[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6As shown, an exercise device includes a seat plate 11 fixedly mounted on a fitness frame 1, a detachable frame rod 12 mounted on the fitness frame 1, a detachable fixing sleeve 13 mounted on the frame rod 12, a rotating rod 2 rotatably mounted on the fixing sleeve 13, two sets of exercise components mounted on the rotating rod 2, and a drive component for driving the rotating rod 2 to rotate mounted on the fixing sleeve 13. Each exercise component includes a crank 3 and an L-shaped support plate 4. One end of the crank 3 is adjustablely mounted at the end of the rotating rod 2, and the L-shaped support plate 4 is rotatably mounted at the other end of the crank 3. A grip bar 41 is fixedly mounted on the L-shaped support plate 4. The two cranks 3 are located on the same side of the rotating rod 2 and are symmetrically positioned, or the two cranks 3 are located on opposite sides of the rotating rod 2.

[0024] When using the exercise equipment, the fitness frame 1, frame pole 12, and fixing sleeve 13 are assembled together, making the whole unit easy to assemble and disassemble. The overall height of the exercise equipment can be adjusted during assembly according to the user's height.

[0025] The rotating rod 2 has two working states: active rotation and passive rotation. When the drive assembly is activated, it causes the rotating rod 2 to rotate passively (the rotating rod 2 can rotate clockwise or counterclockwise as needed). Typically, the fitness frame 1 has a button electrically connected to the drive assembly. Pressing the start button activates the drive assembly, and pressing the stop button stops the drive assembly.

[0026] When using the exercise machine, the user sits on the seat 11. Because the L-shaped support plate 4 rotates relative to the crank 3, the user's two arms (upper arms and forearms) can rest on the two L-shaped support plates 4 respectively. The L-shaped support plates 4 support the user's upper arms and forearms, while allowing them to bend (to improve the exercise effect). The user can grasp the grip bar 41. Rotating the grip bar 41 causes the L-shaped support plate 4, crank 3, and rotating rod 2 to rotate. When the rotating rod 2 rotates actively, it mainly relies on the user's effort to achieve the rotation, resulting in a higher exercise intensity, suitable for people with good physical fitness. When the rotating rod 2 rotates passively, it mainly relies on the drive component to drive the rotation, allowing the user to exert less force, resulting in a lower exercise intensity, which enhances the exercise motivation of some people with poor physical fitness.

[0027] The exercise equipment has two usage modes, and different usage modes can exercise different parts of the body. Switching between different usage modes also prevents the exercise process from being monotonous and boring, thus increasing the fun.

[0028] In the first usage state of the exercise equipment, the two cranks 3 are located on the same side of the rotating rod 2 and are symmetrically positioned. The person sits on the seat 11, with their upper arms and forearms resting on the two L-shaped support plates 4 respectively. The person grasps the grip bar 41 and rotates it, causing the L-shaped support plates 4, cranks 3, and rotating rod 2 to rotate simultaneously. The two cranks 3 rotate forward or backward simultaneously, and the person's two arms rotate forward or backward simultaneously, similar to the forelimb running movements of animals like tigers and leopards. This effectively exercises the shoulders. The rotating rod 2 can be configured to rotate actively or passively, depending on the needs.

[0029] In the second usage state of the exercise equipment, the two cranks 3 are located on both sides of the rotating rod 2 and are in opposite positions. The person sits on the seat plate 11, with their two arms (upper arm and forearm) resting on the two L-shaped support plates 4 respectively. The person grasps the grip bar 41 and rotates the grip bar 41, causing the L-shaped support plates 4, cranks 3, and rotating rod 2 to rotate. The two cranks 3 can rotate alternately, one in front of the other, and the person's two arms rotate alternately, one in front of the other, similar to the forelimb walking movements of animals such as tigers and leopards. At this time, the person's shoulders, neck, and waist are effectively exercised. The rotating rod 2 can be set to rotate actively or passively as needed.

