Abstract

The present invention provides a transmission mechanism, a fascia gun and a working method with an integrated transverse elastic bracket. The transmission mechanism is driven as the bearing of an eccentric wheel mechanism to perform eccentric movement. A circular bearing fixing hole is provided on the transmission rod. The bearing is fixedly arranged in the circular bearing fixing hole and rotates with the transmission rod.

The transmission mechanism adopts an integrated transverse elastic bracket structure design without a guide rod and a guide sleeve, so that there is no friction and lubrication between the moving parts of the fascia gun, which not only greatly saves production costs, avoids operating resistance and oil and dust pollution, but also reduces power loss, increases the endurance time of the fascia gun, reduces the operating noise of the fascia gun, and prolongs the service life of the fascia gun. The structure is simple, compact and portable, and easy to use.

Description

Technical Field

[0001] The present invention belongs to the technical field of massage equipment, and in particular relates to a transmission mechanism with an integrated transverse elastic bracket, a fascia gun and a working method. Background Art

[0002] With the advancement of science and technology, people's living standards are constantly improving. More and more people are beginning to pursue the use of technological products to improve their health and relieve work pressure and physical fatigue. In addition to using masseurs and large and medium-sized massage equipment for massage, small and portable fascia guns have become the favorite of more and more people. The fascia gun, also known as the deep myofascial impactor, is a human soft tissue massage tool that relaxes the body's soft tissue through high-frequency impact. The fascia gun uses its internal special high-speed motor to drive the massage head, generating a high-frequency impact that reaches the deep muscle layer, achieving the effects of reducing local tissue tension, relieving pain, and promoting blood circulation. The traditional fascia gun transmission device is mostly an eccentric wheel driven by a motor, and the eccentric wheel drives the transmission rod to perform reciprocating linear motion. In order to limit the direction of the reciprocating linear motion of the transmission rod, a guide rod and a guide sleeve need to be set between the transmission rod and the fascia gun. In order to reduce movement resistance and noise, lubricating oil needs to be added between the guide rod and the guide sleeve. In actual practical applications, the amount of lubricating oil added is far from enough to meet long-term massage use. The fascia gun will increase power consumption and operating noise due to the lack of lubricating oil. Summary of the invention
