[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] like Figures 1 to 13 As shown, some embodiments of this utility model provide a cable storage structure, including a panel structure 10 and a cable reel 20. The panel structure 10 includes a housing 11 and a positioning shaft 12. The housing 11 has a cavity for receiving the cable reel 20, and the positioning shaft 12 is disposed on the inner wall of the cavity of the housing 11. The cable reel 20 is used to wind the cable. The cable reel 20 has a shaft hole. At least a portion of the positioning shaft 12 is detachably inserted into the shaft hole and limited to restrict the movement of the cable reel 20 along the axial direction of the positioning shaft 12. The panel structure 10 has a first limiting structure, and the cable reel 20 has a second limiting structure. The first limiting structure and the second limiting structure are limited to restrict the rotation of the cable reel 20 in the circumferential direction of the positioning shaft 12.

[0036] The cable can be a fiber optic patch cord, which is an integrated component consisting of an optical fiber and one or more fiber optic connectors. The panel structure 10 can specifically be a fiber optic socket box.

[0037] In these embodiments, the cable reel 20 is used for winding cables. The cable reel 20 has a shaft hole into which at least a portion of the positioning shaft 12 of the panel structure 10 can be inserted. After the two are connected, the cable reel 20 is installed in the cavity of the panel structure 10 to store the cable reel 20 and the cables wound on it. The axial movement of the cable reel 20 along the positioning shaft 12 is limited by the limiting fit between the positioning shaft 12 and the shaft hole. The rotation of the cable reel 20 in the circumferential direction of the positioning shaft 12 is limited by the first and second limiting structures. This ensures that the cable reel 20 is reliably stored within the panel structure 10, preventing it from detaching. Furthermore, the detachable connection between the positioning shaft 12 and the shaft hole of the cable reel 20 facilitates cable winding or use, improving the flexibility of the cable storage structure.

[0038] In some embodiments, the positioning shaft 12 comprises a connecting portion and a clamping portion, one end of the connecting portion is arranged on the inner wall of the cavity of the shell 11, and the clamping portion is arranged on the other end of the connecting portion; wherein the connecting portion is a structure that can be elastically deformed in the radial direction of the positioning shaft 12, the connecting portion penetrates the shaft hole, and the clamping portion is limitedly matched with the end face of the cable reel 20 after penetrating the shaft hole, so as to realize the axial limiting cooperation between the panel structure 10 and the cable reel 20 in the positioning shaft 12.

[0039] After the connecting portion penetrates the shaft hole of the cable reel 20, the cable reel 20 is supported and radially limited, and since the connecting portion can be elastically deformed in the radial direction of the positioning shaft 12, the clamping portion can penetrate the shaft hole through the elastic deformation of the connecting portion. After the clamping portion penetrates the shaft hole, the connecting portion returns to the state before deformation, and the clamping portion is limitedly matched with the end face of the cable reel 20, thereby realizing the axial limiting cooperation between the panel structure 10 and the cable reel 20 in the positioning shaft 12. Therefore, after the clamping of the positioning shaft 12 and the cable reel 21, the locking between the cable reel 20 and the panel structure 10 can be realized, which prevents the cable reel 20 from moving axially unnecessarily due to external force or its own gravity after wiring is completed, thereby ensuring the stability of the cable. The clamping portion is used to realize fixation, which simplifies the installation steps of the cable reel 20, saves the occupied space, and improves the appearance and stability of the overall layout of the cable.

[0040] Specifically, as shown in Figure 3 the connecting portion comprises a plurality of connecting columns 122, and the plurality of connecting columns 122 are arranged around the axis of the shaft hole and can be elastically deformed in the radial direction of the positioning shaft 12; the clamping portion comprises a plurality of clamping hooks 121, and the plurality of clamping hooks 121 penetrate the shaft hole and are arranged around the axis of the shaft hole. One end of each connecting column 122 is arranged on the inner wall of the cavity of the shell 11, and the other end of each connecting column 122 corresponds to one clamping hook 121. Each clamping hook 121 is limitedly matched with the end face of the cable reel 20.

