Technical Field

[0001] The present invention relates to the technical field of walking assistance devices, and specifically to a walking assistance device for orthopedic rehabilitation. Background Art

[0002] A walking assistance device for orthopedic rehabilitation refers to a device specifically designed to assist orthopedic patients in walking and restoring mobility during the rehabilitation process. When a patient is unable to walk normally due to injury, surgery, or balance disorders, it can provide the necessary support, stability, and mobility for the patient. Therefore, it is widely used in elderly patients, orthopedic postoperative patients, and patients with balance disorders. A walking aid is also a type of walking assistance device that provides additional stability and seat support functions. When the walking aid is used to assist the patient in walking, most patients need to continuously lift it to ensure walking displacement. However, this operation is very time-consuming and laborious, increasing the patient's labor load and having poor practicability.

[0003] In order to overcome the above defects, in Prior Art 1 (a Chinese patent with application number CN202323417377.0 and application date December 15, 2023), in a walking assistance device, by changing the user's hand-holding position, the movement of the walking assistance device can be achieved, avoiding the load caused to the user by continuously lifting the traditional walking assistance device, and at the same time, the walking assistance device can be fixed, laying a foundation for the user to rest in a fixed position, facilitating the promotion and use of the product. And in Prior Art 2 (a Chinese patent with application number CN201721900351.3 and application date December 29, 2017), in a walking assistance device, it has an automatic walking mode and an electric walking mode, and automatically switches between the two modes according to whether the hub motor is in contact with the workpiece surface, facilitating the user to select the operation mode according to different application scenarios. It also includes a body folding structure, which is convenient for wheelchair patients to enter the walking assistance device, and at the same time increases the mobility of the walking assistance device and its passing ability in a narrow space.

[0004] Although the prior art can improve the usability of the walking assistance device, thereby reducing the user's load, there is no auxiliary limiting mechanism to position and fix the moved assistance device during the patient's use of the walking assistance. It can only be manually operated to position and prevent slipping of the moved assistance device, which is very time-consuming and laborious and has poor practicability. Therefore, we propose a walking assistance device for orthopedic rehabilitation to solve the problems raised above. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention provides the following technical solutions, a walking assistance device for orthopedic rehabilitation: Embodiment 1. To solve the problem that there is no auxiliary limiting mechanism in the existing patients to position and fix the auxiliary device after movement during the use of walking assistance, and only manual operation of the positioning mechanism can be used to position and prevent slipping of the auxiliary device after movement, which is very time-consuming and laborious and has poor practicability. It discloses: a walker 1, and side rods 2 for support are arranged on both sides of the top of the walker 1, and a protective rod 29 is arranged at the rear side of the top of the walker 1. Armrests 4 are slidably installed through both sides of the walker 1, and protective sleeves 5 are nested on the outer sides of the two armrests 4; Mounting seats 9 are positioned and installed on both inner ends of the walker 1, and rotating shafts 10 are rotatably installed at the inner ends of the two mounting seats 9, and the outer end of the left rotating shaft 10 extends through the outside of the left mounting seat 9, and a seat board 3 is connected through the outside of the rotating shaft 10. The seat board 3 is rotatably installed inside the walker 1, and a pressing rod 11 is installed through the left end of the rotating shaft 10; Transmission shafts 21 are rotatably installed on both sides of the bottom of the walker 1, and the structures of the two transmission shafts 21 are the same, and movable wheels 8 are installed at both ends of the two transmission shafts 21. At the same time, a clamping seat 20 is clamped and connected to the outside of the two left transmission shafts 21.

[0020] On the outer side of the left end armrest 4, a lifting rod 12 is provided, and a mounting plate 13 is installed at the bottom end of the lifting rod 12. On both sides of the mounting plate 13, racks 14 are provided, and on the outer sides of the two racks 14, a driving gear 17 is meshed and connected. The two driving gears 17 are rotatably installed on the left side of the walking aid 1, and the two driving gears 17 are symmetrically arranged about the horizontal center line of the walking aid 1. On the outer sides of the two driving gears 17, a toothed plate 15 is meshed and connected. At the top ends of the two toothed plates 15, a connecting frame 16 is connected. At both ends of the interior of the two connecting frames 16, a limiting rod 19 is slidably installed through. Every two limiting rods 19 are positioned and installed on both sides of the walking aid 1. At the bottom ends of the two connecting frames 16, a positioning rod 18 is installed. At the bottom ends of the two positioning rods 18, a clamping seat 20 is installed. At both ends of the top of the walking aid 1, two first return springs 22 are installed. Every two first return springs 22 have the same structure, and at the top ends of every two first return springs 22, an armrest 4 is connected.

