Rowing machine is a machine used for training purposes to simulate water rowing. Currently, rowing machines mainly have three resistance modes: wind resistance, magnetic resistance and water resistance. Among them, water resistance rowing machine has the best simulation technology, which can make people feel the sight, sound and feeling of real rowing. When exercising, the resistance of liquid and the change of wheel speed are used in a short time to exercise the body's muscles, especially for strengthening the muscles of the legs, waist, upper limbs, chest and back.

During the stirring process of the paddle 50, the liquid in the resistance space enters the water storage space through the water inlet channel, and the water level in the water storage space is determined according to the height adjusted by the adjusting member 30. The excess liquid flows into the resistance space through the first drainage hole 201 to ensure that the required resistance is achieved during exercise.

The water storage barrel 20 is locked on the upper shell 12 by a plurality of bolts. A plurality of internal threaded holes are arranged along the circumferential direction of the first step 121. The bolts pass through the bottom of the water storage barrel 20 and are screwed with the internal threaded holes.

[0043] Please refer to Figure 2 The regulating structure also includes a rotating shaft 40 and a paddle 50 disposed at the lower end of the rotating shaft 40. The rotating shaft 40 passes through the water storage barrel 20 and is connected to the paddle 50. The paddle 50 includes a plurality of connecting rods 51, one end of which is connected to the lower end of the rotating shaft 40 and is perpendicular to the central axis of the rotating shaft 40, and a blade 52 disposed on the connecting rod 51 and away from the rotating shaft 40. The plurality of connecting rods 51 are located below the water storage barrel 20, and the plurality of blades 52 are located outside the water storage barrel 20. A shaft sleeve portion 23 sleeved on the outer wall of the rotating shaft 40 is disposed inside the water storage barrel 20. The rotating shaft 40 passes through the shaft sleeve portion 23 and is connected to the paddle 50. The water storage barrel 20 is made of plastic, and the bottom shell 21, the side portion 22 and the shaft sleeve portion 23 are integrally formed by injection molding.

[0044] Please refer to Figure 5 , 6, the lower side of the outer wall of the adjusting member 30 is cylindrical, and the bottom shell 21 is also provided with an annular step 211 matching the cylindrical shape; the adjusting member 30 is provided with a plurality of drainage steps 31 of different heights in sequence along the circumferential direction, and the corresponding drainage steps 31 are all provided with a second drainage hole 301 which can be connected with the first drainage hole 201, specifically, the heights of the plurality of drainage steps 31 are sequentially increased along the same direction, and a partition 34 is provided between two drainage steps 31, the adjusting member 30 comprises a bottom plate 32, a rotating shaft 33 provided on the bottom plate 32 and vertically connected to the bottom plate 32, and a plurality of second drainage holes 301 are arranged in a circumferential array on the bottom plate 32. The adjusting member 30 is rotated to make different second drainage holes 301 connect with the first drainage hole 201, and the corresponding drainage steps 31 keep the water level in the water storage barrel 20 at a desired height, and the partition 34 is provided on the bottom plate 32, and the two sides are respectively connected with the rotating shaft 33 and the drainage step 31.

[0045] Please refer to Figure 1 , 2 The adjustment structure also includes a knob 60 disposed on the outside of the water tank 10 and used to drive the adjustment member 30 to rotate. The rotating shaft 33 of the adjustment member 30 passes through the water tank 10 and is connected to the knob 60. The upper shell 12 is also provided with a mounting hole 124. A sealing block 70 is provided on the outer side of the upper shell 12 at the mounting hole 124. A locking step 331 is provided at the top of the rotating shaft 33. A locking groove matching the locking step 331 is provided on the knob 60, and a screw passes through the knob 60 and is screwed to the locking step 331. The upper shell 12 is also provided with a water injection hole 123 connected to the chamber. A sealing plug 80 is also provided on the water injection hole 123. Liquid is easily injected through the water injection hole 123 and is sealed by the sealing plug 80.

[0046] The working principle of the adjustment structure of the utility model is as follows:

[0047] Before use, first inject the required liquid through the water injection hole 123, then rotate the knob 60 to drive the adjusting member 30, and the liquid in the water storage barrel 20 flows into the resistance space through the first drainage hole 201. During exercise, the paddle 50 rotates, and the liquid in the resistance space flows into the water storage space through the water inlet channel, and the liquid flowing into the water storage space flows back to the resistance space through the first drainage hole 201. When it is necessary to increase the resistance, rotate the adjusting member 30 to lower the liquid height in the water storage barrel 20, and more water flows into the resistance space to increase the resistance during exercise. When it is necessary to reduce the resistance, rotate the adjusting member 30, and the second drainage hole 301 corresponding to the higher drainage step 31 is connected to the first drainage hole 201. After multiple rotations of the paddle 50, the liquid in the resistance space enters the water storage space through the water inlet channel. Since it has not reached a certain height, the liquid will not be discharged to the resistance space through the first drainage hole 201 at this time, and the required resistance can be gradually achieved.

[0050] In summary, the adjustment structure of the present invention adjusts the water level in the water tank to different heights by providing an adjustment member. When the paddles in the rowing machine rotate, the water in the water tank enters the water tank through the water inlet channel. When the water level reaches the adjusted height, the excess water will be discharged through the first drain hole, thereby achieving the effect of adjusting the water resistance.