[0041] In this embodiment, the cable reel 20 is supported and radially limited by the plurality of connecting columns 122, and the corresponding clamping hook 121 can penetrate the shaft hole through the elastic deformation of the connecting column 122. After the clamping hook 121 penetrates the shaft hole, the connecting column 122 returns to the state before deformation, and the clamping hook 121 is limitedly matched with the end face of the cable reel 20, thereby realizing the axial limiting cooperation between the panel structure 10 and the cable reel 20 in the positioning shaft 12. Therefore, by arranging a plurality of clamping hooks 121, the axial locking of the cable reel 20 in the cavity of the shell 11 is ensured, which prevents the cable reel 20 from being axially detached from the positioning shaft 12 due to external force or its own gravity, avoids damage to the cable wound on the cable reel 20 due to accidental movement of the cable reel 20, and ensures the neatness and beauty of cable storage.

[0042] In some embodiments, the cable reel 20 comprises a cable shaft 21 and a limiting portion 22, the cable shaft 21 is provided with a shaft hole for winding the cable, and the limiting portion 22 is arranged at the end of the cable shaft 21 to limit the wound cable; wherein the first limiting structure and the second limiting structure are respectively arranged on the inner wall of the cavity of the shell 11 and the limiting portion 22.

[0043] In some embodiments, the cable reel 20 comprises a cable shaft 21 and a limiting portion 22, the cable shaft 21 is provided with a shaft hole for winding the cable, and the limiting portion 22 is arranged at the end of the cable shaft 21 to limit the wound cable; wherein the first limiting structure and the second limiting structure are respectively arranged on the inner wall of the cavity of the shell 11 and the limiting portion 22.

[0044] The cooperation of the first limiting structure and the second limiting structure limits the relative movement of the panel structure 10 and the cable reel 20 in the circumferential direction of the cable shaft 21, prevents the cable reel 20 from rotating due to external force or the self-gravity of the cable during use, avoids the loosening of the cable, and ensures the stability of the winding and storage of the cable. The first limiting structure, the second limiting structure, and the positioning shaft 12 work together to not only achieve the radial positioning of the cable reel 20 but also ensure the stability of the cable reel 20 in the circumferential direction, avoid the loosening or damage of the cable caused by the movement or rotation of the cable reel 20, and improve the wiring efficiency and reliability. The first limiting structure and the second limiting structure can be arranged at different positions and selected as needed.

[0045] Among them, one of the first limiting structure and the second limiting structure is a protrusion 31, and the other is a groove 32 corresponding to the protrusion 31, and the protrusion 31 is correspondingly clamped into the groove 32 to limit the rotation of the cable reel 20 in the circumferential direction of the positioning shaft 12.

[0046] In some embodiments, as shown in Figure 2 and Figure 3 , the first limiting structure comprises a protrusion 31 arranged on the inner wall of the cavity, and the second limiting structure comprises a groove 32 arranged on the limiting portion 22, and after the cable reel 20 is installed on the positioning shaft 12 through the shaft hole, the protrusion 31 can be clamped into the groove 32; or, as shown in Figure 4 and Figure 5 , the first limiting structure comprises a groove 32 arranged on the inner wall of the cavity, and the second limiting structure comprises a protrusion 31 arranged on the limiting portion 22, and after the cable reel 20 is installed on the positioning shaft 12 through the shaft hole, the protrusion 31 can be clamped into the groove 32.

[0047] The design of the first and second limiting structures adopts the cooperation of protrusions 31 and grooves 32. When the cable reel 20 is installed in the cavity of the panel structure 10, the protrusions 31 can accurately fit into the grooves 32, realizing the axial positioning and circumferential anti-rotation of the cable reel 20, ensuring the stability and reliability of the cable reel 20. Moreover, this design is simple in structure, saves the volume occupied by the equipment lock, and improves the versatility of the cable reel 20 and the aesthetics of the wiring.

