[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figures 1 to 5 As shown, the automatic wire-reeling mechanism of the fitness equipment of the present invention is applied to the pull-rope 40 type fitness equipment, and can realize automatic wire-reeling in normal use and in power-off conditions.

[0043] The automatic wire-reeling mechanism of the fitness equipment of the utility model specifically comprises a frame 10, a driving assembly 20, a wire-reeling assembly 30 and a pull rope 40; the pull rope 40 is connected to the driving assembly 20, and the driving assembly 20 drives the pull rope 40 to be retracted to achieve automatic wire-reeling and provide exercise resistance; the pull rope 40 is connected to the wire-reeling assembly 30, and in the case of power failure, the wire-reeling assembly 30 drives the pull rope 40 to be retracted to achieve wire-reeling.

[0044] Specifically, the driving assembly 20 includes a driving module 21 mounted on the frame 10, and a first winding drum 22 drivingly connected to the driving module 21; the driving module 21 drives the first winding drum 22 to rotate. The wire take-up assembly 30 includes a box body 31 mounted on the frame 10, a second winding drum 32 rotatably connected to the inner side of the box body 31, and a spring 33 mounted on the inner side of the box body 31; one end of the spring 33 abuts against the second winding drum 32, and the other end of the spring 33 abuts against the inner side of the box body 31, and the spring 33 drives the second winding drum 32 to rotate and reset. One end of the pull rope 40 is fixed to the outer side of the first winding drum 22, and the pull rope 40 is wound around the outer sides of the first winding drum 22 and the second winding drum 32 in sequence.

[0045] When powered on, the driving component 20 and the take-up component 30 work simultaneously, the driving module 21 drives the first winding drum 22 to rotate, the elastic force of the mainspring 33 drives the second winding drum 32 to rotate, and drives the pull rope 40 to be recovered, thereby realizing automatic winding. At the same time, the output tension of the driving module 21 can simulate exercise resistance and improve the exercise effect.

[0046] In case of power failure, the drive module 21 cannot work normally, but the wire take-up assembly 30 can still work normally. The spring 33 is reset under the action of elasticity, driving the second winding drum 32 to rotate, thereby retracting the pull rope 40 and taking up the wire.

[0047] A further improvement to the above scheme is that the frame 10 includes a first mounting plate 11, a side plate 12 and a second mounting plate 13 connected in sequence, the first mounting plate 11, the side plate 12 and the second mounting plate 13 form a U-shaped structure, the driving assembly 20 is arranged between the first mounting plate 11 and the second mounting plate 13; the first mounting plate 11 is equipped with a connecting frame 14, and the wire take-up assembly 30 is arranged on the connecting frame 14. In actual application, the frame 10 is assembled on fitness equipment for use.

[0048] A further improvement to the above scheme is that the drive module 21 uses a motor, which can control the output torque to provide suitable exercise resistance. The drive module 21 is provided with a rotating part 211, and a connecting hole 221 is penetrated on the first winding drum 22. The connecting hole 221 is plugged with a fixing bolt 222 to fix the first winding drum 22 and the rotating part 211. The drive module 21 is provided with a guide column 23, and the two ends of the guide column 23 are provided with a flat position 231 and a thread 232. The guide column 23 is fixedly connected to the frame 10 through the thread 232 and the flat position 231. The drive module 21 drives the rotating part 211 to drive the first winding drum 22 to rotate on the outside of the guide column 23.

[0049] A further improvement to the above scheme is that the box body 31 includes an upper cover 311 and a lower cover 312 that are assembled and connected. A first abutment block 313 is convexly provided on the inner side of the lower cover 312, and a second abutment block 321 is convexly provided on the lower end of the corresponding second winding drum 32. One end of the spring 33 abuts against the first abutment block 313, and the other end of the spring 33 abuts against the second abutment block 321. When the user exercises, the pull cord 40 is pulled out, so that the spring 33 is deformed. After the user releases the pull cord 40, the spring 33 is reset under the action of elasticity, thereby driving the second winding drum 32 to rotate and retract the pull cord 40.

[0050] A further improvement to the above scheme is that, in order to improve the stability of use, a first connecting part 331 is provided at one end of the spring 33, and a second connecting part 332 is provided at the other end of the spring 33, wherein the first connecting part 331 and the second connecting part 332 are both U-shaped structures, the first connecting part 331 is buckled on the first abutment member, and the second connecting part is buckled on the second abutment member, so that the spring 33 is not easy to loosen, providing connection stability.

[0051] A further improvement to the above scheme is that a rotating shaft 34 is fixedly provided on the inner side of the box body 31, a rotating hole 322 is provided in the center of the second winding drum 32, and the rotating shaft 34 is rotatably connected in the rotating hole 322 so that the second winding drum 32 can rotate on the outer side of the rotating shaft 34. Furthermore, a bearing 35 is sleeved on the outer side of the rotating shaft 34, and the bearing 35 is arranged inside the rotating hole 322, which can improve the rotation stability.

[0052] Compared with the prior art, the automatic wire-winding mechanism of the fitness equipment involved in the utility model can realize automatic wire-winding and has good exercise effect; specifically, a driving component 20, a wire-winding component 30 and a pull rope 40 are provided, wherein the pull rope 40 passes through the driving component 20 and the wire-winding component 30 in sequence; the driving component 20 includes a driving module 21 and a first wire reel 22. Under normal use, the driving module 21 drives the first wire reel 22 to rotate to realize automatic wire-winding and provide exercise resistance; the wire-winding component 30 includes a spring 33 and a second wire reel 32. In the case of power failure, under the action of the elastic force of the spring 33, the second wire reel 32 rotates and resets to realize automatic wire-winding, thereby ensuring automatic wire-winding in the case of power failure and ensuring exercise safety, and the use of the spring 33 can improve the stability of wire-winding.

[0053] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
