DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-8 As shown, a rocker-type double-guide rod fascia gun movement includes a double-guide sleeve transmission rod 7 and a double-guide rod base 2.

[0029] A swing rod 22 is provided on the rear axis of the double guide sleeve transmission rod 7, and the swing rod 22 is fixedly connected to the double guide sleeve transmission rod 7 separately or integrally. A connecting piece 21 that can be deformed and swung left and right is provided at the connection point, and the front of the connecting piece 21 is connected to the double guide sleeve transmission rod 7, and the rear is connected to the swing rod 22. The swing rod 22 is in the shape of a water droplet with a small front and a large rear. The swing rod 22 has swing spaces 23 that penetrate up and down on both sides and the rear, which can ensure the movement space of the swing rod 22, the bearing mounting seat 15 and the output shaft 16 when they make eccentric and rotational movements, reduce the collision of the swing rod 22, the bearing mounting seat 15 and the output shaft 16 with the surroundings of the double guide rod base 2, and reduce noise. A circular bearing fixing hole 17 is provided at the rear of the swing rod 22, and a bearing 14 is provided in the circular bearing fixing hole 17. The outer ring of the bearing 14 is fixedly arranged in the circular bearing fixing hole 17, and the inner ring of the bearing 14 is fixedly arranged on an eccentric shaft. Or the rear end of the swing rod 22 is provided with a bearing fixing pin, on which a bearing 14 is fixed, and the outer ring of the bearing 14 is fixedly arranged on an eccentric wheel, and the double guide sleeve transmission rod 7 is formed by injection molding of engineering plastics or die-casting of aluminum alloy. The bearing 14 rotates eccentrically to achieve synchronous left-right equidistant swing of the swing rod 22, and the swing rod 22 drives the double guide sleeve transmission rod 7 to axially equidistantly reciprocate linear motion.

[0030] Two guide sleeves 3 are fixed or integrated on the left and right sides of the double guide sleeve transmission rod 7. The two guide sleeves 3 are made of fine processing or inlaid with metal or engineering plastic wear-resistant sleeves. The axes of the two guide sleeves 3 are parallel to the axis of the double guide sleeve transmission rod 7. Two guide rods 1 and four fixing blocks 11 for fixing the guide rods are coaxially arranged on both sides of the double guide rod base 2 with the two guide sleeves. The two guide rods 1 are respectively slidably matched with the two guide sleeves 3. The four fixing blocks 11 are respectively arranged on the front and rear sides of the two guide sleeves 3. The two ends of each guide rod 1 are fixed on the front and rear two fixing blocks 11. Each fixing block 11 is provided with a guide rod fixing hole 20 with an axial direction in the front and rear direction. Each guide rod 1 is provided with a retaining ring groove 18 at both ends. The guide rod 1 passes through the guide rod fixing hole 20 and is fixed to the fixing block 11 by a retaining ring 8. The guide rod 1 is made of engineering plastic or carbon steel. The movement of the double guide sleeve transmission rod 7 is more stable through the guidance of the double guide rods and the double guide sleeves.

[0031] Through the transmission cooperation between the bearing 14 serving as the eccentric wheel and the circular bearing fixing hole 17 on the double guide sleeve transmission rod 7, the eccentric rotation of the eccentric wheel is converted into synchronous axial equidistant reciprocating linear motion of the double guide sleeve transmission rod 7. By arranging the guide rod 1 and the guide sleeve 3, the stability of the double guide sleeve transmission rod 7 is enhanced, the reciprocating linear motion of the massage head is made smoother, and the accuracy of the massage head in massaging acupoints and meridians is ensured.

[0032] The movement also includes a lubrication system, which includes an oil storage cup 5, an oil passage 13 and an oil cup cover 9. The oil storage cup 5 is integrally arranged or separately fixedly arranged above the guide sleeve 3. The bottom of the oil storage cup 5 is provided with a plurality of oil passages 13 leading to the guide sleeve 3 and communicating with the guide rod 1. Grease or semi-solid lubricant is placed in the oil storage cup 5. When the oil storage cup 5 and the guide sleeve 3 synchronously reciprocate linearly on the guide rod 1, the grease or semi-solid lubricant penetrates between the guide rod 1 and the guide sleeve 3 through the oil passage 13 under the action of vibration, gravity and thermal conduction, so as to achieve long-lasting and uniform lubrication of the guide rod 1 and the guide sleeve 3. The oil cup cover 9 is fixed to the upper opening of the oil storage cup 5 by screws 10.

[0033] The traditional fascia gun movement has large movement resistance and noise during use due to the exhaustion of lubricating oil in the later stage. However, the present rocker-type double-guide rod fascia gun movement has an oil storage cup 5 above the guide sleeve 3. When the oil storage cup 5 and the guide sleeve 3 move back and forth synchronously on the guide rod 1, the grease or semi-solid lubricating oil penetrates into the guide rod 1 and the guide sleeve 3 through the oil channel under the action of vibration, gravity and thermal conduction, thereby achieving long-lasting and uniform lubrication of the guide rod 1 and the guide sleeve 3, thereby reducing the movement resistance and noise of the double guide sleeve transmission rod 7.

[0034] The double guide rod base 2 is a rectangular semi-open shell with an opening facing upward. The double guide rod base 2 is integrally formed by injection molding of engineering plastics or die-casting of aluminum alloy. A plurality of double guide rod base fixing holes 6 for fixed connection with a fascia gun are arranged on or on both sides of the central axis of the double guide rod base 2, and the double guide rod base fixing holes 6 are 2, 3, 4 or more. In this embodiment, a total of 4 double guide rod base fixing holes 6 for fixed connection with a fascia gun are arranged on the left and right sides or the front and back sides of the double guide rod base 2.

[0035] The swing-rod type double-guide rod fascia gun movement also includes a motor 4 and a bearing mounting seat 15, the bearing mounting seat 15 is fixedly connected to the output shaft 16 of the motor 4, and the bearing 14 is fixedly mounted on the bearing mounting seat 15. The axis of the bearing 14 is parallel to and deviates from the axis of the output shaft 16 of the motor 4, and the deviation distance of the bearing 14 is half of the reciprocating linear stroke of the double guide sleeve transmission rod 7, that is, twice the deviation distance of the bearing 14 is equal to the distance of the reciprocating linear stroke of the double guide sleeve transmission rod 7, and the bottom plate 12 of the double guide rod base 2 is provided with a through hole 19, and the bearing 14 and the bearing mounting seat 15 are sequentially inserted into the through hole 19 to fix the motor 4 below the bottom plate 12, and the axis of the output shaft 16 of the motor 4 is perpendicular to the axis of the double guide sleeve transmission rod 7.

[0036] like Fig. 9 As shown, the present invention also provides a fascia gun, including the above-mentioned rocker-type double-guide rod fascia gun movement.

[0037] In addition to the above preferred embodiments, the present invention has other implementation modes.
