Description

Technical Field

[0001] This utility model relates to the field of foot orthosis technology, specifically to a height-adjustable foot orthosis. Background Technology

[0002] Bowlegs are a common foot condition, and foot orthoses are often used to treat them. Patent publication number CN219184366U discloses a height-adjustable foot orthosis, comprising a base, a foot frame, and an arch support. A height matching mechanism is fixedly connected to the upper side of the base, and an orthotic mechanism is fixedly connected to one side of the height matching mechanism. This invention allows the user to check the position of the orthotic mechanism while using the height-adjustable foot orthosis. If the position is unsuitable, a servo motor is activated. The servo motor's rotating shaft drives a connecting tube to rotate within the connecting frame and inner trapezoidal shell. The connecting tube drives a threaded rod to rotate, and the meshing force generated by the rotating threaded rod is transmitted to a slider. The slider and the inner trapezoidal shell engage internally, causing the slider to move upwards, which in turn moves the orthotic mechanism upwards, adjusting its height. By incorporating a height matching mechanism, the height of the orthosis can be adjusted to match the feet of patients of different heights, thus improving the orthotic effect.

[0003] The existing technical solutions mentioned above have the following drawbacks: When wearing the device, the user needs to put their foot through the top ring and the inside of the ring plate. During this process, the user's ankle needs to be straightened in order to put the device through the top ring and the ring plate. When removing the device, the user also needs to straighten their foot. The process of wearing the device is quite cumbersome and reduces the comfort of using the foot orthosis.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a rotating screw, which drives the lifting block and connecting frame to move upwards. The lifting block then drives the sliding rod and clamping plate to move upwards. When the clamping plate is adjusted to a suitable position, it stops moving. The figure shows the clamping plate in an unfolded state, allowing the user to place their foot directly on top of the arch support and insert their lower leg into the foot frame. During the placement of the user's foot and leg, the connecting plate is released, and the tension of the spring causes the connecting plate, sliding rod, and clamping plate to move inwards. When the clamping plate contacts the user's lower leg, it stops moving. This design offers the advantage of convenient wear, as the user does not need to straighten their foot; their foot can be directly inserted into the foot orthosis, improving the comfort of using the foot orthosis.

[0014] 2. By setting a weight-reducing groove, this utility model can reduce the weight of the clamping plate, avoid the clamping plate being difficult to pull during use, and reduce the pulling pressure of the clamping plate. Attached Figure Description

[0021] like Figures 1 to 4 As shown, this utility model provides a height-adjustable foot orthosis, including a frame 1, an arch support 2 fixedly connected to the top of the frame 1, a foot frame 3 fixedly connected to the top of the arch support 2, clamping plates 4 on both sides of the top of the foot frame 3, sliding rods 5 fixedly connected to the front and rear sides of the outer side of the clamping plates 4, lifting blocks 6 sleeved on the surface of the sliding rods 5, tension springs 7 fixedly connected to the outer side of the lifting blocks 6, and a connecting plate 8 fixedly connected to the outer side of the tension springs 7. The surface of the connecting plate 8 is fixedly connected to the surface of the sliding rods 5. A screw 9 is slidably connected to the left side of the foot frame 3. The surface of the screw 9 is threadedly connected to the inside of the lifting block 6. A connecting frame 10 is provided on the rear side of the frame 1. The two sides of the bottom of the connecting frame 10 are fixedly connected to the top of the lifting blocks 6.

[0022] refer to Figure 3 The clamping plate 4 has weight reduction grooves 11 on both the front and rear sides of its top, and the weight reduction grooves 11 are located inside the frame 1.

[0023] As a technical optimization of this utility model, by setting the weight reduction groove 11, the weight of the clamping plate 4 can be reduced, avoiding the clamping plate 4 being difficult to pull during use, and reducing the pulling pressure of the clamping plate 4.

[0024] refer to Figure 2 A knob 12 is fixedly connected to the top of the screw 9, and the knob 12 is located on the top of the frame 1.

[0025] As a technical optimization of this utility model, by setting the knob 12, the user can easily rotate the screw 9, avoiding the screw 9 being difficult to squeeze and thus difficult to rotate, thereby improving the rotation efficiency of the screw 9.

[0026] refer to Figure 2 Limiting blocks 13 are fixedly connected to both the front and rear sides of the lifting block 6, and the surface of the limiting block 13 is slidably connected to the inner wall of the frame 1.

[0027] As a technical optimization of this utility model, by setting the limiting block 13, the lifting block 6 can be stabilized during sliding, avoiding shaking of the lifting block 6 during sliding and movement, which would cause the lifting block 6 to loosen, thus improving the sliding stability of the lifting block 6.

[0028] refer to Figure 2 A vertical rod 14 is fixedly connected to the right side of the frame 1, and a lifting block 6 is slidably connected to the surface of the vertical rod 14.

[0029] As a technical optimization of this utility model, by setting the vertical rod 14, the lifting block 6 can be stabilized by secondary sliding, avoiding shaking of the lifting block 6 during sliding movement, and improving the sliding stability of the lifting block 6.

[0030] refer to Figure 2 A handle 15 is fixedly connected to the surface of the linkage plate 8, and the handle 15 is located on the outer side of the surface of the tension spring 7.

[0031] As a technical optimization of this utility model, by setting the handle 15, it is easier for the user to pull the connecting plate 8 to move, avoiding the difficulty in gripping the connecting plate 8 during the process of moving it, which would make the connecting plate 8 difficult to pull, thus improving the operating efficiency of the connecting plate 8.

[0032] refer to Figure 3 A stabilizing sleeve 16 is fitted onto the surface of the slide bar 5, and the surface of the stabilizing sleeve 16 is fixedly connected to the surface of the lifting block 6.

[0033] As a technical optimization of this utility model, by setting the stabilizing sleeve 16, the sliding rod 5 can be stabilized during sliding, avoiding the sliding rod 5 from shaking during sliding and moving, which would cause the sliding rod 5 to loosen, thus improving the sliding stability of the sliding rod 5.

[0034] The working principle and usage process of this utility model are as follows: When in use, first adjust the height of the clamping plate 4 according to the user's body shape, rotate the screw 9, the screw 9 drives the lifting block 6 and the linkage frame 10 to move upward, the lifting block 6 drives the slide rod 5 and the clamping plate 4 to move upward, when the clamping plate 4 is adjusted to a suitable position, stop moving the clamping plate 4. In the figure, the clamping plate 4 is in the unfolded state, the user can directly place the sole of the foot on the top of the arch pad 2 and put the lower leg into the inside of the foot frame 3. During the process of placing the user's foot and leg, release the linkage plate 8, the tension of the tension spring 7 drives the linkage plate 8, the slide rod 5 and the clamping plate 4 to move inward, when the clamping plate 4 contacts the user's lower leg, the clamping plate 4 stops moving.

[0035] In summary, this height-adjustable foot orthosis, through the coordinated use of the frame 1, arch support 2, foot frame 3, clamping plate 4, sliding rod 5, lifting block 6, tension spring 7, connecting plate 8, screw 9, and connecting frame 10, solves the problem that when users wear the orthosis, they need to put their feet through the top ring and the ring plate, during which time the user's ankle needs to be straightened to pass through the top ring and the ring plate. When removing the orthosis, the user also needs to straighten their feet. This process is cumbersome and reduces the comfort of using the foot orthosis.
