Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically a modular optical fiber winding structure integrated within a height-enhancing frame. Background Technology

[0002] As communication technology upgrades to 100G / 400G single-wavelength rates, the port density per slot in communication cabinets has increased to 20 to 32, resulting in an exponential increase in the number of fiber optic cables. The traditional internal space for fiber optic cable management can no longer meet the storage needs.

[0003] Currently, existing fiber optic coiling devices in communication cabinets have the following drawbacks: the coiling space is limited to the area between the cabinet's inner shell and the equipment subrack, making it too small to accommodate the high-density port fiber optic cable storage requirements; the additional fiber optic coiling cabinet occupies valuable space in the equipment room and is difficult to coordinate with the main cabinet for deployment; existing fiber optic coiling devices lack effective dustproof design, and the dusty environment of the equipment room can easily lead to fiber optic connector contamination, affecting transmission performance; and most fiber optic coiling devices are fixed structures, making disassembly and maintenance inconvenient and unable to accommodate fiber optic cables of different lengths. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of space occupation and poor dust prevention in existing fiber optic coiling devices, this utility model proposes a modular fiber optic coiling structure integrated within a height-increasing frame.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a modular fiber optic coiling structure integrated in a height-increasing frame, including a cabinet, a height-increasing frame fixedly connected to the top of the cabinet, a double door on one side of the height-increasing frame, a support plate in the inner cavity of the height-increasing frame, and a fiber coiling device on one side of the support plate. The fiber coiling device includes a rotating shaft, which is rotatably connected to a support plate via a bearing. A fiber coiling tube is fixedly connected to one end of the rotating shaft. Multiple fiber optic clips are fixedly connected to the outer side of the fiber coiling tube. A telescopic tube is slidably connected to the inner wall of the fiber coiling tube. A through hole is opened on the surface of the fiber coiling tube, which penetrates the inner cavity of the telescopic tube. An arc-shaped dust cover is provided on the outer side of the fiber coiling tube. One end of the arc-shaped dust cover is fixedly connected to one side of the support plate. An arc-shaped door is slidably connected to the inner cavity of the arc-shaped dust cover.

[0006] Preferably, the surface of the telescopic cylinder is provided with a placement hole, and a compression spring is fixedly connected to the inner cavity of the placement hole. The other end of the compression spring is fixedly connected to a limiting hemisphere through a round seat, and the limiting hemisphere is slidably connected to the inner wall of the fiber coil.

[0007] Preferably, the inner wall of the fiber disc is provided with a limiting groove, and the limiting hemisphere is used in conjunction with the limiting groove.

[0008] Preferably, a locking mechanism is fixedly connected to one side of the support plate. The locking mechanism includes a fixed plate, and a guide rod is slidably connected to the inner cavity of the fixed plate. A round cover is fixedly connected to one end of the guide rod, and a limiting spring is sleeved on the surface of the guide rod. One end of the limiting spring is fixedly connected to one side of the round cover, and the other end of the limiting spring is fixedly connected to one side of the fixed plate. The guide rod is located on one side of the rotating shaft.

[0009] Preferably, the surface of the rotating shaft is provided with positioning holes, and multiple positioning holes are provided, which are used in conjunction with the guide rod.

[0010] Preferably, an L-shaped bracket is fixedly connected to the other side of the support plate, and a sliding frame is fixedly connected to the inner wall of the heightening frame. The sliding frame slides in conjunction with the L-shaped bracket of the support plate, and an elastic card is rotatably connected to one end of the sliding frame.

[0011] Preferably, the inner wall of the height-increasing frame is provided with a power cord binding assembly, the power cord binding assembly includes a mounting plate, the mounting plate is fixedly connected to the inner wall of the height-increasing frame, and a locking sleeve is fixedly connected to one side of the mounting plate, and multiple locking sleeves are provided.

