[0026] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

FIG8 is a schematic diagram of a high-density optical fiber bundle and a ceramic adhesive coating provided by an exemplary embodiment of the present application. As shown in Figure 1‑8, an optical fiber bundle airtight sealing device includes a fixing seat 1, a conduit 11 is fixedly installed on the top of the fixing seat 1, a locking assembly is provided inside the conduit 11, a mounting seat 2 is fixedly installed on the top of the conduit 11, a turntable 21 is provided inside the mounting seat 2, a shell 3 is provided above the turntable 21, an optical fiber bundle light guide assembly is provided inside the shell 3, the turntable 21 is rotatably connected to the inner wall of the groove of the mounting seat 2, the locking assembly limits and fixes the turntable 21, an adjustment assembly is provided inside the mounting seat 2, and the direction of the turntable 21 is adjusted by the adjustment assembly, the top of the turntable 21 is fixedly installed on both sides of the shell 3, and the adjustment frame 39 is rotatably connected to the shell 3, and a damping member is provided at the connection between the adjustment frame 39 and the shell 3, and the damping member is used to prevent the rotation between the adjustment frame 39 and the shell 3.

[0029] In the embodiment of the present application, since the existing optical fiber bundle light-guiding equipment usually adopts manual movement adjustment when adjusting the light direction, the adjustment angle accuracy is difficult to control, and the adjusted direction is not easy to limit and fix, the optical fiber bundle light-guiding component is driven to rotate by the turntable 21 and the adjustment frame 39, so that the light direction of the optical fiber bundle light-guiding component can be accurately adjusted.

[0030] Specifically, a conduit 11 is fixedly installed on the top of the fixing seat 1, and a locking assembly is provided inside the conduit 11. The conduit 11 is a hollow structure. A mounting seat 2 is fixedly installed on the top of the conduit 11, and a turntable 21 is provided inside the mounting seat 2. A shell 3 is provided above the turntable 21, and a fiber optic bundle light guide assembly is provided inside the shell 3. The turntable 21 is rotatably connected to the inner wall of the groove of the mounting seat 2, and the turntable 21 is limited and fixed by the locking assembly. An adjustment assembly is provided inside the mounting seat 2, and the adjustment assembly adjusts the direction of the turntable 21. It can be understood that the fixing seat 1 and the conduit 11 support the mounting seat 2, a turntable 21 is provided inside the mounting seat, a shell 3 is provided above the turntable 21, and a fiber optic bundle light guide component is provided inside the shell 3. The turntable 21 is rotatably connected to the inner wall of the groove of the mounting seat 2, so that the turntable 21 is driven to rotate through the adjustment component, and then the turntable 21 can drive the shell 3 to rotate in a circle, and then the fiber optic bundle light guide component performs a circular motion around the mounting seat 2. Therefore, since the turntable 21 drives the light beam light guide component to rotate in different directions, the direction of the light is different.

[0031] For the sake of stability in use, the turntable 21 is limited and fixed by a locking assembly, thereby preventing the turntable 21 from accidentally rotating during use, which would cause the direction of the light beam to change.

[0032] In addition, in order to be able to more accurately adjust the orientation direction of the light beam light guide assembly, an adjustment frame 39 is fixedly installed on both sides of the top of the turntable 21, and the adjustment frame 39 is rotatably connected to the outer shell 3. In other words, the adjustment frame 39 can adjust the outer shell 3 to rotate on the turntable 21. Since the diameter of the outer shell 3 is smaller than the diameter of the turntable 21, the light beam direction of the light beam light guide assembly can be fine-tuned. First, the light beam direction of the light beam light guide assembly can be roughly adjusted through the adjustment assembly, and then the light beam direction of the light beam light guide assembly can be fine-tuned through the adjustment frame 39, thereby ensuring that the light beam direction of the light beam light guide assembly is more accurate and the accuracy of the adjustment angle can be more easily controlled. Finally, the damping member is used to prevent the rotation between the adjustment frame 39 and the outer shell 3, thereby preventing the deviation of the outer shell 3 during use from causing the light beam direction to shift. Modes for Carrying Out the Invention

