Description

一种健身器便捷无级配重机构 技术领域
本申请涉及健身设备的技术领域，尤其涉及一种健身器便捷无级配重机构。
背景技术
随着人们生活水平的不断提高，人们对身体健康的重视程度也不断增加，锻炼健身已经成为一种时尚，拥有一个良好的体魄，不但能让人精力充沛，更好的投入到学习以及工作中，而且也能让人更加自信，但是现在人们的学习和工作节奏都很快，闲余时间并不是很多，很多人因为没有时间而无法去到健身房等地方进行身体锻炼，导致有心锻炼却没有条件，所以许多人选择购买家用的健身器材进行锻炼。
相关技术中，授权公告号为CN207429577U的一篇中国专利文献中，记载了一种可调节健身器材配重，包括配重块和配重底座，还包括辅助配重块，辅助配重块有多种，每种配重块至少有一块，且每种辅助配重块的重量均不一致，每块辅助配重块上均设置有固定块，叠置在最上方的配重块上对应设置有多个固定槽，辅助配重块通过固定块可固定在任一固定槽中，组合安装的辅助配重块的最大重量小于一块配重块的重量；固定块的侧面包括倾斜面和固定面，固定槽的槽壁对应设置有倾斜槽面和固定槽面，固定面上设置有凸出部，凸出部上设置有固定孔，固定槽面设置有凹槽部，凹槽部上设置有固定机构；所述固定块与所述辅助配重块为一体式结构，所述凸出部为设置在所述固定块侧面的弧形凸起，所述弧形凸起沿所述辅助配重块的顶部延伸至底部；所述固定孔位于所述凸出部靠近所述辅助配重块的顶部的一端，所述凸出部位于所述辅助配重块的底部处设置有抵压部。
现有健身器材的配重机构都是通过插销方式改变配重块的数量，从而达到健身过程力的拉力大小调节，若干的配重块叠放在一个固定不动的滑槽内，配重块需有两根固定的滑动杆来固定配重块的滑动路线，配重块沿固定的滑轨上下滑动；有一根拉力杆由上往下穿过所有的配重块，并在拉力杆上有固定的插销孔与每个配重块中间的插销孔对应，健身过程拉动拉力杆上下运动，健身过程调节拉力大小是通过插销插入配重块中间的孔与拉力杆上对应的孔达到固定拉力杆与配重块，从而实现健身过程拉力大小的调节。
发明人认为，现有健身器材拉力调节需要预置很多个配重块,导致健身器重量非常大,浪费原材料，且调节配重范围受配重块重量影响。
发明内容
为了减少资源浪费，降低健身器材的重量及让调节配重更加自由，本申请提供一种健身器便捷无级配重机构。
技术方案：一种健身器便捷无级配重机构，包括与地面连接固定的固定框，所述固定框上转动连接有张紧椎体和固定椎体,所述张紧椎体和固定椎体之间设置有连接两者的变速摩擦环；所述张紧椎体的中心固定连接有张紧椎体中心轴，所述张紧椎体通过张紧椎体中心轴转动连接在固定框上,所述张紧椎体中心轴的轴向上设置有椎体张紧弹簧；所述固定椎体的中心固定有固定椎体中心轴，所述固定椎体通过固定椎体中心轴转动连接在固定框上,所述固定椎体中心轴的一端设置有拉绳收集器，所述拉绳收集器上缠绕有拉绳。
作为一种优选的技术方案，所述固定框上设置有调节配重大小的调节组件。
作为一种优选的技术方案，所述调节组件包括无级变速调节盘、变速调节滑座和变速调节螺杆，所述无级变速调节盘固定在变速调节螺杆的一端，所述变速调节螺杆转动连接在固定框上，所述变速调节滑座套设在变速调节螺杆上。
作为一种优选的技术方案，所述变速调节滑座上设置有变速摩擦环限位板，所述变速摩擦环套设在变速摩擦环限位板上。
作为一种优选的技术方案，所述调节组件还包括两个变速调节滑轨，两个所述变速调节滑轨相互平行固定在固定框上，所述变速调节滑座滑动配合在变速调节滑轨上。
作为一种优选的技术方案，所述固定框上靠近无级变速调节盘一侧设置有无级变速数字指示盘。
作为一种优选的技术方案，所述固定椎体中心轴的一端设置有止回转单向轴承。
作为一种优选的技术方案，所述固定椎体中心轴的另一端设置有拉绳收集器单向轴承。
作为一种优选的技术方案，所述拉绳收集器的外表面设置有螺旋状螺纹。
作为一种优选的技术方案，所述张紧椎体中心轴的一端设置有用于均衡椎体张紧弹簧的弹性反力的力收集发条。
有益效果：1、根据所需要的配重，张紧椎体和固定椎体连接，并通过变速摩擦环连接两者，根据变速摩擦环所在的位置，来决定张紧椎体和固定椎体之间的传动比，即固定椎体转一圈，张紧椎体转多圈；同时，张紧椎体的转动受椎体张紧弹簧控制，当连接点施加的力越靠近椎体张紧弹簧，所需要的力越大，反之，则越小；相比于现有技术， 配重比的增加是靠增加配重机构的重量，而本申请是靠弹性势能的转化，因此，具有减轻配重机构重量的作用，从而实现减轻健身器材的重量。
2、力收集发条的设计，保证张紧椎体受到椎体张紧弹簧产生的弹性反力保持恒定。
3、止回转单向轴承的设计，使得固定椎体只能单向转动，进而避免张紧椎体反转。
4、无级变速数字指示盘的设计，使得无级变速调节盘转动圈数能具体显示，提高调整配重比的精准度。
5、通过减少配重块的使用，具有减少资源浪费的优点；调节配重拥有更大的范围且不受单个配重块的重量影响最小配重数。
6、调节配重更加自由，不受单个配重块重量的限制。
7、由于配重机构重量的减轻，从而实现用该配重机构的健身器材重量的减轻。
8、该配重机构更加环保，由于健身器材具有一定使用年限，传统健身器材配备配重块，随着健身器材的使用寿命到达，配重块也被弃用；本申请的配重机构不需要利用配重块配重，从而达到环保的目的。
