At the same time, the wire rope 8 will also drive the wire roller 21 to rotate, and further drive the rotating screw rod transmission connected with the wire roller 21 to rotate around its own stem axle axis.

[0043] Correspondingly, the rotating screw rod 12 rotates around its own stem axle axis, because the rotating screw rod 12 is threadedly connected with the sliding part 14, therefore, in the process of rotating the rotating screw rod 12, the sliding part 14 will slide forward and backward in the extension direction of the rotating screw rod 12. Because the first guide wheel 13 is arranged on the sliding part 14, in the process of sliding the sliding part 14 forward and backward along the rotating screw rod 12, the sliding part 14 will drive the first guide wheel 13 to slide forward and backward. Assuming that the part of the wire rope 8 around the wire roller 21 that is about to separate from the wire roller 21 is called the wire outlet end, in the process of pulling the wire rope 8, the wire outlet position of the wire outlet end on the wire roller 21 will change, and because the first guide wheel 13 can slide forward and backward relatively, therefore, the first guide wheel 13 can follow the synchronous movement of the above wire outlet position, so that the wire rope 8 can always keep in the horizontal length direction (such as the extension direction of the wire rope between the wire roller 21 and the wire outlet device first guide wheel can always keep Figure 12 indicated by the arrow), and there is no inclination angle.

[0044] In addition, it needs to be explained that the above motor is used for winding and unwinding the wire rope, and provides the required resistance for the exerciser.

[0058] As can be seen from the above description, the bottom plate and the two side plates form a U-shaped structure, wherein the rotating screw rod, the first guide rod and the second guide rod are all arranged on the two side plates, so that the sliding member slides in the U-shaped cavity formed by the mounting frame.

[0059] Further, the motor synchronous wire outlet mechanism, the rotating screw rod is provided with a bearing seat at both ends, the bearing seat includes a bearing 18 and a base 19, the bearing 18 is arranged in the base, and the bearing is sleeved on the rotating screw rod, and the base 19 is installed on the side plate.

[0060] As can be seen from the above description, the corresponding bearing seat is arranged, so as to facilitate the rotation of the rotating screw rod relative to the mounting frame.

[0061] Correspondingly, another purpose of the utility model is to provide a fitness equipment, which comprises a box body 3, a stand 4, a pedal 5 and the motor synchronous wire outlet mechanism as described above, the motor synchronous wire outlet mechanism is arranged in the box body 3, and the box body 3 is connected with the stand 4 and the pedal 5 respectively.

[0062] Please refer to Figures 1 to 14 The embodiment one of the utility model is: a fitness equipment, which comprises a box body 3, a stand 4, a pedal 5 and a motor synchronous wire outlet mechanism, the stand 4 is connected with the box body 3, the stand 4 extends along the vertical height direction, and the pedal 5 is rectangular in overall shape, and one end of the pedal 5 is connected with the box body 3.

[0063] In the embodiment, as Figure 2 、 Figure 8 、 Figure 9 And Figure 10As shown, a synchronous wire feeding mechanism for the motor is installed in the housing 3. The mechanism includes a motor 2 and a wire feeding device 1. A wire roller 21 is mounted on the motor 2, and parallel wire ropes 8 are wound around the wire roller 21. An output shaft is located at the end of the wire roller 21 furthest from the motor 2, and a transmission gear 22 is mounted on the output shaft. Correspondingly, as... Figure 8 as well as Figure 9 As shown, the cable outlet device 1 includes a mounting frame 11, a rotating screw 12, a first guide wheel 13, a sliding member 14, a rotating wheel 15, and two guide rods 16. Specifically: the rotating screw 12 is rotatably mounted on the mounting frame 11, the sliding member 14 is slidably sleeved on the rotating screw 12, and the sliding member 14 is threadedly connected to the rotating screw 12; the first guide wheel 13 is mounted on the sliding member 14; the two guide rods 16 are mounted on the mounting frame 11, and the sliding member 14 is slidably sleeved on the two guide rods 16. A rotating wheel 15 is provided at one end of the rotating screw 12 corresponding to the position of the aforementioned transmission gear 22. When the rotating wheel 15 rotates, it drives the rotating screw 12 to rotate around its own axis, thereby causing the sliding member 14 to slide back and forth in the extension direction of the rotating screw 12 and the guide rods 16. When the sliding member 14 slides back and forth, it drives the first guide wheel 13 mounted on the sliding member 14 to slide back and forth as well. To allow the rotating wheel 15 to rotate during use, in this embodiment, the transmission gear 22 on the output shaft is connected to the rotating wheel 15 on the cable outlet device 1 via a belt drive. The belt has meshing protrusions that mesh with the transmission gear 22. It should be noted that the motor 2 exerts a counterforce on the rotation of the cable roller 21, allowing the user to perform corresponding exercises by pulling the cable 8.

[0064] In actual use, the free end of the wire rope 8 on the wire roller 21 will extend outwardly around the first guide wheel 13.

At the same time, the wire rope 8 will also drive the wire roller 21 to rotate, thereby driving the transmission gear 22 on the output shaft to rotate. Correspondingly, the transmission gear 22 will also drive the rotating wheel 15 on the wire outlet device 1 to rotate when it rotates, and the rotating wheel 15 drives the rotating screw rod 12 to rotate around its own shaft axis. Since the rotating screw rod 12 is threadedly connected with the sliding piece 14, during the rotation of the rotating screw rod 12, the sliding piece 14 will slide back and forth in the extension direction of the rotating screw rod 12. Since the first guide wheel 13 is arranged on the sliding piece 14, during the back and forth sliding of the sliding piece 14 along the rotating screw rod 12, the sliding piece 14 will drive the first guide wheel 13 to slide back and forth. Assuming that the part of the wire rope 8 wound on the wire roller 21 that is about to be separated from the wire roller 21 is called the wire outlet end, during the pulling of the wire rope 8, the wire outlet position of the wire outlet end on the wire roller 21 will change, and since the first guide wheel 13 can slide back and forth relatively, the wire rope 8 can always maintain a horizontal length direction when it is output from the wire outlet position on the wire roller 21 to the guide wheel, and there is no inclination angle.

[0065] In this embodiment, as shown in Figure 10 , Figure 11 The mounting frame includes a bottom plate and two side plates arranged on the bottom plate, wherein the bottom plate and the two side plates form a U-shaped structure.

In actual use, the free end of the wire rope 8 on the wire roller 21 will sequentially pass through the first guide wheel 13, the first deflection wheel 31 and the second deflection wheel 32 and extend outward, and be connected with the stretching device 6.

[0067] In actual application, as shown in Figure 13 and Figure 14 in the drawings, the central axis of the first deflection wheel 31 is perpendicular to the unfolded pedal 5, and the central axis of the second deflection wheel 32 is parallel to the unfolded pedal 5. In detail, the first deflection wheel 31 and the second deflection wheel 32 are both concave wheels, the first deflection wheel 31 is located at the bottom of one side of the second deflection wheel 32, and the wire rope 8 enters the second deflection wheel 32 through the wire outlet position of the first deflection wheel 31 and is close to the second deflection wheel 32. Since the stretching device 6 is installed on the stand, the wire rope 8 winds the second deflection wheel 32 by one quarter of a circle, is led out and reaches the stretching device 6 in a direction parallel to the vertical rod on the stand. The deflection wheel set arranged in this way can ensure that the wire rope 8 can smoothly extend and retract relative to the box body 3, improve the working stability of the multifunctional fitness equipment, prevent the wire rope 8 from being stuck, and enhance the user's use experience.
