Description

Technical Field

[0001] This invention relates to the field of optical fiber channel technology, specifically an optical fiber channel for communication cabling. Background Technology

[0002] With the increasing cabling density in communication equipment rooms and data centers, fiber optic cable trays have become an important device for fiber optic cabling management. Currently, widely used fiber optic cable trays mostly employ a multi-layered arrangement of perforated management boards to store optical fibers in layers. To ensure the relative stability of the multi-layered management boards, bolts, clips, and other fixing structures are usually needed to combine and fix the management boards, resulting in a relatively complex overall structure.

[0003] During fiber optic cable deployment, due to the layered and fixed combing plates, the optical fibers cannot be directly placed into the bottom of the channel from top to bottom. They can only be placed and fixed layer by layer through the wire holes of the combing plates. The operation is cumbersome and time-consuming, making it impossible to place the optical fibers quickly. At the same time, during subsequent expansion, due to the structural limitations of the multi-layered fixed combing plates, the addition of new optical fibers still requires disassembly and assembly and threading layer by layer, making it difficult to complete the cabling operation quickly. This significantly reduces the efficiency of fiber optic cable deployment and fails to meet the needs of rapid cabling.

[0004] To address the problems mentioned above, those skilled in the art have proposed an optical fiber duct for communication cabling. Summary of the Invention

[0005] The purpose of this invention is to provide an optical fiber channel for communication cabling to solve the problems mentioned in the background art.

The combing rack has several longitudinally spaced fiber optic slots. Several spaced movable slots are formed on both sides of the inner wall of the fiber optic cable channel. The movable slots are V-shaped, and two symmetrically distributed mounting seats are installed in the middle of each movable slot. Each mounting seat is rotatably connected to a rotating rod, and a rotating plate is mounted on the rotating rod. The rotating plate is connected to an extension plate via an elastic element.

A sliding column is slidably arranged in the vertical guide slot and the oblique guide slot. A sliding rod is rotatably connected to the sliding column. A synchronization plate is installed at the bottom end of the sliding rod.

[0014] As a preferred embodiment of the present invention, the driving assembly includes an adjustment cavity formed on the top of the combing frame, an adjustment block slidably disposed in the adjustment cavity, a control rod fixedly connected to the synchronization plate on the adjustment block, and a screw threadedly connected to the adjustment block rotatably disposed in the adjustment cavity, the top end of the screw passing through the combing frame and connected to the rotating dial.

[0015] As a preferred embodiment of the present invention, the positioning component includes mounting grooves formed on both sides of the middle part of the adjustment cavity, mounting blocks are slidably disposed in the mounting grooves, locking balls are embedded in the mounting blocks, locking grooves that cooperate with the locking balls are provided on both sides of the adjustment blocks, and a second spring connected to the mounting block is disposed in the mounting groove.

[0016] As a preferred embodiment of the present invention, a fixing seat is installed inside the optical fiber channel, and the fixing seat is detachably connected to the combing frame.

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] Please see Figures 1-11 A fiber optic cable channel for communication cabling includes a fiber optic cable channel 1 and a combing rack 2 built into the fiber optic cable channel 1. The combing rack 2 has several longitudinally spaced fiber optic slots 3. Several spaced movable slots 4 are formed on both sides of the inner wall of the fiber optic slots 3. The movable slots 4 are V-shaped, and two symmetrically distributed mounting seats 5 are installed in the middle of each movable slot 4. A rotating rod 6 is rotatably connected to each mounting seat 5, and a rotating plate 7 is mounted on the rotating rod 6. The rotating plate 7 is connected to an extension plate 10 via an elastic element. The rotating plate 7, in conjunction with the extension plate 10, can support and limit the fiber optic cable. Symmetrically distributed limiting slots 14 are formed on both sides of the movable slots 4. Limiting plates 15 are slidably disposed within the limiting slots 14. The limiting plates 15 extending out of the limiting slots 14 limit the upper and lower sides of the rotating plate 7 when it is in a horizontal state. The cable channel also includes:

[0032] Limit control component 34 is installed inside the combing rack 2 and connected to the limit plate 15. It is used to control the extension and retraction state of the two limit plates 15 in the same movable groove 4. Under normal conditions, the two limit plates 15 in the same movable groove 4 are in the extended state to limit the rotation of the rotating plate 7. When placing optical fiber, the top limit plate 15 is in the extended state. When taking out optical fiber, the bottom limit plate 15 is in the extended state.

[0033] A drive component 35 is disposed inside the combing rack 2 and connected to the limit control component 34, and is used to control the limit control component 34.

[0034] Positioning component 36, which is disposed inside the combing rack 2 and connected to the drive component 35, is used to position the drive component 35 at its initial position.