[0048] In some embodiments, there are multiple protrusions 31 and multiple grooves 32, and the multiple protrusions 31 and multiple grooves 32 are arranged in a one-to-one correspondence; multiple elastic arms 13 are provided on the inner wall of the cavity, and each elastic arm 13 is provided with at least one protrusion 31 and / or at least one groove 32.

[0049] To further enhance the fixing effect and provide an elastic limiting function, multiple elastic arms 13 are provided on the inner wall of the cavity. Each elastic arm 13 has at least one protrusion 31 and / or at least one groove 32 to provide an elastic limiting function for the cable reel 20. This allows the cable reel 20 to automatically lock when rotated to a fixed position. The operation is simple and convenient, ensuring that the cable reel 20 can be firmly fixed in a confined space. This reduces the complexity of the installation process, improves installation efficiency and stability, and also provides convenience for subsequent maintenance and adjustment.

[0050] Specifically, the inner wall of the cavity is provided with an opening, one end of the elastic arm 13 is connected to the wall of the opening, and the other end of the elastic arm 13 is suspended. The suspended end of the elastic arm 13 is provided with a protrusion 31 and / or at least one groove 32.

[0051] In some embodiments, such as Figure 6 , Figure 7 As shown, the first limiting structure includes a protrusion 31 disposed on the positioning shaft 12, and the second limiting structure includes a groove 32 disposed on the inner wall of the shaft hole. After the cable reel 20 is installed on the positioning shaft 12 through the shaft hole, the protrusion 31 is engaged in the groove 32; or, the first limiting structure includes a groove 32 disposed on the positioning shaft 12, and the second limiting structure includes a protrusion 31 disposed on the inner wall of the shaft hole. After the cable reel 20 is installed on the positioning shaft 12 through the shaft hole, the protrusion 31 is engaged in the groove 32.

[0052] The design of the first limiting structure and the second limiting structure adopts the matching mode of the protrusion 31 and the groove 32. When the cable reel 20 is installed in the cavity of the panel structure 10, at least a part of the positioning shaft 12 is inserted into the shaft hole of the cable shaft 21, and the protrusion 31 and the groove 32 arranged on the positioning shaft 12 and the shaft hole of the cable shaft 21 can be well matched, axial positioning and circumferential anti-rotation of the cable reel 20 are realized, and the stability and reliability of the cable reel 20 are ensured. The design simplifies the operation steps of fixing and adjusting the cable reel 20, and improves the wiring efficiency and aesthetic appearance of the user in a limited space.

[0053] As shown in Figures 2 to 9 The protrusion 31 is semispherical or polygonal, and the groove 32 is semispherical or polygonal in shape matched with the shape of the protrusion 31.

[0054] In the embodiment, the protrusion 31 is semispherical or polygonal, and the shape of the protrusion 31 and the groove 32 matched with the shape of the protrusion 31 can be flexibly selected according to the actual use scene, the flexibility of the cable storage structure is improved, no additional tools or complex operation steps are required, the installation process of the cable reel 20 is simplified, and the stable fixation of the cable reel 20 in the cavity of the panel structure 10 is ensured.

[0055] In some embodiments, the positioning shaft 12 includes a plurality of clamping hooks 121, and the plurality of clamping hooks 121 pass through the shaft hole and are clamped; the protrusion 31 and the groove 32 are both a plurality of, and the plurality of protrusions 31 and the plurality of grooves 32 are one-to-one corresponding arrangement, wherein at least one protrusion 31 and / or at least one groove 32 are arranged on each clamping hook 121.

[0056] In the embodiment, the protrusion 31 and the groove 32 are both designed as a plurality of and one-to-one corresponding arrangement, which ensures that the cable reel 20 can be locked at a set position to avoid unnecessary rotation, and at least one protrusion 31 and / or at least one groove 32 are arranged on each clamping hook 121, so that the clamping hook 121 can not only realize the stable fixation of the cable reel 20 in the radial direction, but also limit the axial rotation of the cable reel 20 through the matching of the protrusion 31 and the groove 32, thereby simplifying the installation process.

[0057] In some embodiments, the shell 11 and the positioning shaft 12 are an integral structure or a split structure.

