Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0031] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In the fixed optical fiber distribution box in the first embodiment of the present utility model, it includes: a distribution box 1, a pulling plate 2, and a mounting component 3. The distribution box 1 is used to connect optical fibers; a receiving groove 31 is provided on the mounting component 3, and the receiving groove 31 penetrates along the first direction to the front end 38 and the rear end 39 of the mounting component 3. The distribution box 1 is slidably arranged in the receiving groove 31. The pulling plate 2 is slidably arranged in the receiving groove 31 along the first direction and extends out from the front end 38 and the rear end 39 of the receiving groove 31. The pulling plate 2 is connected to the distribution box 1 and can be withdrawn from the front end 38 or the rear end 39 of the receiving groove 31 following the sliding of the pulling plate 2. After the distribution box 1 is arranged in the receiving groove 31, since the entire optical fiber distribution box is arranged relatively tightly, it is difficult to take out the distribution box 1 from the receiving groove 31. When the distribution box 1 is arranged in the receiving groove 31, the pulling plate 2 is connected to the distribution box 1 on one side of the distribution box 1. When the pulling plate 2 is pulled to move relative to the receiving groove 31 along the first direction, the distribution box 1 follows the pulling plate 2 and is taken out of the receiving groove 31.

[0032] According to some embodiments of the present utility model, a baffle 34 is provided in the receiving groove 31. The receiving groove 31 includes a first sliding groove 32 and a second sliding groove 33. The baffle 34 has a notch 37. The first sliding groove 32 and the second sliding groove 33 are communicated through the notch 37. The wiring box 1 is slidably connected to the first sliding groove 32, and the pulling plate 2 is slidably connected to the second sliding groove 33; a connecting component 4 is provided on one side of the pulling plate 2 close to the wiring box 1. The connecting component 4 is connected to the wiring box 1 through the notch 37. The connecting component 4 connects the baffle 34 and the wiring box 1 in the notch 37. At this time, under the action of the connecting component 4, the wiring box 1 can move following the pulling plate 2. That is, when the connecting component 4 is in the notch 37, the pulling plate 2 and the wiring box 1 are fixedly connected. Further, when the pulling plate 2 is pulled to move in the first direction so that the connecting component 4 moves to one end of the notch 37, the connecting component 4 is squeezed against the baffle 34, so that the connection of the connecting component 4 is released, that is, the pulling plate 2 and the wiring box 1 are disconnected. At this time, a part of the wiring box 1 has been pulled out of the receiving groove 31 by the pulling plate 2, and at this time, the fixed connection between the pulling plate 2 and the wiring box is also disengaged. In this way, the wiring box 1 can be pulled out of the receiving groove 31, and the pulling plate 2 does not need to be removed from the second sliding groove 33.

[0033] According to some embodiments of the present utility model, the connecting component 4 includes a first convex block 41 and a second convex block 42 arranged at intervals in the first direction. The connecting component 4 is configured to have a first state and a second state. When the connecting component 4 is in the first state, both the first convex block 41 and the second convex block 42 are connected to the wiring box 1. When the connecting component 4 is in the second state, the pulling plate 2 is driven to drive the wiring box 1 to slide, and the first convex block 41 moves in a direction away from the second convex block 42, so that the first convex block 41 is separated from the wiring box 1 and exits from the second sliding groove 33. Specifically, when in the first state, both the first convex block 41 and the second convex block 42 are connected to the wiring box 1, making the connection between the pulling plate 2 and the wiring more stable. When the wiring box 1 is pulled along the direction where the first convex block 41 faces away from the second convex block 42 by the pulling plate 2, when the first convex block 41 slides out of the notch 37, the connection between the first convex block 41 and the wiring box 1 is separated, so that the pulling plate 2 can pull the wiring box 1 out farther. Further, after the first convex block 41 is separated from the wiring box 1, the wiring box 1 can be pulled so that the connection between the wiring box 1 and the second convex block 42 is separated. Or continue to pull the pulling plate 2. When the second convex block 42 is pulled out of the notch 37, the second convex block 42 is also separated from the wiring box 1, so that the connection between the pulling plate 2 and the wiring box 1 is separated.

