Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, and more specifically, to an auxiliary device for rehabilitation training of joints. Background Technology

[0002] The ankle joint is the most weight-bearing joint in the human body, a key joint for lower limb movement, and also the most prone to fractures. With the increasing aging of the population, ankle injuries have become a common orthopedic condition. Currently, ankle rehabilitation training mainly involves therapists manually inverting or everting, internally rotating or externally rotating the ankle. However, this method is labor-intensive. Researchers have developed ankle rehabilitation assistive training devices that use a rotating mechanism to move the ankle joint and perform rehabilitation training.

[0003] In response, Chinese patent application number CN221451638U discloses an ankle joint assisted rehabilitation training device, including a base, a resistance rod fixedly connected to the base, a sleeve rotatably connected to the resistance rod, a T-shaped tube fixedly connected to the middle of the sleeve, a lower protective shell fixedly connected to the upper end of the T-shaped tube, an upper protective shell rotatably mounted on the lower protective shell, a foot pedal fixedly connected to the upper surface of the upper protective shell, and a resistance ball fixedly connected to the middle of the lower surface of the foot pedal. This invention, through the interaction of the resistance rod and the resistance ball, allows the device to be adjusted according to the patient's rehabilitation progress via a threaded rod. This allows for the application of appropriate resistance levels during the middle and later stages of ankle joint rehabilitation training, thereby improving the rehabilitation effect of the device.

[0004] However, in actual use, when performing rehabilitation training on the entire joint, the joint cannot move forward and backward, resulting in a small range of motion and an inability to perform rehabilitation exercises on the entire joint. At the same time, the joint cannot rotate left and right.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an auxiliary device for joint rehabilitation training. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an auxiliary device for joint rehabilitation training.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a joint rehabilitation training auxiliary device, comprising a base plate, a sliding groove formed on the top surface of the base plate, a sliding plate slidably installed inside the sliding groove, a base fixedly connected to the top surface of the sliding plate, and a telescopic column installed on the front surface of the sliding plate;

[0008] The telescopic cylinder is installed on the outer surface of the telescopic column. Inside the telescopic cylinder, from left to right, a telescopic rod and a spring body are installed in sequence. The telescopic rod is provided in two sets, which are installed on the left and right sides of the spring body respectively.

[0009] A support plate is mounted on the top surface of the base. A damping shaft is mounted on the left side surface of the support plate. A mounting ring is fixedly connected to the outer surface of the damping shaft. A fixing ring is mounted on the top surface of the mounting ring.

[0010] Preferably, a first universal ball joint is installed inside the fixing ring, and a top column is provided on the top surface of the first universal ball joint.

[0011] Preferably, a top ring is fixedly connected to the top surface of the top column, and a universal ball body is provided inside the top ring.

[0012] Preferably, a connecting column is fixedly connected to the top surface of the omnidirectional ball body, and a foot pedal is installed on the top surface of the connecting column.

[0013] Preferably, a second stabilizing ring and a first stabilizing ring are installed sequentially from left to right on the outer surface of the damping shaft. A connecting plate is installed on the top surface of the first stabilizing ring, and a fixing post is installed on the left side surface of the connecting plate.

[0014] Preferably, a clamping ring is installed at the end of the fixed column away from the first stabilizing ring, and the left side of the clamping ring abuts against the right side surface of the top column.

[0015] Preferably, the second stabilizing ring has the same structure as the first stabilizing ring, and their installation positions are symmetrical.

[0016] Preferably, both the first stabilizing ring and the second stabilizing ring are sleeved and mounted on the outer surface of the damping shaft, and the first stabilizing ring and the second stabilizing ring are rotatably mounted on the surface of the damping shaft.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, by setting a sliding groove, sliding plate, base, telescopic column, telescopic cylinder, telescopic rod, spring body, support plate, damping shaft, mounting ring, fixing ring, first universal ball column, and top column, when joint rehabilitative training is required, the foot is placed on the surface of the foot pedal, and then the damping shaft is rotated. Subsequently, the foot pushes the base as a whole, and the base will drive the sliding plate to slide inside the sliding groove. The overall sliding effect is good. When the sliding plate moves, it will drive the base to move. At this time, the base will move inside the telescopic column. At this time, the base will drive the telescopic rod and spring body to compress. Thus, when the base moves, there will be elastic force from the spring body. This elastic force can make the base move with resistance, so the rehabilitation training effect is good and can train the ankle joint forward and backward. At the same time, the first universal ball column is installed inside the fixing ring. The first universal ball column can make the top column rotate, which reflects the practicality of the design.

[0019] 2. In this invention, the top ring, omnidirectional ball body, connecting column, foot pedal, first stabilizing ring, connecting plate, fixed column, clamping ring, and second stabilizing ring are configured such that when the top column cannot rotate, the second stabilizing ring and the first stabilizing ring can clamp the top column through the clamping ring, thus fixing the position of the top column and achieving a good overall fixation effect. Subsequently, when the top column needs to rotate, the first stabilizing ring and the second stabilizing ring are moved away from each other, allowing them to move on the surface of the damping shaft. This prevents the clamping ring from contacting the outer surface of the top column, enabling the top column to rotate through the design of the first omnidirectional ball column and the fixed ring. The rotation of the top column allows for a wider range of rotation between the foot pedal and the top ring, resulting in a larger range of motion and better training effects, demonstrating the functionality of the design.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Reference Figures 1 to 5 The following is a further description of an embodiment of the joint rehabilitation training aid device of the present invention.

