Description

Technical Field

[0001] This utility model relates to the field of flat foot correction technology, and in particular to a flat foot correction insole. Background Technology

[0002] Newborn babies have physiologically flat feet. As children grow and develop, they undergo physiological changes, and with walking, running, jumping, and other activities, the arch of the foot gradually appears. However, during this formation process, various unpredictable factors can lead to abnormal arch development, such as high arches or flat feet. This can easily result in falls and injuries, even damaging other parts of the body.

[0003] Currently, to address flat feet, a rigid arch support structure is typically added to the arch area of ​​the insole to improve arch support and correct the arch. However, this structure only supports and improves the longitudinal arch and offers little improvement to the transverse arch, therefore it is not effective in correcting flat feet.

[0004] Therefore, there is an urgent need to provide an insole that has a simple structure and can effectively provide a corrective effect. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a flat foot corrective insole with a simple structure that can effectively improve the correction effect of flat feet.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a flat foot corrective insole, including an insole body, characterized in that: an upward first protrusion is provided at the front of the insole body, the first protrusion is arranged along the width direction of the insole body and is located at the corresponding position of the metatarsal body and close to the corresponding position of the metatarsal head.

[0007] Furthermore, the first protrusion is located between the middle and the outer side of the insole along the width direction, and is arc-shaped, with the height of the first protrusion gradually decreasing from the middle to both ends.

[0008] Furthermore, the middle part of the first protrusion is directly opposite the corresponding position of the fourth metatarsal head, and its length is 2-3 cm.

[0009] Furthermore, the first protrusion includes a support piece and a protruding portion, the protruding portion and the support piece being located on the upper and lower sides of the insole body respectively; wherein, the protruding portion is connected to the support piece through an adjusting rod passing through the insole body, wherein the adjusting rod is vertically arranged.

[0010] Furthermore, a vertically threaded sleeve is embedded in the protrusion, corresponding to the position of the adjusting rod. The lower end of the threaded sleeve passes through the protrusion, and the upper end extends to the middle of the protrusion. The lower end of the adjusting rod is fixedly connected to the support plate, and the upper end has threads and is connected to the threaded sleeve through the threads.

[0011] Furthermore, the protrusion is made of plastic.

[0012] Furthermore, the arch portion of the insole body is also provided with a second upward protrusion.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The structure is simple. By setting the first protrusion in the ball of the foot, it can provide lateral support to the foot bones, especially the fourth metatarsal head, and compress the other metatarsal heads upward, thus effectively improving the fit of the insole for flat feet and providing better results.

[0015] 2. The first protrusion adopts an adjustable structure, which can be adjusted according to different flat foot conditions and different correction stages, thereby making the insole more adaptable and the correction effect better. Attached Figure Description

[0021] Example: See Figure 1 A flat foot corrective insole includes an insole body 1. A first upward protrusion 2 is provided at the front of the insole body 1. The first protrusion 2 is positioned along the width of the insole body 1 and is located at the corresponding position of the metatarsal body and close to the corresponding position of the metatarsal head. The first protrusion 2 is located between the middle and outer sides of the insole along its width and is arc-shaped, with its height gradually decreasing from the middle to both ends. As an optimization, in implementation, the middle of the first protrusion 2 is directly opposite the corresponding position of the fourth metatarsal head, and its length is 2-3 cm. This solution provides lateral support to the foot through the first protrusion 2, especially supporting the fourth metatarsal head, to compress the other metatarsal heads (first, second, and third metatarsal heads) upward, thereby forcing them to move upward and effectively improving the insole's fit to the flat foot, resulting in better performance.

[0022] In specific implementation, the first protrusion 2 includes a support plate and a protruding part, which are located on the upper and lower sides of the insole body 1, respectively. The support plate is made of a rigid material, such as a metal sheet or a plastic sheet. The protruding part is made of plastic to give it a certain rigidity and prevent it from becoming flush with the upper side of the insole due to pressure. The protruding part is connected to the support plate through an adjusting rod that passes through the insole body 1, and the adjusting rod is vertically oriented. In actual processing, a vertically oriented threaded sleeve is embedded in the protruding part, corresponding to the position of the adjusting rod. The lower end of the threaded sleeve passes through the protruding part, and the upper end extends to the middle of the protruding part. The lower end of the adjusting rod is fixedly connected to the support plate, and the upper end has threads and is connected to the threaded sleeve through the threads. For easy adjustment, a slotted or Phillips head groove is provided on the lower side of the support plate, so that it can be adjusted with a flathead screwdriver or a Phillips head screwdriver. This solution can be adjusted according to different flat foot conditions and different correction stages, making the insole more adaptable and the correction effect better.

[0023] As an optimization, the arch portion of the insole body 1 is also provided with a second protrusion 3 that protrudes upwards; thereby cooperating with the first protrusion 2 to achieve bidirectional support for the foot bones in both longitudinal and lateral directions, further improving the effect of flat feet improvement.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