[0012] The advantages of this utility model are: This utility model incorporates a fiber coiling mechanism. The arc-shaped door and arc-shaped dust cover within the coiling mechanism slide together and fit tightly at the edges after closure. Combined with the overall protection of the raised frame's double-leaf doors, this forms a dual dustproof structure with an arc-shaped door and double-leaf doors. This effectively isolates the computer room from dust, preventing transmission failures caused by dust contamination of fiber optic connectors. The telescopic cylinder's length is freely adjustable to accommodate both long and short pigtails, further enhancing structural adaptability. The fiber optic clips utilize a flexible arc-shaped structure, ensuring a pigtail bending radius ≥30mm while securing multi-layered coiled pigtails in layers and areas. This prevents pigtails from becoming loose or tangled due to equipment vibration, transportation bumps, or maintenance operations. The fiber coiling structure utilizes the unused space at the top of the cabinet, eliminating the need for an additional fiber coiling cabinet and significantly saving horizontal floor space in the computer room. Furthermore, different sizes of raised frames are configured with corresponding numbers of fiber coiling cylinders to accommodate pigtail storage needs at different densities. The support plate uses an L-shaped... The shaped bracket and the sliding frame slide together, and the elastic card can quickly lock or unlock. The fiber coiling device can be pulled out or disassembled without disassembling the overall structure, which greatly reduces the difficulty of maintenance of the tail fiber protector and the fiber coiling device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a modular fiber optic winding structure integrated within a height-enhancing frame. (Refer to...) Figure 1 , Figure 2 and Figure 3A modular fiber optic coiling structure integrated within a height-enhancing frame includes a cabinet 1, a height-enhancing frame 2 fixedly connected to the top of the cabinet 1, a double door 201 on one side of the height-enhancing frame 2, a support plate 3 in the inner cavity of the height-enhancing frame 2, and a fiber coiling device 4 on one side of the support plate 3. The fiber optic coiling device 4 includes a rotating shaft 41, which is rotatably connected to a support plate 3 via a bearing. A fiber optic coil 42 is fixedly connected to one end of the rotating shaft 41. Multiple fiber optic clips 43 are fixedly connected to the outer side of the fiber optic coil 42. A telescopic cylinder 44 is slidably connected to the inner wall of the fiber optic coil 42. A through hole 45 is opened on the surface of the fiber optic coil 42, penetrating the inner cavity of the telescopic cylinder 44. An arc-shaped dust cover 46 is provided on the outer side of the fiber optic coil 42. One end of the arc-shaped dust cover 46 is fixedly connected to one side of the support plate 3. An arc-shaped door 47 is slidably connected to the inner cavity of the arc-shaped dust cover 46. By setting a height-increasing frame 2 on the top of the cabinet 1 and installing the fiber optic coiling device 4 inside the height-increasing frame 2, the unused space at the top of the cabinet 1 is utilized, eliminating the need for an additional fiber optic coiling cabinet and saving water in the server room. Flat area, suitable for high-density port fiber optic cable storage. If the communication equipment cabinet 1 is 2200 (2000) * 600 * 300 mm, then the heightening frame size is 400 * 600 * 300 mm. If the communication equipment cabinet 1 is 2200 (2000) * 600 * 600 mm, then the heightening frame size is 400 * 600 * 600 mm. If the heightening frame size is 400 * 600 * 300 mm, there are two fiber optic coils 42 on each side. If there are three fiber optic coils 42 on each side, then the heightening frame size is 400 * 600 * 600 mm. If a person is facing the direction of cabinet 1, then the fiber optic coils 42 are on the left and right sides of the heightening frame. They are located at the top of cabinet 1, the upper and lower ends of the heightening frame 2, the arc-shaped door 47, and the arc-shaped dustproof door. A wire hole is provided on the cover 46 to facilitate the passage of optical fibers. An optical fiber clip 43 is provided, which has a flexible arc-shaped structure. When the pigtail is coiled, it must be inserted into the arc-shaped groove to ensure that the bending radius of the pigtail is ≥30mm. After coiling, the pigtail is securely fixed by the clips, preventing it from falling off or loosening from the coiling cylinder 42 due to equipment vibration, transportation bumps, or maintenance operations. Multiple clips are evenly distributed along the axial direction of the coiling cylinder 42, fixing the multi-layered coiled pigtail in layers and areas, preventing the pigtail from loosening or tangling due to equipment vibration or maintenance operations. A telescopic cylinder 44 is provided; when extended, it increases the overall length of the coiling cylinder 42, expanding the axial space for pigtail coiling and allowing for more coiling layers. When shortened, it reduces space occupation, adapting to the storage of short pigtails. Hole 45 provides a channel for the fiber optic cable to pass through or out, especially when multiple layers are coiled. The inner layer of the fiber optic cable can be led out through hole 45 to fiber optic clip 43 for fixation, avoiding difficulties in threading caused by the surface layer of the fiber optic cable blocking, and improving the standardization of cabling. The curved door 47 slides open or close along the inner cavity of the curved dust cover 46. When opening, the other side of the curved door 47 needs to be flipped to the side of the dust cover, so that one side of the curved door 47 slides along the inner cavity of the dust cover, which can completely expose the