The utility model content
Technical problem to be solved in the utility model is, provides the resistance of motion is remained unchanged for a long time, makes the predetermined resistance of motion can not produce a kind of drag regulator of error.
For solving the problems of the technologies described above, a kind of drag regulator that the utility model provides, it comprises support, rotatable friction member is installed on the support, one end of friction member is connected with weighting distribution wheel, an end face of the close support of described weighting distribution wheel is provided with annular groove, the perisporium of annular groove increases gradually from the bottom to opening diameter, the opening part of annular groove is provided with the aluminium circle, on the described support magnet holder is installed, magnet holder is between support and aluminium circle, magnet holder is provided with near the perisporium of annular groove and the magnetic receiver that can move along the radial direction of perisporium, magnet is installed on the magnetic receiver, and magnetic receiver is connected with the governor motion that can make magnetic receiver move and lock.
Operation principle of the present utility model is as follows: the wheel of bicycle is placed on the friction member, wheel can drive the friction member rotation during cycling, that is to say that friction member can provide the resistance of motion to wheel, and friction member is connected with weighting distribution wheel, when needs increase the resistance of motion, the moving magnet seat, it is outwards mobile along the radial direction of the perisporium of annular groove to make magnetic receiver drive magnet, the distance of perisporium that is to say this moment magnet and annular groove is more and more nearer, it is increasing that this moment, weighting distribution wheel was subjected to the magneticaction of magnet, thereby the resistance of motion of weighting distribution wheel is increased gradually, thereby the resistance of motion of friction member is increased gradually, and resistance increases gradually when making the wheel movement of bicycle, otherwise, if reduce the resistance of motion, as long as the distance of the perisporium of magnet and annular groove is increased, the magneticaction that this moment, weighting distribution wheel was subjected to magnet reduces, thereby the resistance of motion of weighting distribution wheel is reduced, thereby the resistance of motion of friction member is reduced, and resistance reduces when making the wheel movement of bicycle.
After adopting above structure, the utility model compared with prior art has following advantage:
Because the adjusting of resistance is by changing the magneticaction that weighting distribution wheel is subjected to, the bicycle prolonged exercise can not change variation of magnetic force, thereby can not change the resistance of motion of weighting distribution wheel owing to the bicycle prolonged exercise, the resistance of motion can be remained unchanged for a long time, make the predetermined resistance of motion can not produce error.
As improvement, described magnet holder is provided with the fin that extends along the radial direction of the perisporium of annular groove, and magnetic receiver is provided with the gathering sill that cooperates with fin; Guide effect is played in the cooperation of gathering sill and fin, can guarantee that magnetic receiver moves along the radial direction of the perisporium of annular groove.
As improvement, described governor motion comprises the adjusting line, adjustment seat and adjustment seat panel, adjustment seat and adjustment seat panel are interlocked, be provided with adjusting knob between adjustment seat and the adjustment seat panel, two retainer springs and two locking balls, adjusting knob is connected with the regulating handle that the controllable adjustable button moves, the bottom surface of adjusting knob is provided with several detents spaced apart, one end of two retainer springs is all fixed in adjustment seat, the other end of two retainer springs offsets with a side of two locking balls respectively, the opposite side of two locking balls all matches with several detents, an end of regulating line is connected with adjusting knob, and the other end of regulating line is connected with magnetic receiver; Driving magnetic receiver by regulating handle moves, thereby change the distance of the perisporium of magnet and annular groove, thereby change the magnetic field power, whenever driving adjusting knob, regulating handle moves certain distance, locking ball will snap in the corresponding detent, make adjusting knob locked, the displacement of adjusting knob can better be controlled, the displacement of magnetic receiver can better be controlled, make that the distance of perisporium of magnet and annular groove can better be controlled, the magnetic field power can better be controlled, thereby the resistance of motion can better be controlled.
