Description

Technical Field

[0001] The utility model relates to the field of optical cable distribution boxes, and particularly relates to an optical cable distribution box convenient for maintenance. Background Art

[0002] The optical cable distribution box is a key link in the communication network. It is responsible for the connection, distribution, and protection of optical cables. If the distribution box fails or its performance deteriorates, it will cause the interruption or attenuation of communication signals and affect the communication quality. Therefore, regular maintenance of the optical cable distribution box can ensure its normal operation and guarantee the stability and reliability of communication.

[0003] After retrieval, the patent with the Chinese patent publication number CN206757125U discloses an optical cable distribution box, which includes a box body; a plurality of drawer-type connection trays, and the plurality of drawer-type connection trays include a terminal connection tray and a splicing tray connected together. The plurality of drawer-type connection trays are stacked in parallel in the box body; an optical fiber branching box, which is arranged at a position close to the bottom surface inside the box body; a wire groove, which is arranged on the side of the plurality of drawer-type connection trays; a wire loop, which is arranged in the box body for winding the jump fiber; wherein, the terminal connection tray is used for the termination of optical fibers, and the splicing tray is used for the splicing of optical fibers.

[0004] The above patent has the following deficiencies: by setting a plurality of drawer-type connection trays, when connecting the branch optical fiber to the main optical fiber, the drawer-type connection tray can be pulled out of the box body for connection, which is convenient for users to connect the branch optical fiber to the main optical fiber. However, when the drawer-type connection tray is pulled out, the optical fiber connected to it will also be pulled out. When it is pushed back into the box body, the optical fiber cannot be effectively guided or wound up. Therefore, the redundant optical fiber will be squeezed and wound, and over time, it is easy to cause damage to the optical fiber, thereby reducing its performance and service life.

[0005] Therefore, the present new example proposes an optical cable distribution box convenient for maintenance. Summary of the Utility Model

[0030] The embodiments of the present utility model will be described in detail below with reference to the drawings. Embodiment 1

[0031] As Figures 1-3 shown, an optical cable cross-connect box facilitating maintenance includes a box body 1 and a box door 2 installed on one outer wall of the box body 1 through a hinge.

[0032] A plurality of groups of symmetrically arranged slide rail assemblies 3 are provided inside the box body 1, and the two slide rail assemblies 3 are connected by a bearing plate 4. A clamping assembly 5 for clamping and fixing the fiber optic splice tray A is provided on the top of the bearing plate 4, and an optical cable winding and unwinding assembly 6 is provided on the side of the bearing plate 4 away from the box door 2.

[0033] The cable winding and unwinding assembly 6 includes a limiting rod 7 and a slider 8. A connecting shaft is fixedly connected to the opposite sides of the two sliders 8. The limiting rod 7 is rotatably connected to the outer circumference of the connecting shaft. A second chute 9 is provided on the inner wall of the box body 1, and the slider 8 is slidably fitted to the inner wall of the second chute 9. A through hole for passing through the optical cable B is provided on the inner wall of the box body 1 away from the box door 2, and the limiting rod 7 is rollingly fitted to the outer wall of the optical cable B.

[0034] Fix the fiber optic splice tray A on the top of the bearing plate 4 through the clamping assembly 5. Insert the optical cable B into the box body 1 through the through hole, bypass the bottom of the limiting rod 7 and finally connect it to the fiber optic splice tray A. When the slider 8 drives the limiting rod 7 and the connecting shaft to gradually move upward along the inner wall of the second chute 9, at this time, pull the bearing plate 4 and the fiber optic splice tray A outwards, and the optical cable B is gradually straightened. Then, perform the maintenance work on the fiber optic splice tray A. After the maintenance is completed, push the bearing plate 4 and the fiber optic splice tray A inwards, and use the slider 8 to drive the connecting shaft and the limiting rod 7 to gradually move downwards, so that the optical cable B gradually bends under the guiding action of the limiting rod 7, thereby enabling the limiting rod 7 to play a role in limiting and guiding the optical cable B.

[0035] By setting the limiting rod 7, the slider 8 and the connecting shaft, the limiting rod 7 can limit and guide the optical cable B, so that the optical cable B can move outwards as the bearing plate 4 and the fiber optic splice tray A move outwards. When the bearing plate 4 and the fiber optic splice tray A are pushed in, it can be in a bent state under the guiding of the limiting rod 7, avoiding the situation that the optical cable B is damaged due to long-term extrusion and winding after being pushed in, thus ensuring network stability and data security.

[0036] As Figure 3 shown, a first spring 11 is buckled on the opposite sides of the slider 8 and the second chute 9. A rope winding wheel 12 is rotatably connected to the inner wall of the box body 1 above the second chute 9.

[0037] A connecting rope 10 is wound around the outer wall of the rope winding wheel 12. One end of the connecting rope 10 is fixedly connected to the connecting shaft, and the other end of the connecting rope 10 is connected to the slide rail assembly 3.