[0033] The present application provides an airtight sealing device for an optical fiber bundle, comprising a fixing seat, a catheter fixedly mounted on the top of the fixing seat, a locking assembly provided inside the catheter, a mounting seat fixedly mounted on the top of the catheter, a turntable provided inside the mounting seat, a housing provided above the turntable, an optical fiber bundle light guide assembly provided inside the housing, the turntable being rotatably connected to the inner wall of a groove of the fixing seat, the locking assembly limiting and fixing the turntable, an adjustment assembly provided inside the fixing seat, the adjustment assembly adjusting the direction of the turntable, an adjustment frame fixedly mounted on the top of the turntable on both sides of the housing, the adjustment frame being rotatably connected to the housing, a damping member provided at the connection between the adjustment frame and the housing, the damping member being used to prevent rotation between the adjustment frame and the housing. The direction of the optical fiber bundle light guide assembly is precisely adjusted by the turntable and the adjustment frame, and the turntable and the adjustment frame are limited by the locking device and the damping member, thereby ensuring stability in use.

[0034] As shown in Figure 2‑3, the adjustment assembly includes a gear ring 22 and first gears 23 provided on both sides of one side of the inner wall of the gear ring 22, the top of the gear ring 22 is fixedly connected to the bottom end of the turntable 21, and a first knob 25 is provided on one side of the bottom end of the mounting base 2, the top of the first knob 25 is fixedly connected to the first gear 23, the first gear 23 is engaged with the gear ring 22, and the first knob 25 drives the first gear 23 to rotate synchronously around the gear ring 22 to adjust the direction of the turntable 21.

[0035] A second knob 26 is provided on the other side of the bottom end of the mounting base 2, and a second gear 24 is provided on the other side of the inner wall of the gear ring 22. The number of teeth of the first gear 23 is greater than the number of teeth of the second gear 24. The second gear 24 is engaged with the gear ring 22. The top end of the second knob 26 is fixedly connected to the second gear 24. The second knob 26 drives the second gear 24 to rotate synchronously around the gear ring 22 to adjust the direction of the turntable 21. The angle of the turntable 21 adjusted by the second gear 24 is smaller than the angle of the turntable 21 adjusted by the first gear 23.

[0036] In an embodiment of the present application, in order to further improve the rotation accuracy of the turntable 21, the direction of the turntable 21 is adjusted by meshing the first gear 23, the second gear 24 and the gear ring 22, wherein the first gear 23 and the second gear 24 have different sizes and numbers of teeth, and the accuracy of the rotation of the turntable 21 driven by the first gear 23 and the second gear 24 is different. The larger the gear size and the number of teeth of the first gear 23 and the second gear 24, the smaller the turntable rotation accuracy, thereby accurately adjusting the light beam direction of the optical fiber bundle light guide assembly.

[0037] In order to facilitate the operation of the operator, the first gear 23 and the second gear 24 can be driven to rotate by the first knob 25 and the second knob 26, so as to adjust the rotation direction of the turntable 21.

[0038] As shown in Figure 3‑4, the locking mechanism includes an inner rod 15 arranged inside the catheter 11, and the inner rod 15 is movably connected to the inner wall of the catheter 11. A chuck 17 is provided at the inner center of the mounting seat 2. The top end of the inner rod 15 passes through the bottom surface of the mounting seat 2 and is fixedly connected to the bottom outer surface of the chuck 17. A slot 27 matching the chuck 17 is provided at the center of the bottom outer surface of the turntable 21. When the chuck 17 is inserted into the slot 27 and the chuck 17 is stationary in the slot 27, the turntable 21 is limited and fixed.

[0039] In the embodiment of the present application, in order to limit and fix the turntable 21, the chuck 17 set in the inner center of the mounting base 2 and the clamping groove 27 in the center of the bottom outer surface of the turntable 21 are matched to limit and fix the turntable 21.

