Most of the common rope-drawing fitness machines are installed on large-scale comprehensive fitness machines. It is to wind the rope around the pulley block and then pull the counterweight. The gravity of the counterweight generates resistance to achieve exercise when pulling the rope. effect.

However, when the user exerts force to pull the pull rope to the limit, the user needs to gradually reduce the applied force until it is less than the gravity of the counterweight, so that the counterweight will fall down and pull the pull rope back. During the recovery stroke, the user still needs to exert considerable strength against the falling weight of the counterweight, otherwise, the acceleration generated by the falling of the counterweight under the force of gravity may cause the user to be strained; especially for beginners Speaking, it is also possible that in the process of pulling the rope, due to exhaustion, it is impossible to exert force against the gravity of the counterweight, resulting in being injured by the acceleration of gravity when the counterweight falls, so it is necessary to improve.

Some simple drawstring fitness machines are made of elastic material, and the elastic force of the elastic drawcord resists the force exerted by the user, so as to achieve the effect of exercise.

It should be known that the elastic pull cord needs to have considerable elasticity to produce a good exercise effect. The stronger the elasticity, the better the exercise effect. However, the stronger the elasticity, the greater the pulling force. After force stretching the stay rope, still need to exert considerable power to stop the elastic force of the elastic stay rope pull back, if the force is improperly applied, the problem of sports injury will also be caused, so it is also necessary to improve it.

5. Specific implementation methods:

Please refer to Fig. 1 to Fig. 6, the utility model has a body 1, a pedal 11 is extended on both sides of the body 1, and each pedal 11 has a gripping portion 12 at the end far away from the body 1, and the body 1 has a two-axis 16. Each pivot is provided with a sheave 13, and each sheave 13 is respectively provided with a pull cord 14 around, and each sheave 13 has a concave accommodating space 131 for setting a volute spring 15 respectively. Each volute spring 15 has an outer end 151 and an inner end 152 respectively. The outer end 151 is hooked to the sheave 13, and the inner end 152 is hooked to a pin passing through the body 1 near the shaft 16. 17, each shaft 16 is connected with a one-way mechanism 18 respectively. In this embodiment, the one-way mechanism 18 is a one-way bearing 18, and each one-way bearing 18 drives a resistance mechanism in one direction during the rotation of the pulley 13 driven by the pull cord 14. In this embodiment, the resistance Mechanism is to adopt a friction wheel 19.

The body 1 is provided with a friction adjustment device 2 corresponding to each friction wheel 19. The friction adjustment device 2 has a friction belt 21 wound around the outer edge of the two friction wheels 19. Both ends of the friction belt 21 are fixed on a Movable seat 22, the movable seat 22 is sheathed on a slider 23, the slider 23 has two protrusions 231 to be respectively embedded in the chute 101 of the body 1, the slider 23 is connected with an adjusting bolt 24 Twist lock, and a spring 25 is provided between the slider 23 and the movable seat 22, and the slider 23 is driven to move by turning the adjusting bolt 24, so as to push the spring 25 against the movable seat 22 to change the movable seat 22. Pull the friction belt 21 against the force of the two friction wheels 19 to adjust and change the friction resistance of the two friction wheels 19 .
