Problems solved by technology
In the process of use, the adjustment of the resistance is to change the number of counterweight iron blocks of the traction unit through the manual plug. The weight of a unit counterweight iron block is generally 2.5kg or 5kg, that is to say, each time the traction resistance is adjusted is the weight of the unit counterweight iron block. It cannot be adjusted to any resistance value, and manual pin adjustment is inconvenient to use, which may easily lead to mechanical failure

The invention discloses a linear adjusting device for resistance of power equipment. The linear adjusting device for the resistance of the power equipment comprises a bottom rack, and further comprises a track bed mounted on the bottom rack, and a driving device; one end of the track bed is connected with the bottom rack through a hinge pin, so that the track bed can vertically overturn along thehinge pin; a track and a trolley which is in sliding fit with the track are arranged on the track bed in the extension direction of the track bed; balancing weights and a pull rope for pulling the trolley to slide on the track are fixed on the trolley; and the driving device is used for driving the track bed to turn vertically. In a climbing process of the trolley, the resistance of a pull rope isactually a result which is the sum of the gravity of the balancing weights and the gravity of the trolley through the Pythagorean Theorem. Because the gravity is certain and the resistance is in direct proportion to the angle, the resistance can be linearly adjusted by adjusting the magnitude of the angle. In addition, an adjustment range can be expanded by increasing and reducing the number of balancing weights.
Description
technical field [0001] The invention relates to a device for adjusting resistance in fitness equipment for strength training. Background technique [0002] The resistance device of the existing fitness strength equipment is realized by pulling the counterweight. The counterweight is superimposed up and down by multiple unit counterweight iron blocks. The size of the traction resistance is adjusted by changing the weight of the counterweight, increasing or decreasing different The quantity of unit counterweight iron blocks is used to realize the change of counterweight weight. The more unit iron blocks towed at one time, the greater the resistance, and vice versa. In the process of use, the adjustment of the resistance is to change the number of counterweight iron blocks of the traction unit through the manual plug. The weight of a unit counterweight iron block is generally 2.5kg or 5kg, that is to say, each time the traction resistance is adjusted is the weight of the unit c...
