Fitness equipment concentric circle magnetic control transmission system

technical field

The utility model relates to a concentric circle magnetic force control transmission system device for fitness equipment.

Background technique

At present, sports equipment has different functional forms and models depending on the different parts of the desired exercise and fitness, and among the sports and fitness equipment related to the pedal exercise function, there are many types of sports and fitness equipment that utilizes magnetic force to control the power of the pedals, and it is impossible to list them one by one. To repeat and compare, however, no matter what type of magnetic control pedal exerciser is all using a rotating disc and a belt to drive the counterweight disc to rotate, if the speed ratio of the rotating disc and the counterweight disc is to be increased, then It is necessary to increase the size of the rotating disk, so that the overall size and area will be increased, which will result in increased cost and inconvenience in assembly.

Utility model content

The purpose of this utility model is to provide a concentric circle magnetic control transmission system for fitness equipment, which is composed of a main frame, a shaft, a fixed belt pulley, a movable belt pulley, a belt and a counterweight plate, and the shaft is inserted through the The shaft holes of the fixed belt pulley and the counterweight plate are pivotally connected with the pedal rod through the hole on the bracket. The discs are pivotally connected, and the belts are respectively placed between the fixed and movable belt discs and the belt grooves between the counterweight discs and the first and second belt grooves. When the transmission is performed, the pedal rod drives the shaft to rotate, so that the shaft is The connecting rod is driven accordingly, and because the supporting shafts at the end of the connecting rod are pivotally connected to the movable belt pulley, therefore, when the connecting rod is rotated by the rotation of the shaft, the movable belt pulley is synchronized with the connecting rod for revolution and rotation, and Since the movable belt pulley is pivotally connected to the support shaft at the end of the shaft link, and the belt is affected by the positioning tension of the fixed pulley pulley, and the belt is respectively placed between the fixed pulley pulley, each movable pulley pulley and the counterweight plate. Therefore, when the movable pulley rotates in revolution, it also rotates synchronously. Because the belt groove between the fixed and movable pulleys and the counterweight is connected to the first and second pulleys The belts set between the belt grooves and the relationship between them can increase the inertia of the counterweight plate’s rotational speed, and use the principle of concentric circle transmission to increase the speed ratio to the counterweight plate without increasing the size of the movable belt plate. The overall size and area are effectively reduced, the overall weight is reduced, assembly is facilitated, and the overall cost is reduced at the same time.

The secondary purpose of this utility model is to provide a concentric circle magnetic force control transmission system for fitness equipment, in which, in order to further increase the speed inertia of the counterweight plate, the number of movable belt pulleys can be increased as required, and the number of movable pulley pulleys can be adjusted to match the number of active belt pulleys. Added, multi-link and multi-support shafts can be designed at the same time to cooperate with use.

The technical scheme provided by the utility model is:

A concentric circle magnetic control transmission system for fitness equipment is mainly composed of a main frame, a shaft rod, a fixed belt pulley, at least one movable belt pulley, at least one belt and a counterweight plate. The main frame is provided with a hole , a number of locking holes are opened around the hole, a connecting rod is extended on the shaft, and a supporting shaft is extended at the end of the connecting rod.
