This utility model provides a connection structure between an ear protector and a helmet, comprising a male buckle and a female buckle. The male buckle has a plate-shaped insertion part with a guide slope at the front end and a resiliently deformable limiting pressure plate in the middle. The lower surface of the limiting pressure plate is near the front end of the insertion part and has a locking protrusion, while the upper surface forms a pressing surface. The rear end of the insertion part is used to connect to the ear protector. The female buckle has an insertion frame adapted to the thickness of the male buckle's insertion part. The top surface of the insertion frame has a locking part that engages with the limiting protrusion, and the end of its top surface has an operating window for exposing the pressing surface. In this utility model, the female buckle is used to be installed within the helmet's buffer layer. When the insertion part is inserted into the insertion frame, the locking protrusion engages with the locking part to connect the ear protector to the helmet. Pressing the pressing surface separates the locking protrusion from the locking part, thereby separating the ear protector from the helmet. The overall ear protector installation and removal are convenient and labor-saving, providing a good user experience and wide applicability.
