Description

Cable coiling device and optical cable coiling panel Technical Field

[0001] The invention belongs to the field of optical fibers, and in particular relates to a cable coiling device and an optical cable coiling panel. Background Art

[0002] In the application process of optical fibers, optical cables and other cables, there is often a need for cable winding and distribution. Especially in the use of optical cables, since the optical cables have to pass through multiple optical units such as corridor fiber distribution boxes, home entry panels, and transfer equipment in each room, there is often a need for cable winding and distribution during the laying and use of optical cables.

[0003] Currently, fiber optic cable termination panels (FTPs) are commonly used for cable reeling. These devices serve as a transit point between the trunk optical cable and the distribution fiber to individual rooms, and are widely used in the installation and utilization of optical cables. A typical FTP typically consists of a housing, a rotating reeling module, and a corresponding connector module. The panels introduce the optical cable into the housing, perform reeling and distribution within the housing, and then route the optical cable signals from the corresponding optical units through corresponding interfaces.

[0004] Existing optical cable storage panels typically have the primary functions of storage and distribution. After being stored internally, the optical cables are output from the box as either ordinary or invisible optical cables, then connected to the next device port for use. Existing panel-type products can, to a certain extent, meet the needs for cable storage and distribution. However, because the installation location of the storage panel box often varies from the distance to the next connection port, the required output cable type or length also varies, resulting in the pull-out length of the internally stored optical cables often being random. Furthermore, conventional optical cable storage panels lack a function to lock the length of the output cables. This can lead to the continued extraction of cables stored within the panel during subsequent construction due to factors such as accidental pulling or misoperation. This can cause the cables to become excessively long and hang over the edge of the wall, making them less visible and aesthetically pleasing. Furthermore, the installation requires on-site retraction, increasing the cost of laying and using the optical cables. Summary of the Invention

[0041] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0042] (1) The cable reeling device of the present invention comprises a base plate and a central rotating shaft and a rotating reeling member arranged on the base plate. By utilizing the corresponding arrangement of the first connection position and the second connection position on the central rotating shaft, and the corresponding arrangement of the upper limit assembly of the rotating reeling member, the position switching of the central sleeve between the two connection positions is utilized to accurately realize the switching of the rotating reeling member between the rotating state and the locked state, thereby ensuring that the reeling state is locked after the cable is reeled in place, avoiding the phenomenon of accidental pulling out of the cable due to subsequent operations, and improving the aesthetics and accuracy of on-site storage and inventorying.

[0043] (2) The cable winding device of the present invention can quickly realize the formation of two connection positions on the central shaft through the combination of the two hooks in the hook assembly and the ring plate in the center sleeve, realize reliable axial locking between the center sleeve and the center shaft, ensure the convenience and accuracy of the position switching of the center sleeve between the first connection position and the second connection position, and cooperate with the corresponding setting of the corresponding structure of the limit assembly to fully simplify the operating procedures of the cable winding process and the winding locking process of the cable winding device, improve the cable winding accuracy, and further simplify the design of the corresponding structure, thereby reducing the setting cost and use cost of the device.

[0044] (3) The cable coiling device of the present invention, by providing a baffle assembly on the outer periphery of the central sleeve, uses the baffle assembly to divide the coiling space on the outer periphery of the central sleeve into multiple sections, thereby enabling the simultaneous coiling of different cables in layers, facilitating the subsequent separate wiring of different cables, further enhancing the functionality of the cable coiling device, and expanding its scope of application. At the same time, the corresponding arrangement of the ear plate structure on the baffle assembly can further strengthen the axial limit of the cable after coiling, preventing the coiled cable from shifting or spreading, and improving the cable coiling effect.

[0045] (4) The optical cable reeling panel of the present invention has a simple structure and is easy to use. By utilizing the corresponding arrangement of the central rotating shaft and the rotating reeling member inside the panel box, the optical cable and the corresponding optical unit can be accurately reeled and arranged, thereby improving the accuracy and reliability of the optical cable and optical fiber reeling. At the same time, by utilizing the corresponding arrangement of the interface assembly and the corresponding fixing buckles and circular slots inside the box, the corresponding connectors on the optical cable or optical fiber can be quickly plugged in and fixed, ensuring the accuracy and reliability of the corresponding connector components during the cable reeling and wiring process, thereby improving the use effect of the optical cable and optical fiber.

