Description

Technical Field

[0001] This utility model relates to the field of communication devices, and in particular to an ODF frame that reduces the bending of bare optical fibers. Background Technology

[0002] In fiber optic fusion splicing, two bare optical fibers are fused together to connect the two segments. Bare optical fiber refers to the portion of the fiber containing only the core and cladding after the outer protective structures (such as coatings, buffers, and sheaths) have been removed. It is the core transmission unit of the optical fiber, directly responsible for transmitting optical signals. Its diameter is extremely small (typical bare silica fiber is about 125 micrometers in diameter, only slightly thicker than a human hair), with a yield strength between 3.00 GPa and 3.80 GPa. Its mechanical strength is extremely low, making it highly susceptible to breakage due to bending, friction, or impact. Furthermore, it is affected by other fiber cores in the same optical cable, and once broken, it cannot be re-torn to obtain additional length suitable for fusion splicing. Currently, when performing fiber optic fusion splicing, workers typically need to remove the fusion splice tray (or splice box) from the cabinet. However, existing technology lacks a dedicated support platform, and the splice tray is often placed haphazardly on the ground, on temporary supports, or in the hands of workers, making it difficult to maintain a horizontal and stable position.

[0003] This operating method has significant drawbacks: firstly, unstable placement of the splice tray can easily lead to unexpected bending, pulling, or compression of the internal optical fibers, increasing the risk of fiber breakage and thus affecting the splicing effect or even causing communication interruption; secondly, the lack of a fixed operating platform reduces the convenience of operation for staff, prolongs construction time, and reduces maintenance efficiency. Therefore, providing an ODF frame that can prevent destructive bending of bare fibers during the splicing process is the inevitable choice for solving the construction difficulties of service cutover or obstacle removal within the ODF frame. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an ODF frame that reduces the bending of bare optical fibers and provides construction space for the maintenance of fusion splice trays.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An ODF frame for reducing bare optical fiber bending includes a cabinet, on which one or more support components for supporting optical fiber splice trays are provided. The support components include turntables and support plates. One or more turntables are provided, and one or more turntables are rotatably connected to the cabinet. The two ends of the support plate are slidably connected to the turntables respectively. A splice box is detachably connected to the support plate. The cabinet is provided with a fixing component for providing space for splice box maintenance.

[0006] Furthermore, the support plate is provided with sliding grooves symmetrically at both ends, and the sliding grooves are slidably connected to the corresponding turntables.

[0007] Furthermore, the fixing component includes a workbench A and one or more clamping and fixing parts. The one or more clamping and fixing parts are symmetrically arranged at equal intervals along the axial direction of the cabinet at both ends of the cabinet. The workbench A is fixedly inserted into the corresponding clamping part.

[0008] Furthermore, the clamping and fixing part includes a first fixing part and a second fixing part, both of which are disposed on the cabinet body. The first fixing part and the second fixing part are arranged diagonally. The first fixing part contacts the top of the workbench A, and the second fixing part supports the bottom of the workbench B.

[0009] Furthermore, the number of clamping and fixing parts is the same as the number of support plates.

[0010] Furthermore, the fixing component includes a workbench B, a slider, and a slide groove. Sliders are symmetrically arranged at both ends of the workbench B, and slide grooves are symmetrically arranged at both ends of the cabinet. The sliders are slidably connected in the slide grooves.

[0011] Furthermore, the width of the slider is the same as the width of the groove.

[0012] Furthermore, the slide groove is provided with one or more locking grooves, the locking grooves are connected to the slide groove, and the width of the locking grooves and the slide grooves are the same.

[0013] Furthermore, the slide groove is connected to a storage groove, and the slider is slidably connected to the storage groove.

[0014] Furthermore, the number of locking slots is the same as the number of support plates.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0016] 1. This application provides a stable horizontal support surface for the fusion splice tray by setting up workbench A or workbench B. Workers can remove the fusion splice tray from the support assembly and place it on the workbench for operation, avoiding fiber bending and pulling caused by haphazard placement of the fusion splice tray. This effectively reduces the probability of accidental fiber damage during construction and ensures the quality of the fusion splice.

[0017] 2. The fixing component quickly fixes the worktable A through a diagonal clamping structure, and the fixing component realizes the flexible lifting and locking of the worktable B through the cooperation of the sliding groove and the slider. Both solutions can quickly build the operating platform according to the needs, simplify the operation process, shorten the construction time, and improve the welding efficiency.

