[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be 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.

[0033] refer to Figure 1-Figure 7 As shown, the winding device of the utility model comprises a winding wheel 3, a rope 6 and a transmission assembly 4. A spiral groove 31 is concavely provided on the outer wall of the winding wheel 3.

[0034] The transmission assembly 4 includes a guide rail 41, a guide sleeve 42 and a paddle 43. The guide rail 41 is arranged on the outer side of the winding wheel 3, and the length direction of the guide rail 41 is parallel to the axial direction of the winding wheel 3. The guide sleeve 42 is sleeved on the guide rail 41, and the guide sleeve 42 is slidably connected to the guide rail 41, that is, the guide sleeve 42 can reciprocate along the length direction of the guide rail 41. The paddle 43 is convexly arranged on the side of the guide sleeve 42 facing the winding wheel 3, and the head of the paddle 43 extends into the spiral groove 31 of the winding wheel 3. The shape and size of the head of the paddle 43 are compatible with the shape and size of the groove wall of the spiral groove 31.

[0035] The rope 6 is wound in the spiral groove 31 of the reel 3, one end of the rope 6 is connected to the reel 3, and the other end is detached from the reel 3 to be connected to the handle assembly 7 used by the user during training.

[0036] When the winding wheel 3 rotates back and forth under the action of external force, the rotating winding wheel 3 utilizes the matching relationship between the spiral groove 31 and the paddle 43 to drive the paddle 43 to move, whereby the paddle 43 drives the guide sleeve 42 to move back and forth along the length direction of the guide rail 41 under the drive of the winding wheel 3, and the rope 6 is pulled out of the spiral groove 31 or reeled back into the spiral groove.

[0037] In the above-mentioned illustrative embodiment, by matching the transmission assembly 4 with the winding wheel 3, the winding wheel 3 drives the guide sleeve 42 to move back and forth axially when it rotates back and forth, so that the rope 6 can always be wound in the spiral groove 31 of the winding wheel 3 in a single-layer spiral shape, thereby avoiding the phenomenon of rope overlap during the pulling of the rope 6 and ensuring that the rope 6 is stable, thereby avoiding obvious frustration during the pulling of the rope 6, ensuring the continuity of the user's training movements, and ensuring the training effect.

[0038] refer to Figure 7 As shown, in some embodiments, there are two paddles 43, and a clamping groove 431 for accommodating the threads of the spiral groove 31 is formed between the two paddles 43; specifically, the clamping groove 431 is adapted to the threads of the spiral groove 31 within a pitch range; thereby, through the provision of the two paddles 43, the reliability of the matching relationship between the two paddles 43 on the winding wheel 3 and the guide sleeve 42 is improved, ensuring that the winding wheel 3 can stably and reliably drive the guide sleeve 42 to move synchronously when rotating.

[0039] refer to Figure 3 , Figure 4 As shown, in some embodiments, the guide sleeve 42 is further provided with a wire outlet 441 on the side facing the reel 3; the rope 6 extends outward through the wire outlet 441 to connect with the handle assembly 7 used by the user during training; specifically, the guide sleeve 42 is provided with a wire outlet drum 44 on the side facing the reel 3, and the wire outlet 441 is opened through the center of the wire outlet drum 44. The position of the wire outlet 441 on the guide sleeve 42 is directly opposite to the detachment point of the rope 6; it can be understood that the detachment point of the rope 6 is the position where the rope 6 detaches from the reel 3; relative to the reel 3, the position of the detachment point in the axial direction of the reel 3 changes continuously during the reel 6 retraction process, but relative to the wire outlet 441 on the guide sleeve 42, the position of the detachment point is fixed; further, the rope 6 between the detachment point and the wire outlet 441 is located in the tangential direction of the reel 3, thereby keeping the angle of the rope 6 between the detachment point of the rope 6 and the wire outlet 441 fixed, further improving the smoothness of the rope 6 retraction, minimizing the sense of frustration, and improving the continuity of the user's training movements.