[0046] (5) The optical cable reel panel of the present invention is configured to be detachably connected to the center shaft and the bottom shell, and the bottom shell is configured to have a variety of optional sizes and specifications. In combination with the corresponding configuration of the adapter assembly, the welding slot, etc. in the bottom shells of different specifications, the optical cable reel panel can be used in different application scenarios by replacing the cable reel assembly in different bottom shells, thereby meeting different application requirements and improving the flexibility and convenience of using the optical cable reel panel.

[0047] (6) The optical cable reel panel of the present invention is based on the detachable connection between the central shaft and the bottom shell. By setting the bottom shell as a multifunctional bottom shell and utilizing the corresponding arrangement of multiple installation positions and multiple installation slots in the bottom shell, the cable reel assembly can complete the switching of multiple use states in the same bottom shell, realizing the switching of use states such as center reeling of the optical cable, eccentric reeling, internal plugging of the adapter, and disassembly of the end face of the adapter, further improving the flexibility and functionality of the panel, reducing the use cost of the optical cable reel panel, and improving the use effect.

[0048] (7) The optical cable reel panel of the present invention has a simple structure and is easy to assemble and use. It can quickly realize the storage and winding of cables, ensuring the accuracy and aesthetics of cable arrangement and wiring use, improving the current situation of hanging and messy use during the laying and use of traditional cables, and avoiding the accidental pulling out of the coiled cables due to mis-pulling or mis-tugging after the cable wiring is laid, thereby ensuring the reliability of cable winding and having good practical value.

Example

[0067] Please refer to Figures 1 to 6. The cable winding device in the preferred embodiment of the present invention includes a base plate 1, and a central shaft 2 and a rotating winding member 3 are combined and arranged on the base plate 1. The cable winding position can be formed by fitting the rotating winding member 3 on the central shaft 2.

[0068] Specifically, the central rotating shaft 2 in the preferred embodiment is shown in Figure 2, one end of which is connected to the base plate 1, and the other end is rotationally matched with the rotating disk storage member 3. Corresponding to the rotational matching of the rotating disk storage member 3 on the central rotating shaft 2, at least two connection positions are formed on the central rotating shaft 2, such as the first connection position 205 and the second connection position 206 which are arranged in sequence from far to near relative to the base plate 1.

[0069] The connection between the central shaft 2 and the base plate 1 can be either a fixed connection or a detachable connection.

[0070] At the same time, the rotating disk storage member 3 in the preferred embodiment is shown in Figure 3, which includes a central sleeve 301 that is cylindrical and can be sleeved on the outer periphery of the central rotating shaft 2. The central sleeve 301 can switch positions between two connection positions and achieve axial locking at any connection position.

[0071] Correspondingly, a limit assembly 4 is further provided between the rotating disk storage member 3 and the base plate 1 and / or the central rotating shaft 2, which is in a locked state when the rotating disk storage member 3 is located in the first connection position 205. At this time, the rotating disk storage member 3 is only axially locked relative to the central rotating shaft 2 and can rotate circumferentially around the central rotating shaft 2; when the rotating disk storage member 3 switches from the first connection position 205 to the second connection position 206, the limit assembly 4 switches from an unmatched state to a matched state. At this time, the rotating disk storage member 3 achieves axial locking and circumferential locking in the second connection position 206, ensuring that the stored cables can be reliably fixed.

[0072] More specifically, in a preferred embodiment, the formation of the two connection positions on the central shaft 2 is correspondingly formed depending on the arrangement of the hook assembly at the end of the central shaft 2 .

