Problems solved by technology

[0004] This kind of fascia gun has a simple structure, but in actual use, the needs of users are often different. Some require a large vibration of the massage head to achieve deep massage; while others require a small vibration of the massage head to achieve soothing massage. The fascia gun obviously cannot meet the requirements for use

Embodiment Construction

[0028] The present invention will be further described with reference to the accompanying drawings.

[0029] Such as Figure 1 to Figure 5 As shown, a linkage mechanism with variable eccentricity for a massage gun includes a driven eccentric shaft track block 2 and a rotating shaft 1 fixed on the output shaft of the motor.

[0030] A mounting hole 21 is provided on the driven eccentric shaft track block 2 , and the axis of the mounting hole 21 coincides with the axis of the driven eccentric shaft track block 2 . The rotating shaft 1 is rotatably connected in the mounting hole 21 and connected with the driven eccentric shaft track block 2 through the positioning mechanism 3 .

[0031] The positioning mechanism 3 includes a locking hole 31 and a tightening screw 32 . The locking hole 31 is opened on the track block 2 of the driven eccentric shaft and communicates with the mounting hole 21 , and the jacking screw 32 is threaded in the locking hole 31 and is used to interfere wi...

Abstract

The invention relates to the field of massage guns, and discloses a linkage mechanism with a variable eccentric distance for a massage gun. The linkage mechanism comprises a driven eccentric shaft rail block and a rotating shaft fixed on a motor output shaft; a mounting hole is formed in the driven eccentric shaft rail block; the rotating shaft is rotationally connected into the mounting hole andconnected with the driven eccentric shaft rail block through a positioning mechanism, a sliding groove is formed in the driven eccentric shaft rail block, and an eccentric shaft sliding block is connected into the sliding groove in a sliding manner; and the rotating shaft rotates and drives the eccentric shaft sliding block to move and be positioned through a conduction mechanism so as to drive the driven eccentric shaft rail block to rotate synchronously, and the eccentric shaft sliding block is connected with a massage head through a linkage assembly. The linkage mechanism has the followingadvantages and effects that the scheme utilizes a new mechanical structure to achieve the purpose of meeting different use requirements.

Description

technical field [0001] The invention relates to a linkage mechanism with variable eccentricity for a massage gun. Background technique [0002] Health massage is a behavior based on the theory of traditional Chinese medicine. It can relax muscles, relieve fatigue, dredge meridians, balance yin and yang, and regulate human body functions. Massage with massage equipment is convenient and labor-saving, so it is more and more popular among people. [0003] At present, the Chinese patent with the notification number CN210844172U discloses a fascia gun, which includes a housing, a motor transmission device, a control operation device, a charging device, and a massage head. The motor transmission device includes a motor, an eccentric wheel, a connecting rod and a drive rod; The control operation device includes a single-chip microcomputer, a display screen and operation buttons; the charging device includes a battery, a boost circuit module and a charging jack. The massage head is...
