1, which helps to use the fiber optic coupler body 1 normally.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