[0040] refer to Figure 1 , Figure 2As shown, in some embodiments, the winding device further includes a wire pulley assembly 5 disposed above the wire outlet 441, the wire pulley assembly 5 includes two pulleys 51 disposed side by side, the slide grooves on the two pulleys 51 are matched to form a wire outlet channel 52, the rope 6 passing through the wire outlet 441 then extends outward through the wire outlet channel 52, and then connected to the handle assembly 7. Through the arrangement of the wire pulley assembly 5, the rope 6 is finally positioned and guided for outlet, ensuring that the final wire outlet 441 position of the rope 6 of the entire winding device is stable, and reducing the wear of the rope 6 when it is reciprocated and pulled.

[0041] refer to Figure 1-Figure 7 As shown, in some embodiments, the winding device further includes a base frame 1 and a resistance source 2. The base frame 1 includes a bottom plate 11, a first support plate 12 and a second support plate 13 connected to the bottom plate 11 and arranged opposite to each other. The resistance source 2 is connected to the side of the first support plate 12 away from the second support plate 13. The resistance source 2 has an output shaft 21, which passes through the first support plate 12 and the second support plate 13 and is rotatably connected thereto. The winding wheel 3 is sleeved on the output shaft 21 between the first support plate 12 and the second support plate 13. When the resistance source 2 is working, the output shaft 21 can be driven to rotate, thereby driving the winding wheel 3 to rotate synchronously to provide resistance for the winding device; it can be understood that it is not necessary to deliberately make a resistance source 2 with a longer torque shaft, and a longer output shaft 21 can be used to connect with the torque shaft of the resistance source 2 to transmit torque, so as to reduce the cost of the resistance source 2; an anti-rotation structure is provided between the winding wheel 3 and the output shaft 21 to ensure that the two rotate synchronously and no slipping occurs. The two ends of the guide rail 41 in the length direction are connected to the first support plate 12 and the second support plate 13 respectively. The rope 6 is connected to the end of the winding wheel 3 close to the first support plate 12. The outlet drum 44 on the guide sleeve 42 is located on the side of the paddle 43 facing the first support plate 12. Furthermore, the relative position relationship between the outlet port 441 on the guide sleeve 42 and the paddle 43 in the axial direction of the output shaft 21 is equivalent to a pitch of the spiral groove 31 on the winding wheel 3; when the rope 6 is pulled out, the spiral groove 31 that has just separated from the rope 6 quickly contacts the paddle 43 to achieve guidance, and when the rope 6 is wound, the spiral groove 31 that has just separated from the paddle 43 is quickly wrapped around the rope 6 to achieve the accommodation of the rope 6, thereby optimizing the length of the guide sleeve 42 and the winding wheel 3, making the overall structure of the winding device more compact, and realizing a miniaturized design.

