[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.
[0021] The utility model provides a water-resistant rowing machine water tank waterproof sealing structure, such as Figure 1 and Figure 2 As shown, it includes a water tank, a rotating shaft 1, a resistance mechanism, a fixing mechanism, a driving mechanism, a connecting piece and a sealing piece; an axial hole 9 is opened on the water tank, and the rotating shaft 1 is inserted into the axial hole 9, one end of the rotating shaft 1 is fixedly connected to the resistance mechanism inside the water tank, and the other end of the rotating shaft 1 is rotatably connected to the bearing 8 of the fixing mechanism outside the water tank, and is driven to rotate by the driving mechanism, the connecting piece is fixedly arranged on the outside of the water tank around the axial hole 9 by the fixing mechanism, and is used to connect the frame of the rowing machine, the sealing piece is arranged on the rotating shaft 1 inside the fixing mechanism, and is located between the bearing 8 and the axial hole 9; when the driving mechanism drives the resistance mechanism to rotate through the rotating shaft 1, the sealing piece is used to seal the axial hole 9, so that a sealed space is formed inside the water tank.
[0022] The utility model mainly arranges a seal on the rotating shaft 1 inside the fixing mechanism. Since the rotating shaft 1 is rotatably connected with the bearing 8, there will be a certain gap between the rotating shaft 1 and the bearing 8. Therefore, the seal is arranged between the bearing 8 and the shaft hole 9 of the upper housing 2 of the water tank. When the driving mechanism (not shown in the figure) drives the resistance mechanism to rotate through the rotating shaft 1, the seal can seal the space between the bearing 8 and the shaft hole 9, thereby preventing the water inside the water tank from seeping out from the gap between the rotating shaft 1 and the bearing 8 through the shaft hole 9, effectively improving the sealing performance of the water tank, and the design is humanized.
[0023] Further, the resistance mechanism is an impeller (not shown in the figure), the impeller is placed inside the water tank, and one end of the rotating shaft 1 is fixedly arranged at the center of the impeller. The resistance mechanism of this embodiment adopts an impeller, and the impeller cooperates with the rotating shaft 1, one end of the rotating shaft 1 is fixedly connected to the center of the impeller, and the other end of the rotating shaft 1 passes through the shaft hole 9 on the water tank and is rotatably connected to the fixing mechanism outside the water tank. Since the impeller is placed inside the water tank, when the rotating shaft 1 drives the impeller to rotate, the water inside the water tank provides resistance to the impeller, so that when the user uses the driving mechanism to pull the rotating shaft 1 to rotate, the exercise effect is achieved. In addition, the resistance size of the resistance mechanism can also be adjusted by the following methods. One is to adjust the angle of the impeller blades. By adjusting the angle of the blades, the force required for rowing can be changed. Generally speaking, reducing the angle of the blades can reduce the resistance, while increasing the angle of the blades can increase the resistance. Another method is to change the water level of the water tank. By adjusting the water level in the water tank, the force required for rowing can also be changed. Generally speaking, the higher the water level in the water tank, the greater the resistance generated by the resistance mechanism.
[0024] like Figure 1 and Figure 2As shown, the fixing mechanism also includes a shaft fixing seat 5, a through hole for bearing 8 is formed on the shaft fixing seat 5, and the bearing 8 is fixedly arranged in the through hole for bearing 8; the other end of the rotating shaft 1 passes through the through hole for bearing 8, and is rotatably connected to the shaft fixing seat 5 in cooperation with the bearing 8, and the shaft fixing seat 5 abuts against the outer surface of the box body around the shaft hole 9. In this embodiment, the rotating shaft 1 is fixed by the shaft fixing seat 5, a through hole for bearing 8 is formed on the shaft fixing seat 5, and the bearing 8 is fixedly arranged in the through hole for bearing 8, and the other end of the rotating shaft 1 located on the outer surface of the upper box body 2 of the water tank is rotatably connected to the shaft fixing seat 5 through the bearing 8, so as to ensure the stability of the rotating shaft 1 when the driving mechanism drives it to rotate, and improve the user experience.
[0025] like Figure 1 and Figure 2 As shown, it also includes bolts 6. The outer surface of the water tank is concave around the shaft hole 9 to form an annular groove. A plurality of nut seats 10 are provided in the annular groove. The shaft fixing seat 5 is provided with a plurality of through holes matching the nut seats 10.