[0058] In the embodiment, if the shell 11 and the positioning shaft 12 are in an integrated structure, the assembly steps are simplified, the production efficiency is improved, and the stability of the connection between the shell 11 and the positioning shaft 12 is ensured; if the shell 11 and the positioning shaft 12 are in a split structure, higher flexibility is provided, the appropriate installation mode can be selected according to different application scenarios, for example, screw fixing, gluing, etc., and when the positioning shaft 12 is damaged, the positioning shaft 12 can be replaced alone without replacing the entire panel structure 10, the flexibility of the cable storage structure is improved, and the maintenance difficulty and cost are reduced.

[0059] In some embodiments, the cable storage structure further comprises a cable, and the cable is wound on the cable shaft 21 of the cable reel 20. The cable can be an optical fiber jumper, which is an assembly integrating an optical fiber and one or more optical fiber connectors.

[0060] The cable is wound on the cable shaft 21 of the cable reel 20, which is only installed in the panel structure 10. Taking the cable as an optical fiber as an example, the cable reel 20 of the cable storage structure has optical fibers wound therein, and one end of each optical fiber is provided with an optical fiber connector, and different optical fiber connectors are connected through an adapter. The cable reel 20 is detachably installed in the panel structure 10.

[0061] In some embodiments, the cable reel 20 comprises a cable shaft 21 and a limiting portion 22, the cable shaft 21 is provided with a shaft hole and is used for winding the cable, and the limiting portion 22 is arranged at the end of the cable shaft 21 to limit the wound cable; wherein the size of the limiting portion 22 is adjustable along the axial direction and / or the radial direction of the cable shaft 21.

[0062] The size of the limiting portion 22 is adjustable along the axial direction of the cable shaft 21. For example, in the case that the limiting portion 22 can effectively block the cable, the number of turns of the cable with an outer diameter of 130 μm wound on the cable shaft 21 is 20 turns; when it is necessary to wind the cable with an outer diameter of 125 μm on the cable shaft 21, the outer diameter of the cable wound on the cable shaft 21 is reduced by 20 turns, which may increase the difficulty of taking out the cable from the cable shaft 21 in the diameter direction of the cable shaft 21. Therefore, the length of the cable shaft 21 remains unchanged, the thickness of the limiting portion 22 is increased, the number of turns of the cable with an outer diameter of 125 μm wound on the cable shaft 21 in the length direction is reduced, the number of turns of the cable wound on the cable shaft 21 in the diameter direction is increased, and the limiting portion 22 can exactly block and bind the cable with an outer diameter of 125 μm wound on the cable shaft 21 by 20 turns.

[0063] Similarly, when the cable with an outer diameter of 140 μm needs to be wound on the cable spool 21, the cable with an increased outer diameter wound on the cable spool 21 for 20 turns can have a large thickness value in the diameter direction of the cable spool 21, and the outer layer of the cable can not be blocked by the limiting portion 22, so that the outer layer of the cable is loose. Therefore, the length of the cable spool 21 can be kept unchanged, the thickness of the limiting portion 22 can be reduced, and the number of turns of the cable with an outer diameter of 140 μm wound on the length direction of the cable spool 21 can be increased, so that the number of turns of the cable wound on the diameter direction of the cable spool 21 is reduced, and the limiting portion 22 can block and bind the cable with an outer diameter of 140 μm wound on the cable spool 21 for 20 turns.

[0064] The size of the limiting portion 22 can be adjusted along the radial direction of the cable spool 21. For example, when the limiting portion 22 has a disc structure and the cable spool 21 has a cylindrical shaft structure, the limiting portion 22 is arranged at the end of the cable spool 21, and the center of the limiting portion 22 coincides with the rotation center axis of the cable spool 21. Therefore, the distance between the outer circular surface of the limiting portion 22 and the outer peripheral surface of the cable spool 21 is the maximum distance between the limiting portion 22 and the cable spool 21, and within the range of the maximum distance, the limiting portion 22 can block and bind the cable wound on the cable spool 21.

