Description

一种握力器 技术领域
本发明涉及健身器材领域，尤其涉及一种握力器。
 背景技术
握力器是一种用于训练手或前臂的肌肉强度的健身器材，常见的握力器包括一对手柄和在阻碍手柄的接近运动的方向上施加力的弹簧。
为了适应不同人群的需要，可将握力器的弹簧和手柄之间设置为可以拆卸的，弹簧插入手柄的深度越深，杠杆越短，握力变大；弹簧插入手柄的深度越浅，杠杆越长，握力变轻，这样就可以充分利用力学中杠杆原理来调节使用者所需的握力，从而达到调节握力的目地。
 技术问题
然而，传统的可调节握力的握力器无法让使用者准确得知调节后的握力的具体数值，且在调整手柄与弹簧的相对位置后，进行固定时需要利用螺丝等部件来锁紧，操作较为繁琐。
 技术解决方案
基于此，有必要提供一种便于用户准确调节握力的握力器。
一种握力器，包括：一个弹性件，弹性件包括一个弹性主体及由弹性主体两端分别延伸形成的两个弹性脚；两个中空的手柄；以及两中空的壳体，两个壳体分别活设于两个手柄上；两个弹性脚分别依次穿设于两个壳体及两个手柄中，弹性脚表面具有间隔设置的数个凹部；握力器还包括设置于手柄内的手柄限位件，手柄限位件可部分收容于凹部。
作为优选，手柄包括中空的手持部及设于手持部上方的中空的柱体，柱体包括远离手持部的头部、连接手持部的尾部和连接头部和尾部的腰部。
作为优选，柱体的头部设有收容手柄限位件的一个手柄通孔，手柄通孔沿垂直于柱体的中心轴的方向贯穿头部的侧壁，手柄限位件的长度大于头部的侧壁的厚度，手柄限位件可在手柄通孔内沿垂直于柱体的中心轴的方向做往复运动。
作为优选，壳体分为远离手柄的第一部分和靠近手柄的第二部分，第一部分围成第一区间，第二部分围成第二区间，第一区间的直径小于第二区间的直径，第一区间与第二区间之间通过一斜面连接。
作为优选，头部的外径大于腰部的外径，尾部设有螺纹，壳体与柱体通过螺纹连接。
作为优选，握力器还包括固定于中空壳体的壳体限位件，壳体上设有收容壳体限位件的壳体通孔，壳体限位件朝向壳体的中心轴方向凸设，壳体通孔设于壳体的第二部分。
作为优选，壳体在外力作用下可使弹性脚相对手柄做往复调节。
作为优选，柱体的头部凸设一限位部，壳体内壁凸设一抵止部，抵止部与限位部相抵接，腰部绕设有一弹簧。
作为优选，抵止部的上表面与限位部的下表面相抵接，抵止部的下表面与弹簧一端相连，弹簧的另一端与尾部相连。
作为优选，头部的直径大于腰部的直径，壳体内壁靠近手持部的位置凸设有一台阶部，台阶部与弹簧一端相抵接，弹簧另一端与头部相抵接。
作为优选，壳体的外径与手持部的外径相同，壳体的内径大于柱体的外径。
作为优选，手柄通孔分为靠近柱体的中心轴的内通孔和远离柱体中心轴的外通孔，内通孔的直径小于外通孔的直径，手柄限位件包括收容于外通孔的帽部和收容于内通孔的主体部，帽部的直径大于内通孔的直径。
作为优选，手柄通孔为锥形孔，且手柄通孔的靠近中心轴的位置的孔径小于远离中心轴的位置的孔径。
作为优选，弹性脚具有至少一个平面，凹部设置于平面上。
本发明利用弹性脚上的凹部与手柄上的手柄限位件配合的方式，实现调节握力器时的准确定位。当壳体与手柄松脱的时候，手柄限位件可脱离凹部，使得弹性脚在手柄内可自由活动；当壳体与手柄固定的时候，手柄限位件与凹部卡合，起到限位的作用，可牢固地将弹性脚固定于手柄内。

握力器1还包括设置于手柄12内的手柄限位件14，手柄限位件14可部分收容于凹部112。
手柄12包括中空的手持部121及设于手持部121上方的中空的柱体122，柱体122包括远离手持部121的头部123、连接手持部121的尾部124和连接头部123和尾部124的腰部125。在本实施例中，手持部121与柱体122一体成型。
柱体122的头部123上设有收容手柄限位件14的一个手柄通孔126，手柄通孔126沿垂直于柱体122的中心轴的方向贯穿头部123的侧壁。手柄限位件14的长度大于头部123的侧壁的厚度，手柄限位件14可在手柄通孔126内沿垂直于柱体的中心轴的方向做往复运动。
