It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Example 1

[0038] See also Figures 1 to 7 , is an adjustment structure of an inclined water resistance box as embodiment 1 of the utility model, comprising: a water tank 10, a water storage barrel 20, and an adjustment block 30, wherein the water tank 10 is arranged inclined; the water storage barrel 20 is arranged inclined on the inner side of the water tank 10, and a water inlet channel 201 is arranged between the upper part of the water storage barrel 20 and the inner top of the water tank 10, and a water outlet channel 202 is arranged on the side of the water storage barrel 20 near the bottom; the adjustment block 30 is arranged between the water storage barrel 20 and the inner side of the water tank 10, and is slidably connected to the water storage barrel 20, and the sliding adjustment block 30 is used to adjust the opening of the water outlet channel 202. The upper part in this embodiment is the high position when the water storage barrel 20 is in a tilted state. When the paddle 60 rotates, it can drive the liquid to move along the outer wall of the water storage barrel 20, and at the high point, part of the liquid can fall into the water storage barrel 20 through the water inlet channel 201, while the water outlet channel 202 is not located at the lowest position, but close to the side wall at the lowest position. The adjustment structure of the utility model adjusts the opening of the water outlet channel 202 by setting an adjustment block 30, so that the water level in the water storage barrel 20 is at different heights. When the paddle 60 in the rowing machine rotates, the water in the water tank 10 enters the water storage barrel 20 through the water inlet channel 201.

The inner side of the upper shell 12 is provided with a first step that matches the side wall, and the water storage barrel 20 is locked on the upper shell 12 by a plurality of bolts, and a plurality of internal threaded holes are provided along the circumferential direction of the first step, and the bolts pass through the bottom of the water storage barrel 20 and are screwed with the internal threaded holes.

[0042] Please refer to Figure 5-7The adjusting block 30 includes an arc-shaped main body 31, a first sliding groove 33 and a second sliding groove 34 arranged above and below the main body 31, a plurality of tooth grooves 32 are arranged on the inner side of the main body 31, a first sliding step 101 matched with the first sliding groove 33 is arranged at the top of the inner side of the water tank 10 (the first sliding step 101 is located at the inner top of the upper shell 12), and a second sliding step 203 matched with the second sliding groove 34 is arranged at the bottom of the inner side of the water storage barrel 20 (the second sliding step 203 is located on the bottom shell 21), and the adjusting block 30 is clamped by the arrangement of the upper shell 12 and the water storage barrel 20, so that the adjusting block 30 can be driven to slide by the driving member 40.

[0043] Please refer to Figure 2 The adjustment structure also includes a knob 70. The driving member 40 passes through the water tank 10 and is connected to the knob 70 outside the water tank 10. Rotating the knob 70 drives the driving member 40 to rotate, thereby driving the adjustment block 30 to slide along a preset track. The upper shell 12 is also provided with a water injection hole 121 connected to the chamber. The water injection hole 121 is also provided with a sealing plug 90. Liquid is easily injected through the water injection hole 121 and sealed by the sealing plug 90. The upper shell 12 is also provided with a mounting hole 122. A sealing block 80 is provided at the mounting hole 122 on the outer side of the upper shell 12. The sealing block 80 can be locked with the upper shell 12 by a number of screws, which not only has a certain sealing effect, but also can ensure that the knob 70 plays a certain supporting role during the rotation process. The knob 70 can be locked to the top of the driving member 40 by bolts. The bottom shell 21 of the water storage barrel 20 is provided with an annular step 211 for cooperating with the bottom of the rotating rod 41 to prevent the driving member 40 from deflecting during the rotation process. The sealing structure, reinforcing ribs, and bolt or screw locking methods involved in this embodiment are all conventional settings of those skilled in the art and will not be described in detail.

[0044] The working principle of the adjustment structure of the utility model is as follows:

[0045] Before use, first inject the required liquid through the water injection hole 121, then rotate the knob 70 to drive the adjusting block 30 to rotate, and the liquid in the water storage barrel 20 can enter the resistance space through the water outlet channel 202. During exercise, the paddle 60 rotates, and the liquid in the resistance space flows into the water storage space through the water inlet channel 201, and the liquid flowing into the water storage space flows back to the resistance space through the water outlet channel 202. When it is necessary to increase the resistance, rotate the adjusting block 30 to increase the opening of the water outlet channel 202, reduce the liquid height in the water storage barrel 20, and more liquid flows into the resistance space to increase the resistance during exercise. When it is necessary to reduce the resistance, rotate the adjusting block 30 to reduce the opening of the water outlet channel 202. After multiple rotations of the paddle 60, the liquid in the resistance space enters the water storage space through the water inlet channel 201. Since it has not reached a certain height, the liquid will not be discharged from the water outlet channel 202 to the resistance space at this time, and the required resistance can be gradually achieved.

[0046] Example 2

[0047] See also Figures 1 to 7 , is a rowing machine as embodiment 2 of the utility model, including an adjustment structure, which adopts the adjustment structure of an inclined water resistance box in embodiment 1.

[0048] In summary, the adjustment structure of the utility model adjusts the opening of the water outlet channel by setting an adjustment block so that the water level in the water storage barrel is at different heights. When the paddles in the rowing machine rotate, the water in the water tank enters the water storage barrel through the water inlet channel. When the water level reaches the adjusted height, the excess water will be discharged through the water outlet channel, thereby achieving the effect of adjusting the water resistance.

[0049] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
