Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a retractable footrest device for rehabilitation training equipment. Background Technology

[0002] In the field of modern medical rehabilitation, rehabilitation training equipment plays a crucial role. However, existing rehabilitation training equipment has many shortcomings in footrest design, such as being fixed and non-adjustable, making it difficult to adapt to the needs of different patients. This limits the effectiveness of rehabilitation training for patients to some extent and increases the operational difficulty for medical staff. Therefore, there is an urgent need for a retractable footrest device for rehabilitation training equipment that can be flexibly adjusted to meet the needs of different patients. Utility Model Content

[0003] To address the shortcomings of existing rehabilitation training equipment in terms of footrest design, such as fixed and non-adjustable footrests that are difficult to adapt to the needs of different patients, this application provides a retractable footrest device for rehabilitation training equipment.

[0004] The retractable footrest device for rehabilitation training equipment provided in this application adopts the following technical solution:

[0005] A retractable footrest device for rehabilitation training equipment includes a fixed base plate, a front foot plate, and a rear foot plate. An adjustment mechanism is installed on the bottom outer wall of the fixed base plate to adjust the distance between the front foot plate and the rear foot plate.

[0006] The adjustment mechanism includes a drive arm rotatably connected to the middle outer wall of the bottom of the fixed base plate via a rotating shaft. The two ends of the drive arm are hinged with connecting rods. The bottom outer walls of the front foot plate and the rear foot plate are both fixedly connected with connecting columns. The end of the connecting rod away from the drive arm is rotatably connected to the connecting column.

[0007] Preferably, the adjustment mechanism further includes a worm gear fixedly connected to the middle outer wall of the bottom of the drive arm, and a worm is rotatably connected to the bottom outer wall of the fixed base plate through two bearing seats, the worm meshing with the worm gear.

[0008] Preferably, one end of the worm gear passes through a bearing and is fixedly connected to a handle.

[0009] Preferably, the top outer walls of the front foot plate and the rear foot plate are provided with sliding grooves, and the two outer walls of the fixed base plate are fixedly connected with sliders, which are slidably connected to the inner walls of the sliding grooves.

[0010] Preferably, the outer walls of the front foot plate and the rear foot plate opposite each other are provided with multiple limiting grooves, and multiple limiting rods are fixedly connected to the outer walls of both sides of the fixed base plate, and the limiting rods are slidably connected to the inner walls of the limiting grooves.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The retractable footrest device of this utility model can flexibly adjust the overall length of the footrest through the adjustment mechanism, thereby adapting to the needs of different patients and improving the rehabilitation training effect;

[0013] 2. In the adjustment mechanism, the meshing transmission of the worm gear and worm wheel has self-locking properties, which can lock the position of the front foot plate and the rear foot plate after the overall length of the fixed base plate, the front foot plate and the rear foot plate are adjusted, thereby enhancing the stability of the footrest and ensuring the safety of the patient during use.

[0014] 3. The overall structure is simple and easy to operate, reducing the difficulty of operation for medical staff. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a retractable footrest device for rehabilitation training equipment. (See also...) Figure 1-3 A retractable footrest device for rehabilitation training equipment includes a fixed base plate 1, a front foot plate 2 and a rear foot plate 3. An adjustment mechanism is installed on the bottom outer wall of the fixed base plate 1 to adjust the distance between the front foot plate 2 and the rear foot plate 3.

[0021] The adjustment mechanism includes a drive arm 9 rotatably connected to the outer wall of the bottom middle of the fixed base plate 1 via a rotating shaft 8. The two ends of the drive arm 9 are hinged with connecting rods 11. The outer walls of the bottom of the front foot plate 2 and the rear foot plate 3 are both fixedly connected with connecting columns 12. The end of the connecting rod 11 away from the drive arm 9 is rotatably connected to the connecting column 12.

[0022] The adjustment mechanism also includes a worm gear 10 fixedly connected to the middle outer wall of the bottom of the drive arm 9. The bottom outer wall of the fixed base plate 1 is rotatably connected to a worm 14 through two bearings 13. The worm 14 meshes with the worm gear 10. One end of the worm 14 passes through a bearing 13 and is fixedly connected to a handle 15.

[0023] The top outer walls of the front foot plate 2 and the rear foot plate 3 are provided with grooves 4. The outer walls of both sides of the fixed base plate 1 are fixedly connected with sliders 5. The sliders 5 are slidably connected to the inner wall of the grooves 4. The sliding connection between the sliders 5 and the grooves 4 can fill the gap between the front foot plate 2, the rear foot plate 3 and the fixed base plate 1, making the overall connection of the footrest tighter.

[0024] Multiple limiting grooves 6 are provided on the outer walls of the front foot plate 2 and the rear foot plate 3, and multiple limiting rods 7 are fixedly connected to the outer walls of both sides of the fixed base plate 1. The limiting rods 7 are slidably connected to the inner walls of the limiting grooves 6. The front foot plate 2 and the rear foot plate 3 are limited by the sliding connection between the limiting grooves 6 and the limiting rods 7 to prevent the distance between the front foot plate 2 and the rear foot plate 3 from being too long.

[0025] The implementation principle of the retractable footrest device for rehabilitation training equipment in this application embodiment is as follows: When adjustment is required, the handle 15 is turned, the handle 15 drives the worm gear 14 to rotate, the worm gear 14 drives the worm wheel 10 meshing with it to rotate, and when the worm wheel 10 rotates, it drives the drive arm 9 to rotate. When the drive arm 9 rotates, its two ends synchronously pull the two connecting rods 11 to move inward. The two connecting rods 11 rotate in coordination, and through the connecting column 12, they drive the front foot plate 2 and the rear foot plate 3 to move closer to the fixed base plate 1, thus shortening the overall length of the footrest.

[0026] Similarly, when the handle 15 is rotated in the opposite direction, the two connecting rods 11 are pushed outward through the two ends of the drive arm 9. The two connecting rods 11 rotate in coordination and push the front foot plate 2 and the rear foot plate 3 away from each other through the connecting column 12, which increases the length of the footrest, makes the footrest adaptable to the needs of different patients, and improves the effect of rehabilitation training.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
