[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0030] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0031] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0032] The box of the retractable data cable contains a spring. When it is pulled out to a certain length, the spring is tightened by force. Once the use is completed, the spring in the box will automatically restore its deformation, and the data cable will also shrink under the action of elastic force, so the data cable will be rolled up. However, due to different usage scenarios, users need different lengths of data cables. The relevant technology is difficult to meet the gear adjustment of data cables of longer lengths and meet the needs of more users.

[0033] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a cable reel 1 for a retractable data cable. Figure 2 The longitudinal section of the reel is a section parallel to the symmetry axis Z of the reel. It is not necessary to require the reel to be an absolutely axially symmetrical figure. The reel can generally be regarded as an axially symmetrical figure. The Z axis can be regarded as Figure 1The direction from top to bottom in the orientation shown. The cable reel 1 in the embodiment of the utility model comprises: a housing 11, a wheel core 14 and an adjustment assembly 15. Among them, the housing 11 has an accommodating chamber 12 inside, and the housing 11 is provided with an opening 13 for the data cable 2 to pass through, and the opening 13 is connected to the accommodating chamber 12; the wheel core 14 is arranged in the accommodating chamber 12, and is used for winding the data cable 2, and the wheel core 14 can rotate with the extension and contraction of the data cable 2; it can be understood that the data cable 2 is wound on the wheel core 14, and is arranged together with the wheel core 14 in the accommodating chamber 12 in the housing 11, and the data cable 2 extends out of the housing 11 through the opening 13. When the data cable 2 is extended and contracted, the movement of the data cable 2 exerts a force on the wheel core 14, which will drive the wheel core 14 to rotate together. Among them, the adjustment assembly 15 is used to adjust the rotation angle of the 14, and the minimum angle of the rotation angle is less than 360 degrees. It can be understood that the state in which the data line 2 extends out of the opening 13 with the shortest length is defined as the initial state, and the corresponding wheel core rotation angle in the initial state is 0 degrees. Then, the longer the data line 2 is outside the opening 13, the greater the rotation angle of the wheel core 14. The rotation angle of the wheel core 14 can be adjusted by the adjustment component 15, thereby correspondingly adjusting the length of the data line outside the opening 13 (hereinafter referred to as the data line length). Among them, the minimum rotation angle of the wheel core 14 is less than 360 degrees, that is, the adjustment of one gear can be achieved within one rotation of the wheel core 14.

[0034] The cable reel of the utility model embodiment adjusts the rotation angle of the wheel core so that the minimum rotation angle of the wheel core is less than 360 degrees, which is equivalent to the related technology that the wheel core rotates more than one circle to achieve one gear adjustment. The rotation angle adjustment range of the wheel core of the utility model is relatively small, and one gear adjustment is achieved within one circle of the wheel core, thereby achieving approximately stepless adjustment of the extended length of the data cable, thereby meeting the user's various usage requirements for the extended length of the data cable.

[0035] In some embodiments, Figure 3 As shown, the adjustment assembly 15 includes: a gear member 151 and a clamping member 152. The gear member 151 is connected to the wheel core 14 to rotate with the wheel core 14. The gear member 151 is provided with a plurality of gear teeth 1511 along the circumferential direction, and a groove 1512 is formed between adjacent gear teeth. It can be understood that the gear member is fixedly connected to the wheel core 14 and rotates with the wheel core 14. Further, the gear member 151 is provided with a plurality of gear teeth 1511 along the circumferential direction, and one gear tooth corresponds to one gear position. In some embodiments, it is necessary to provide a number m of gear teeth greater than or equal to 10 on the gear member 151, that is, m≥10.

[0036] In some embodiments, the data line is wound around the wheel core 14 as follows: Fig. 9 As shown, combined Figure 1As shown, the two ends of the reel housing are open. It can be understood that when the user pulls the data cable outward from the two openings, the wire is pulled outward from the two openings due to the rotation of the wheel core. The length of the wire pulled out is twice the circumference of the wheel core after the wheel core rotates one circle. That is, when the wheel core 14 rotates the first circle, the wire pulled out is the wire wound around the first and second circles (counted from the outside to the inside) on the outermost side of the wheel core, and the total length of the pulled out wire is about 35cm; when the wheel core rotates the second circle, the wire pulled out is wound around the third and fourth circles (counted from the outside to the inside), and the further pulled out wire length is about 25cm in total, and the total pulled out wire length is 60cm... and so on.

