[0050] As Figures 1 to 5 shown, the present invention provides an adjustable plantar massage device, including:

[0051] A rotatable shaft 1 that can rotate forward and backward;

[0052] A massage roller 2, the massage roller 2 includes a roller body 21, a massage intensity adjustment rod 22, a movable massage tooth 23, and an elastic reset member 24. An idle rotation groove 211 that extends in an arc with the axis of the shaft 1 as the center line is provided on the roller body 21. The massage intensity adjustment rod 22 is arranged on the roller body 21 to move radially along the roller body 21. The movable massage tooth 23 is arranged at one end of the massage intensity adjustment rod 22 away from the shaft 1. The elastic reset member 24 is respectively connected to the roller body 21 and the massage intensity adjustment rod 22 to make the massage intensity adjustment rod 22 move radially inward along the roller body 21;

[0053] A cam 3, the cam 3 is fixedly sleeved on the shaft 1, and the outer peripheral wall of the cam 3 is in sliding contact and cooperation with one end of the massage intensity adjustment rod 22 close to the shaft 1;

[0054] A reversing disk 4, the reversing disk 4 includes a turntable 41 fixedly sleeved on the shaft 1 and a transmission block 42 protruding from the end face of the turntable 41. The transmission block 42 is slidably arranged in the idle rotation groove 211 along the extension direction of the idle rotation groove 211.

[0055] In the present invention, the massage intensity adjusting rod 22 is arranged on the roller body 21 to move radially along the roller body 21, and the movable massage teeth 23 are arranged at one end of the massage intensity adjusting rod 22 away from the wheel axle 1. When the massage intensity adjusting rod 22 extends radially outward from the roller body 21, the massage intensity of the movable massage teeth 23 on the sole of the user can be increased; conversely, when the massage intensity adjusting rod 22 retracts radially inward into the roller body 21, the massage intensity of the movable massage teeth 23 on the sole of the user can be decreased. In order to achieve the radial outward movement of the massage intensity adjusting rod 22, the cam 3 is fixedly sleeved on the wheel axle 1, and the outer peripheral wall of the cam 3 is in sliding abutting cooperation with one end of the massage intensity adjusting rod 22 close to the wheel axle 1. When the cam 3 rotates with the wheel axle 1, while the protruding part of the cam 3 is in sliding cooperation with the massage intensity adjusting rod 22, it pushes the massage intensity adjusting rod 22 out of the roller body 21. In order to achieve the radial inward movement of the massage intensity adjusting rod 22, the elastic resetting member 24 is respectively connected to the roller body 21 and the massage intensity adjusting rod 22. When the protruding part of the cam 3 is not in sliding cooperation with the massage intensity adjusting rod 22, the elastic resetting member 24 can make the massage intensity adjusting rod 22 move radially inward along the roller body 21. More importantly: an idle running groove 211 is provided on the roller body 21 with the axis of the wheel axle 1 as the center line and extending in an arc. The reversing disc 4 includes a turntable 41 fixedly sleeved on the wheel axle 1 and a transmission block 42 protruding from the end face of the turntable 41. The transmission block 42 is slidably arranged in the idle running groove 211 along the extending direction of the idle running groove 211. With such a setting, when the direction of rotation of the wheel axle 1 changes, the transmission block 42 starts to slide from one end of the idle running groove 211 and along the extending direction of the idle running groove 211, so that the wheel axle 1 cannot drive the roller body 21 to rotate, that is, the short-term idle running of the wheel axle 1 on the roller body 21 is realized; at the same time, during the period when the wheel axle 1 is idling, the cam 3 still rotates in the reverse direction with the wheel axle 1, and the outer peripheral wall of the cam 3 forms a sliding abutting cooperation with the massage intensity adjusting rod 22, so that the massage intensity adjusting rod 22 extends out or retracts into the roller body 21, that is, the massage intensity of the movable massage teeth 23 on the sole of the user is changed. When the transmission block 42 slides to the other end of the idle running groove 211, the reversing disc 4 drives the roller body 21 again, so that the movable massage teeth 23 massage the sole of the user. For example, as Figure 4 and Figure 5 shown, when the wheel axle 1 rotates in the A direction, the massage intensity adjusting rod 22 is pushed out by the cam 3, and the massage intensity of the movable massage teeth 23 on the sole of the user is greater; when the wheel axle 1 rotates in the direction opposite to the A direction, the massage intensity adjusting rod 22 is pulled back by the elastic resetting member 24, and the massage intensity of the movable massage teeth 23 on the sole of the user is smaller. Therefore, the adjustable sole massage device of the present invention changes the massage intensity of the massage roller 2 on the sole of the user by the forward and reverse rotation of the wheel axle 1.