[0073] In a specific preferred embodiment, the central rotating shaft 2 is a cylindrical structure, one end of which is used to connect to the base plate 1, and the other end is provided with multiple notches along the axial direction, dividing the end of the central rotating shaft 2 into multiple sheet structures arranged at intervals in the annular direction, and then by providing corresponding protruding structures on the outer peripheral wall surface of each sheet structure, a hook assembly as shown in Figure 2 can be formed.

[0074] In more detail, the hook assembly in the preferred embodiment includes at least one first hook 201 and at least one second hook 203. The first hook 201 and the second hook 203 are arranged in an annular manner at the end of the central rotating shaft 2. Both include a rod body extending in the axial direction and a locking protrusion arranged on the outer peripheral wall of the rod, that is, a first protrusion 202 arranged on the outer periphery of the end of the first hook 201 and a second protrusion 204 arranged on the outer periphery of the end of the second hook 203. The two protrusions are arranged at different positions in the axial direction of the central rotating shaft 2.

[0075] Taking the end of the central shaft 2 connected to the base plate 1 as the reference end, the side of the first protrusion 202 away from the reference end (the top surface of the first protrusion 202) is recorded as the first surface 2021, and the side close to the reference end (the bottom surface of the first protrusion 202) is recorded as the second surface 2022; and the side surface of the second protrusion 204 away from the reference end (the top surface of the second protrusion 204) is recorded as the third surface 2041, and the side surface close to the reference end (the bottom surface of the second protrusion 204) is recorded as the fourth surface 2042.

[0076] In a preferred embodiment, the second surface 2022 is preferably a plane perpendicular to the axis of the central rotating shaft 2, and its distance from the reference end is greater than the distance between the fourth surface 2042 and the reference end, and the second surface 2022 and the third surface 2041 are separated by a certain distance in the axial direction of the central rotating shaft 2.

[0077] Preferably, the axial lengths of the rod bodies of the first hook 201 and the second hook 203 can be equal in actual arrangement (the main difference is the different positions of the protrusions arranged on the outer periphery of the rod), or they can be set to be unequal as shown in FIG2 , that is, the first hook 201 is a long hook and the second hook 203 is a short hook.

[0078] Furthermore, in order to ensure the support and limiting reliability of the two hooks during actual use, the two hooks preferably include a plurality of hooks arranged at intervals in the circumferential direction, such as the plurality of hooks arranged at intervals as shown in FIG. 2 .

[0079] At the same time, in the preferred embodiment, the first hook 201 and the second hook 203 are arranged in sequence in the circumferential direction at the end of the central shaft 2 , that is, the first hook 201 is arranged between two adjacent second hooks 203 , and the second hook 203 is arranged between two adjacent first hooks 201 .

[0080] More preferably, in actual setting, since the first surface 2021 of the first protrusion 202 will first match the central sleeve 301 of the rotating disk storage member 3, in a preferred embodiment, the first surface 2021 is preferably set as a wedge surface, so that the thickness of the first protrusion 202 continues to increase as the inner diameter decreases, as shown in Figure 2.

[0081] In addition, in order to facilitate the state switching of the second hook 203 during actual operation, it is preferred that an arc chamfer is provided at the corner of the second protrusion 204 close to the third surface 2041 to facilitate the state switching of the central sleeve 301 by pressing.

[0082] In actual configuration, it is further preferred that arc chamfers are respectively provided at the corners of the two surfaces of the second protrusion 204 to facilitate flexible assembly and disassembly of the central sleeve 301 on the central shaft 2 .

[0083] Furthermore, the rotating disk storage member 3 in the preferred embodiment is shown in Figure 3, which includes a central sleeve 301 that is cylindrical and has an inner diameter larger than the outer diameter of the central shaft 2. A ring plate 302 with a certain width is arranged on the inner circumferential wall surface of one end of the central sleeve 301 in the circumferential direction. The inner diameter of the ring plate 302 is smaller than the outer diameter of the two protrusions, and is further preferably equal to (or slightly larger than) the outer diameter of the central shaft 2. The width thereof is preferably not less than the protruding length of the two protrusions, and is further preferably equal to the length of the protruding surface of the two protrusions, so that after the two protrusions match the ring plate 302, the ends of the two protrusions abut the inner circumferential wall surface of the central sleeve 301 as much as possible.

