本申请要求于2021年11月26日提交国家知识产权局、申请号为202111435820.X、申请名称为“一种手柄组件及跳绳”的中国专利申请的优先权,以及于2022年4月26日提交国家知识产权局、申请号为202210456899.2、申请名称为“一种手柄组件及跳绳”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及运动器械领域,尤其涉及一种手柄组件及跳绳。
背景技术
跳绳运动是一项全身性的有氧运动,可以健身和健心,还有减肥的功效。现有的跳绳包括两个手柄和连接于两个手柄之间的线绳,在使用时使用者双手各持一个手柄,通过摆动手柄实现线绳的摇动。
由于不同身高/体重的用户在跳绳时所需要的跳绳长度不一,对于长度固定的跳绳,由于用户无法自由调整跳绳长度,因此跳绳过程中非常不便利,目前现有技术中提供了一种可调节长度的跳绳,采用较简单的对折结构,把多余的线绳对折后留在手柄处,但是多余线绳会妨碍运动并且有可能在用户运动过程中打到用户的手臂。
发明内容
本申请实施例提供一种手柄组件及跳绳,兼具结构简单,以及通过操作调节轮实现线绳的长度调节。
为达到上述目的,本申请实施例采用如下技术方案:
第一方面,本申请实施例提供一种手柄组件,手柄组件包括安装壳、绕线轴和调节轮。安装壳具有容纳槽,绕线轴可转动地安装于容纳槽内。绕线轴用于固定线绳的一端,并且绕线轴的部分外周面用于供线绳绕设;绕线轴的外周面和容纳槽的内壁之间形成间隙,间隙用于容纳绕设于绕线轴的外周面的线绳,线绳的另一端从安装壳出线口穿出。调节轮可活动地安装于绕线轴,用于使绕线轴在锁止状态和自由状态间切换。绕线轴处于锁止状态,绕线轴沿周向限位于安装壳,以限制线绳位于安装壳外部分的长度;绕线轴处于自由状态,绕线轴能够相对安装壳转动,以调节线绳位于安装壳外部分的长度。
本申请实施例提供的手柄组件,绕线轴转动安装在安装壳内,线绳的一端部可以固定于绕线轴并且部分绕设在绕线轴外周。在操作调节轮将绕线轴切换至自由状态时,通过分别在两个转动方向上转动绕线轴,可增加或减少绕设在绕线轴外周的线绳长度以进行收线或放线,从而调节了穿出安装壳的线绳长度。另外用手捏住外露的线绳向外抽拉,可增加穿出安装壳的线绳长度。在操作调节轮将绕线轴切换至锁止状态时,绕线轴会沿周向限位于安装壳,限定了线绳穿出安装壳的长度。该手柄组件包含较少的零件,结构简单,通过操作调节轮即可实现线绳的长度调节,使用方便。相比于现有采用对折结构的跳绳,本申请手柄组件不存在多余线绳妨碍运动的情况,用户体验 更好。
结合第一方面,在第一方面的第一种可能的实现方式中,绕线轴具有相对设置的第一端和第二端,绕线轴的第一端或中部用于固定线绳的一端。绕线轴的外周面为光滑面,线绳的一部分能够在由绕线轴的第一端至第二端的方向一圈圈地绕设在绕线轴的外周面。出线口位于安装壳靠近绕线轴的第二端处,出线口的内径和线绳的外径相适配。本申请实施例的手柄组件无需在绕线轴上设置螺旋槽,也无需在安装壳上设置长条形窗口或者增加导线机构,就能将线绳有顺序的设置在绕线轴外周并位于安装壳的容纳槽内。本申请手柄组件中供线绳穿出安装壳的出线口可制作的较小,出线口对穿出安装壳的线绳有限位作用,两个手柄组件对使用者的双手的作用力差异较小,两个手柄组件受力平衡,用户体验提升。在安装壳设置较小的出线口,可获得较好的外观性。还有,无需设置导线机构,结构简单,降低调节时的卡线情况。
结合第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,绕线轴用于绕设线绳的外周面设有锥度,在由绕线轴的第一端至第二端的方向绕线轴的外径逐渐变大。在旋转轴转动的过程中,线绳绕在绕线轴有锥度的外周面上,在下一圈线绳对上一圈线绳的作用力下,上一圈线绳更容易向绕线轴的线绳固定位置滑动,这样线绳会从线绳固定位置开始一圈圈地绕在绕线轴上。
结合第一方面的第一种可能的实现方式或第二种可能的实现方式,在第一方面的第三种可能的实现方式中,间隙能够容纳一层绕设于绕线轴的外周面的线绳。通过对安装壳、绕线轴和线绳设置合适的尺寸,使得在绕线轴的径向只能绕设一圈线绳。在绕线轴的第一端至第二端的方向,线绳会从线绳固定位置开始一圈圈地绕在绕线轴上,而不会引起线绳的混乱。
结合第一方面的第一种可能的实现方式至第三种可能的实现方式中任一项,在第一方面的第四种可能的实现方式中,出线口的边缘设置圆角,这样可降低在调节线绳时线绳和安装壳出线口内壁之间的摩擦力,便于线绳在出线口处的出入。
结合第一方面的第一种可能的实现方式至第四种可能的实现方式中任一项,在第一方面的第五种可能的实现方式中,安装壳在靠近出线口处设有用于导引线绳的滚动件,在调节线绳过程中,滚动件和线绳之间为滚动摩擦,有效降低线绳的摩擦力,便于调节线绳。
结合第一方面的第一种可能的实现方式至第五种可能的实现方式中任一项,在第一方面的第六种可能的实现方式中,容纳槽的内壁设有锥度,在由绕线轴的第一端至第二端的方向容纳槽的内壁的内径逐渐变大。在通过转动调节轮来放线的时候,将容纳槽在绕线轴的第二端的内径制作的较大,这样可降低线绳和容纳槽内壁之间的摩擦力,便于在转动调节轮时线绳的送出。
结合第一方面的第一种可能的实现方式至第六种可能的实现方式中任一项,在第一方面的第七种可能的实现方式中,手柄组件还包括手柄本体,安装壳转动安装于手柄本体,安装壳的转动轴线和绕线轴的转动轴线相重合。采用安装壳相对手柄本体转动的方式,在跳绳运动时可实现线绳的快速摇动,线绳不会打结,使用体验更好。
结合第一方面的第七种可能的实现方式中任一项,在第一方面的第八种可能的实现方式中,绕线轴的第一端朝向手柄本体设置,绕线轴的第二端背向手柄本体设置。即绕 线轴的线绳固定位置靠近手柄本体设置,而出线口在安装壳远离手柄本体的位置。或,绕线轴的第二端朝向手柄本体设置,绕线轴的第一端背向手柄本体设置。即绕线轴的线绳固定位置远离手柄本体设置,而出线口在安装壳靠近手柄本体的位置。
结合第一方面至第一方面的第八种可能的实现方式中任一项,在第一方面的第九种可能的实现方式中,安装壳具有盖体,绕线轴沿绕线轴的轴向限位于盖体;盖体或绕线轴设有齿圈;调节轮套设于或穿设于绕线轴的一端,调节轮能够沿绕线轴的轴向在第一位置和第二位置间移动;当调节轮在第一位置时,调节轮的凸齿和齿圈相啮合,调节轮沿周向限位于盖体;当调节轮在第二位置时,调节轮的凸齿和齿圈相分离,绕线轴能够相对于盖体转动。通过沿着绕线轴的轴向改变调节轮的位置,即可实现绕线轴在锁止状态和自由状态之间切换,操作方便。齿圈具有周向布置的多个齿槽,调节轮的凸齿可以和齿圈的齿槽配合。在需要限定线绳长度时,改变调节轮的轴向位置,将调节轮的凸齿和齿圈相啮合,这样绕线轴切换至锁止状态,调节轮和绕线轴均不能转动,限定了穿出安装壳的线绳长度。在需要调节线绳长度时,改变调节轮的轴向位置,将调节轮的凸齿和齿圈相分离,这样绕线轴切换至自由状态绕线轴可以转动,就能按需调节穿出安装壳的线绳长度。