[0021] As Figures 1-6 shown, when the patient uses the walking aid 1 for walking assistance, the patient's hands are placed on the outer sides of the two armrests 4 for pressing. At this time, the two armrests 4 will move downward through the extrusion force of the patient's hands. Subsequently, the two armrests 4 will drive the lifting rod 12 to drive the two driving gears 17 to rotate simultaneously through the mounting plate 13 and the rack 14. Because the two driving gears 17 are meshed and connected with the two toothed plates 15 on the outer sides, at this time, the connecting frame 16 connected to one end of the two toothed plates 15 can be driven to move upward in position through the two limiting rods 19, so that the two connecting frames 16 can drive the clamping seat 20 to move upward in position through the positioning rod 18 at the same time, so that the two clamping seats 20 are separated from the two transmission shafts 21, which facilitates the patient to move the walking aid 1 for walking assistance and reduces the patient's usage burden. When the use of the walking aid 1 is ended, the two first return springs 22 will elastically reset the two armrests 4 after being squeezed and lowered through their own elastic force. At this time, the two lifting rods 12 can be driven to move upward in position for reset at the same time, so that the two driving gears 17 can drive the clamping seat 20 connected to the bottom ends of the two positioning rods 18 to move downward in position, so that the two clamping seats 20 clamp and position the two transmission shafts 21, avoiding the phenomenon of dislocation and deviation during the later walking assistance of the walking aid 1, and the stability is better.

[0022] Embodiment 2, different from Embodiment 1, can cushion and buffer the patient's hands when the walking aid 1 cooperates with the patient for walking assistance, avoid the phenomenon of soreness and swelling of the patient's hands after long-term use of the walking aid 1, improve the use comfort of the walking aid 1, and disclose: At both bottom ends of the two armrests 4, damping rods 6 are connected through buffer springs 7. The four damping rods 6 have the same structure, and the bottom ends of the four damping rods 6 are connected to the walking aid 1.

[0023] As Figures 1-7 shown, while the patient's both hands press the two armrests 4 to move downward in position, the two armrests 4 will squeeze the two damping rods 6 to perform buffered extrusion through the buffer springs 7. The seismic buffer performance between the two armrests 4 and the walking aid 1 can be increased through the two damping rods 6, avoiding the phenomenon of soreness and swelling of the patient's both hands after long-term use of the walking aid 1, improving the comfort of using the walking aid 1. Finally, the positions of the two armrests 4 after being pressed and lowered can be reset by the elastic force of the two first reset springs 22 for repeated pressing and use in the later stage, with better practicability.

[0024] Embodiment 3, different from Embodiment 2, the seat board 3 can be flipped and swung in the later stage when the patient uses the walking aid 1 for a long time, so as to facilitate the patient to sit and rest, improving the comfort of using the walking aid 1, and discloses: A second reset spring 23 is wound and connected to the outer side of the pressing rod 11, and one end of the second reset spring 23 is connected to the inner wall of the rotating shaft 10. A limiting block 24 is slidably installed through the pressing spring 25 inside the left side of the rotating shaft 10, and one end of the limiting block 24 extends through the rotating shaft 10 into the inside of the seat board 3. First limiting grooves 26 and second limiting grooves 27 are symmetrically opened at both ends inside the seat board 3. Among them, the first limiting groove 26, the second limiting groove 27 and the limiting block 24 form a clamping mechanism. One end of the pressing rod 11 is connected with a pull rope 28, and one end of the pull rope 28 is connected with the limiting block 24 through a guide wheel.

[0025] As Figures 1-10 shown, when the patient needs to rest and sit, only need to squeeze the pressing rod 11 to move through the second reset spring 23 inside the rotating shaft 10. At this time, the moving pressing rod 11 will drive the pull rope 28 to pull the limiting block 24 to contract and move through the guide wheel, so that the limiting block 24 is separated from the second limiting groove 27, so that the limiting block 24 can contract and move into the inside of the rotating shaft 10, and then it can conveniently drive the seat board 3 to rotate and flip outside the rotating shaft 10. After the seat board 3 rotates and flips to a suitable position, release the pressing rod 11. At this time, the second reset spring 23 will perform elastic reset on the pressed and contracted pressing rod 11 through its own elastic force. Subsequently, the pressing spring 25 will also automatically eject the limiting block 24 into the inside of the first limiting groove 26 through its own elastic force, so as to realize the position limiting and fixing of the flipped and rotated seat board 3, avoiding the phenomenon of loosening and falling off of the seat board 3 during later use, with better stability. On the contrary, squeezing the pressing rod 11 to contract and move can drive the seat board 3 to flip and reset, so that the limiting block 24 extends through to the inner side of the second limiting groove 27 for clamping and positioning, and the operation is more time-saving and labor-saving, thus completing a series of work.

[0026] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
