[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0029] See also Figures 1 to 6 As shown, the utility model is a motor-type two-end fixed tension fitness structure, including a resistance source 1, a reel 2 connected to the resistance source 1 and a traction member 3 wound on the reel 2, the resistance source 1 is used to automatically retract the traction member 3 pulled out by the user and wind it on the reel 2; a fixing mechanism 4 is provided on the fixed shaft 22 of the resistance source 1, the fixing mechanism 4 includes an extension component 5 and a fastener 6, the extension component 5 is located between the fastener 6 and the fixed shaft 22, and the fastener 6 is used to fix the extension component 5 on an external bearing member.

[0030] The present invention achieves the fixation of the resistance source 1 at different angles or heights by arranging fasteners 6 and extension components 5. For example, the extension component 5 is fixedly installed on an external support frame, so that the user can use the exercise equipment in multiple directions and angles, so that the user is no longer limited to the fixed exercise paths of ordinary exercise equipment, expands the exercise methods and ways of the exercise equipment, improves the exercise effect, and facilitates the user to use the exercise equipment in multiple scenarios, thereby increasing the scope of application of the exercise equipment.

[0031] During actual use of the motor-driven, fixed-end tension fitness structure, resistance source 1 provides reverse resistance. The user pulls on traction member 3 to overcome the reverse resistance of resistance source 1, causing spool 2 to rotate forward and traction member 3 to be pulled out. When the user releases traction member 3, resistance source 1, driven by the reverse resistance, causes spool 2 to rotate in the reverse direction, automatically reeling in the traction member 3 that the user has pulled out. This process repeats, with the user pulling traction member 3 forward and resistance source 1 reeling it in the reverse direction, thereby exercising the user and improving their arm strength.

[0032] Two sets of fixing mechanisms 4 are provided, one on each side of the resistance source 1, and the other on each end of the fixed axis 22 of the resistance source 1. Providing fixing mechanisms 4 at both ends of the fixed axis 22 of the resistance source 1 improves the symmetry and stability of the structure, allowing the device to withstand greater tension without deformation during use, while further increasing the stability and balance of the device, and improving its safety and stability.

[0033] During installation, the two sets of fixing mechanisms 4 are installed on two parallel supporting surfaces to provide support for users to exercise, such as door frames. They can also be installed on the ground or support frames, so that users are no longer limited to the fixed exercise paths of ordinary exercise equipment, which expands the exercise methods of exercise equipment, improves the exercise effect, and facilitates users to use exercise equipment in multiple scenarios, thereby increasing the applicability of exercise equipment.

[0034] Extension assembly 5 includes a support rod 7, a threaded rod disposed on fixed shaft 22 of resistance source 1, a threaded hole adapted for the threaded rod disposed at one end of support rod 7, and a fastener 6 connected at the other end of support rod 7. The threaded connection of support rod 7 allows for precise length adjustment, enhancing the flexibility and adaptability of the device to meet the needs of different users or exercise environments.

[0035] Fastener 6 includes a support plate 8, a stopper 9, and a connector 10. Support plate 8 is used to contact an external load-bearing member. Stopper 9 is located between support plate 8 and connector 10. Connector 10 is provided with a first protrusion 11 extending outward from connector 10 on the side away from stopper 9. First protrusion 11 is provided with a first groove 12, into which one end of extension assembly 5 extends. The provision of first groove 12 enables extension assembly 5 to be securely connected to fastener 6, increasing the firmness and reliability of the connection while facilitating assembly and disassembly.

[0036] During actual use, the end of the support plate 8 away from the limit member 9 is pressed against the door frame. In this way, the support plates 8 of the two sets of fixing mechanisms 4 are respectively pressed against the two sides of the door frame. Then, the support rod 7 is rotated by hand to extend or shorten the distance between the resistance source 1 and the fastener 6 until the support plates 8 of the two sets of fixing mechanisms 4 are firmly clamped between the two sides of the door frame, thereby fixing the entire motor-type two-end fixed tension fitness structure between the two door frames.

[0037] The side of the stopper 9 closest to the connector 10 is provided with an inclined guide surface 13, and the two ends of the stopper 9, which are separated from each other, are provided with limit plates 14, with the connector 10 located between the limit plates 14. The inclined guide surface 13 can conveniently guide the connector 10 into place, while the limit plates 14 provide additional support and restraint to prevent the device from moving or loosening during use.

[0038] A second protrusion 15 extending outward from the support plate 8 is provided on the side of the support plate 8 near the limiting plate 14, and a second groove 16 is provided on the limiting plate 14 to fit in with the second protrusion 15. This design allows the support plate 8 and the limiting plate 14 to fit tightly together, improving the stability and reliability of the overall structure.

