Description

Technical Field

[0001] This invention relates to the field of massager technology, and in particular to a foot stretching machine mechanism that stretches the legs inward and outward. Background Technology

[0002] In the prior art, foot massage devices include a receiving cavity for the foot to enter and a massage component disposed on the receiving cavity. When in use, the foot is placed in the receiving cavity and then massaged by the massage component. However, this device cannot massage the ankle joint or stretch the calf muscles, which limits its use. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides an inward and outward figure-eight stretching foot machine mechanism. While the massage components are working, the massage seat can be rotated to stretch the calf muscles and provide ankle massage.

[0004] This invention discloses a foot stretching machine mechanism for inward and outward toeing, which includes a massage seat and a massage component disposed on the massage seat. The massage component includes a rotating shaft, a massage wheel that is linked and cooperates with the rotating shaft, and a first driving member for driving the rotating shaft to rotate. The massage seat includes a mounting frame, a first swing frame, and a second swing frame. The rotating shaft is disposed on the mounting frame and passes through the first swing frame and the second swing frame. The rotating shaft is provided with a first eccentric member for driving the first swing frame to swing and a second eccentric member for driving the second swing frame to swing. It also includes a guide structure for limiting and guiding the first swing frame and the second swing frame when swinging.

[0005] Using the above technical solution, when in use, the first driving component can drive the rotating shaft to rotate, and when the rotating shaft rotates, it can drive the massage roller to rotate, thereby realizing foot massage. At the same time, when the rotating shaft rotates, it can drive the first eccentric component and the second eccentric component to work. The guide structure restricts the rotation of the first torsion frame and the second torsion frame, thereby driving them to torsion relative to each other. When torsioning, it will stretch the calf muscles and massage the ankle joint, making it more practical.

[0006] A further feature of the present invention is that the first eccentric component and the second eccentric component are both rotating wheels, and the interior of the rotating wheel is provided with a shaft hole eccentric to the center line of the rotating wheel. The rotating shaft passes through the shaft hole, and a bushing is fixedly provided on both the first torsion frame and the second torsion frame. The rotating wheel is rotatably mounted on the bushing.

[0007] Using the above technical solution, when the rotating wheels rotate relative to each other, the shaft hole is eccentric to the center line of the rotating wheels, causing the rotating wheels to make eccentric movements. These movements are transmitted to the corresponding torsion pendulum frame through the bushing and guided by the guide structure, thereby preventing the first and second torsion pendulum frames from rotating and thus completing the torsion pendulum action. Furthermore, there is no need to set up additional drive components to drive the first and second torsion pendulum frames to swing. Its structural layout is relatively reasonable and can also save manufacturing costs.

[0008] A further feature of the present invention is that a first ball socket is provided on both the first and second torsion pendulum frames, and a second ball socket is provided on the mounting frame corresponding to the position of the first ball socket. A double ball head connecting rod is provided at the corresponding first and second ball sockets, and the double ball head connecting rod cooperates with the corresponding first and second ball sockets to form a guide structure.

[0009] By adopting the above technical solution, the double ball joint is used in conjunction with the first and second ball sockets to enable adaptive adjustment. This not only prevents the first and second torsion pendulum frames from rotating around the rotation axis, but also allows for flexible adaptation, resulting in a relatively reasonable structural layout.

[0010] A further feature of the present invention is that both the first and second torsion frames are provided with toe massage components and mounting plates for mounting the toe massage components, and the mounting plates are guided and slidably moved on the corresponding torsion frames.

[0011] Using the above technical solution, toes can be massaged, and the experience can be enhanced by the relative sliding of the mounting plate.

[0012] A further feature of the present invention is that the mounting plate includes a guide sliding plate and a rotating plate. The first and second torsion swing frames are provided with grooves corresponding to the positions of the guide sliding plates. The guide sliding plate partially slides within the grooves. The rotating plate is rotatably hinged to the guide sliding plate. A second driving member is provided on the first and second torsion swing frames below the rotating plate to drive its rotation. Preferably, the second driving member is an inflatable and deflated airbag.

