Detailed Description

As shown in fig. 1 to 6, a noise reduction transmission structure of a fascial gun comprises a motor 10, a connecting shaft rod 20, a shaft sleeve 30 and a shell 40, wherein one end of the connecting shaft rod 20 is connected to an output shaft of the motor 10, the connecting shaft rod 20 is arranged in the shaft sleeve 30, the shaft sleeve 30 is fixedly arranged in the shell 40, and a massage head 50 is inserted into the front end of the connecting shaft rod 20 when in use.

The motor 10 drives the connecting shaft rod 20 to reciprocate back and forth in the shaft sleeve 30, and further drives the massage head 50 to reciprocate back and forth, so as to hit the human body through the massage head 50, thereby achieving the effects of massaging and relaxing the human body.

The ball unit 100 is disposed between the connecting rod 20 and the shaft sleeve 30, and the ball unit 100 can firstly reduce the contact area between the connecting rod 20 and the shaft sleeve 30, so as to greatly reduce the friction force therebetween, thereby reducing the working noise.

In practical applications, the ball unit 100 includes a plurality of ball units 110, and a plurality of ball subunits 110 are arranged between the connecting shaft 20 and the sleeve 30, and in practice, the ball unit 100 includes two sets of ball subunits 110.

Each set of the ball subunits 110 includes a plurality of balls 120, and in practice, each set of the ball subunits 110 includes at least three balls 120.

In practical implementation, each of the balls 120 is embedded in the sleeve 30, corresponding to the ball 120, a plurality of ball holes 31 are recessed in the inner surface of the sleeve 30, and a plurality of balls 120 are correspondingly disposed in the ball holes 31, in practice, the balls 120 can rotate in the ball holes 31, and meanwhile, the balls 120 can be fixedly disposed in the ball holes 31.

In a specific implementation, the shaft sleeve 30 is made of an elastic damping material, for example, silicone, and since the shaft sleeve 30 is made of an elastic damping material, the shaft sleeve 30 is disposed between the connecting shaft rod 20 and the housing 40 to achieve the damping and noise reduction effects.
