Description

Technical Field

[0001] This utility model belongs to the field of electronic device charging technology, and relates to a cable retractor module. Background Technology

[0002] For ease of use, existing data cables are generally very long when connecting over long distances. However, when not in use, the data cables easily become tangled, causing damage. Furthermore, untangling them for the next use is very troublesome. To achieve better storage, existing data cables use storage devices. One type of storage device requires manual winding of the cable, and when needed, the entire cable is pulled out, making storage very inconvenient.

[0003] Furthermore, during use, users sometimes pull out the data cable quickly, causing the cable reel to rotate rapidly. When the data cable is fully pulled out, the inertia of the cable reel and the sudden stop of the data cable can easily damage the cable reel and the data cable, especially the connection point between the end of the data cable and the take-up device, affecting the lifespan of the cable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pull-out module and its charging data cable for a pull-out device that is convenient, has an unlimited stretching length, can be pulled and stopped at will, and addresses the shortcomings of the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A cable reel module includes a cable winding assembly and a control assembly disposed within a housing. The cable winding assembly includes a cable reel and a cable reel shaft, and a counterweight to increase the rotational torque of the cable reel. The cable reel is rotatably connected to the housing via the cable reel shaft, and at least one counterweight is eccentrically mounted on the cable reel. The control assembly includes a swing element and a control element mounted within the housing. The swing element is rotatably connected to the housing, and the cable reel has a limiting port that cooperates with the swing element. The control element is slidably or rotatably connected to the housing to restrict the rotation or stop the swing element, so that the swing element cooperates with the limiting port to release or lock the rotation of the cable reel.

[0007] Furthermore, the control component also includes an assisting component, which provides a thrust to the swinging component to rotate toward the wire carrier when the swinging component moves out of the limiting port.

[0008] Furthermore, the assisting component is a first elastic element respectively disposed on both sides of the swinging component. After the swinging component moves out of the limiting port, it squeezes one of the first elastic elements, and the elastic force of the first elastic element generates a thrust on the swinging component to rotate towards the spool shaft.

[0009] Furthermore, the assisting component is a first magnetic component disposed on the swing component and a second magnetic component disposed on both sides of the swing component, wherein the first magnetic component and the second magnetic component attract or repel each other.

[0010] Furthermore, the winding assembly also includes a second elastic element installed between the housing and the wire carrier spool, providing a counter-torque after the wire carrier spool rotates.

[0011] Furthermore, the swing member is provided with a path groove, and the control member includes a limiting post and a slider. The slider is slidably connected in the housing, and the limiting post is engaged in the path groove. The rotation or stop of the swing member is limited by the shape of the path groove and the position of the limiting post in the path groove.

[0012] Furthermore, the path groove is a closed loop groove, and the path groove is provided with a first inflection point, a second inflection point, a third inflection point and a fourth inflection point for stopping the control component.

[0013] Furthermore, the path groove is closer to or farther from the axis of the coil shaft than the axis of rotation of the oscillating member.

[0014] Furthermore, the counterweight is arc-shaped or polygonal.

[0015] Furthermore, the wire carrier includes a rotating disk and a wire guard disk. The rotating disk is provided with a limiting groove for supporting the wire guard disk and the counterweight block. At least one limiting port is circumferentially disposed on the rotating disk. The wire guard disk is in contact with the second elastic member.

[0016] The following are the beneficial effects of implementing this utility model:

[0017] This utility model utilizes a cable winding assembly and a control assembly housed within a casing. The cable winding assembly includes a cable reel and a reel shaft, as well as a counterweight to increase the rotational torque of the cable reel. The cable reel is rotatably connected to the casing via the reel shaft. At least one of the counterweights is eccentrically mounted on the cable reel, thus providing some protection for the cable reel and the data cable when the user quickly pulls out the data cable. By reducing the rotational inertia of the cable reel, the tension at the connection point between the data cable and the take-up device is further alleviated, extending the service life of the take-up device and the data cable. The eccentric mounting of the counterweight on the cable reel makes the overall structure simpler and more compact, saving manufacturing costs. It allows for the stretching of the data cable to any length, stopping as needed, and the winding is completed automatically, making it very convenient and practical. Attached Figure Description

[0031] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] A component is referred to as being "fixed to" or "set on" another component, and it may be located directly or indirectly on that other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to that other component.