[0030] In this embodiment, the exercise device features an L-shaped support plate 4 that supports the upper arm and forearm, allowing them to bend and improving the exercise effect. The rotating rod 2 can rotate actively or passively, making it suitable for people with different physical abilities. When the two cranks 3 are located on the same side of the rotating rod 2 and are symmetrically positioned, the shoulders can be effectively exercised. When the two cranks 3 are located on opposite sides of the rotating rod 2, the shoulders, neck, and waist can be effectively exercised, thus exercising different parts of the body. The device is also easy to assemble, and its overall height is adjustable, further expanding its applicability to a wider range of people.

[0031] In one possible implementation, each of the rotating rods 2 has a fixing block 21 at its end, and each of the cranks 3 has a fixing plate 31 at its end. The fixing block 21 and the fixing plate 31 are square or circular and have the same size. A spring 5 is movably disposed between the fixing block 21 and the fixing plate 31. Two fixing grooves 211 are symmetrically arranged on the fixing block 21, one in front of the other. Two locking blocks 311 are symmetrically arranged on the fixing plate 31, and the two locking blocks 311 respectively engage with the two fixing grooves 211. The size of the fixing groove 211 is larger than the size of the locking block 311, so that the locking block 311 can engage with the fixing groove 211.

[0032] When the two cranks 3 are located on the same side of the rotating rod 2 and are symmetrically positioned, the two locking blocks 311 on the fixing plate 31 are locked in the two fixing grooves 211 on the fixing block 21, the spring 5 is in a contracted state, and under the action of the elastic force of the spring 5, the fixing block 21 and the fixing plate 31 are tightly fitted together.

[0033] When the two cranks 3 are positioned opposite each other on both sides of the rotating rod 2, a person pulls a fixed plate 31 away from the fixed block 21 (the person can adjust the left or right crank 3 as needed). The spring 5 is in the extended state, and the person can remove the spring 5. Then, the person rotates a fixed plate 31 180° so that the two cranks 3 are positioned opposite each other on both sides of the rotating rod 2. Then, the spring 5 is reinstalled, and the two locking blocks 311 on the fixed plate 31 are re-locked into the two fixing slots 211 on the fixed block 21. The spring 5 is in the contracted state, and under the elastic force of the spring 5, the fixed block 21 and the fixed plate 31 are tightly fitted together again.

[0034] In one possible implementation, each of the four corners of the fixing block 21 is provided with a connecting groove 212. One end of the spring 5 is fixedly connected to the connecting groove 212, and the other end of the spring 5 is fixedly provided with a hook 51. Each fixing plate 31 is provided with a hanging ring 312 at a position corresponding to the connecting groove 212, and each hook 51 is engaged with the hanging ring 312. The hook 51 and the hanging ring 312 cooperate to make the spring 5 detachable.

[0035] In one possible implementation, a fixing shaft 213 is provided at the center of each fixing block 21, and a blind hole is provided at the position corresponding to the fixing shaft 213 in each fixing plate 31, with the end of the fixing shaft 213 passing through the blind hole. The fixing shaft 213 supports the fixing plate 31. The two fixing grooves 211 and the fixing shaft 213 are on the same straight line.

[0036] As one possible implementation, a handle is fixedly provided on the end face of each fixing plate 31 away from the fixing block 21. The handle facilitates adjustment of the fixing plate 31 by a person.

[0037] As one possible implementation, each L-shaped support plate 4 has a side plate fixedly installed on the side away from the fixed plate 31. When a person exercises, the side plate can also support the upper arm and forearm, further enabling the upper arm and forearm to be effectively exercised.

[0038] In one possible implementation, the drive assembly includes a motor 7 and a transmission rod 6. The motor 7 is fixedly mounted on the outside of the fixed sleeve 13. The output shaft of the motor 7 is fixedly connected to the transmission rod 6 and can drive it to rotate. A main bevel gear 61 is fixedly mounted on the transmission rod 6.
