DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] See also Figures 1 to 6 , the present invention provides a technical solution: a bone orthopedic external splint device, comprising: a foot pad 001; Also includes: Leg cover 002, which is arranged above the foot pad 001, and the child's calf is fixed by the leg cover 002, so that the foot pad 001 is firmly worn on the child's foot; Dynamic trigger component 003, which is disposed on the rear side of the foot pad 001, and can detect whether the child is in a walking state; Dynamic telescopic component 004, the dynamic telescopic component 004 is arranged on both sides of the foot pad 001, and the dynamic telescopic component 004 is used to automatically adjust the length according to the walking state of the child, limit abnormal walking posture, and enable the child to maintain a correct gait during walking. The dynamic telescopic component 004 includes a first telescopic frame 401, the outer side of the first telescopic frame 401 is slidably connected to the second telescopic frame 402, the bottom of the first telescopic frame 401 is rotatably connected to the first transmission gear 403 on both sides, the two first transmission gears 403 are meshed and connected with the second transmission gear 404, the top of the second transmission gear 404 is fixedly connected to the adjusting screw 405, and the adjusting screw 405 is threadedly connected to the second telescopic frame 402; The rotating shaft 005 is arranged on both sides of the leg cover 002 .

[0023] Among them, when the child is in a walking or standing state, the dynamic trigger component 003 on the rear side of the foot pad 001 will first contact the ground, and press the pad 302 under pressure to contact the pressure sensor 304. After the pressure sensor 304 receives the pressure from the ground, it immediately energizes the balance tube 110. If the child's walking posture is incorrect, the mercury 130 inside the balance tube 110 will lose balance, and detect whether the child has eversion or inversion of the foot when walking. At the same time, the motor 430 on one side is started, and the first transmission gear 403 and the second transmission gear 404 cooperate with each other to drive the adjustment screw 405 to rotate, and adjust the position of the second telescopic frame 402 on the first telescopic frame 401, so as to adjust the horizontal position of the foot pad 001, correct the child's walking state, gradually correct the deformity, and restore the normal foot shape and function. At the same time, since the child is in the development stage, the second telescopic frame 402 can be moved on the first telescopic frame 401 to facilitate the growth and development of the child.

[0024] The dynamic trigger component 003 includes a folding airbag 301, which is arranged inside the foot pad 001. The bottom end of the folding airbag 301 is fixedly connected to a pressing pad 302. The pressing pad 302 has a ventilation groove 303 inside. The ventilation groove 303 is connected to the folding airbag 301. A pressure sensor 304 is installed on the top of the folding airbag 301.

[0025] When a child walks or stands, the pressing pad 302 first contacts the ground and contracts toward the inside of the foot pad 001, transferring the pressure to the pressure sensor 304, and the pressure sensor 304 energizes the balance tube 110, which detects the state of the child's ankle. Due to the elastic material of the folding airbag 301, the folding airbag 301 will slowly return to its original position after being free from ground pressure, until the folding airbag 301 no longer exerts pressure on the pressure sensor 304, indicating that the child is no longer walking or standing. The balance tube 110 is powered off, and the device is configured to correct and improve the function and posture problems of the child's ankle joint when the child is walking, so as to restore or enhance the stability and mobility of the ankle joint, reduce or eliminate pain and discomfort related to the ankle joint, and improve gait and exercise effects. In the non-walking state, the foot pad 001 is in an active state and does not affect the child's daily life, thereby reducing the child's resistance and improving the safety of the device.

[0026] A balance tube 110 is arranged inside the foot pad 001. A group of metal contact points 120 are arranged at both ends of the balance tube 110. Each group of metal contact points 120 is provided with two metal contact points. The two metal contact points 120 are symmetrically distributed about the central bearing of the balance tube 110. Mercury 130 is arranged inside the balance tube 110. The input end of the balance tube 110 is set as a pressure sensor 304.

[0027] When the mercury 130 is located between the two sets of metal contact points 120, it means that the child is in a balanced state when walking, and the two motors 430 will not start at this time. When the mercury 130 moves to a higher position under the influence of gravity, it means that the child's posture is incorrect. Until the mercury 130 contacts the two metal contact points 120 at one end, it means that the child is in a state of foot eversion or foot inversion. The balance tube 110 is immediately energized and starts to start the motor 430 corresponding to its direction, so that the motor 430 adjusts the second telescopic frame 402 to the first The first telescopic frame 401 and the second telescopic frame 402 are distanced from each other to prevent the child's ankle from being continuously twisted and to correct the child's ankle until the mercury 130 returns to between the two sets of metal contact points 120. The arrangement is convenient for the child to have a certain amount of space for the ankle to move when the child is active. However, when the child's ankle is obviously everted or inverted, the first telescopic frame 401 and the second telescopic frame 402 on the side of the higher ankle are immediately propped up and distanced from each other so that the higher and bent ankle can return to its original position, thereby correcting the child's walking posture.

