Description

Technical Field

[0001] This utility model relates to the field of rowing machines, and in particular to a double-layer water bucket flow guiding and pressurizing rowing machine. Background Technology

[0002] Rowing machines, as a highly efficient aerobic fitness equipment, are favored by many fitness enthusiasts because they can simulate rowing movements and comprehensively exercise multiple muscle groups in the human body, including the legs, hips, back, shoulders, and arms. Currently, there are many types of rowing machines on the market. Based on the different ways of generating resistance, they can be mainly divided into air resistance rowing machines, magnetic resistance rowing machines, and water resistance rowing machines.

[0003] Existing water resistance rowing machines typically use a water tank to rotate a paddle in the water, utilizing water resistance to provide the resistance needed for exercise. The water resistance changes naturally with the rowing speed and force. However, most current water resistance rowing machines use a single water tank structure. When the paddle rotates in the water, the water flow is strongly disturbed, easily generating large impact forces and eddies, which in turn cause a splashing sound, creating noise that disturbs those around and affects the user's experience and comfort.

[0004] Therefore, it is necessary to design a double-walled water-guided pressurized rowing machine that can exercise by using water as resistance while circulating water through a double-walled water tank, reducing the sound of rushing water, lowering noise, and improving user comfort. Utility Model Content

[0005] To overcome the shortcomings of current water resistance rowing machines, which mostly use a single water tank structure, the water flow is strongly disturbed when the paddle rotates in the water, easily generating large impact forces and vortices, which in turn cause splashing water noise, disturbing those around and affecting the user's experience and comfort, this utility model provides a double-layer water tank guiding and pressurizing rowing machine that can use water as resistance for exercise while achieving water circulation through a double-layer water tank, reducing splashing water noise, lowering noise levels, and improving user comfort.

[0006] A double-layer water-bucket-guided pressurized rowing machine includes a base frame, a fixed outer shell, a support arm, a cross brace, foot pedals, a seat, rollers, hooks, handles, connecting belts, guide wheels, an inner tube, an outer tube, and a power unit.

The magnetic coupling adjustment switch and the processor are electrically connected through the control module. The inner side of the outer cylinder is connected to the inner cylinder. The left side of the inner cylinder has multiple holes. The magnetic coupling adjustment switch is used to adjust the size of the holes. A power component for applying resistance to exercise is provided between the base frame and the fixed shell.

[0007] Furthermore, all rollers are made of rubber.

[0008] Furthermore, the hook is curved.

[0009] Furthermore, it also includes a bracket, with the upper right part of the support arm connected to the bracket.

[0010] Furthermore, the power assembly includes a fixed plate, a rotating wheel, a transmission assembly, blades, a wheel shaft, a coil spring, and a centrifugal impeller. Two fixed plates are connected to the left side of the base frame. A rotating wheel is rotatably connected between the upper parts of the fixed plates. The tail end of the connecting belt wraps around the rotating wheel after passing over two guide wheels. A wheel shaft is rotatably connected between the lower parts of the fixed plates. The wheel shaft is rotatably connected to the inner cylinder and the fixed outer shell. Multiple turns of blades are connected to the middle of the wheel shaft. The blades are located inside the inner cylinder. A transmission assembly is provided between the wheel shaft and the rotating wheel. A coil spring is connected between the rotating wheel and the fixed plate on the right side. A centrifugal impeller is provided on the inner side of the right side of the outer cylinder.

The rollers 8, which are in contact with the base frame 1, are all made of rubber and have good wear resistance. The upper part of the cross support plate 5 is connected to the hook 9, and the hook 9 is connected to the handle 10. The hook 9 is arc-shaped to facilitate fitting the shape of the handle 10. The middle of the handle 10 is connected to the connecting strap 11. The support arm 3 is rotatably connected to the left and right guide wheels 12. The right inner side of the fixed shell 2 is connected to the outer cylinder 19. The left side of the outer cylinder 19 is equipped with a magnetic coupling adjustment switch. The magnetic coupling adjustment switch and the processor are electrically connected through the control module. The inner side of the outer cylinder 19 is connected to the inner cylinder 13. The left side of the inner cylinder 13 has multiple holes. The magnetic coupling adjustment switch is used to adjust the size of the holes. A power component for applying resistance to exercise is provided between the base frame 1 and the fixed shell 2.

