[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Embodiment 1

[0033] Please refer to Figures 1 to 6 , which is an adjustable flat-bar resistance box as Embodiment 1 of the present utility model. The placement of the resistance box is preferably in the horizontal direction. Of course, it can also be used with a certain angle. The resistance box includes a liquid storage barrel 10 for storing liquid. A first liquid passing channel 11 is opened on the side wall of the liquid storage barrel 10 so that the liquid in the liquid storage barrel 10 flows out from the first liquid passing channel 11. A blocking member 20 is provided on the liquid storage barrel and is movably connected thereto for blocking the liquid in the liquid storage barrel 10 from flowing out. An inclined surface 21 or a stepped surface is provided above the blocking member 20. The position between the blocking member 20 and the liquid storage barrel 10 is adjusted so that the liquid level in the liquid storage barrel 10 is maintained at the required position; the inclined surface 21 or the stepped surface referred to in this embodiment is mainly used to limit the liquid level in the liquid storage barrel to be maintained at the required position, and tap water can be used as the liquid. The resistance box of the present utility model is provided with a blocking member 20 for blocking the liquid in the liquid storage barrel 10 from flowing out from the first liquid passing channel 11 of the liquid storage barrel 10. At the same time, an inclined surface 21 or a stepped surface is provided above the blocking member 20. By adjusting the blocking member 20, the liquid level in the liquid storage barrel 10 can be maintained at the required position, realizing the rapid adjustment of the liquid level in the liquid storage barrel, and thus adjusting the required resistance.

[0034] Specifically, please refer to Figure 3 , 4 , the blocking member 20 is arranged closely against the inner side wall of the liquid storage barrel 10 and is slidably connected to the liquid storage barrel 10. Specifically, in this embodiment, the blocking member 20 can be arranged inside the liquid storage barrel 10, and a sealing strip is arranged on one side of the blocking member 20 located inside the liquid storage barrel 10. The sealing strip is arranged close to the side wall of the blocking member 20 to achieve a sealing effect.

[0035] Specifically, please refer to Figure 3 , 4, the resistance box further includes a driving member 30 for driving the blocking member 20 to slide on the liquid storage barrel 10. Specifically, the driving member 30 can be arranged inside the liquid storage barrel 10; the driving member 30 includes a rotating shaft 31 rotatably connected to the liquid storage barrel 10 and a gear 32 arranged on the rotating shaft 31. A tooth portion 22 meshing with the gear 32 is arranged on the blocking member 20. The rotation of the rotating shaft 31 drives the rotation of the gear 32, and the cooperation between the gear 32 and the tooth portion 22 enables the blocking member 20 to slide on the liquid storage barrel 10. The cooperation between the gear 32 and the tooth portion 22 in this embodiment is similar to the cooperation between an existing gear 32 and a rack. By rotating the gear 32, the blocking member 20 is driven to slide on the inner side wall of the liquid storage barrel 10. Through the cooperation between the inclined surface 21 or the stepped surface and the first overnight channel, the adjustment of different liquid levels is realized. When the liquid level in the liquid storage barrel 10 is high, less liquid flows into the outer housing 50, and the resistance brought during the sliding process is small. On the contrary, the resistance is large.

[0036] For details, please refer to Figure 3 , 4 , the resistance box further includes a knob 40 for driving the driving member 30 to rotate. The lower part of the rotating shaft 31 is rotatably connected to the liquid storage barrel 10, and the knob 40 is fixedly arranged above it. An annular step 13 cooperating with the lower part of the rotating shaft 31 is also arranged on the liquid storage barrel 10, so as to limit the lower part of the rotating shaft 31 within the annular step 13, making the adjustment process more stable and smooth.

[0037] For details, please refer to Figure 4 , a slide rail 12 is arranged on the liquid storage barrel 10, and a slide groove 22 cooperating with the slide rail 12 is arranged at the bottom of the blocking member 20. The slide rail 12 is arranged along the inner side wall of the liquid storage barrel 10 and is arc-shaped, and the overall arc is consistent with the arc of the inner side wall of the liquid storage barrel 10, facilitating the sliding of the blocking member 20 along the inner side wall of the liquid storage barrel 10. Limit steps 121 are also arranged at both ends of the slide rail 12 to limit the sliding stroke of the blocking member 20.