[0065] Specifically, taking the cable spool 21 as a cylindrical shaft structure as an example, the limiting portion 22 has an adjustable structure along the diameter direction of the cable spool 21. For example, when the limiting portion 22 can effectively block the cable, the number of turns of the cable with an outer diameter of 130 μm wound on the cable spool 21 can be 20 turns. When the cable with an outer diameter of 140 μm needs to be wound on the cable spool 21, the cable with an increased outer diameter wound on the cable spool 21 for 20 turns can have the outer layer of the cable not be blocked by the limiting portion 22, so that the outer layer of the cable can be loose. In view of this, the length of the cable spool 21 can be kept unchanged, the limiting portion 22 can be extended along the diameter direction of the cable spool 21, and the extended part of the limiting portion 22 can also block and bind the outer layer of the cable.

[0066] Alternatively, the limiting portion 22 can be kept unchanged, the length of the cable spool 21 can be increased, and the number of turns of the cable wound on the length direction of the cable spool 21 can be increased, so that the limiting portion 22 can block and bind the cable with an outer diameter of 140 μm wound on the cable spool 21 for 20 turns.

[0067] Similarly, for example, when considering material conservation or compatibility, it is necessary not only to wind a cable with an outer diameter of 125 μm onto the cable spool 21, but also to meet the requirement of winding 20 turns of cable. When 20 turns of cable with a reduced outer diameter are wound onto the cable spool 21, the maximum distance of the limiting part 22 in the diameter direction of the cable spool 21 may be greater than the thickness of the cable in the diameter direction of the cable spool 21, resulting in unnecessary material waste. Therefore, the length of the cable spool 21 can be kept constant, and the limiting part 22 can be reduced in the diameter direction of the cable spool, so that the limiting part 22 can just cover and restrain the outer layer of cable.

[0068] It should be noted that the cable spool 21 and the limiting part 22 can also be adjusted together. The principle of adjustment is the same as above, and will not be elaborated here.

[0069] like Figures 10 to 13 As shown, the limiting part 22 has a multi-layer structure in the thickness direction of the winding; wherein, adjacent layers are detachable or bendable.

[0070] In this embodiment, the multi-layer structure design of the limiting part 22 allows for flexible adjustment of the diameter of the cable reel 20, and adjacent layers are detachable or bendable. This design improves the versatility of the cable reel 20, making it suitable for different length coiling requirements, reducing the space occupied by coiling, improving the aesthetics and neatness of the cabling, and ensuring the feasibility of its installation by flexibly adjusting the diameter of the cable reel 20, reducing space occupation, and improving overall cabling efficiency and user experience.

[0071] Optionally, such as Figure 10 As shown, the adjacent layers of the limiting part 22 are connected by point connections and / or virtual connections. The limiting part 22 also includes a first structural member 225, a second structural member 226, and a third structural member 227. The first structural member 225 is located in the innermost layer, and one end of the cable spool 21 is connected to the inner wall of the first structural member 225 (the inner wall is the side wall of the first structural member 225 facing the cable spool 21). The connection between the one end of the cable spool 21 and the first structural member 225 can be achieved by welding, threaded connection, snap-fit, or other methods. The second structural member 226 is located in the middle, and the third structural member 227 is located in the outermost layer. The first structural member 225, the second structural member 226, and the third structural member 227 extend radially along the cable spool 21, and the first structural member 225, the second structural member 226, and the third structural member 227 are detachably connected to each other.

[0072] The outer end surface of the first structural member 225 and the inner end surface of the second structural member 226 are point connection or virtual connection, and the outer end surface of the second structural member 226 and the inner end surface of the third structural member 227 are point connection or virtual connection.

[0073] The outer end surface of the first structural member 225 and the inner end surface of the second structural member 226 are point connection or virtual connection, and the outer end surface of the second structural member 226 and the inner end surface of the third structural member 227 are point connection or virtual connection.