结合第一方面的第九种可能的实现方式,在第一方面的第十种可能的实现方式中,齿圈设于盖体上且与盖体的过孔同轴设置,绕线轴穿设于过孔能够相对盖体转动,绕线轴和调节轮之间通过销钉连接,销钉沿绕线轴的径向安装在绕线轴上,调节轮具有沿调节轮的轴线延伸的导向槽,销钉的端部可滑动地安装于导向槽。在装配绕线轴时,绕线轴穿过盖体的过孔,绕线轴的外周面和过孔配合,使绕线轴可相对盖体转动。在绕线轴切换至自由状态并且调节轮转动时,调节轮通过销钉带动绕线轴转动,实现两者相对盖体同步转动。在改变调节轮的轴向位置时,由于绕线轴已被限定轴向位置,通过安装在绕线轴的销钉和调节轮的导向槽配合来限定调节轮的移动范围,使得调节轮能够沿绕线轴的轴向在第一位置和第二位置间移动。
结合第一方面的第十种可能的实现方式,在第一方面的第十一种可能的实现方式中,调节轮的外周面设有弹性端子,调节轮的内周面间隔设置有第一凹槽和第二凹槽。当调节轮在第一位置时,弹性端子抵设于第一凹槽,以限定调节轮的轴向位置使得凸齿和齿圈保持相啮合,限定线绳伸出安装壳的长度。当调节轮在第二位置时,弹性端子抵设于第二凹槽,以限定调节轮的轴向位置使得凸齿和齿圈保持相分离,有效降低收线或放线过程中凸齿进入齿圈的可能性。
结合第一方面的第九种可能的实现方式,在第一方面的第十二种可能的实现方式中,齿圈设于盖体上且与盖体的过孔同轴设置,调节轮穿设于过孔,绕线轴具有沿调节轮的轴线延伸的限位槽,凸齿可滑动地安装于限位槽,使得调节轮能够沿绕线轴的轴向在第一位置和第二位置间移动。绕线轴的限位槽和齿圈的一个齿槽的横截面形状是相同的,且两者均沿绕线轴的轴线延伸,这样调节轮的凸齿可以在齿圈的一个齿槽和限位槽内滑动,以使调节轮可沿绕线轴的轴向移动。当调节轮的凸齿滑动至限位槽和齿圈的一个齿槽时,即凸齿同时和限位槽、齿圈的一个齿槽啮合,调节轮移动至第一位置,实现调节轮和绕线轴周向限位在盖体上而不能转动。通过向内推调节轮至第二位置,使得调节轮的凸齿滑动至限位槽,凸齿和限位槽保持啮合,而凸齿分离齿圈,这 样就能转动调节轮并带动绕线轴转动,使调节轮和绕线轴能够相对于盖体同步转动。
结合第一方面的第十二种可能的实现方式,在第一方面的第十三种可能的实现方式中,盖体活动安装有按键,或,安装壳外套设有具有过线口的筒状壳并且筒状壳活动安装有按键;调节轮和绕线轴之间设有第一弹性件。当按键未按下时,在第一弹性件的弹性力下,调节轮处于第一位置,调节轮抵设于按键。当按键被按下时,按键抵设于调节轮,调节轮切换至第二位置,第一弹性件被压缩。通过在调节轮和绕线轴之间设置第一弹性件,使得被按压后的调节轮在松开后具有复位的能力,这样操作性更好。
结合第一方面的第十三种可能的实现方式,在第一方面的第十四种可能的实现方式中,调节轮具有定位柱,定位柱的端部可滑动地安装于绕线轴的定位槽;第一弹性件套设于定位柱外,第一弹性件的两端分别抵设于绕线轴和调节轮。这样可限定第一弹性件的位置。通过定位柱和定位槽的配合,可以将绕线轴更稳定地支撑在调节轮上。或,绕线轴具有定位槽,第一弹性件的两端分别抵设于定位槽的底面和调节轮。这样容易装配第一弹性件,可限定第一弹性件的位置。
结合第一方面的第十三种可能的实现方式或第十四种可能的实现方式,在第一方面的第十五种可能的实现方式中,按键和调节轮之间通过弹性扭转件连接,弹性扭转件用于在按键被按下时对绕线轴提供扭力,以使绕线轴转动而线绳自动绕设于绕线轴的外周面。通过在按键和调节轮之间设置弹性扭转件,并使弹性扭转件朝向一个预定方向扭转以蓄能,在弹性扭转件朝向反向扭转时将会释能,带动绕线轴进行多圈的转动复位,使绕在绕线轴上的线绳具有一个内缩力,线绳可以自动向安装壳内部收缩并绕在绕线轴外。在配置有弹性扭转件后,收放线操作更简单。

参阅图1至图3,本申请实施例提供一种手柄组件100,手柄组件100用于与线绳200连接。图1至图3中展示了一个手柄组件100和一部分的线绳200,一根跳绳通常有两个手柄组件100,线绳200连接在两个手柄组件100之间。手柄组件100包括安装壳110、绕线轴120和调节轮130。安装壳110具有容纳槽1111,绕线轴120可转动地安装于容纳槽1111内。结合图4至图6,绕线轴120用于固定线绳200的一端,并且绕线轴120的部分外周面用于供线绳200绕设;绕线轴120的外周面和容纳槽1111的内壁之间形成间隙,间隙用于容纳绕设于绕线轴120的外周面的线绳200,线绳200的另一端从安装壳110出线口1112穿出。调节轮130可活动地安装于绕线轴120,用于使绕线轴120在锁止状态和自由状态间切换。绕线轴120处于锁止状态,绕线轴120沿周向限位于安装壳110,以限制线绳200位于安装壳110外部分的长度;绕线轴120处于自由状态,绕线轴120能够相对安装壳110转动,以调节线绳200位于安装壳110外部分的长度。
本申请实施例提供的手柄组件100,绕线轴120转动安装在安装壳110内,线绳200的一端部可以固定于绕线轴120并且部分绕设在绕线轴120外周。在操作调节轮130将绕线轴120切换至自由状态时,通过分别在两个转动方向上转动绕线轴120,可增加或减少绕设在绕线轴120外周的线绳200长度以进行收线或放线,从而调节了穿出安装壳110的线绳200长度。另外用手捏住外露的线绳200向外抽拉,可增加穿出安装壳110的线绳200长度。在操作调节轮130将绕线轴120切换至锁止状态时,绕线轴120会沿周向限位于安装壳110,限定了线绳200穿出安装壳110的长度。该手柄组件100包含较少的零件,结构简单,通过操作调节轮130即可实现线绳200的长度调节,使用方便。相比于现有采用对折结构的跳绳,本申请手柄组件100不存在多余线绳妨碍运动的情况,用户体验更好。
在一种作为对比例的可调节长度跳绳中,该跳绳的手柄包括安装壳和转动安装在安装壳内的绕线轴,绕线轴的外周面具有螺旋槽,线绳的一端固定在绕线轴的一端,线绳的一部分绕设在螺旋槽上。为了便于线绳穿出安装壳,安装壳上设置有对应螺旋槽的长条形窗口,使得线绳由长条形窗口穿出安装壳外。采用该对比例的跳绳做跳绳运动时,使用者双手各抓住一个手柄,长条形窗口难以对线绳进行限位,穿出于安装壳的线绳朝向随机性较大,使得在两个手柄上穿出线绳的出线角度可能存在差异较大的情况,两个手柄受力不平衡,用户体验不好。此外,在安装壳制作一个长条形窗口,外观性欠佳。
在另一种作为对比例的可调节长度跳绳中,跳绳的手柄包括安装壳和转动安装在 安装壳内的绕线轴,绕线轴的外周面具有螺旋槽,安装壳不设置长条形窗口,而在安装壳上增加复杂的导线机构来导引线绳的移动,这样安装壳的出线孔可以设置得较小以降低跳绳运动时两个手柄受力不平衡问题,然而,在引入导线机构后结构复杂,在调节线绳时容易卡线。
