Description

便捷快速调节重量的多功能哑铃 技术领域
本发明属于健身器材领域，具体涉及一种便捷快速调节重量的多功能哑铃。
背景技术
哑铃是一种锻炼和健身练习的最普遍的辅助器材，其结构简单，使用方便，可用于康复，增肌和力量的锻炼和训练。使用者为适应不同重量及项目的锻炼需要，需要购买很多不同重量规格的哑铃、杠铃、壶铃，健身球等器材设备，既需要占用较大空间存放，又造成经济和资源的极大浪费。现有的可调节重量哑铃在使用锻炼的过程中，通过在哑铃手柄的两端套上重量不等的铃平来增减重量，但其需要繁琐拆卸安装的过程，不便于快速更换重量，且还需人工计算使用中的哑铃重量，不便于使用；且现有的哑铃只有单个中间手柄，只能单手使用，功能单一；同时，使用者克服哑铃重量的力矩是不可以改变的，导致训练项目单一枯燥，同时单手握抓哑铃锻炼时，存在扭伤手腕和脱手伤人的安全隐患。
发明内容
本发明的目的在于克服上述局限，提供一种通过特殊的多手柄结构和按钮结构便捷快速地调节哑铃负重，无需人工计算重量，操作简单便于使用的便捷快速调节重量的多功能哑铃。
本发明的目的通过以下技术方案来实现：一种便捷快速调节重量的多功能哑铃，包括中间手柄，中间手柄两侧均连接增减重量的铃片座，铃片座之间还连接有三个边手柄，三个边手柄均匀排布在中间手柄外侧，铃片座的外侧有手柄，铃片座内设有多个配重铃片，配重铃片两侧位于铃片座两边的第一卡槽内，且配重铃片的中心套在铃片座的中轴上，铃片座中轴上设有重量调节装置，重量调节装置位于铃片中部的凹槽内，重量调节装置上部设有 按钮、侧部设有锁舌卡块，锁舌卡块位于凹槽的内侧壁槽内，按钮和锁舌卡块分别位于重量调节装置上部和侧部的通孔处，配重铃片放置于基座的第二卡槽和第三卡槽内。
优选的是，按钮与尾部带有锯齿口的推转凸轮相连，旋转凸轮与推转凸轮及外部套筒部上的调节高度止位凹槽配合，套筒部上设有通孔部及限位卡槽，旋转凸轮与锥形凸台杆相连，锥形凸台杆置于两个锁舌卡块之间，且锁舌卡块朝向锥形凸台杆的一侧设有锥形凹槽，锥形凸台杆的下端设有第二弹簧，锁舌卡块下方连接有第一弹簧。
优选的是，推转凸轮底端有锯齿状第一斜面和第一凸出面，旋转凸轮的中部设有锯齿状第二斜面和第二凸出面，套筒部内设的调节高度止位凹槽与第一凸出面和第二凸出面配合滑动。
优选的是，铃片座外边部挡板上开设扇形槽，形成锻炼手柄。
优选的是，铃片座外边部挡板上设有显示屏用于显示按钮按下的数量并显示计算出使用中的哑铃总重量、运动的时间、速度、次数及能量的消耗数值。
优选的是，重量调节装置顶部设有安全卡锁，安全卡锁位于按钮的一侧。
综上所述，本发明具有以下优点：1、通过按钮的结构可快速调节哑铃负重的训练重量，并通过显示屏直观反映，无需人工计算重量，操作简单便于使用，一个产品能满足不同锻炼重量要求，减少了器材的存放空间，避免经济和资源的浪费；2、当单手握抓中间手柄锻炼时，手腕弯曲到十度左右时，边手柄会与手臂的内侧或外侧接触从而阻挡手腕的进一步弯曲，预防手腕扭伤；3、当单手握抓任何一个边手柄时，相邻的另外两个边手柄也会与手臂的内侧或外侧接触支撑，从而避免手腕的扭伤；4、可以双手握抓任意两个边手柄锻炼，减少了单手握抓哑铃脱手伤人的安全隐患，同时也可以在锻炼过程中单双手的快速连贯切换；5、铃片座两端分别增加了一个手握柄，这样在哑 铃上就有六个手柄，大大增加了使用者手握哑铃的方式，使用者克服哑铃重量的力矩也有了更多选择；6、当单手握抓中间手柄时该产品具有了哑铃的锻炼功效；当单手握抓中间任意一个边手柄时，该产品具有壶铃球的锻炼功效；当双手握抓两边外侧挡板上的手柄时，该产品具有了杠铃的功能，可使训练多样化，不用重复更换锻炼的器材。

具体实施方式
为了加深对本发明的理解，下面将结合实施例和附图对本发明作进一步详述，该实施例仅用于解释本发明，并不构成对本发明保护范围的限定。
