Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment, and more specifically, to a rehabilitation bicycle. Background Technology

[0002] Elderly individuals experiencing muscle atrophy, osteoporosis, or decreased balance can improve blood circulation, increase bone density, and prevent falls through cycling. Patients confined to beds for extended periods also suffer from muscle atrophy and reduced bodily function due to lack of exercise; low-intensity cycling can alleviate muscle stiffness and gradually restore bodily functions. Current rehabilitation bicycles can meet the cycling needs of these groups. However, in addition to lower limb rehabilitation, these individuals often require upper limb rehabilitation as well, and their upper limbs are used more in daily life, thus necessitating more extensive rehabilitation training. Existing rehabilitation bicycles often only provide lower limb rehabilitation, or while they may offer upper limb rehabilitation, their functionality is limited, requiring patients to use multiple rehabilitation devices for different training sessions. Utility Model Content

[0003] The present invention aims to overcome the defects of the prior art and provide a rehabilitation bicycle to solve the problem of the limited functionality of existing rehabilitation bicycles.

[0004] The technical solution adopted by this utility model is a rehabilitation bicycle, including a base frame.

The two ends of the support crossbar are provided with a rotating machine, the middle is provided with a rotating machine, and the bottom is provided with a stretching machine.

[0005] The stationary bike allows users to perform regular leg exercises, strengthening the muscles of the thighs and calves, enhancing muscle contraction and endurance, improving muscle coordination, and also improving cardiovascular endurance and work efficiency, increasing oxygen supply, promoting blood circulation, and restoring overall bodily function. The circular and rotary machines allow users to perform various arm exercises to strengthen arm muscles. The stretching machine provides lateral stretching exercises, aiding in the recovery of upper body function. By integrating the stationary bike, circular bike, and rotary machine onto the same equipment, users can perform different rehabilitation training according to their needs without needing to change equipment.

[0006] Furthermore, the rotating ring machine includes a rotating drum and a rotating handle. The rotating drum is set at both ends of the support crossbar, and the rotating handle is rotatably connected to the rotating drum.

[0007] The rotating ring machine is set at both ends of the support crossbar. Users can perform horizontal rotation training of the arm by rotating the handle. Horizontal rotation training usually involves the muscles of the shoulder joint and upper arm, which helps to enhance the strength and flexibility of these parts. It plays a very important role in helping patients restore the ability of the arm to move in the horizontal plane and improve the overall function of the shoulder joint and upper limb.

[0008] Furthermore, the rotating machine includes a rotating block and a rocker arm. The rotating block is positioned above the crossbar of the support, and the rocker arm is positioned on both sides of the rotating block and is rotatably connected to the rotating block.

[0009] The rotating block is located above the crossbar of the support, and the crank is rotatably connected to the rotating block. Users can rotate the crank to perform vertical rotation movements of the arm. Vertical rotation training mainly targets the muscle groups of the forearm, which helps to improve the strength and coordination of these muscles. It is crucial for restoring the rotation ability of the forearm and can help patients restore basic daily activities such as wringing towels and opening doors.

[0010] Furthermore, the stretching machine includes a pull ring, a connecting rope, and multiple rotating wheels, which are respectively arranged on the longitudinal rod of the support and below the crossbars on both sides of the longitudinal rod. The rotating wheels are provided with grooves, and the connecting rope is arranged in the grooves. The two ends of the connecting rope pass through the rotating wheels below the crossbars of the support and are connected to the pull ring. The middle part of the connecting rope is arranged in the groove of the rotating wheel on the longitudinal rod of the support.

[0011] Users can perform left and right stretching movements using the stretching machine. Left and right stretching is a comprehensive stretching exercise that can effectively stretch and strengthen multiple muscle groups in the arms, shoulders, and back, playing an important role in improving upper limb flexibility and preventing muscle tension.

[0012] Furthermore, the bicycle mechanism includes a pedal damper and pedals, the pedals being a left pedal and a right pedal, respectively disposed on both sides of the pedal damper and rotatably connected to the pedal damper.

[0013] The user can perform leg rehabilitation training by stepping on the left and right pedals with their left and right feet respectively, which can strengthen the muscles of the thighs and calves, enhance muscle contraction and endurance, improve muscle coordination, improve cardiopulmonary endurance and work efficiency, increase oxygen supply, promote blood circulation, and restore the body's overall function.