本申请实施例的手柄组件100在设置绕线轴120和线绳200时,参阅图2至图4,绕线轴120具有相对设置的第一端120a和第二端120b,绕线轴120的第一端120a或中部用于固定线绳200的一端。绕线轴120的外周面为光滑面,线绳200的一部分能够在由绕线轴120的第一端120a至第二端120b的方向一圈圈地绕设在绕线轴120的外周面。出线口1112位于安装壳110靠近绕线轴120的第二端120b处,出线口1112的内径和线绳200的外径相适配。其中,绕线轴120的中部位于绕线轴120的第一端120a和第二端120b之间。绕线轴120的外周面为光滑面,可以是圆柱面或弧形面。出线口1112的内径和线绳200的外径相适配是指出线口1112的内径稍微大于线绳200的外径,出线口1112的大小供线绳200穿过即可,无需设置如对比例中对应螺旋槽的长条形窗口。出线口1112和线绳200的横截面可以为圆形或其它形状,这里不作限定。
参阅图3,线绳200的一端部固定在绕线轴120的第一端120a或中部(以下称为线绳固定位置),线绳200的一部分可以固定绕制在绕线轴120的线绳固定位置附近。线绳200是一圈圈绕在绕线轴120的外周面,即线绳200有顺序地单层绕制在绕线轴120的外周面,绕在绕线轴120上的线绳200相对于绕线轴120的轴线是具有一定斜度的。在使绕线轴120转动以将线绳200绕在绕线轴120外的过程中,每绕入一圈线绳200,准备绕在绕线轴120的下一圈线绳200就会对已经绕在绕线轴120的上一圈线绳200有一个作用力,将上一圈线绳200向绕线轴120的线绳固定位置推动一些距离,最终推满整个绕线轴120用于绕线的外周面,并且使线绳200有序排列,不重叠缠绕。需要在绕线轴120上释放线绳200时,可通过向外抽拉线绳200或反向转动绕线轴120,实现穿出安装壳110的线绳200长度的增加。
相比于上述对比例的跳绳,本申请实施例的手柄组件100无需在绕线轴120上设置螺旋槽,也无需在安装壳110上设置长条形窗口或者增加导线机构,就能将线绳200有顺序的设置在绕线轴120外周并位于安装壳110的容纳槽1111内。本申请手柄组件100中供线绳200穿出安装壳110的出线口1112可制作的较小,在两个手柄组件100的出线口1112朝向相同时,使用者双手各抓住一个手柄组件100,两侧线绳200穿出于两侧手柄组件100的安装壳110的朝向相接近,出线口1112对穿出安装壳110的线绳有限位作用,两个手柄组件100对使用者的双手的作用力差异较小,两个手柄组件100受力平衡,用户体验提升。在安装壳110设置较小的出线口1112,可获得较好的外观性。还有,无需设置导线机构,结构简单,降低调节时的卡线情况。
在一些实施例中,为了便于线绳200一圈圈地绕在绕线轴120上,参阅图2、图3,绕线轴120用于绕设线绳200的外周面设有锥度,在由绕线轴120的第一端120a至第二端120b的方向绕线轴120的外径逐渐变大。在旋转轴1114转动的过程中,线绳200绕在绕线轴120有锥度的外周面上,在下一圈线绳200对上一圈线绳200的作用力下,上一圈线绳200更容易向绕线轴120的线绳固定位置滑动,这样线绳200会从线绳固定位置开始一圈圈地绕在绕线轴120上。
在一些实施例中,为了便于线绳200一圈圈地绕在绕线轴120上,参阅图2、图3,间隙能够容纳一层绕设于绕线轴120的外周面的线绳200。通过对安装壳110、绕线轴120和线绳200设置合适的尺寸,使得在绕线轴120的径向只能绕设一圈线绳200。在绕线轴120的第一端120a至第二端120b的方向,线绳200会从线绳固定位置开始一圈圈地绕在绕线轴120上,而不会引起线绳200的混乱。
为了降低在调节线绳200长度时线绳200的摩擦阻力,可以有不同的实现方式。第一种降低线绳200阻力实现方式是:参阅图5、图6,出线口1112的边缘设置圆角1112a,这样可降低在调节线绳200时线绳200和安装壳110出线口1112内壁之间的摩擦力,便于线绳200在出线口1112处的出入。
第二种降低线绳200阻力实现方式是:参阅图5、图6,安装壳110在靠近出线口1112处设有用于导引线绳200的滚动件140,在调节线绳200过程中,滚动件140和线绳200之间为滚动摩擦,有效降低线绳200的摩擦力,便于调节线绳200。示例性的,滚动件140为转动轴钉,转动轴钉包括固定在安装壳110内的固定轴141和套设在固定轴141外的滚动体142,在调节线绳200时,滚动体142和线绳200接触配合,线绳200带动滚动体142绕固定轴141转动,该结构简单实用。
在安装壳110内出线口1112的两边各设置一个滚动件140时,能调节线绳200相对于安装壳110的出线角度,利于线绳200大致沿着垂直于绕线轴120轴线的方向穿出安装壳110,使得手柄组件100具备相对确定的出线角度,利于提升使用者在跳绳运动时的舒适性。
第三种降低线绳200阻力实现方式是:参阅图3,容纳槽1111的内壁设有锥度,在由绕线轴120的第一端120a至第二端120b的方向容纳槽1111的内壁的内径逐渐变大。在通过转动调节轮130来放线的时候,将容纳槽1111在绕线轴120的第二端120b(即靠近出线口1112的一端)的内径制作的较大,这样可降低线绳200和容纳槽1111内壁之间的摩擦力,便于在转动调节轮130时线绳200的送出。通过增加容纳槽1111内壁的锥度,可降低线绳200和容纳槽1111内壁之间的阻力。
第四种降低线绳200阻力实现方式是:通过增加容纳槽1111内壁的表面光洁度,降低线绳200和容纳槽1111内壁之间的阻力,利于线绳200相对于容纳槽1111内壁滑动。
在一些实施例中,参阅图1至图3,手柄组件100还包括手柄本体170,安装壳110转动安装于手柄本体170,安装壳110的转动轴线和绕线轴120的转动轴线相重合。采用安装壳110相对手柄本体170转动的方式,在跳绳运动时可实现线绳200的快速摇动,线绳200不会打结,使用体验更好。
示例性的,安装壳110具有转轴1114,转轴1114插设在手柄本体170的安装槽171内,并通过轴承172将转轴1114支承在手柄本体170上,这样利于安装壳110平稳地相对手柄本体170转动。
在设置绕线轴和手柄组件时有不同的实现方式。第一种实现方式是:参阅图1至图3,绕线轴120的第一端120a朝向手柄本体170设置,绕线轴120的第二端120b背向手柄本体170设置。即绕线轴120的线绳固定位置(比如绕线轴120的第一端120a)靠近手柄本体170设置,而出线口1112在安装壳110远离手柄本体170的位置。
图7为本申请另一实施例提供的跳绳的立体装配图;图8为图7沿E-E线的局部剖视图;图9为图7沿F-F线的局部剖视图。图7至图9只展示了手柄本体的部分结构。
