Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, and particularly relates to a wire winding device for a power adapter. Background Technique

[0002] A power adapter is a power supply conversion device for small portable electronic devices and electrical appliances. For example, common mobile phone chargers and computer chargers generally consist of components such as a shell, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output for use by electrical equipment. Existing power adapters have power cords either fixed to the adapter or separated from the adapter. For a power adapter with a fixed power cord, after use, the power cord scatters outside the power adapter, easily causing the power cord to be entangled with other wires. The usual solution is to fold the power cord and then fix it with a binding wire. However, during the movement of the power adapter, the binding wire is likely to come loose, resulting in the power cord dispersing again, with poor usage effects and inconvenience when the power adapter is used again or stored.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , the present invention provides two technical solutions:

[0027] The first implementation method: a wire winding device for a power adapter, including a storage shell 1, a limiting member 2 and a storage assembly 3.

[0028] The storage shell 1 is composed of two half shells, which are fixedly connected by bolts between the two half shells. Two symmetrically distributed placement grooves 11 are opened inside the storage shell 1. An electrical connection head 12 is embedded on one inner wall of the placement groove 11. The two electrical connection heads 12 are electrically connected by a connecting wire embedded in the storage shell 1. Diagonal wire outlet grooves 13 are opened at both ends of the storage shell 1. The wire outlet grooves 13 are communicated with the placement grooves 11. A wire guiding groove 14 is opened on one side of the notch of the wire outlet groove 13. A storage groove 15 is opened at the end of the wire guiding groove 14. The storage groove 15 can store the power adapter head. Two dovetail chutes 16 are opened on both sides of the storage shell 1.

The dovetail sliders 23 are located in the dovetail chutes 16, playing a guiding role, enabling the limiting cover 21 to move linearly, and at the same time limiting the limiting cover 21 on the storage shell 1. One end of the dovetail slider 23 is connected to the inner wall of one end of the dovetail chute 16 through a first spring 24. The setting of the first spring 24 enables the limiting cover 21 to automatically press and limit the power adapter head.

[0030] The storage component 3 is embedded inside one side of the storage case 1, and one end of the storage component 3 is located in the placement groove 11 for storing the power cord. The storage component 3 includes a storage roller 31 arranged in the placement groove 11. One end of the storage roller 31 is connected to the electrical connection head 12 through a rotary connector. The power cord is wound around the storage roller 31, and the power cord is electrically connected to the rotary connector on the storage roller 31. The other end of the storage roller 31 is connected with an adjusting member 32. The adjusting member 32 is embedded inside one side of the storage case 1. An annular block 33 is arranged on the outer side of the adjusting member 32. The annular block 33 is fixed on the inner wall of the other side of the placement groove 11. A plurality of fixing teeth 34 distributed in an annular array are fixed on the inner side wall of the annular block 33.

[0031] The second implementation mode, the main difference from the first implementation mode is that: the adjusting member 32 includes a connecting column 321 fixed in the middle of the other end of the storage roller 31. An extension plate 322 is fixed on the outer side of one end of the connecting column 321. The extension plate 322 is located inside the annular plate. The other end of the connecting column 321 penetrates through a through hole opened on the storage case 1 and is fixed with a turntable 323. The turntable 323 is located outside the storage case 1. Grooves 324 are opened at both ends of the extension plate 322. A movable tooth 325 is arranged in the groove 324. One end of the movable tooth 325 is adapted to the fixing tooth 34, playing a role in limiting to prevent the storage roller 31 from rotating. The other end of the movable tooth 325 is connected to the bottom of the groove 324 through a second spring 326. The movable tooth 325 is tightly engaged with the fixing tooth 34 under the action of the second spring 326. A screw groove 327 is opened in the middle of the other end of the connecting column 321. The opening of the screw groove 327 extends to the middle of the outer side of the turntable 323. The bottom of the screw groove 327 is respectively communicated with the two grooves 324 through a through groove 328. A screw column 329 is connected inside the screw groove 327 through internal and external threads. One end of the screw column 329 penetrates through the groove 324 through a connecting rope 320 and is connected to the movable tooth 325.

[0032] When the power cord needs to be stored, turn the knob 3201 at this time. The knob 3201 drives the stud 329 to rotate. The stud 329 cooperates with the thread groove 327 to drive the connecting rope 320 to move. The connecting rope 320 drives the movable tooth 325 to move into the groove 324, separating the movable tooth 325 from the fixed tooth 34 and releasing the limit of the storage roller 31. Then, drive the turntable 323 to rotate through the handle 3202. The turntable 323 drives the storage roller 31 to rotate, and the power cord is stored on the storage roller 31. After the power cord is stored, place the power adapter at the end of the power cord into the storage groove 15. Before that, move the limit cover 21 to expose the storage groove 15. When the power adapter is placed properly, release the limit cover 21. The limit cover 21 resets under the action of the first spring 24 and cooperates with the storage groove 15 to limit the power adapter. Then, turn the knob 3201 in the reverse direction. The knob 3201 drives the stud 329 to move in the reverse direction, so that the movable tooth 325 is not stressed. At this time, the movable tooth 325 meshes with the fixed tooth 34 under the action of the second spring 326, limiting the storage roller 31, and further making the storage of the power cord stable and not easily pulled out.
