Description

Technical Field

[0001] This utility model relates to the field of data cable storage technology, specifically a data cable storage device. Background Technology

[0002] Data cables, as common data transfer tools, are used to connect two electronic devices for data transfer or to connect electronic devices to a power source for charging. However, after use, data cables may be discarded. Due to their length, when there are many data cables, they are easily bent and tangled, making them difficult to store properly.

[0003] For example, document CN220492362U proposes a magnetic absorption and storage device for data cables. The specification states in paragraph [] that "both ends of the data cable are placed on two openings, and the connectors at both ends of the data cable are located on the outside of the storage box on both sides. Then, the box lid is closed, so that opening two contacts opening one to form a through hole. Then, the handle is turned, which drives the rotating rod, lower circular plate, circular connecting block, and arc-shaped plate to rotate inside the storage box, allowing the data cable to be wound up and stored until the connectors at both ends of the data cable contact the two grooves. Then, the connectors of the data cable are placed into the slots." This method causes both ends of the data cable to retract simultaneously during use; in other words, the data cable always extends or shortens at the same time, and the length of one end of the data cable cannot be adjusted individually, which is inconvenient for the use of the data cable. Therefore, we propose a data cable storage device. Utility Model Content

[0004] This utility model provides a data cable storage device, which not only stores the data cable, but also allows for independent length adjustment at both ends of the data cable, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A data cable storage device includes a shell with winding cavities at both ends, each winding cavity having a pull-out opening on its side, a mounting hole at the center of the shell, and turntables movably disposed inside both ends of the shell. Limiting protrusions are provided on the sides of the turntables, and the limiting protrusions are connected to the sides of the turntables via an elastic structure. Limiting teeth corresponding to the limiting protrusions are provided on the inner edges of both ends of the shell. The limiting protrusions are elastically positioned within the limiting teeth under the action of the elastic structure. A support shaft is coaxially disposed at the center of each turntable, and a data cable is disposed on the support shaft. The data cables are respectively placed in the pull-out openings. The ends of the support shafts furthest from the turntables are rotatably installed in the mounting holes. A sliding power supply mechanism is provided at the ends of the two support shafts that are close to each other, and the two data cables are connected through the sliding power supply mechanism.

[0006] Preferably, levers are provided on the surfaces of the two turntables that are far apart from each other.

[0007] Preferably, the number of limiting protrusions on the side of the turntable is at least one, and the elastic structure includes a cylindrical hole opened on the side of the turntable and extending toward its center. Each cylindrical hole is provided with a spring, and the limiting protrusion is movably placed in the cylindrical hole. Under the action of the spring, the end of the limiting protrusion makes elastic contact with the limiting tooth mark.

[0008] Preferably, one end of the data cable is fixed on the support shaft, and the data cable is connected to the sliding contact power supply mechanism from inside the support shaft.

[0009] Preferably, the sliding power supply mechanism includes two coaxially arranged annular electrodes, each annular electrode having a conductive spring on its surface. The annular electrode is mounted on the end face of one support shaft, while the conductive spring is mounted on the end face of the other support shaft, and the conductive spring is in elastic contact with the annular electrode.

[0010] Preferably, both data cables have plugs at their ends, and two placement slots are provided on the side of the housing. The placement slots are located on one side of the two pull-out openings. When the data cables are completely wrapped around the support shaft, the plugs are placed in the placement slots.

[0011] Compared with existing technologies, in this invention, data cables are wound around the support shafts at both ends of the outer casing, so the length of either data cable can be freely adjusted. Furthermore, the data cables will not extend or retract freely during length adjustment because the edge of the turntable has limiting protrusions that elastically contact the limiting teeth on the end of the outer casing. This creates a damping force on the edge of the turntable, allowing it to rotate only under significant pulling force, thus enabling the data cables to be pulled out and positioned.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 6 This utility model provides a technical solution: a data cable storage device, including a housing 6, with winding cavities 11 at both ends of the housing 6, the two winding cavities 11 being coaxially arranged, and a mounting hole 10 at the center of the housing 6, such as... Figure 3 As shown, the mounting hole 10 and the winding cavity 11 are also coaxial. Turntables 1 are movably mounted inside both ends of the outer casing 6. Limiting protrusions 7 are provided on the sides of the turntables 1, and the limiting protrusions 7 are connected to the sides of the turntables 1 via an elastic structure, such as... Figure 3 and Figure 4 As shown, the elastic structure includes cylindrical holes 9 opened on the side of the turntable 1 and extending toward its center. Each cylindrical hole 9 is provided with a spring, and the limiting protrusion 7 is movably placed in the cylindrical hole 9.

