弹簧壳 10设有一弹簧芯收容空间 11 , 并在弹簧芯收容空间 11的开口端 设有一对连接孔 12。 弹簧壳 10可用各种金属或合金材料制成， 例如锌白铜、 钛金属或青铜、磷铜等。 优选地， 弹簧壳 10端部设有与弹簧芯收容空间 11相 连通的开口 13, 开口 13两侧分别设有一连接壁 14, 并且每一连接壁 14上设 有连接孔 12。 本实施例中， 弹簧壳 10大致呈矩形， 当然弹簧壳 10也可 ^：各 种适应性的设计变更。
弹簧芯 20容置于弹簧芯收容空间 11内。弹簧芯 20设有一弹簧收容槽 21 , 弹簧收容槽 21 中容置有一弹簧 22。 其实弹簧 22个数也可以是两个以上， 各 个弹簧 22彼此并联， 其在提供足够的弹力基础上可以缩短弹簧芯 20的长度。 本发明弹簧芯 20可采用各种金属或合金材料， 优选经冲压和冷拉挤出成型并 内藏弹簧 22, 其结构简单， 可减少生产工艺以降低成本。 弹簧芯 20在其一端 设有一铰接孔 23，在其另一端设有一抵接部 24, 并且弹簧芯 20的弹簧收容槽 21和铰接孔 23通过一过渡槽 25相连通。
连接件 30优选为销钉或者螺钉等， 连接件 30与弹簧壳 10 (即连接壁 14 上） 的一对连接孔 12活动连接， 这里所述活动连接是指销接或者螺接等可拆 卸式连接方式， 且弹簧 22被压缩限位于连接件 30和弹簧收容槽 21之间。 这 里， 连接件 30和连接孔 12可以设置为多个。
同时结合图 2~7来描述本发明 Θ艮镜架弹簧铰链 100的装配过程：
1 )如图 4所示， 将弹簧 22装置于弹簧芯 20的弹簧收容槽 21中。
2 )如图 5所示， 将弹簧芯 20自 4氏接部 24沿弹簧壳 10的开口 13伸入弹 簧芯收容空间 11内，弹簧芯 20的铰接孔 23露于弹簧壳 10的连接壁 14之夕卜， 将连接件 30插入一对连接孔 12中， 且连接件 30贯穿弹簧芯 20的过渡槽 25。 此时弹簧 22被压缩收容于弹簧收容槽 21的抵接部 24和连接件 30之间，即弹 簧 22的一端支撑在抵接部 24上， 另一端支撑在连接件 30上。
3 )如图 6所示， 通过螺钉 50将铰接孔 23与铰链 40连接系紧， 最终得到 如图 7所示的眼镜架弹簧铰链 100。 其中， 铰链 40与眼镜框连接， 而弹簧壳 10与眼镜腿连接。 通过弹簧芯 20中被压缩弹簧 22的回复力作用， 可方便转 动眼镜腿以使之与眼鏡框收拢或分开。
综上所述， 本发明通过内藏式弹簧芯及连接件（例如销钉）结构来实现眼 镜架弹簧铰链的弹性效果，代替传统弹簧套入以及倒钩结构方式， 内藏式弹簧 芯结构筒单， 可减少生产工艺以降低成本。 再者， 配合内藏式弹簧芯， 只需在 弹簧壳前部进行加工以缩短弹簧壳长度，从而节约空间，有利于整个眼镜架的 设计效果。 并且， 内藏式弹簧芯与弹簧壳可以良好地匹配， 避免了不必要的摆 动。 另外， 内藏式弹簧芯通过连接件限位在弹簧壳中， 由于连接件与弹簧壳采 用活动连接方式， 因此可方便地组装和拆卸。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
