[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figures 1 to 6As shown, a riser folding elliptical machine is characterized in that it includes a main body base 1, the main body base 1 is provided with an outer shell 2, the main body base 1 is provided with a fixing frame 3, the upper side of the fixing frame 3 passes through the outer shell 2 to the upper side position of the outer shell 2, the upper side of the fixing frame 3 is provided with a rotating frame 4, the bottom of the rotating frame 4 is provided with an arc-shaped fixing plate 5, the fixing frame 3 is provided with a penetrating transverse fixing hole 31 and a longitudinal fixing hole 32, the arc-shaped fixing plate 5 is provided with a first fixing hole 51 and a second fixing hole 52 corresponding to the transverse fixing hole 31 and the longitudinal fixing hole 32, and the arc-shaped fixing plate 5 is connected to the transverse fixing hole 31 and the longitudinal fixing hole 32 at the positions of the first fixing hole 51 and the second fixing hole 52 respectively by fasteners.

[0025] The vertical pipe is formed by assembling the fixed frame 3 and the rotating frame 4. In this way, during the transportation after production, the fixed frame 3 and the rotating frame 4 can be disassembled, so that the rotating frame 4 can be rotated, and then the rotating frame 4 can be folded to a position close to the main body base 1. This can reduce the space occupied by the column, thereby facilitating the packaging of the product after production and the transportation process. When using it, the user only needs to use fasteners to complete the installation. The horizontal fixing holes 31 and the longitudinal fixing holes 32 used can ensure the connection strength between the fixed frame 3 and the rotating frame 4 after fixation, thereby ensuring the normal use of the vertical pipe.

[0026] The arcuate fixing piece 5 serves as an intermediate structure connecting the fixed frame 3 and the rotating frame 4. Therefore, the arcuate fixing piece 5 and the rotating frame 4 need to be better fixed. In this embodiment, the arcuate fixing piece 5 and the rotating frame 4 are fixed by welding. Welding the arcuate fixing piece 5 and the rotating frame 4 facilitates production and processing. Compared with fastener connection, it also reduces the number of parts, thereby facilitating the user's subsequent assembly process.

[0027] The fixed frame 3 and the rotating frame 4 are secured together by the arc-shaped fixing piece 5. Therefore, to ensure the strong fixing strength between the fixed frame 3 and the rotating frame 4, the strong fixing strength between the arc-shaped fixing piece 5 and the fixed frame 3 must be ensured. Specifically, in this embodiment, two longitudinal fixing holes 32 are provided, one above the other, located on the upper side of the fixed frame 3, and the transverse fixing hole 31 is located between the two longitudinal fixing holes 32. In this case, the longitudinal fixing holes 32 and the transverse fixing holes 31 are arranged perpendicularly, and the transverse fixing hole 31 is located between the two longitudinal fixing holes 32. This ensures that the fixed frame 3 and the rotating frame 4 are more firmly secured after they are secured together.

[0028] To enhance the strength of the curved fixing plate 5 after being fixed to the fixing frame 3, in this embodiment, the curved fixing plate 5 has a U-shaped cross-section and includes a curved surface 51 adapted to fit the fixing frame 3. The curved surface 51 has fixing planes 52 at both outer ends. A fixing platform corresponding to the fixing planes 52 is provided on the outer side of the fixing frame 3, and the longitudinal fixing hole 32 is located at the location of the fixing platform. In this case, the fixing frame 3 is a circular tube structure. Therefore, the curved fixing plate 5 is provided with the curved surface 51. This allows the curved fixing plate 5 to abut against the fixing frame 3 on one side. The transverse fixing hole 31 is located at the location of the curved surface 51, thereby further abutting the curved fixing plate 5 against the fixing hole. The longitudinal fixing hole 32 is located on the side away from the curved surface 51. The fixing platform provided on the outer side of the fixing frame 3 now abuts against the fixing plane 52 of the curved fixing plate 5. The curved fixing plate 5 is secured to the fixing frame 3 on the U-shaped opening side via the longitudinal fixing hole 32 and fasteners, thereby enhancing the secure connection between the curved fixing plate 5 and the fixing frame 3.

[0029] At this time, since the column is composed of two parts, the fixed frame 3 and the rotating frame 4, and the connection is located on the upper side of the main body base 1, in order to ensure the overall aesthetics and prevent the user from accidentally touching the connection and scratching it during use, in this embodiment, a protective shell 6 is further provided on the upper side of the outer shell 2. The protective shell 6 includes a first protective shell 6 and a second protective shell 6, which are fixed by fasteners. The first protective shell 6 and the second protective shell 6 are arranged on the outside of the arc-shaped fixing plate 5 to surround the connection between the fixed frame 3 and the movable frame. The first protective shell 6 and the second protective shell 6 are used to wrap the connection, so that the connection between the fixed frame 3 and the rotating frame 4 can be hidden, thereby ensuring aesthetics and safety during use.

[0030] For the elliptical machine, in this embodiment, the elliptical machine also includes a pedal 71 assembly, and the pedal assembly includes a pedal 71, one end of the pedal 71 is rotatably connected to the armrest 72, and the other end is rotatably connected to the disc, the upper side of the armrest 72 is rotatably connected to the rotating frame 4 through a rotating rod, and the disc is connected to the flywheel 8 through a belt.

[0031] Furthermore, in order to realize the rotation of the pedal 71 and the armrest 72, a U-shaped fixing plate 9 is fixed at one end of the pedal 71, and rotation holes are provided at both ends of the U-shaped fixing plate 9. The lower side of the armrest 72 is connected to the U-shaped fixing plate 9 at the rotation hole through a rotating rod.

[0032] The flywheel 8 needs to rotate during use. At this time, in order to facilitate the installation of the flywheel 8, in this Seras, the main body base 1 also includes a transverse bracket 10. A U-shaped fixing frame 3 is provided on the upper side of the transverse bracket 10. The U-shaped fixing frame 3 includes two parallel side plates 111.

The flywheel 8 is clamped in the inclined groove 112 through the rotating shaft. The flywheel 8 is clamped in the inclined groove 112 through the rotating shaft, and then limit nuts are provided at both ends of the rotating shaft. The flywheel 8 will be tightly clamped in the inclined groove 112 under the pulling action of the belt, thereby realizing the installation of the flywheel 8. At this time, no bearing is required, and the rotation resistance of the flywheel 8 can be increased, thereby improving the exercise efficiency of the elliptical machine.

[0033] To ensure proper rotation of the flywheel 8, the belt must be kept taut. In this embodiment, an adjustment structure 12 for adjusting the belt tension is provided on the outside of the belt. The adjustment structure 12 includes an adjustment wheel 121 located on the outside of the belt and abutting against the belt. The adjustment wheel 121 is secured to the side plate 111 of the U-shaped fixing frame 3 via an adjustment bracket 122. The side plate 111 is provided with an adjustment hole and an adjustment slot 113. The adjustment slot 113 is arc-shaped, centered around the adjustment hole. One end of the adjustment bracket 122 is connected to the adjustment hole via a fastener. A raised shaft is provided in the middle of the adjustment bracket 122, which is positioned within the adjustment slot 113. Fasteners are provided on the outside of the raised shaft, securing the adjustment bracket 122 at a predetermined angle. Adjusting the position of the raised shaft within the adjustment slot 113 allows the adjustment wheel 121 to be adjusted, thereby adjusting the belt tension and ensuring proper operation of the flywheel 8.
