Description

Technical Field

[0001] This utility model relates to the field of power supply accessories technology, and in particular to a power adapter cable winding device. Background Technology

[0002] Power adapters are essential accessories for electronic devices, and their cables are used to connect the power source to the device. Existing power adapter cables are typically of fixed length. When in use, excessively long cables are prone to tangling and knotting, and the cables are constantly exposed, making the connectors susceptible to damage from bending and friction, thus affecting their lifespan. There is a lack of dedicated storage structures, and users often store them by wrapping the adapter itself, further exacerbating cable fatigue and connector damage. Therefore, we propose a power adapter cable reel device. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a power adapter cable winding device. By setting a cable winding mechanism, the cable can be easily wound onto the winding spool, avoiding tangling and knotting. It is convenient to store and saves space. The cable winding mechanism, together with the locking mechanism, allows for free adjustment of the cable extension length to meet the needs of different usage scenarios. The locking is also secure, preventing the cable from loosening during use. The cable is stored inside the housing, avoiding direct bending and friction at the interface. The overall structure is simple, the manufacturing cost is low, the assembly is convenient, and it is compatible with various specifications of power adapters, making it highly practical.