[0040] Specifically, when the turntable 21 needs to be limited and fixed, the inner rod 15 is rotated, and the inner rod 15 drives the chuck 17 set in the center of the mounting base 2 to move toward the turntable 21. Then, when the chuck 17 is connected to the slot 27 in the center of the bottom outer surface of the turntable 21, the turntable 21 is limited and fixed.

[0041] As shown in Figure 3‑4, a ring 13 is provided on the outer surface of the catheter 11, and a slide groove 12 is opened in the catheter 11. The slide groove 12 extends along the axial direction of the chuck. Sliders 14 are connected on both sides of the inner wall of the ring 13. The sliders 14 match the slide groove 12. The ring 13 is connected to the outer surface of the inner rod 15 through one end of the slider 14. A first return spring 16 is provided inside the catheter 11. The top end of the first return spring 16 is connected to the bottom end of the inner rod 15. The ring 13 drives the inner rod 15 to slide along the extension direction of the slide groove 12 to make the chuck 17 move away from or close to the turntable 21.

[0042] In the embodiment of the present application, in order to facilitate the movement of the inner rod 15 toward or away from the turntable 21, the slider 14 can be driven by the ring 13 to slide along the sliding direction of the slide groove 12, and then the slider 14 drives the inner rod 15 to move toward or away from the turntable 21.

[0043] Specifically, the outer surface of the catheter 11 is provided with a collar 13. A slot 12 is defined on the outer surface of the catheter 11, located inside the collar 13. Sliders 14 are connected to both sides of the inner wall of the collar 13. The slides 14 are inserted into the slots 12, and the collar 13 is connected to the outer surface of the inner rod 15 via one end of the slider 14. It is understood that the slider 14 is fixedly connected to the inner rod 15, and the slider 14 and collar 13 are integrally formed. Movement of the collar 13 drives movement of the slider 14, which in turn drives movement of the inner rod 15. A slot 12 is defined on the outer surface of the catheter 11. The slider 14 is disposed within the slot 12 and slides along the sliding direction of the slot 12.

[0044] Furthermore, to further secure the chuck 17 within the slot 27, a first return spring 16 can be provided at the bottom end of the inner rod 15. The top end of the first return spring 16 is in contact with the bottom end of the inner rod 15. When the chuck 17 is removed from the slot 27, the first return spring 16 is subjected to a compressive force and moves away from the turntable 21. When the chuck 17 approaches the slot 27, the compressive force allows the first return spring 16 to quickly return to its original position, further securing the chuck 17 to the slot 27.

[0045] The outer surface of chuck 17 can be configured as a gear, and the outer surface of slot 27 can be configured as a gear, with chuck 17 and slot 17 meshing with each other. Because the gear of chuck 17 is fixed within the gear of slot 27, chuck 17 cannot rotate around slot 27. Therefore, a gear-shaped fixation between chuck 17 and slot 27 is more secure than a smooth one. The inner walls of collar 13 can be integrally formed with slider 14 on both sides, and collar 13, slider 14, and inner rod 15 can be integrally formed.

[0046] As shown in Figure 5, the optical fiber bundle airtight sealing device can also include a moving device, which passes through the outer shell 3. An inner cylinder 31 is provided inside the outer shell 3. The inner cylinder 31 moves along the axis of the outer shell 3. An optical fiber bundle light guide component is provided inside the inner cylinder 31. An adjustment groove 32 is provided on the outer surface of one side of the inner cylinder 31. One end of the moving device is provided inside the adjustment groove 32. The moving device drives the inner cylinder 31 to slide along the extension direction of the adjustment groove 32.

[0047] In the embodiment of the present application, in order to adjust the height of the optical fiber bundle light guide assembly, the inner cylinder 31 is driven up and down by the third gear 36 to adjust the height of the optical fiber bundle light guide assembly.