operating area of ​​the fiber optic coil 42 without occupying extra space. When closed, it fits tightly with the edge of the curved dust cover 46. Together with the overall protection of the double doors 201 of the heightening frame 2, a double dustproof structure of curved door 47 and double doors 201 is formed, which effectively isolates the dust in the computer room, avoids fiber optic connector contamination, and is suitable for dusty computer room environments.Furthermore, a handle is provided on the outer side of the curved door 47 for easy control and operation; Reference Figure 3 and Figure 4 The telescopic cylinder 44 has a placement hole 441 on its surface. A compression spring 442 is fixedly connected to the inner cavity of the placement hole 441. The other end of the compression spring 442 is fixedly connected to a limiting hemisphere 443 via a round seat. The limiting hemisphere 443 is slidably connected to the inner wall of the fiber coil 42. A limiting groove 421 is provided on the inner wall of the fiber coil 42. The limiting hemisphere 443 cooperates with the limiting groove 421. When the telescopic cylinder 44 slides out along the inner wall of the fiber coil 42, the limiting hemisphere 443 on the telescopic cylinder 44 slides along the inner wall of the fiber coil 42 under the elastic force of the compression spring 442. When the telescopic cylinder 44 slides to a specific position, the limiting hemisphere 443... The telescopic cylinder 44 is fixed in the limiting groove 421 on the fiber coil 42, preventing it from detaching from the fiber coil 42. When the telescopic cylinder 44 needs to be retracted, a certain external force is applied to it. Due to the smooth circular structure of the limiting hemisphere 443 and its fixed connection with the compression spring 442, the limiting hemisphere 443 disengages from the limiting groove 421 after being subjected to a certain external force. This causes the compression spring 442 to be squeezed, causing the limiting hemisphere 443 to retract towards the inner wall of the placement hole 441. The surface of the limiting hemisphere 443 slides along the inner wall of the fiber coil 42 until the telescopic cylinder 44 is fully retracted. Reference Figure 3 and Figure 4A locking mechanism 5 is fixedly connected to one side of the support plate 3. The locking mechanism 5 includes a fixed plate 51, and a guide rod 52 is slidably connected to the inner cavity of the fixed plate 51. A round cover 53 is fixedly connected to one end of the guide rod 52, and a limiting spring 54 is sleeved on the surface of the guide rod 52. One end of the limiting spring 54 is fixedly connected to one side of the round cover 53, and the other end of the limiting spring 54 is fixedly connected to one side of the fixed plate 51. The guide rod 52 is located on one side of the rotating shaft 41. The rotating shaft 41 has multiple positioning holes 411 on its surface. The positioning holes 411 cooperate with the guide rod 52. By setting the locking mechanism 5, the guide rod 52 in the locking mechanism 5 is inserted and cooperated with the positioning holes 411 to fix the rotating shaft 41, which plays a stabilizing role and prevents the rotating shaft 41 from rotating on its own, thus preventing the fiber coiling. The rotation of the tube 42 affects the stability of the optical fiber on the fiber optic tube 42. When it is necessary to rotate the shaft 41 to adjust the pigtail on the fiber optic tube 42, the round cover 53 at one end of the guide rod 52 is pulled to disengage the guide rod 52 from the positioning hole 411, thereby realizing the rotation of the shaft 41. At the same time, the limiting spring 54 is also in a stretched state as the guide rod 52 is pulled out. When the pigtail is adjusted, the restriction on the round cover 53 is manually released. Under the elastic force of the limiting spring 54, the guide rod 52 is quickly inserted into the positioning hole 411 on the shaft 41, so that the guide rod 52 locks the shaft 41 and prevents the shaft 41 from rotating, thus completing the locking. By setting multiple positioning holes 411, it is convenient for the shaft 41 to quickly and accurately complete the insertion and cooperation with the guide rod 52 after rotation. Reference Figure 1 and Figure 5 An L-shaped bracket 31 is fixedly connected to the other side of the support plate 3. A sliding frame 6 is fixedly connected to the inner wall of the heightening frame 2. The sliding frame 6 and the L-shaped bracket 31 of the support plate 3 are slidably engaged. An elastic card 61 is rotatably connected to one end of the sliding frame 6. One side of the elastic card 61 abuts against one end of the L-shaped bracket 31. By sliding the support plate 3 and the sliding frame 6, the support plate 3 can be pulled out along the sliding frame 6, so that the fiber coil device 4 located on one side of the support plate 3 can be quickly disassembled without disassembling the overall structure, which is convenient for maintenance. By rotating the elastic card 61, the support plate 3 placed in the sliding frame 6 can be fixed, preventing the heightening frame 2 from shaking and causing the support plate 3 to slide out of the sliding frame 6 and fall off. Reference Figure 1 and Figure 2The inner wall of the riser frame 2 is provided with a power cord binding assembly 7. The power cord binding assembly 7 includes a mounting plate 71, which is fixedly connected to the inner wall of the riser frame 2. A locking sleeve 72 is fixedly connected to one side of the mounting plate 71. Multiple locking sleeves 72 are provided. By adding the power cord binding assembly 7, it is mainly used to standardize the laying of power cords from top to bottom of the PDU, maximize the space on both sides of the riser frame, realize the separate laying of power cords and pigtails, avoid cross-tangling, free up fiber coil space, and improve the safety and aesthetics of wiring.