[0028] The outer side of the first telescopic frame 401 is movably connected with a first movable shaft 410 , and the first movable shaft 410 is fixedly connected to the foot pad 001 .

[0029] The outer wall of the rotating shaft 005 is movably connected with a second movable shaft 420 , and the second movable shaft 420 is fixedly connected to the leg cover 002 .

[0030] The provision of the first movable axis 410 and the second movable axis 420 facilitates children to move their ankles in a safe space, thereby reducing fear and resistance to correction in children.

[0031] The central axis of the first transmission gear 403 is located at the same position as the central axis of the first movable shaft 410 , and a motor 430 is installed on one side of the first transmission gear 403 .

[0032] Among them, the two motors 430 correspond to two groups of metal contact points 120 respectively. When the mercury 130 contacts one group of metal contact points 120, that group of metal contact points 120 will be energized through the mercury 130 and start the corresponding motor 430, so that the motor 430 can adjust and drive the second telescopic frame 402 and the first telescopic frame 401 to increase the distance and restore the bent ankle.

[0033] Embodiment 2

[0034] like Figure 7-10 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the internal rotation connection of the rotating shaft 005 is connected with a limiting tube 510, the limiting tube 510 is fixedly connected to the second telescopic frame 402, the internal sliding connection of the limiting tube 510 is connected with a sliding tube 520, the outer wall of the sliding tube 520 is movably connected with multiple groups of positioning frames 530, each group of positioning frames 530 is provided with two, and a positioning plate 540 is movably connected between the two positioning frames 530, and the external dimensions of the positioning plate 540 are consistent with the internal dimensions of the rotating shaft 005.

[0035] The outer wall of the limiting tube 510 is provided with a plurality of positioning grooves 511, and the plurality of positioning grooves 511 are distributed in a circular array about the central axis of the limiting tube 510. The rear ends of the plurality of positioning plates 540 are fixedly connected with positioning blocks 512, and the shape of the positioning blocks 512 is set to be "T"-shaped, and the outer dimensions of the positioning blocks 512 are consistent with the inner dimensions of the positioning grooves 511.

[0036] Among them, the setting of multiple positioning plates 540 can firmly fix the rotating shaft 005 to prevent loosening when the limiting tube 510 needs to be fixed, and the setting of multiple positioning blocks 512 can limit the positioning plate 540 so that the positioning plate 540 can move in a predetermined direction.

[0037] The inner wall of the rotating shaft 005 is fixedly connected with a limiting rod 550 , and the limiting rod 550 is slidably connected with the limiting tube 510 . The outer wall of the limiting rod 550 is provided with a return spring 560 , and the limiting rod 550 is movably connected with the limiting tube 510 via the return spring 560 .

[0038] Among them, the limiting rod 550 passes through the limiting tube 510, and the limiting tube 510 is positioned by the reset spring 560. The reset spring 560 gives an inward force to the limiting tube 510, pulling the limiting tube 510 inside the rotating shaft 005. At the same time, the positioning plates 540 cooperate with the limiting tube 510 and the positioning frame 530, and multiple positioning plates 540 shrink at the same time. At this time, the child can move the ankle and stretch the Achilles tendon.

[0039] The rear end of the sliding tube 520 is fixedly connected to the inclined plate 521, and a first sliding groove 522 is opened inside the inclined plate 521. A brake frame 523 is arranged at the rear end of the inclined plate 521. The brake frame 523 passes through the first sliding groove 522. A second sliding groove 524 is opened on the outer wall of the brake frame 523. The brake frame 523 is slidably connected to the limiting tube 510 through the second sliding groove 524, and a solenoid valve 525 is installed at the bottom end of the brake frame 523.

[0040] Among them, when the pressure sensor 304 receives the maximum pressure, it means that the pressing pad 302 has completely entered the foot pad 001. At this time, the foot is in an upright state. The pressure sensor 304 immediately starts the solenoid valve 525. After the solenoid valve 525 is energized, it attracts the brake frame 523 to descend along the second sliding groove 524. When the second sliding groove 524 descends, it will drive the inclined plate 521 to move backward along the first sliding groove 522. The inclined plate 521 and the sliding tube 520 move backward synchronously in the limiting tube 510, and during the backward movement, multiple positioning plates 540 are opened at the same time, and friction is applied to the rotating shaft 005 to fix the limiting tube 510 to prevent muscle tension or fatigue around the ankle joint.
