DETAILED DESCRIPTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings.

[0017] As attached Figure 1 To Attachment Figure 6 As shown, Specific embodiment: A leg-pushing and chest-pressing linkage training equipment comprises a base plate 1, on which a foot pedal assembly 2, a chest press assembly 3, a seat 4 and a resistance unit 5 are arranged, a transmission assembly 6 is arranged between the foot pedal assembly 2, the chest press assembly 3 and the resistance unit 5, the foot pedal assembly 2 comprises two mounting seats 21 symmetrically arranged on the base plate 1, a first rotating shaft 22 is arranged between the mounting seats 21, a support rod 23 is fixed on the first rotating shaft 22, and a pedal 24 is fixed on the top of the support rod 23; the chest press assembly 3 comprises two fixing seats 31 symmetrically arranged between the pedal 24 and the seat 4, two rotatably connected push handles 32 are symmetrically arranged on the top of the two fixing seats 31; the resistance unit 5 comprises a base 51, on which a disc-shaped water tank 52 is arranged, a stirring paddle 53 is arranged in the water tank 52, the stirring paddle 53 is fixedly connected to the drive shaft 54, and pushing the push handle 32 and stepping on the pedal 24 can drive the drive shaft 54 ​​to rotate through the transmission assembly 6.

[0018] When exercising using the leg-pushing and chest-pushing linked training equipment of the present invention, the person exercising first sits on the seat 4, steps on the pedals 24 with both feet, holds the push handles 32 with both hands, pushes the push handles 32 to perform chest push exercises, and steps on the pedals 24 to perform leg-pushing exercises. When stepping on the pedals 24 and pushing the push handles 32, the transmission assembly 5 transmits the force to the drive shaft 54 ​​to drive the stirring paddle 53 to rotate. The stirring paddle 53 stirs the water in the water tank 52, and the water generates resistance to the rotation of the stirring paddle 53, which is fed back to the person exercising for training.

[0019] Since different people have different requirements for training intensity, the resistance unit 5 needs to be able to adjust the resistance to meet the needs of different people. The resistance generated by stirring the water in the water tank 52 by the stirring paddle 53 depends on the contact area between the stirring paddle 53 and the water. To this end, the structure of the stirring paddle 53 is designed as follows: The stirring paddle 53 includes a central axis 531 fixedly connected to the driving shaft 54, and a plurality of first blades 532 are fixedly arranged on the central axis 531 in a circular array, a second blade 533 is hingedly connected to the side of the first blade 532 away from the central axis 531, a first bearing 534 is fixedly arranged on the central axis 531 above the first blade 532, a rotating sleeve 535 is installed on the first bearing 534, a first cross bar 536 is provided on the side of the rotating sleeve 535, the first cross bar 536 is fixedly connected to the vertical bar 537, the vertical bar 537 is fixedly connected to the second cross bar 538, the second cross bar 538 is hinged to the slider 539, the slider 539 is slidably connected to the guide groove 540 on the second blade 533, and the rotating sleeve 535 is connected to the locking adjustment mechanism, through which the rotating sleeve 535 can be locked after adjusting the angle between the first cross bar 536 and the first blade 532.

[0020] When the rotating sleeve 535 is rotated, the first cross bar 536, the vertical bar 537 and the second cross bar 538 rotate with the rotating sleeve 535, and the second cross bar 538 pushes the slider 539 to slide along the guide groove 540, thereby adjusting the angle between the first paddle 532 and the second paddle 533, thereby changing the contact area between the entire paddle and the water in the water tank 52 when rotating, and changing the resistance of the stirring paddle 53 when rotating.

[0021] Preferably, the locking and adjusting mechanism includes a worm gear 541 fixedly connected to the top of the rotating sleeve 535, the worm gear 541 meshes with a worm 542, the worm 542 is rotatably connected in the volute 543, the volute 543 is fixed to the central shaft 531 by bolts 544, and an adjusting nut 545 is provided at one end of the worm 542 extending out of the volute 543. The worm 542 is driven to rotate by rotating the adjusting nut 545, and the worm 542 drives the worm gear 541 to rotate, and the worm gear 541 rotates synchronously with the rotating sleeve 535. The contact surface size between the blade and the water is adjusted by rotating the rotating sleeve 535. The worm gear structure has a self-locking ability, and the angle between the first blade 532 and the second blade 533 can be kept unchanged during the rotation of the stirring paddle 53. According to the needs, an opening is provided on the water tank 52, and a cover plate is provided on the opening. The adjusting nut 545 is placed in the opening, and the adjusting nut 545 can be operated by opening the cover plate.