[0084] At the same time, the thickness of the ring plate 302 is preferably no greater than the axial distance between the second surface 2022 and the third surface 2041, so that the ring plate 302 can be embedded between the two protrusions as needed. In a preferred embodiment, the thickness of the ring plate 302 is preferably equal to the distance between the two protrusions (i.e., the axial distance between the second surface 2022 and the third surface 2041).

[0085] Furthermore, in actual configuration, the second surface 2022 and the fourth surface 2042 are preferably configured as wedge-shaped surfaces (not shown). Accordingly, the top surface of the ring plate 302 is configured as a wedge-shaped surface, resulting in a right-angled trapezoidal cross-section, with the thickness of the ring plate 302 decreasing from the outside to the inside. This configuration ensures that the ring plate 302 can be accurately locked in place in both the rotating and locked states of the rotating disk element 3 by the mating of the corresponding protrusions with the ring plate 302.

[0086] The combination of the two hooks in the hook assembly and the ring plate 302 inside the center sleeve 301 allows the center sleeve 301 to be mounted on and connected to the outer circumference of the center shaft 2. Furthermore, the axial position of the center sleeve 301 relative to the center shaft 2 can be varied depending on the placement of the ring plate 302.

[0087] Among them, when the ring plate 302 is embedded between the second surface 2022 and the third surface 2041, the center sleeve 301 is in a state of being rotationally connected to the center shaft 2, that is, a rotating state. In this state, the center sleeve 301 and the related structures arranged outside the center sleeve 301 can rotate forward or reverse around the center shaft 2.

[0088] Furthermore, a limiting assembly 4 is provided between the rotating disk storage member 3 and the central rotating shaft 2 and / or the base plate 1, so that when the annular plate 302 is embedded below the fourth surface 2042, the limiting assembly 4 can be switched from an unlocked state to a locked state, thereby locking the circumferential rotation of the central sleeve 301, so that the rotating disk storage member 3 is switched from a rotating state to a locked state.

[0089] In actual setting, the specific setting form of the limiting component 4 in the preferred embodiment can be preferably set according to needs.

[0090] In a specific preferred embodiment, the limiting assembly 4 is disposed between the rotating disk storage member 3 and the base plate 1, and includes a first limiting member disposed on the rotating disk storage member 3 and a second limiting member disposed on the base plate 1. When the rotating disk storage member 3 is in a rotating state, the first limiting member and the second limiting member are spaced a certain distance apart and cannot mate with each other. At this time, the limiting assembly 4 is in an unmatched state, and the rotating disk storage member 3 can rotate around its axis as needed. When the rotating disk storage member 3 switches from a rotating state to a locked state, the central sleeve 301 moves a certain distance relative to the central shaft 2 toward the base plate 1. After this movement, the first limiting member mates with the corresponding second limiting member, and the limiting assembly 4 begins to operate, locking the rotating disk storage member 3 in the corresponding position.

[0091] In more detail, in actual setting, the matching method of the first limit member and the second limit member is preferably a matching form of "protrusion" and "groove", and the circumferential rotation limit of the rotating disk storage member 3 is achieved by embedding the protrusion in the groove.

[0092] It can be understood that in actual setting, the limiting member serving as a "protrusion" can be set on the rotating disk storage member 3 or on the base plate 1. At this time, the limiting member serving as a "groove" is correspondingly set on the base plate 1 or on the rotating disk storage member 3.

[0093] As a specific arrangement, the first stopper is a stopper protrusion provided at the end of the central sleeve 301, and the second stopper is a stopper groove provided on the end surface of the base plate 1. When the rotating disk storage member 3 is in the rotating state, the stopper protrusion and the stopper groove are spaced a certain distance apart in the axial direction of the central rotating shaft 2, and the two cannot mate. However, when the stopper protrusion and the stopper groove are rotated to align in the axial direction of the central rotating shaft 2, the central sleeve 301 is pressed, pressing its ring plate 302 from above the second protrusion 204 to below the second protrusion 204, thereby achieving the embedded mating of the stopper protrusion and the stopper groove, thereby locking the stopper assembly 4.

