Description

Technical Field

[0001] This utility model relates to the field of exercise equipment technology, and in particular to a foot pedal device for diabetes rehabilitation exercise. Background Technology

[0002] In the field of diabetes rehabilitation, exercise pedals serve as crucial equipment to assist patients in rehabilitation training, and their effectiveness directly impacts the rehabilitation process. With the increasing number of diabetes patients, the functional needs of rehabilitation exercise pedals are becoming increasingly diverse, placing higher demands on the convenience and adaptability of these devices. However, existing diabetes rehabilitation exercise pedals still have many shortcomings in practical applications, making it difficult to fully meet the personalized needs of patients.

[0003] Existing rehabilitation training equipment, such as the rehabilitation training mechanism and equipment disclosed in CN213131759U, uses a frame, a first foot pedal, a second foot pedal, and a transmission component to work together, so that one foot pedal can drive the other foot pedal to move in the opposite direction, thereby helping patients to perform leg coordination training. However, existing foot pedal devices have the problem of not being able to quickly replace the foot pedals. When the foot pedal parts are damaged or need to be cleaned or replaced, it is often necessary to use professional tools and spend a lot of time on disassembly and installation, which seriously affects the efficiency of use. At the same time, the device lacks the function of adjustment for different foot sizes, and cannot adapt to the foot sizes of different patients. This not only reduces the comfort of patients when using it, but may also affect the rehabilitation training effect due to poor fit, thus restricting the further promotion and application of rehabilitation exercise foot pedal devices. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing foot pedal devices cannot be quickly disassembled and replaced. When the foot pedal parts are damaged or need to be cleaned or replaced, it is often necessary to use professional tools and spend a lot of time to disassemble and install them, which seriously affects the efficiency of use. At the same time, the device lacks the function of adjusting for different foot sizes and cannot adapt to the foot sizes of different patients. This not only reduces the comfort of patients when using it, but may also affect the rehabilitation training effect due to poor fit. These shortcomings restrict the further promotion and application of rehabilitation exercise foot pedal devices. Therefore, a diabetes rehabilitation exercise foot pedal device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foot pedal device for diabetes rehabilitation includes a frame, with connecting arms rotatably arranged on both sides of the frame. One end of each connecting arm has a mounting hole, and a replacement shaft is provided in the mounting hole.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 A foot pedal device for diabetes rehabilitation exercise includes a frame 1. The frame 1 is a prior art in the field of this technology. It drives the connecting arms 2 on both sides to rotate in opposite directions to facilitate the lower limb rehabilitation training of diabetic patients, so it will not be described in detail.

[0028] Connecting arms 2 are rotatably mounted on both sides of the frame 1. One end of the connecting arm 2 is provided with a mounting hole 3. A replacement shaft 4 is provided in the mounting hole 3. A quick locking mechanism 5 is provided at the tail end of the replacement shaft 4. The quick locking mechanism 5 includes a sliding hole 51, a spring 52 and a limiting protrusion 53. The sliding hole 51 is opened on the outer wall of the tail end of the replacement shaft 4. One end of the spring 52 is fixedly installed in the sliding hole 51, and the other end of the spring 52 is fixedly installed on the limiting protrusion 53. The limiting protrusion 53 is slidably installed in the sliding hole 51. The replacement shaft 4 can be quickly installed and removed from the mounting hole 3 through the quick locking mechanism 5.

[0029] The quick-locking mechanism 5 adopts a spring 52-driven limit protrusion 53 design, which enables the replacement of shaft 4 to be completed with one hand, significantly improving maintenance efficiency. The depth of the sliding hole 51 is precisely calculated to ensure that the limit protrusion 53 is fully retracted when the spring 52 is compressed, avoiding installation interference. When released, the protrusion pops out by 3-5mm, providing reliable mechanical interlock.