第二种实现方式是:参阅图7至图9,绕线轴120的第二端120b朝向手柄本体170设置,绕线轴120的第一端120a背向手柄本体170设置。即绕线轴120的线绳固定位置(比如绕线轴120的中部)远离手柄本体170设置,而出线口1112在安装壳110靠近手柄本体170的位置。

在设置安装壳110、绕线轴120和调节轮130时,参阅图2、图3、图10,安装壳110具有盖体112,绕线轴120沿绕线轴120的轴向限位于盖体112;盖体112或绕线轴120设有齿圈114;调节轮130套设于或穿设于绕线轴120的一端,调节轮130能够沿绕线轴120的轴向在第一位置和第二位置间移动;结合图11至图13,当调节轮130在第一位置时,调节轮130的凸齿131和齿圈114相啮合,调节轮130沿周向限位于盖体112;结合图14,当调节轮130在第二位置时,调节轮130的凸齿131和齿圈114相分离,绕线轴120能够相对于盖体112转动。通过沿着绕线轴120的轴向改变调节轮130的位置,即可实现绕线轴120在锁止状态和自由状态之间切换,操作方便。齿圈114具有周向布置的多个齿槽,调节轮130的凸齿131可以和齿圈114的齿槽配合。调节轮130的第一位置和第二位置是确定的,分别是调节轮130的凸齿131和齿圈114相啮合和相分离的位置。参阅图3、图13,在需要限定线绳200长度时,改变调节轮130的轴向位置,将调节轮130的凸齿131和齿圈114相啮合,这样绕线轴120切换至锁止状态,调节轮130和绕线轴120均不能转动,限定了穿出安装壳110的线绳200长度。参阅图14,在需要调节线绳200长度时,改变调节轮130的轴向位置,将调节轮130的凸齿131和齿圈114相分离,这样绕线轴120切换至自由状态绕线轴120可以转动,就能按需调节穿出安装壳110的线绳200长度。
在设置调节轮130的凸齿131时,调节轮130上可设置一个或多个凸齿131。在设置多个凸齿131时,需要满足多个凸齿131和齿圈114的多个齿槽对应啮合,多个凸齿131和齿圈114配合所形成的周向限位效果更好。
齿圈114的齿槽边缘可设置倒角,调节轮130的凸齿131可设置倒角,便于齿圈114的齿槽和凸齿131两者顺利啮合。
在设置安装壳110时,参阅图2、图3,安装壳110包括壳体111和盖体112,盖体112固定在壳体111的开口1113处,壳体111和盖体112围成容纳槽1111,这种安装壳110容易加工和装配,便于在安装壳110上安装绕线轴120等零件。盖体112可通过螺钉、卡扣或其它机械方式固定在壳体111上。
图15为图10的绕线轴、销钉、盖体和调节轮的立体装配图;图16为图1沿C-C线的局部剖视图。
在一些实施例中,为了实现调节轮130可沿绕线轴120的轴向移动,以及在绕线 轴120处于自由状态时调节轮130和绕线轴120能够相对于盖体112同步转动,参阅图3,齿圈114设于盖体112上且与盖体112的过孔1122同轴设置,绕线轴120穿设于过孔1122能够相对盖体112转动,结合图10、图15、图16,绕线轴120和调节轮130之间通过销钉151连接,销钉151沿绕线轴120的径向安装在绕线轴120上,调节轮130具有沿调节轮130的轴线延伸的导向槽132,销钉151的端部可滑动地安装于导向槽132。在装配绕线轴120时,绕线轴120穿过盖体112的过孔1122,绕线轴120的外周面和过孔1122配合,使绕线轴120可相对盖体112转动。结合图14,在绕线轴120切换至自由状态并且调节轮130转动时,调节轮130通过销钉151带动绕线轴120转动,实现两者相对盖体112同步转动。在改变调节轮130的轴向位置时,由于绕线轴120已被限定轴向位置,通过安装在绕线轴120的销钉151和调节轮130的导向槽132配合来限定调节轮130的移动范围,使得调节轮130能够沿绕线轴120的轴向在第一位置和第二位置间移动。调节轮130的第一位置和第二位置的间距就是导向槽132的长度。
在设置盖体112和齿圈114时,盖体112和齿圈114可以为一体成型结构或组装结构。采用组装时,盖体112和齿圈114之间可通过紧固件或其它方式连接。齿圈114可以为内齿圈、外齿圈或端面齿圈,凸齿131设置为能够和齿圈114的齿槽相啮合的形状。
在对绕线轴120轴向限位时,参阅图14,绕线轴120的一端插在安装壳110的容纳槽1111内,通过容纳槽1111的内壁去限位。参阅图8,绕线轴120插在安装壳110内的一端可以支承在安装壳110的内壁,安装壳110内可设置套筒113来支承绕线轴120的端部。参阅图8、图14,绕线轴120的中部外周面设有台阶面121,绕线轴120的台阶面121和盖体112的内壁抵接,这样限定了绕线轴120的轴向位置,使绕线轴120转动过程中在轴向保持在预定位置。
在装配绕线轴120、销钉151和调节轮130时,调节轮130套设在绕线轴120伸出安装壳110的一端外部。绕线轴120伸出安装壳110的一端设有径向延伸的第一安装孔122,销钉151穿过该第一安装孔122且销钉151的两端伸出绕线轴120外。调节轮130具有两个相对设置导向槽132,导向槽132的长度方向和绕线轴120的轴线相互平行,销钉151的两端一一对应地可滑动地安装于调节轮130的两个导向槽132,这样就能实现调节轮130相对绕线轴120的轴向移动并限定调节轮130的移动范围,还能使调节轮130和绕线轴120相对盖体112同步转动。此外,使销钉151的一端伸出绕线轴120外部,调节轮130配置一个导向槽132,销钉151的一端可滑动地安装于该导向槽132,这样也能实现同样的功能。
其中,销钉151可以为柱体销钉或者弹性销钉。参阅图10、图16,采用柱体销钉151a时,柱体销钉151a直接安装至绕线轴120的第一安装孔122即可。参阅图9,采用弹性销钉151b时,弹性销钉151b包括弹性件1511和分别设于弹性件1511的两个端部的抵接端子1512,在弹性件1511的作用下,两个抵接端子1512可以伸缩设置于第一安装孔122,两个抵接端子1512作为销钉的两端和调节轮130的两个导向槽132一一对应配合。
参阅图7至图9,对于采用销钉151连接绕线轴120和调节轮130的手柄组件100, 将绕线轴120的第二端120b朝向手柄本体170设置,绕线轴120的第一端120a背向手柄本体170设置,调节轮130可以套设在安装壳110外,这样调节轮130、安装壳110和绕线轴120在部分区域重叠,在安装壳110和调节轮130具有一定总长度的情况下,调节轮130的外周面具有较大面积,便于对调节轮130进行操作。