[0094] Of course, it can be understood that as a variation of the above scheme, the limiting protrusion can also be set on the top surface of the base plate 1, and a number of notches can be opened on the end face of the bottom of the center sleeve 301 to serve as limiting grooves. Through the axial movement of the center sleeve 301, the matching between the two can also be achieved.

[0095] In actual setting, in order to facilitate the matching between the limiting protrusion and the limiting groove, it is preferred to set the limiting groove to be slightly larger than the size of the limiting protrusion, so as to facilitate the rapid alignment of the limiting protrusion and the limiting groove.

[0096] Considering that the movement trajectory of the limiting protrusion provided at the end of the central sleeve 301 is in the shape of an arc, in a preferred embodiment, the groove provided on the end surface of the bottom plate 1 is further provided in the shape of an arc.

[0097] To further facilitate quick mating between the first and second stoppers, in another preferred embodiment, the end of the central sleeve 301 is provided with a serrated structure, serving as a continuously provided first stopper. Correspondingly, a corresponding serrated structure (serrated grooves or serrated protrusions) is provided along the circumferential direction on the end surface of the base plate 1, serving as a continuously provided second stopper. In this case, the mutual engagement between the first and second stoppers allows for quick mating of the stopper assembly 4.

[0098] Furthermore, in actual configuration, the first limiting member may be disposed not only directly on the central sleeve 301 but also on a corresponding component disposed on the outer periphery of the central sleeve 301, such as the limiting block 401 disposed on the bottom surface of the fan-shaped blade on the outer periphery of the bottom of the central sleeve 301, as shown in FIG3 . Accordingly, the second limiting member is a limiting groove 402 disposed on the bottom plate 1, and disposed at a position corresponding to the position of the upper limiting block 401 on the fan-shaped blade.

[0099] In the aforementioned preferred embodiment, the limiting assembly 4 is disposed between the central sleeve 301 and the base plate 1 , while in another specific preferred embodiment, the first limiting member and the second limiting member are disposed between the central sleeve 301 and the central shaft 2 .

[0100] Specifically, the first limiting member at this time is preferably a limiting protrusion arranged on the inner circumferential wall surface of the top of the center sleeve 301 and extending radially; accordingly, the second limiting member is preferably a limiting groove opened at the top of the center shaft 2, and the limiting groove is further preferably opened at the end of the first hook 201. When the ring plate 302 is embedded between the second surface 2022 and the third surface 2041, the limiting protrusion and the limiting groove are arranged at a certain distance along the axial spacing of the center shaft 2; and when the ring plate 302 is embedded below the fourth surface 2042, the limiting protrusion is just embedded in the limiting groove, thereby realizing the limitation of the circumferential rotation of the center sleeve 301.

[0101] Of course, in addition to the above method, the limiting component 4 between the center sleeve 301 and the center shaft 2 can also be set to other forms as needed, as long as it can not work when the center sleeve 301 is in the rotating state, and match the work when the center sleeve 301 is switched to the locked state.

[0102] Through the aforementioned corresponding settings between the central shaft 2 and the rotating disk storage member 3, the corresponding settings and state switching and locking of the rotating disk storage member 3 on the base plate 1 can be achieved, ensuring the accuracy of the rotating disk storage member 3 working in different stages.

[0103] In the initial stage of the operation of the rotating disk storage member 3, it can rotate around the central axis 2. At this time, the cable to be coiled can be quickly wound up by rotating the rotating disk storage member 3; accordingly, according to the pay-out requirements of the corresponding cable, the cable coiled on the rotating disk storage member 3 can also be paid out to the corresponding length as needed.

[0104] In the subsequent stage of the operation of the rotating disk storage member 3, the pay-out of the corresponding cables has met the actual needs. At this time, the central sleeve 301 of the rotating disk storage member 3 is pressed axially to switch it from between the first protrusion 202 and the second protrusion 204 to the side of the second protrusion 204 away from the first protrusion 202. At this time, the limit assembly 4 completes the matching, and the circumferential rotation of the rotating disk storage member 3 is locked. Even if the cable led out from the base plate 1 is pulled subsequently, the rotating disk storage member 3 cannot be caused to rotate, thereby ensuring the reliable locking of the rotating disk storage member 3.