[0014] Furthermore, a hinge seat is provided at the front of the base frame, and the lower end of the support longitudinal rod is hinged to the hinge seat. The hinge seat is provided with a plurality of first positioning holes arranged in an arc with the hinge point as the center.

The first positioning hole and the first fixing hole are connected by a pin.

[0015] The first connecting hole on the hinge seat is hinged to the second connecting hole on the longitudinal rod of the support, allowing the longitudinal rod to rotate around the hinge. Different first positioning holes on the hinge seat are connected to the first fixing holes on the longitudinal rod of the support, allowing adjustment of the tilt angle of the longitudinal rod.

[0016] Furthermore, the support column includes a first column and a second column. The lower end of the second column is inserted into the upper end of the first column. The upper end of the first column is provided with a second fixing hole. The lower end of the second column is provided with a plurality of second positioning holes along the length direction of the second column. The second positioning holes and the second fixing holes are fixed together by a first positioning bolt.

[0017] The support column is a telescopic structure. Different second positioning holes on the second column are connected to the second fixing holes at the upper end of the first column, which can adjust the depth of the second column inserted into the first column, thereby adjusting the height of the support crossbar.

[0018] Furthermore, the seat assembly includes a seat bracket and a seat. A sleeve is provided above the seat bracket, and the sleeve is provided with multiple third positioning holes. A guide sleeve is provided below the seat, and the guide sleeve is provided with a third fixing hole. The third positioning holes and the third fixing holes are fixed together by a second positioning bolt.

[0019] The sleeve is tilted, with its rear end higher than its front end. Different third positioning holes on the sleeve connect to the third fixing holes on the guide sleeve, allowing adjustment not only of the horizontal distance between the seat and the bicycle machine but also of the seat height. Users can adjust the seat according to their height and body type for greater comfort.

[0020] Furthermore, it also includes a cardiac oxygenation measuring device, which has a display screen positioned above the crossbar of the support frame.

[0021] During exercise, a user's heart rate and blood oxygen levels will increase with the duration and speed of exercise, but the user is unaware of this. When these levels reach a certain point, the user may experience dizziness or other symptoms, potentially causing them to fall off the equipment and sustain injury. Therefore, monitoring the user's heart rate and blood oxygen levels is necessary. A cardiac oxygenation device is installed on the rehabilitation bicycle to monitor the user's heart rate and blood oxygen levels. The display screen of the cardiac oxygenation device is positioned above the crossbar of the support frame, allowing the user to easily monitor their heart rate and blood oxygen levels at any time during exercise.

[0022] Furthermore, an oxygen supply component is provided below the seat assembly, and the oxygen supply component has an air outlet with a valve at the air outlet.

[0023] During rehabilitation training, especially for patients with cardiopulmonary insufficiency, oxygen supply devices can ensure that they do not experience discomfort or other dangerous situations due to insufficient oxygen during exercise. Users can decide whether to use the oxygen supply device according to their own needs. When needed, simply connect the oxygen delivery tube to the outlet and open the valve.

[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: By integrating a bicycle machine, a rotatory machine, a rotating machine, and a stretching machine onto the same equipment, users can perform leg exercises on the bicycle machine, strengthening the muscle groups of the thighs and calves and improving leg muscle coordination. The rotatory machine allows for horizontal arm rotation, enhancing the strength and flexibility of the upper arm and shoulder joints, and improving the overall function of the shoulder joint and upper limbs. The rotating machine allows for vertical arm rotation, improving forearm strength and coordination, and helping patients regain basic daily activities such as wringing towels and opening doors. The stretching machine allows for lateral stretching, effectively stretching and strengthening multiple muscle groups in the arms, shoulders, and back, playing a vital role in restoring upper limb function. Users can perform different rehabilitation training on the same equipment without frequently changing equipment. The tilt angle and height of the bicycle frame's longitudinal bar, as well as the fore-and-aft position and height of the seat, are adjustable, allowing users to find a suitable angle and height. A cardiac oxygenation device monitors the user's heart rate and blood oxygen levels, and its display screen is located above the crossbar of the frame for easy monitoring during exercise.
