Description

Technical Field

[0001] The utility model relates to the field of computer hardware, in particular to a magnetic attraction finger ring structure which can prevent an attracted surface from being scratched. Background Art

[0002] With the rapid development of information technology, computers have become an indispensable tool in our daily work and life. In order to further improve work efficiency and user experience, the design and functions of computer peripherals are constantly being innovated and improved.

[0003] Wearable computer peripherals provide convenience to the public, but the connection between wearable peripherals and replacement devices hinders the overall beauty of the peripheral appearance, so traceless links using magnets are gradually emerging.

[0004] The traceless connection using magnets provides a better solution for the use, carrying and overall aesthetics of computer peripherals. However, the place where the magnet contacts the computer peripherals is often easily scratched because the magnet and the attracted surface are more likely to rotate along the magnetic center, and the contact surface between the attracting surface and the magnetic device is easily scratched.

[0005] Although the magnetic connection method has advantages in convenience and aesthetics, it also exposes some problems in actual use. When the magnet contacts the computer peripheral, due to the magnetic force, the suction surface is easily worn during the rotation of the magnet, which not only affects the appearance of the device, but also may shorten the service life of the device. It is necessary to design a magnetic ring structure that prevents the suction surface from being worn. Utility Model Content