[0037] Then, if 10 gear teeth are set, that is, the wheel core has 10 gears in one rotation, when the wire pulling length is from 0-35cm stage (the first circle of the wheel core rotation), each gear pulls out 3.5cm, and when the wire pulling length is from 35-60cm stage (the second circle of the wheel core rotation), each gear pulls out 2.5cm... At this time, in the process of changing between two adjacent gears, the length change of the data cable will become smaller and smaller, which can be approximately regarded as stepless adjustment, and various lengths required by users can be adaptively adjusted.

[0038] In some embodiments, the number of teeth of the gear can also be adjusted by the following formula. Wherein, the number of teeth = (L1+L2) / Pmax, L1 is the length of the data line in the outermost circle of the wheel core, L2 is the length of the data line in the second circle of the wheel core from the outside to the inside, and Pmax is the maximum change in the length of the data line when the wheel core rotates one tooth; for example, if the user wants the length of the data line to be adjusted to 2cm in one gear, L1+L2 is 35cm, then the number of teeth can be set to 18.

[0039] Correspondingly, it can be understood that the minimum rotation angle of the wheel core 14 = 360 / the number of gear teeth. The minimum rotation angle corresponds to the wheel core rotating one gear, and the length of the data line changes the least, that is, changes one gear.

[0040] Among them, Figure 2 and Figure 6As shown, the clamping member 152 is connected to the housing 11, and the clamping member 152 has a first protrusion 1521 extending into the groove 1512. The first protrusion 1521 is engaged with different grooves 1512 as the gear member 151 rotates to adjust the rotation angle. It can be understood that the first protrusion 1521 on the clamping member 152 cooperates with the groove 1512 on the gear member 151. Every time the first protrusion 1521 replaces a matching groove 1512, the adjustment component 15 performs a gear switch, and the gear member 151 rotates a corresponding angle with the wheel core 14, and the length of the data cable 2 also expands and contracts by one gear. At the same time, when the gear is switched, the first protrusion 1521 on the clamping member 152 and the gear teeth 1511 on the gear member 151 can collide with each other to produce a prompt sound. It is understood that the number of the first protrusions 1521 is not limited, as long as it can meet the requirements of being able to mesh with the gear teeth of the gear member to achieve gear adjustment, and on the other hand, ensuring smooth rotation during meshing with the gear teeth to avoid meshing failure. Optionally, the number of the first protrusions 1521 can be set to one or two.

[0041] The adjustment component in the embodiment of the utility model is realized by a snap-in groove switched by gear rotation. One gear tooth on the gear corresponds to one gear position. There are many adjustable gears. Users can adjust more different lengths according to their own needs, and a prompt sound can be emitted when switching gears to remind the user that a gear switch has been completed, which can improve the user's experience.

[0042] In some embodiments, Figure 2 As shown, the gear member 151 and the wheel core 14 rotate around the same axis Z, and Z is the symmetry axis of the wheel core 14. That is, the gear member 151 is connected to the wheel core 14 and rotates coaxially with the wheel core 14.

[0043] The gear part and the wheel core in the embodiment of the utility model rotate coaxially, and the rotation angle of the gear part is the angle through which the wheel core rotates. At this time, the rotation angle of the wheel core can be controlled by directly adjusting the rotation angle of the gear part, thereby adjusting the telescopic length of the data cable, making the gear adjustment more accurate and simplifying the structure of the reel.

[0044] In some embodiments, Figure 2As shown, the wheel core 14 includes: a columnar portion 141, a first end portion 142, and a second end portion 143. The columnar portion 141 extends along the axis Z direction; the first end portion 142 and the second end portion 143 are respectively connected to the two ends of the axis Z direction of the columnar portion 141, and the space between the first end portion 142, the second end portion 143 and the columnar portion 141 is used for the data line 2 to be wound around the columnar portion 141; it can be understood that the first end portion 142 and the second end portion 141 are coaxially arranged at the two ends of the columnar portion 141 along the Z axis, and the data line 2 is wound around the columnar portion 141 between the first end portion 142 and the second end portion 143. When the data line 2 is extended and retracted, it will drive the columnar portion 141 to rotate around the Z axis, and at the same time drive the first end portion 142 and the first end portion 143 to rotate coaxially around the Z axis. The first end portion 142 is located on the radially outer side of the columnar portion 141, and the gear member 151 is arranged on the inner side of the first end portion 142 and connected to the columnar portion 141. It can be understood that the gear member 151 is disposed inside the first end portion 142 and connected to the wheel core 14 through the columnar portion 141 . When the columnar portion 141 rotates with the data line 2 being stretched, the gear member 151 rotates together with the wheel core 14 .

