[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 -Appendix Figure 4 The present invention provides an optical fiber adapter, including an adapter housing 1, two connecting copper frames 2 inside the adapter housing 1, and a positioning plate 3 fixedly embedded inside the adapter housing 1, the positioning plate 3 being disposed between the two connecting copper frames 2.

[0028] The positioning plate 3 has a connecting mechanism inside, which is used to position and connect the optical fiber line;

[0029] The connecting mechanism includes a drive shaft 4, which is embedded inside the positioning plate 3 and the adapter housing 1. The drive shaft 4 is movably connected to the positioning plate 3 and the adapter housing 1 via rolling bearings.

[0030] The positioning plate 3 has a cavity inside, which is sleeved on the outside of the drive shaft 4. Two threaded rods 5 are embedded inside the cavity, and both threaded rods 5 are fixedly sleeved on the outside of the drive shaft 4.

[0031] In this embodiment, the user inserts the two optical fiber lines into both sides of the adapter housing 1, and the user turns the rotating handle 15 to rotate, so that the connection mechanism works to position and clamp the two optical fiber lines, and also to connect the optical fibers.

[0032] To achieve the purpose of fiber optic line connection, this device adopts the following technical solution: The connection mechanism also includes two sliding blocks 6, both of which are embedded inside the cavity. The outer sides of both sliding blocks 6 are square structures, and the sliding blocks 6 fit against the inner wall of the cavity. The two sliding blocks 6 are respectively sleeved on the outer sides of two threaded rods 5, and the threaded rods 5 are connected to the sliding blocks 6 by threads. Connecting rods 7 are fixedly connected to both sides of the two sliding blocks 6. Lifting grooves are opened on both sides of the positioning plate 3. The two connecting rods 7 pass through the two lifting grooves and extend to the outer side of the positioning plate 3. The outer ends of the multiple connecting rods 7 are fixedly connected to stop rods 8, and the multiple stop rods 8 are all cylindrical. The structure includes multiple stop bars 8 located inside the two connecting copper frames 2, positioning grooves 9 on both sides of the positioning plate 3, positioning clamps 10 embedded inside the two positioning grooves 9, multiple positioning clamps 10 fixedly connected to the outside of multiple connecting rods 7, anti-slip grooves 11 on the inside of multiple positioning clamps 10, multiple positioning blocks 12 fixedly embedded inside the adapter housing 1, multiple positioning blocks 12 located inside the two connecting copper frames 2, the top end of the drive shaft 4 extending to the top of the adapter housing 1, a square rod 13 fixedly connected to the top end of the drive shaft 4, a connecting frame 14 fixedly connected to the top of the square rod 13, and a rotating handle 15 fixedly connected to the top of the connecting frame 14.

[0033] Rotating handle 15 drives transmission shaft 4 to rotate, which in turn drives threaded rod 5 to rotate. The rotation of the two threaded rods 5 drives two sliding blocks 6 to move towards the center. The two threaded rods 5 in this device have opposite thread orientations. The movement of sliding blocks 6 drives multiple connecting rods 7 to move towards the center. The movement of multiple connecting rods 7 drives multiple positioning clamps 10 to move towards the center. The movement of multiple positioning clamps 10 positions and clamps the two optical fiber lines. At the same time, the two connecting rods 7 move down, driving multiple stop rods 8 to move towards the center, thereby squeezing the connecting copper frame 2, so that the two connecting copper frames 2 clamp and connect the two optical fiber lines, allowing the optical fiber to pass through.

[0034] In order to achieve the purpose of preventing loosening, the device adopts the following technical solution: a connecting ring 16 is sleeved on the outside of the square rod 13, and multiple fixing rods 17 are fixedly connected to the outside of the connecting ring 16. Each of the multiple fixing rods 17 is fixedly connected to a buckle 18 at the bottom. Multiple slots 19 are opened on the top of the adapter housing 1, and the multiple buckles 18 are respectively matched with the multiple slots 19.

[0035] After positioning is complete, the user pulls down the connecting ring 16, causing multiple fixing rods 17 and buckles 18 to move down. The multiple buckles 18 move down and embed into multiple slots 19 to prevent the drive shaft 4 from rotating and to prevent the fiber optic connection from becoming loose.

[0036] The usage process of this utility model is as follows: The user inserts two optical fiber lines into both sides of the adapter housing 1. The user turns the rotating handle 15 to make the connecting mechanism work to position and clamp the two optical fiber lines, and also to connect the optical fibers. The rotation of the rotating handle 15 drives the drive shaft 4 to rotate, and the drive shaft 4 drives the threaded rod 5 to rotate. The two threaded rods 5 rotate and drive the two sliding blocks 6 to move towards the middle. The two threaded rods 5 in this device have opposite thread orientations. The movement of the sliding blocks 6 drives multiple connecting rods 7 to move towards the middle. The movement of the multiple connecting rods 7 drives multiple positioning clamps 10 to move towards the middle. The movement of the multiple positioning clamps 10 positions and clamps the two optical fiber lines. At the same time, the two connecting rods 7 move down and drive multiple stop rods 8 to move towards the middle, thereby squeezing the connecting copper frame 2, so that the two connecting copper frames 2 clamp and connect the two optical fiber lines, so that the optical fibers can pass through. After the positioning is completed, the user pulls down the connecting ring 16, so that multiple fixing rods 17 and buckles 18 move down. The multiple buckles 18 move down and embed into multiple slots 19, preventing the drive shaft 4 from rotating and preventing the optical fiber connection from loosening.
