The utility model discloses a one-way self-locking device for a massager, which comprises a transmission shaft, a shaft sleeve, a torsion spring and a large belt pulley; the transmission shaft can be rotated and installed in the shell of the massager; the large belt pulley can be rotated and sleeved on the transmission shaft; the large belt pulley is driven by a power mechanism to rotate the connecting transmission shaft circumferentially; and the transmission shaft is driven by a deflection member. The shaft sleeve is fixed on the transmission shaft, and the torsion spring is connected to the shaft sleeve. The torsion spring is composed of the main body part and the first and second connecting parts arranged on both sides of the main body part. The first connecting part of the torsion spring is overlapped on the shaft sleeve and fitted with the interference of the shaft sleeve, and the main part of the torsion spring is sleeved on the shaft sleeve and fitted with the clearance of the shaft sleeve. The second connecting part of the torsion spring is fixedly connected with the large belt pulley. The utility model realizes one-way self-locking by reducing and enlarging the inner diameter of the torsion spring, and has the advantages of simple structure, safety and reliability, and low cost.

一种按摩器的单向自锁装置
本技术涉及按摩器
,尤其是指一种按摩器的单向自锁装置。
技术介绍
现有技术中,按摩器结构各式各样,而且按摩器功能多样。申请号为201620154219.1公开一种多功能按摩器,包括机芯主体及设于机芯主体上的摇摆臂,电机设于机芯主体中,电机带动传动组件,传动组件传动摇摆臂,使摇摆臂左右偏摆实现拍打式按摩。传动组件由小皮带轮、皮带、大皮带轮、传动轴、偏转座、轴承以及轴承座组成,小皮带轮设置在电机的电机轴上,通过皮带把动力传给大皮带轮,大皮带轮与传动轴连接,偏转座采用两个相间隔安装在传动轴上,偏转座与轴承和轴承座连接,摇摆臂的两端连接在轴承座上,大皮带轮带动传动轴,传动轴传动偏转座,使偏转座带动摇摆臂上下偏摆。为实现传动轴的单向自锁功能,如图1所示,在传动轴10上安装单向轴承20,大皮带轮30固定安装在传动轴10上,电机通过皮带驱使大皮带轮30连动传动轴10转动,由单向轴承20实现传动轴10的单向自锁功能。然而,所述单向自锁结构的缺陷在于:单向轴承20在运动过程中噪音较大,且单向轴承20的使用成本较高。