The bolts 6 of this embodiment are M6 bolts. The outer surface of the water tank is concave around the shaft hole 9 to form an annular groove. A plurality of nut seats 10 are provided in the annular groove. The shaft fixing seat 5 is locked and fixed by the bolts 6 passing through the through holes of the shaft fixing seat 5 and cooperating with the nut seats 10. This design effectively utilizes the space of the upper housing 2 of the water tank, improves the aesthetics of the water tank, and directly arranging the nut seats 10 in the annular groove is also conducive to the installation of the shaft fixing seat 5.
[0026] like Figure 1 and Figure 2 As shown, the sealing member is a skeleton oil seal 7, which is sleeved on the rotating shaft 1 in the shaft fixing seat 5 and is located between the bearing 8 and the shaft hole 9. In this embodiment, by arranging the skeleton oil seal 7 on the rotating shaft 1 in the shaft fixing seat 5, and the skeleton oil seal 7 is located below the bearing 8, on the one hand, the bearing 8 can be kept in a lubricated state, wear and friction can be reduced, and the service life can be extended; on the other hand, the space between the bearing 8 and the shaft hole 9 can be sealed to prevent the water inside the water tank from seeping out from the gap between the rotating shaft 1 and the bearing 8 through the shaft hole 9.
[0027] like Figure 1 and Figure 2 As shown, it also includes a sealing gasket 3, which is arranged between the shaft fixing seat 5 and the outer surface of the box body around the shaft hole 9. In this embodiment, a sealing gasket 3 is arranged between the shaft fixing seat 5 and the outer surface of the box body around the shaft hole 9, and the sealing gasket 3 is O-shaped. The sealing gasket 3 can not only reduce the wear of the shaft fixing seat 5 and the box body, but also play a sealing role to prevent the water in the water tank from leaking out from the gap between the shaft fixing seat 5 and the outer surface of the box body around the shaft hole 9 through the shaft hole 9, thereby further improving the sealing performance of the box body.
[0028] like Figure 1 and Figure 2 As shown, the connecting piece is a fixed U-shaped seat 4, which is made by bending both ends of a square iron plate toward the middle, and the bottom of the fixed U-shaped seat 4 is fixed to the outside of the water tank around the shaft hole 9 by a fixing mechanism, and the two sides of the fixed U-shaped seat 4 are fixedly connected to the rowing machine frame.

A sealing ring (not shown in the figure) is provided between the upper box body 2 and the lower box body of this embodiment to ensure the sealing of the box body itself. The upper box body 2 and the lower box body can be connected by a variety of methods such as threaded connection or snap connection, and a suitable method can be adopted according to actual needs.
[0030] Further, the upper box body 2 is provided with a water injection hole (not shown in the figure), and the water injection hole is sealed by a sealing cover. The water injection hole of this embodiment is provided in the upper box body 2, and the water injection hole is sealed by a sealing cover. In other embodiments, the water injection hole can also be set at other positions.
[0031] Furthermore, the upper box 2 and the lower box are both made of polycarbonate material. Polycarbonate is a high-strength, high-toughness material with excellent impact resistance and high transparency, which makes the water quality inside the water tank clear at a glance, making it convenient for users to observe the water tank status at any time. Other materials may also be used in other embodiments.
[0032] The working process of the utility model is as follows:
[0033] When the user is rowing, the driving mechanism drives the rotating shaft 1 to rotate, and the rotation of the rotating shaft 1 drives the impeller inside the water tank to rotate, and the resistance generated by the impeller and the water is fed back to the user in time, thereby achieving the purpose of exercise. When the impeller rotates and drives the water in the water tank to splash onto the shaft hole 9, since the skeleton oil seal 7 is provided on the rotating shaft 1 inside the fixing mechanism, the skeleton oil seal 7 can seal the space between the bearing 8 and the shaft hole 9, thereby preventing the water inside the water tank from leaking out from the gap between the rotating shaft 1 and the bearing 8 through the shaft hole 9, and a sealing gasket 3 is provided between the shaft fixing seat 5 and the outer surface of the box around the shaft hole 9, so as to further improve the sealing performance, thereby achieving the function of sealing the water tank.