[0105] On the basis that the rotating state and the locked state of the rotating disk storage member 3 are achievable, an optimal design is further made for the specific structure of the rotating disk storage member 3 and / or the central shaft 2.

[0106] Specifically, in order to achieve axial limitation of the cable after it is coiled around the periphery of the center sleeve 301, it is preferred to provide at least one group of baffle assemblies 303 on the periphery of the center sleeve 301. When there are multiple groups of baffle assemblies 303, the multiple groups of baffle assemblies 303 are preferably spaced apart in the axial direction of the center sleeve 301, for example, at both ends of the axial direction of the center sleeve 301, as shown in Figure 3.

[0107] More specifically, in actual setting, the baffle assembly 303 can be an annular baffle arranged circumferentially on the outer periphery of the center sleeve 301, or it can be a plurality of fan-shaped baffles 3031 arranged circumferentially on the outer periphery of the center sleeve 301 at intervals, such as the three shown in Figure 3.

[0108] In a specific preferred embodiment, the baffle assemblies 303 are arranged in two groups axially spaced apart, each group of baffle assemblies 303 including three equally spaced sector-shaped baffles 3031, as shown in FIG3 . Furthermore, in the preferred embodiment, the sector-shaped baffles 3031 of two adjacent groups are staggered, that is, any sector-shaped baffle 3031 in one group is aligned with the gap between two adjacent sector-shaped baffles 3031 in the other group.

[0109] In more detail, in order to further limit the coiled cable, in a preferred embodiment, an ear plate 3032 is provided on at least one group of fan-shaped baffles 3031, which is arranged parallel to the fan-shaped baffles 3031 and is connected to the fan-shaped baffles 3031 through an axially arranged connecting plate 3033, and is spaced a certain distance away from the fan-shaped baffles 3031.

[0110] With this arrangement, the cable coil can be placed between the sector baffle 3031 and the ear plate 3032 , and the cable can be wound around the annular column formed by the plurality of connecting plates 3033 in a circumferential direction, as shown in FIG. 12 .

[0111] By correspondingly disposing multiple sets of baffle assemblies 303, the cable winding space on the periphery of the central sleeve 301 can be divided into multiple independent spaces along the axial direction, so that different types of cables can be wound and retained separately.

[0112] For example, in a specific preferred embodiment, the cable coiling device is mainly used for coiling and wiring of optical cables. At this time, different types of optical fiber units can be coiled separately on the periphery of the central sleeve 301, such as the layered coiling of optical fiber units with outer diameters of 0.9 mm, 2.5 mm, and 3.0 mm.

[0113] Furthermore, as an optical cable coiling device, based on the cable coiling device in the preferred embodiment, an optical cable coiling panel 5 as shown in Figures 7 to 17 is further provided, which can be used to meet different optical cable coiling requirements.

[0114] Specifically, the optical cable storage panel 5 in the preferred embodiment includes a bottom shell 501 and an upper cover 502 arranged in pairs, which can be assembled to form a box-like structure with an accommodating cavity. Accordingly, the central shaft 2 is arranged on the inner end face of the bottom shell 501, and the rotating disk storage member 3 can be correspondingly accommodated in the accommodating cavity of the panel after matching with the central shaft 2.

[0115] In actual settings, the connection between the central shaft 2 and the bottom shell 501 can be a fixed connection, as shown in Figure 9, or a detachable connection as shown in Figure 10. This can be optimized according to needs and will not be described here.

[0116] Furthermore, it is understood that to facilitate the introduction of optical cables into the panel and the extraction of corresponding cables from the panel, at least one notch is provided on the bottom shell 501. For example, in the preferred embodiments corresponding to Figures 8 to 17 , the number of notches provided on the outer peripheral sidewall of the bottom shell 501 is a plurality of notches spaced circumferentially.

