[0002] Optical transmission is a technology that transmits optical signals between a sender and a receiver. Optical transmission equipment is a device that converts various signals into optical signals for transmission over optical fibers. Therefore, modern optical transmission equipment typically uses optical fibers, and existing optical transmission devices usually connect signal lines directly to the equipment during use. With the increasing prevalence of fiber optic networks, the maintenance and fault repair of fiber optic lines have become increasingly important. When a fiber optic line breaks or malfunctions and requires emergency repair, it is necessary to protect the reconnected fiber optic cable.

[0003] As shown in application number CN201210490515.5, the optical fiber protection device includes a first body and a second body that can be snapped together to form an optical fiber accommodating space for accommodating the optical fiber splice when snapped together, and remain connected as one body when not snapped together. The first body and the second body extend to form a first connecting portion and a second connecting portion, respectively. The first connecting portion and the second connecting portion are movably connected or foldably connected. The first body and the second body form a main body structure when snapped together. The optical fiber protection device also includes a nut, which is threadedly connected to the main body structure.

[0025] Example 1, combined with Figure 1 Explanation:

[0026] An optical transmission protection device includes a protective shell 1, a fixing plate 2, a first sliding plate 3, a second sliding plate 4, a rotating ring 5, and a rotating post 6. Two sets of protective shells 1 are provided, and the two sets of protective shells 1 are fitted onto an optical fiber 7 and are rotatably mounted. Two sets of fixing plates 2 are provided, and the two sets of fixing plates 2 are fixedly mounted onto the protective shells 1. The first sliding plate 3 and the second sliding plate 4 are respectively slidably mounted onto the two sets of protective shells 1. The rotating post 6 is fixedly mounted onto the protective shells 1, and the rotating ring 5 is fitted onto the rotating post 6.

[0027] With this setup, the optical fiber 7 is wrapped and protected by the protective shell 1 and the fixing plate 2. The first sliding plate 3 and the second sliding plate 4 are connected by sliding to connect the two sets of protective shells 1. The first vertical plate 32 and the second vertical plate 42 are set in the appropriate position. The first sliding plate 3 and the second sliding plate 4 are fixed by twisting the fixing ring groove 51 on the ring 5 to cooperate with the first vertical plate 32 and the second vertical plate 42.

[0028] Example 2, based on Example 1, combined with... Figure 2 Explanation:

[0029] The protective shell 1 includes a rotating connecting seat 11, a fixing head 12, and a housing 14. The rotating connecting seat 11 and the fixing head 12 are symmetrically arranged on both sides of the housing 14. The two sets of protective shells 1 are rotatably connected by the rotating connecting seat 11. The fixing head 12 has a through sliding groove 13. One end of the fixing plate 2 has a fixing groove 21, and the other end of the fixing plate 2 has a sliding groove 22. The fixing groove 21 of the fixing plate 2 extends out of the protective shell 1 and abuts against the optical fiber 7. A first sliding plate 3 or a second sliding plate 4 is slidably arranged in the sliding groove 22.

[0030] With this configuration, the optical fiber 7 is protected by two sets of rotating protective shells 1. The installation process is simplified by rotating and opening. The fixing head 12 on the shell 14 abuts against the optical fiber 7. The fixing groove 21 on the fixing head 12 improves the clamping effect on the optical fiber 7. The first sliding plate 3 or the second sliding plate 4 is slidably set on the protective shell 1 by the sliding groove 22 on the fixing head 12.

[0031] Example 3, based on Example 2, combined with Figure 4 Explanation:

[0032] A first vertical plate 32 is fixedly mounted on the first sliding plate 3, and a first positioning groove 31 is formed on the first sliding plate 3. A second vertical plate 42 is fixedly mounted on the second sliding plate 4, and a second positioning plate 41 is formed on the second sliding plate 4. The second positioning plate 41 is slidably mounted in the through sliding groove 13. The rotating post 6 is fixedly mounted on the fixing head 12 of a set of protective shells 1. The rotating post 6 includes a threaded part 61, a sliding part 62, and a limiting part 63. The threaded part 61 is fixedly mounted on the fixing head 12 and has threads. The sliding part 62 is fixedly mounted on the threaded part 61, and the limiting part 63 is fixedly mounted on the sliding part 62. A fixing screw 52 is provided inside the rotating ring 5. A sliding hole 53 is formed on the rotating ring 5. The rotating ring 5 is slidably mounted on the sliding part 62 through the sliding hole 53. The limiting part 63 restricts the movement of the rotating ring 5. A fixing ring groove 51 is formed on the rotating ring 5.

[0033] With this configuration, the first sliding plate 3 and the second sliding plate 4 are slidably mounted on the protective shell 1. After sliding, the first positioning groove 31 on the first sliding plate 3 and the second positioning plate 41 on the second sliding plate 4, in conjunction with the fixing head 12 on the protective shell 1, are positioned. The curvature of the first sliding plate 3 and the second sliding plate 4 connects the two sets of protective shells 1. After the first sliding plate 3 and the second sliding plate 4 slide to the fixed position, the first vertical plate 32 and the second vertical plate 42 are in the fixed position. At this time, the movement is achieved by tightening the screwing ring 5, causing the screwing ring 5 to pass through the fixing ring groove 51 and engage with the first vertical plate 3. 2. The first vertical plate 32 and the second vertical plate 42 are fitted together and housed in the fixing ring groove 51, thereby fixing the first sliding plate 3 and the second sliding plate 4. When the turning ring 5 abuts against the limiting part 63, the height of the first vertical plate 32 and the second vertical plate 42 is lower than that of the turning ring 5, ensuring that the first sliding plate 3 and the second sliding plate 4 can move. The depth of the fixing ring groove 51 is greater than the height of the first vertical plate 32 and the second vertical plate 42. The threaded part 61 is fitted with the fixing screw 52. The height of the sliding part 62 is greater than the height of the first vertical plate 32 and the second vertical plate 42.

[0034] The working principle of this utility model is as follows: The protective shell 1 and the fixing plate 2 are rotatably connected by a rotating shaft. The fixing groove 21 on the fixing plate 2 clamps the optical fiber 7, and the device is fixedly set on the optical fiber 7. The first sliding plate 3 and the second sliding plate 4 slide on the protective shell 1. The curvature of the first sliding plate 3 and the second sliding plate 4 is combined with the curvature of the protective shell 1 to reinforce it. When the first sliding plate 3 and the second sliding plate 4 slide to the fixed position, the turning ring 5 is turned. The movement of the turning ring 5 on the rotating post 6 makes the fixing ring groove 51 cooperate with the first vertical plate 32 and the second vertical plate 42, and the first sliding plate 3 and the second sliding plate 4 are fixed. This utility model protects the optical fiber 7 through the protective shell 1 and the fixing plate 2, and completes the merging and fixing through the cooperation of the first sliding plate 3, the second sliding plate 4 and the turning ring 5 to prevent it from falling off.