在一些实施例中,为了调节轮130能保持在第一位置或第二位置,参阅图3,调节轮130的外周面设有弹性端子152,调节轮130的内周面间隔设置有第一凹槽133和第二凹槽134。结合图13,当调节轮130在第一位置时,弹性端子152抵设于第一凹槽133,以限定调节轮130的轴向位置使得凸齿131和齿圈114保持相啮合,限定线绳200伸出安装壳110的长度。结合图14,当调节轮130在第二位置时,弹性端子152抵设于第二凹槽134,以限定调节轮130的轴向位置使得凸齿131和齿圈114保持相分离,有效降低收线或放线过程中凸齿131进入齿圈114的可能性。弹性端子152和两个凹槽的分别配合就能将调节轮130限位在绕线轴120的两个预定位置。在受外力时弹性端子152会压缩蓄能,在外力减少时弹性端子152会释能伸出。在需要改变调节轮130相对绕线轴120的轴向位置时,原来的弹性端子152抵设在其中一个凹槽处,拉拔调节轮130以后,弹性端子152受到调节轮130内周面的作用力内缩,直到弹性端子152和调节轮130的另一个凹槽对齐,弹性端子152才会伸出抵设在另一个凹槽处,实现另一个位置的定位。
示例性的,参阅图3、图10,绕线轴120伸出安装壳110的一端设有沿径向贯穿绕线轴120的第二安装孔123,弹性端子152包括弹性件1521和设于弹性件1521的两端的两个抵接端子1522,弹性件1521和两个抵接端子1522放置在第二安装孔123内,调节轮130的内周面配置两组相对设置的第一凹槽133和第二凹槽134,以和两个抵接端子1522适配,这样能有效地对调节轮130的轴向位置进行限定。其中,弹性件1521可以为伸缩弹簧。
在另一实施例中,参阅图8,第二安装孔123可以是盲孔,按需在绕线轴120上配置一个或多个第二安装孔123,并在各个第二安装孔123装配相同数量的弹性件1521和抵接端子1522,并在调节轮130内周面设置相应数量的第一凹槽133和第二凹槽134,这样也能实现调节轮130的轴向限位。

在一些实施例中,为了实现调节轮130可沿绕线轴120的轴向移动,以及在绕线轴120处于自由状态时调节轮130和绕线轴120能够相对于盖体112同步转动,参阅图17至图22,齿圈114设于盖体112上且与盖体112的过孔1122同轴设置,调节轮130穿设于过孔1122,结合图23,绕线轴120具有沿调节轮130的轴线延伸的限位槽124,凸齿131可滑动地安装于限位槽124,使得调节轮130能够沿绕线轴120的轴向在第一位置和第二位置间移动。齿圈114可以为内齿圈,凸齿131设置为能够和齿圈 114的齿槽相啮合的形状。绕线轴120的限位槽124和齿圈114的一个齿槽的横截面形状是相同的,且两者均沿绕线轴120的轴线延伸,这样调节轮130的凸齿131可以在齿圈114的一个齿槽和限位槽124内滑动,以使调节轮130可沿绕线轴120的轴向移动。盖体112和齿圈114可以为一体成型结构或组装结构。在采用组装时,盖体112和齿圈114之间可通过紧固件或其它方式连接。参阅图20、图23、图24,当调节轮130的凸齿131滑动至限位槽124和齿圈114的一个齿槽时,即凸齿131同时和限位槽124、齿圈114的一个齿槽啮合,调节轮130移动至第一位置,实现调节轮130和绕线轴120周向限位在盖体112上而不能转动。参阅图25,通过向内推调节轮130至第二位置,使得调节轮130的凸齿131滑动至限位槽124,凸齿131和限位槽124保持啮合,而凸齿131分离齿圈114,这样就能转动调节轮130并带动绕线轴120转动,使调节轮130和绕线轴120能够相对于盖体112同步转动。在设置限位槽124时,限位槽124和凸齿131的数量和位置对应设置。在配置多组限位槽124和凸齿131时,便于调节轮130带动绕线轴120转动。
在对绕线轴120轴向限位时,参阅图20,绕线轴120的一端插在安装壳110的容纳槽1111内,绕线轴120通过容纳槽1111的内壁去限位;绕线轴120插在容纳槽1111内的一端可以支承在安装壳110的内壁,安装壳110内可设置套筒113来支承绕线轴120的端部。绕线轴120另一端和盖体112的内壁抵接,这样限定了绕线轴120的轴向位置,使绕线轴120转动过程中在轴向保持在预定位置。
在一些实施例中,为了便于调节轮130沿绕线轴120的轴向移动,参阅图18、图20,盖体112活动安装有按键161,调节轮130和绕线轴120之间设有第一弹性件162。通过在调节轮130和绕线轴120之间设置第一弹性件162,使得被按压后的调节轮130在松开后具有复位的能力,这样操作性更好。结合图20,当按键161未按下时,在第一弹性件162的弹性力下,调节轮130处于第一位置,调节轮130的凸齿131从绕线轴120的限位槽124弹出一部分和齿圈114啮合,实现调节轮130和绕线轴120周向限位在盖体112上而不能转动,即绕线轴120处于锁止状态,穿出安装壳110的线绳200长度被固定。调节轮130抵设于按键161,使按键161弹起状态。结合图25,当按键161被按下时,按键161抵设于调节轮130以推动调节轮130,调节轮130切换至第二位置,调节轮130的凸齿131和绕线轴120的限位槽124保持啮合,而凸齿131分离齿圈114,使调节轮130和绕线轴120能够相对于盖体112同步转动,即绕线轴120处于自由状态,第一弹性件162被压缩。其中,按键可为按键帽。调节轮130可设置骨位135,用于和按键161抵接。第一弹性件162可以为压缩弹簧。可以配置一个或多个第一弹性件162,以改变作用在调节轮130上的弹性力。
在装配第一弹性件162时,有不同的实现方式。第一种实现方式是:参阅图20、图23、图26、图27,调节轮130具有定位柱136,定位柱136的端部可滑动地安装于绕线轴120的定位槽126;第一弹性件162套设于定位柱136外,第一弹性件162的两端分别抵设于绕线轴120和调节轮130。这样可限定第一弹性件162的位置。通过定位柱136和定位槽126的配合,可以将绕线轴120更稳定地支撑在调节轮130上。在配置多个第一弹性件162时,调节轮130设置多个定位柱136,绕线轴120设置多个定位槽126,第一弹性件162一一对应地套设在定位柱136外,定位柱136和定位 槽126一一对应配置。
第二种实现方式是:绕线轴120具有定位槽126,第一弹性件162的两端分别抵设于定位槽126的底面和调节轮130。这样容易装配第一弹性件162,可限定第一弹性件162的位置。在配置多个第一弹性件162时,绕线轴120设置多个定位槽126,第一弹性件162一一对应地设在定位槽126。