[0117] More specifically, corresponding interface assemblies 503 are provided within the base housing 501 to facilitate the insertion or removal of corresponding cables, as shown in Figures 15 and 17 . The type, number, and location of the interface assemblies 503 can be varied depending on the desired configuration and usage. In a preferred embodiment, the interface assemblies 503 are adapter assemblies, preferably one or more, with corresponding recesses provided within the base housing 501 for each adapter assembly.

[0118] Obviously, for the optical cable winding panel 5 in the preferred embodiment, it can preferably have two usage forms in actual use. One form is that only a cable winding device is set in the bottom shell 501, which is only used for winding the corresponding optical cable in the box body, as shown in Figure 12; the other form is that a cable winding device and at least one adapter component are simultaneously set in the bottom shell 501, and the optical cable is wound in the box body while the connection of the corresponding interface devices on the optical cable is realized, as shown in Figures 15 and 17.

[0119] In order to facilitate the switching of the cable winding device in the above two usage scenarios, in the preferred embodiment, the central shaft 2 and the bottom shell 501 are set to be detachably connected, and a variety of specifications and forms of bottom shells 501 are provided to be optional. By switching the connection between the central shaft 2 and different bottom shells 501, the optical cable winding needs in different application scenarios can be met.

[0120] Furthermore, in a specific preferred embodiment, by setting the bottom shell 501 as a multifunctional bottom shell, the cable winding assembly composed of the central shaft 2 and the rotating disk storage member 3 can complete the switching between the aforementioned two usage modes within a single bottom shell 501 as needed.

[0121] Specifically, the multifunctional bottom housing of the preferred embodiment has at least two removable mounting locations formed in the middle. By switching the removable mounting location corresponding to the central shaft 2, the position of the cable winding assembly within the bottom housing 501 can be changed accordingly. As can be appreciated from the foregoing description, the removable connection method of the central shaft 2 can be optimized as needed, such as a snap-fit ​​connection, threaded sleeve connection, adhesive connection, screw connection, etc., which will not be detailed here.

[0122] During actual setting, a center installation position is provided in the middle of the multifunctional bottom shell. After the center shaft 2 is installed in the center installation position, the cable winding assembly is located correspondingly in the middle of the bottom shell 501, as shown in Figures 11 and 12. At this time, the use state of the optical cable winding panel 5 is the first form (that is, no adapter assembly is provided in the box body).

[0123] Accordingly, at least one eccentric mounting position is provided on one side of the multifunctional bottom housing's central mounting position, allowing the central shaft 2 to be offset from the center of the bottom housing 501 after corresponding connection. Simultaneously, at least one mounting slot is provided on the other side of the bottom housing 501, facing away from the eccentric mounting position, for corresponding installation of an adapter assembly. This arrangement allows for simultaneous installation of the cable spooling assembly and the adapter assembly within the multifunctional bottom housing. The spooled optical cable can then have its connector / connector end plugged into the corresponding adapter assembly, as shown in Figures 15 and 17. At this point, the optical cable spooling panel 5 is in its second configuration (i.e., both the cable spooling assembly and the adapter assembly are simultaneously installed within the housing).

[0124] As a specific configuration, in a preferred embodiment, the multifunctional bottom housing is configured as shown in FIG10 . A combined slot is provided in the center of the bottom housing, formed by a first fixing slot 5011 and a second fixing slot 5012. The axes of the two fixing slots are arranged parallel and non-overlapping, respectively, to securely connect the central shaft 2. It is readily apparent that the second fixing slot 5012 is the aforementioned central mounting location, while the first fixing slot 5011 is the aforementioned eccentric mounting location.

[0125] In more detail, the two fixing grooves are arc-shaped grooves, and snap-fit ​​protrusions are arranged in pairs at the bottom of the center sleeve 301. As shown in Figure 2, the snap-fit ​​protrusions are engaged with the rotation in the first fixing groove 5011 or the second fixing groove 5012 to quickly fix the center shaft 2 in one of the installation positions.