[0045] The wheel core in the embodiment of the utility model provides sufficient space for winding the data cable. The first end and the second end fix the data cable to prevent axial movement of the data cable when it is extended or retracted. At the same time, connecting the gear part to the inner side of the wheel core reduces the size of the reel and makes it easier to carry.

[0046] In some embodiments, Figure 4 As shown, the gear member 151 includes: a cover portion 1513 and a toothed portion 1514. The cover portion 1513 and the first end portion 142 are located at the same end of the columnar portion 141; the toothed portion 1514 is arranged at one end of the cover portion 1513 away from the columnar portion 141, and the plurality of gear teeth are arranged at the edge of the toothed portion 1514.

[0047] That is, the lower end (cover 1513) of the gear member 151 along the Z axis is connected to the wheel core 14 through the first end 142, and the toothed portion 1514 protrudes from the cover 1513 in a direction away from the wheel core 14. When the gear member 151 is adjusting the gear position, the cover 1513 can cover the columnar portion 141 as a wheel core end cover.

[0048] In the embodiment of the utility model, the cover body and the toothed portion are integrated, which improves the coaxiality of the wheel core and the toothed portion, ensures the installation accuracy, and reduces the number of parts and the difficulty of assembly.

[0049] In some embodiments, Figure 3 As shown, the clamping member 152 further includes: a connecting portion 1522 and a wheel 1523. The connecting portion 1522 is fixedly connected to the housing 11 (see Figure 2); that is, the clamping member 152 is rotatably connected to the housing 11 through the connecting portion 1522. The wheel disc 1523 is connected to one side of the connecting portion 1522 and can swing relative to the connecting portion 1522; that is, the connecting portion 1522 is arranged at the edge of the wheel disc 1523, and the wheel disc 1523 is rotatably arranged on the housing 11 through the connecting portion 1522. Among them, the first protrusion 1521 protrudes from the edge of the wheel disc 1523 away from the connecting portion 1522 to the side away from the connecting portion 1522. It can be understood that the first protrusion 1521 is arranged on the edge of the wheel disc 1523 close to the gear member 151, and protrudes to the side close to the gear member 151.

[0050] The first protrusion 1521 on the clamping member 152 is clamped with the groove 1512 on the gear member 151. When the gear member 151 rotates, the wheel 1523 swings relative to the connecting portion 1522 as the gear member 151 rotates. Furthermore, a limiting member 154 is provided on the side of the clamping member 152 away from the gear member 151. When the clamping member 152 rotates with the gear member 151, the clamping member 152 is limited.

[0051] In the embodiment of the utility model, the first protrusion on the clamping member protrudes toward the gear member, and the clamping member can swing with the rotation of the gear member, so that the clamping member and the gear member are clamped more tightly, which is convenient for flexible gear position change.

[0052] In some embodiments, Figure 4 As shown, the cable reel 1 further includes a positioning member 153 for fixing the gear position, and the positioning member 153 includes: a chassis 1531 and a second protrusion 1532. The chassis 1531 is rotatably connected to the housing 11 (see Figure 2 ); the second protrusion 1532 protrudes from the chassis 1531 toward the wheel disc 1523, and a plurality of second protrusions 1532 are arranged at intervals along the edge of the chassis 1531; wherein the number of second protrusions 1532 may not be limited. It can be understood that the positioning member 153 is rotatably connected to the housing 11 through the chassis 1531, and the second protrusion 1532 is fixedly arranged on the chassis 1531 and protrudes toward the side close to the wheel disc 1523. When the wheel disc 1523 swings, it cooperates with the positioning member 153 to achieve a fixed gear position. Figure 3 As shown, the wheel disc 1523 is provided with a positioning block 1524 and a toggle block 1525 protruding at intervals, at least a portion of the positioning member 153 is located between the positioning block 1524 and the toggle block 1525, the positioning block 1524 is used to abut between two adjacent second protrusions 1532 to fix the gear position, and the toggle block 1525 is used to toggle the positioning member 153 to rotate. It can be understood that the positioning block 1524 and the toggle block 1525 are provided on the wheel disc 1523 and are provided on two different sides relative to the positioning member 154.

[0053] Among them, as the turntable 1523 swings, the positioning block 1524 and the toggle block 1525 will also rotate together to a certain angle. When the positioning block 1524 swings to cooperate with the positioning piece 154, the gear position can be fixed; when the toggle block 1525 swings to cooperate with the positioning piece 153, the positioning piece 153 can be driven to rotate, preparing for the next cooperation between the positioning block 1524 and the positioning piece 153.

[0054] The embodiment of the utility model enables the reel to accurately fix the gear position after switching the gear position through the cooperation between the positioning piece and the positioning block and the toggle block on the wheel, thereby further improving the user's experience.

