TECHNICAL FIELD

[0001] The utility model belongs to the technical field of massage, and particularly relates to a clamping and kneading massage machine core, which can be designed into a massage equipment for clamping and kneading muscle groups such as shoulders and necks. BACKGROUND

[0002] Most of the existing kneading massage equipment has a pair of eccentric or inclined rotating massage heads, which are in contact with the surface of the human body to make a circular motion, and produce reciprocating motion of stretching and tightening on the muscles. Alternatively, the side part of a relatively long massage head produces a conical swing track to realize massage of clamping and loosening on parts that can be clamped, such as the neck, and the force changes too much to simulate the effect of hand kneading. For this reason, various attempts have been made, such as:

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , the massage mechanism comprises a motor 1, a transmission mechanism 2, an eccentric wheel 3 and a massage arm 4; the transmission mechanism 2 generally refers to a gearbox and a simple gear transmission, and in this example, it is a gearbox; it is in transmission connection with the motor and is installed on a base plate 5 to form a whole; the eccentric wheel 3 is locked on the output shaft 21 of the transmission mechanism, and the massage arm 4 is driven by the eccentric wheel 3 to make a swing motion.

[0034] The massage arm 4 comprises a driving massage arm 41 and a driven massage arm 42, and both pass through the base plate 5; the driving massage arm 41 has a driving sleeve 6 fixed at one end, and the driving sleeve 6 is sleeved on the eccentric wheel 3; a limiting mechanism 51 is arranged between the driving sleeve 6 or the driving massage arm 41 and the base plate 5; the driven massage arm 42 is positioned on a guide shaft 7, and is linked with the eccentric wheel 3 on one side of the output shaft 21 through a traction rod 8; the guide shaft 7 is installed on the base plate 5 in parallel with the output shaft 21.

[0035] More specifically, two or more eccentric wheels 3 are fixed on the output shaft 21 of the transmission mechanism, each eccentric wheel 3 is provided with a driving sleeve 6 and drives a driving massage arm 41; one end of the driven massage arm 42 is fixed with a driven sleeve 61, which is sleeved on the guide shaft 7, one end of the traction rod 8 is connected with the driven massage arm 42 or the driven sleeve 61, and the other end is connected with the driving sleeve 6, that is, the driving sleeve 6 moves eccentrically with the eccentric wheel 3, and the driven massage arm 42 swings through the traction rod 8, and the driving massage arm 41 and the driven massage arm 42 produce reciprocating operation of opposite clamping and opposite relaxation.

[0036] Further, the limiting mechanism 51 includes a limiting slot vertically arranged on one side of the bottom plate and a shaft protrusion 62 on the driving sleeve 6 or the driving massage arm 41; the shaft protrusion 62 is inserted into the limiting slot and can slide up and down and rotate swing, keeping the driving massage arm 41 swing within the designed range. Preferably, the shaft protrusion 62 in this example is arranged on the driving sleeve 6.

[0037] This example uses eccentric wheel 3 to drive the driving massage arm 41, which can produce clamping and rubbing action in the vertical plane of the output shaft 21, and two or more driving massage arms 41 and driven massage arms 42 on the output shaft form two rows of synchronous clamping and rubbing action, which can increase the clamping and rubbing range and efficiency.

[0038] Referring to Figure 4 , Figure 5 and Figure 6 , the inclined eccentric wheel 31 is selected to drive the driving massage arm 41 to swing in this example, in addition to the clamping and rubbing in the vertical plane of the output shaft 21, the limiting mechanism 51 can also realize the axial eccentric swing operation, and the feeling of rubbing is brought during clamping. It should be noted that the inclined eccentric wheel refers to the shaft center line of the wheel and the output shaft having an included angle, and a certain eccentricity can be superimposed to increase the amplitude.

[0039] Similarly, two or more inclined eccentric wheels 31 and one eccentric wheel 3 are fixed on the output shaft 21 of the transmission mechanism, each inclined eccentric wheel 31 is provided with a driving sleeve 6 and drives a driving massage arm 41; two or more driven massage arms 42 are fixed on the guide shaft 7, and the guide shaft 7 is movably positioned on the shaft seat 52 of the bottom plate; one end of the traction rod 8 is sleeved on the eccentric wheel 3 through the driving sleeve 6, and the other end is hinged at the eccentric position of the driven massage arm 42 or the guide shaft 7, and in this example, the other end is hinged at the eccentric position of the guide shaft 7, that is, a short arm 71 is welded on the guide shaft, one end of the traction rod 8 is hinged with the end of the short arm 71, and the guide shaft 7 swings to adjust the torque and swing angle. The traction structure of the driven massage arm 42 can also be as shown in Figures 1 to 3 , which only increases the cost of a set of traction mechanism.

[0040] The corresponding limiting mechanism 51 is a long slot on the bottom plate, which allows the active massage arm 41 to pass through and restricts its rotation. Further, the long slot of the limiting mechanism 51 is an inclined structure, which has an angle with the normal projection of the output shaft 21.

[0041] In addition, the active massage arm 41 and the driven massage arm 42 at least have a steel wire core or a nylon rod, which passes through the bottom plate 5 to contact the human body, is wrapped with latex, simulates the structure of fingers, can resist the human body in a larger range, and can also avoid stiffness; or the steel wire core or the nylon rod is fixed with a capsule 43 at the end, or a spherical capsule is directly processed at the end of the nylon rod, which contacts the human body to produce the effect of finger pressure by means of the capsule 43. The steel wire core or the nylon rod has rigidity and elasticity, and can produce a moderate deformation amount when clamped without stiffness. The figure shows that the transmission mechanism 2 has two active massage arms 41 and two driven massage arms 42 on both sides of the output shaft, which forms two rows of clamping or loosening actions and has a certain clamping and kneading width, and can also integrate the local part of the transmission mechanism 2 between the two active massage arms 41 to reduce the occupied height space.

[0042] On this basis, the two active massage arms 41 and the two driven massage arms 42 can be connected into one body by a rubber plate according to needs, which changes the product into a clamp type product to enrich the later development. In order to reduce the resistance generated by rotary friction, bearings 9 are arranged between the active sleeve 6, the driven sleeve 61, the eccentric wheel 3, the inclined cam 31, and the guide shaft 7, which is common sense.