[0074] For example, the second structural member 226 and the third structural member 227 are annular structures, the second structural member 226 is nested on the outside of the first structural member 225, and the third structural member 227 is nested on the outside of the second structural member 226. The outer end surface of the first structural member 225 and the inner end surface of the second structural member 226 are provided with a plurality of spaced connection blocks, and the outer end surface of the second structural member 226 and the inner end surface of the third structural member 227 are provided with a plurality of spaced connection blocks. Alternatively, the first structural member 225, the second structural member 226, and the third structural member 227 are an integral structure, the outer end surface of the first structural member 225 and the inner end surface of the second structural member 226 are provided with a plurality of spaced grooves, and the adjacent grooves are the above-mentioned connection blocks. The outer end surface of the second structural member 226 and the inner end surface of the third structural member 227 are provided with a plurality of spaced grooves, and the adjacent grooves are the above-mentioned connection blocks. Therefore, the third structural member 227 can be separated from the second structural member 226, or the second structural member 226 can be separated from the first structural member 225 by cutting or cutting or breaking the connection blocks. Alternatively, the third structural member 227 can be connected to the second structural member 226, or the second structural member 226 can be connected to the first structural member 225 by bonding the connection blocks. Therefore, by adopting the above technical scheme, the length of the limiting portion 22 can be adjusted based on the actual installation environment to adapt to the change of the optical fiber on the cable reel 21.

[0075] For example, in order to facilitate the mutual separation of the first structural member 225, the second structural member 226, and the third structural member 227, the connection blocks with thinner thickness and softer material can be selected, or the connection blocks can be provided with grooves or holes to reduce the structural strength of the connection blocks, so that the installation personnel can break the connection blocks with less labor.

[0076] Alternatively, a non-through groove (e.g., a non-through notch) may be formed between the first structural member 225 and the second structural member 226, and a non-through groove may be formed between the second structural member 226 and the third structural member 227. Alternatively, a combination of non-through grooves and through grooves may be formed between the first structural member 225 and the second structural member 226 (e.g., alternating non-through notches and through notches in a ring position between the first structural member 225 and the second structural member 226), and a combination of non-through grooves and through grooves may be formed between the second structural member 226 and the third structural member 227, so that the installer can easily disconnect the first structural member 225 and the second structural member 226, and the second structural member 226 and the third structural member 227.

[0077] Alternatively, the first structural member 225 and the second structural member 226 can be bent relative to each other, and the second structural member 226 and the third structural member 227 can be bent relative to each other. The second structural member 226 and the third structural member 227 can be open-loop structures, strip structures, or block structures, etc., so that the length of the limiting portion 22 in the winding thickness direction can be changed by bending the second structural member 226, bending the third structural member 227, or bending both the second and third structural members 226.

[0078] like Figure 11 As shown, the limiting part 22 includes a movable arm 221, which is adjustable in the thickness direction of the winding.

[0079] In some embodiments, the movable arm 221 slides relative to the end of the cable shaft 21 along the thickness direction of the winding.

[0080] like Figure 11 As shown, the limiting part 22 also includes an end plate 222, which is disposed at the end of the cable shaft 21, and the movable arm 221 slides relative to the end plate 222 along the thickness direction of the winding.

[0081] In some embodiments, the surface of the end plate 222 is provided with a first groove, and one end of the movable arm 221 slides along the extension direction of the end plate 222 in the first groove.

[0083] In some embodiments, a damping block is provided in the first slide groove, and a damping groove is provided at one end of the movable arm.

The first sliding groove can be one or multiple, and in order to facilitate symmetry and achieve a better binding effect, the embodiment of the utility model preferably six, the six first sliding grooves extend along the radial direction of the cable shaft 21 and are arranged at intervals along the axial direction of the cable shaft 21. The movable arm 221 is arranged in cooperation with the first sliding groove, so that one end of the movable arm 221 slides in the radial direction of the first sliding groove, so as to change the distance between the other end of the movable arm 221 and the cable shaft 21, change the length of the limiting part, and then adapt to the total thickness change of the cable shaft 21 in the radial direction occupied by the different cable coils wound on the cable shaft 21, so as to achieve the effect of having a good binding effect on different types of cables.