[0048] Specifically, an adjustment groove 32 is opened on the outer surface of one side of the inner cylinder 31, and the inner wall of the adjustment groove 32 is integrally connected with a latch tooth. A third gear 36 is provided inside the adjustment groove 32, and the third gear 36 is meshed with the latch tooth. The third gear 36 drives the inner cylinder 31 to slide along the sliding direction of the adjustment groove 32, wherein the inner wall of the adjustment groove 32 and the latch tooth are integrally formed.

[0049] As shown in Figure 5‑6, the moving device includes a connecting shaft 35, a third gear 36, a rotating drum and a knob 34. The inner wall of the adjusting groove 32 is connected with a latch tooth. The third gear 36 is arranged inside the adjusting groove 32, and the third gear 36 is meshed with the latch tooth. A rotating groove 33 is opened on the outer surface of one side of the shell 3. The knob 34 and the rotating drum are in contact with the inner wall of the rotating groove 33. One end of the connecting shaft 35 is fixedly connected to one end of the rotating drum, and the other end of the connecting shaft 35 is fixedly connected to the third gear 36. The other end of the rotating drum is fixedly connected to the knob 34. The knob 34 drives the rotating drum to rotate in the rotating groove 33, and the rotating drum drives the connecting shaft 35 to rotate. The rotation of the connecting shaft 35 drives the third gear 36 to rotate in the adjusting groove 32, so that the inner drum 31 slides along the extension direction of the adjusting groove 32.

[0050] In the embodiment of the present application, in order to facilitate the operator to adjust the third gear 36, thereby adjusting the height of the optical fiber bundle light guide assembly, the knob 34 and the rotating groove 33 are rotated, and then the third gear 36 engages with the teeth on the inner wall of the adjustment groove 32 and drives the inner cylinder 31 to slide along the sliding direction of the adjustment groove 32, thereby adjusting the height of the optical fiber bundle light guide assembly.

[0051] As shown in Figure 6‑7, a limiting assembly is provided inside the rotating knob 34, and a first groove, a second groove and a third groove are provided inside the rotating knob 34, and the first groove is connected to the second groove and the third groove in sequence. The limiting assembly includes a pressure rod 341, a connecting plate 342, a limiting rod 343 and a second return spring 344. The pressure rod 341 contacts the inner wall of the first groove of the rotating knob 34, and the outer surface of one end of the pressure rod 341 is connected to the connecting plate 342, the connecting plate 342 contacts the inner wall of the second groove, and one end of the connecting plate 342 is connected to the limiting rod 343, and the limiting rod 343 contacts the inner wall of the third groove. A second return spring 344 is provided in the first groove, one end of the second return spring 344 contacts the inner wall of the first groove, and the other end of the second return spring 344 contacts one end of the pressure rod 341, and the inner wall of the rotating groove 33 is provided with multiple limiting grooves matching one end of the limiting rod 343.

[0052] In the embodiment of the present application, since the height of the optical fiber bundle light guide assembly can be adjusted by the knob 34, but after adjusting the height of the optical fiber bundle light guide assembly, the optical fiber bundle light guide assembly needs to be limited to ensure the stability of the operation, the optical fiber bundle light guide assembly can be limited by matching the multiple limiting grooves on the inner wall of the rotation groove 33 with one end of the limiting rod 343.

[0053] Specifically, a limit assembly is provided within the knob 34. The limit assembly includes a pressure rod 341 that contacts the inner wall of the first groove of the knob 34. One end of the pressure rod 341 is integrally formed with a connecting plate 342. The connecting plate 342 contacts the inner wall of the second groove of the knob 34. One end of the connecting plate 342 is integrally formed with a limit rod 343. The limit rod 343 contacts the inner wall of the third groove of the knob 34. The first groove is sequentially connected to the second groove and the third groove. Pressing the pressure rod 341 simultaneously drives the limit rod 343 inward.

[0054] The inner wall of the rotating groove 33 is provided with multiple limiting grooves matching one end of the limiting rod 343. A second return spring 344 is provided in the first groove. One end of the second return spring 344 contacts the inner wall of the first groove, and the other end of the second return spring 344 contacts one end of the pressure rod 341.