在一些实施例中,为了提升线绳200卷绕在绕线轴120上的便利性,参阅图18、图20,按键161和调节轮130之间通过弹性扭转件163连接,弹性扭转件163用于在按键161被按下时对绕线轴120提供扭力,以使绕线轴120转动而线绳200自动绕设于绕线轴120的外周面。通过在按键161和调节轮130之间设置弹性扭转件163,并使弹性扭转件163朝向一个预定方向扭转以蓄能,在弹性扭转件163朝向反向扭转时将会释能,带动绕线轴120进行多圈的转动复位,使绕在绕线轴120上的线绳200具有一个内缩力,线绳200可以自动向安装壳110内部收缩并绕在绕线轴120外。在操作时,结合图25,先要按下按键161,使调节轮130的凸齿131和盖体112上的齿圈114相分离,即调节轮130切换至自由状态,此时可进行线绳200有效长度的调节,第一弹性件162压缩蓄能。在需要放线时,将线绳200由安装壳110内拉出,使穿出安装壳110的线绳200长度增加,绕线轴120转动带动弹性扭转件163卷动收紧以蓄能。结合图20,在调节好线绳200有效长度后需要固定线绳200时,松开按键161,在第一弹性件162的作用下,调节轮130复位至锁止状态,调节轮130的凸齿131和盖体112的齿圈114相啮合,调节轮130和绕线轴120不能继续转动,限定了穿出安装壳110的线绳200长度。在需要收线时,不用牵拉线绳200,弹性扭转件163会释能以驱动绕线轴120转动,绕线轴120的线绳固定位置已绕设有一部分线绳200,线绳200将会由外部经过安装壳110的出线口1112进入安装壳110内,并且一圈圈地绕在绕线轴120外部。在配置有弹性扭转件163后,收放线操作更简单。其中,弹性扭转件163可以为发条弹簧,就是螺旋线在一个平面内的弹簧,可提供一定扭力。
图28为图18的跳绳中的弹性扭转件和按键的立体装配图;图29为图18的跳绳中的弹性扭转件和调节轮的立体装配图。
在安装弹性扭转件163时,参阅图28、图29,弹性扭转件163和绕线轴120没有重叠分布,使安装壳110整体直径可以做的较小,和手柄本体170的直径相等或接近,而不会有突兀感。弹性扭转件163可以设置在按键161内,这样结构紧凑。弹性扭转件163的外端163b固定在按键161上,而内端163a固定在调节轮130上。示例性的,按键161的内壁设有凸起1613和骨位1612,弹性扭转件163的外端163b被凸起1613阻挡以限定轴向位置,通过按键161的内壁和骨位1612限定该外端163b的径向位置。或者,按键161的内壁设有骨位1612,弹性扭转件163的外端163b绕设固定在骨位1612上。调节轮130设置骨位135,骨位135可以为具有卡槽的柱状体,弹性扭转件163的内端163a穿设于卡槽后并相对柱状体弯折设置。结合图25,在按下按键161时,按键161推动该骨位135以带动调节轮130移动,以使调节轮130的凸齿131滑动至调节轮130的导向槽132。
此外,弹性扭转件的外端固定在调节轮上,而内端固定在按键上,并且更换另一旋转方向的弹性扭转件,也是可行的。
对于具有按键161、第一弹性件162和弹性扭转件163的手柄组件100,跳绳配置两个手柄组件100,如果使用者双手各抓住一个手柄组件100,用脚踩着线绳200的中部,可以同时调节两个手柄组件100的线绳200伸出长度,拉动线绳200则向外出绳,松开线绳200则在弹性扭转件163的扭力作用下线绳200回缩至安装壳110内,操作很方便。
图30为图18的跳绳中的盖体和按键的立体装配图。
在一些实施例中,为了限定按键161的移动范围,参阅图25至图27、图30,盖体112具有沿调节轮130的轴线延伸的导引槽1123,按键161的扣位1611可滑动地安装于导引槽1123,导引槽1123的端部设有阻挡壁1124以限定按键161的移动范围。通过盖体112的导引槽1123和按键161的扣位1611,限定了按键161相对盖体112直线移动而不能转动,通过盖体112的阻挡壁1124限位按键161的移动范围,降低按键161在移动过程中脱离盖体112的可能性。
在设置按键161的扣位1611时,扣位1611可以设置一个或多个。扣位1611可以是弹性扣位,便于将按键161从外侧压入盖体112内。扣位1611还可以是固定扣位。此外,按键161的边缘可设置翻边1614,当翻边1614抵接于盖体112的内壁时将按键161限位在盖体112上。
在另一实施例中,齿圈114设于盖体112上且与盖体112的过孔1122同轴设置,调节轮130穿设于过孔1122,绕线轴120具有沿调节轮130的轴线延伸的限位槽124,凸齿131可滑动地安装于限位槽124,使得调节轮130能够沿绕线轴120的轴向在第一位置和第二位置间移动。安装壳外套设有具有过线口的筒状壳,并且筒状壳活动安装有按键,调节轮和绕线轴之间设有第一弹性件。通过在调节轮和绕线轴之间设置第一弹性件,使得被按压后的调节轮在松开后具有复位的能力,这样操作性更好。当按键未按下时,在第一弹性件的弹性力下,调节轮处于第一位置,调节轮抵设于按键;当按键被按下时,按键抵设于调节轮,调节轮切换至第二位置,第一弹性件被压缩。在按压或松开按键时,调节轮可沿绕线轴的轴向移动。
其中,筒状壳可设置为合适的造型,比如圆台状或其它形状,以改善外观。筒状壳可通过紧固件或其它方式固定在安装壳外部。筒状壳的过线口和安装壳的出线口相连通,使得线绳可经过出线口和过线口穿出筒状壳外。按键活动安装在筒状壳的一端口处。
在筒状壳活动安装有按键的情况下,关于第一弹性件的装配方式,盖体和轴部之间通过弹性扭转件连接,可参考如图18至图20所示盖体活动安装有按键的实施例。
为了限定按键的移动范围,筒状壳具有沿调节轮的轴线延伸的导引槽,按键的扣位可滑动地安装于导引槽,导引槽的端部设有阻挡壁以限定按键的移动范围。通过筒状壳的导引槽和按键的扣位,限定了按键相对筒状壳直线移动而不能转动,通过筒状壳的阻挡壁限位按键的移动范围,降低按键在移动过程中脱离筒状壳的可能性。

在一些实施例中,为了实现调节轮130可沿绕线轴120的轴向移动,以及在绕线 轴120处于自由状态时绕线轴120能够相对于盖体112转动,参阅图31至图34,齿圈114设于绕线轴120上并位于容纳槽1111内且与盖体112的过孔1122同轴设置,绕线轴120包括用于供线绳200绕设的绕线部128以及同轴连接于绕线部128的轴部129,绕线部128位于容纳槽1111内,轴部129穿设于调节轮130并能够相对调节轮130转动;调节轮130沿绕线轴120的轴向可滑动地安装于过孔1122处,凸齿131设于调节轮130靠近绕线部128的一端并位于容纳槽1111内。绕线轴120中的轴部129穿过调节轮130,调节轮130沿轴向滑动安装在盖体112的过孔1122处,使得调节轮130能够沿绕线轴120的轴向在第一位置和第二位置间移动。在绕线轴120处于自由状态时,绕线轴120和齿圈114能够相对于盖体112同步转动。在绕线轴120中,绕线部128的外径可以比轴部129的外径大,在同样轴向长度下,大外径的绕线部128可绕设更多线绳200。
在设置绕线轴120和齿圈114时,齿圈114可以设置在绕线轴120中的绕线部128上。参阅图35,绕线部128和齿圈114之间可通过紧固件或卡扣1141或其它方式连接。齿圈114可以为内齿圈、外齿圈或端面齿圈,而凸齿131设置为能够和齿圈114相啮合的形状。