[0055] In some embodiments, Figure 4 and Figure 5 As shown, a recessed portion is formed between adjacent second protrusions 1532, and the recessed portion includes a first recessed portion 1534 and a second recessed portion 1535 arranged at intervals. The depth D1 of the first recessed portion 1534 is less than the depth D2 of the second recessed portion 1535. It can be understood that the positioning member 153 is circumferentially spaced to form a plurality of first recessed portions 1534 and second recessed portions 1535 of different depths, and the positioning block 1524 can cooperate with the first recessed portion 1534 and the second recessed portion 1535.

[0056] The working principle of the adjustment component in the embodiment of the utility model is described below. Figure 6 As shown, when the toothed portion 1514 rotates clockwise (when the data cable is recovered), it will drive the wheel 1523 to swing counterclockwise by a certain angle. The positioning block 1524 set on the wheel 1523 gradually approaches the positioning member 153 as the wheel swings and cooperates with the positioning member 153.

[0057] When the positioning block 1524 cooperates with the first recessed portion 1534, due to the limitation of the depth of the first recessed portion 1534, the depth of the positioning block 1524 and the positioning member 153 is shallow, which limits the wheel 1523 from continuing to rotate with the toothed portion 1514, so that the actual rotation angle A1 of the first protrusion is smaller than the angle corresponding to the previous groove 1512 on the toothed portion, that is, A1<A. At this time, the rotation angle of the first protrusion 1521 is not enough to avoid the gear teeth of the toothed portion 1514, which will hinder the toothed portion 1514 from further rotating clockwise. The wheel core 14 cannot continue to rotate clockwise, and the data cable cannot be recovered, fixing the length of the data cable stretched out of the shell, thereby playing a positioning role after the stretching gear.

[0058] like Figure 7As shown, when the positioning member 1524 cooperates with the second recessed portion 1535, due to the greater depth of the second recessed portion, the wheel 1523 rotates with the toothed portion 1514 until the positioning member 1524 abuts against the bottom of the second recessed portion 1535 and stops, so that the rotation angle A2 of the first protrusion 1521 is greater than the angle corresponding to the previous groove 1512 on the toothed portion, that is, A2>A. At this time, the rotation angle of the first protrusion 1521 is sufficient to avoid the gear teeth of the toothed portion 1514, so that the toothed portion 1514 can rotate clockwise without restriction, and the wheel core 14 can also move smoothly clockwise, thereby realizing the smooth retraction of the data cable after the data cable is stretched out.

[0059] The embodiment of the utility model controls the swing angle of the clamping part through different matching modes of the positioning part, thereby realizing positioning of different gears, and has a simple structure. At the same time, the method of parts clamping is used to replace the movement of the ornament on the track, which reduces the wear of the parts and increases the service life of the product.

[0060] In some embodiments, Figure 3 As shown, the toggle block 1525 is a triangular block, so that when the triangular block abuts against the second protrusion 1532, the toggle positioning member 153 is rotated until the triangular block abuts against the adjacent second protrusion 1532 to adjust the gear position. In other words, the toggle block 1525 in the shape of a triangular block is provided on the wheel 1523, the toggle block 1525 can abut against the second protrusion 1532, and the toggle positioning member 153 is rotated by a certain angle, and the angle rotated is exactly the angle between two adjacent second protrusions 1532.

[0061] Among them, Figure 8 As shown, when the toothed portion 1514 rotates counterclockwise (the data line is stretched outward), the wheel 1523 is driven to rotate clockwise, and the toggle block 1525 abuts against the second recessed portion 1532 on the positioning member 153. At this time, the toggle block 1525 will drive the positioning member 153 to rotate to the adjacent second recessed portion. Since the first recessed portion 1534 and the second recessed portion 1535 are arranged at intervals, the positioning block 1524 and the positioning member 153 can be switched to different matching states, thereby playing the role of switching gears.

[0062] The embodiment of the utility model realizes the adjustment of the gear position by setting the toggle block as a triangular block. The toggle angle is accurate, and accurate positioning can be achieved, which is conducive to improving the user experience.

[0063] In some embodiments, Figure 1As shown, there are two openings 13, and the two openings are located on the same diagonal line of the housing 11. It can be understood that the openings arranged on the same diagonal line can enable the data cable to be pulled out in both directions, so that the wheel core is evenly stressed, and can drive the wheel core to rotate counterclockwise to ensure the normal operation of the reel. In addition, the telescopic data cable pulled out in both directions has a larger length adjustment range and is suitable for more scenarios.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