[0013] By adopting the above technical solution, the toe massager can move and rotate relative to each other through the cooperation of the guide slide plate and the rotating plate, so as to achieve adaptive lifting and massage of the toes. Furthermore, the use of airbags for propulsion provides a cushioning effect, preventing the massage from being too abrupt. Attached Figure Description

[0024] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] This invention discloses a foot stretching machine mechanism for inward and outward toeing, which includes a massage seat 1 and a massage component 2 disposed on the massage seat 1. The massage component 2 includes a rotating shaft 21, a massage wheel 22 that is linked and cooperates with the rotating shaft 21, and a first driving member 23 that drives the rotating shaft 21 to rotate. The massage wheel 22 can be directly sleeved on the rotating shaft 21, or it can be provided with a pulley and drive a secondary rotating shaft to rotate through a synchronous belt. The secondary rotating shaft can also be provided with a massage wheel. In an embodiment of this invention, the massage seat 1 includes a mounting frame 11, a first swing frame 12, and a second swing frame 13. The rotating shaft 21 is disposed on the mounting frame 11 and passes through the first swing frame 12 and the second swing frame 13. The rotating shaft 21 is provided with a first eccentric member 3 for driving the first swing frame 12 to swing and a second eccentric member 4 for driving the second swing frame 13 to swing. It also includes a guide structure 5 for limiting and guiding the swing of the first swing frame 12 and the second swing frame 13.

[0027] Using the above technical solution, when in use, the first driving member 23 can drive the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, it can drive the massage roller 22 to rotate, thereby realizing foot massage. At the same time, when the rotating shaft 21 rotates, it can drive the first eccentric member 3 and the second eccentric member 4 to work. The guide structure 5 restricts the rotation of the first torsion frame 12 and the second torsion frame 13 (this rotation is currently the first torsion frame 12 and the second torsion frame 13 rotating along the rotating shaft 21), thereby driving them to torsion relative to each other. When torsioning, it will stretch the calf muscles and massage the ankle joint, making it more practical.

[0028] Both the first eccentric component 3 and the second eccentric component 4 are rotating wheels. The interior of the rotating wheel is provided with a shaft hole 6 eccentric to the center line of the rotating wheel. The rotating shaft 21 passes through the shaft hole 6. The first torsion pendulum frame 12 and the second torsion pendulum frame 13 are both fixedly provided with bushings 7. The rotating wheel is rotatably mounted on the bushing 7. When the rotating wheels rotate relative to each other, because the shaft hole 6 is eccentric to the center line of the rotating wheel, the rotating wheel makes an eccentric motion, which is transmitted to the corresponding torsion pendulum frame through the bushing 7 and guided by the guide structure 5, thereby preventing the first torsion pendulum frame 12 and the second torsion pendulum frame 13 from rotating, so that they can complete the torsion pendulum action. There is no need to set an additional driving component to drive the first torsion pendulum frame 12 and the second torsion pendulum frame 13 to swing. Its structural layout is relatively reasonable and can save manufacturing costs. Of course, it is also possible to use an inclined eccentric wheel to squeeze the first torsion pendulum frame 12 and the second torsion pendulum frame 13 to achieve torsion pendulum.

[0029] Both the first torsion pendulum frame 12 and the second torsion pendulum frame 13 are provided with a first ball socket 51. The mounting frame 11 is provided with a second ball socket 52 corresponding to the first ball socket 51. A double ball head connecting rod 53 is provided at the corresponding first ball socket 51 and second ball socket 52. The double ball head connecting rod 53 cooperates with the corresponding first ball socket 51 and second ball socket 52 to form a guide structure 5. Through the cooperation of the double ball head connecting rod 53 with the first ball socket 51 and the second ball socket 52, it can make an adaptive adjustment, which can prevent the first torsion pendulum frame 12 and the second torsion pendulum frame 13 from rotating around the rotation axis, and can also flexibly adapt to changes. The structural layout is relatively reasonable.

[0030] Both the first swing frame 12 and the second swing frame 13 are equipped with toe massagers 8 and mounting plates 9 for mounting the toe massagers 8 (the toe massagers can be massage bumps or protrusions, etc.). The mounting plates 9 slide on the corresponding swing frames to massage the toes. The relative sliding of the mounting plates 9 can enhance the experience.

[0031] The mounting plate 9 includes a guide sliding plate 91 and a rotating plate 92. The first torsion frame 12 and the second torsion frame 13 are provided with a groove 10 corresponding to the position of the guide sliding plate 91. The guide sliding plate 91 is partially guided and slid in the groove 10. The rotating plate 92 is rotatably hinged to the guide sliding plate 91. The first torsion frame 12 and the second torsion frame 13 are provided with a second driving member 20 below the rotating plate 92 to drive it to rotate. Preferably, the second driving member 20 is an inflatable and deflated airbag. Through the cooperation of the guide sliding plate 91 and the rotating plate 92, the toe massager 8 can move and rotate relative to each other to achieve adaptive lifting massage of the toes. The airbag is used for pushing, which has a buffering effect and is not too harsh. Of course, the second driving member can also be an electric cylinder, a pneumatic cylinder or a motor.
