Description

Technical Field

[0001] The utility model relates to the field of clothing button design, in particular to a rotatable snap button. Background Art

[0002] Fasteners are generally used on items such as backpacks, golf bags, and duffel bags. It usually includes two components, a ferrule and a tongue, where the ferrule and the tongue are respectively fixed to one end of two restraint straps on items such as backpacks. When in use, the two restraint straps are combined together through the snap connection of the ferrule and the tongue, so as to pack and tighten items such as backpacks.

[0003] In the prior art (Publication No.: CN2601559Y, Publication Date: February 4, 2004), a fastener with a rotatable ferrule and tongue is disclosed. A circular block is provided on the tongue, and then the circular block is inserted into the slot of the ferrule. Since the circular block will automatically elastically reset, it will be stuck in the through hole on the end face of the ferrule. Since the through hole is a circular structure, the circular block can rotate in the through hole to achieve the effect of a rotating fastener, which is convenient to use.

[0004] In the above-mentioned rotating fastener, a circular block made of the elasticity of plastic itself is used for snap connection. However, since the fastener is integrally injection-molded with plastic, the plastic parts are prone to aging and corrosion, and the overall strength of the plastic parts is low. When the belt is pulled strongly, the fastener is easily broken, so the strength of the fastener still needs to be improved. Summary of the Utility Model