[0024] like Figure 6 , Figure 7 and Figure 8 As shown, the power assembly includes a fixed plate 14, a rotating wheel 15, a transmission assembly 16, blades 17, a wheel axle 171, a coil spring 18, and a centrifugal impeller 20. Two fixed plates 14 are connected to the left side of the base frame 1. The rotating wheel 15 is rotatably connected between the upper parts of the fixed plates 14. The tail end of the connecting belt 11 wraps around the rotating wheel 15 after passing over two guide wheels 12. The wheel axle 171 is rotatably connected between the lower parts of the fixed plates 14. The wheel axle 171 is rotatably connected to the inner cylinder 13 and the fixed outer shell 2. The middle part of the wheel axle 171... Four rings of blades 17 are connected, and the blades 17 are located inside the inner cylinder 13. A transmission assembly 16 is provided between the wheel axle 171 and the rotating wheel 15. The transmission assembly 16 includes a pulley and a flat belt. The wheel axle 171 and the left side of the rotating wheel 15 are both connected to pulleys, and a flat belt is wound between the pulleys. A coil spring 18 is connected between the rotating wheel 15 and the right side of the fixed plate 14. A centrifugal impeller 20 is provided on the right inner side of the outer cylinder 19. The centrifugal impeller 20 is coaxially connected to the wheel axle 171 and communicates with the inner cylinder 13.

[0025] When using the double-walled water-guided pressure rowing machine for exercise, this device can be used. The user can place their phone or tablet on the support arm 3 for viewing. Then, the user sits on the seat 7, places their feet on the foot pedals 6 for positioning, and pulls the handle 10 to disengage from the hook 9 (which is curved). Pulling the handle 10 further moves the connecting belt 11, causing the guide wheel 12 to rotate. This causes the rotating wheel 15 to rotate along the fixed plate 14, driving the pulley to rotate, which in turn causes the flat belt to rotate. The coil spring 18 deforms, driving the wheel axle 171 to rotate, causing the blades 17 to rotate in the water and generate resistance for exercise. Simultaneously, the seat 7 moves, causing the rollers 8 to rotate and move. The resistance increases with the rowing speed. The rollers 8 are made of rubber. During exercise, the water flow generates centrifugal force as the blades 17 rotate, flowing through the left hole of the inner cylinder 13 to the outer cylinder 19. Simultaneously, the rotation of the blades 17 drives the centrifugal impeller 20 to rotate, which in turn draws water... Water between the outer cylinder 19 and the inner cylinder 13 is drawn back into the inner cylinder 13 to achieve circulation, reducing the splashing sound. At the same time, the size of the water flow hole from the inner cylinder 13 to the outer cylinder 19 is adjusted by the magnetic coupling adjustment switch, thereby adjusting the water flow resistance and adjusting the exercise intensity. Then, the handle 10 is pulled back to its original position, the coil spring 18 rotates back to its original position, the rotating wheel 15 rotates in the opposite direction to reset, driving the pulley to rotate in the opposite direction, causing the flat belt to rotate in the opposite direction, which in turn drives the wheel axle 171 and the blade 17 to rotate in the opposite direction to reset, causing the connecting belt 11 to reset. At the same time, the seat cushion 7 is moved to reset under human force. The above operation is repeated to pull the handle 10 and the connecting belt 11 and then pull them back to exercise. This allows for exercise using water as resistance while achieving water circulation through the double-layer water bucket, reducing splashing sound, lowering noise, and improving user comfort. After exercise, the handle 10 is engaged with the hook 9, the feet are disengaged from the foot pedal 6, and then the user stands up and disengages from the seat cushion 7. Finally, the mobile phone or tablet on the bracket 4 can be removed.
