Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1 - Figure 4 A high-risk infant early intervention training assistance device provided by the present invention includes a foot support assembly 1. The foot support assembly 1 includes a bottom support 101. A sector-shaped groove 102 is opened on the lower surface of the bottom support 101. A connecting plate 103 is rotatably connected inside the sector-shaped groove 102. One end of the connecting plate 103 is fixedly connected with a soft bottom plate 104. A foot sleeve 105 is adhered to the top surface of the soft bottom plate 104. An ear block 106 is fixedly connected to the upper surface of the bottom support 101. A clamping plate 107 is connected to the outer surface of the ear block 106 through a rivet. An arc-shaped leg sleeve 108 is connected to the inner side of the clamping plate 107 through a rivet;

[0030] Regarding the specific structure of the adjustment assembly 2, please refer to Figure 1 and Figure 5 - Figure 7 . The adjustment assembly 2 includes an outer cylinder 201. A first gear ring 202 is fixedly connected to the inner wall of the outer cylinder 201. The first gear ring 202 is meshed with a second gear ring 203. The bottom surface of the second gear ring 203 is fixedly connected with a reel 204. A reel rod 205 is fixedly connected to the inside of the reel 204. An adjustment thin rope 206 is sleeved inside the reel rod 205. A sleeve rod 207 is fixedly connected to the bottom surface of the reel 204. One end of the sleeve rod 207 is rotatably connected with a sleeve 208. And a compression spring 209 is sleeved on the outer surface of the sleeve rod 207. A pin rod 210 is fixedly connected to the center of the other bottom surface of the reel 204. One end of the pin rod 210 is inserted with a knob 211. One end of the adjustment thin rope 206 is fixedly connected with a rope end 212.

[0031] Furthermore, an ear block 106 is fixedly connected to each position on the upper surface of the base 101 near both sides. Rectangular holes are formed at both ends of the arc-shaped leg sleeve 108. A binding strap 3 is connected in one of the rectangular holes. The outer surface of the binding strap 3 is sewn with Velcro. The lower surface of the base 101 is flush with the lower surface of the soft bottom plate 104. There is a gap between the front end of the base 101 and the rear end of the soft bottom plate 104. A jack 109 is formed inside the fan-shaped groove 102. One end of the connecting plate 103 away from the soft bottom plate 104 is fixedly connected with a buckle 110. The buckle 110 is rotatably connected inside the jack 109.

[0032] By setting the foot support assembly 1, its various components work together to provide support and fixation for the foot correction training of high-risk infants. Among them, the base 101 serves as the support foundation. The ear blocks 106 thereon are connected to the splints 107. The fan-shaped groove 102 on the lower surface cooperates with the buckle 110 of the connecting plate 103. When the foot sleeve 105 can be pulled to shift left or right through the adjusting assembly 2, during the process, the connecting plate 103 drives the soft bottom plate 104 and the foot sleeve 105 to rotate flexibly. The soft bottom plate 104 provides auxiliary support for the foot sleeve 105. When wearing, the arc-shaped leg sleeve 108 is sleeved on the calf. By inserting the binding strap 3 into the other rectangular hole of the arc-shaped leg sleeve 108, and then tightening the binding strap 3 to make the arc-shaped leg sleeve 108 fit on the calf, and using Velcro to fix the binding strap 3, in this way, the foot support assembly 1 can be fixedly worn on the foot of the child.

[0033] Furthermore, an airbag cushion 111 is adhered to the inner wall of the foot sleeve 105, and a buckle one 112 is fixedly connected to the upper surface of the foot sleeve 105. A buckle two 113 is fixedly connected to the outer surface of the arc-shaped leg sleeve 108. An elastic band 114 is sewn and connected inside the buckle one 112.

[0034] By setting the foot sleeve 105 to directly wrap the foot, the airbag cushion 111 provided at the top of its inner wall can fit on the instep, so as to increase the comfort and prevent abrasion of the instep. By inserting one end of the elastic band 114 into the buckle two 113, and Velcro is also sewn on the outer surface of the elastic band 114. In this way, the distance between the foot sleeve 105 and the arc-shaped leg sleeve 108 can be adjusted, so as to correct the situation of the child's foot turning downward.

