The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in FIG. 1 to FIG. 4 , the size-adjustable foot pedal for a rehabilitation device of the present invention includes: a foot board main body 1 , an elongated main body 2 , a linkage structure 4 and a foot cover 4 .

As shown in FIG. 1 , the interior of the pedal main body 1 is a hollow structure. As shown in FIG. 4 , a foot cover 4 is installed on the front end of the pedal main body 1 for ease of use and wearing, and an elongated main body 2 is provided on the outer wall of the rear end of the pedal main body 1 . The length between the foot cover 4 and the elongated main body 2 is the length for the pedal to accommodate the user's foot.

As shown in FIG. 3 , several corrugated projections 16 are fixedly mounted on the top outer wall of the pedal main body 1 , where the top outer wall refers to the side of the pedal main body 1 in contact with the user's sole. The corrugated bumps 16 are linearly and equally divided from top to bottom, and a circular rubber pad 15 is arranged below the corrugated bumps 16. The circular rubber pad 15 is fixedly connected with the top outer wall of the pedal body 1, and the corrugated bumps 16 plays an anti-slip effect, and the circular rubber pad 15 can increase the comfort of the user's heel,

As shown in Figure 1, the elongated main body 2 is arranged on the rear end of the pedal main body 1,

Several sliders 22 are arranged on the inner wall of the elongated main body 2,

The chute 21 is arranged on the outer edge of the pedal main body 1 and matches the position of the slider 22,

The push plate 23 is fixedly arranged on the inner side of the elongated main body 2,

The cylinder 11 is arranged on the side of the pedal main body 1 , and the cylinder 11 plays the role of supporting the transverse shaft 12 .

The transverse shaft 12 passes through the cylinder 11 and is rotatably connected with the cylinder 11 . The front end of the transverse shaft 12 has a first bevel gear 14 . The other end of the horizontal shaft 12 is exposed outside the pedal main body 1, and an anti-slip adjustment knob 13 is fixedly installed, and the rotation of the anti-slip adjustment knob 13 can drive the horizontal shaft 12 to rotate.

One end of the linkage structure 3 is rotationally connected with the horizontal shaft 12 , and converts the rotation of the horizontal shaft 12 into a longitudinal thrust, thereby pushing the connecting rod 24 .

One end of the connecting rod 24 is fixedly connected to the push plate 23 , and the top of the other end is fixedly connected to the bottom outer wall of the connecting sleeve frame 31 . The connecting rod 24 is pushed longitudinally by the linkage structure 3 . Thereby push pedal 23 is further promoted to move, reaches the effect of regulating the length of pedal.

As shown in Figure 2, the linkage structure 3 includes:

Cover frame 31, the inner wall of cover frame 31 is provided with internal thread 36, and cover frame 31 is movably connected threaded rod 35 by internal thread 36, and the position of threaded rod 35 and horizontal axis 12 is perpendicular to each other, and the top of threaded rod 35 is fixedly installed with the first Two bevel gears 37, the second bevel gear 37 and the first bevel gear 14 mesh with each other, so that the threaded rod 35 can be driven to rotate when the horizontal shaft 12 is turned.

Several pulley frames 32 are fixedly installed on the outer wall of the sleeve frame 31 . In this embodiment, the number of pulley frames 32 is set to two, which are symmetrically installed on both sides of the sleeve frame 31 . In other embodiments, more sets of pulley brackets 32 may be provided to improve stability or accommodate a longer adjustment range.

Pulley 33 is installed on the front end of each pulley frame 32.

A pair of sliding rails 34 oppositely arranged are fixedly installed on the inner wall of the pedal body 1 , each pulley 33 is inserted into the inner chamber of the sliding rail 34 , and the pulley 33 can slide in the sliding rail 34 .

Working process: If the present invention wants to adjust the length of the pedal main body 1, it only needs to turn the horizontal shaft 12 inwardly through the anti-skid adjustment knob 13. At this time, the horizontal shaft 12 drives the first bevel gear 14 to rotate, and through the Two bevel gears 37 mesh with the first bevel gear 14, the rotation of the second bevel gear 37 drives the threaded rod 35 to rotate, and the threaded rod 35 drives the downward movement of the sleeve frame 31 through the internal thread 36, and each pulley 33 is inserted In the inner cavity of the slide rail 34, the pulley 33 slides under the cooperation of the slide rail 34, which can better stabilize the movement of the sleeve frame 31. The downward movement of the sleeve frame 31 drives the connecting rod 24 to move downward, and then the connecting rod 24 drives the push plate 23 in the extension main body 2 to move downward, and then the outer wall slider 22 of the extension main body 2 slides in the chute 21.

Turning the anti-slip adjustment knob 13 in the opposite direction can shorten the distance between the pedal body 1 and the extension body 2, thereby achieving the effect of shortening the pedals. Therefore, in this embodiment, the pedal main body 1 and the elongated main body 2 can cooperate with each other to extend or shrink, so as to meet the needs of different people's feet.

Although the specific embodiments of the present invention have been shown and described above, those skilled in the art can make various changes, modifications, Alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
