[0020] To make the technical means, creative features, objectives and effects of the utility model easy to understand

[0021] Understand, the utility model is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 , Figure 2 As shown, the utility model provides a winding device for a shared charging line, including a power adapter 1, the output end of the power adapter 1 is fixedly connected to a code scanning power supply controller 2, a winding box 3 is arranged below the code scanning power supply controller 2, a plug assembly 4 is arranged on the right side of the winding box 3, a power supply wire 32 is fixedly connected to the top of the winding box 3, the output end of the power supply wire 32 is movably electrically connected to a rotary joint 31, the left side of the rotary joint 31 is electrically connected to a winding charging line 34, the plug assembly 4 includes a connecting wire 43, the input end of the connecting wire 43 is electrically connected to the output end of the winding charging line 34, the output end of the connecting wire 43 is electrically connected to a charging three-way head 41, the output end of the charging three-way head 41 is evenly electrically connected to three charging heads 42, and a partition plate 33 is fixedly installed on the inner wall of the winding box 3;

[0023] When charging is required using the three charging heads 42 on the charging three-way head 41, the power adapter 1 can be plugged into the socket first, and power can be drawn by scanning the QR code on the power supply controller 2. Then, the charging three-way head 41 can be directly pulled to make the connecting wire 43 drive the winding charging wire 34 wound on the rotary joint 31 in the winding box 3 to be pulled out, and the rotary joint 31 can be rotated. At this time, the power supply wire 32 is kept at the top of the winding box 3 without moving by using the movable connection with the rotary joint 31.

[0024] like Figure 3As shown, the bottom end of the rotary joint 31 passes through the center of the partition plate 33 and is fixedly installed with an extended bottom rod 311, the bottom end of the extended bottom rod 311 is movably connected to the center of the bottom of the inner wall of the winding box 3, and four rebound boxes 35 are fixedly installed in a circular array at the bottom of the inner wall of the winding box 3, and the extended bottom rod 311 is located on one side of the opposite end of the four rebound boxes 35, and the inner walls of the four rebound boxes 35 are fixedly connected to one side of the extended bottom rod 311, and the other end of the compression spring 351 is fixedly installed with a pull block 352, and the center of the side of the pull block 352 close to the compression spring 351 is fixedly installed with a pull rope 353, the top ends of the four pull ropes 353 pass through the side of the rebound box 35 close to the extended bottom rod 311, and the ends of the four pull ropes 353 away from the pull block 352 are fixedly connected to the outer wall of the extended bottom rod 311;

[0025] When the swivel joint 31 rotates, it will drive the extended bottom rod 311 at the bottom to rotate under the partition plate 33, thereby pulling the pull rope 353 in the four rebound boxes 35, so that the pull blocks 352 in the four rebound boxes 35 compress the compression spring 351 at the same time. After the charging head 42 is inserted into the mobile phone, the swivel joint 31 cannot resume rotation due to the weight of the mobile phone itself. When the charging head 42 is unplugged after charging, the pull rope 353 can be pulled to reset under the rebound action of the compression spring 351 in the four rebound boxes 35, so that the extended bottom rod 311 drives the swivel joint 31 to rotate in the opposite direction and reset, so that the pulled-out reeled charging line 34 is automatically rewound on the partition plate 33 in the inner cavity of the reeling box 3, thereby achieving an automatic rewinding effect and avoiding the inconvenience of storing longer lines when not in use.

[0026] like Figure 4 , Figure 5 As shown, a positioning mechanism 36 is fixedly installed on the top right side of the winding box 3, and a fixed clamping ring 411 is fixedly installed on the right side of the charging three-way head 41. The fixed clamping ring 411 is clamped with the positioning mechanism 36. The positioning mechanism 36 includes a positioning block 361. The outer wall of the positioning block 361 is provided with a rubber anti-slip sleeve 362. The outer wall of the rubber anti-slip sleeve 362 is tightly attached to the inner wall of the fixed clamping ring 411.

[0027] By flipping the charging three-way head 41 and directly clamping it on the positioning block 361 using the fixed clamping ring 411, and using the rubber anti-slip sleeve 362 to maintain stability when clamped, the entire charging three-way head 41 and the charging head 42 are fixed on the top of the winding box 3, thereby facilitating the storage of the charging three-way head 41.

[0028] The following is a detailed description of the working principle of the winding device for the shared charging cable.

[0029] like Figure 1-5As shown, when it is necessary to charge using the three charging heads 42 on the charging three-way head 41, the power adapter 1 can be plugged into the socket first, and the power can be drawn by scanning the QR code on the power supply controller 2, and then the charging three-way head 41 can be directly pulled to make the connecting wire 43 drive the winding charging wire 34 wound on the rotating joint 31 in the winding box 3 to be pulled out, and the rotating joint 31 can be rotated. At this time, the power supply wire 32 remains at the top of the winding box 3 and does not move. When the rotating joint 31 rotates, it will drive the bottom extension rod 311 to rotate under the partition plate 33, thereby pulling the pull ropes 353 in the four rebound boxes 35, so that the pull blocks 352 in the four rebound boxes 35 can simultaneously press the compression springs 3 51 is compressed, and after the charging head 42 is inserted into the mobile phone, the rotating joint 31 cannot resume rotation due to the weight of the mobile phone itself. When the charging head 42 is unplugged after charging, the pull rope 353 can be pulled to reset under the rebound action of the compression spring 351 in the four rebound boxes 35, so that the extended bottom rod 311 drives the rotating joint 31 to rotate in the opposite direction and reset, so that the pulled-out winding charging line 34 is automatically rewound on the partition plate 33 of the inner cavity of the winding box 3, and then the charging three-way head 41 is turned over and directly clamped on the positioning block 361 by the fixed clamping ring 411, and the rubber anti-slip sleeve 362 is used to maintain stability when clamped, so that the overall charging three-way head 41 and the charging head 42 are fixed on the top of the winding box 3.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