[0030] A T-head 6 is fixedly installed at the first end of the replacement shaft 4. A front foot pedal 7 is slidably installed on the T-head 6. A length adjustment mechanism 8 is installed on the side of the front foot pedal 7 away from the tip. The length adjustment mechanism 8 includes a capped screw 81, a limiting rod 82, a threaded hole 83, and a limiting hole 84. The capped screw 81 is rotatably installed on the front foot pedal 7, and the limiting rod 82 is fixedly installed on the front foot pedal 7. The capped screw 81 and the limiting rod 82 are located on the same side. The threaded hole 83 and the limiting hole 84 are both located on the rear foot pedal 9. The capped screw 81 is threadedly connected to the threaded hole 83, and the limiting rod 82 is slidably engaged with the limiting hole 84. The rear foot pedal 9 is installed on the front foot pedal 7 through the length adjustment mechanism 8.

[0031] Among them, the capped screw 81 adopts a trapezoidal thread and is matched with the anodized threaded hole 83 to achieve precise displacement; the limit rod 82 is hard chrome plated and has a tight fit with the limit hole 84 to ensure no radial swing during adjustment; the mechanism supports a continuous adjustment range of 50-300mm and can be adapted to 95% of adult foot lengths.

[0032] Furthermore, a bearing is fixedly installed inside the mounting hole 3 by welding, and a limit block 10 is fixedly installed inside the bearing. A limit groove 11 adapted to the limit block 10 is opened on the outer wall of the tail end of the replacement shaft 4, and the limit block 10 and the limit groove 11 slide together.

[0033] The NSK 6200ZZ bearing embedded in the mounting hole 3 is designed with a dovetail groove for the limiting block 10 and the limiting groove 11. The limiting block 10 is carburized and quenched, and its contact area with the limiting groove 11 is over 80%, effectively suppressing micro-displacement during rotation and providing a service life of over 100,000 revolutions.

[0034] Furthermore, a T-shaped groove 13 is provided at the bottom of the front foot pedal 7, and the T-shaped head 6 slides in conjunction with the groove 13.

[0035] Among them, the T-head 6 is made of 7075 aviation aluminum alloy CNC machined and the fit tolerance with the groove 13 is controlled within ±0.1mm to achieve smooth sliding without shaking. The groove 13 is embedded with a nylon wear-resistant bushing, which reduces the coefficient of friction and eliminates metal noise.

[0036] Furthermore, a threaded hole 12 is provided at the front of the T-head 6, and a locking plate 14 is fixedly provided at the bottom of the front foot pedal 7. A locking bolt 15 is slidably provided on the locking plate 14. The locking bolt 15 passes through the locking plate 14 and is threadedly connected to the threaded hole 12. The front foot pedal 7 is connected to the replacement shaft 4 through the locking bolt 15.

[0037] Among them, the front foot pedal 7 and the rear foot pedal 9 are made of glass fiber reinforced PP material, which reduces the weight by 35% while maintaining a dynamic load capacity of 150kg, and the contact surface is designed with 3mm deep anti-slip texture.

[0038] Working principle:

[0039] In use, first place the frame 1 stably, and have the patient sit on the appropriate chair with their legs on either side of the frame. Press the limiting protrusion 53 with one hand to compress the spring 52, causing the limiting protrusion 53 to retract completely into the sliding hole 51. Insert the tail end of the replacement shaft 4 into the mounting hole 3 of the connecting arm 2 on the frame 1, release the limiting protrusion 53, and the spring 52 will spring open, causing the limiting protrusion 53 to extend and engage with the inner wall of the mounting hole 3, achieving quick installation. To disassemble, simply press the protrusion to pull it out.

[0040] After installing and replacing shaft 4, adjust the length of the foot pedal according to the patient's foot length. Rotate the capped screw 81, and use the cooperation between the trapezoidal thread and the threaded hole 83 to move the rear foot pedal 9 along the limiting rod 82. The limiting rod 82 and the limiting hole 84 are tightly engaged to ensure that there is no radial oscillation during adjustment.

[0041] After adjustment, the front foot pedal 7 is fitted onto the end of the replacement shaft 4 through the sliding fit between the T-head 6 and the groove 13. Then, the locking bolt 15 is tightened to connect it with the threaded hole 12, thus fixing the front foot pedal 7. The patient steps on the front foot pedal 7 and the rear foot pedal 9 with both feet. The anti-slip texture of the glass fiber reinforced PP material provides grip. The patient can then perform lower limb rehabilitation training for diabetes by rotating the connecting arm 2 through their legs.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