在齿圈114为端面齿圈时,参阅图34,绕线部128靠近轴部129的一侧设有环形槽1281,绕线部128形成有与轴部129同轴的环状部1282。端面齿圈朝向环形槽1281的底面设置,端面齿圈安装于环状部1282。调节轮130的凸齿131为能够和端面齿圈啮合的端面齿,设于环形槽1281内。通过改变调节轮130的轴向位置,使得调节轮130的凸齿131和端面齿圈相啮合或分离。这种结构容易成型和装配。端面齿圈和调节轮130的凸齿131可以为斜齿或其它齿形。
在对绕线轴120轴向限位时,绕线轴120的绕线部128插在安装壳110的容纳槽1111内,通过容纳槽1111的内壁去限位。绕线部128可以支承在安装壳110的内壁,安装壳110内可设置套筒113来支承绕线轴120的端部。齿圈114设于绕线部128上,齿圈114和盖体112的内壁抵接,这样限定了绕线轴120的轴向位置,使绕线轴120转动过程中在轴向保持在预定位置。
在设置盖体112时,参阅图32至图34,盖体112可以包括框状部112a和隔板部112b,隔板部112b可采用紧固件或其它方式安装在框状部112a内,过孔1122设于隔板部112b,框状部112a安装在壳体111的开口1113处,这种方式容易成型和装配。此外,框状部112a和隔板部112b还可以为一体成型结构。
图36为图32的跳绳中的调节轮、齿圈、部分盖体和浮动件的立体分解图。
在装配调节轮130和盖体112时,参阅图34、图36,盖体112的过孔1122内壁和调节轮130之间可以设置导向结构,用于导引调节轮130沿预定直线滑动安装于盖体112的过孔1122处,而不能相对盖体112转动。比如,在过孔1122内壁设凸块1122a,在调节轮130的外周设置沿调节轮130的轴向延伸的滑动槽137,凸块1122a滑动安装于滑动槽137以导引调节轮130在预定直线上移动。此外,在调节轮130的外周设凸块,在过孔1122内壁设滑动槽,也能实现对调节轮130的导向。
在一些实施例中,为了便于调节轮130沿绕线轴120的轴向移动,参阅图31至图34,盖体112活动安装有按键161,调节轮130远离绕线部128的一端连接有浮动件 164,浮动件164位于容纳槽1111外,浮动件164和盖体112之间设有第二弹性件165。通过在调节轮130穿出盖体112的一端连接浮动件164,并在浮动件164和盖体112之间设有第二弹性件165,使得被按压后的调节轮130在松开后具有复位的能力,这样操作性更好。当按键161未按下时,在第二弹性件165的弹性力下,调节轮130处于第一位置,调节轮130的凸齿131和绕线轴120上的齿圈114啮合,调节轮130已周向限位在盖体112上,从而实现绕线轴120周向限位在盖体112上而不能转动,即绕线轴120处于锁止状态,穿出安装壳110的线绳200长度被固定。浮动件164抵设于按键161,使按键161弹起状态。当按键161被按下时,按键161抵设于浮动件164以推动浮动件164,调节轮130跟随浮动件164移动,调节轮130切换至第二位置,调节轮130的凸齿131分离齿圈114,使绕线轴120能够相对于盖体112转动,即绕线轴120处于自由状态,第二弹性件165被压缩。其中,按键161可为按键帽。第二弹性件165可以为压缩弹簧。可以配置一个或多个第二弹性件165,以改变作用在浮动件164上的弹性力。浮动件164可以为片状,结构紧凑。浮动件164设有供轴部129穿过的通孔,可将浮动件164做的较大,以便于设置多个第二弹性件165。
在装配第二弹性件165时,参阅图32、图33,浮动件164具有限位柱1641,盖体112具有限位孔1126,第二弹性件165的一端套设于限位柱1641并抵设于浮动件164,第二弹性件165的另一端插设于限位孔1126。这样容易装配第二弹性件165,可限定第二弹性件165的位置。此外,浮动件设置限位孔,浮动件设置限位柱,也方便第二弹性件的定位装配。
图37为图32的跳绳中的弹性扭转件、部分盖体和绕线轴的立体装配图。
在一些实施例中,为了提升线绳200卷绕在绕线轴120上的便利性,参阅图32、图34、图37,盖体112和轴部129之间通过弹性扭转件163连接,弹性扭转件163用于在按键161被按下时对轴部129提供扭力,以使轴部129转动而线绳200自动绕设于绕线部128。通过在盖体112和轴部129之间设置弹性扭转件163,并使弹性扭转件163朝向一个预定方向扭转以蓄能,在弹性扭转件163朝向反向扭转时将会释能,带动绕线轴120进行多圈的转动复位,使绕在绕线轴120上的线绳200具有一个内缩力,线绳200可以自动向安装壳110内部收缩并绕在绕线部128外。在操作时,先要按下按键161,使调节轮130的凸齿131和绕线轴120上的齿圈114相分离,即调节轮130切换至自由状态,此时可进行线绳200有效长度的调节,第二弹性件165压缩蓄能。在需要放线时,将线绳200由安装壳110内拉出,使穿出安装壳110的线绳200长度增加,绕线轴120转动带动弹性扭转件163卷动收紧以蓄能。在调节好线绳200有效长度后需要固定线绳200时,松开按键161,在第二弹性件165的作用下,调节轮130复位至锁止状态,调节轮130的凸齿131和齿圈114相啮合,绕线轴120不能继续转动,限定了穿出安装壳110的线绳200长度。在需要收线时,不用牵拉线绳200,弹性扭转件163会释能以驱动绕线轴120转动,绕线轴120的线绳固定位置已绕设有一部分线绳200,线绳200将会由外部经过安装壳110的出线口1112进入安装壳110内,并且一圈圈地绕在绕线轴120外部。在配置有弹性扭转件163后,收放线操作更简单。
在一些实施例中,为了便于弹性扭转件163的安装和保护,参阅图32、图34、图 37,盖体112具有筒状部1125,浮动件164可滑动地安装于筒状部1125内,按键161套设于筒状部1125的外周;轴部129远离绕线部128的一端位于筒状部1125内,弹性扭转件163位于筒状部1125内,弹性扭转件163的内端163a连接于轴部129远离绕线部128的一端,弹性扭转件163的外端163b连接于筒状部1125。将弹性扭转件163设于筒状部1125内,而按键161套设于筒状部1125的外周,充分利用径向空间使得手柄组件100的轴向尺寸较小。
在安装弹性扭转件163时,参阅图37,弹性扭转件163的两端可设为U字弯折结构,用于固定和承受拉力。筒状部1125的外壁设有卡槽1125b、骨位1125c和凸起1125d,弹性扭转件163的外端163b穿过卡槽1125b后弯折设置,弯折的外端163b设在筒状部1125的外壁和骨位1125c之间以限定径向位置,弯折的外端163b被凸起1125d阻挡以限定轴向位置。轴部129的端部设有卡槽1291,弹性扭转件163的内端163a穿设于卡槽1291后并相对轴部129弯折设置。实现弹性扭转件163两个端部的可靠连接。
