具体实施方式
以下结合附图及具体实施例对本发明做详细描述。
请参阅图2至图8所述，本发明揭示的一种按摩器的单向自锁装置，包括传动轴1、轴套2、扭簧3和大皮带轮4。
传动轴1可转动安装在按摩器的壳体5中，如图7及图8所示，通常，在传动轴1两端通过轴承可转动安装在壳体5中。
大皮带轮4可转动套接在传动轴1上，大皮带轮4由动力机构6驱使连动传动轴1圆周转动，传动轴1通过偏转件7驱使按摩件8动作，具体为：传动轴1上固定安装偏转件7，偏转件7随传动轴1运动，偏转件7驱使按摩件8动作。如图7及图8所示，动力机构6为电机，电机通过皮带61驱使大皮带轮4连动传动轴1圆周转动。按摩件8可以为摇臂，传动轴1通过偏转件7驱使摇臂动作。电机还同时驱动揉捏按摩头。
轴套2固定安装在传动轴1上，通常借助销孔和销轴配合固定安装在传动轴1上。扭簧3套接在轴套2上，扭簧3的材质优选为琴钢丝。
扭簧3由主体部31及设置在主体部31两侧的第一连接部32和第二连接部33组成，扭簧3的第一连接部32搭接在轴套2上与轴套2过盈配合，扭簧3的主体部31套接在轴套2上与轴套2间隙配合，扭簧3的第二连接部33与大皮带轮4固定连接。
扭簧3的第一连接部32设置为U型。扭簧3的第二连接部33设置为钩部，该钩部卡在大皮带轮4的凸块41上，如图3所示，螺丝9锁在大皮带轮4上并限位固定扭簧3的第二连接部33。
如图2所示，轴套2上设置挡垣21，扭簧3的第一连接部32轴向限位于挡垣21的一侧。
电机驱使大皮带轮4逆时针运动时，大皮带轮4带动扭簧3旋紧，扭簧3的主体部31内径缩小，使得扭簧3内周面与轴套2外周面之间呈过盈配合，扭簧3与轴套2之间的产生摩擦力加大，从而形成二者之间的自锁；电机驱使大皮带轮4顺时针运动时，大皮带轮4带动扭簧3旋松，扭簧3内径变大，扭簧3内周面与轴套2外周面之间的配合由过盈配合转为间隙配合，从而解除二者之间的自锁。
本发明通过扭簧3内径的缩小与放大实现单向自锁，结构简单，精度要求降低，安全可靠，成本较低。同时，自然状态下，扭簧3的第一连接部32搭接在轴套2上与轴套2过盈配合，扭簧3的主体部31套接在轴套2上与轴套2间隙配合，从而把运动过程中的噪音降到最低。
以上所述仅为本发明的优选实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
