[0026] See Figure 1-6As shown in the figure, as an embodiment of the present invention, a folding elliptical machine is provided, including a main frame 1, a guide rail frame 2, a handle swing arm 3, a crank arm 4, a pulley connecting rod 5, a foot pedal connecting rod 7, and a flywheel 9. The front end of the guide rail frame 2 is hinged to the rear end of the main frame 1 so that the guide rail frame 2 can be folded upward relative to the main frame 1. An elastically telescopic support member 10 is installed between the main frame 1 and the guide rail frame 2. The support member 10 is located on the lower side of the front end of the guide rail frame 2. The support member 10 is a gas spring. The gas spring has a simple structure, does not require an additional drive mechanism, and has a good support effect. Specifically, the guide rail frame 2 includes a U-shaped frame 2.1 and a hinge rod 2.2 connected to the front end of the U-shaped frame 2.1. The main frame 1 includes columns 1.1, a main frame 1.2, and a base 1.3 connected sequentially from top to bottom. The front end of the hinge rod 2.2 of the guide rail frame 2 is hinged to the rear end of the main frame 1.2. A locking assembly is installed on the upper side between the guide rail frame 2 and the main frame 1.2. The locking assembly includes a latch 11 and a connecting rod 12 that are hinged front to back. The front end of the latch 11 is hinged to the main frame 1.2, and the rear end of the connecting rod 12 is hinged to the hinge rod 2.2 of the guide rail frame 2. The flywheel 9 is rotatably mounted on the main frame 1, and the handle swing rod 3 rotates accordingly. The foot pedal connecting rod 7 is hinged to the bottom of the handle bar 3 on both sides of the main frame 1. A foot pedal 8 is installed at the rear end of the foot pedal connecting rod 7. The pulley connecting rod 5 is hinged to the foot pedal connecting rod 7. The front end of the pulley connecting rod 5 is rotatably connected to the flywheel 9 via a crank arm 4. The rear end of the pulley connecting rod 5 is slidably mounted on the upper side of the U-shaped frame 2.1 of the guide rail frame 2 via a pulley 6. The handle bar 3, crank arm 4, pulley connecting rod 5, and foot pedal connecting rod 7 are arranged in two units on the left and right sides, respectively. When the elliptical machine needs to be folded for storage, the rear end of the latch 11 is first lifted upwards to unlock the latch 11 and the connecting rod 12. Then, the rear end of the guide rail frame 2 is lifted forcefully, causing it to fold upwards relative to the main frame 1. This, in turn, causes the pulley connecting rod 5 and the foot pedal connecting rod 7 to fold upwards together. At this time, the gas spring is stretched elastically to support and lift the guide rail frame 2, thus realizing the folding and storage process of the elliptical machine. When the elliptical train needs to be unfolded, the pulley connecting rod 5, foot pedal connecting rod 7, and the rear end of the guide rail frame 2 are forcefully swung and pressed down relative to the main frame 1 until the guide rail frame 2 contacts the ground and is in a horizontal state, thus realizing the unfolding process. At this time, the gas spring is compressed and contracted by the guide rail frame 2, and the locking buckle 11 and the connecting rod 12 lock and fix it, thereby fixing and supporting the unfolded guide rail frame 2, thus realizing the unfolding and use of the elliptical trainer. This technical solution allows the guide rail frame 2, pulley connecting rod 5, and foot pedal connecting rod 7 to be folded upward relative to the main frame 1 for storage, occupying less space and making it convenient for storage and transportation.

[0027] In this embodiment, the latch 11 has a through hole 11.2 that runs through the front and rear. The front end of the connecting rod 12 is hinged to the rear end inside the through hole 11.2 of the latch 11. The bottom rear end of the latch 11 is provided with a clearance channel 11.3 for the connecting rod 12 to move and make room. In the unfolded use state, the inner top wall of the latch 11 blocks and limits the connecting rod 12, thereby locking and fixing the latch 11 and the connecting rod 12, and thus providing unfolded and fixed support for the guide rail frame 2.

[0028] In this embodiment, a handle lever 11.1 is provided on the top of the latch 11 extending backward. The handle lever 11.1 includes a horizontal section located on the upper side of the latch 11 and extending horizontally backward, and an inclined section located at the rear end of the horizontal section and extending upward at an angle. The handle lever 11.1 is provided to facilitate lifting the latch 11 to achieve the unlocking operation, thereby facilitating the folding and storage of the elliptical machine.

[0029] In this embodiment, height-adjustable first adjustment feet 13 are respectively installed on both sides of the bottom of the guide rail frame 2. By adjusting the height of the first adjustment feet 13, the top side of the guide rail frame 2 can maintain a balanced state, ensuring the comfort of the user when exercising on the elliptical machine.

[0030] In this embodiment, the base 1.3 is I-shaped, and the bottom of the base 1.3 is equipped with a second adjustable foot 14 with adjustable height. By adjusting the height of the second adjustable foot 14, the main frame 1 can maintain a balanced state. The rear side of the base 1.3 is equipped with a roller 15, so that when the elliptical machine is folded, the elliptical machine can be moved and transported by the roller 15.
