Ankle joint passive movement device with adjustable fluctuation velocity and angle

The utility model relates to an ankle joint passive movement device with adjustable fluctuation velocity and angle. The ankle joint passive movement device comprises a fixed disk, a lower rotating disk, an upper rotating disk, a pedal disk, a rolling ball, an inner connecting part of the upper rotating disk, a connecting plate, a connecting part of the upper and the lower rotating disks, a ball bearing or a cross universal joint, a slip ring, a spur rack, a straight column, a disk-shaped rack, a first motor, a first gear assembly, a second motor and a second gear assembly, wherein the fixed disk is placed on a stable foundation, the lower rotating disk rotates around the axle center of the fixed disk, and the rolling ball and a groove are additionally arranged between the lower rotating disk and the fixed disk; and power for enabling the lower rotating disk to rotate around the fixed disk is derived from the disk-shaped rack, the second motor and the second gear assembly. The first motor rotates and drives the spur rack to slide up and down along the straight column through the first gear assembly, the spur rack drives the slip ring to slide up and down along the straight column, one end of the connecting plate is hinged with the inner connecting part of the upper rotating disk, and the other end of the connecting plate is hinged with the slip ring. The ankle joint passive movement device can provide passive training in various directions and at different frequencies for an ankle joint, a user can adjust the rotational speed and the angle according to tolerance and demand of the user, and training and rehabilitation needs of people can be satisfied.
