[0071] The upper cover 512 is covered above the fixed seat 511. Threaded holes are respectively formed at positions corresponding to the upper ends of the upper cover 512 and the fixed seat 511. The countersunk socket head cap screws pass through the threaded holes to fixedly connect the upper cover 512 and the fixed seat 511;

[0072] The lower cover 513 is in an L-shaped structure. The lower cover 513 is covered below the fixed seat 511. It should be noted that an avoidance groove is formed at a position corresponding to the first connecting member 53 on the lower cover 513, which is convenient for installing the lower cover 513; for the sake of improving the aesthetics, the contact part between the lower cover 513 and the upper cover 512 is set to be airtight.

[0083] The intermediate shield 515 is fixedly arranged on the fixed seat 511, and both ends of the intermediate shield 515 are located below the retaining edge 5151. The intermediate shield 515 is configured to block the gap between the two groups of guide rails 52, and the intermediate shield 515 is made of aluminum alloy material.

[0084] Specifically, by providing the intermediate shield 515, the aesthetic effect and the use safety of the elliptical machine can be improved, and the protection effect can be enhanced.

[0085] In some other embodiments of the present application, the shield member 51 further includes a fixing plate 517, and the intermediate shield 515 is connected to the fixed seat 511 through the fixing plate 517.

[0086] Specifically, use hexagon socket head cap screws to connect the fixing plate 517 to both ends of the intermediate shield 515 from below the fixing plate 517 and the intermediate shield 515, then place the intermediate shield 515 in the middle position between the two groups of guide rails 52 and adjust the position, and sequentially use cross recessed large flat head screws, spring washers, and flat washers to connect the fixing plate 517 and the fixed seat 511 together, thereby fixing the position of the intermediate shield 515.

[0087] During the actual installation process, attention should be paid to the installation sequence. First, fix the guide rail 52 and the fixed seat 511, then fix the intermediate shield 515 and the fixed seat 511, and then use countersunk hexagon socket head screws to fixedly connect the lower cover shell 513 and the end of the fixed seat 511. Then, buckle the two side covers 514 on both sides of the guide rail 52 to both sides of the guide rail 52, and fasten the lower cover shell 513, the side covers 514, and the fixed seat 511 together through countersunk hexagon socket head screws. Finally, use countersunk hexagon socket head screws to fix the upper cover shell 512 on the fixed seat 511.