[0035] In use, the combing rack 2 is fixed in the fiber optic channel 1, and the limit control component 34 is driven by the drive component 35, so that the limit plates 15 at the bottom of all the movable slots 4 enter the limit slots 14, and the rotating plate 7 can rotate downwards, thereby pressing the optical fiber from the top of the fiber optic channel 3, passing over several rotating plates 7 and extension plates 10 to move the optical fiber to the corresponding separation area. With the cooperation of the rotating plates 7 and extension plates 10, the placed optical fiber can be separated and limited. Furthermore, the limit control component 34 extends both limit plates 15 in the movable slots 4 out of the limit slots 14, so that the limit plates 15 can limit the rotating plate 7 up and down, thereby preventing the rotating plate 7 and extension plate 10 from rotating arbitrarily and affecting the separation and limiting effect of the optical fiber. When it is necessary to remove the optical fiber, the limit control component 34 drives the limit plates 15 at the top of all the movable slots 4 into the limit slots 14, and the rotating plate 7 can rotate upwards, thereby facilitating the removal of the optical fiber.

[0036] In one instance of this embodiment, please refer to Figure 5 and Figure 8 The mounting base 5 has an inner cavity 12, and a torsion spring 13 connected to the rotating rod 6 is provided in the inner cavity 12.

[0037] The torsion spring 13 provides torque to the rotating rod 6, causing the rotating plate 7 to be subjected to an upward elastic force. When placing the optical fiber, the limiting plate 15 at the top of the movable groove 4 is in the state of extending out of the limiting groove 14. Under the action of the torsion spring 13, the rotating plate 7 will abut against the bottom surface of the limiting plate 15. At this time, the rotating plate 7 and the extension plate 10 are in a horizontal state, so that the optical fiber can be placed on the support plane formed by the rotating plate 7 and the extension plate 10. The torsion spring 13 can keep the rotating plate 7 and the extension plate 10 in a horizontal state, preventing the rotating plate 7 and the extension plate 10 from rotating downward due to the weight of the optical fiber.

[0038] In one instance of this embodiment, please refer to Figure 4 and Figure 5 The elastic element includes a sliding cavity 8 formed in the rotating plate 7, a slider 9 slidably disposed in the sliding cavity 8, the slider 9 being fixedly connected to the expansion plate 10, and a first spring 11 connected to the slider 9 disposed in the sliding cavity 8.

[0039] The first spring 11 is in a compressed state, which provides an elastic pushing force to the slider 9. The slider 9 is located at the end of the slide cavity 8 away from the rotating rod 6, so that the slider 9 abuts against the end of the slide cavity 8 away from the rotating rod 6. In this state, the extension plate 10 is in an extended state.

[0040] When placing the optical fiber, the optical fiber is pressed down from the top of the optical fiber slot 3 until it moves to the corresponding partition area of ​​the optical fiber slot 3. During the downward pressing of the optical fiber, it will push the rotating plate 7 and the extension plate 10, causing them to rotate downward until the optical fiber passes over the original support plane of the rotating plate 7 and the extension plate 10. Then, under the action of the torsion spring 13, the rotating plate 7 will return to its original position. In order to avoid the inserted optical fiber from affecting the smooth return of the rotating plate 7, the extension plate 10 is squeezed into the sliding cavity 8 by the squeezing of the optical fiber sheath, thus facilitating the rotation of the rotating plate 7. After the rotating plate 7 passes the optical fiber, under the elastic force of the first spring 11, the slider 9 will return to its original position along the sliding cavity 8, and at the same time push the extension plate 10 out of the sliding cavity 8 to return to its original position.

[0041] In one instance of this embodiment, please refer to Figure 3 , Figures 6-8 The limiting control component 34 includes several sets of drive slots 17 formed in the combing frame 2 and corresponding to the movable slot 4. Each set of drive slots 17 has two slots, which correspond to two limiting plates 15 in the movable slot 4 respectively. A drive block 16 connected to the limiting plate 15 is slidably arranged in the drive slot 17. The drive block 16 is provided with an oblique guide slot 18 and an oblique guide slot 19 connected at the end. The oblique guide slots 18 and oblique guide slots 19 on the two drive blocks 16 corresponding to the movable slot 4 are symmetrically distributed. A sliding column 20 is slidably arranged in the oblique guide slots 18 and oblique guide slots 19. The sliding column 20 is rotatably connected to a sliding rod 21. A synchronization plate 22 is installed at the bottom end of the sliding rod 21.

[0042] In the initial state, both limiting plates 15 in the same movable slot 4 are in the extended state. At this time, the rotating plate 7 is in the limiting state, which can limit the inserted optical fiber. In this state, the sliding column 20 in the drive block 16 connected to the upper limiting plate 15 of the movable slot 4 will be located at the top of the vertical guide slot 18, while the sliding column 20 in the drive block 16 connected to the lower limiting plate 15 of the movable slot 4 will be located at the bottom of the vertical guide slot 18. The upper and lower sliding columns 20 are both located at the connection between the vertical guide slot 18 and the oblique guide slot 19.

