Abstract

The invention discloses a key chain ring with two structures of elastic parts and heteropolar magnetism, which relates to the field of daily necessities. The purpose of this invention is to provide a key chain ring with two structures of elastic parts and heteropolar magnetism. : an elastic member with good elastic performance is used for locking the key ring; an opening and closing structure through heteropolar magnetic mutual attraction is used for locking the key ring; wherein: the specific structure of the elastic member may include spiral elastic A piece, a pressure plate elastic piece, a spring coil elastic piece; the two heteropolar magnetic structures include an A end and a B end at the same time, and the magnetic polarities of the two facing end surfaces are opposite, and can be tightly attracted together. The materials of the various components all belong to metal. In summary, the invention has the beneficial effect of effectively resisting metal fatigue and prolonging service life.

Description

technical field [0001] The invention relates to the field of daily necessities, specifically a key ring. Background technique [0002] The key chain ring is almost one for everyone, and is used to carry a bunch of keys. However, the existing key chain rings are prone to metal fatigue due to long-term use, and their elasticity is greatly weakened, which is easy to cause falling off. Contents of the invention [0003] This invention aims to provide a key chain ring with two structures of elastic parts and heteropolar magnetics. In order to achieve the aforementioned purpose, this invention mainly includes: [0004] A key chain ring with two structures of elastic parts and heteropolar magnetism, which is characterized in that, [0005] Include at least: [0006] An elastic member with good elasticity for locking the key ring; [0007] An opening and closing structure through heteropolar magnetic mutual attraction, used to lock the key ring; [0008] Wherein: the specific ...
