Description

Technical Field

[0001] This utility model relates to the field of rowing machine technology, specifically to a rowing machine with an external flywheel. Background Technology

[0002] An external flywheel rowing machine is a highly efficient fitness device that simulates rowing on water. Its core design involves placing the flywheel system at the front of the machine, providing smooth resistance through magnetic control or aerodynamic technology. This structure makes the rowing motion more closely resemble the real rowing experience, with a natural and smooth movement trajectory, while reducing machine vibration and noise. The external flywheel allows for intuitive adjustment of resistance intensity. Combined with an ergonomic seat and adjustable foot pedals, it comprehensively works the muscles of the lower back, legs, hips, and arms, making it suitable for home and gym use, offering both low impact and high fat-burning effects.

[0004] The aforementioned prior art discloses a multi-functional rowing machine that, through a reversing mechanism and locking bolts, can be unfolded during use to enhance its effectiveness. Furthermore, the addition of elastic ropes further expands its functionality, allowing it to achieve different exercise goals. However, this multi-functional rowing machine cannot be adjusted according to the user's physical condition. Therefore, a rowing machine with an external flywheel is proposed. Utility Model Content

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1-7As shown, a rowing machine with an external flywheel includes a base 1, a flywheel 6 that can rotate on the top of the base 1, a seat cushion 23 that can be close to or away from the flywheel 6 on the top of the base 1, a support 2 that is fixed to the upper end of the base 1 and supports an adjustment mechanism 3, and an adjustment mechanism 3 that is located on the side of the support 2 close to the flywheel 6. A fixing seat 5 is fixed to the upper end of the base 1, and a rotating mounting shaft 51 is horizontally installed on the top of the fixing seat 5.

[0032] A second mounting post 63 is horizontally fixed on the side of the flywheel 6 away from the fixed base 5;

[0033] The adjustment mechanism 3 includes a mounting rod 31 with one end hinged to the support 2. A connecting frame 33 that can move along its central axis is mounted on the mounting rod 31. The end of the connecting frame 33 away from the mounting rod 31 is respectively hinged to the second mounting column 63.

[0034] A spring 34 is fitted on the outside of the mounting rod 31, and a limiting nut 32 is installed on the other end of the mounting rod 31 to limit the spring 34. The limiting nut 32 is threadedly engaged with the mounting rod 31.

[0035] When an external force drives the flywheel 6 to rotate, the flywheel 6 drives the connecting frame 33 to move axially along the mounting rod 31 via the second mounting post 63. During this process, the connecting frame 33 compresses the spring 34, causing the spring 34 to undergo elastic deformation and store elastic potential energy. When the external force applied to the flywheel 6 is removed, the elastic potential energy stored in the spring 34 acts on the connecting frame 33 through an elastic restoring force. The spring 34 drives the connecting frame 33 to move axially in the opposite direction along the mounting rod 31, and finally drives the flywheel 6 to return to its initial position via the second mounting post 63. The axial position of the limiting nut 32 can be adjusted by rotating it, thereby changing the amount of compression of the spring 34 by the limiting nut 32, and realizing the quantitative adjustment of the preload of the spring 34. When the limiting nut 32 is screwed in towards the spring 34, the compression ratio of the spring 34 increases, and the resistance load of the spring 34 increases accordingly. Conversely, when the limiting nut 32 is screwed out, the compression ratio of the spring 34 decreases, and the resistance load of the spring 34 decreases. The flywheel load is continuously adjustable, effectively solving the technical problem that traditional rowing machine training devices cannot adapt to the different physical fitness differences of different users.

[0036] See Figure 3 As shown, the upper surface of the base 1 is also fixed with a fixed seat 5 for supporting the flywheel 6. The top of the fixed seat 5 is horizontally mounted with a rotatable mounting shaft 51, and the center of the flywheel 6 is fixed on the mounting shaft 51.

[0037] To ensure the stable operation of the flywheel 6, a rotatable mounting shaft 51 is installed at the top of the fixed base 5. When the flywheel 6 rotates, the flywheel 6 will drive the mounting shaft 51 to rotate synchronously, ensuring the effective rotation of the flywheel 6.

[0038] See Figure 6 and Figure 7 As shown, the top of the support 2 is fixed with a limiting slide rail 21 for limiting the movement direction of the seat cushion 23;

[0039] A rotatable threaded rod 22 is horizontally installed inside the support 2;

[0040] The bottom of the cushion 23 is fixed with a slide 231 that can be threaded with the threaded rod 22. The slide 231 has a sliding hole 232 that can slide along the limiting slide rail 21.

[0041] By installing a handwheel 221 at one end of the threaded rod 22, the user can rotate the handwheel 221, causing the threaded rod 22 to rotate. Simultaneously, the rotation of the threaded rod 22 moves the slide 231 horizontally. As the slide 231 moves, it also moves the top cushion 23 synchronously, thus adjusting the position of the cushion 23. This allows the cushion 23 to be adjusted according to the user's actual needs. While the slide 231 moves, the sliding hole 232 on the slide 231 can slide along the limiting slide rail 21, effectively preventing the slide 231 from shifting during movement.

[0042] See Figure 1 , Figure 2 and Figure 3 As shown, a linkage frame 7 is provided on the side of the flywheel 6 away from the fixed base 5, and the top of the linkage frame 7 is fixed to the side of the mounting shaft 51 near the flywheel 6.

[0043] The flywheel 6 is fixed with a first mounting post 62 on the side away from the fixed base 5;

[0044] The bottom end of the linkage frame 7 is hinged to the first mounting post 62, and the top end of the linkage frame 7 is fixed with a handle 71 for manipulating its rotation around the central axis of the mounting shaft 51.

[0045] The user holds the handle 71 and pulls it, causing the handle 71 to rotate the linkage frame 7 around the central axis of the mounting shaft 51. At the same time, as the linkage frame 7 rotates, its bottom end cooperates with the first mounting post 62 to drive the flywheel 6 to rotate synchronously around the central axis of the mounting shaft 51.

[0046] See Figure 3 As shown, the bottom of both sides of the fixed base 5 is symmetrically provided with arc-shaped grooves 52;

[0047] The flywheel 6 is provided with an annular slide rail 61 at the edge of the side near the fixed base 5, which can slide along the arc-shaped slide groove 52.

[0048] To ensure the stability of the flywheel 6, an annular slide rail 61 is provided on the edge of the flywheel 6 near the fixed base 5. When the flywheel 6 rotates around the central axis of the mounting shaft 51, the flywheel 6 will slide along the arc-shaped groove 52 through the annular slide rail 61, effectively preventing the flywheel 6 from deviating during rotation, thereby ensuring the stability of the flywheel 6.

[0049] See Figure 1 and Figure 2 As shown, brackets 4 are symmetrically fixed on both sides of the flywheel 6, and a fixing frame 41 is longitudinally fixed at the bottom of the bracket 4. Multiple pedal rods 42 are arranged at equal intervals along the vertical direction on one side of the fixing frame 41.

[0050] By equidistantly setting multiple foot pedals 42 on one side of the fixed frame 41, users can choose the foot pedal position according to their own needs.

[0051] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