[0034] According to some embodiments of the present utility model, a first abutting surface 43 is provided on the first bump 41, and a second abutting surface 44 is provided on the second bump 42; the first abutting surface 43 faces the second bump 42, and the second abutting surface 44 faces the first bump 41; when the connecting assembly 4 is in the first state, both the first abutting surface 43 and the second abutting surface 44 are in contact with the wiring box 1; when the connecting assembly 4 is in the second state, the first abutting surface 43 is separated from the wiring box 1. Specifically, the first bump 41 is provided on one side of the pulling plate 2 close to the front end 38 of the receiving groove 31, and the second bump 42 is provided on one side of the pulling plate 2 close to the rear end 39 of the receiving groove 31. At this time, the first abutting surface 43 faces the rear end 39 and the second abutting surface 44 faces the front end 38. In the first state, the first abutting surface 43 and the second abutting surface 44 abut against the wiring box 1 in two directions, that is, the first abutting surface 43 and the second abutting surface 44 clamp and fix the wiring box 1. At this time, the pulling plate 2 and the wiring box 1 are completely fixed, and when the pulling plate 2 is pulled to move in the first direction, the connecting assembly 4 is in the second state. For example, when the pulling plate 2 is pulled to move forward toward the front end 38, at this time, the first bump 41 is separated from the wiring box 1, so that the contact between the first abutting surface 43 and the wiring box 1 is lost. However, at this time, there is still a contact relationship between the second abutting surface 44 and the wiring box 1, that is, pulling the pulling plate 2 can still drive the wiring box 1 to move. When the wiring box 1 is pulled to continue moving forward toward the front end 38, the wiring box 1 will be separated from the second abutting surface 44, that is, the wiring box 1 and the pulling plate 2 are separated. The wiring box 1 can be taken out of the receiving groove 31.

[0035] According to some embodiments of the present utility model, the baffle 34 includes a first part 35 and a second part 36 arranged at intervals in the first direction. The first part 35 is arranged at the front end 38 of the receiving groove 31, and the second part 36 is arranged at the rear end 39 of the receiving groove 31. A first inclined surface 45 is provided on one side of the first bump 41 close to the first part 35, and a second inclined surface 46 is provided on one side of the second bump 42 close to the second part 36. When the connecting component 4 switches from the first state to the second state, the first inclined surface 45 abuts against the first part 35 to separate the first abutting surface 43 from the wiring box 1, or the second inclined surface 46 abuts against the second part 36 to separate the second abutting surface 44 from the wiring box 1. After the baffle 34 is arranged as the first part 35 and the second part 36 arranged at intervals in the first direction, a gap 37 is formed between the first part 35 and the second part 36. Specifically, the first part 35 is arranged at the front end 38 of the receiving groove 31, the second part 36 is arranged at the rear end 39 of the receiving groove 31, and the first bump 41 and the second bump 42 are arranged between the first part 35 and the second part 36, that is, in the gap 37. When the pull plate 2 is pulled and moved forward towards the front end 38, the first inclined surface 45 on the first bump 41 presses against the first part 35, causing elastic deformation of the pull plate 2 or the first bump 41, so that the first abutting surface 43 and the wiring box 1 are misaligned and separated. And the first bump 41 can pass through the first part 35. Further, after the wiring box 1 in the receiving groove 31 is taken out, the pull plate 2 is continuously pulled. When the first bump 41 moves out of the first part 35, the first part 35 can still abut against the second abutting surface 44 on the second bump 42 to prevent the pull plate 2 from moving out of the second sliding groove 33.

