Description

眼镜快换镜腿的弹性铰链 技术领域
本发明涉及到一种眼镜快换镜腿的弹性铰链。

已往的眼镜 快换镜腿大都是采用弹性卡扣卡到相适配的空心镜脚内，按下弹性卡扣可抽出镜腿，代表性的如CN201145783Y该眼镜结构只有换镜腿的功能没有弹性铰链的功能。
CN200720172754.0 公告了一种'快拆装的眼镜架'。它的目的是提供一种不需要工具就可以拆卸镜腿的眼镜架。该技术方案包括：所述快拆装的眼镜架，包括装头、镜腿，还包括一弹簧弹片和铰链片，所述的弹簧弹片由一呈方孔状的弹性运动部和弹性扣和部组成，所述的铰链片一端设置成与所述弹性运动部匹配的方孔，铰链片上的方孔一端设有切口，铰链片通过切口***到弹性运动部内，铰链片能沿所述弹性运动部做旋转运动，在铰链片和弹性运动部配合形成的空间内设置弹簧，铰链片的另一端设置成圆环状的铰接部，该铰接部与设置在装头上的挂钩配合连接，在镜腿上设有通槽，在设有通槽的镜腿上设有开口，所述的弹簧弹片的弹性扣和部从镜腿的通槽***后，弹性扣和部与所述的开口卡合。该技术方案中出现了弹性铰链的功能，这是一大进步。但该镜架中的弹簧弹片由弹性运动部和弹性扣和部组成，弹性扣和部与弹性运动部串连排列，结构上显得松散不紧凑；该铰链铰接部与设置在装头上的挂钩配合连接的特征局限性太大，使镜腿收拢或打开绕挂钩的弧线，影响了外观且难以取得较好的止位效果；该铰链挂钩的平面与铰链片铰结平面是垂直相交，让装头与镜腿经螺丝连接的方式无法施展，至使该'快拆装的眼镜架'形式单一应用范围狭窄。

本发明下面将结合附图作进一步详述：
图1～ 图10 示出了本发明的第一个实施例。
请参阅图1所示， 所述眼镜 快换镜腿的弹性铰链，包括铰链双齿1、螺丝2、弹簧芯组件3、镜腿4，其中：弹簧芯组件3由弹性扣32、插接在所述弹性扣腹腔内的单齿框31、所述单齿框31与所述弹性扣32组装到位后的弹性扣32腹腔内套装的芯杆33、所述芯杆33上套装的弹簧34组成；所述弹性扣32与镜腿4均设有相适配的扣合部及扣位，使镜腿可拆的与铰链连接在一起。
请参阅图2、图3所示，所述单齿框31由两段互相垂直相交的前段扁平片体311、后段扁平片体312组成，前段扁平片体311外形近似圆形，其上设有圆形通孔3111，与该扁平片体311垂直相交的后段扁平片体312外形近似矩形，其上设有矩形通孔3121、后段扁平片体312尾部沿中心线处自外向内开设有非贯通凹槽3122；所述单齿框31的前段扁平片体311与所述铰链双齿1通过螺丝2活动连接，所述单齿框31后段扁平片体312的非贯通凹槽3122与所述弹性扣32对应部位开设的缺槽3241插套定位，所述单齿框31上的矩形通孔3121用于容置芯杆33及套装在芯杆33上的弹簧34，矩形通孔的底面31211供抵靠弹簧34底面及铰链止位用。
请参阅图4所示，所述弹性扣32包括第一弹片321、第二弹片322、所述第一弹片321与所述第二弹片322于一端端头汇集为一体而成型的尾部323，所述第一弹片321与所述第二弹片322间成型的腹腔324、所述弹性扣腹腔324的尾部沿中心线开设供单齿框31后段尾部的凹槽3122插套定位且与所述腹腔324贯通的缺槽3241、其中第二弹片322位于开口的所述腹腔324内与该弹片322呈垂直状凸设可***所述单齿框31的矩形通孔3121内以供芯杆33定位的悬臂梁325、第一弹片321、在其临近开口端部位向外***而凸设的扣合部3211、所述扣合部3211的端头由顶面3261、竖立部3262合成L型的公扣位326。