[0043] During fiber placement, the synchronous plate 22 is driven downward by the drive assembly 35, which in turn drives the slide bar 21 downward. The slide bar 21 drives all the slide columns 20 to move downward synchronously. During this process, the slide column 20 of the drive block 16 corresponding to the upper limit plate 15 of the movable slot 4 slides down along the vertical guide groove 18 until it reaches the bottom of the vertical guide groove 18, keeping the drive block 16 in its original position. Meanwhile, the slide column 20 of the drive block 16 corresponding to the lower limit plate 15 of the movable slot 4 enters the oblique guide groove 19 from the bottom of the vertical guide groove 18 until it reaches the bottom of the oblique guide groove 19. During this process, the lower drive block 16 is pushed and slides along the lower drive groove 17, causing the lower limit plate 15 of the movable slot 4 to enter the limit groove 14. At this time, the lower part of the rotating plate 7 is no longer restricted, and the rotating plate 7 can rotate downward, allowing the fiber to be placed.

[0044] When the optical fiber is removed, the action is completely opposite to that when the optical fiber is placed. The driving block 16 corresponding to the lower limiting plate 15 in the movable groove 4 remains in its original position, while the driving block 16 corresponding to the upper limiting plate 15 slides along the driving groove 17, so that the upper limiting plate 15 enters the limiting groove 14, allowing the rotating plate 7 to rotate upward, making it convenient to remove the optical fiber.

[0045] In one instance of this embodiment, please refer to Figures 7-10 The drive assembly 35 includes an adjustment cavity 25 opened on the top of the combing frame 2. An adjustment block 24 is slidably arranged in the adjustment cavity 25. A control rod 23 connected to the synchronization plate 22 is fixedly connected to the adjustment block 24. A screw 26 threadedly connected to the adjustment block 24 is rotatably arranged in the adjustment cavity 25. The top end of the screw 26 passes through the combing frame 2 and is connected to the rotating dial 27.

[0046] In the initial state, the adjusting block 24 is located in the middle of the adjusting cavity 25, and the initial position of the adjusting block 24 is positioned by the positioning component 36. In this state, both limiting plates 15 in the movable groove 4 are in the state of extending out of the limiting groove 14. When the rotating lever 27 is rotated, the screw 26 can be driven to rotate, thereby driving the adjusting block 24 to slide up and down in the adjusting cavity 25. When the adjusting block 24 slides down, the lower limiting plate 15 in the movable groove 4 will enter the limiting groove 14, and the rotating plate 7 can rotate down. When the adjusting block 24 slides up, the upper limiting plate 15 in the movable groove 4 will enter the limiting groove 14, and the rotating plate 7 can rotate up.

[0047] In one instance of this embodiment, please refer to Figure 9The positioning component 36 includes mounting grooves 31 on both sides of the middle part of the adjustment cavity 25. A mounting block 30 is slidably disposed in the mounting groove 31. A locking ball 29 is embedded in the mounting block 30. Locking grooves 28 that cooperate with the locking ball 29 are provided on both sides of the adjustment block 24. A second spring 32 connected to the mounting block 30 is disposed in the mounting groove 31.

[0048] The second spring 32 is in a compressed state and provides an elastic pushing force to the mounting block 30, so that the locking ball 29 on the mounting block 30 is in a state of extending into the adjustment cavity 25. When the adjustment block 24 is located in the middle of the adjustment cavity 25, the locking ball 29 can be locked into the locking groove 28 of the adjustment block 24 to limit the adjustment block 24. Under the second spring 32, the locking ball 29 can perform rolling and locking movements, which facilitates the movement of the adjustment block 24 in the adjustment cavity 25 and allows the locking ball 29 to freely enter and exit the locking groove 28.

[0049] In one instance of this embodiment, please refer to Figure 1 and Figure 11 A fixing seat 33 is installed in the optical fiber channel 1. The fixing seat 33 is detachably connected to the combing frame 2 and is used to install the combing frame 2 in the optical fiber channel 1. There are various ways to connect the fixing seat 33 and the combing frame 2, which will not be described in detail here.

[0050] This invention enables rapid fiber insertion and deployment by setting a longitudinal fiber optic groove 3 on the combing rack 2, and cooperating with a rotatable rotating plate 7 and an expansion plate 10. This eliminates the cumbersome operation of placing and fixing each layer of the traditional multi-layer combing plate, greatly improving the efficiency of fiber optic cabling. Furthermore, through the cooperation of the limit control component 34 and the drive component 35, the rotating plate 7 and the expansion plate 10 can be flexibly adjusted according to the fiber placement, removal, and limit requirements, making the fiber deployment, limit, and removal more convenient and reliable. The overall structure is simple and reasonable, and the operation is convenient. It can effectively reduce the difficulty of cabling and improve the flexibility of use and maintenance efficiency of the fiber optic groove 1.
