Description
Technical field
The invention relates to a kind of sport and body-building car, particularly a kind of resistance adjustment device that is used for regulating the rotary resistance of ribbon exercycle.
Background technology
Along with the development and the scientific and technological progress of society, operating pressure is increasing, and society's dinner party is more and more; Trip mode is also progressively replaced by the modern means of communication, very little free participation body building, and fitness constantly descends; Many modern diseases have been brought thereupon; This not only influences personal image, and can increase the burden of cardio-pulmonary function, derives many angiocardiopathies.The exercise and fitness equipment of modern work of therefore various adaptability and life characteristic arises at the historic moment, be exactly wherein a kind of like exercycle, makes busy people in the time that has had and space, can carry out body-building and exercises and reach the effect of motion.
In order to adapt to different physique and unequally loaded needs; Exercycle all is provided with resistance adjustment device, and is as shown in Figure 4, is exactly the comparatively general resistance adjustment device of ribbon exercycle use at present; It comprises base 1, weighting distribution wheel support 2, left and right sides crank 3, weighting distribution wheel 4, brake ribbon 5, resistance adjusting support 11, screw rod 9, regulating arm 12, extension spring 13; Weighting distribution wheel support 2 is regulated support 11 with resistance and is fixedly connected with base 1, and weighting distribution wheel 4 is fixed on the left and right sides crank 3, and left and right sides crank 3 is arranged on the weighting distribution wheel support 2 rotationally; Regulating arm 12 is hinged on resistance and regulates on the support 11; Brake ribbon 5 is set on the peripheral groove of weighting distribution wheel 4, and an end of brake ribbon 5 is fixed on the base 1 through holder 14, and the other end of brake ribbon 5 is connected on the regulating arm 12 through extension spring 13.When needs increase the resistance of motion, inside rotary screw 9, screw rod 9 pushing tow regulating arms 12, regulating arm 12 is tightened brake ribbon 5 through extension spring 13, and weighting distribution wheel 4 spin friction power are increased, thereby reaches the purpose of regulating the spinning resistance; Otherwise promptly can reduce the spinning resistance.But in use there is following weak point in said structure: the one, and fit clearance is big between each parts; The resistance of motion is regulated inhomogeneous; When beginning to regulate because gap is big, and resistance is regulated not obvious, when continuing the adjustment movement resistance; Because the pulling force of extension spring 13 constantly changes, regulating resistance is not clearly.The 2nd, the motoricity brachium, amplitude of fluctuation is big, and concentricity is poor, rocks during spinning and Oscillation Amplitude is big, stationarity is poor.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have desirable product to emerge so far.
Summary of the invention
For overcoming the existing existing above-mentioned deficiency of exercycle resistance adjustment device, the purpose of the invention provide a kind of simple and reasonable, easy for operation, frictional resistance change little, motion steadily, the exercycle resistance adjustment device of long service life.
The invention solves the problems of the technologies described above the technical scheme that is adopted; It comprises base, weighting distribution wheel support, left and right sides crank, weighting distribution wheel, brake ribbon, resistance adjusting support; The weighting distribution wheel support is regulated support with resistance and is fixedly connected with base; Weighting distribution wheel is fixed on the crank of the left and right sides, and left and right sides crank is arranged on the weighting distribution wheel support rotationally, and brake ribbon is set on the peripheral groove of weighting distribution wheel; The both sides that said resistance is regulated support are provided with symmetrical horizontally-guided notch; Two end connector tangential directions of brake ribbon are fixedly connected by inside and outside clamp clip after drawing and converging a bit, and inside and outside clamp clip is provided with the protruding hangers that matches with the horizontally-guided notch, and inside and outside clamp clip is arranged on the horizontally-guided notch through protruding hangers movably; Resistance is regulated support and is provided with screw rod rotationally, and screw rod is connected on the screwed hole of inside and outside clamp clip through threaded engagement.
The further scheme of the invention, the screwed hole of said inside and outside clamp clip and the center of circle of screw rod center line and weighting distribution wheel are on same horizontal line.
The further scheme of the invention, described screw rod is arranged on resistance through positioning sleeve and regulates on the support.
After adopting said structure, following advantage and effect are relatively arranged with prior art.
The one, the present invention adopts that the circumference both sides are tangent converges some principles and regulate resistance structure, and two end connector tangential directions of brake ribbon are drawn and converged some back and fixed by inside and outside clamp clip, and inside and outside clamp clip is arranged on the guiding slot port through protruding hangers movably; When rotating screw bolt, screw rod drives inside and outside clamp clip and on guiding slot port, moves horizontally, so; Compact conformation between each parts, fit clearance are little; The two ends of brake ribbon are stressed evenly, and resistance is easy to adjust, stable, and the adjusting change in resistance is obvious in the motion process; Light phenomenon when weighing in the time of can not occurring; Even can lock motionless state, and can regulate the resistance of motion of exercycle easily, adapt to different physique body builders' movement effects.
The 2nd because screw rod directly drives brake ribbon through inside and outside clamp clip, the circle centre position of screw rod center line and weighting distribution wheel on same horizontal line, the weighting distribution wheel stability under loading, good concentricity is so rock during spinning and Oscillation Amplitude is little, stationarity is good.
The 3rd, simple and reasonable, easy to operate, durable in use, elegant in appearance, be convenient to popularize, have vast market prospect.
