Abstract

The utility model is an improved structure of boating apparatus, consisting of a base 10, a transmission group 20, a ratchet group 30, a magnetically controlled braking device 40, a fan 50 and so on; the device is characterized in that the ratchet group includes a front large ratchet arranged on one side of the rope pulley, a back small ratchet pivoted at the back of the rope wheel through the belt, a back large ratchet driven and pivoted on one side of the rod coaxial with the back small ratchet, an upper large ratchet coaxially connected and pivoted with the fan through another belt; the magnetically controlled braking device includes a flywheel pivoted on the fan corresponding to the other side of the upper small ratchet, a magnet seat whose shaft is pivoted on the positioning place on the side plate on the upper end of the positioning plate, an adjusting button automatically positioned on the side end of the arc-shaped frame by the steel cable and passing through the positioning plate; the final edge is fixed and arranged on the bottom of the magnet base; with the assembly of the above components, the rope can synchronously drive the ratchet wheel when being pulled, to make the flywheel have a quicker rotating speed and to provide a relatively large inner capacity; the magnetically controlled braking device can not only interfere the magnetic field produced by the flywheel, but also has no influence on the smoothness of the rotation of the flywheel.

Description

The structural improvement of paddle exerciser

Technical field

The utility model relates to mechanical, and particularly a kind of structural improvement of paddle exerciser refers to a kind of fan wheel and magnetic control brake apparatus of being combined with especially in one, and utilization ratchet group interlock, advances so that during the start of ratchet group, can make fan wheel produce bigger rotating speed.

Background technology

As everyone knows, common rowing machine structure, mainly be on the pedestal of rowing machine, to be provided with pedal and seat, step on for user's seat, and in the cabinet rake of pedestal end, be provided with a cable pulley, fan, utilize a belt sleeve around between the axle center and Fan axial center of reverse cable pulley, form unidirectional interlock, when the user spurs handle, can spur the stay cord on the cable pulley, make mat belt transmission fan and produce windage, and make handle return back to original position by returning spring, spur handle repeatedly for the user, reach the purpose of motion; Peripheral ring is provided with a rotating disc in the axle center of rowing machine fan, then is provided with a copper sheet on this rotating disc; Be installed with a magnetic control group on the hack lever that approaches the fan attachment axle center, this magnetic control group is that a positioning seat, is provided with the magnetic receiver of permanent magnet and cooperates cable wire to link a resistance regulator and constitutes; Wherein this positioning seat is to offer an elongated slot in central authorities, this magnetic receiver is to make semilune, and be installed with a cable encasing-tube in the elongated slot both sides or adjust the screw group, cable wire stretches through out, each end of cable wire is consolidated on the lock ear of magnetic receiver, the cable wire that cable encasing-tube extends outward end in addition then links with resistance regulator, and constitutes a circulation loop; So, when rotating resistance regulator, the interlock of mat cable wire and spur magnetic receiver makes permanent magnet controlled by displacement, and its magnetic line of force that acts on copper sheet is changed, and impels rowing machine to obtain different resistances and reaches preferable movement effects; Above-mentioned linkage is only walked around reversing wheel to cable pulley with a stay cord cover merely, be fixedly arranged on the big belt pulley start in cable pulley axle center with drive, after a belt links big belt pulley and the small belt pulley that is hubbed at Fan axial center, and then the transmission fan produces windage, to reach the purpose of motion, when its shortcoming is the linkage start, the rotating speed of its small belt pulley that drives is quite slow, suitable limited of the relative air quantity that fan produced, and this common rowing machine is equipped with the magnetic control group again, the rotating speed of fan is more slow when more making the overall structure start, and yes can't really supply with suitably refrigerant air quantity of sporter; In addition, the permanent magnet of its magnetic control group is at interval suitable apart from the capable magnetic effect of single side that is installed in copper sheet, and the phenomenon that can cause running to have some setbacks under the permanent running of linkage produces, and makes suitable inharmonious of whole start.

The utility model content

According to the purpose of this utility model, shortcoming at above-mentioned common rowing machine existence, a kind of structural improvement of paddle exerciser is provided, its structure is to be provided with a seat and two pedals at pedestal one end, and end is to be formed with an arc frame in addition, and is provided with a transmission group in the lower end of arc frame group, an one ratchet group and a magnetic control brake apparatus, this transmission group is to comprise that it is to be wound in a cable pulley after walking around two pulleys that handle binding has stay cord, this stay cord, and this cable pulley is provided with scroll spring in the central shaft both sides; This ratchet group is included in cable pulley one side and is provided with preceding large ratchet, and utilize belt to be linked to be hubbed at the back little ratchet of cable pulley rear end, be hubbed on the back large ratchet of little coaxial ratchet bar one side afterwards with drive, this back large ratchet is linked to the last little ratchet that is hubbed on the fan concentric with a belt in addition; This magnetic control brake apparatus includes relative another side that a flywheel is hubbed on little ratchet on the fan side; Cable pulley be pivoted the location side plate one end be connected with a location-plate; The side plate that one shape magnetic receiver is a pivot in the location-plate upper end gives decides the place, is installed with permanent magnet in shape magnetic receiver relative inner correspondence; Location-plate is passed in the self-align adjustment button binding at the arc frame side of one cable wire, and last ora terminalis then is installed in the bottom of shape magnetic receiver; Cable wire is arranged with a spring between location-plate and shape magnetic receiver; By the assembling of above-mentioned member, when the start of ratchet group, can make wind wheel produce rotating speed faster, relative provide bigger air quantity; And the permanent magnet that magnetic receiver set firmly of magnetic control brake apparatus can be organized and is located at flywheel ora terminalis both sides, not only can produce magnetic interference to flywheel, more be unlikely influence the flywheel running steadily.
