Specific implementation mode

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a self - generating aerobic training apparatus with hand - foot linkage, including an apparatus body 1, on which a transmission box 2, a transmission shaft 3 that penetrates the transmission box 2 and is rotatably arranged, and a vertical beam 4 near the front end are provided. An electronic display screen is arranged on the top of the vertical beam 4, and a seat cushion 110 is arranged on the top of the transmission box 2. The seat cushion 110 is the part where the training personnel sit.

[0023] A horizontal shaft 5 is penetratingly arranged on the vertical beam 4. Both ends of the horizontal shaft 5 are rotatably connected with connecting arms 6. The connecting arms 6 can swing back and forth. A handle 7 is arranged at the top of the connecting arm 6 and a connecting rod 8 is rotatably connected to its bottom. The handle 7 is the part held by the trainer. Both ends of the transmission shaft 3 are fixedly connected with connecting handles 9. The two connecting handles 9 and the transmission shaft 3 form a Z shape. One end of the connecting rod 8 is fixedly connected with a transfer sleeve 101 that is rotatably connected to one side of the adjacent connecting handle 9. Specifically in implementation, a limiting shaft sleeved in the transfer sleeve 101 can be welded to the top of one side of the connecting handle 9. When holding the handles 7 on both sides of the vertical beam 4 with both hands and then swinging back and forth alternately, it will drive the connecting handle 9 to swing back and forth.

[0024] A support plate 102 is fixedly connected to the outer wall of the transfer sleeve 101. A pedal 103 located above the transfer sleeve 101 is arranged at the free end of the support plate 102. Specifically in implementation, an installation hole can be opened on one side of the support plate 102, a rotating shaft is arranged on the pedal 103, and one end of the rotating shaft is fixedly connected to the installation hole. The pedal 103 is the part stepped on by the trainer. When the trainer cyclically steps on the pedal 103, it will drive the transmission shaft 3 to continuously rotate, and then can drive the connecting arm 6 to swing back and forth, realizing the combined aerobic training of hands and feet.

[0025] Furthermore, a generator 104 and a storage battery 105 are arranged in the transmission box 2. The input shaft of the generator 104 is connected to the transmission shaft 3 through a transmission group 106. When the transmission shaft 3 rotates, the generator 104 will rotate to generate electricity. The electricity generated by the generator 104 is transmitted to the storage battery 105 through wires for storage. The storage battery 105 supplies power to the electronic display screen through wires.

[0026] Specifically, the belt transmission group 106 includes a pulley one 1061, a transmission belt 1062, and a pulley two 1063. The pulley one 1061 is fixedly sleeved on the transmission shaft 3. The pulley two 1063 is fixedly sleeved on the input shaft of the generator 104. One end of the generator 104 is fixedly connected to one side inside the transmission box 2. The pulley one 1061 is connected to the pulley two 1063 through the transmission belt 1062. Thus, when the transmission shaft 3 rotates, it can drive the generator 104 to rotate through the pulley one 1061, the transmission belt 1062, and the pulley two 1063. Among them, the pulley one 1061 can be a pulley with an internal ratchet structure to reduce the load of the reverse rotation of the transmission shaft 3 and facilitate the trainer to train with low intensity.

[0027] In this embodiment, a positioning sleeve 61 rotatably connected to the horizontal shaft 5 is welded to one side of the connecting arm 6. A seat sleeve 107 is fixedly sleeved on one side of the connecting arm 6 and is located above the positioning sleeve 61. A secondary arm 108 is rotatably connected to one side of the seat sleeve 107. Preferably, during specific implementation, a support shaft 1071 is welded to one side of the seat sleeve 107, and a connecting sleeve 1081 sleeved outside the support shaft 1071 is welded to the bottom of the secondary arm 108. An adjustment and locking member 109 is provided between the seat sleeve 107 and the secondary arm 108. The secondary arm 108 is also a handheld component and can swing back and forth. The function of the adjustment and locking member 109 is to lock the swung secondary arm 108. When the secondary arm 108 swings back and forth, the distance between it and the user's body can be changed, making it suitable for people with different arm lengths to use.

[0028] Specifically, the adjustment and locking member 109 includes a plug pin 1091 and a spring 1092. A groove 10711 is formed on the outer peripheral wall of the support shaft 1071. A positioning plate 1072 located on one side of the connecting sleeve 1081 is welded to one side of the seat sleeve 107. The plug pin 1091 is elastically slidably connected to the positioning plate 1072 through the spring 1092. During specific implementation, a sliding hole can be formed on the positioning plate 1072, and the plug pin 1091 passes through the sliding hole. Then, a retaining ring is welded to the plug pin 1091, and the retaining ring is located between the positioning plate 1072 and the support shaft 1071. The spring 1092 is sleeved on the plug pin 1091 and is located between the retaining ring and the positioning plate 1072. Thus, the spring 1092 applies an elastic thrust to the plug pin 1091 in the direction of the support shaft 1071. One end of the plug pin 1091 faces the groove 10711. A plurality of through holes 10811 are formed on the outer peripheral wall of the connecting sleeve 1081 in a circumferentially uniform distribution and are used in cooperation with the plug pin 1091. When one end of the plug pin 1091 passes through the through hole 10811 and is inserted into the groove 10711, the connecting sleeve 1081 can be limited. When the plug pin 1091 leaves the through hole 10811, the entire secondary arm 108 can be easily rotated.

[0029] In this embodiment, the secondary arm 108 is composed of a lower rod 10801 and an upper sleeve 10802. The upper sleeve 10802 is sleeved on the lower rod 10801 and is in a sliding connection. That is to say, the length of the secondary arm 108 can be adjusted. A locking bolt 108021 is screwed through the outer peripheral wall of the upper sleeve 10802. One end of the locking bolt 108021 cooperates with one side of the lower rod 10801. After the length of the secondary arm 108 is adjusted, when the locking bolt 108021 is tightened, the lower rod 10801 and the upper sleeve 10802 can be locked.

[0030] In this embodiment, stepping rods 41 are welded to both sides of the vertical beam 4 near the bottom. The stepping rods 41 are of a fixed structure, which is convenient for training personnel to place their feet on the stepping rods 41 when training their arms alone.

[0031] Working principle: When in use, the trainer sits on the seat cushion 110, then steps on the pedal 103 with the feet, then holds the handle 7 or the auxiliary arm 108 as needed with the hands, and then the hands and feet exert force simultaneously to drive the transmission shaft 3 to rotate forward. At this time, the arms swing back and forth alternately, and the feet perform cyclic pedaling movements, realizing the combined aerobic training of the hands and feet. At the same time, the transmission shaft 3 drives the generator 104 to generate electricity through the transmission group 106, and the electricity is stored in the storage battery 105, realizing the self-power generation function.

[0032] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only includes an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
