[0023] The utility model provides a pedal exerciser, combined with Figure 1-5 As shown, it includes a base 1, a rotating wheel 2, a pedal assembly 3, a transmission belt 8 and a flywheel assembly. The rotating wheel 2 and the flywheel assembly are both rotatably connected to the base 1. The pedal assembly 3 is connected to the axle of the rotating wheel 2 and drives the rotating wheel 2 to rotate. The rotating wheel 2 and the flywheel assembly are connected by the transmission belt 8. The flywheel assembly includes a first flywheel 4 and a second flywheel 5. The first flywheel 4 and the second flywheel 5 are respectively detachable and arranged on the left and right sides of the transmission belt 8 to enhance the intensity of unilateral or bilateral exercise. A first accommodating chamber 41 is provided in the first flywheel 4, and a second accommodating chamber 51 is provided in the second flywheel 5. The first accommodating chamber 41 and the second accommodating chamber 51 can be used to fill items such as water or sand to increase the weight and enrich the body sensation.

[0024] The pedal exerciser of the present invention provides a detachable first inertia wheel 4 and a detachable second inertia wheel 5 on the left and right sides of the transmission belt 8, so that the user can enhance the intensity of unilateral or bilateral exercise by increasing gravity according to their own needs, thereby meeting the different needs of customers. At the same time, the user can enrich the hand feeling or foot feeling by filling in objects such as water or sand.

[0025] like Figure 1 As shown, in this embodiment, when the user drives the pedal assembly 3 to rotate through the arms or legs, the pedal assembly 3 drives the rotating wheel 2 to rotate, and the rotating wheel 2 drives the first inertia wheel 4 and the second inertia wheel 5 to rotate through the transmission belt 8. At this time, the presence of the first inertia wheel 4 and the second inertia wheel 5 increases the strength required by the user, thereby enhancing the intensity of exercise.

[0026] like Figure 4 As shown, in this embodiment, such an arrangement can further change the weight of the first inertia wheel 4 and the second inertia wheel 5, thereby increasing the training intensity.

[0027] The first inertia wheel 4 is provided with a first opening connected to the first accommodating cavity 41 , and a first rotary cover 42 is detachably provided on the first opening. The second inertia wheel 5 is provided with a second opening connected to the second accommodating cavity 51 , and a second rotary cover 52 is detachably provided on the second opening.

[0028] like Figure 1 As shown, in this embodiment, this arrangement allows for the placement of objects such as metal, sand, and water in the first and second accommodating chambers 41 and 51 to increase weight. For example, water can be poured into the first and second accommodating chambers 41 and 51 during exercise, and then poured out when needed for carrying or transport, making the exercise more portable and simple in structure.

[0029] The inertia wheel assembly includes a transmission wheel 6 and a connecting rod 7. The transmission wheel 6 and the rotating wheel 2 are connected by the transmission belt 8. The connecting rod 7 passes through the transmission wheel 6 and rotates synchronously with the transmission wheel 6. The first inertia wheel 4 and the second inertia wheel 5 are respectively detachably connected to the left and right ends of the connecting rod 7.

[0030] like Figure 3 As shown, in this embodiment, the transmission wheel 6 is located in the middle of the connecting rod 7. The connecting rod 7 is a straight rod with a square cross-section. When the transmission belt 8 rotates the transmission wheel 6, the transmission wheel 6 drives the first and second inertia wheels 4 and 5 through the connecting rod 7. The first and second inertia wheels 4 and 5 are located on the left and right sides of the transmission wheel 6 to ensure balanced force on both sides. Users can also install inertia wheels on only the left or right side according to their needs to strengthen the strength of one arm or leg.

[0031] The inertia wheel assembly includes a first limiting member 71 and a second limiting member 72. The first limiting member 71 and the second limiting member 72 are detachably connected to the left and right ends of the connecting rod 7, respectively. The first limiting member 71 and the second limiting member 72 are respectively limited to the first inertia wheel 4 and the second inertia wheel 5.

[0032] like Figure 3 As shown, in this embodiment, when the connecting rod 7 rotates, the first limiting member 71 and the second limiting member 72 rotate synchronously. The first limiting member 71 and the second limiting member 72 are used to prevent the first and second inertia wheels 4 and 5 from separating from the connecting rod 7 during rotation.

[0033] The base 1 is provided with a mounting frame 11, and the left and right side walls of the mounting frame 11 are both provided with a first limiting opening 112 and a second limiting opening 113. The left and right ends of the rotating wheel 2 are both connected with a first locking member 21, and the first locking member 21 is coaxially arranged with the rotating wheel 2. The left and right ends of the transmission wheel 6 are both connected with a second locking member 61, and the second locking member 61 is coaxially arranged with the transmission wheel 6. The first limiting opening 112 is suitable for limiting the installation of the first locking member 21, and the second limiting opening 113 is suitable for limiting the installation of the second locking member 61.

[0034] like Figure 5 As shown, this arrangement facilitates installation and disassembly. The first inertia wheel 4 is confined between the first limiting member 71 and one second locking member 61, and the second inertia wheel 5 is confined between the second limiting member 72 and another second locking member 61. Both the first locking member 21 and the second locking member 61 are bearing lock nuts.

[0035] The base 1 is provided with a mounting frame 11, and a third accommodating cavity 111 is formed between the left and right walls of the mounting frame 11. The wheel 2 is accommodated in the third accommodating cavity 111 so that the axis of the wheel 2 is parallel to the horizontal plane.

[0036] like Figure 1 and 5 As shown, in this embodiment, the rotating wheel 2 is located between the left and right side walls of the mounting frame 11.

[0037] The pedal assembly 3 includes a connecting member 34 , a first pedal 31 and a second pedal 32 . The connecting member 34 is connected to the axle of the rotating wheel 2 . The first pedal 31 and the second pedal 32 are respectively arranged at the left and right ends of the connecting member 34 .

[0038] like Figure 1 As shown, in this embodiment, the distance between the first pedal 31 and the second pedal 32 is adapted to the width of the human shoulder, thereby being more ergonomic and making the user more comfortable during exercise.

[0039] The first pedal 31 and the second pedal 32 are both connected with a strap 33 , and the strap 33 is used to fix the arms or legs.

[0040] like Figure 1 As shown, in this embodiment, the user can fix his hands or feet on the first pedal 31 and the second pedal 32 through the straps 33 to prevent them from detaching during exercise, achieving a locking effect and being safer.

[0041] like Figure 1 As shown, in this embodiment, the pedal exerciser further includes a digital display 9, which is installed above the rotating wheel 2 to calculate the exercise time.