[0055] That is to say, when the pressure rod 341 is pressed, the limit rod 343 also moves inward at the same time, and then the height of the optical fiber bundle light guide assembly is adjusted at the same time. When the height is determined, the pressure rod 341 is released, and the second return spring 344 drives the limit rod 343 and the pressure rod 341 to move outward due to the extrusion force. At the same time, the limit rod 343 matches the limit groove, thereby preventing the knob 34 from moving in the groove 33, thereby limiting and fixing the optical fiber bundle light guide assembly.

[0056] As shown in Figures 2 and 5, a guide groove 391 is provided on the outer surface of the outer shell 3, and a joint 392 is fixedly installed on the inner cylinder 31. The joint 392 is arranged inside the guide groove 391, and the guide groove 391 extends along the axial direction of the inner cylinder 31. The joint 392 is electrically connected to the optical fiber bundle light guide assembly.

[0057] In the embodiment of the present application, in order to enable the optical fiber bundle light guide assembly to emit light, a guide groove 391 is provided on the outer surface of the outer shell 3, and a connector 392 is fixedly installed on the outer surface of the inner tube 31 at one end of the guide groove 391, which is electrically connected to the optical fiber bundle light guide assembly through the connector 392, thereby enabling the optical fiber bundle light guide assembly to emit light.

[0058] As shown in FIG8 , a ceramic coating 38 is cured on the outer surface of the optical fiber bundle 37 of the optical fiber bundle light guide assembly.

[0059] In this embodiment of the present application, the outer surface of the high-density optical fiber bundle 37 of the optical fiber bundle light guide assembly is cured with a ceramic adhesive coating 38, thereby improving airtightness. Because the ceramic adhesive, with a thermal expansion coefficient close to that of the optical fiber, is pre-molded onto the optical fiber, the thermal expansion coefficients of the two are nearly matched, thereby reducing the compressive stress on the optical fiber during airtight packaging, thereby ensuring the optical properties of the optical fiber. The density of the optical fiber bundle 37 is relatively high, exceeding a predetermined density threshold.

[0060] How this application works:

[0061] With reference to Figures 1‑4 of the specification, when conducting a test, the optical fiber bundle light guide assembly is first installed on the mounting seat 2. When adjusting the direction, it is necessary to first slide the ring 13 downward along the slide groove 12, and the slider 14 will drive the inner rod 15 to move downward, so that the chuck 17 at the top of the inner rod 15 is disengaged from the slot 27 at the bottom end of the turntable 21. During the downward movement of the inner rod 15, the first return spring 16 at the bottom end of the inner rod 15 is squeezed, and then the first knob 25 or the second knob 26 under the mounting seat 2 is rotated according to the rotation direction required by the operator, thereby driving the first gear 23 and the second gear 24 inside to rotate. The first gear 23 and the second gear 24 are both meshed and connected with the gear ring 22, and the turntable is driven to rotate by the gear ring 22. The first gear 23 and the second gear 24 have different sizes and numbers of teeth, which drive the turntable 21 to rotate with different precision. The larger the gear size and the number of teeth, the smaller the turntable rotation precision, which is convenient for adjusting the direction rotation precision of the optical fiber bundle light guide assembly;

[0062] Referring to Figures 5‑7 of the specification, when adjusting the height of the optical fiber bundle light guide assembly, it is necessary to first push the pressure rods 341 on both sides of the knob 34 inward. The pressure rod 341 drives the limiting rod 343 at one end to move inward through the connecting plate, so that one end of the limiting rod 343 is disengaged from the limiting groove on the inner wall of the rotating groove 33, thereby releasing the limit on the knob 34. Then, the knob 34 is rotated, and the third gear 36 at one end is driven into the adjustment groove 32 through the connecting shaft 35. The third gear 36 is engaged with the tooth on one side of the inner wall of the adjustment groove 32. During the rotation of the third gear 36, the inner cylinder 31 will be driven to move to adjust the height of the optical fiber bundle light guide assembly.