请参阅图5所示，所述芯杆33由两段圆柱体组成，头部331相对短粗，杆体332相对细长。
请参阅图6所示，所述弹簧34是普通螺旋弹簧。
请参阅图7～图9所示，所述镜腿4在其一端端部自外向内开设有不贯通的十字槽内腔41，它是由竖向扁孔411及横向扁孔412交叉组成。其中竖向扁孔411供弹性扣32***，横向扁孔412供单齿框31***，两扁孔411、412交叉中心供芯杆33及弹簧34***，位于所述镜腿4壳体的顶端稍后不远处，竖向扁孔411与镜腿4外表面贯通形成一扁形开口4111，即为镜腿4的扣合部，该开口4111适配的供弹性扣32的扣合部3211在此扣合，届时，弹性扣32的上顶面3261与镜腿4的第一短平面421相抵，弹性扣32的竖立部3262与镜腿第二短平面422相靠。在此镜腿4第一短平面421与镜腿4第二短平面422一横一竖构成镜腿4的L型母扣位42。
在其它实施例中，弹性扣32也可不设立竖立部3262，当向外拨动镜腿4，弹性扣32依靠与镜腿壳适配的曲线约束弹片321不向外张开，进而保证弹性扣32的上顶面3261与镜腿4的第一短平面421相抵而不脱离其扣位。
在生产过程中为使安装方便，一般先将单齿框 31 、弹性扣 32 、芯杆 33 、弹簧 34 组装成弹簧芯组件 3 。
弹簧芯组件 3 的装配 请参阅图 1 所示 ， 单齿框 31 用图 2 所示平面摆放状态由敞开处***弹性扣 32 腹腔 324 内，单齿框 31 的尾部 凹槽 3122 经弹性扣 32 的矩形缺槽 3241 向下与弹性扣 32 活动的套插在一起，在单齿框 31 与弹性扣 32 组合的空腔内装入芯杆 33 、弹簧 34 ，弹簧 34 的下端抵靠在单齿框 31 的矩形通孔的底边 31211 ，芯杆杆体 332 插在弹簧 34 孔中，芯杆头部 331 下端抵靠弹簧 34 ，上端抵靠弹性扣 32 的悬臂梁 325 ，弹簧芯组件 3 组装完毕。
把弹簧芯组件 3 装到镜腿 4 内：将焊接在装头 5 上的铰链双齿 1 ，与弹簧芯组件 3 中的单齿框 31 用螺丝 2 螺接后，捏着装头 5 可以将弹簧芯组件 3 经镜腿十字槽内腔 41 向镜腿 4 内***，***时弹性扣 32 先缩径，到位后弹性扣 32 向外凸起的 弹性扣合部 3211 将与镜腿 4 的扁形开口 4111 相适配地扣合在一起，弹性扣 32 的公扣位 326 与镜腿 4 的母扣位 42 相互依靠，使镜腿 4 可拆地与铰链连接在一起。
请参阅图10 所示，向外拨动镜腿4，此时单齿框31仅能绕螺丝2轴线转动，而不能向外移动，镜腿4长边43的端台431紧顶装头下平面51，此时弹性扣32的扣合部3211与镜腿4的扁形开口4111通过公扣位326母扣位42相扣合，至使镜腿4连同弹性扣32只能联体沿图示箭头方向位移，与此同时弹性扣32的悬臂梁325推动芯杆33头部331压缩弹簧34，直至芯杆33尾端顶到单齿框31的矩形通孔底边31211使镜腿4向外摆动停止。在此过程中你会感到镜腿4的弹力，并且镜腿4向外旋转到一定角度会停止(俗称：止位)。在拆卸镜腿4时只需用母指、食指捏压下弹性扣32外露的弹性扣扣合部3211使弹性扣32缩径让弹性扣的公扣位326脱离镜腿4的母扣位42 ,另一只手拉动装头5，即可拆下镜腿4。

