Description

Technical Field

[0001] The present invention relates to the technical field of fascia guns, in particular to a novel fascia gun. Background Art

[0002] With the improvement of people's quality of life, massage devices have gradually become a common tool for people's health care and relaxation. For example, the fascia gun, also known as the deep myofascial impactor, is a soft tissue rehabilitation tool that relaxes the body's soft tissues through high-frequency impact. The fascia guns currently on the market are connected by a connecting rod and sleeve with a bearing. Since the connection is located at the front end of the first connecting rod, it will cause a large angle of swing when driven to move, resulting in noise. The bearings need to be coated with silencer oil. Under high-speed vibration of the bearings, the silencer oil will overflow, and the concentration of the silencer oil is not easy to configure. The manufacturing process of the bearings has high requirements. The collision of the small ball in the bearing with the bearing wall will also cause noise. At present, most fascia guns use I-shaped shock-absorbing rubber pads and insert screws at the four corners to fix the motor bracket. The I-shaped shock-absorbing rubber pads are used to fix the motor bracket. The fixing method of the pad requires at least three to be installed flat, which leads to a large number of workpieces and high difficulty in assembly. Since it is inconvenient to fix with screws axially, it requires a lot of housing space and is not conducive to saving space. The sleeve currently on the market is in a rolled form with a crack in the middle. In the actual assembly process, a metal sleeve needs to be put on the outer layer to clamp it. This requires a high clamping force of the metal sleeve. If the clamping force of the metal sleeve is too small, the sleeve will be deformed, which will cause noise during internal movement. If the clamping force of the metal sleeve is not enough, more silencing oil needs to be added to reduce the noise. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of fascia gun to solve the problems of high noise, high assembly difficulty and high processing requirements. The present invention provides a new type of fascia gun, including a casing, a driving motor, a transmission assembly and a massage assembly, the transmission assembly including an eccentric wheel, a connecting rod and a sliding bearing, the motor shaft of the driving motor is connected to the eccentric wheel to drive the eccentric wheel to rotate, the eccentric shaft on the eccentric wheel is connected to the connecting rod, the connecting rod is arranged inside the sliding bearing, the connecting rod is provided with a pin groove near the front end, the sliding bearing is provided with two upper and lower pin holes, the pin groove and the pin hole are fixedly connected by a pin, the pin hole and the pin groove are both provided with a first silicone sleeve, the pin hole is provided with a first silicone sleeve at the outer position to wrap it, and the first silicone sleeve is fitted and connected with the inner wall of the sliding bearing.