对于具有按键161、浮动件164、第二弹性件165和弹性扭转件163的手柄组件100,跳绳配置两个手柄组件100,如果使用者双手各抓住一个手柄组件100,用脚踩着线绳200的中部,可以同时调节两个手柄组件100的线绳200伸出长度,拉动线绳200则向外出绳,松开线绳200则在弹性扭转件163的扭力作用下线绳200回缩至安装壳110内,操作很方便。
在一些实施例中,参阅图36、图37,筒状部1125具有沿调节轮130的轴向延伸的引导槽1125a,浮动件164具有引导部1642,引导部1642穿设于引导槽1125a并可滑动地安装于引导槽1125a,结合图33,引导部1642穿出筒状部1125外的部分和按键161相抵接。筒状部1125的引导槽1125a和浮动件164的引导部1642配合,使浮动件164能够沿调节轮130的轴向稳定移动。并且按键161的边缘和浮动件164的引导部1642能够抵接配合,在按下或松开按键161时按键161和浮动件164可以相互推动。按键161的边缘可设置凹位1615,引导部1642穿出筒状部1125外的部分和凹位1615的底面抵接,这样可使浮动件164和按键161之间可靠抵接。筒状部1125可设置多个引导槽1125a,浮动件164可设置多个引导部1642,多个引导部1642和多个引导槽1125a配合,使浮动件164更稳定地沿轴向移动。
在一些实施例中,为了限定按键161的移动范围,参阅图32、图33,盖体112具有沿调节轮130的轴线延伸的导引槽1123,按键161的扣位1611可滑动地安装于导引槽1123,导引槽1123的端部设有阻挡壁1124以限定按键161的移动范围。通过盖体112的导引槽1123和按键161的扣位1611,限定了按键161相对盖体112直线移动而不能转动,通过盖体112的阻挡壁1124限位按键161的移动范围,降低按键161在移动过程中脱离盖体112的可能性。
在设置按键161的扣位1611时,扣位1611可以设置一个或多个。扣位1611可以是弹性扣位,便于将按键161从外侧压入盖体112内。扣位1611还可以是固定扣位。此外,按键161的边缘可设置翻边1614,当翻边1614抵接于盖体112的内壁时将按键161限位在盖体112上。
图42为本申请另一实施例提供的跳绳的局部剖视图;图43为图42的跳绳的立体分解图。在另一实施例中,参阅图42、图43,齿圈114设于绕线轴120上并位于容纳 槽1111内且与盖体112的过孔1122同轴设置,绕线轴120包括用于供线绳200绕设的绕线部128以及同轴连接于绕线部128的轴部129,绕线部128位于容纳槽1111内,轴部129穿设于调节轮130并能够相对调节轮130转动;调节轮130沿绕线轴120的轴向可滑动地安装于过孔1122处,凸齿131设于调节轮130靠近绕线部128的一端并位于容纳槽1111内。安装壳110外套设有具有过线口1151的筒状壳115,并且筒状壳115活动安装有按键161,调节轮130远离绕线部128的一端连接有浮动件164,浮动件164位于容纳槽1111外,浮动件164和盖体112之间设有第二弹性件165。通过在调节轮130穿出盖体112的一端连接浮动件164,并在浮动件164和盖体112之间设有第二弹性件165,使得被按压后的调节轮130在松开后具有复位的能力,这样操作性更好。当按键161未按下时,在第二弹性件165的弹性力下,调节轮130处于第一位置,调节轮130的凸齿131和绕线轴120上的齿圈114啮合,调节轮130已周向限位在盖体112上,从而实现绕线轴120周向限位在盖体112上而不能转动,即绕线轴120处于锁止状态,穿出安装壳110的线绳200长度被固定。浮动件164抵设于按键161,使按键161弹起状态。当按键161被按下时,按键161抵设于浮动件164以推动浮动件164,调节轮130跟随浮动件164移动,调节轮130切换至第二位置,调节轮130的凸齿131分离齿圈114,使绕线轴120能够相对于盖体112转动,即绕线轴120处于自由状态,第二弹性件165被压缩。在按压或松开按键161时,调节轮130可沿绕线轴120的轴向移动。
其中,筒状壳115可设置为合适的造型,比如圆台状或其它形状,以改善外观。筒状壳115可通过紧固件或其它方式固定在安装壳110外部。筒状壳115的过线口1151和安装壳110的出线口1112相连通,使得线绳200可经过出线口1112和过线口1151穿出筒状壳115外。按键161可为按键帽,按键161活动安装在筒状壳115的一端口处。第二弹性件165可以为压缩弹簧。可以配置一个或多个第二弹性件165,以改变作用在浮动件164上的弹性力。浮动件164可以为片状,结构紧凑。
在筒状壳115活动安装有按键161的情况下,关于第二弹性件165的装配方式,盖体112和轴部129之间通过弹性扭转件163连接,在盖体112具有筒状部1125时浮动件164、筒状部1125、轴部129和弹性扭转件163的装配关系,弹性扭转件163的具体结构,筒状部1125的引导槽1125a、浮动件164的引导部1642和按键161的装配关系,可参考如图31至图34所示盖体112活动安装有按键161的实施例。
参阅图42、图43,为了限定按键161的移动范围,筒状壳115具有沿调节轮130的轴线延伸的导引槽1152,按键161的扣位1611可滑动地安装于导引槽1152,导引槽1152的端部设有阻挡壁1153以限定按键161的移动范围。通过筒状壳115的导引槽1152和按键161的扣位1611,限定了按键161相对筒状壳115直线移动而不能转动,通过筒状壳115的阻挡壁1153限位按键161的移动范围,降低按键161在移动过程中脱离筒状壳115的可能性。
在连接线绳200和绕线轴120时有不同的实现方式。第一种实现方式是:参阅图2、图3,绕线轴120的内孔125处安装有卡线塞子180,卡线塞子180用于固定线绳200的一端部,便于将线绳200的端部稳固地装配在绕线轴120上,在需要更换时也方便将线绳200在绕线轴120上取下。示例性的,线绳200的一端部穿过卡线塞子180 的固定孔181,卡线塞子180塞进绕线轴120内,卡线塞子180和绕线轴120内孔125之间可以采用过盈装配或卡扣等连接方式。
第二种实现方式是:参阅图22、图24,绕线轴120能够直接固定线绳200的一端部。这样可简化绕线轴120的结构,容易制作和装配。示例性的,绕线轴120具有至少两个沿径向延伸的通孔127,线绳200的一端部穿过其中一个通孔127后弯折穿过另外一个通孔127,就能将线绳200可靠地固定在绕线轴120上。