实施例1：如图1、4、8所示，本发明提供一种便捷快速调节重量的多 功能哑铃，包括中间手柄1，中间手柄1两侧均连接有铃片座2，铃片座2之间还连接有三个边手柄3，三个边手柄3均匀排布在中间手柄1外侧，三个边手柄3同一水平截面的中心点连线为一个等边三角形，当单手握抓中间手柄1锻炼时，手腕弯曲到十度左右时，边手柄3会与手臂的内侧或外侧接触从而阻挡手腕的进一步弯曲，预防手腕扭伤；当单手握抓任何一个边手柄3时，相邻的另外两个边手柄3也会与手臂的内测或外侧接触支撑，从而避免手腕的扭伤；可以双手握抓任意两个边手柄3锻炼，从而能达到在锻炼过程中单双手的快速连贯切换，达到多种锻炼目的；铃片座2内设有多个配重铃片5，配重铃片5两侧位于铃片座2两边的第一卡槽6内，且配重铃片5的中心套在铃片座2的中轴上，铃片座2中轴上设有重量调节装置7，重量调节装置7位于配重铃片5中部的凹槽8内，重量调节装置7上部设有按钮9、侧部设有锁舌卡块10，锁舌卡块10位于凹槽8的内侧壁槽11内，按钮9和锁舌卡块10分别位于重量调节装置7上部和侧部的通孔处，通过按动按钮9可以使锁舌卡块10伸出来勾住内侧壁槽11，使得配重铃片5被选定，再次按动按钮9可使锁舌卡块10回弹，取消对应选定的配重铃片5，配重铃片5放置于基座的第二卡槽12和第三卡槽13内。
实施例2公开了一种按钮9与锁舌卡块10配合运动的方式：如图6、7所示，按钮9安装在推转凸轮14上，推转凸轮14端部设有锯齿形第一斜面24和第一凸出面25，锯齿形第一斜面24与下方的旋转凸轮15上的第二斜面26配合，推转凸轮14上的第一凸出面25及旋转凸轮15上的第二凸出面27又与套筒部19上的调节高度止位凹槽20及第三斜面28相互配合，调节高度止位凹槽20包括浅位凹槽和深位凹槽，达到上下移动旋转凸轮15的同时，旋转凸轮15又能在旋转中高低位置位依次轮换，旋转凸轮15下方连有锥形凸台杆16，锥形凸台杆16设置于两个锁舌卡块10之间，且锁舌卡块10朝向锥形凸台杆16的一侧设有锥形凹槽23，锥形凸台杆16的顶端设有第二弹簧18，锁舌卡块10下方连接有第一弹簧17。如图5所示，使用前，哑铃主 体和配重铃片5均置于基座上。使用时，如图6、7所示，根据需要的重量按下对应配重铃片5的按钮9，套筒部19处于固定位置，推转凸轮14顶部从通孔部22伸出，此时按钮9下移，推动推转凸轮14、旋转凸轮15、锥形凸台杆16一起下移，锥形凸台杆16的凸出锥形面会推动两边的锁舌卡块10分别向外移动，限位卡槽21限制锥形凸台杆16的旋转，从而卡住配重铃片5上的内侧壁槽11，此时旋转凸轮15上的第二凸出面27被置于套筒部19中的浅位凹槽，阻止整个连杆的回升。当再次按动按钮9时，旋转凸轮15上的第二凸出面27顶部的斜切面会和套筒部19上的第三斜面28配合，推动旋转凸轮15旋转位移，从而使旋转凸轮15上的第二凸出面27被置于套筒部19中的深位凹槽，整个连杆在第二弹簧18的推动下上移，锥形凸台杆16复位，锁舌卡块10在第一弹簧17的作用下也复位，被卡配重铃片5被释放，达到减少配重铃片5的功能。
如图1所示，铃片座2外边部挡板上开设有扇形槽29，形成一侧的手握手柄4，从而使得在两边铃片座2边部上又分别增加了一个手握柄，这样在这一款哑铃上就有六个手柄，大大增加了使用者手握哑铃的方式，使用者在克服哑铃重量的力矩也随之大大增加，手握手柄4在根据人体工程学下，特别设置对称的圆弧和平面相结合外型，手握使用舒适。
如图1、2所示，通过重量调节装置7内部电路及传感器的设置，铃片座2外边部挡板上设有对应显示屏30可显示按钮9按下的数量并显示计算出哑铃的总重量、运动的时间、速度、次数及能量的消耗数值，方便使用者直观感知自己的锻炼情况。
如图3所示，重量调节装置7顶部设有安全卡锁31，安全卡锁31位于按钮9的一侧，防止在使用哑铃时误触按钮9导致配重铃片5的滑落而造成伤害。
实施例3：如图9、图10所示，还可将配重铃片5做成方形等其它形状，并将手柄设置为一只和五只，来增加产品的多样性。