[0018] Working principle: The riser frame 2 is first fixed to the top of the cabinet 1. The support plate 3 is installed by sliding the L-shaped bracket on one side with the sliding groove frame 6 on the inner wall of the riser frame 2. The elastic clip 61 at the end of the sliding groove frame 6 abuts against the end of the L-shaped bracket to achieve a stable fixation of the support plate 3 and prevent the riser frame 2 from shaking and causing the support plate 3 to slide out. The mounting plate 71 of the power cord binding assembly 7 is fixed to the inner wall of the riser frame 2 for subsequent power cord laying and fixing. Open the double doors 201 of the riser frame 2 and the arc-shaped door 47 of the arc-shaped dust cover 46, according to the length of the pigtail. When the telescopic cylinder 44 is pulled outward, the limiting hemisphere 443 in the placement hole 441 on the surface of the telescopic cylinder 44 slides along the inner wall of the fiber coil 42 under the elastic force of the compression spring 442. When it slides to the position of the limiting groove 421, the limiting hemisphere 443 is engaged in the limiting groove 421, completing the extension and fixation of the telescopic cylinder 44. When it needs to be retracted, an external force is applied to make the limiting hemisphere 443 squeeze the compression spring 442 and disengage from the limiting groove 421, pushing the telescopic cylinder 44 to reset. The tail fiber is then coiled along the fiber coil 42. During the coiling process... The pigtail is inserted into the elastic arc-shaped groove of the fiber optic clip 43, ensuring that the bending radius of the pigtail is ≥30mm. When multiple layers are coiled, the inner layer pigtail is led out through the through hole 45 on the surface of the coiling cylinder 42 or the telescopic cylinder 44 and inserted into the corresponding fiber optic clip 43 to achieve layered and area-based fixation. If it is necessary to accommodate pigtails of different lengths, pull the round cover 53 of the locking mechanism 5 to drive the guide rod 52 to disengage from the positioning hole 411 of the rotating shaft 41. After rotating the rotating shaft 41 to the target angle, release the round cover 53, and the guide rod 52 is inserted into the corresponding positioning hole under the reset force of the limit spring 54. Position hole 411 locks the rotating shaft 41 to prevent the fiber coil 42 from rotating on its own. After the fiber coiling is completed, the arc-shaped door 47 and the double doors 201 of the heightening frame 2 are closed to form a double dustproof structure of arc-shaped door 47 and double doors 201. When the fiber coiling device 4 needs to be maintained or replaced, rotate the elastic card 61 to make it disengage from the L-shaped bracket, and pull out the support plate 3 along the slide frame 6 to remove the entire fiber coiling device 4 without disassembling the entire structure of the heightening frame 2. When the power cord is laid, it is inserted into the locking sleeve 72 of the power cord binding component 7 to achieve separate laying from the pigtail. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
