Description

Technical Field

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

[0002] Foot exercise devices are needed to prevent thrombosis. Their core function is to address the slow blood circulation in the lower limbs of people who sit or lie down for long periods by simulating active foot movements. This reduces the risk of thrombosis at its source. The foot exercise device specifically addresses this problem by using a mechanical structure to drive the foot in rhythmic movements, such as repeated flexion, extension, rotation, or compression. This passive movement effectively replaces the muscle work involved in active walking, continuously compressing leg blood vessels and promoting venous blood return to the heart, preventing blood from stagnating in the lower limb vessels for extended periods. Simultaneously, the accelerated blood circulation from the device reduces the accumulation and adhesion of blood components, fundamentally reducing the impact of the two key factors in thrombosis—slow blood flow and a hypercoagulable state. It is particularly suitable for people with limited mobility, such as those recovering from surgery, those who are bedridden for long periods, or those who sit for extended periods at work.

[0003] However, existing foot exercise devices for preventing blood clots have the following drawbacks:

[0004] (1) When common equipment is put away after use, it usually requires a lot of storage space, which reduces the practicality of the device;

[0005] (2) The seats of traditional equipment are difficult to adjust in height, making it difficult to adapt to users of different heights and body types. This can easily lead to improper posture during use, which not only affects the exercise effect but may also cause discomfort in the waist and legs.

[0006] Therefore, this invention provides a foot exercise device for preventing thrombosis. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical foot exercise device for preventing thrombosis, which solves the problems mentioned in the background art, such as the need for a lot of storage space when storing the device after use and the difficulty in adjusting the height of the device's seat.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a foot exercise device for preventing thrombosis, comprising a base, a first cavity inside the base, a motor fixedly connected to the inner wall of the first cavity, a transmission rod splinedly connected to the output end of the motor, a threaded rod fixedly connected to one end of the transmission rod, a connecting plate threadedly fitted onto the surface of the threaded rod, connecting rods fixedly connected to both sides of the connecting plate, one end of the connecting rod extending to the outside of the base, a connecting seat fixedly connected to one end of the connecting rod, a fixed seat fixedly connected to the top of the connecting seat, a lifting column movably inserted into the top of the fixed seat, a seat fixedly connected to the top of the lifting column, a second cavity inside the fixed seat, a sliding plate slidably connected to the inner wall of the second cavity, a locking block fixedly connected to one side of the sliding plate, a spring and a damper connected together between the sliding plate and the inner wall of the second cavity, and a locking groove adapted to the locking block on the surface of the lifting column.

[0011] Optionally, a mounting bracket is fixedly connected to the top of the base, and a damping wheel is rotatably connected to the inner wall of the mounting bracket. A foot pedal is fixedly connected to the center of the damping wheel. The damping wheel and the foot pedal are fixedly connected. When the damping wheel rotates around the inner wall of the mounting bracket, it will generate moderate resistance, simulating the leg exertion feeling when walking, making the foot movement more in line with the physiological laws of the human body. The foot pedal is directly used for users to place their feet. The pedaling action drives the damping wheel to rotate synchronously, driving the feet to complete repeated flexion, extension, rotation and other regular movements, thereby continuously squeezing the leg blood vessels and promoting blood return. It is the direct component that realizes the core function of "preventing thrombosis".

[0012] Optionally, a first limiting rod is movably passed through the surface of the sliding plate. One end of the first limiting rod is fixedly connected to the inner wall of the second cavity to restrict the movement direction of the sliding plate and prevent the sliding plate from shifting, tilting or shaking when sliding left and right.

[0013] Optionally, a second limiting rod is movably inserted into the other end of the connecting rod. One end of the second limiting rod is fixedly connected to the inner wall of the first cavity to restrict the movement trajectory of the connecting rod and prevent the connecting rod from tilting, deviating or shaking when it moves with the connecting plate.

[0014] Optionally, a push rod is fixedly connected to the surface of the sliding plate. One end of the push rod extends to the outside of the fixed base, and a fixed block is fixedly connected to the other end of the push rod. The fixed block provides a convenient gripping point for the user, allowing the user to complete the adjustment operation simply by pulling the external fixed block without directly contacting the internal structure of the device, greatly simplifying the steps of adjusting the seat height.

[0015] Optionally, the base is equipped with casters at the bottom, and the casters have brake pads inside. The casters are installed at the bottom of the base, allowing the device to move flexibly in any direction on the ground, making it convenient for users to adjust the position of the device according to the usage scenario.

[0016] (III) Beneficial Effects

[0017] This invention provides a foot exercise device for preventing thrombosis, which has the following beneficial effects:

[0018] 1. This foot exercise device for preventing thrombosis features an automated retraction structure driven by a motor during storage. It eliminates the need for manual handling or disassembly; simply activating the motor allows the seat to retract towards the base, significantly simplifying storage and saving storage space when the device is not in use. This solves the problem of traditional equipment storage consuming a lot of space and enhances the device's practicality in space-constrained settings such as homes and rehabilitation rooms.

