Wherein the flexible handrail (not shown) is mounted on the base 10; specifically, the flexible handrail is detachably connected with the base 10, and the flexible handrail can be used alone as fitness equipment or used together with the elliptical machine 100 with the flexible handrail removed after the flexible handrail is detached.

The elliptical machine frame 20 is a main structure of the elliptical machine 100, and is disposed on top of the base 10.

The turntable mechanism 30 is embedded in the elliptical machine frame 20; the turntable mechanism comprises two turntables connected through a rotating shaft, the rotating shaft is arranged inside the elliptical frame 20, the two turntables are respectively embedded on two sides of the inner surface of the elliptical frame 20, and each turntable is provided with an elliptical sliding rail.

The pulley assembly 40 is composed of a first pulley connecting rod, a second pulley connecting rod and a pulley, wherein the first pulley connecting rod and the second pulley connecting rod are respectively and fixedly connected with the pulley; one end of the first pulley connecting rod is clamped in an elliptical slide rail on the turntable mechanism 30, and the other end of the first pulley connecting rod is fixedly connected with a pulley; one end of the second pulley connecting rod is fixedly connected with the pulley.

The bottom surface of the foot pedal 50 is fixedly connected with the other end of the second pulley connecting rod.

The transmission device 60 is fixedly connected with the front end of the pedal 50 respectively; fixedly connected with the elliptical machine frame 20.

The connection relation of the structures comprises: because the second pulley connecting rod in the pulley assembly 40 is fixedly connected with the bottom surface of the pedal 50, when the pedal 50 starts to move, the pulley assembly 40 is driven to move along with the pedal 50 by the second pulley connecting rod, and the first pulley connecting rod in the pulley assembly 40 is buckled in the elliptical sliding rail embedded on the turntable mechanism 30, so that the pulley assembly 40 drives the first pulley connecting rod to move according to the track of the elliptical sliding rail, and meanwhile, the pedal 50 is also limited to move according to the track of the elliptical sliding rail. When the pedal 50 moves along the track of the elliptical slide rail, the transmission device 60 connected with the front end of the pedal is also driven to move.

Further, the transmission device 60 includes a first transmission link 61, a movable bearing 62, a second transmission link 63, and a fixed bearing 64. Wherein, the first transmission connecting rod 61 and the second transmission connecting rod 63 are both fixedly connected with the movable bearing 62, the second transmission connecting rod 63 is fixedly connected with the fixed bearing 64, and the fixed bearing 64 is fixedly connected with the elliptical machine frame.

The connection relation of the structures comprises: when the foot pedal 50 moves, the movable bearing 62 is driven by the first transmission connecting rod 61 to move, and one end of the second transmission connecting rod 63 is driven by the movable bearing 62 to move, and the fixed bearing 64 is fixedly connected with the elliptical machine frame, so that the other end of the second transmission connecting rod 63 is fixed, and the second transmission connecting rod swings left and right around the center of the fixed bearing.

In the above application principle, when the user uses the elliptical machine, the user can grasp the flexible handrail (not shown in the figure) with the tail end mounted on the base, and steps on the foot rest 50, when the user applies force forward, the foot rest 50 moves through the pulley assembly 40 according to the track of the elliptical sliding rail arranged on the turntable mechanism 30, and meanwhile, the foot rest 50 drives the transmission device 60 to move, so that the movement track of the foot rest 50 is limited to an ellipse by the turntable mechanism 30 and the transmission device 60 when the user uses the elliptical machine, the stride is longer than that of the conventional elliptical machine, the movement amplitude can be expanded more, and the exercise device is more comfortable to use and achieves the optimal exercise effect.

Referring to fig. 2, fig. 2 is a schematic structural view of the movable bearing 62 in fig. 1. The movable bearing 62 includes a movable rotating shaft 621 and a semi-open bearing housing 622, wherein the semi-open bearing housing 622 is detachably connected with the movable rotating shaft 621 through a fixing piece, the first transmission rod 61 is fixedly connected with the movable rotating shaft 621, and the second transmission rod 63 is also fixedly connected with the movable rotating shaft 621. In contrast, the connection of the first transmission rod 61 to the movable rotary shaft 621 forms a cavity opening 623 with the semi-open bearing housing 622, and a flexible shield 624 is provided in the cavity opening 623; wherein the flexible shield 624 is used to shield the cavity opening 623. It will be appreciated that the flexible shielding member 623 may be embedded in the cavity opening 623 or may be wrapped around the cavity opening 623, so as to ensure that the cavity opening 623 is always in a shielded state during use of the elliptical machine 100, and prevent foreign objects from entering.

It should be noted that, the movable rotating shaft 621 is fixed relative to the semi-open casing 622; the fixed bearing 64 includes a fixed rotating shaft and a semi-open housing, which is detachably coupled to the semi-open housing, wherein the semi-open housing is fixed to the elliptical machine frame 20 and the fixed rotating shaft is rotatable with respect to the semi-open housing.

In the above application principle, when the user steps on the pedal 50, the first transmission rod 61 drives the movable rotation shaft 621 to move, the movable rotation shaft 621 drives one end of the second transmission rod 63 to move, and the other end of the second transmission rod 63 is fixedly connected with the fixed rotation shaft of the fixed bearing, and the fixed rotation shaft is rotatable relative to the semi-open shell, so that the second transmission link 63 swings left and right about the center of the fixed bearing. As can be seen in fig. 2, there is no gap at the connection between the second transmission rod 63 and the movable rotation shaft 621, and the movable rotation shaft 621 moves along with the pedal 50 during exercise, so that a cavity opening 623 formed by the connection between the first transmission rod 61 and the movable rotation shaft and the semi-open bearing housing 622 also moves continuously, and a safety accident is caused if a child carelessly stretches his or her hand into the cavity opening.

In this embodiment, by providing a flexible shield 624 at the cavity opening 623, such safety accidents can be prevented.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
