[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] like Figure 1 、 Figure 2 、Figure 3 and Figure 4 As shown, the utility model is an adjustable hallux valgus corrector, comprising a U-shaped plate 1, a side plate 2 and an L-shaped plate 3. A mounting hole 11 is provided on one side of the U-shaped plate 1, and a positioning groove 9 connected to the mounting hole 11 is provided on the inner side surface of the U-shaped plate 1. One end of the side plate 2 extends through the positioning groove 9 to the mounting hole 11. A positioning hole 5 is provided on the side plate 2 opposite to the mounting hole 11. A positioning ring 6 is protruded on the outer surface of the side plate 2, and the positioning ring 6 is inserted into the mounting hole 11. The L-shaped plate 3 is installed on the end of the side plate 2 away from the U-shaped plate 1.

[0021] In this embodiment, one end of the L-shaped plate 3 is bent upward to form a fixing portion 7. The fixing portion 7 is arranged in an arc-shaped structure and is arranged to fit the outer side surface of the side plate 2. A first screw hole is provided on the fixing portion 7, and a second screw hole 10 is provided on the side plate 2 opposite to the first screw hole. The first screw hole and the second screw hole 10 are threadedly connected with a hand bolt 8. The L-shaped plate can be quickly installed and disassembled by rotating the hand bolt.

[0022] In this embodiment, both sides of the U-shaped plate 1 are bent inward to form a wrapping portion, thereby increasing the contact area with the foot.

[0023] In this embodiment, the cross-section of the side panels 2 is arranged in an arc-shaped structure, and the degree of curvature of the side panels 2 matches the degree of curvature of the two sides of the U-shaped panel 1. The inner side surfaces of the side panels 2 are arranged flush with the inner side surfaces of the U-shaped panel 1, so that after wearing, the feet can be tightly integrated with the U-shaped panels and the inner side surfaces of the side panels, and the side panels are fixed by the pressing force between the feet.

[0024] In this embodiment, the U-shaped plate 1 is made of elastic plastic material, so that the U-shaped plate can be bent, making it convenient to wear.

[0025] In this embodiment, a positioning rod 4 is installed on one end surface of the U-shaped plate 1 facing the L-shaped plate 3 . The positioning rod 4 is arranged in an “L”-shaped structure and is located in the middle of the U-shaped plate 1 .

[0026] In this embodiment, the open end surface inside the positioning hole 5 is chamfered, which increases comfort when worn and avoids discomfort when the protruding part at the junction of the big toe and the first metatarsal bone on one side of the foot is inserted into the positioning hole.

[0027] When wearing, the wrapping parts on both sides of the U-shaped plate can be directly opened outward. After the wrapping parts are bent, the foot can step into the inner side of the U-shaped plate, and the big toe enters the L-shaped plate. After releasing, the elasticity of the U-shaped plate can clamp the wrapping parts on both sides of the foot. The protruding part of the junction of the big toe and the first metatarsal on one side of the foot can be inserted into the positioning hole, thereby increasing the positioning effect of the U-shaped plate. The side panels can apply an outward pulling force to the L-shaped plate, thereby correcting the big toe outward.

[0028] Among them, when worn, the positioning rod can be inserted between the second toe and the third toe to complete the positioning of the U-shaped plate, avoiding the situation that the U-shaped plate retreats along the foot and increasing stability.

[0029] On the contrary, after spreading the two wrapping parts outwards again, the U-shaped plate can be directly removed, and the big toe can also be disengaged from the L-shaped plate, greatly facilitating disassembly.

[0030] Among them, after disassembly, the positioning ring on the side plate can be removed from the mounting hole, enabling the side plate to be directly disassembled. After rotating the hand-tightening bolt, the fixing part can be disengaged from the side plate to complete the disassembly of the L-shaped plate, greatly increasing the convenience of replacement.

[0031] Among them, this device needs to be customized. It is necessary to measure the width and length of the foot to produce different U-shaped plates and side plates, and multiple L-shaped plates need to be set. Different lengths of L-shaped plates are installed according to subsequent recovery to ensure the correction effect.

[0032] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