[0022] Both ends of the outer casing 6 have corresponding limiting teeth 8 at their inner edges. The limiting protrusions 7 are elastically positioned within the limiting teeth 8 under the action of the elastic structure. That is, under the action of the spring, the ends of the limiting protrusions 7 elastically contact the limiting teeth 8. In actual use, there must be at least one limiting protrusion 7 on the side of the turntable 1, specifically two, three, or more. When there are at least two limiting protrusions 7, they need to be symmetrically distributed so that multiple limiting protrusions 7 can elastically contact the limiting teeth 8 together. Therefore, when the turntable 1 is rotated, the turntable 1 will generate a certain damping force due to the elastic contact of the limiting protrusions 7 with the limiting teeth 8. Figure 1 and Figure 2As shown, in order to facilitate the turntable 1, levers 3 are provided on the surfaces of the two turntables 1 that are far apart from each other. The user can hold the levers 3 to rotate the turntable 1. When the rotational force is greater than the contact force between the limiting protrusion 7 and the limiting tooth mark 8, the turntable 1 can rotate. When the rotational force is less than the contact force between the limiting protrusion 7 and the limiting tooth mark 8, the turntable 1 will remain stationary.

[0023] Furthermore, to ensure stable support for the turntable 1, a support shaft 12 is coaxially positioned at the center of the turntable 1. Data cables 2 are mounted on the support shaft 12, and each winding cavity 11 has a pull-out opening 5 on its side. The data cables 2 are placed within the pull-out openings 5, with one end of each data cable 2 fixed to the support shaft 12. Next, the end of the support shaft 12 furthest from the turntable 1 is rotatably installed in the mounting hole 10. The support shaft 12 and the end of the mounting hole 10 are connected by bearings. During assembly, the bearing is first installed at the end of the support shaft 12, and then pressed into the end of the mounting hole 10. At this point, the support shaft 12 is firmly fixed inside the outer casing 6, and the turntable 1 is also installed in the preset position within the end of the outer casing 6. When the turntable 1 is rotated, the data cables 2 will wind around the support shaft 12. When the data cables 2 are pulled, if the pulling force is greater than the contact force between the limiting protrusion 7 and the limiting tooth mark 8, the data cables 2 can be pulled out.

[0024] It should be noted that both data cables 2 have plugs at their ends. These plugs should be compatible with the charging devices corresponding to the data cables 2, such as USB plugs, Type-C plugs, etc. Furthermore, two placement slots 4 are located on the side of the outer casing 6, respectively located on one side of the two pull-out openings 5. Figure 4 As shown, when the data cable 2 is completely wrapped around the support shaft 12, the plugs are placed in the placement slots 4. This prevents the plugs from being loosely secured and affecting the appearance. In use, the plugs are simply pulled out of the placement slots 4 to remove the data cable 2. It should be noted that the placement slots 4 are specifically U-shaped, their size and dimensions matching the corresponding plugs. A notch is provided on the side of the placement slot 4 near the pull-out opening (e.g.,...). Figure 1 (As indicated by the middle arrow A), when using it, the plug is simply snapped or clipped into the placement slot 4, and then the data cable is placed in the notch; of course, the placement slot 4 can also be in other forms, as long as it can fix the plug.

[0025] Based on the above embodiments, the two data lines 2 are respectively wound around the two support shafts 12, so each data line 2 can be pulled out individually. However, the two support shafts 12 are independent of each other. Therefore, in order to make the two data lines 2 conduct, a sliding contact power supply mechanism is provided at the end of the two support shafts 12 that are close to each other, and the two data lines 2 are conducted through the sliding contact power supply mechanism.

[0026] like Figure 4 , Figure 5 and Figure 6As shown, the sliding contact power supply mechanism includes two coaxially arranged annular electrodes 14, each with a conductive spring piece 13 on its surface. During installation, the annular electrodes 14 are mounted on the end face of one support shaft 12, while the conductive spring piece 13 is mounted on the end face of the other support shaft 12, and the conductive spring piece 13 is in elastic contact with the annular electrodes 14; when the support shaft 12 is assembled into the mounting hole 10, the conductive spring piece 13 can then elastically contact the surface of the annular electrodes 14.

[0027] like Figure 4 As shown, data line 2 is connected to the sliding contact power supply mechanism from inside the support shaft 12. That is, the positive and negative wire cores inside data line 2 are connected to the conductive spring 13 and the ring electrode 14 from inside the support shaft 12, respectively. This allows the two data lines 2 to conduct, so that the two data lines 2 can conduct to each other no matter which one is pulled out.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
