Problems solved by technology
However, the above-mentioned structure has the following disadvantages during use: First, the fit gap between the parts is large, and the movement resistance adjustment is uneven. When the adjustment is started, the resistance adjustment is not obvious due to the large gap. The tension of spring 13 is constantly changing, and the adjustment resistance is not very obvious
The second is that the exercise arm is long, the swing range is large, and the concentricity is poor. When the exercise bike is in motion, the shaking and vibration range are large and the stability is poor.
For this reason, many manufacturers and people of insight have all carried out development and research, but do not have ideal product to come out so far

The invention discloses a resistance adjusting device of a body-building vehicle. The device comprises a base (1), a balancing wheel support (2), left and right cranks (3), a balancing wheel (4), a brake belt (5) and a resistance adjusting support (11); the balancing wheel (4) is arranged on the balancing wheel support (2) through the left and right cranks (3); the brake belt (5) is sleeved on the balancing wheel (4); each of two sides of the resistance adjusting support (11) is provided with a horizontal guide notch (8); two end joints of the brake belt (5) are fixed by inner and outer clamping sheets (6 and 7); each of the inner and outer clamping sheets (6 and 7) is provided with a raised hanging lug; the inner and outer clamping sheets (6 and 7) are arranged on the horizontal guide notches (8) through the raised hanging lugs; a rotating screw (9) is arranged on the resistance adjusting support (11); and the screw (9) is in threaded fit and connection with threaded holes of the inner and outer clamping sheets (6 and 7). By adopting the structure, the resistance structure is adjusted according to the principle that two sides of a circumference are tangential to converge at a point; and the device has the characteristics of simple and reasonable structure, convenience in operation and use, obvious frictional resistance adjustment, stable motion, long service life and the like.
Description
technical field [0001] The invention relates to an exercise bike, in particular to a resistance adjustment device for adjusting the rotational resistance of the ribbon exercise bike. Background technique [0002] With the development of society and the progress of science and technology, the pressure of work is increasing, social entertainment is increasing, and the way of travel is gradually replaced by modern means of transportation. There are many modern diseases, which not only affect the personal image, but also increase the burden on the cardiopulmonary function, resulting in many cardiovascular diseases. Therefore many sports fitness equipments adapting to modern work and life characteristics arise at the historic moment, such as exercise bikes are exactly one of them, so that busy people can carry out fitness exercises in the time and space they have to achieve the effect of motion. [0003] In order to adapt to the needs of different physiques and different loads, ...