[0019] 2. This thrombosis prevention foot exercise device, in the seat height adjustment stage, utilizes a combination of a fixing block, push rod, locking block, and spring. Users can quickly and securely adjust the seat height and lock it securely by simply pulling and releasing. This design can accurately adapt to users of different heights and body types, ensuring that they can use the device in a comfortable posture. It avoids the problem of improper posture caused by the fixed seat height of traditional devices, which not only ensures the effectiveness of foot exercise but also reduces the risk of discomfort in the waist and legs, thus improving the safety and comfort of use.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a foot exercise device for preventing thrombosis, including a base 1. The base 1 has a first cavity inside. A motor 2, model Y160M1-2, is fixedly connected to the inner wall of the first cavity. A transmission rod is splined to the output end of the motor 2. A threaded rod 3 is fixedly connected to one end of the transmission rod. A connecting plate 4 is threaded onto the surface of the threaded rod 3. The connecting plate 4 is threaded onto the threaded rod 3 and fixedly connected to connecting rods 5 on both sides, serving as a transmission intermediary to transmit the rotational force of the threaded rod 3 to the connecting rods 5, driving the upper structure to move synchronously. Connecting rods 5 are fixedly connected to both sides of the connecting plate 4. One end of the connecting rod 5 extends to the outside of the base 1. A connecting seat 6 is fixedly connected to the top of the connecting seat 6. A fixed seat 7 is fixedly connected to the top of the fixed seat 7. A lifting column 8 is movably inserted into the top of the fixed seat 7. A seat 9 is fixedly connected to the top of the lifting column 8. The seat 9 is a component for users to sit on. Its height can be adjusted by the lifting column 8 to accommodate users of different heights and body types, ensuring comfortable posture during use and avoiding the impact of improper posture on exercise performance or causing discomfort. A second cavity is opened inside the fixed seat 7. A sliding plate 10 is slidably connected to the inner wall of the second cavity. A locking block 11 is fixedly connected to one side of the sliding plate 10. A spring 12 and a damper 13 are connected between the sliding plate 10 and the inner wall of the second cavity. A slot adapted to the locking block 11 is opened on the surface of the lifting column 8.

[0027] A mounting bracket 18 is fixedly connected to the top of the base 1. A damping wheel 19 is rotatably connected to the inner wall of the mounting bracket 18. A foot pedal 20 is fixedly connected to the center of the damping wheel 19. The damping wheel 19 and the foot pedal 20 are fixedly connected. When the damping wheel 19 rotates around the inner wall of the mounting bracket 18, it will generate moderate resistance, simulating the leg force exertion during real walking, making the foot movement more in line with the physiological laws of the human body. The foot pedal 20 is directly used by the user to place both feet. The pedaling action drives the damping wheel 19 to rotate synchronously, driving the feet to complete repeated flexion, extension, rotation and other regular movements, thereby continuously squeezing the blood vessels in the legs and promoting blood return. It is the direct component that realizes the core function of "preventing thrombosis".

[0028] A first limiting rod 14 is movably passed through the surface of the sliding plate 10. One end of the first limiting rod 14 is fixedly connected to the inner wall of the second cavity to restrict the movement direction of the sliding plate 10 and prevent the sliding plate 10 from deviating, tilting or shaking when sliding left and right.

[0029] The other end of the connecting rod 5 is movably connected to a second limiting rod 15. One end of the second limiting rod 15 is fixedly connected to the inner wall of the first cavity to restrict the movement trajectory of the connecting rod 5 and prevent the connecting rod 5 from tilting, shifting or shaking when it moves with the connecting plate 4.

[0030] A push rod 16 is fixedly connected to the surface of the sliding plate 10. One end of the push rod 16 extends to the outside of the fixed base 7. A fixed block 17 is fixedly connected to one end of the push rod 16. The fixed block 17 provides a convenient gripping point for the user, so that the user does not need to directly contact the internal structure of the device. The adjustment operation can be completed by simply pulling the external fixed block 17, which greatly simplifies the steps of adjusting the height of the seat 9.

[0031] The bottom of the base 1 is equipped with casters 21, and the casters 21 have brake pads inside. The casters 21 are installed at the bottom of the base 1, which allows the device to move flexibly in any direction on the ground, making it convenient for users to adjust the position of the device according to the usage scenario.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: Start motor 2. When it is working, external electrical energy is input into motor 2, which causes the output end of motor 2 to rotate. The output end of motor 2 is tightly connected to the transmission rod through splines, which can stably transmit the rotational power to the transmission rod, thereby driving the threaded rod 3, which is fixed to the transmission rod, to rotate synchronously. The rotational motion of the threaded rod 3 is then converted into linear motion of the connecting plate 4 along the axial direction of the threaded rod 3 through thread transmission. Finally, it drives the connecting rod 5, the connecting seat 6 and the seat 9 to retract towards the base 1 as a whole, completing the storage action.

[0034] The second step: The push rod 16 is pushed by the fixed block 17 to drive the sliding plate 10 to slide in the second cavity of the fixed seat 7, and the spring 12 and damper 13 are compressed at the same time, so that the locking block 11 is disengaged from the slot on the surface of the lifting column 8. At this time, the lifting column 8 can move up and down freely to adjust the height of the seat 9. When the height is appropriate, the fixed block 17 is released, the elastic force of the spring 12 pushes the sliding plate 10 to reset, and the locking block 11 is re-engaged into the slot of the corresponding height, locking the lifting column 8, thereby completing the height adjustment of the seat 9.