[0033] The terms "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the accompanying drawings and are used only for ease of description, and should not be construed as limiting the technical solution. The terms "first," "second," etc., are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "Multiple" means two or more, unless otherwise explicitly defined.

[0034] Please see Figures 1 to 6 The first embodiment of this utility model provides a cable reel module, which includes a cable winding assembly 2 and a control assembly 3 disposed within a housing 1. The cable winding assembly 2 includes a cable reel 21 and a cable reel shaft 22, as well as a counterweight block 23 that increases the rotational torque of the cable reel 21. The cable reel 21 is rotatably connected to the housing 1 via the cable reel shaft 22. At least one counterweight block 23 is eccentrically mounted on the cable reel 21. The control assembly 3 includes a swing member 31 and a control member 32 disposed within the housing 1. The swing member 31 is rotatably connected to the housing 1. The cable reel 21 is provided with a limiting port 33 that cooperates with the swing member 31. The control member 32 is slidably or rotatably connected to the housing 1 to restrict the rotation or stop the swing member 31, so that the swing member 31 cooperates with the limiting port 33 to release or lock the rotation of the cable reel 21.

[0035] This application adds a counterweight 23 to the cable carrier 21 to increase its rotational torque. The cable carrier 21 is rotatably connected to the housing 1 via a cable reel shaft 22. At least one counterweight 23 is eccentrically mounted on the cable carrier 21. When the data cable is pulled out, causing the cable carrier 21 to rotate, the counterweight 23 will rotate along with the cable carrier 21. Because the counterweight 23 is eccentrically mounted on the cable carrier 21, the rotating counterweight 23 will generate centrifugal force, which is used to disperse the rotational torque and inertia of the cable carrier 21, especially when the cable carrier 21 is rotating to the end. The eccentric counterweight 23 can disperse the rotational inertia of the cable tray 21, giving the cable tray 21 a certain resistance when rotating, slowing down the rotation speed, and thus providing a certain degree of protection for the cable tray 21 and the data cable when the user quickly pulls out the data cable. By reducing the rotational inertia of the cable tray 21, the tension at the connection point between the data cable and the cable retractor is further reduced, extending the service life of the cable retractor and the data cable. The eccentric installation of the counterweight 23 on the cable tray 21 makes the overall structure simpler and more compact, saving manufacturing costs.

[0036] Multiple counterweights 23 can be eccentrically set on the cable carrier 21 to disperse the inertial force of the cable carrier 21 rotation in multiple directions, further reducing the speed of the cable carrier 21 when it rotates to the end, reducing damage to the data cable, and extending its service life.

[0037] The counterweight 23 can be installed on the cable tray 21 via a snap-fit ​​connection, facilitating installation and improving assembly efficiency. Alternatively, the counterweight 23 can be glued to the cable tray 21 for a tighter connection, reducing gaps, improving appearance, and minimizing dust contamination of the data cable. Finally, the counterweight 23 can be installed on the cable tray 21 using screws and threaded holes, facilitating replacement and ensuring a more secure connection.

[0038] This application utilizes a swing member 31 and a control member 32 installed in the housing 1. The swing member 31 is rotatably connected to the housing 1, and the cable tray 21 is provided with a limiting port 33 that cooperates with the swing member 31. The control member 32 is slidably or rotatably connected to the housing 1, restricting or stopping the rotation of the swing member 31, so that the swing member 31 cooperates with the limiting port 33 to release or lock the rotation of the cable tray 21. When the control member 32 releases the restriction on the swing member 31, the swing member 31 can rotate. When the user pulls the data cable, the data cable will drive the cable tray 21 to rotate. The rotating cable tray 21 will deflect the swing member 31, causing the cable tray 21 to drive the swing member 31 to deflect. During the deflection process, the top of the swing member 31 will separate from the limiting port 33, allowing the user to pull out the data cable at will.

[0039] To fix the length of the pulled-out data cable, a spring can be installed in the housing 1. Then, continue pulling the data cable to rotate the cable carrier 21. When the limiting port 33 on the cable carrier 21 passes the top of the swing member 31, the top of the swing member 31 will fall into the limiting port 33. Then, the rotation of the swing member 31 is stopped by the control member 32, so that the top of the swing member 31 cannot separate from the limiting port 33. Thus, the rotation of the cable carrier 21 is locked by the cooperation between the top of the swing member 31 and the limiting port 33, which makes it easier to control the length of the pulled-out data cable. When using it, it is not necessary to pull out the entire data cable at once, making the operation more flexible and applicable to more usage scenarios. When storing, simply release the rotation of the cable carrier 21, and then rotate the cable carrier 21 in the opposite direction to let the data cable rewrap on the cable carrier 21, making the operation more labor-saving and efficient.

