Description

Technical Field

[0001] This application relates to the field of fitness equipment technology, and more specifically, to a three-dimensional cable mechanism and fitness device. Background Technology

[0002] Existing fitness equipment typically targets specific muscle groups or body parts for training. For example, leg curl machines are used to train the hamstrings, leg extension machines to train the quadriceps, lat pulldown machines to train the latissimus dorsi, and so-called "chest trainers" to train the chest muscles. While these machines can effectively train the target muscle groups, they often have the problem of only being able to perform a single type of exercise.

[0003] A search revealed that Chinese patent CN212090680U discloses a three-dimensional reversing circulating steel cable mechanism and a gantry frame with a three-dimensional reversing circulating steel cable mechanism. This device, by setting multiple pulleys, enables the circulating steel cable to achieve three-dimensional reversing of the steel cable while meeting the requirements of traditional closed-loop circulating steel cable.

[0004] While the aforementioned device can achieve three-dimensional reversal of the cable, its cable structure cannot output different tensile forces according to the user's exercise needs, thus failing to meet the user's requirements. Therefore, we propose a three-dimensional cable mechanism and fitness device. Utility Model Content

[0029] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0030] Example 1

[0031] Please see Figures 1 to 3 This application discloses a three-dimensional cable mechanism, including a support frame 1, a counterweight 2 vertically slidably connected within the support frame 1, and a movable pulley A201 fixedly mounted on the counterweight 2.

[0032] An adjusting component 4 is slidably connected to the support frame 1. The adjusting component 4 is fixed to the support frame 1 by bolts.

[0033] A steel cable A3 is provided on the support frame 1. The steel cable A3 passes over the lower surface of the movable pulley A201. Both ends of the steel cable A3 are free ends. Limiting components 7 are installed at both ends of the steel cable A3. One free end of the steel cable A3 is limited by the support frame 1 through the limiting component 7, and the other free end is limited by the adjusting component 4 through the limiting component 7, so as to maintain the tension of the steel cable A3.

[0034] A connector 5 is slidably connected inside the support frame 1. The sliding direction of the connector 5 is parallel to that of the adjusting component 4. The two ends of the connector 5 are respectively connected to the movable pulley B501 and the movable pulley C502. The steel cable A3 passes over the lower surface of the movable pulley B501.

[0035] A steel cable B6 is wound around the upper surface of the movable pulley C502. The two ends of the steel cable B6 are set as a fixed end and a free end. The fixed end of the steel cable B6 is connected and fixed to the adjusting component 4. The free end of the steel cable B6 is equipped with a limiting component 7. The free end of the steel cable B6 is limited by the supporting frame 1 through the limiting component 7 to maintain the tension of the steel cable B6.

[0036] By placing a counterweight on the counterweight seat 2, when the two free ends of the steel cable A3 are pulled, a pulling force of 1 / 2 of the total weight of the counterweight seat 2 can be output outward; when the free end of the steel cable B6 is pulled, a pulling force of 1 / 2 of the total weight of the counterweight seat 2 can also be output outward.

[0037] When adjusting the height of the adjusting component 4 on the support frame 1, only the position of the connecting component 5 is changed, without causing any change in the internal force of the steel cable A3 or steel cable B6, making it convenient for the user to adjust. By changing the position of the adjusting component 4, the distance between the two free ends of the steel cable A3 can be adjusted; when the two free ends of the steel cable A3 are separated, the user can choose either free end for exercise; when the steel cable A3 is brought together, the user can pull both free ends simultaneously, thereby outputting the pulling force of the total weight of the counterweight 2 outward.

[0038] Preferably, a movable pulley D8 is slidably connected within the support frame 1. Steel cable A3 passes over the lower surface of the movable pulley D8. A steel cable C9 is mounted on the support frame 1, with a fixed end and a free end at both ends. The fixed end of steel cable C9 is connected and fixed to the movable pulley D8, while the free end of steel cable C9 is limited by the support frame 1 via a limiting member 7, maintaining the tension of steel cable C9. By positioning the free end of steel cable C9 at a different location than the free ends of steel cables A3 and B6, for example, above the free ends of steel cables A3 and B6, the user can pull down on the free end of steel cable C9 for exercise. In this case, steel cable C9 can output the pulling force of the total weight of the counterweight 2, increasing the number of exercise points and methods available with this device.

[0039] Preferably, a fixed pulley A101 is fixedly installed on the support frame 1. A steel cable A3 passes over the upper surface of the fixed pulley A101. The fixed pulley A101 is located between the movable pulley A201 and the connecting member 5, and is positioned above both the movable pulley A201 and the connecting member 5. Fixed pulleys B102 are provided on both sides of the movable pulley D8, located above the movable pulley D8 and fixedly installed on the support frame 1. The steel cable A3 passes over the upper surfaces of both fixed pulleys B102. This configuration is used to control the three-dimensional orientation of the steel cable A3 within the support frame 1.

[0040] Preferably, the free end of steel cable A3 on the support frame 1 is close to the free end of steel cable B6. Users can not only pull the free ends of steel cable A3 on the support frame 1 and steel cable B6 separately for exercise, but also combine the free ends of steel cable A3 on the support frame 1, steel cable A3 on the adjusting member 4, and steel cable B6 to achieve a larger and more adjustable output pulling force.

[0041] Preferably, the limiting member 7 includes a limiting ball 701, a mounting bracket 702, and two fixed pulleys C703. Both fixed pulleys C703 are fixedly mounted on the mounting bracket 702. The diameter of the limiting ball 701 is larger than the gap between the two fixed pulleys C703. The free end of the steel cable A3 or steel cable B6 passes through the gap between the two fixed pulleys C703 and is connected and fixed to the limiting ball 701. The mounting bracket 702 is fixedly mounted on the adjusting member 4 and is rotatably mounted on the support frame 1.

[0042] When the mounting bracket 702 is fixedly installed on the adjusting member 4, it can keep the direction of the output tension of the free end of the steel cable A3 on the adjusting member 4 unchanged; when the mounting bracket 702 is rotatably installed on the support frame 1, it can change the direction of the output tension of the free end of the steel cable A3 on the support frame 1 and the free end of the steel cable B6, so as to meet the different usage needs of users.
