A comprehensive fitness device capable of steplessly adjusting resistance

Abstract

A comprehensive body-building device disclosed by the present invention, which can steplessly adjust the resistance, is characterized in that it includes a frame, on which a gravity assembly for adjusting gravity is mounted slidingly, and the gravity assembly is provided with a stepless resistance Control device; the resistance stepless control device includes a motor, a reducer, a driving wheel, and a driven ring set on the driving wheel. The outer wall of the driving wheel and the inner wall of the inner hole of the driven ring are respectively provided with elastic protrusions and fixed protrusions , the driving wheel is fixedly connected with the rotating part of the reducer, and the traction rope is wound on the driven ring, among which, the current input to the motor is controlled to realize the stepless adjustment of the motor torque, so as to steplessly adjust the resistance of the traction rope when it is pulled. control, and the elastic protrusions and the fixed protrusions are in a mutual blocking state, so that after the driving wheel or the driven ring sleeve rotates, the elastic protrusions and the fixed protrusions contact each other to generate friction and extrusion force. It can steplessly adjust the resistance of fitness equipment, and provide fitness protection for people during exercise.

Description

technical field [0001] The invention relates to the technical field of fitness equipment with a stepless weight adjustment function, in particular to a comprehensive fitness device capable of steplessly adjusting resistance. Background technique [0002] The resistance devices used in current fitness equipment use heavy blocks to adjust the weight through volume changes, and the gravity of the weight blocks only adjusts the resistance by clamping a certain volume change. The resistance change level is limited and cannot be accurate. It is suitable for everyone, but the user can only use a constant resistance when exercising. In fact, the user needs to change the force during the exercise to achieve the greatest exercise effect. The resistance source is used to realize the stepless adjustment of resistance. For example, the patent number announcement is CN211132850U, a kind of strength fitness equipment. However, this type of strength fitness equipment is easy to be suddenly ...

[0002] The resistance devices used in current fitness equipment use heavy blocks to adjust the weight through volume changes, and the gravity of the weight blocks only adjusts the resistance by clamping a certain volume change. The resistance change level is limited and cannot be accurate. It is suitable for everyone, but the user can only use a constant resistance when exercising. In fact, the user needs to change the force during the exercise to achieve the greatest exercise effect. The resistance source is used to realize the stepless adjustment of resistance. For example, the patent number announcement is CN211132850U, a kind of strength fitness equipment. However, this type of strength fitness equipment is easy to be suddenly stuck in the motor, so that the body cannot counteract the inertia of motion and cause great damage to the muscles. , so the security cannot be guaranteed