[0032] This invention provides an auxiliary device for rehabilitation training of joints. The telescopic rod 7, damping shaft 10, first universal ball column 13 and foot pedal 18 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a base plate 1, a sliding groove 2 is provided on the top surface of the base plate 1, a sliding plate 3 is slidably installed inside the sliding groove 2, a base 4 is fixedly connected to the top surface of the sliding plate 3, and a telescopic column 5 is installed on the front surface of the sliding plate 3.

[0033] Telescopic cylinder 6 is installed on the outer surface of telescopic column 5. The telescopic cylinder 6 is installed from left to right inside the telescopic cylinder 6 with telescopic rod 7 and spring body 8. There are two sets of telescopic rod 7, which are installed on the left and right sides of spring body 8 respectively.

[0034] A support plate 9 is mounted on the top surface of the base 4. A damping shaft 10 is mounted on the left side surface of the support plate 9. A mounting ring 11 is fixedly connected to the outer surface of the damping shaft 10. A fixing ring 12 is mounted on the top surface of the mounting ring 11. A first universal ball column 13 is installed inside the fixing ring 12. A top column 14 is provided on the top surface of the first universal ball column 13. When joint rehabilitative exercises are required, the foot is placed on the surface of the foot pedal 18, and the damping shaft 10 is rotated. Subsequently, the base 4 is pushed as a whole by the foot, and the base 4 will slide. The plate 3 slides inside the sliding groove 2, and the overall sliding effect is good. When the sliding plate 3 moves, it will drive the base 4 to move. At this time, the base 4 will move inside the telescopic column 5. The base 4 will drive the telescopic rod 7 and the spring body 8 to compress. As a result, the base 4 will have the elastic force of the spring body 8 when it moves. The elastic force can make the base 4 move with resistance, so the rehabilitation training effect is good and can train the front and back of the ankle joint. At the same time, the first universal ball column 13 is installed inside the fixed ring 12. The top column 14 can be rotated through the first universal ball column 13.

[0035] A top ring 15 is fixedly connected to the top surface of the top column 14. A universal ball body 16 is provided inside the top ring 15. A connecting column 17 is fixedly connected to the top surface of the universal ball body 16. A foot pedal 18 is installed on the top surface of the connecting column 17. By installing the universal ball body 16 and the connecting column 17 inside the top ring 15, the foot pedal 18 can be rotated.

[0036] A second stabilizing ring 23 and a first stabilizing ring 19 are sequentially mounted on the outer surface of the damping shaft 10 from left to right. A connecting plate 20 is mounted on the top surface of the first stabilizing ring 19, and a fixing post 21 is mounted on the left side surface of the connecting plate 20. A clamping ring 22 is mounted on the end of the fixing post 21 away from the first stabilizing ring 19, and the left side of the clamping ring 22 abuts against the right side surface of the top post 14. The second stabilizing ring 23 has the same structure as the first stabilizing ring 19, and their installation positions are symmetrical. Both the first stabilizing ring 19 and the second stabilizing ring 23 are sleeved and mounted on the outer surface of the damping shaft 10. The first stabilizing ring 19 and the second stabilizing ring 23 are rotatably mounted on the surface of the damping shaft 10. When the top post 14 cannot rotate... At this time, the second stabilizing ring 23 and the first stabilizing ring 19 can clamp the top column 14 through the clamping ring 22, which can clamp and fix the position of the top column 14, and the overall fixation effect is good. Then, when the top column 14 needs to rotate, by moving the first stabilizing ring 19 and the second stabilizing ring 23 away from each other, it moves on the surface of the damping shaft 10, so that the clamping ring 22 will not touch the outer surface of the top column 14. Thus, the top column 14 can rotate through the design of the first universal ball column 13 and the fixing ring 12. The rotation of the top column 14 can increase the range of rotation between the foot pedal 18 and the top ring 15, thereby increasing the range of motion and improving the training effect.

[0037] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical support. During use, when joint rehabilitative exercises involving forward and backward movement are required, the operator places their foot on the surface of the foot pedal 18 and rotates the damping shaft 10. The foot then pushes the base 4, causing the sliding plate 3 to slide within the sliding groove 2. The overall sliding effect is good. As the sliding plate 3 moves, it moves the base 4, which then moves within the telescopic column 5. This causes the telescopic rod 7 and the spring body 8 to compress, resulting in spring force on the base 4 during movement. This spring force provides resistance during the base 4's movement, thus improving the effectiveness of the rehabilitation training. This invention provides training for the front and back of the ankle joint. A first universal ball joint 13 is installed inside the fixing ring 12, allowing the top column 14 to rotate. When the top column 14 cannot rotate, the second stabilizing ring 23 and the first stabilizing ring 19 clamp the top column 14 via the clamping ring 22, effectively fixing its position. The overall fixation effect is good. Subsequently, when the top column 14 needs to rotate, the first stabilizing ring 19 and the second stabilizing ring 23 are moved away from each other, allowing it to move on the surface of the damping shaft 10. This prevents the clamping ring 22 from contacting the outer surface of the top column 14, enabling the top column 14 to rotate via the design of the first universal ball joint 13 and the fixing ring 12. This completes the working principle of the invention.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