[0040] The swing member 31 can be rotated or stopped by the control member 32. When the length of the pulled-out data cable is to be fixed, the user can use the control member 32 to manipulate the swing member 31 to rotate in the opposite direction, so that the top of the swing member 31 moves into the limit port 33. Then the control member 32 is locked, so that the swing member 31 cannot rotate. The swing member 31 and the limit port 33 cooperate to lock the rotation of the cable tray 21, so that the data cable can no longer be pulled out of the housing 1 through the cable tray 21. As a result, the whole structure is more compact and saves manufacturing costs.

[0041] Please see Figures 2 to 5 In some embodiments, the control component 3 further includes an assist component 34, which provides a thrust to the swing component 31 to rotate toward the wire reel 21 when the swing component 31 moves out of the limit port 33.

[0042] This application also includes an assistive component 34 in the control component 3. When the swinging component 31 moves out of the limiting port 33, the assistive component 34 provides a thrust to the swinging component 31 to rotate towards the cable reel 21. By utilizing the thrust provided by the assistive component 34, the swinging component 31 is pushed into the limiting port 33 each time the limiting port 33 of the cable reel 21 passes by the assistive component 34. Since the rotation of the swinging component 31 is not yet restricted by the control component 32 at this time, as the user continues to pull the data cable, the cable reel 21 continues to rotate, causing the cable reel 21 to overcome the thrust provided by the assistive component 34 and rotate the swinging component 31. The top of the swinging component 31 separates from the limiting port 33, and the user can continue to pull out the data cable. By utilizing the resistance of the top of the swinging component 31 entering the limiting port 33 each time, the inertia of the cable reel 21 during rotation can be further reduced, thereby reducing the rotational speed of the cable reel 21 when pulling out the data cable, further protecting the data cable during pull-out and extending its service life.

[0043] When you want to fix the length of the pulled-out data cable, you only need to let the top of the swing member 31 enter the limit port 33, and then restrict the rotation of the swing member 31 by the control member 32. The rotation of the cable tray 21 can be locked by the cooperation between the swing member 31 and the limit port 33, which makes it easy to control the length of the pulled-out data cable and is suitable for more usage scenarios.

[0044] Please see Figures 2 to 5 In some embodiments, the assisting member 34 is a first elastic member respectively disposed on both sides of the swing member 31. After the swing member 31 moves out of the limiting port 33, it squeezes one of the first elastic members. The elastic force of the first elastic member generates a thrust on the swing member 31 to rotate towards the spool shaft 22.

[0045] After the swing member 31 moves out of the limiting port 33, it squeezes one of the first elastic members. The elastic force of the first elastic member generates a thrust on the swing member 31 to rotate towards the coil shaft 22. The first elastic member can be a spring or a sheet spring, which saves manufacturing costs.

[0046] Alternatively, a rubber block made of rubber material can be used. The rubber itself generates a pushing force on the oscillating component 31 upon contact with it. The rubber block can have a certain arc shape, which further generates the pushing force through its elasticity. The rubber block also provides insulation, preventing leakage in the reel and reducing its overall weight, making it easier to operate and store. Depending on the actual application, the rubber block can be designed as a hollow structure or in different shapes to facilitate installation, save internal space, and make the reel's structure more compact and lightweight.

[0047] Please see Figures 8 to 10 In some embodiments, the assisting element 34 is a first magnetic element disposed on the swinging element 31 and a second magnetic element disposed on both sides of the swinging element 31, wherein the first magnetic element and the second magnetic element attract or repel each other.

[0048] This application utilizes an assistive component 34 consisting of a first magnetic component mounted on the swing component 31 and second magnetic components mounted on both sides of the swing component 31. The first and second magnetic components attract or repel each other. When the first and second magnetic components repel each other on the same side, they can be positioned on the front sides of the swing component 31, that is, between the rotation axis of the swing component 31 and the rotation axis of the cable carrier 21. The rotating cable carrier 21 overcomes the magnetic repulsion between the first and second magnetic components, causing the swing component 31 to rotate. When the magnetic repulsion between the first and second magnetic components passes through the limiting port 33, it pushes the swing component 31 back into the limiting port 33, thereby slowing down the rotation speed of the cable carrier 21, reducing the inertia of the cable carrier 21, and providing a certain degree of protection for the data cable and the take-up device. It further saves space occupied by the assist component 34, making its overall rhythm more compact, and also avoids wear caused by contact between them, further extending its service life, making it easier to install, reducing the noise generated when the swing component 31 squeezes the assist component 34, and making the use process more comfortable and smooth.

