Abstract

The invention discloses a key chain capable of preventing a key ring from loosening. The key chain comprises a main key chain body, wherein the main key chain body is connected with a key ring througha locking assembly; the locking assembly comprises a locking piece and a locking shell which are matched with each other; a self-locking mechanism is also arranged in the main key chain body; and theself-locking mechanism comprises a limiting piece, an elastic piece and a positioning piece. According to the product, a traditional elastic metal ring structure is abandoned; a semi-open metal ringwith a hat-shaped characteristic is adopted and is cooperated with a buckle structure corresponding to the semi-open metal ring, so the key ring is prevented from falling off under pulling of externalforce, and reliability is improved; an inwards-concave protruding structure is designed on a buckle part of the key chain, so the risk that thread residues and cloth are clamped in during normal useis reduced as much as possible, the shaking feeling of a buckle caused by technological factors is reduced, and the quality of the key chain is improved.

Description

technical field [0001] The invention relates to a key chain, in particular to a key chain which prevents the key ring from getting loose. Background technique [0002] The key chain is a kind of item that is carried on a daily basis. Because it usually has a hook structure with safety, it is convenient to hang on the waistband of the trousers and the key strap in the bag. It is a very practical small item. [0003] Due to technological factors, there are often obvious gaps between the buckle part of the keychains on the market and the main body of the keychain, which seriously affects the quality of the keychain. When pulled by an external force, it is easy to loose the buckle, causing the key The buckle slips off and gets lost, bringing unnecessary distress and trouble to life. [0004] Furthermore, it is known that an elastic metal ring is used to "circle" items such as keys at present, but when installing and dismounting small items such as keys, the key ring of this mod...