[0036] According to some embodiments of the present utility model, a first groove 11 and a second groove 12 are provided on the wiring box 1. When the connecting assembly 4 is in the first state, the first bump 41 is located in the first groove 11, and the second bump 42 is located in the second groove 12. When the connecting assembly 4 is in the second state, the first bump 41 is located in the first groove 11 and the second bump 42 is disengaged from the second groove 12, or the first bump 41 is disengaged from the first groove 11 and the second bump 42 is located in the second groove 12. A third inclined surface 13 is provided in the first groove 11. When the first bump 41 is located in the first groove 11, the first inclined surface 45 fits with the third inclined surface 13. A fourth inclined surface 14 is provided in the second groove 12. When the second bump 42 is located in the second groove 12, the second inclined surface 46 fits with the fourth inclined surface 14. In order to make the connection between the pull plate 2 and the wiring box 1 closer, the first groove 11 and the second groove 12 are provided on the wiring box 1, which not only enables the inner wall of the first groove 11 to cooperate with the first abutting surface 43 and the inner wall of the second groove 12 to cooperate with the second abutting surface 44, but also provides a third inclined surface 13 in the first groove 11 to cooperate with the first inclined surface 45, and a fourth inclined surface 14 in the second groove 12 to cooperate with the second inclined surface 46. Taking the first groove 11 as an example, when the pull plate 2 is pulled to move towards the front end 38, under the action of the first part 35, the first bump 41 moves out of the first groove 11, so that the cooperation between the first abutting surface 43 and the wiring box 1 is lost. Then, when the wiring box 1 is pulled to move, the cooperation between the second inclined surface 46 and the fourth inclined surface 14 makes it easier for the second bump 42 to move out of the second groove 12.

[0037] According to some embodiments of the present utility model, a first positioning block 21 and a second positioning block 22 are provided on the side of the pull plate 2 close to the wiring box 1. When the connecting assembly 4 is in the first state, the first positioning block 21 abuts against the side of the first part 35 close to the second part 36, and the second positioning block 22 abuts against the side of the second part 36 close to the first part 35. Specifically, the first positioning block 21 and the second positioning block 22 are elastic protrusions. When the pulling force is greater than a certain degree, the first positioning block 21 and the second positioning block 22 can pass through the second sliding groove 33, so that the wiring box 1 can be more stably installed in the receiving groove 31 in the first state, avoiding the wiring box 1 from shaking in the receiving groove 31, and at the same time making the wiring box 1 more accurately located at the installation position.

[0038] According to some embodiments of the utility model, a limiting portion 23 is provided at the first end of the pull plate 2 extending from the receiving groove 31, and the projection formed by the second slide groove 33 along the first direction is located within the projection formed by the limiting portion 23 along the first direction. By providing the limiting portion 23 at the position where the receiving groove 31 is extended on the pull plate 2, when the pull plate 2 is pulled, it is used to block one end of the pull plate 2 from passing through the second slide groove 33, thereby preventing the pull plate 2 from being restricted by the second slide groove 33. Furthermore, a hand-held portion 24 is provided at the second end of the pull plate 2 extending from the receiving groove 31, so that the user can clamp the pull plate 2.

[0039] According to some embodiments of the utility model, a reset assembly 5 is provided on the side of the pull plate 2 facing away from the wiring box 1. The reset assembly 5 includes a fixed end 53 and a movable end 54. The fixed end 53 is provided on the wall surface of the receiving groove 31, and the movable end 54 is provided on the pull plate 2. The reset assembly 5 is used to provide a force for the pull plate 2 to retreat into the receiving groove 31. Specifically, two springs 51 extending and retracting along the first direction and a reset block 52 are provided. One of the springs 51 is provided on the side of the reset block 52 close to the front end 38, one end is connected to the reset block 52, and the other end is connected to the groove wall of the receiving groove 31; the other spring 51 is provided on the side of the reset block 52 close to the rear end 39, one end is connected to the reset block 52, and the other end is connected to the groove wall of the receiving groove 31. Thus, the reset block 52 automatically stays at a fixed position when not affected by external force, that is, after the pull plate is pulled out and the pull plate is released, the pull plate can automatically reset. At this time, the reset block 52 is the movable end 54 of the reset assembly 5 , and the reset block 52 is fixedly connected to the pull plate 2 , so that the pull plate 2 automatically stays at a fixed position when not affected by external force.

[0040] According to some embodiments of the utility model, the installation assembly 3 is provided with a plurality of accommodating grooves 31 along the second direction, and the first direction is perpendicular to the second direction. Further, a housing 6 is included, and a plurality of installation assemblies 3 are provided on the housing 6 along the third direction, and the second direction is perpendicular to the first direction and perpendicular to the vertical direction. Thus, the arrangement of the wiring box 1 is more neat and compact.