[0038] The resistance box further includes an outer housing 50 and a stirring blade 60 arranged inside the outer housing 50 and outside the liquid storage barrel 10. The liquid storage barrel 10 is arranged inside the outer housing 50. A second liquid passing channel 521 is arranged between the liquid storage barrel 10 and the outer housing 50. The rotation of the stirring blade 60 drives the liquid in the outer housing 50 to enter the liquid storage barrel 10 along the second liquid passing channel 521. If the liquid level of the liquid storage barrel 10 can be maintained at a relative position after the blocking member 20 is adjusted, the water that enters the liquid storage barrel 10 through the second liquid passing channel 521 and is higher than the adjusted position will be discharged in time through the first liquid passing channel 11, so that during the sliding process, the required resistance is maintained.

[0039] For details, please refer to Figure 6, a diversion step 522 is provided at the top of the inner side wall of the outer casing 50 near the second overnight passage to make it easier for the liquid to enter the liquid storage barrel 10. A plurality of diversion steps 522 can be provided and arranged in sequence. Preferably, the diversion steps 522 all pass through the center point position of the liquid storage barrel 10 to achieve a better diversion effect.

[0040] The upper end of the rotating shaft 31 passes through the outer casing 50 and is connected to the knob 40. The resistance box further includes a rotating shaft 70 provided on the stirring blade 60. The bottom of the rotating shaft 70 is provided on the stirring blade 60 and passes through the liquid storage barrel 10 and the outer casing 50 in sequence above. The outer casing 50 includes a lower casing 51 and an upper casing 52 that cooperate with each other. A hollow cavity is formed inside the upper casing 52 and the lower casing 51. Another way to control the rotation of the driving member in this embodiment is that the resistance box further includes a driving mechanism for driving the driving member 30 to rotate. The driving structure uses an electric motor. The electric motor is directly fixedly provided on the outer casing 50, and the output end is fixedly connected to the upper part of the rotating shaft 31. The rotating shaft 31 is driven to rotate by the electric motor.

[0041] The liquid storage barrel 10 is locked to the top inside the outer casing 50 by a plurality of bolts. Specifically, a support step 523 for cooperating with the upper end opening of the liquid storage barrel 10 and a locking step 524 for bolt locking are provided inside the upper casing 52. Threaded holes are provided on the locking step 524. Locking ears are provided on the outside of the liquid storage barrel 10, and through holes for bolts to pass through are opened on the locking ears. The bolts pass through the through holes and are screwed to the locking step 524. The support step 523 is provided with a notch to form a second liquid passing channel 521. Since bolt locking requires sufficient height, the support step 523 and the locking step 524 are provided to facilitate firm bolt locking. The second liquid passing channel 521 is directly opened on the support step 523, which is convenient for the liquid driven by the rotation of the stirring blade 60 to better enter the liquid storage barrel 10. And the liquid that enters the liquid storage barrel 10 will flow back into the outer casing 50 through the first liquid passing channel 11 to ensure relative stability during the stirring process of the stirring blade 60 and meet the resistance required by the user. Of course, the second liquid passing channel 521 can be directly provided at the upper opening of the liquid storage barrel 10, and a specific groove is provided to form the second liquid passing channel 521. Embodiment 2

[0042] Please refer to Figures 1 to 6 , which is a rowing machine as Embodiment 2 of the present utility model, including a resistance box, and the structure of the resistance box adopts an adjustable flat barrel resistance box.

[0043] The adjustment principle of the resistance box of the present utility model is as follows:

[0044] First, place the rowing machine in place, inject enough liquid through the water injection hole of the upper shell 52, and then rotate the button to drive the blocking member 20 to keep the liquid level in the liquid storage barrel 10 at the desired position. During the rowing process, the liquid enters the liquid storage barrel 10 from the second liquid passage 521. The liquid entering the liquid storage barrel 10 causes the liquid level of the liquid storage barrel 10 to rise, but because the position of the blocking member 20 remains unchanged after being adjusted into place, the excess liquid will be discharged from the first liquid passage 11 in time. When different resistances need to be adjusted, the knob 40 can be rotated again to achieve quick adjustment.

[0045] To summarize, the resistance box of the utility model is used to block the liquid in the liquid storage barrel from flowing out of the first liquid passage of the liquid storage barrel by setting a blocking member, and at the same time, an inclined surface or a stepped surface is set above the blocking member. By adjusting the blocking member, the liquid level in the liquid storage barrel can be maintained at the desired position, thereby realizing rapid adjustment of the liquid level in the liquid storage barrel and further adjusting the desired resistance.

[0046] 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.
