Description

Technical fields:

[0001] This utility model belongs to the field of massage equipment technology, and specifically relates to a grasping and kneading massage head structure, particularly a scheme in which several circumferentially distributed grasping arms move synchronously to grasp and knead muscles for massage. Background technology:

[0002] Massage equipment provides muscle relaxation, relieves tension, and promotes physical and mental well-being, making it widely popular in the market and leading to the emergence of various targeted massage devices. In mechanical massage equipment, most use motors to drive the massage heads to rotate or oscillate, achieving muscle massage. The coordinated movement of a pair of massage heads can also achieve a kneading effect. Massage heads are divided into two types: fixed and rocker. Fixed massage heads are single-unit structures, consisting of a single plastic ball head or multiple ball heads of varying sizes and heights that rotate synchronously. Rocker massage heads are positioned on a turntable via an axis, rotating with the turntable and also undulating to conform to the curves of the human body. However, these systems still lack diversity and limit the massage experience.

[0003] How to provide a novel technical solution is the subject of this invention. Utility Model Content:

[0004] The purpose of this invention is to design a gripping massage head structure with several gripping arms distributed in a circle to simultaneously grip and massage muscles.

[0006] The turntable is located inside the fixed ring, and its edge has a multi-cam structure with cam grooves formed on the cam surface. The fixed ring has through holes equal in number to the gripping arms, and radially extending grooves from the through holes. A support seat is provided on the upper edge of each groove. A slider is placed in each groove, and the near-center end of the slider is machined into a ball head that matches the cam groove. A spring is provided between the far-center end and the outer end of the groove to keep the ball head in contact with the cam groove. The lower end of the gripping arm is hinged to the slider. The rotation of the turntable drives the slider to swing the gripping arm via the cam groove on the cam surface. One of the two hinged positions on the gripping arm is a long groove fit to provide swing margin.

[0007] A spring baffle is provided at the outer end of the slide groove, which is embedded in the reserved slot of the slide groove to form a fixed position; the spring baffle is provided with a spring guide notch, and a spring guide post is provided at the end of the slider.

[0008] The turntable is located below the fixed ring, and a cam groove is formed on its upper surface; the lower end of the gripping arm, which is positioned on the support base, is inserted into the cam groove, and the gripping arm is driven to move by the rotating cam groove.

[0009] The upper half of the gripping arm is an arc segment facing the output shaft, and the end is an integrated finger pressure head or a flexible finger pressure head.

[0010] A multi-ball massage head is also provided in the space enclosed by the grasping arm. The massage head is locked to the end of the output shaft that passes through the turntable. The height of the highest ball of the massage head is within the range of the height change of the finger pressure head when the grasping arm swings.

[0011] This utility model features a unique concept, reasonable design, and multi-point synchronous massage. Through the synchronous movement of several acupressure heads, it can achieve multi-point muscle movements of closing and pinching, opening and abducting, and the force changes when the grasping arm swings. Combined with the massage head at the end of the output shaft, it can create different massage experiences, greatly enriching the massage techniques and improving the massage experience.

[0028] Reference Figures 1 to 5 The kneading massage head structure includes a turntable 2, a retaining ring 3, and a gripping arm 4, all locked to the output shaft. The retaining ring 3 is fixed to the gearbox housing or other fixed parts, such as the housing or top cover of the massage equipment, and is a stationary component. The retaining ring 3 is concentric with the output shaft 1. Here, concentricity means that when the retaining ring is a circular ring, it is coaxial with the output shaft 1. The retaining ring can also be polygonal or any shape that is rotationally symmetrical, with its center concentric with the output shaft. Several support seats 31 are distributed around the circumference of the retaining ring 3. It is preferable that the support seats are evenly distributed, but it is also possible to distribute them in pairs.

[0029] The gripping arm 4 can be oscillating and positioned on the support base 31. Its lower end is driven by the continuous cam groove 21 on the turntable 2. Several gripping arms 4, driven by the turntable 2, perform synchronous closing or opening movements to achieve the function of grasping, pinching and abducting and stretching muscles.

[0030] The drive methods for turntable 2 are as follows:

[0031] 1. External surface drive: The turntable 2 is located inside the fixed ring 3, and its edge has a multi-cam structure, generally three to six cams are preferred, and it has a uniform streamlined structure to facilitate smooth drive; cam grooves 21 are formed on the cam surface of the edge; the fixed ring 3 has through holes 32 distributed in the same number as the gripping arms 4, and the through holes 32 extend outwards to radially arranged sliding grooves 33, with a support seat 31 provided on the upper edge of the sliding grooves 33; a slider 5 is placed in each sliding groove 33, and the near-center end of the slider 5 is machined into a ball head 51 that matches the cam groove 21, and a spring 6 is provided between the far-center end and the outer end of the sliding groove 33 to always keep the ball head 51 in contact with the cam groove 21; it can transmit changes in the cam surface of the turntable 2 in a timely manner, and the slider can at least constrain the vertical sliding by using the ball head 51 to cooperate with the cam groove 21.

[0032] The lower end of the gripping arm 4 is hinged to the slider 5. The rotation of the turntable 2 drives the slider 5 via the cam groove 21 on the cam surface, causing the gripping arm 4 to swing. One of the two hinged positions on the gripping arm 4 has a long groove to provide swing allowance. Figure 4 and Figure 5 The junction hole between the gripping arm 4 and the support base 31 is a long slot hole 43; alternatively, the hinge position with the slider 5 can be a long slot.

[0033] A spring baffle 34 is provided at the outer end of the slide groove 33. The spring baffle 34 is embedded in the reserved slot of the slide groove 33 to form a fixed position. The spring baffle 34 is provided with a spring guide recess 341 and the end of the slider 5 is provided with a spring guide post 52.

[0034] II. End face driving, refer to Figure 6 and Figure 7 The turntable 2 is located below the fixed ring 3, and the upper surface is formed with a cam groove 21, which is actually a continuous multi-cam shape. The lower end of the gripping arm 4, which is positioned on the support base 31, is inserted into the cam groove 21, and the gripping arm 4 is driven to move by the rotating cam groove 21.

[0035] Furthermore, the upper half of the gripping arm 4 is an arc segment 41 facing the output shaft, and the end is an integrated acupressure head 42 or a flexible acupressure head, mimicking the action of five fingers grasping.

[0036] A multi-spot massage head 7 is also installed within the space enclosed by the grasping arm 4. The massage head 7 is locked to the end of the output shaft 1 that passes through the turntable 2. The height of the highest point of the massage head 7 is within the range of height variation of the acupressure head 42 when the grasping arm swings. The superposition of the massage heads 7 can change the monotonous massage technique of the acupressure head 42 alone. By utilizing the ball points 71 on the rotating massage head and the acupressure head 42 to form a kneading combination, the massage experience is enriched.