[0035] Further, there are two sets of adjusting components 2. One side of the rope end 212 is fixedly connected to the outer wall of the foot sleeve 105. The bottom of the outer cylinder 201 is connected to the outer surface of the splint 107 by screws. The sleeve 208 is fixedly connected to the outer surface of the splint 107. A through groove is formed on the outer peripheral surface of the winding rod 205, and an adjusting thin rope 206 is inserted into the through groove. One end of the compression spring 209 abuts against the bottom surface of the winding disc 204, and the other end of the compression spring 209 abuts against the outer surface of the splint 107. A keyway is fixedly connected to the outer surface of the pin rod 210, a key groove is formed inside the knob 211, and the key groove and the keyway are mutually fitted. A collar 213 is fixedly connected to the outer surface of the pin rod 210.

[0036] By providing an adjusting component 2 on each of the two splints 107 of the footrest component 1, turning the knob 211 can drive the pin rod 210 to rotate. The pin rod 210 drives the second gear ring 203 to rotate, and the second gear ring 203 drives the winding disc 204 to rotate. The winding disc 204 drives the winding rod 205 connected to its inside to rotate. In this way, the winding rod 205 drives the adjusting thin rope 206 to wind. Thus, the adjusting thin rope 206 pulls the rope end 212, and the rope end 212 pulls the foot sleeve 105. In this way, the angular position of the foot sleeve 105 can be adjusted, so as to correct the situation of the child's talipes varus or valgus.

[0037] Further, an auxiliary wheel component 4 is rotatably connected to the outer surface of the splint 107. For the specific structure of the auxiliary wheel component 4, please refer to Figure 1 and Figure 8 , the auxiliary wheel component 4 includes a pin shaft 401, a wire wheel 402 is rotatably connected to the outer surface of the pin shaft 401. The auxiliary wheel component 4 further includes a limiting plate 403, the limiting plate 403 is clamped on the outer surface of the pin shaft 401, and a turning knob 404 is threadedly connected to the outer surface of the pin shaft 401.

[0038] When the adjusting component 2 works and the adjusting thin rope 206 is tightened to pull the rope end 212, the adjusting thin rope 206 will contact the wire wheel 402 of the auxiliary wheel component 4. The wire wheel 402 can rotate flexibly on the pin shaft 401. This makes the rolling friction between the adjusting thin rope 206 and the wire wheel 402 during the movement process. Compared with direct friction, the friction force is greatly reduced, making the winding and release of the adjusting thin rope 206 smoother. Furthermore, it ensures that the foot sleeve 105 can be pulled more smoothly and the angular position can be adjusted more accurately, effectively correcting the child's talipes varus or valgus. At the same time, the limiting plate 403 can prevent the adjusting thin rope 206 from detaching from the wire wheel 402 and ensure its stability during work.

[0039] In use, first put the foot sleeve 105 on the child's foot so that the heel contacts the base 101. Then put the arc-shaped leg sleeve 108 on the child's calf. Insert the strap 3 into the rectangular hole at one end of the arc-shaped leg sleeve 108, tighten the strap 3, and fix it with Velcro to make the arc-shaped leg sleeve 108 fit the calf, thereby fixing the foot support assembly 1 on the child's foot. The airbag cushion 111 on the inner wall of the foot sleeve 105 fits the instep, increasing comfort and preventing abrasion. Then insert one end of the elastic band 114 into the buckle two 113, and adjust the distance between the foot sleeve 105 and the arc-shaped leg sleeve 108 by using the Velcro on the outer surface of the elastic band 114 to correct the child's foot drop. Subsequently, rotate the knob 211 to drive the pin rod 210 to rotate, and then make the second gear ring 203, the reel 204, and the winding rod 205 rotate. The winding rod 205 winds and adjusts the thin rope 206, pulls the rope head 212 and the foot sleeve 105, and adjusts the angular position of the foot sleeve 105 to correct the child's clubfoot or valgus. During this process, the adjusting thin rope 206 contacts the wire wheel 402 of the auxiliary wheel assembly 4, and the rotation of the wire wheel 402 reduces the friction. The limit plate 403 prevents the adjusting thin rope 206 from detaching from the wire wheel 402.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