请参阅图15～图17 所示 , 所述镜腿4在其一端端部自外向内开设有不贯通的十字槽内腔41，它是由竖向扁孔411及横向扁孔412交叉而成。其中竖向扁孔411供弹性扣32***，横向扁孔412供单齿框31***，位于所述镜腿4壳体的顶端稍后不远处，竖向扁孔411与镜腿上、下外表面贯通形成两个上、下对称的第一扁形开口4111、第二扁形开口4112，此即镜腿4的第一扣合部、第二扣合部，二个开口4111、4112适配的供弹性扣32的第一扣合部3211、第二扣合部3221在此扣合，届时，弹性扣32的第一上顶面3261、第二上顶面3271与镜腿4第一短平面421、镜腿4第三短平面441相抵，弹性扣32的第一竖立部3262、第二竖立部3272与镜腿4第二短平面422、镜腿4第四短平面442相靠。在此镜腿4第一短平面421与镜腿4第二短平面422成型为镜腿4第一母扣位42，所述镜腿4第三短平面441与镜腿4第四短平面442成型为镜腿4第二母扣位44。
在其它实施例中，弹性扣32也可不设立第一竖立部3262、第二竖立部3272，当向外拨动镜腿4，弹性扣32依靠与镜腿壳适配的曲线约束第一弹片321、第二弹片322不向外张开，进而保证弹性扣32的第一上顶面3261、第二上顶面3271与镜腿4的第一短平面421、镜腿4的第三短平面441相抵而不脱离其扣位。
在生产过程中为使安装方便，一般先将单齿框31、弹性扣32、芯杆33、弹簧34组装成弹簧芯组件3。
请参阅图11 所示 ，弹簧芯组件3的装配：单齿框31需在图13所示位置绕对称线旋转90度方能由敞开处***弹性扣32腹腔324内，单齿框31的凹槽3122经弹性扣32的矩形缺槽3241向下与弹性扣32活动的套插在一起，在单齿框31与弹性扣32组合的空腔内装入弹簧34、芯杆33，所述弹簧34的下端抵靠在单齿框31的矩形通孔底边31211，芯杆杆体332插在弹簧34孔中，芯杆头部331抵靠弹簧34，上端抵靠弹性扣32的悬臂梁325，弹簧芯组件3组装完毕。
请参阅图12 所示 ，该弹性扣32的第一扣合部3211、第二扣合部3221外露在镜腿4壳体的两侧面。将焊接在装头5上的铰链双齿1，与弹簧芯组件3中的单齿框31用螺丝2螺接后，捏着装头5可以将弹簧芯组件3经镜腿4的十字槽内腔41向镜腿4内***，***时弹性扣32先缩径，然后，第一扣合部3211和第二扣合部3221与镜腿4的 第一扁形开口4111、第二扁形开口4112 相互扣合，弹性扣32的公扣位326、327与镜腿4的母扣位42、44相互抵靠，使镜腿4可拆地与铰链连接在一起。
请参阅图18 所示，向外拨动镜腿4，此时，单齿框31仅能绕螺丝2轴线转动，而不能向外移动，镜腿4长边43的端台431紧顶装头5下平面51，此时弹性扣32的第一扣合部3211、第二扣合部3221与镜腿4的第一扁形开口4111、第二扁形开口4112通过第一公扣位326、第二公扣位327和第一母扣位42、第二母扣位44相扣合，致使镜腿4连同弹性扣32只能联体沿图示箭头方向位移，与此同时，弹性扣32的悬臂梁325推动芯杆33头部331压缩弹簧34，直至芯杆33尾端顶到单齿框31的矩形通孔底边31211使镜腿4向外摆动停止。在此过程中你会感到镜腿4的弹力，并且镜腿4向外旋转到一定角度会停止(俗称：止位)。在拆卸镜腿4时只需用母指、食指捏压下弹性扣32外露的第一扣合部3211、第二扣合部3221，使弹性扣32缩径，让弹性扣32的第一公扣位326、第二公扣位327脱离镜腿4的第一母扣位42、第二母扣位44，另一只手拉动装头5，即可拆下镜腿4。
以上所述仅为本发明的较佳实施例，凡依本发明权利要求范围所做的均等变化与修饰，皆应属本发明权利要求的涵盖范围。