[0042] To further illustrate, when the user overcomes the resistance of the resistance source 2 by means of the handle assembly 7 and pulls out the rope 6, the pulling force applied by the user drives the winding wheel 3 and the output shaft 21 of the resistance source 2 to rotate synchronously, and at the same time drives the guide sleeve 42 to translate along the length direction of the guide rail 41, that is, the axial direction of the output shaft 21 toward the first support plate 12 through the paddle 43, and the rope 6 on the winding wheel 3 gradually detaches from the winding wheel 3, and the length of the rope 6 extending through the outlet 441 on the guide sleeve 42 increases continuously; because the guide sleeve 42 translates under the action of the spiral groove 31 of the winding wheel 3, the movement of the guide sleeve 42 is stable and controllable, thereby achieving a smooth outlet of the rope 6; when When the pulling force applied by the user is less than the resistance of the resistance source 2, the resistance source 2 drives the winding wheel 3 to rotate in the opposite direction through its output shaft 21, and at the same time drives the guide sleeve 42 to translate along the length direction of the guide rail 41, that is, the axial direction of the output shaft 21 toward the second support plate 13 through the paddle 43, and the rope 6 is gradually wound into the spiral groove 31 of the winding wheel 3; because the guide sleeve 42 translates under the action of the spiral groove 31 of the winding wheel 3, the movement of the guide sleeve 42 is stable and controllable, so that the rope 6 can be smoothly wound back into the spiral groove 31 of the winding wheel 3, thereby avoiding the rope 6 from being wound multiple times at the same axial position of the winding wheel 3, and realizing the single-layer setting of the rope 6 on the winding wheel 3. In summary, when the user is training, he reciprocates and pulls the rope 6, and the winding wheel 3 rotates back and forth, while driving the guide sleeve 42 to move back and forth axially, so that the rope 6 is always wound in a single-layer spiral in the spiral groove 31 of the winding wheel 3, effectively avoiding the rope overlapping phenomenon during the pulling process of the rope 6, and keeping the pulling radius of the rope 6 stable, that is, the resistance arm is stable, so the resistance transmitted to the rope 6 by the resistance source 2 will not change due to the change of the arm, and the resistance felt by the user is synchronized with the resistance provided by the resistance source 2.

[0043] refer to Figure 1 , Figure 2 As shown, in some embodiments, the wire pulley assembly 5 further includes a U-shaped connecting plate 53; it can be understood that the U-shaped connecting plate 53 includes two side plates arranged opposite to each other, a connecting plate connected to the same end of the two side plates, and the connecting plate and the two side plates form an open accommodating cavity 531. The two ends of the U-shaped connecting plate 53 in the length direction are respectively connected to the first support plate 12 and the second support plate 13, and the two pulleys 51 are sandwiched side by side in the accommodating cavity 531 of the U-shaped connecting plate 53, and each pulley 51 is rotatably connected to the two side plates of the U-shaped connecting plate 53 through a rotating shaft.

[0044] refer to Figure 2 , Figure 3 , Figure 5As shown, in some embodiments, a bearing 15 is installed on the second support plate 13 at the penetration of the output shaft 21; specifically, a bearing seat 14 is installed on the second support plate 13, and the bearing 15 is connected to the bearing seat 14. The output shaft 21 of the resistance source 2 is inserted into the inner hole of the bearing 15, so that the output shaft 21 and the second support plate 13 are rotatably connected, and the base frame 1 can stably support the resistance source 2 and the output shaft 21.

[0045] In some embodiments, the resistance source 2 is a servo motor or a generator, that is, the resistance during training is provided by the servo motor or the generator; the resistance source 2 may also be other devices capable of providing rotational resistance. Furthermore, the rotational torque output by the servo motor is converted into a linear tension of the rope 6; as the user pulls the rope 6, the rope 6 is pulled out from the reel 3 or reeled back onto the reel 3, thereby achieving impedance training.

[0046] refer to Figure 1-Figure 4 , Figure 6 As shown, in some embodiments, at least one groove 411 is opened on the outer wall of the guide rail 41 along its length direction, and a convex rib 421 adapted to the groove 411 is convexly provided on the inner wall of the guide sleeve 42, and the convex rib 421 is slidably connected in the groove 411; thus, through the matching setting of the convex rib 421 and the groove 411, a sliding connection between the guide sleeve 42 and the guide rail 41 is achieved, ensuring that the guide sleeve 42 can only move back and forth along the guide rail 41 without relative rotation.

[0047] refer to Figure 1-Figure 7 As shown, based on the above-mentioned winding device, the utility model also provides a fitness device, including the above-mentioned winding device.

[0048] To sum up, the winding device and fitness equipment of the present invention can avoid the rope overlapping phenomenon during the pulling of the rope 6 and ensure the stability of the rope 6, thereby avoiding obvious frustration during the pulling of the rope 6, allowing the user to feel synchronous and consistent resistance, ensuring the continuity of the user's training movements and ensuring the training effect.

[0049] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
