[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 to Figure 4 As shown, a foot massage mechanism of a massage chair, the massage mechanism is arranged at the front end of the massage chair, including a frame 10, two footrest structures 20 arranged on the frame 10 for placing feet, and a tension control component 30 located between the two footrest structures 20 and used to control the rotation of the footrest structure 20 relative to the frame 10, the footrest structure 20 has a placement groove 201 for placing the foot; the tension control component 30 includes an assembly plate 31, a linkage plate 32, and a swing fork plate 33 arranged corresponding to the footrest structure 20, and the tension control component also includes an electric push rod 34 rotatably mounted on the rear end column 14 of the frame 10; the frame 10 is fixed with a rotating shaft 12 that rotates with the footrest structure 20 on two opposite side plates 11, the top of the assembly plate 31 is fixedly connected to the inner side of the footrest structure 20, and the bottom end is fixedly connected to the rotating shaft 12. The shaft 12 is rotatably matched, the top of the swing fork plate 33 has a hinged portion 331, and the bottom end has an actuating portion 332 and a rotating portion 333 arranged at intervals, and the rotating portion 333 of the swing fork plate 33 is rotatably set on the frame 10; the middle position of the linkage plate 32 is rotatably matched with the top of the assembly plate 31, and the rear end is rotatably matched with the hinged portion 331 of the swing fork plate 33; the actuating portions 332 of the two swing fork plates 33 are rotatably matched with a control rod 35 fixedly connected to the push rod end of the electric push rod 34. When the push rod end of the electric push rod 34 is extended, the control rod 35 causes the swing fork rod to swing upward clockwise with the actuating portion 332 as the center, and in turn drives the linkage plate 32 to move backward, and the assembly plate 31 drives the pedal structure 20 to swing upward clockwise to stretch the foot located in the pedal structure 20.

[0025] The structures of the various components of the utility model are described below.

[0026] like Figure 1 to Figure 3 As shown, a tension spring 36 is installed at the top of the linkage plate 32, one force-bearing end of the tension spring 36 is connected to the front end of the linkage plate 32, and the other force-bearing end is connected to the hinge 331 of the swing fork plate 33. A sliding column 3311 is vertically fixed to the hinge 331 of the swing fork plate 33. A waist-shaped hole 321 for sliding connection of the sliding column 3311 is provided at the rear end of the linkage plate 32. The sliding column 3311 can rotate in the waist-shaped hole 321. A limiting plate 3312 is welded at the end of the sliding column 3311 for limiting the separation of the sliding column 3311 from the waist-shaped hole 321. Such a design can make the pedal structure 20 swing and stretch the foot more smoothly, so as to gradually stretch the human foot, exercise the joints and ligaments, and be more conducive to the relaxation of the human foot muscles.

[0027] When the push rod end of the electric push rod 34 extends, the hinge part 331 of the swing fork plate 33 swings upward clockwise, causing the sliding column 3311 to slide from the hole wall at one end of the waist-shaped hole 321 to the hole wall at the other end. During this process, the tension spring 36 extends and the pedal structure 20 does not swing; when the push rod end continues to extend, the swing fork plate 33 continues to swing upward clockwise, the sliding column 3311 continues to press the hole wall of the waist-shaped hole 321, so as to drive the linkage plate 32 to move backward, and the assembly plate 31 drives the pedal structure 20 to swing upward clockwise, and stretch the foot located in the pedal structure 20.

[0028] When the force exerted downward by the foot in the pedal structure 20 is greater than the tension of the tension spring 36, the linkage plate 32 of the pedal structure 20 moves forward relative to the swing fork plate 33 to separate the sliding column 3311 from the hole wall of the waist-shaped hole 321, so that the pedal structure 20 can no longer continue to swing upward clockwise, that is, the pedal structure 20 stops the stretching movement on the foot.

[0029] like Figure 2 and Figure 4 As shown, the pedal structure 20 includes a cover shell 21 arranged around the side of the foot and a palm support soft board 22 arranged on the bottom surface of the cover shell 21, and the cover shell 21 and the palm support soft board 22 enclose a placement groove 201; a massage roller shaft 13 corresponding to the palm support soft board 22 is rotatably arranged between the two side plates 11 of the frame 10; with such a design, when the pedal structure 20 rotates to the point where the palm support soft board 22 and the massage roller shaft 13 are in contact with each other, the massage roller shaft 13 can massage the acupuncture points on the sole of the foot in contact with the palm support soft board 22, thereby improving the practicality of the foot massage mechanism.

[0030] like Figure 4 As shown, the pedal structure 20 also includes two foot side airbags 23 arranged on the inner side of the cover shell 21. The two foot side airbags 23 are used to massage the inner and outer sides of the foot respectively. A Sanyinjiao airbag 24 is arranged on the rear side of the cover shell 21 facing the Sanyinjiao acupoint of the foot. Such a design can massage various acupoints of the human foot in a targeted manner.

[0031] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
