Description

Technical Field

[0001] The invention belongs to the technical field of fascia guns, and in particular relates to a fascia gun movement and a working method thereof. Background Art

[0002] Fascia Gun, full name of Fascia Gun, is a high-frequency percussion therapy for fascia relaxation. After fitness or exercise, the sympathetic nerves are overexcited, causing the muscles to be too tense when static, resulting in fascia adhesion, which affects recovery and growth. When fascia is adhered or damaged, the body often has many uncomfortable reactions: stiff, hard, tight muscles, low local skin temperature, moisture; loose, inelastic or reduced elasticity, and concave muscle tissue; irregular block or cord-like hard tissue under the skin, deep muscle, and between bone joints. This is a way for the body to protect muscles, and it is also a protective mechanism that hinders muscle recovery, especially some deep muscles are difficult to be touched by foam rollers or vibrating foam rollers. Therefore, it is necessary to release these extra excitement through fascia relaxation to solve and alleviate the above problems. Combine dynamic stretching before training and static stretching after training to make muscles and joints more beautiful and safe.

[0003] Compared with the daily use of foam rollers for relaxation, the fascia gun relaxes muscles and fascia more deeply and accurately. The fascia gun generates 2000-3000 vibrations per minute, and impacts the target parts of the body through the gun head to help relax and recover the muscle and soft tissue, and promote blood circulation. At the same time, it effectively dissipates a large amount of creatine produced by the human body due to fatigue in exercise, work, and life, and has a very good effect in relieving body fatigue; its high-frequency oscillation can penetrate deep skeletal muscles, relax skeletal muscles instantly, and the meridians, nerves and blood vessels are instantly unblocked. At present, the fascia guns on the market (such as Chinese invention patent application CN109758348A and Chinese invention patent application CN109893419A) are only achieved through rotation eccentricity + reciprocating motion of the slider, resulting in large product size, inconvenient storage and carrying, high noise, large jitter, and poor user experience.

DETAILED DESCRIPTION

[0019] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0020] like Figure 1 As shown, this embodiment provides a fascia gun movement, including a motor 47, a crank shaft 22, a rocker arm 16, a shaft block 21, a rocker arm shaft 24, a left connecting rod 20, a right connecting rod 25, a sleeve shaft 29 and a sliding sleeve 27, the horizontal rear end of the crank shaft 22 is fixedly sleeved on the output shaft of the motor 47, the lower end of the rocker arm 16 is rotatably sleeved on the inclined front end of the crank shaft 22, the center hole of the shaft block 21 is rotatably sleeved on the upper end of the rocker arm 16, the rocker arm shaft 24 is transversely penetrated at the rear of the shaft block 21, the rear ends of the left connecting rod 20 and the right connecting rod 25 are correspondingly rotatably sleeved on the left and right ends of the rocker arm shaft 24, the left and right ends of the sleeve shaft 29 are correspondingly transversely penetrated on the front ends of the left connecting rod 20 and the right connecting rod 25, and the rear end of the sliding sleeve 27 is movably sleeved in the middle of the sleeve shaft 29.

[0021] In this embodiment, if Figures 1-2 As shown, the fascia gun movement also includes an elastic sleeve 30, the sliding sleeve head 27 is slidably inserted into the elastic sleeve 30, the inner peripheral side wall of the elastic sleeve 30 is in sliding contact with the outer peripheral side wall of the sliding sleeve head 27, and the inner peripheral side wall of the elastic sleeve 30 is axially provided with at least one circle of multiple equally spaced positioning grooves 49, and the positioning groove 49 is provided with a low friction member 28, and the low friction member 28 is in point / line contact with the outer peripheral side wall of the sliding sleeve head 27. When the sliding sleeve head 27 performs linear reciprocating motion in the elastic sleeve 30, the low friction member 28 in the positioning groove 49 is in point / line contact with the sliding sleeve head 27, and most of the lateral extrusion force generated by the deflection of the sliding sleeve head 27 is converted, and at the same time, a small part of the lateral extrusion force is absorbed by the local deformation of the elastic sleeve 30, thereby solving the problem of abnormal noise and vibration generated by the deflection of the sliding sleeve head 27.

[0022] In this embodiment, the low friction member 28 is preferably but not limited to a wear-resistant ball, and can also be a needle roller, a cylindrical roller, a tapered roller, a roller, etc. The shape of the positioning groove 49 is adapted to half of the low friction member 28, such as a hemispherical groove, a semi-cylindrical groove, or a semi-cylindrical groove. The material of the low friction member 28 is preferably but not limited to POM, wear-resistant rubber, etc. The material of the elastic sleeve 30 is preferably but not limited to rubber, silicone, etc. In order to further improve the effect of the linear reciprocating sliding of the sliding sleeve 27 in the elastic sleeve 30, a layer of grease can be applied inside the positioning groove 49 or outside the low friction member 28, so that the friction between the low friction member 28 and the positioning groove 49 and the sliding sleeve 27 is smaller. In order to make the outer peripheral side of the sliding sleeve 27 more uniformly stressed, and thus make the linear reciprocating sliding effect of the sliding sleeve 27 in the elastic sleeve 30 better, the positioning grooves 49 between two adjacent circles can be staggered.

[0023] In this embodiment, the fascia gun movement also includes a base 8 and a pressure cover 31. The lower part of the elastic sleeve 30 is embedded above the front end of the base 8.