[0085] The damping groove and the damping block are arranged in cooperation, so that there is a certain damping between the movable arm 221 and the end plate 222, that is, the movable arm 221 can be relatively fixed with the end plate 222 after moving a certain distance, so as to achieve the effect of binding the optical fiber.

[0086] In some embodiments, the surface of the movable arm 221 is provided with a second sliding groove, and the surface of the end plate 222 is provided with a sliding block, the sliding block is connected with the second sliding groove in sliding manner, and the second sliding groove extends along the length direction of the movable arm 221.

[0087] In some embodiments, the second sliding groove is provided with a damping groove, and the sliding block is a damping block.

[0088] In some embodiments, the sliding block is provided with a damping groove, and the second sliding groove is provided with a damping block.

[0089] The second sliding groove is arranged on the surface of the movable arm 221, and the sliding block is arranged on the surface of the end plate 222, and based on the sliding action of the second sliding groove and the sliding block, the distance between the other end of the movable arm 221 and the cable shaft 21 can also be changed, so as to change the length of the limiting part 22, and then adapt to the total thickness change of the cable shaft 21 in the radial direction occupied by the different cable coils wound on the cable shaft 21, so as to achieve the effect of having a good binding effect on different types of cables.

[0090] The damping groove and the damping block are arranged in cooperation, so that there is a certain damping between the movable arm 221 and the end plate 222, that is, the movable arm 221 can be relatively fixed with the end plate 222 after moving a certain distance, so as to achieve the effect of binding the optical fiber.

[0091] In some embodiments, the first sliding groove can also be arranged at the end of the cable shaft 21, and one end of the movable arm 221 slides in the thickness direction of the wire on the first sliding groove.

[0092] In some embodiments, the sliding block can also be arranged at the end of the cable shaft 21, and the sliding block is connected with the second sliding groove arranged on the movable arm 221 in sliding manner.

[0093] As shown in Figure 12 , Figure 13 , the limiting part 22 comprises a folding arm 224, which is a segmented folding structure, one end of which is connected with the cable shaft 21, and the distance between the other end of the folding arm 224 and the cable shaft 21 can be adjusted.

[0094] As shown in Figure 12 , in an exemplary embodiment, the folding arm 224 can be multiple, and when the multiple folding arms 224 are in the unfolded state (as shown in the left drawing of Figure 12 ), one end of each of the multiple folding arms 224 is connected with the cable shaft 21, and the other end of each of the multiple folding arms 224 extends radially along the cable shaft 21. Each folding arm 224 is a segmented folding structure, i.e. comprises multiple folding joints, which are connected in sequence. Therefore, by rotating each folding joint towards the cable shaft 21, the folding arm 224 can be transformed into the folded state (as shown in the right drawing of Figure 12 ). Therefore, by using the above scheme, the distance between the end of the folding arm 224 away from the cable shaft 21 and the cable shaft 21 can be changed to adapt to the change in the total thickness of the cable shaft 21 in the radial direction occupied by the different cables wound on the cable shaft 21, so as to achieve the effect of having a good binding effect on different types of cables.

Each folding arm 224 can be a polygonal telescopic structure, for example, a parallelogram telescopic structure. By pushing the end of the folding arm 224 away from the cable shaft 21 towards the cable shaft 21, the distance between the end of the folding arm 224 away from the cable shaft 21 and the cable shaft 21 can be shortened, so as to transform the folding arm 224 into the folded state (as shown in the right drawing of Figure 13 ). By pulling the end of the folding arm 224 away from the cable shaft 21 further away from the cable shaft 21, the distance between the end of the folding arm 224 away from the cable shaft 21 and the cable shaft 21 can be increased, so as to transform the folding arm 224 into the unfolded state. Therefore, by using the above scheme, the distance between the end of the folding arm 224 away from the cable shaft 21 and the cable shaft 21 can be changed to adapt to the change in the total thickness of the cable shaft 21 in the radial direction occupied by the different cables wound on the cable shaft 21, so as to achieve the effect of having a good binding effect on different types of cables.