具体地，手柄通孔126分为靠近柱体122的中心轴的内通孔1261和远离柱体中心轴的外通孔1262，内通孔1261的直径小于外通孔1262的直径，手柄限位件14包括收容于内通孔1261的主体部141和收容于外通孔1262的帽部142，帽部142的直径大于内通孔的直径1261，使得手柄限位件14朝向柱体122的中心轴运动的时候，帽部142能够卡在外通孔1262中，而手柄限位件14远离柱体122的中心轴运动的时候，能够顺利脱离手柄通孔126。
壳体13分为远离手柄12的第一部分131和靠近手柄12的第二部分132。第一部分131围成第一区间1310，第二部分132围成第二区间1320，第一区间1310的直径小于第二区间1320的直径，第一区间1310与第二区间1320之间通过一斜面133连接。
头部123的外径大于腰部125的外径，尾部124的外表面设有螺纹，壳体13的内表面设有与尾部124对应的螺纹，壳体13与柱体122通过螺纹连接，并能通过旋转产生相对运动。壳体13与柱体122旋紧时，手柄限位件14位于第一区间1310内，并卡进凹部112中；壳体13与柱体122分离时，手柄限位件14沿着斜面133从第一区间1310进入第二区间1320，由于第二区间1320的直径大于第一区间1310的直径，手柄限位件14可以脱离凹部112。手柄限位件14可以脱离凹部112后，弹性脚111可在手柄12内活动，按照使用者的需求调整弹性脚111插入手柄12的深度，来调整握力。调整完毕，再次旋紧壳体13与柱体122时，手柄限位件14沿着斜面133从第二区间1320进入第一区间1310，受第一部分131的挤压，手柄限位件14落入凹部112并卡合于凹部112，从而使弹性脚111相对手柄12固定。
握力器1还包括固定于壳体13的壳体限位件15，壳体13上设有收容壳体限位件15的壳体通孔130，壳体限位件15朝向壳体13的中心轴方向凸设，壳体通孔130设于壳体13的第二部分132，即壳体限位件15位于第二区间1320。由于第一区间1310的直径小于第二区间1320的直径，壳体限位件15只能在柱体122的腰部125的范围内活动，壳体13与柱体122分离时，壳体限位件15与柱体122的头部123卡合，使得壳体13无法完全脱离手柄12。
在本实施例中，壳体13的外径与手持部121的外径相同，壳体13的内径大于柱体122的外径。手持部121和壳体13的外表面设有防滑纹路，用于增加摩擦力，便于使用者旋紧或松脱壳体13和手柄12。弹性脚111具有一个平面1110，数个凹部112均设置于平面1110上。凹部112的数量为4个，弹性脚111上对应每个凹部的位置标注有相应的握力值。手柄12的中空部分与弹性脚111的形状相适配，弹性脚111的远离弹性主体110的一端设有斜切口113，便于引导弹性脚111插入手柄12的中空部分并在手柄12内活动。在其他实施例中，弹性脚可以是有一个以上平面的棱柱形，一个弹性脚上的凹部的数量在两个以上，可以是3个或5个。
本实施例的握力器1利用弹性脚111上的凹部112与手柄12上的手柄限位件14配合的方式，实现调节握力器时的准确定位。当壳体13与手柄12松脱的时候，手柄限位件14可脱离凹部112，使得弹性脚11在手柄12内可自由活动；当壳体13与手柄12固定的时候，手柄限位件14与凹部112卡合，起到限位的作用，可牢固地将弹性脚111固定于手柄12内。
 本发明的实施方式
本发明还提供了另一种握力器的实施例。
如图4-7所示，一种握力器2，包括一弹性件21、两中空的手柄22和两中空的壳体23，两个壳体23分别可活动地连接于两个手柄22上。弹性件21包括一弹性主体210及由弹性主体210两端分别向下延伸形成的两个弹性脚211，弹性脚211依次穿设于壳体23及手柄22中。
