Description

Technical Field

[0001] This utility model relates to fitness equipment, and in particular to a multi-rope mechanism for a fitness device. Background Technology

[0002] With increasing health awareness, more and more fitness equipment is entering ordinary households. Among these machines, some use rope-based exercises, such as the cable reel in a rowing machine. Typically, the cable reel is connected to a lever. When the lever is pulled, the cable is extended, causing the reel to rotate and tighten a spring inside. This rotation also drives a wheel, which in turn rotates a damping wheel. The damping wheel, in turn, dampens the user's pull on the lever. When the user releases the lever, the spring returns to its original position, and the reel rotates in the opposite direction, retracting the cable. The user's pulling and returning motion, combined with the sliding of the seat, mimics rowing motions. Current technology typically uses single or double rope mechanisms. However, in special situations requiring three or more ropes, this is unusable, limiting its application. Alternatively, multiple single or double rope mechanisms may be necessary, leading to complexity and inconvenience in installation. Utility Model Content

When applied to corresponding fitness equipment, it can provide a multi-rope structure, which has the characteristics of simple structure, low manufacturing cost and good use effect, and is compact in structure and occupies little space.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a multi-rope mechanism for a fitness device, comprising three or more sets of take-up coils and a take-up coil fixing shaft; each set of take-up coils is respectively connected to the take-up coil fixing shaft; each take-up coil assembly includes a pull coil and a spiral spring disc, and the pull coil and the spiral spring disc are connected as one unit; the pull coil is connected to the take-up coil fixing shaft through a bearing; the spiral spring disc is provided with a spiral spring mounting groove, one end of the spiral spring is fixed to the spiral spring disc, and the other end is fixed to the take-up coil fixing shaft; a damping mechanism is installed at one end of the take-up coil fixing shaft, so that the three or more sets of take-up coils can be used to cooperate with the damping mechanism.

[0005] The multi-rope mechanism also includes a bracket, on which the take-up coil is mounted.

[0006] The bracket is also fixedly mounted with a second rotating shaft, on which are mounted the same number of rotating wheels as the take-up coils. A first belt, also in the same number as the take-up coils, connects each take-up coil assembly to its corresponding rotating wheel. The rotating wheels are connected to the second rotating shaft via a one-way bearing. A pulley is mounted on one end of the second rotating shaft corresponding to one end of the take-up coil fixed shaft. The damping mechanism also includes a rotating wheel, which is mounted on one end of the take-up coil fixed shaft or on the outside of one end of the take-up coil fixed shaft. The pulley and the rotating wheel are connected by a second belt drive.

[0007] The damping mechanism is a combination of an aluminum wheel and its matching magnetic plate.

[0008] The damping mechanism is an external magnetically controlled inertial wheel or an internal magnetically controlled inertial wheel.

[0009] The damping mechanism is a motor or a clutch.

[0010] It also includes a generator, which is fixed on the bracket and linked with the rotating wheel.
