Description

眼镜弹簧铰链
本实用新型涉及眼镜非光学结构的部件,尤其是眼镜弹簧铰链。
现有的眼镜弹簧铰链,存在着锁紧件固定不太牢固,加工难度较大,生产成本较高等弊病。
本实用新型之目的在于公开一种结构牢固、较易加工、成本较低的眼镜弹簧铰链。
眼镜弹簧铰链包括庄头,芯子,联接庄头和芯子的螺钉,套在芯子外的铰链,装在铰链内并套在芯子外的弹簧。铰链内、芯子外装有卡簧。
下面结合附图所示的实施例,对本实用新型作详细的说明。
附图1和2是本实用新型实施例一的主视图和俯视图,附图3和4是卡簧的主视图和左视图。
如附图1~4所示,眼镜弹簧铰链包括庄头1,芯子3,联接庄头1和芯子3的螺钉2,套在芯子3外的铰链4,装在铰链4内并套在芯子3外的弹簧6。铰链4内、芯子3外装有卡簧5。芯子3和庄头1采用不同的金属材料制成,因而它们的接触面具有较强的耐磨性。即使长期使用,接触面依然能够保持良好的滚动作用。铰链4的两壁有凹槽,卡簧5的上、下两个尖端卡在凹槽内,因此卡簧5也具有在铰链4内锁紧芯子3、弹簧6和垫片7的作用,并且卡簧5固定牢固,使零部件不会产生摆动。卡簧5对芯子3起导向作用,具备良好的固定和导向性能。此外,由于卡簧5整体隐蔽在铰链4内,所以使镜腿更美观。
如附图1和2所示,芯子3的尾部与弹簧6之间装有垫片7,使弹簧6的工作更可靠,零部件之间更紧密。
如附图1~2所示,眼镜弹簧铰链装配时,先将弹簧6套在芯子3的外面,将卡簧5装在芯子3上;再将芯子3、卡簧5和弹簧6的组件装入铰链4内;然后用螺钉2联接庄头1和芯子3。组件在外力的作用下,使卡簧5紧紧固定在铰链4的凹槽内形成内卡。卡簧5受力均匀,锁紧安全可靠,改变了以往的固定方法,减少了加工难度,使安装更加简捷方便,从而降低了加工成本。
综上所述,本实用新型具有结构牢固、加工容易、成本低等优点,是一种较理想的眼镜铰链。
在附图所示的实施例一中,眼镜弹簧铰链的外形尺寸为20*2*3·5,卡簧5的外形尺寸为2·8*1·5*2。