[0022] Preferably, a plurality of through holes are provided on the first blade 532 or the second blade 533, and a plurality of one-way opening and closing plates 546 are elastically hinged on one side of the through hole. Pushing the push handle 32 and stepping on the pedal 24 drives the drive shaft 54 ​​to rotate, thereby driving the stirring paddle 53 to rotate. At this time, the one-way opening and closing plates 546 are located in front of the stirring paddle 53 in the rotation direction. At this time, due to the resistance of water, the one-way opening and closing plates 546 are in a closed state. When closed, the stirring paddle 53 has a large contact area with water, providing sufficient resistance. When resetting the push handle 32 and the pedal 24, due to the impact force of the reverse water, the one-way opening and closing plates 546 are opened to reduce the resistance of water, so that the push handle 32 and the pedal 24 can be reset more easily.

[0023] The transmission assembly 6 includes a first sprocket 61 and a second sprocket 62 arranged on the first rotating shaft 22, the first sprocket 61 is connected to the third sprocket 63 through a chain, the third sprocket 63 is connected to the input shaft of the gear transmission case 64, the output shaft of the gear transmission case 64 is fixedly connected to the first bevel gear 65, the first bevel gear 65 meshes with the second bevel gear 66, a coaxial fourth sprocket 67 is provided on the second bevel gear 66, the fourth sprocket 67 is connected to the fifth sprocket 68 through a chain, the fifth sprocket 68 is fixedly connected to the driving shaft 54, the second sprocket 62 is connected to the sixth sprocket 69 through a chain, the sixth sprocket 69 is connected to the seventh sprocket 70 through a chain, and the seventh sprocket 70 is fixedly connected to the push handle 32. When the pedal 24 is stepped on, the pedal 24 drives the support rod 23 and the first rotating shaft 22 to rotate synchronously. The rotation of the first rotating shaft 22 drives the input shaft of the gear box 64 to rotate through the sprocket transmission. The gear box 64 amplifies the effect of the pedal 24 through the gear transmission ratio, that is, the pedal 24 can drive the stirring paddle 53 to rotate many times by rotating a small angle, ensuring continuous resistance during exercise. In addition, the first rotating shaft 22 and the push handle 32 are also driven by a sprocket. When exercising, the exerciser can reasonably distribute the strength of the hands and legs to drive the stirring paddle 53 to rotate for training, or use the strength of the hands and legs alone to exercise, so as to meet the exercise needs under different conditions.

[0024] A lug plate 7 is fixed to one side of the support rod 23 near the water tank 52, the lug plate 7 is hinged to one end of the first connecting rod 8, the other end of the first connecting rod 8 is hinged to the lifting rod 9, a pressing block 10 is provided at the bottom of the lifting rod 9, the pressing block 10 is slidably connected to the guide sleeve 11, and a spring 12 is provided between the bottom of the guide sleeve 11 and the pressing block 10. When the pedal 24 is stepped on, the spring 12 is squeezed, and after the pedal 24 is released, the pedal 24 is reset under the action of the spring 12.

[0025] A column 13 is provided on the side of the support rod 23 away from the water tank 52, and a guide wheel 14 is provided on the column 13. A counterweight box 15 is provided on the side of the column 13 away from the support rod 23. A plurality of counterweights can be placed in the counterweight box 15. The counterweight box 15 is fixedly connected to the support rod 23 by a steel cable, and the steel cable is guided by the guide wheel 14. The counterweight box 15 is slidably connected to the vertical guide rod. Adding a counterweight can further adjust the magnitude of the resetting force when the pedal 24 is released. For example, when the contact area of ​​the stirring paddle 53 is large when it rotates, and the resetting resistance is large, the counterweight can be added to help faster resetting. In addition, adding a counterweight can also increase the resistance when stepping on the pedal, thereby helping training.

[0026] The seat 4 is provided with a front-rear adjustment mechanism and a height adjustment mechanism to meet the needs of people of different heights.
