Description

[0002] With the continuous improvement of people's health awareness, the demand for fitness equipment is increasing. Traditional fitness devices mainly use single resistance output methods such as springs, hydraulic pressure or single steel cable systems to meet the exercise needs of users. However, these traditional devices have many limitations in function and use experience.

[0003] After searching, the existing Chinese patent CN212090680U discloses a three-dimensional variable direction circulating steel cable mechanism and a gantry frame with the three-dimensional variable direction circulating steel cable mechanism. The device, by setting multiple pulleys, well realizes the three-dimensional variable direction of the steel cable under the premise of meeting the use requirements of the traditional closed-loop circulating steel cable.

[0004] Since there is only a single steel cable output port in the above-mentioned device, the resistance output method and position are relatively single, which can only meet the exercise needs of specific muscle groups and is difficult to realize the simultaneous exercise of multiple parts of the body. In view of this, we propose a multi-proportion multi-output port steel cable driving mechanism and fitness device. CONTENT OF THE INVENTION

[0027] Preferably, both ends of the first steel cable 3 are located on the upper part of the support frame 1, the heights of both ends of the first steel cable 3 are different, and a pull-down handle is fixedly connected to both ends of the first steel cable 3. By placing a counterweight block on the counterweight seat 2, a user can perform pull-down, skiing and other exercise actions by pulling any one end of the first steel cable 3; when the end of the first steel cable 3 is pulled, the movable pulley B 401 is limited by the second steel cable 4, which exhibits the characteristics of a fixed pulley and does not affect the internal force of the first steel cable 3, and the tension inside the first steel cable 3 is half of the total weight of the counterweight seat 2 and the counterweight block.

[0028] Preferably, the free end of the second cable 4 is located at the lower part of the support frame 1, and the user can connect the free end of the second cable 4 to other exercise equipment for deep squat, rowing, leg lifting, etc. When pulling the free end of the second cable 4, the movable pulley B401 can move downward under the pulling of the second cable 4, and since the two ends of the first cable 3 are limited by the support frame 1 through the limiting piece, the internal force of the first cable 3 will increase, so that the counterweight seat 2 can be lifted upward; at this time, the internal force of the first cable 3 is the total weight of the counterweight seat 2 and the counterweight block.

[0030] When the first cable 3 or the second cable 4 is pulled, the internal force of the first cable 3 increases, which will exert an upward force on the connecting piece 6; and since the two ends of the third cable 5 are limited by the support frame 1, the connecting piece 6 cannot move, so that the movable pulley C601 exhibits the characteristics of a fixed pulley and does not affect the internal force of the first cable 3. When the free end of the third cable 5 is pulled downward, the third cable 5 can pull the movable pulley C601 downward through the movable pulley D602 and the connecting piece 6, and since the two ends of the first cable 3 are limited by the support frame 1 through the limiting piece, the internal force of the first cable 3 will increase, so that the counterweight seat 2 can be lifted upward; at this time, the internal force of the first cable 3 is half of the total weight of the counterweight seat 2 and the counterweight block. The free end of the third cable 5 is connected with a barbell mechanism on the support frame 1, so that the user can do downward pulling exercise with the help of the barbell.