[0049] When the first and second magnetic components attract each other on the same side, they can be positioned on the rear sides of the swing member 31, that is, further away from the rotation axis of the wire carrier 21 than the rotation axis of the swing member 31. When the wire carrier 21 moves the swing member 31 counterclockwise and separates it from the limiting port 33, the rear left side of the swing member 31 will sink, causing the left side of the first magnetic component to move away from the second magnetic component, while the rear right side of the swing member 31 will rise, causing the right side of the first magnetic component to move closer to the second magnetic component. The magnetic force of attraction will cause the left side of the first magnetic component to move closer to the second magnetic component, and at the same time, the right side of the first magnetic component to move closer to the right side of the second magnetic component. The resulting magnetic force will exert a clockwise rotational force on the rear of the swing member 31, causing the limiting port 33 to push the top of the swing member 31 into the limiting port 33 as it passes the swing member 31. By generating magnetic attraction on both sides, the thrust on the swinging component 31 to rotate toward the cable carrier 21 can be increased, further slowing down the rotation speed of the cable carrier 21, reducing the inertia of the cable carrier 21, and playing a certain protective role for the data cable and the take-up device.

[0050] Please see Figure 5 and Figure 7 In some embodiments, the winding assembly 2 further includes a second elastic element 24 installed between the housing 1 and the wire reel 21 to provide a reverse torque after the wire reel 21 rotates.

[0051] This application utilizes a second elastic element 24 installed between the housing 1 and the cable reel 21. The second elastic element 24 can be a torsion spring, a spring, or a retaining ring. When the second elastic element 24 is a torsion spring, the more rotations the cable reel 21 makes, the greater the opposing torque provided by the second elastic element 24. This provides good rotational resistance to the cable reel 21 when the data cable is fully pulled, reducing the rotational inertia of the cable reel 21. When the second elastic element 24 is a retaining ring, when the angle of rotation of the cable reel 21 is too large, the retaining ring will move from one retaining slot to another to release the spring force of the retaining ring. This ensures that the retaining ring can only drive the cable reel 21 to rotate in the opposite direction by a certain angle for cable reeling, thus making it suitable for more usage environments and making it easier for the pulled-out data cable length to stop at the appropriate position.

[0052] When the cable carrier 21 rotates counterclockwise to release the cable, the second elastic element 24 stores clockwise torque in the cable carrier 21. By storing the opposite torque, the resistance to the cable carrier 21 rotating when pulling the cable can also be increased, further slowing down the rotation speed of the cable carrier 21, reducing the inertia of the cable carrier 21, and playing a certain role in protecting the data cable and the take-up device.

[0053] The second elastic element 24 generates a reverse torque. After the cable tray 21 rotates forward to release the cable, the user can limit the rotation angle of the swing element 31 through the control element 32. This prevents the top of the swing element 31 from rotating further after it enters the limiting port 33. After the user releases the cable after pulling out the appropriate length, the torque generated by the second elastic element 24 causes the cable tray 21 to rotate in the opposite direction to retract the cable. When the top of the swing element 31 enters the limiting port 33, the swing element 31 can no longer rotate, thus locking the rotation of the cable tray 21 and allowing the pulled-out cable to stay conveniently outside the housing 1.

[0054] The user can then release the control unit 32 from restricting the rotation angle of the swinging member 3, allowing the cable tray 21 to rotate by moving the swinging member 31, so that the second elastic member 24 can continue to drive the cable tray 21 to rotate in the opposite direction. The cable tray 21, which continues to rotate in the opposite direction, will collect all the data cables, making it easier to quickly collect the data cables and simplifying the operation.

[0055] Please see Figures 3 to 5 In some embodiments, the swing member 31 is provided with a path groove 35, and the control member 32 includes a limiting post 321 and a slider 322. The slider 322 is slidably connected in the housing 1, and the limiting post 321 is engaged in the path groove 35. The rotation or stop of the swing member 31 is limited by the shape of the path groove 35 and the position of the limiting post 321 in the path groove 35.

