Reciprocating motion mechanism and fascia gun

Abstract

The invention discloses a reciprocating motion mechanism. The reciprocating motion mechanism comprises a power part, wherein a cam is arranged above the power part, an eccentrically-arranged sliding rod is arranged on the cam, the sliding rod is fixed to the cam, a sliding block is arranged on the sliding rod, a shaft rod doing front-back reciprocating motion is arranged on the sliding block, andthe sliding block is fixed below the shaft rod. According to the reciprocating motion mechanism, an eccentric wheel is adopted to drive the sliding block to do reciprocating motion through the slidingrod, and therefore the shaft rod on the sliding block is driven to do reciprocating motion together; and the sliding rod on the eccentric wheel does left-right reciprocating motion in the sliding block, the acting force of the sliding rod on the sliding block is only forward or backward, the axis of the shaft rod coincides with the axis of a front cover all the time, deviation is not prone to happening after long-time use, and vibration and noise are small.

Description

technical field [0001] The invention relates to the field of fascia guns, in particular to a reciprocating mechanism and a fascia gun. Background technique [0002] Fascia gun is a tool for soft tissue rehabilitation. It relaxes the soft tissue of the body through high-frequency impact. Fascia gun is an effective way to treat soft tissue pain. It stimulates its proprioceptive function, thereby effectively relieving muscle tension and achieving pain relief. the goal of. [0003] Most of the existing fascia guns are driven by a cam to drive the connecting rod to rotate. During the rotation of the connecting rod, the front end moves back and forth, and the driven shaft reciprocates back and forth. The massage head at the front end of the shaft impacts the corresponding part at high speed. One week, the direction of the pulling force of the connecting rod on the shaft changes constantly. After a long time of use, the shaft is prone to vibration and noise. Contents of the inve...