[0126] Furthermore, a plurality of mounting slots are provided in the housing on the side of the second fixing slot 5012 facing away from the first fixing slot 5011, such as the first mounting slot 5013 and the second mounting slot 5014 shown in FIG10 . The first mounting slot 5013 is preferably an internal mounting slot located on the inner side of the bottom shell 501, and is used for mounting the adapter assembly inside the panel, allowing the corresponding connector connected to the adapter assembly to be accommodated inside the panel, as shown in FIG14 and FIG15 ; the second mounting slot 5014 is preferably an end surface mounting slot located near the end surface of the bottom shell 501, and is used for mounting the adapter assembly near the end surface in the housing, allowing the adapter assembly to be connected to the connector head / connector outside the panel after installation, as shown in FIG16 and FIG17 .

[0127] Further preferably, a welding slot 5015 for installing a welding component is further provided in the multifunctional bottom shell, which is preferably provided at a position near the inner wall of the side plate of the bottom shell 501. By installing the welding component in the slot, the function of welding the cable after the cable is broken can be realized.

[0128] In addition, in order to fix the corresponding cable end connector, in the preferred embodiment, a fixing buckle 504 is provided on the top and / or bottom shell 501 of the rotating disk storage member 3 for buckling and fixing the connector or the connecting head.

[0129] At the same time, for the circular connector, it is further preferred to provide a circular slot 505, which can be set in the bottom shell 501, and can also be correspondingly set on the top of the rotating disk storage member 3.

[0130] For example, in the preferred embodiment shown in Figures 12 and 15, the circular slot 505 and the fixing buckle 504 are arranged opposite to the top of the rotating storage member 3, more specifically, opposite to the inside of the central sleeve 301. This arrangement allows the circular slot 505 to rotate synchronously with the central sleeve 301, and thus allows the connector embedded in the circular slot 505 to move synchronously with the central sleeve 301, thereby ensuring that the cable connected to the cable connector can be reliably stored on the rotating storage member 3.

[0131] For the preferred embodiments corresponding to FIG. 10 to FIG. 17 , the use process is preferably as follows:

[0132] Determine the installation position of the central shaft 2 as needed, and set the adapter assembly in the corresponding installation groove when the central shaft 2 is installed in the first fixed groove 5011. After completing the above settings, set the rotating disk storage member 3 accordingly on the central shaft 2 to form a cable winding assembly. At this time, the rotating disk storage member 3 is in the first connection position 205, that is, the ring plate 302 is between the second surface 2022 and the third surface 2041; thereafter, the connector at one end of the optical cable to be wound is correspondingly embedded in the fixed buckle 504 and the circular card groove 505, and wound around the rotating disk storage member 3 in a clockwise direction (the winding process of the cable can be achieved by rotating the central sleeve 301); after completing the winding of the optical cable, embed the fusion end of the optical cable in the fusion groove 5015 or plug the connector at the end of the optical cable into the corresponding adapter assembly. Finally, press the center sleeve 301 to switch it from the first connection position 205 to the second connection position 206. At this time, the limit assembly switches from the non-working state to the working state, locking the circumferential rotation of the rotating coiling member 3, completing the reliable coiling of the optical cable.

[0133] For the optical cable winding panel 5 in the preferred embodiment, the detachable connection of the central shaft 2 is utilized, and the corresponding settings of the bottom shell 501 of various specifications or the aforementioned multifunctional bottom shell are matched, so that the cable winding assembly composed of the rotating winding member 3 and the central shaft 2 can change the setting state as needed, thereby meeting the application in different application scenarios, and greatly improving the flexibility of use of the optical cable winding panel 5.

[0134] The cable winding device of the present invention has a simple structure and is easy to assemble and use. It can quickly realize the winding and storage of cables, ensuring the accuracy and aesthetics of cable arrangement and wiring use, improving the current situation of hanging and messy use during traditional cable laying and use, and avoiding the accidental pulling out of the wound cables due to mis-pulling or mis-tugging after cable wiring and laying, ensuring the reliability of cable winding and having good practical value.

[0135] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