[0056] This application provides a path groove 35 on the swing member 31. The control member 32 includes a limiting post 321 and a slider 322. The slider 322 is slidably connected in the housing 1, and the limiting post 321 is engaged in the path groove 35. The shape of the path groove 35 and the position of the limiting post 321 in the path groove 35 limit the rotation or stop of the swing member 31. The path groove 35 can be provided with multiple fixed corners for stopping the limiting post 321, and the rest are non-obstructive slides. The fixed corners are nodes for data cable retraction and extension, and the positional relationship between the swing member 31 and the cable tray 21 is changed at the nodes. Through the cooperation of the path groove 35 and the limiting post 321, the user no longer needs to operate the control member 32. When the data cable is pulled out, it causes the cable tray 21 to rotate clockwise. The cable tray 21 pushes aside the swing member 31, and the limiting post 321 moves from one fixed corner to another. When the user stops pulling the data cable, the second elastic member 24 drives the cable tray 21 to rotate counterclockwise until the limiting port 33 moves to the position of the swing member 31. Under the action of the assist member 34, the swing member 31 rotates into the limiting port 33. During the rotation of the swing member 31, the limiting post 321 enters the next fixed corner through the path groove 35, limiting the rotation angle of the swing member 31. The rotation of the cable tray 21 is locked by the cooperation between the top of the swing member 31 and the limiting port 33. This makes the operation more automated and convenient, improves the efficiency of locking the rotation of the cable tray 21, and allows for the setting of different numbers of fixed corners according to different usage environments. Each additional fixed corner provides another way to lock the cable tray 21 to release the data cable length, thus expanding the scope of use and making the operation more diversified.

[0057] Please see Figure 4 In some embodiments, the path groove 35 is a closed loop groove, and the path groove 35 is provided with a first inflection point 351, a second inflection point 352, a third inflection point 353 and a fourth inflection point 354 for stopping the control member 32.

[0058] This application provides a path groove 35 with a first inflection point 351, a second inflection point 352, a third inflection point 353, and a fourth inflection point 354 for stopping the control member 32. The first inflection point 351, the second inflection point 352, and the fourth inflection point 354 correspond to the non-coupling state when the top of the swing member 31 rotates to the limiting opening 33 of the cable tray 21, and the third inflection point 353 corresponds to the coupling state when the swing member 31 rotates to the limiting opening 33 of the cable tray 21. Other non-obstruction slides smoothly transition between the inflection points to form a closed loop groove. For smooth sliding, the four fixed corner points are the basis for determining the path groove 35. The width, extension direction, shape, etc. of the path groove 35 are determined in conjunction with the swing process of the swing member 31, and are not limited here. That is, the shape of the path groove 35 can be various and is not limited to the shape of this embodiment.

[0059] Please see Figures 3 to 5In some embodiments, the cooperation process between the swing member 31, the limiting port 33, the limiting post 321, and the assist member 34 is as follows:

[0060] The data cable is completely housed inside the housing 1. The limiting post 321 slides in the path groove 35 of the swing member 31 to the position of the first inflection point 351. At this time, the swing member 31 and the limiting port 33 do not cooperate (in this embodiment, cooperation means that the front end of the swing member 31 is inserted into the limiting port 33 and abuts, the same below). The cable tray 21 can rotate counterclockwise indefinitely. This position is the starting position. At this time, the assist member 34 always provides the swing member 31 with the thrust to rotate the cable tray 21.

[0061] When the data cable is stretched outward, the limiting port 33 rotates clockwise with the cable carrier 21, and the assist component 34 drives the swing component 31 to rotate counterclockwise. The limiting post 321 slides in the path groove 35 to the position of the second inflection point 352 (the sliding trajectory is from the position of the first inflection point 351 to the position of the second inflection point 352). At this time, the limiting port 33 and the swing component 31 are still in a non-cooperative separated state (the front end of the swing component 31 only abuts against the edge of the limiting port 33). The cable carrier 21 can continue to rotate outward to stretch the length of the cable without stopping, and stop after stretching to the appropriate length.

