Description

Technical Field

[0001] This utility model relates to the field of optical fiber preform preparation technology, and in particular to an optical fiber preform suspension air cooling device. Background Technology

[0002] An optical fiber preform is either a quartz glass rod with a specific refractive index profile used to manufacture optical fibers (optical fibers). The preform typically has a diameter of a few millimeters to tens of millimeters (commonly known as an optical rod), and the internal structure of the optical fiber is formed within the preform.

[0003] When applying for this utility model, a search revealed a Chinese patent that discloses a "fiber optic preform suspension device" with application number "202223343799.3". This patent mainly uses a drive motor to rotate a first gear, which meshes with a second gear, thereby rotating a rotating shaft and causing the hanger to rotate. The sliding wheel slides inside the track, increasing the stability of the hanger during rotation, thus rotating the suspended fiber optic preform. This accelerates the air circulation around the fiber optic preform and increases its air cooling effect. However, when fixing the fiber optic preform, it cannot simultaneously position all the clamps, resulting in low work efficiency. Utility Model Content

[0018] The two ends of the second connecting rod 14 are fixedly connected to the side walls of the mounting rod 8. The two ends of the first connecting rod 9 are slidably connected to the side walls of the mounting rod 8. A second spring 17 is provided inside the mounting rod 8. A first movable block 16 is fixedly connected to the front end of the second spring 17. The side wall of the first movable block 16 is fixedly connected to the side wall of the first connecting rod 9. Each of the multiple fixed rods 6 has a vertical rod 21 on its side wall. A third spring 20 is provided inside each of the multiple vertical rods 21. A second movable block 22 is provided at the lower end of the third spring 20. A ring 7 is slidably connected to the side wall of the multiple vertical rods 21. An insert rod 10 is fixedly connected to the lower end of the ring 7. The two adjacent mounting rods 8 are fixedly connected to each other. A fixed plate 18 is connected, and a horizontal plate 11 is slidably connected to the middle of the fixed plate 18. An insertion hole 19 is opened in the middle of the horizontal plate 11. One end of the horizontal plate 11 is fixedly connected to the side wall of the first connecting rod 9. A first spring 12 is provided inside the first connecting rod 9 and the second connecting rod 14. A limit plate 13 is fixedly connected to the front end of the first spring 12.

[0019] Working principle: In use, the optical fiber preform is placed between two clamps 15. The elasticity of the second spring 17 pushes the first movable block 16 to move, which in turn moves the first connecting rod 9, so that the two clamps 15 clamp and position the optical fiber preform. During the clamping process, the elasticity of the first spring 12 cooperates with the clamps 15. When the optical fiber preform undergoes thermal expansion and contraction, the elastic potential energy generated by the compression of the elastic element will immediately push the pressure ring against the optical fiber preform to prevent it from slipping. Then, the elasticity of the third spring 20 pushes the second movable block 22 to move, which moves the ring 7 and makes the insertion rod 19 cooperate with the insertion hole 19, thereby positioning the first connecting rod 9 and keeping the clamps 15 stable. It can also position multiple clamps 15 at the same time, which is convenient during operation. Motor 2 drives turntable 3 to rotate, which in turn drives the optical fiber preform to rotate. Rotating the suspended optical fiber preform accelerates the air circulation around the optical fiber preform and increases the air cooling efficiency of the optical fiber preform.
