DETAILED DESCRIPTION

[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on that a person of ordinary skill in the art can realize, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope of the present application.

[0019] In the embodiments of the present application, as shown in the drawings, Figures 1-2 The present application provides an elliptical machine capable of adjusting the step distance, mainly comprising: a base frame 1; a main frame 2 installed on the top of the base frame 1; a return mechanism 3 comprising a return point 31 rotatable along a circular track, the return point 31 is provided with a connecting barrel 32 on the outside of the return mechanism 3, the return point 31 is provided with a movable part 33 on the inside of the return mechanism 3, the movable part 33 can fix the return point 31 by a plurality of locking hooks 34 provided inside the return mechanism 3; a first connecting rod 4, one end of which is hinged to one side of the main frame 2 and has a swing arm 41 extending at the hinge point; a second connecting rod 5, one end of which is hinged to the first connecting rod 4 and the other end is hinged to the connecting barrel 32, a pedal 51 is installed above the second connecting rod 5.

[0020] Specifically, the movable part 33 can be locked with the locking hook 34, so that the return point 31 of the movable part 33 is movable, and the distance between the return point 31 and the center of the rotating track can be changed according to the actual use requirement, so as to change the running track of the first connecting rod 4 and the second connecting rod 5 and further affect the step distance of the elliptical machine.

[0021] The following will continue to describe some preferred / improved embodiments based on the above embodiments, the following embodiments can be selected or combined.

[0022] Specifically, the side of the movable part 33 close to the main rotating direction of the return point 31 is provided with an L-shaped locking column 331, the L-shaped locking column 331 can be clamped by the locking hook 34, the L-shaped locking column 331 can be clamped by the locking hook 34 at all times under the support of the force below, so as to ensure that the L-shaped locking column 331 will not be separated from the locking hook 34 in the use state, preventing the sudden change of the step distance from causing adverse effects on the user's legs and feet.

[0023] Referring to Figure 2As shown, a movable rod 332 is installed at the bottom of the movable member 33, and a ball joint 333 is formed at one end of the movable rod 332. The inside of the winding mechanism 3 is provided with a ball joint groove 35 that cooperates with the ball joint 333. The ball joint 333 cannot disengage from the ball joint groove 35 and can slide within the ball joint groove 35. The presence of the ball joint 333 allows the movable member 33 to rotate slightly relative to the ball joint 333, which facilitates the removal of the L-shaped locking pin 331 from the locking hook 34.

[0024] Furthermore, an abutment portion 334 is formed on the movable rod 332, and a spring 36 is sleeved between the abutment portion 334 and the ball joint 333. The spring 36 abuts against one side of the abutment portion 334, and the spring 36 can drive the movable member 33 to always move outward, ensuring that the L-shaped locking pin 331 will not disengage from the locking hook portion 34 in the use state.

[0025] Specifically, the winding mechanism 3 has a first spring groove 37 and a second spring groove 38. The diameter of the first spring groove 37 is larger than the diameter of the second spring groove 38. One end of the spring 36 abuts against the bottom of the second spring groove 38. The maximum movement distance of the winding point 31 depends on the length of the first spring groove 37.

[0026] More specifically, the diameter of the first spring groove 37 is larger than the diameter of the abutment portion 334, and the abutment portion 334 can move within the first spring groove 37.

[0027] Preferably, the top of the abutment portion 334 and the top of the first spring groove 37 are both provided with inclined surfaces that can cooperate with each other, and the inclined surfaces can make the rotation of the movable part 33 smoother.