壳体23在外力作用下可使弹性脚211相对手柄22做往复调节。具体地，弹性脚211表面具有间隔设置的数个凹部212，握力器2还包括设置于手柄22内的手柄限位件24，手柄限位件24可部分收容于凹部212。手柄22包括中空的手持部221及设于手持部221上方的中空的柱体222。柱体222包括远离手持部221的头部223、连接手持部221的尾部224和连接头部223和尾部224的腰部225。在本实施例中，手持部221与柱体222分离设置并采用螺纹连接，在生产握力器时便于组装。
柱体222的头部223上设有收容手柄限位件24的一个手柄通孔226，手柄通孔226沿垂直于柱体222的中心轴的方向贯穿头部223的侧壁。手柄限位件24的长度大于头部223的侧壁的厚度，手柄限位件24可在手柄通孔226内沿垂直于柱体的中心轴的方向做往复运动。在本实施例中，手柄通孔226为锥形孔，且手柄通孔226的靠近柱体222的中心轴的位置的孔径小于远离该中心轴的位置的孔径。
柱体222的头部223凸设一限位部2231，壳体23的内壁凸设一抵止部231。限位部2231与抵止部231卡合，可限制壳体23相对于手柄22运动的活动范围，阻止壳体23与手柄22完全脱离。
头部223的直径大于腰部225的直径， 腰部225绕设有一弹簧227，在本实施例中，抵止部231的上表面与限位部2231的下表面相抵接，壳体23的内壁靠近手持部221的位置凸设有一台阶部232，台阶部232与弹簧227一端相抵接，弹簧227另一端与头部223相抵接。这种情况下，使用者手持手柄22和壳体23并将二者拉开时，弹簧227被压缩，手柄限位件24相对抵止部231运动并脱离抵止部231，从而使手柄限位件24脱离凹部212，进而使弹性脚211从手柄22中松脱。使用者松手时，弹簧227的弹力带动手柄22和壳体23相对运动，抵止部231抵压手柄限位件24，使手柄限位件24重新卡进凹部212，进而使弹性脚211固定于手柄22中。
在另一个实施例中，抵止部231的下表面与限位部2231的上表面相抵接，抵止部231的下表面与弹簧227一端相连，弹簧227的另一端与尾部224相连。
由于弹性脚211表面设有凹部212，手柄限位件24卡进凹部212时即可使弹性脚211相对手柄固定。又因为弹簧227分别与手柄22和壳体23相连，使用者手持手柄22和壳体23并将二者拉开时，弹簧227被拉长，手柄限位件24相对抵止部231运动并脱离抵止部231，从而使手柄限位件24脱离凹部212，进而使弹性脚211从手柄22中松脱。使用者松手时，弹簧227的弹力带动手柄22和壳体23相对运动，抵止部231抵压手柄限位件24，使手柄限位件24重新卡进凹部212，进而使弹性脚211固定于手柄22中。
综上所述，本实施例的握力器具有以下有益效果：当壳体23受到外力作用与手柄22分离时，柱体222相对壳体23移动，使得手柄限位件24不受抵止部231挤压而脱离凹部212，从而使弹性脚211从手柄22中松脱。待调整好手柄22与弹性脚211的相对位置后，对壳体23卸力，弹簧227使得壳体23复位，抵止部231重新对手柄限位件24进行挤压固定，进而使弹性脚211固定于手柄22中。上述步骤使得握力器操作起来十分便捷，解决了握力器在固定时需要利用螺丝等部件来锁紧而使得操作繁琐的问题。
本发明利用弹性脚上的凹部与中空手柄上的限位件配合的方式，实现调节握力器时的准确定位。当中空壳体与中空手柄松脱的时候，限位件可向中空柱体外部活动，使得弹性脚在中空手柄内可自由活动；当中空壳体与中空手柄旋紧固定的时候，限位件向中空柱体内凸出，并与弹性脚上的凹部卡合，起到限位的作用，可牢固地将弹性脚固定于中空手柄内。上述方案使得握力器操作起来十分便捷，且定位准确，解决了调节握力器时操作繁琐的问题。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