[0039] Connector 10 has an inclined mating surface that abuts against inclined guide surface 13. The sum of the angles between inclined guide surface 13 and the horizontal plane and between the inclined mating surface and the horizontal plane is 180°. The combination of inclined guide surface 13 and the inclined mating surface allows connector 10 and retaining member 9 to fit tightly together, improving the stability and reliability of the overall structure.

[0040] The connecting member 10 is slidably engaged with the supporting plate 8. The limiting plate 14 is provided with a through hole 17, the connecting member 10 is provided with a strip groove 18, and the limiting plate 14 is provided with a latch 19, which passes through the through hole 17 and is received in the strip groove 18. The latch fixing method makes the installation and removal of the device easier and more convenient.

[0041] The resistance source 1 is an external motor and includes a housing 20, an electromagnetic mechanism 21 disposed within the housing 20, and a fixed shaft 22. The fixed shaft 22 extends beyond the housing 20 at both ends and is provided with a stator. The housing 20 and the electromagnetic mechanism 21 form a rotor that rotates on the fixed shaft 22 and sleeves onto the outer side of the stator. The housing 20 is fixedly connected to the reel 2. The electromagnetic mechanism 21 provides stable and adjustable resistance, suitable for exercise requirements of varying intensities, achieving better exercise results.

[0042] Specifically, the cross-sectional area of ​​the spool 2 in the direction of the central axis is smaller than that of the housing 20. The housing 20 is fixedly connected to the spool 2 and the cross-sectional area of ​​the spool 2 is smaller than that of the housing 20. Compared with the case where the traction member 3 is wound around the housing 20, the lever arm is reduced, so that the traction member 3 requires a greater pulling force to counteract the thrust of the electromagnetic mechanism 21 on the housing 20, achieving a better exercise effect, improving the working efficiency of the motor, and saving materials and avoiding resource waste.

[0043] Specifically, the wire wheel 2 and the housing 20 are connected as one body, so that the wire wheel 2 is more stable, and the traction member 3 is evenly stressed when being pulled and is not easy to shake.

[0044] Specifically, an annular groove is provided on the reel 2, and the central axis of the annular groove winding reel 2 is axially arranged along the reel 2. The annular groove is convenient for accommodating the traction member 3, so that the traction member 3 is restricted in the annular groove to prevent the traction member 3 from slipping out of the reel 2.

[0045] The traction member 3 is a drawstring, one end of which is connected to the reel 2, and the other end of which is provided with a pull ring 23. The design of the pull ring 23 is convenient for the user to grasp, thereby improving the convenience of use.

[0046] Specifically, the pull ring 23 is provided with a handle that fits over the pull ring 23. The pull ring 23 is provided with a battery compartment and a control panel assembly. The control panel assembly is provided with a wireless transmission module and adjustment buttons. The pull ring 23 is provided with a key that is compatible with the adjustment button. The control panel assembly is electrically connected to the resistance source 1. The control panel assembly is provided on the pull ring 23 for adjusting the resistance of the resistance source 1. The user can adjust the resistance of the equipment while holding the pull ring 23, which greatly facilitates user operation and makes the tension fitness equipment more intelligent.

[0047] Specifically, a locking assembly is provided on the fixed shaft 22, and the locking assembly includes a first plate and a second plate. One end of the first plate is connected to the fixed shaft 22, and the other end of the first plate is rotatably connected to the second plate. A notch is provided on the second plate, and the traction member 3 extends into the notch to limit the movement of the pull ring 23.

[0048] During installation, the second protrusion 15 extends into the second groove 16, and the limit member 9 and the support plate 8 are installed. The installed limit member 9 and support plate 8 are installed on two parallel support surfaces via bolts to provide support for the user's exercise. The two ends of the fixed shaft 22 of the resistance source 1 are respectively connected to the support rod 7, and the support rod 7 is installed on the fixed shaft 22 via threads and the length is adjusted. The support rod 7 extends into the first groove 12, and the connecting member 10 is installed on the support rod 7. The side of the connecting member 10 away from the first protrusion 11 contacts the limit plate 14, and the displacement of the connecting plate is limited by the inclined guide surface 13 and the limit plate 14 to prevent the connecting member 10 from moving or loosening during use, thereby improving the stability of the equipment; during exercise, the casing 20 rotates under the action of the electromagnetic mechanism 21, and the user pulls the pull ring 23 to rotate the reel 2. The rotating reel 2 drives the casing 20 to rotate and counteracts the force of the electromagnetic mechanism 21, thereby achieving the effect of exercising the user's arm strength.
