Description

Technical Field

[0001] This utility model relates to a rehabilitation training device, specifically a quick-release flexible footrest mechanism for rehabilitation training, belonging to the technical field of rehabilitation training mechanical parts. Background Technology

[0002] Many rehabilitation training devices utilize foot braces to restrain the patient's feet, such as the rehabilitation training machine disclosed in Chinese patent application CN113057855A, the lower limb rehabilitation training device disclosed in CN118058946A, and CN116570469A. A disclosed lower limb rehabilitation training device involves a footrest mechanism. Existing footrest mechanisms are generally fixed, resembling a shoe shape. The patient's foot is secured with straps or Velcro after insertion, making it impossible to adjust to different foot sizes and resulting in poor adaptability to the user's foot shape. Some footrest mechanisms are adjustable in size, but this makes them complex and sometimes requires specialized tools. In rehabilitation training, besides adjusting the size of the footrest to suit different patients, individual differences and the complexity of leg and foot deformities caused by the disease mean that many patients may have different optimal foot placement positions. Current rehabilitation training devices rarely offer quick adjustments to the footrest mechanism's position. Furthermore, in multifunctional rehabilitation training devices, some training functions may be hindered by the footrest, requiring its removal; however, quick-disassembly structures are rare in existing devices. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in the foot support mechanism of existing rehabilitation training equipment and to provide a quick-release flexible foot support mechanism for rehabilitation training.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A quick-release flexible footrest mechanism for rehabilitation training includes two foot plates, on which an elastic quick-release adjustable footrest device is installed. The elastic quick-release foot limiting device includes an elastic pin, which includes an outer cylinder. The lower opening of the outer cylinder has a limiting shoulder. A thin rod is fixedly connected to the upper end face of the T-shaped pin, and a spring passes through the thin rod. A top cover with a central hole is provided at the upper end of the outer cylinder. The T-shaped pin is rotatably disposed in the outer cylinder. The thin rod of the elastic pin passes through the central hole of the top cover. A spring passes through the thin rod on the upper part of the top cover, and the thin rod on the upper part of the spring... A handle is fixedly connected. The vertical side of the T-shaped pin passes through the shoulder of the shaft and extends out of the outer cylinder. A horizontal pin is fixedly connected to the lower end of the T-shaped pin. Two arrayed limiting holes are opened at the corresponding positions of the feet on the chassis. Cross holes are machined in the limiting holes. One direction of the cross holes is a long-wide hole and the other direction is a long-narrow hole. The horizontal pin can pass through the long-wide hole but cannot pass through the long-narrow hole. A pair of front limiting pins and a pair of rear limiting pins are respectively set on the left and right sides of the two arrayed limiting holes. A strap fixing plate is fixedly connected to the outer cylinder of the pair of front limiting pins. Straps are connected to the two strap fixing plates. Heel supports are connected to the outer cylinder of the pair of rear limiting pins.

[0005] Furthermore, the upper half of the limiting hole in the depth direction is a circular hole, and the lower half is a cross hole.

[0006] Furthermore, the two foot plates are located on a single, integrated base plate.

[0007] Furthermore, the upper cover is fixedly connected to the upper port of the outer cylinder, and the upper cover limits the upper part of the T-pin.

[0008] Furthermore, the upper cover is pressed onto the upper port of the outer cylinder, and the T-shaped pin at the lower part of the outer cylinder has a limiting part that cannot pass through the hole at the shoulder.

[0009] The positive and organic technical advantages of this utility model are: the footrest mechanism is simple, and it can be quickly disassembled and adjusted to meet the requirements of different users.

[0014] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0015] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: base plate; 2: top cover; 3: outer cylinder; 4: limiting hole in the first array; 5: limiting hole in the second array; 6: handle; 7: spring; 8: strap; 9: strap fixing plate; 10: heel support; 11: T-pin; 12: thin rod; 13: vertical side of T-pin; 14: shoulder; 15: horizontal pin; 401: round hole; 402: cross hole; 403: long and wide hole; 404: long and narrow hole.

[0016] A quick-release flexible footrest mechanism for rehabilitation training includes two foot plates. In this embodiment, the two foot plates are located on a single integral base plate 1. On the base plate 1, corresponding parts of both feet are equipped with elastic quick-release adjustable footrest devices. The elastic quick-release foot limiting device includes an elastic pin. The elastic pin includes an outer cylinder 3 with a limiting shoulder 14 at its lower opening. A thin rod 12 is fixedly connected to the upper end face of a T-shaped pin 11, and a spring 7 passes through the thin rod 12. A top cover 2 with a central hole is provided at the upper end of the outer cylinder. The T-shaped pin is rotatably positioned within the outer cylinder. The thin rod of the elastic pin passes through the central hole of the top cover, with a gap between the thin rod and the central hole, allowing the thin rod to slide vertically relative to the central hole. A handle 6 is fixedly connected to the thin rod above the spring. The vertical side 13 of the T-shaped pin extends out of the outer cylinder after passing through the shoulder. A horizontal pin 15 is fixedly connected to the lower end of the T-shaped pin. Two arrayed limiting holes are provided on the corresponding part of the foot on the chassis. In the figure, the two arrayed limiting holes are the limiting holes in the first array shown in 4 and the limiting holes in the second array shown in 5. The limiting holes are machined with cross holes. In this embodiment, the upper half of the limiting hole in the depth direction is a round hole 401 and the lower half is a cross hole 402. One direction of the cross hole is a long and wide hole 403 and the other direction is a long and narrow hole 404. The horizontal pin can pass through the long and wide hole but cannot pass through the long and narrow hole. A pair of front limiting pins 16 and a pair of rear limiting pins 17 are respectively provided on the left and right sides of the two arrayed limiting holes. A strap fixing plate 9 is fixedly connected to the outer cylinder of the pair of front limiting pins. Straps 8 are connected to the two strap fixing plates. The straps can be fastened with Velcro. A heel support 10 is connected to the outer cylinder of the pair of rear limiting pins. The heel support is preferably a flexible support.

[0017] In this invention, to achieve positioning of the T-pin, the upper cover can be configured in one of the following ways: First, the upper cover is fixedly connected to the upper port of the outer cylinder, and the upper cover limits the upper part of the T-pin; Second, the upper cover is pressed onto the upper port of the outer cylinder, and the T-pin at the lower part of the outer cylinder has a limiting part that cannot pass through the hole in the shoulder area. In this embodiment, the limiting part can utilize a horizontal pin. When the horizontal pin is engaged in the long, narrow hole, the handle is in a back-and-forth direction, thus reducing the possibility of interference with the foot.

[0018] In this footrest mechanism, the distance between a pair of front limiting pins and a pair of rear limiting pins, which are fitted into different limiting holes, can accommodate the length of different patients' feet. Adjusting the distance between the two limiting pins in the pair of front limiting pins can accommodate the width of different patients' feet. The spring pin can be disengaged from the limiting hole by pressing and rotating 90 degrees. After being inserted into the long and wide hole, it can be rotated 90 degrees to limit the horizontal pin through the long and narrow hole, so that the spring pin is engaged in the limiting hole. Adjustment and disassembly when not in use are very convenient.

[0019] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