[0038] When pulling the bearing plate 4 outwards, the slide rail assembly 3 drives one end of the connecting rope 10 to move outwards, and the other end of the connecting rope 10 drives the slider 8 to slide along the inner wall of the second chute 9. Thus, when the fiber optic splice tray A moves outwards with the bearing plate 4, the limiting rod 7 and the connecting shaft can move upwards under the drive of the slider 8 and the connecting rope 10, and at this time, the first spring 11 is elastically deformed under force; when pushing the bearing plate 4 and the fiber optic splice tray A inwards, the first spring 11 uses its own elasticity to push the slider 8, the limiting rod 7 and the connecting shaft downwards, so that the optical cable B gradually forms a bent state under the limiting and guiding of the limiting rod 7.

[0039] By arranging the connecting rope 10 and the first spring 11, when the bearing plate 4 and the fiber optic cable tray A are pulled out, under the cooperation of the connecting rope 10, the rope winding wheel 12 and the connecting shaft, the limiting rod 7 gradually rises and releases the restriction on the optical cable B, and the optical cable B can be smoothly pulled out. When the bearing plate 4 and the fiber optic cable tray A are pushed in, the elastic action of the first spring 11 can make the limiting rod 7 gradually descend again to provide limit guidance for the optical cable B, thereby increasing the linkage of the device and improving the convenience of use of the device.

[0040] As Figure 4 shown, the slide rail assembly 3 includes two symmetrically arranged fixed plates 13 and a moving plate 16. The fixed plate 13 is fixedly connected to the inner wall of the box body 1, and a first chute 14 is provided on the inner wall of the fixed plate 13.

[0041] A roller 15 is rollingly engaged in the first chute 14. A rotating shaft is fixed to the inner wall of the roller 15, and one end of the rotating shaft is rotatably connected to the outer wall of the moving plate 16. The bearing plate 4 is fixedly connected to the opposite sides of the two moving plates 16 by bolts, and one end of the connecting rope 10 is fixedly connected to the top of the moving plate 16.

[0042] The moving plate 16 can horizontally move along the first chute 14 through the roller 15 and the rotating shaft, so that the bearing plate 4 and the fiber optic cable tray A can be pulled out or pushed in, and each bearing plate 4 and fiber optic cable tray A can be individually pulled out, which is convenient for overhauling the device.

[0043] In this embodiment: when the device is in use, the fiber optic cable tray A is fixed on the top of the bearing plate 4 through the clamping assembly 5. The optical cable B is inserted into the box body 1 through the through hole, then bypasses the bottom of the limiting rod 7 and is finally connected to the fiber optic cable tray A. When overhauling is required, a bearing plate 4 can be individually pulled out, and the fiber optic cable tray A placed on the top of the bearing plate 4 is also pulled out. At the same time, one end of the connecting rope 10 moves outward under the drive of the moving plate 16, and the other end of the connecting rope 10 drives the slider 8, the connecting shaft and the limiting rod 7 to move upward. The limiting rod 7 gradually releases the restriction on the optical cable B, and the first spring 11 is elastically deformed under force. At this time, the end of the optical cable B connected to the fiber optic cable tray A also gradually moves outward, and then the fiber optic cable tray A and the optical cable B can be overhauled. After the overhaul is completed, the moving plate 16 and the bearing plate 4 are pushed inward, so that the fiber optic cable tray A moves inward accordingly. At the same time, the first spring 11 uses its own elastic deformation to push the slider 8, the connecting shaft and the limiting rod 7 to move downward, and the limiting rod 7 resumes the limit guidance for the optical cable B, so that the optical cable B gradually forms a bent state. Embodiment 2

[0044] A fiber optic cable cross-connect box convenient for overhauling. In this embodiment, the following improvements are made on the basis of Embodiment 1. As Figure 5 shown:

[0045] The clamping assembly 5 includes two symmetrically arranged clamping plates 19. The clamping plates 19 are slidably fitted to the top of the bearing plate 4. A plurality of second springs 17 are fixedly connected to the opposite sides of the two moving plates 16. The telescopic ends of the second springs 17 are fixedly connected to the opposite sides of the clamping plates 19. Anti-slip pads 20 are fixed to the opposite sides of the two clamping plates 19.

[0046] An expansion rod 18 is sleeved on the outer wall of the second spring 17. The two ends of the expansion rod 18 are respectively buckled to the outer walls of the moving plate 16 and the clamping plate 19.

[0047] In this embodiment: Push the two clamping plates 19 and the anti-slip pads 20 to both sides, then place the fiber optic splice tray A on the top of the bearing plate 4 and release the clamping plates 19 and the anti-slip pads 20. Under the cooperation of the second spring 17 and the expansion rod 18, the clamping plates 19 and the anti-slip pads 20 slide relatively, so that the anti-slip pads 20 are attached to both sides of the fiber optic splice tray A, thereby realizing the fixation of the fiber optic splice tray A.

[0048] By setting the clamping plates 19 and the anti-slip pads 20 in this device, after pushing the clamping plates 19 and the anti-slip pads 20 to both sides, the distance between the two anti-slip pads 20 is increased so that the fiber optic splice tray A can be placed between the two anti-slip pads 20. After releasing the clamping plates 19 and the anti-slip pads 20, the second spring 17 and the expansion rod 18 can push the two clamping plates 19 and the anti-slip pads 20 to slide relatively. When the anti-slip pads 20 are attached to both sides of the fiber optic splice tray A, the clamping and fixation of the fiber optic splice tray A are realized, thereby improving its stability.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
