Description
Technical field
The invention relates to a kind of exercise car, particularly a kind of resistance adjustment device that is used for regulating the rotary resistance of ribbon exercycle.
Background technology
Along with social development and scientific and technological progress, operating pressure is increasing, 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 declines, many modern diseases have been brought thereupon, this not only affects personal image, and can increase the burden of cardio-pulmonary function, derives many angiocardiopathies.Therefore the exercise and fitness equipment of the modern work of various adaptability and life characteristic arises at the historic moment, and if exercycle is exactly wherein a kind of, makes busy people can carry out the effect that body-building exercise reaches motion in the time having had and space.
In order to adapt to different physique and unequally loaded needs, exercycle is all provided with resistance adjustment device, as shown in Figure 4, it 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 crank 3, weighting distribution wheel 4, brake ribbon 5, resistance regulates support 11, screw rod 9, regulating arm 12, extension spring 13, weighting distribution wheel support 2 regulates support 11 to be fixedly connected with base 1 with resistance, weighting distribution wheel 4 is fixed on left and right crank 3, left and right crank 3 is arranged on weighting distribution wheel support 2 rotationally, regulating arm 12 is hinged on resistance and regulates on support 11, brake ribbon 5 is set in the peripheral groove of weighting distribution wheel 4, one end of brake ribbon 5 is fixed on base 1 by holder 14, the other end of brake ribbon 5 is connected on regulating arm 12 by 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 by extension spring 13, weighting distribution wheel 4 spin friction power is increased, thereby reach the object that regulates spinning resistance; Otherwise can reduce spinning resistance.But said structure in use has the following disadvantages: the one, and between each parts, fit clearance is large, the resistance of motion regulates inhomogeneous, while starting to regulate because gap is large, resistance regulates not obvious, when continuing adjustment movement resistance, because the pulling force of extension spring 13 constantly changes, regulating resistance is not clearly.The 2nd, motoricity brachium, amplitude of fluctuation is large, and concentricity is poor, rocks and Oscillation Amplitude is large, stationarity is poor during spinning.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have so far desirable product to emerge.
Summary of the invention
For overcoming the existing above-mentioned deficiency of existing exercycle resistance adjustment device, the object of the invention be to 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 adopted technical scheme, it comprises base, weighting distribution wheel support, left and right crank, weighting distribution wheel, brake ribbon, resistance regulates support, weighting distribution wheel support regulates support to be fixedly connected with base with resistance, weighting distribution wheel is fixed on the crank of left and right, left and right crank is arranged on weighting distribution wheel support rotationally, brake ribbon is set in the peripheral groove of weighting distribution wheel, described resistance regulates the both sides of support to be provided with symmetrical horizontally-guided notch, two end connector tangential directions of brake ribbon are fixedly connected with by inside and outside clamp clip after drawing and converging a bit, inside and outside clamp clip is provided with the protruding hangers matching with horizontally-guided notch, inside and outside clamp clip is arranged on horizontally-guided notch movably by protruding hangers, resistance regulates support to be provided with screw rod rotationally, screw rod is connected on the screwed hole of inside and outside clamp clip by threaded engagement.
The further scheme of the invention, the described inside and outside screwed hole of clamp clip and the center of circle of screw rod center line and weighting distribution wheel are in the same horizontal line.
The further scheme of the invention, described screw rod is arranged on resistance by positioning sleeve and regulates on support.
Adopt after said structure, have the following advantages compared with the prior art and effect.
The one, the utility model adopts that circumference both sides are tangent converges some principles and regulate resistance structure, two end connector tangential directions of brake ribbon are fixed by inside and outside clamp clip after drawing and converging a bit, inside and outside clamp clip is arranged on guiding slot port by protruding hangers movably, when rotating screw bolt, screw rod drives inside and outside clamp clip to move horizontally on guiding slot port, so, compact conformation between each parts, fit clearance is little, the two ends of brake ribbon are stressed evenly, resistance is easy to adjust, stable, in motion process, regulate change in resistance obvious, light phenomenon when heavy while there will not be, even can lock motionless state, can regulate easily the resistance of motion of exercycle, the movement effects that adapts to different physique body builders.
The 2nd, because screw rod directly drives brake ribbon by inside and outside clamp clip, the circle centre position of screw rod center line and weighting distribution wheel in the same horizontal line, weighting distribution wheel stability under loading, good concentricity, 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, there are wide market prospects.
