Embodiment 1

[0037] Such as figure 1 As shown, a schematic diagram of the present invention in use is shown.

[0038] figure 2 The form of the orthopedic insole 1 and the connection details of the orthopedic insole 1 and the adjustable stiffness device 2 are shown. The orthopedic insole 1 is provided with an arch support curved surface 100 for supporting the arch of the foot. The arch support curved surface is preferably according to the user's foot. The shape of the bottom is customized; the shape and size of the arch support surface can also be set according to experience, and the user can choose the arch support surface that suits the shape of the arch of the foot by trying it on. There are two holes 101' and 102' on the orthopedic insole 1, and the bolts 101 and 102 connect the stiffness-adjustable device 2 with the orthopedic insole 1 through the holes 101' and 102'.

[0039] Such as image 3 As shown, the force deformation diagram of the present invention is shown. After the ort...

Embodiment 2

[0051] Figure 10 and Figure 11 It is a front view and a top view of another adjustable stiffness device, wherein: one end of the open elastic member 4 is fixedly connected to the central shaft 6 through the connecting rod 5, the central shaft 6 is fixedly connected to the gear 13, and the bolt 102 passes through the central shaft 6 and the gear 13, and connect the adjustable stiffness device 2 with the orthopedic insole 1. The difference between embodiment 2 and embodiment 1 is that embodiment 2 adopts manual control gear rotation, and then drives the opening elastic member 4 to rotate, thereby changing the opening elastic member 4, and then change the output stiffness of the open elastic member 4.

[0052] Correspondingly, a set gear 14 is provided below the gear 13 , and the central shaft 6 is provided with threads corresponding to the position of the set gear 14 . When the stiffness of the adjustable stiffness device 2 needs to be changed, loosen the fixed gear 14, and ...

Abstract

A rigidity continuous adjustable ankle orthopedic shoe pad includes a shoe pad body and a rigidity adjustable device arranged on the bottom of the shoe pad body; the rigidity adjustable device includes a rotation mechanism and an opened elastic member, wherein one end of the opened elastic member is fixedly connected to the rotation mechanism, and the other end of the opened elastic member is movably connected to a propodeum bottom of the shoe pad; the rotation mechanism is arranged on a heel portion of the shoe pad; the rotation mechanism drives the opened elastic member to rotate horizontally so as to achieve rigidity continuous adjustment from the propodeum bottom to the heel portion. The rigidity adjustable device is simple and compact in structure, is easy to operate, is high in accuracy, can adjust the vertical supporting rigidity of an arch support curved surface of the ankle orthopedic shoe pad is adjusted, and can meet the rigidity demands of ankles in different motion conditions or/and different damage conditions.

Description

technical field [0001] The invention relates to a technology in the field of daily necessities, in particular to a device for adjusting the vertical stiffness of the arch support curved surface of an orthopedic insole by changing the stiffness of a continuously adjustable stiffness device. Background technique [0002] Plantar fasciitis is one of the most common foot diseases among middle-aged and elderly people, which seriously affects the health and quality of life of middle-aged and elderly people. Foot and ankle surgeons typically treat plantar fasciitis with arch support / ankle orthotic insoles that provide vertical support to the patient's arch through the arch support surface on the arch support / ankle orthotic insole / The purpose of correcting the affected foot. With the recovery / enhancement of the patient's ankle function, the height of the patient's arch changes or / and the strength of the arch is further strengthened, so different support heights and stiffnesses ar...
