[0030] like Figures 1-6 As shown, this invention illustrates a fiber optic splice cassette for quick fiber optic splicing, comprising a cassette body, an upper cover 1, and a lower cover 2. The upper cover 1 is bolted to the lower cover 2. The cassette also includes a feed inlet 3, a fiber optic spool 4, a fixing seat 5, a fixing groove 7, a fixing bracket 8, and a positioning mechanism. Two feed inlets 3 are provided on each of the opposite side walls of the cassette body. The fiber optic spool 4 is fixedly disposed inside the lower cover 2. Fixing seats 5 are fixedly disposed on both sides of the inner bottom wall of the lower cover 2, corresponding to the fiber optic spool 4. Fixing grooves 6 are provided on the fixing seats 5 at positions corresponding to the feed inlets 3. Fixing grooves 7 are provided on both sides of the top side wall of the fixing seats 5, corresponding to the fixing grooves 6. A U-shaped fixing frame 8 is provided on one side of the fixed through groove 6. The two ends of the fixing frame 8 extend into the fixed groove 7 and are slidably connected to the side wall of the fixed groove 7. A positioning mechanism is set between the fixing frame 8 and the fixed groove 7 to position the fixing frame 8 and the side wall of the fixed groove 7. A sealing ring 22 is provided in the feed port 3, and the sealing ring 22 abuts against the side wall of the feed port 3. Specifically, after the optical cable is inserted into the fixed through groove 6, the fixing frame 8 and the fixing seat 5 can be installed and fixed by the positioning mechanism. Thus, the optical cable can be positioned and fixed by the cooperation of the clamping through groove 21 on the fixing frame 8 and the fixed through groove 6, thereby avoiding the optical cable from shifting position and affecting the splicing effect of the optical cable.

[0031] Reference Figures 2-5The positioning mechanism includes a first positioning groove 9, a second positioning groove 10, a positioning block 11, and a relative moving mechanism. The two opposite side walls of the fixed groove 7 are provided with the first positioning groove 9. The side wall of the fixed frame 8 is provided with the second positioning groove 10 on one side of the first positioning groove 9. The first positioning groove 9 and the second positioning groove 10 are aligned. The positioning block 11 is slidably disposed in the second positioning groove 10. The relative moving mechanism is disposed in the fixed frame 8 and is used to drive the two adjacent positioning blocks 11 to move relative to each other. A support spring 20 is fixedly disposed between the positioning block 11 and the bottom of the second positioning groove 10. The inner top wall of the fixed frame 8 is provided with an arc-shaped clamping through groove 21. Specifically, after the end of the fixed frame 8 is inserted into the fixed groove 7, the operation of the relative moving mechanism can drive the two positioning blocks 11 to move relative to each other, thereby driving the end of the positioning block 11 to extend into the first positioning groove 9. Then, the positioning and fixing between the fixed frame 8 and the fixed seat 5 are achieved by the cooperation of the positioning block 11 with the first positioning groove 9 and the second positioning groove 10 respectively.

[0032] Reference Figures 4-6 The relative movement mechanism includes a first cavity 12, an adjustment port, an adjustment column 14, and a rotation mechanism. The first cavity 12 is opened on one side of the second positioning groove 10. An adjustment plate 13 is rotatably arranged in the first cavity 12. Two arc-shaped adjustment through holes are symmetrically opened on the adjustment plate 13. An adjustment port is opened on the top side wall of the second positioning groove 10 and communicates with the first cavity 12. An adjustment column 14 is fixedly arranged on the top side wall of the positioning block 11. The top end of the adjustment column 14 extends through the adjustment port into the adjustment through hole. The rotation mechanism is set on the fixed frame 8 and is used to drive the adjustment plate 13 to rotate. The rotation of the adjustment plate 13 can drive the adjustment through hole to move around the adjustment plate 13. During the movement of the adjustment through hole, the adjustment column 14 and the positioning block 11 can be moved relative to each other by squeezing the adjustment through hole.

[0033] Reference Figures 4-6The rotating mechanism includes a second cavity, a first bevel gear 15, and a synchronous rotating mechanism. The second cavity is located on one side of the first cavity 12. The first bevel gear 15 is rotatably mounted on the inner bottom wall of the second cavity. A connecting rod 16 is fixedly mounted between the first bevel gear 15 and the adjusting plate 13. The synchronous rotating mechanism is mounted on the fixed frame 8 and is used to drive the two first bevel gears 15 to rotate synchronously. The synchronous rotating mechanism includes a second bevel gear 17, a drive rod 18, and a handwheel 19. The second bevel gear 17 is rotatably mounted on the side wall of the second cavity and meshes with the adjacent first bevel gear 15. The drive rod 18 is fixedly mounted between the two second bevel gears 17. The handwheel 19 is rotatably mounted on the fixed frame 8 and is fixedly connected to the drive rod 18. Specifically, when the operator rotates the handwheel 19, the rotation of the handwheel 19 can drive the drive rod 18 and the second bevel gear 17 to rotate. At the same time, the meshing of the second bevel gear 17 with the first bevel gear 15 drives the first bevel gear 15 and the adjusting plate 13 to rotate.

[0034] In this embodiment, during use, the operator opens the housing and places the optical cable into the fixed through slot 6 through the feed port 3. Then, the operator rotates the handwheel 19. The rotation of the handwheel 19 drives the drive rod 18 and the second bevel gear 17 to rotate. Simultaneously, the meshing of the second bevel gear 17 with the first bevel gear 15 drives the first bevel gear 15 and the adjusting disc 13 to rotate. The rotation of the adjusting disc 13 causes the adjusting through hole to move around the adjusting disc 13. During the movement of the adjusting through hole, the adjusting column 14 and the positioning block 11 can be adjusted by the pressure exerted on the adjusting through hole. The relative movement causes the positioning block 11 to retract into the second positioning groove 10. Then, the operator inserts the end of the fixing frame 8 into the fixing groove 7 and releases the handwheel 19. This allows the positioning block 11 to be pushed into the first positioning groove 9 by the support spring 20. Thus, the positioning and fixing of the fixing frame 8 and the fixing seat 5 can be achieved by the cooperation of the positioning block 11 with the first positioning groove 9 and the second positioning groove 10 respectively. At this time, the optical cable can be fixed by the cooperation of the clamping through groove 21 and the fixing through groove 6. Then, the optical cable can be spliced ​​by the fiber splicing tray 4.