[0062] When the data cable is stretched to the appropriate length and the stretching stops, the second elastic element 24, which stores force in the housing 1, will drive the cable tray 21 to rotate, thereby driving the limiting port 33 to rotate. When the assisting element 34 drives the swinging element 31 to rotate to the position of the second inflection point 352, the front end of the swinging element 31 begins to insert into the limiting port 33 to cooperate. The limiting port 33 will rotate in the opposite direction (i.e., counterclockwise) so that the swinging element 31 rotates clockwise. At this time, the limiting post 321 moves from the path groove 35 at the position of the second inflection point 352 to the position of the third inflection point 353. The swinging element 31 is blocked by the limiting post 321 and can no longer rotate (clockwise). At the same time, it cooperates with the limiting port 33 to lock the cable tray 21, so that the data cable is stationary after being stretched to the required appropriate length.

[0063] Pull the data cable again, and the limit port 33 will rotate clockwise again with the cable tray 21, causing the swing member 31 to rotate counterclockwise. The front end of the swing member 31 will disengage from the limit port 33. At the same time, the limit post 321 will slide along the path groove 35 from the position of the third inflection point 353 to the position of the fourth inflection point 354 and stop sliding. At this time, the swing member 31 will no longer rotate, and the limit port 33 can continue to rotate outward to stretch the length of the cable without stopping.

[0064] When the data cable stops stretching and needs to rotate in the opposite direction (the limiting port 33 rotates counterclockwise), the assist component 34 provides a push to the swing component 31, causing the swing component 31 to have an initial clockwise rotation state. The limiting post 321 moves from the path groove 35 at the fourth inflection point 354 to the position of the first inflection point 351. At this time, the limiting port 33 and the swing component 31 are in a non-cooperative state, and the cable tray 21 can continue to rotate to store the data cable until it is fully stored. The whole process is more convenient for users to operate, and can stop the data cable in a suitable position, improving the efficiency of storing or releasing the data cable.

[0065] Please see Figure 4 and Figure 9 In some embodiments, the path groove 35 is closer to or farther from the axis of the coil shaft 22 than the axis of rotation of the oscillating member 31.

[0066] This application places the path groove 35 closer to the axis of the spool shaft 22 than the rotation axis of the swing member 31. This allows the swing angle of the swing member 31 to be larger, reducing the jamming when the swing member 31 engages with the limiting port 33, thus making the entire take-up device operate more smoothly.

[0067] This application places the path groove 35 away from the axis of rotation of the oscillating member 31, away from the axis of the spool shaft 22. This results in a smaller oscillation amplitude of the oscillating member 31, making the entire take-up device more compact and saving storage space.

[0068] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the counterweight 23 is arc-shaped or polygonal.

[0069] This application uses an arc-shaped counterweight 23, which can better fit the shape of the cable reel 21 and the cable shaft 22. When the data cable is wound around the counterweight 23 and the cable reel 21, it can be more compact, preventing the data cable from getting tangled. It can also save space occupied by the counterweight 23, making the structure of the cable reel more compact and saving storage space.

[0070] The present application uses a polygonal counterweight 23, which is easy to manufacture and install. The polygonal counterweight 23 can be installed on both sides of the cable tray 21, and can be connected more tightly with the cable tray 21.

[0071] Please see Figure 3 , Figure 5 , Figure 6 and Figure 10In some embodiments, the wire carrier 21 includes a rotating disk 211 and a wire guard 212. The rotating disk 211 is provided with a limiting groove 213 for supporting the wire guard 212 and the counterweight 23. At least one limiting port 33 is circumferentially disposed on the rotating disk 211. The wire guard 212 is in contact with the second elastic member 24.

[0072] This application features a limiting groove 213 on the rotating disk 211 to support the cable guard 212 and the counterweight 23. The limiting groove 213 allows for a tighter connection between the cable guard 212 and the counterweight 23 and the rotating disk 211, reducing the wobbling of the counterweight 23 during rotation, improving the stability of the take-up device during use, and extending its service life. It also facilitates the positioning and replacement of the counterweight 23 and the cable guard 212.

[0073] This application uses at least one limiting port 33 circumferentially arranged on the rotating disk 211. The more limiting ports 33 are provided, the faster the oscillating member 31 locks onto the rotating disk 211, thereby improving the sensitivity of the take-up device. Furthermore, the more limiting ports 33 are provided, the smaller the angle of reverse rotation of the rotating disk 211 under the action of the second elastic member 24, resulting in a shorter length of data cable retraction by the rotating disk 211, thus improving the accuracy of the data cable length being pulled out.

[0074] This application ensures that the second elastic element 24 contacts the line guard 212, so that the second elastic element 24 will only wear the line guard 212 when it is storing power, thereby reducing the cost of replacing parts and extending the service life of the entire take-up device.
