[0018] 2. The present invention adopts suspended closed-chain motion, which means that the distal end of the limb is fixed while the proximal end is active. The characteristic of closed-chain motion is that it requires coordinated motion of multiple joints. During activity training, closed-chain motion involves more muscles and joints, and requires the coordinated motion of multiple joints to complete, which is closer to real sports movements. In muscle strength rehabilitation training, closed-chain motion is a multi-joint coordinated motion that does not increase the shear force of the joints. It can stimulate the joint proprioceptors, produce limb movement and protective reflex arc activities, and can fully train the overall coordination of the joints and promote the recovery of the function of the joint proprioceptors, thereby promoting joint stability and functional rehabilitation. Closed-chain motion should be selected to restore function in the early stages of rehabilitation. The concept of the present invention is that the human body is trained in imbalance, more mobilizing the participation of stabilizing muscle groups, which is suitable for rehabilitation exercises for sub-healthy people.

[0019] 3. The steel cable adopts a fully enclosed structure to prevent human body from causing harm.

[0020] 4. The internal limit structure is adopted to overcome the disadvantage that the external limit of strength equipment can easily cause harm to the human body.

[0021] 5. The four-link structure is used to better imitate the human body's motion trajectory, reduce the shear force of the motion joints, and better protect the joints. It is also very comfortable to use.

[0022] 6. Traditional equipment does not display and evaluate exercise effects. This set of equipment adds a display to help people exercise scientifically and displays the fitness effects. It also comes with an intelligent player.

[0023] 7. The counterweight iron adopts a fully enclosed structure, and the iron latch is selected with a magnetic latch to ensure safety.

[0024] 8. The wireless sensor can measure the number of exercises, and the display part can show the number of exercises, exercise time, energy consumption, and exercise suggestions, etc.

[0025] 9. Under the demonstration and guidance of the intelligent system, perform prescription exercises accompanied by wonderful light music, allowing the human body to engage in scientific exercise with selflessness and full devotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 2: A suspended rowing machine, comprising a rear frame 1, a floor frame 2, a seat frame 3, an upper frame 4 and a front frame 5, wherein:

[0038] The top of the rear frame 1 is fixedly installed with an upper cover 11. Two symmetrical iron guide rods, a pull rod and a plurality of counterweight iron sheets are also installed inside the rear frame 1. The iron guide rods, the pull rods and the plurality of counterweight iron sheets cooperate to increase the amount of exercise of the athlete, which is the prior art. No further explanation is given here. The counterweight iron sheet is provided with a hole, and the counterweight iron sheet is detachably connected to the counterweight iron pin through the hole. The iron pin adopts a magnetic pin to ensure safety; the counterweight iron sheet is fixedly connected to the steel cable 61, and the steel cable 61 passes through the pulleys on the top, bottom and upper surface of the upper frame 4 and the ground frame 2 in turn, and is finally fixed to the bottom of the cushion frame 3. A front guard 12 is provided on one side of the rear frame 1. The setting of the front guard 12 and the upper cover 11 makes the rear frame form a closed structure to prevent human body from causing harm. A T-shaped ground frame 2 is installed on the bottom cross bar of the rear frame 1. The ground frame is hollow inside, so that the steel cable 61 can pass through the ground frame 2. The front end of the rear frame 1 is fixed to the front frame 5.

[0039] A rowing handle 51 is installed on the front frame 5 for the convenience of the athlete to hold it. The top center of the front frame 51 is connected to the upper frame 4 through a hanging frame.

[0040] The upper frame includes a frame 4 including a U-shaped bracket 41 and a cross beam 42. The U-shaped bracket 41 is fixedly connected to the cross beam 42. One end of the U-shaped bracket 41 is fixedly connected to the rear frame 1, and the other end is fixedly connected to the cross beam 42. The upper surface of the cross beam 42 is fixedly connected to the front frame 5. The first connecting rod 31 and the second connecting rod 32 are installed inside the cross beam 42. The second connecting rod 32 is installed on the upper frame 4 through a rotating shaft 321, an inner limit shaft 322, an inner limit buffer pad 323, a spacer sleeve 324, a bearing 325, and a cover 326. The bottom is connected to the seat cushion frame 3 through a small rotating shaft 329, a bearing 325, a large washer 327, and a hexagon socket pan head bolt 328. The first connecting rod 31 is arranged on a side of the second connecting rod 32 away from the seat cushion frame 3. The top of the first connecting rod 31 is movably connected to the crossbeam 42, and the bottom is fixedly connected to the seat cushion frame 3. A display 411 is installed on the U-shaped bracket 41. The display 411 is used to display the number of movements and play videos. The wireless sensor can record the number of movements according to the swing amplitude of the seat cushion frame 3, and convert the electrical signal into a wireless signal, and then transmit the wireless signal to the display 411. A device for receiving wireless signals is installed inside the display 411.

[0041] The seat frame is an L-shaped structure, with a back cushion 33 and a seat cushion 34 mounted on the seat frame 3. A pedal frame 36 is also mounted at the end of the seat frame 3. Foot covers 361 are fixed at both ends of the pedal frame 36. The foot covers 361 can increase the friction between the athlete and the pedal frame.

[0042] Principle of the invention: The athlete sits on the cushion 34, puts his feet on the foot cover 361, chooses the weight he can bear, inserts the iron pin into the counterweight iron sheet that is consistent with the weight, and the athlete holds the rowing handles 51 on both sides with both hands, straightens his back; pulls the body closer to the rowing handle end, and in the process of pulling the body, the cushion frame 3 moves forward. Since the steel cable 61 is fixed to the bottom of the cushion frame 3, the other end of the steel cable 61 is fixedly connected to the counterweight iron sheet, and the counterweight iron sheet will also move with the steel cable 61 during the pulling process, thereby achieving the purpose of fitness. Combining the four-bar linkage with the counterweight mechanism, the body weight and the external counterweight can be used as resistance to better imitate the human body's motion trajectory, reduce the shear force of the motion joints, and better protect the joints. And it feels particularly comfortable to use. A wireless inclination sensor is installed at the bottom of the seat cushion 34. When the wireless inclination sensor detects that the seat cushion 26 swings to a certain inclination angle (for example, +30°), the wireless receiving end of the display screen 411 receives the signal value, and its control chip performs signal conversion and data processing, and then uses the counting module to count once, and displays the number of times on the display screen 27, thereby realizing the recording and display process of the number of exercises; among them, the wireless inclination sensor adopts the WL926MB wireless transmission dual-axis digital inclination sensor.

[0043] Embodiment 3: The athlete sits on the cushion 34 and puts both feet on the foot covers 361; holds the rowing handles 51 on both sides with both hands, straightens the back; pulls the body closer to the rowing handles, so as to achieve the purpose of training the back muscles and arm muscles.