[0026] The components include: cabinet 1; turntable 11; support plate 2; sliding groove 21; workbench A3; first fixing part 31; second fixing part 32; workbench B4; slider 41; sliding groove 42; locking groove 43; and storage groove 44. Detailed Implementation

[0027] To address the technical problems mentioned in the background art, this application provides a working platform for workers to reduce the risk of optical fiber breakage during the fusion splicing process. Example 1

[0028] This application includes a cabinet 1, and multiple such units are detachably connected inside the cabinet 1. Figure 1 The support assembly shown is used to support the fusion splice tray. The support assembly includes a support plate 2 and a turntable 11 for supporting the support plate 2. The turntable 11 is rotatably connected to the cabinet 1. The support plate 2 has symmetrically arranged sliding grooves 21 at both ends for enclosing the turntables 11. One or more turntables 11 are rotatably connected within the sliding grooves 21, and these turntables 11 are arranged in an array at equal intervals along the axial direction of the sliding grooves 21. The multiple turntables 11 support the sliding grooves 21, and the turntables 11 rotating around their own axes reduce friction with the sliding grooves 21, making the movement of the support plate 2 smoother. A fiber optic fusion splice tray is detachably connected to the support plate 2 via bolts.

[0029] The cabinet 1 is provided with a fixing component, which includes, for example, the fixing component. Figure 1The workbench A3 and clamping and fixing parts shown are provided. There are one or more clamping and fixing parts, arranged in an equally spaced array at both ends of the cabinet 1 along its axial direction. The number of clamping and fixing parts is the same as the number of support plates 2. The clamping and fixing parts include, as shown... Figure 3 The first fixing part 31 and the second fixing part 32 shown are arranged diagonally. By inserting the top of the worktable A3 between the first fixing part 31 and the second fixing part 32, the two ends of the worktable A3 are clamped together. The second fixing part 32 supports the bottom of the worktable A3, and the first fixing part 31 restricts the top of the worktable A3, so that the worktable A3 cannot be separated from the clamped first fixing part 31 and the second fixing part 32 without the influence of external force.

[0030] When using the device:

[0031] The staff removes the support plate 2 that needs repair from the cabinet 1, inserts the workbench A3 into the fixing component below the corresponding support plate 2, removes the splice box from the support plate 2 and places it in the workbench A3. The workbench A3 supports the splice box so that it can be placed horizontally, providing a platform for the staff to operate, reducing the bending of the optical fiber inside the splice box, and thus reducing accidental damage to the optical fiber during construction. Example 2

[0032] Based on Example 1, this example provides a work platform that can be stored to prevent accidental loss due to random placement.

[0033] The cabinet 1 is provided with a fixing component, which includes, for example, the fixing component. Figure 7 The workbench B4 and slide rail 42 are shown. The slide rail 42 is symmetrically arranged on the inner walls of both ends of the cabinet 1. Slider blocks 41 are symmetrically arranged at both ends of the workbench B4. The sliders 41 are rotatably connected to the workbench B4 and slidably connected within the slide rail 42. The inner wall of the slide rail 42 fits against the outer wall of the slider 41. The tight fit between the slider 41 and the slide rail 42 restricts the movement of the workbench B4, allowing it to slide only along the length of the slide rail 42. To facilitate locking the workbench B4 at a specified height, the slide rail 42 is provided with one or more locking slots 43. The slide rail 42 communicates with the locking slots 43. The locking slots 43 are arranged in an array at equal intervals along the axial direction of the cabinet 1. The number of locking slots 43 is the same as the number of support plates 2. When it is necessary to lock the workbench B4, pull the workbench B4 to the specified height and then push the workbench B4 toward the locking groove 43, so that the slider 41 slides into the locking groove 43 to support the workbench B4 and ensure that the workbench B4 can be maintained at the specified height without human intervention.

[0034] To facilitate the storage of workbench B4, a storage slot 44 is provided on the slide 42. The storage slot 44 is located at the bottom of the cabinet 1. The slider 41 slides along the storage slot 44, so that the workbench B4 can slide along the bottom of the cabinet 1, and the bottom of the workbench B4 can fit against the bottom of the cabinet 1 for easy storage.

[0035] When using the device:

[0036] According to the maintenance requirements, the staff will pull out the target support plate 2 and separate the welding plate connected to it from the support plate 2. The workbench B4 will be pulled out from the storage slot 44 and moved along the slide 42 to the corresponding locking slot 43 so that the workbench B4 can be locked. The staff will place the welding plate on the surface of the workbench B4 for maintenance. After the maintenance is completed, the welding plate will be installed on the support plate 2. After pushing the support plate 2 back to its original position, the workbench B4 will be moved into the storage slot 44 for storage.
