[0021] Compared with the prior art, the cable reel and data cable provided by the utility model have the following advantages:

[0022] 1. The cable reel provided by the utility model defines an outer track and an inner track in a recessed portion by arranging a first boss and a second boss, and arranging a first guide surface, a second guide surface and a third guide surface on the cable reel, so that the cable reel can guide the movement of an external object placed in the recessed portion, and by switching the external object on the outer track and the inner track, the cable reel can realize relative rotation with the external object in one direction, and realize mutual locking in the opposite direction to the direction, and after locking, the two can continue to rotate relative to each other by moving the external object;

[0023] Specifically, a first direction and a second direction are set, one is clockwise and the other is counterclockwise; an external object is placed in the outer track, the external object rotates in the first direction relative to the cable reel, and the external object moves to the first guide surface on the outer track after rotating a certain distance, and the first guide surface will guide the external object to move from the outer track to the inner track, and thereafter the external object can continue to rotate in the first direction relative to the cable reel on the inner track; thereafter, by making the external object rotate in the second direction relative to the cable reel, the external object moves to the second guide surface on the inner track after moving a certain distance, and the second guide surface will guide the external object to move to the retaining groove on the first boss, so that the external object is retained in the retaining groove in the second direction, thereby limiting the relative rotation of the external object and the cable reel; and when the external object is further rotated in the first direction, the external object is guided into the outer track by the third guide surface in the retaining groove, and the external object can realize relative rotation in the second direction with the cable reel in the outer track, and when rotating in the first direction, the external object will enter the inner track again to realize cyclic switching of the inner and outer tracks;

[0024] In summary, the cable reel and the external object placed on the cable reel can rotate relative to each other in a certain direction, and can be stopped and locked in the direction opposite to the direction. The free rotation state and the stopped and locked state of the two can be switched to each other, providing specific states according to user needs.

[0025] 2. The utility model provides a fourth guide surface on the outer track of the cable reel, which is connected to the first guide surface. Since the external object can rotate freely in the outer track along the second direction relative to the cable reel, the fourth guide surface is provided to limit the movement speed of the external object during relative rotation to avoid excessive relative rotation of the two. At the same time, the fourth guide surface is connected to the first guide surface to make the movement of the external object in the outer track smoother.

[0026] 3. The recessed portion of the cable reel provided by the utility model includes an inner wall and an outer wall, and the first boss and the second boss are arranged between the inner wall and the outer wall. The first boss and the second boss are arranged in a ring shape along the shape of the recessed portion, so that after the foreign objects are placed in the recessed portion, it is not easy to fall off the track during the movement. The annular structure of the cable reel and the boss can avoid jamming during relative rotation.

[0027] 4. The utility model provides a cable reel with four first bosses and four second bosses, and four corresponding first guide surfaces and two second guide surfaces. By setting four groups of bosses and guide surfaces, external objects and the cable reel can be stopped more quickly, while avoiding too many stopping structures that affect the smoothness of the relative rotation process.

[0028] 5. The utility model also provides a retractable data cable, which includes a hollow shell, in which a winding assembly, a rebound assembly and a data cable are arranged, the data cable is wound on the winding assembly, and at least one end of the data cable is exposed from the shell, a positioning shaft is arranged on the inner wall of the shell, and the two ends of the rebound assembly are respectively connected to the positioning shaft and the winding assembly; the winding assembly includes a rotating part and a winding reel, the shell is rotatably connected to the rotating part on one side away from the positioning shaft, a guide column is arranged on the rotating part, and the guide column is placed in the outer track or the inner track.

[0029] When the user pulls the data cable outward, the data cable drives the cable reel to rotate. During this process, the guide post moves from the outer track of the cable reel to the inner track and rotates within the inner track; after the user releases the data cable, under the action of the rebound component, the cable reel rotates in the opposite direction to the previous direction, and the guide post moves from the inner track to the locking groove and locks, so that the cable reel and the rotating part are locked with each other, thereby fixing the data cable extending on the cable reel at a certain length, which is convenient for the user to use the data cable of the required length; continue to pull the data cable, the guide post can be pulled from the locking groove into the outer track, and the data cable is released after entering the outer track. The guide post can rotate freely relative to the cable reel on the outer track, so that the data cable can automatically retract, which is convenient for the user to store the data cable after use.

[0030] 6. The resilient component of the telescopic data cable provided by the utility model is configured as an elastic sheet, a placement groove is provided on the baffle plate of the cable reel, the recessed portion surrounds the placement groove, the elastic sheet is placed in the placement groove, the positioning shaft portion is exposed in the placement groove, and both ends of the elastic sheet are respectively connected to the positioning shaft and the cable reel; by placing the elastic sheet in the placement groove, the overall structure of the data cable is made more compact, and the volume of the data cable is reduced.

[0031] 7. The telescopic data cable provided by the utility model also includes a fixing part, one side of which is clamped on the cable reel and covers the placement slot. Since the elastic sheet in the placement slot needs to be continuously compressed and restored during use, its large deformation may cause it to slip out of the placement slot. By setting the fixing part, the elastic sheet can be limited to prevent it from slipping out of the placement slot, thereby improving the stability of the telescopic function of the data cable.

[0032] 8. The retractable data cable provided by the utility model also includes a circuit board and a connector. One end of the data cable is electrically connected to the circuit board, and the connector is electrically connected to the side of the circuit board away from the winding assembly. By setting the circuit board and the connector, the data cable can be connected to more types of devices. Specifically, a conductive ring is set on the circuit board, and the connector includes a conductive spring. The conductive ring and the conductive spring are in contact and electrically connected. The circuit board and the winding reel are connected and rotate synchronously, which makes the electrical connection between the circuit board and the data cable more stable. At the same time, the circuit board and the connector are electrically connected through the conductive ring and the conductive spring, which can make the connector and the rotating circuit board stably electrically connected, thereby improving the electrical connection stability of the data cable.

[0033] 9. The retractable data cable provided by the utility model also includes a positioning piece, which is connected to the shell, and the exposed end of the data cable passes through the positioning piece, and a positioning block is arranged on the data cable, and the positioning block is clamped with the positioning piece; by setting the positioning piece and clamping the exposed part of the data cable, the data cable can be prevented from entering the shell too much when the data cable is automatically retracted, and a sufficient length of the data cable can be reserved outside the shell for the user to pull out and use.

[0034] 10. The utility model also provides a charging device, which has the same beneficial effects as the above-mentioned retractable data cable. At the same time, the charging device is a movable power connection device. Since the data cable on it can be retracted and stored in the shell of the socket, its size is smaller and the storage is more convenient; and the connection distance between the charging device and the power supply can be adjusted by retracting the data cable, and the length of the data cable can be adjusted according to different power supply positions, which can be more convenient for users to use.
