Detailed Description

The embodiment of the utility model provides a rope pulling body builder which comprises a shell 1, wherein a rotatable rope wheel 2 is arranged in the shell 1; a pull rope 3 is wound on the rope wheel 2; one end of the pull rope 3 extends out of the shell 1; an air bag 4 arranged corresponding to an external fixing structure is connected to the outer side of the shell 1, and an inflating mechanism communicated with the air bag 4 is arranged on the shell 1; the inflation mechanism inflates the air bag 4 to expand the air bag 4 so as to be clamped on the fixing structure, so that the shell 1 is fixed relative to the fixing structure during stretching exercise. This 3 fitness equipments of stay cord are equipped with air pocket 4, make 4 fixed 3 fitness equipments of this stay cord of joint on fixed knot structures such as crack after the inflation of air pocket, the user stimulates stay cord 3 and just can take exercise convenient to use.

One end of the air bag 4 is locked on the shell 1, and the other end can be attached to the shell 1 through a magnetic buckle. When not in use, the air bag 4 is attached to the shell 1 through a magnetic buckle so as to be convenient to store.

A coil spring 5 is arranged in the shell 1; one end of the coil spring 5 is clamped with the rope wheel 2, and the other end is clamped with the shell 1, so that elastic resistance is provided for the rotation of the rope wheel 2 relative to the shell 1, and a user can receive the elastic resistance when pulling the pull rope 3 to achieve the exercise effect.

A rotatable counterweight wheel 6 is arranged in the shell 1; the balance weight wheel 6 is coupled to the sheave 2 to rotate with the sheave 2. The weight wheel 6 increases the resistance which the user needs to overcome to pull the pull rope 3 during exercise, thereby enhancing the exercise effect.

The sheave 2 and the balance weight 6 are coupled by a planetary gear mechanism 7.

A resistance adjusting device 8 is arranged in the shell 1; the resistance adjusting device 8 comprises a mounting bracket 9 and a magnet 10; the mounting bracket 9 is fixed in the casing 1, and the magnet 10 is arranged on the mounting bracket 9 and can slide in the mounting bracket 9 so as to control the magnetic resistance of the weight wheel 6 by changing the distance from the weight wheel 6. The resistance adjusting device 8 further comprises a rotating disc 11 and a sliding base 12; a chute is arranged in the mounting bracket 9; the sliding base 12 is arranged in the sliding chute; the magnet 10 is fixed on the sliding base 12; the rotary table 11 is rotatably arranged on the mounting bracket 9 and is connected with and controls the sliding base 12; the rotating disc 11 is rotated to make the sliding base 12 drive the magnet 10 to slide in the chute, so as to change the magnetic resistance received by the counterweight wheel. The resistance adjusting device 8 adjusts the resistance of the pull rope 3 when a user exercises by changing the magnetic resistance of the counterweight wheel 6, and the user can set a proper resistance value according to the self condition

A display screen 13 is arranged outside the shell 1; a sensor 14 is arranged in the shell 1 and used for detecting the rotating angle of the balance weight wheel and calculating the pulled-out length of the pull rope 3, and the pulled-out length of the pull rope 3 is transmitted to the display screen 13 to be displayed.
