The specific embodiment
At first, see also shown in Fig. 3,4, loading adjusting device of the present utility model, the instrument 3 that comprises a loading device 2 that is connected with the drawing dragline 12 of fitness equipment and a control and adjustment loading resistance constitutes, because loading device 2 has been assembled into form shown in Figure 4, very convenient when therefore being connected use with fitness equipment M, and the fitness equipment M that Fig. 3 discloses only is wherein a kind of, as long as the fitness equipment of drawing dragline 12 is in fact arranged, the utility model is all applicable.
Please consult Fig. 5 and shown in Figure 6 again, this loading device 2 consists predominantly of:
One base 21,
One support body 22 is to be installed on the base 21, and it is made of two plate bodys 221;
One magnetic conduction wheel 23 by a back shaft 231 and several bearings 232, stays in 221 of two plate bodys surely, and these back shaft 231 1 ends bearing block 222 that is set in plate body 221 that stretches through, and connects a small belt pulley 24 in the end.Again, this magnetic conduction wheel 23 and 231 of back shafts are provided with a unilateral bearing 233, make small belt pulley 24 only can take turns 23 by the unidirectional drive magnetic conduction; Described magnetic conduction wheel 23 is to be provided with one deck magnetic conductive metal 230 in the wheel body outer peripheral edges to constitute.
One capstan winch 25 is located at 26 of two support bodys by a locating shaft 251, and this capstan winch 25 comprises that one has the inboard stator 253 of fixed cover 252, is locked in locating shaft 251 by a screw 254; One outside rotating disk body 255 is hollow disk bodies of end opening in being, and its side forms axle sleeve 256, rotate on the locating shaft 251 and be set in, and disk body is provided with flange surface 257, makes 253 of itself and inboard stators form spiral groove 258, can reel on it for a cable wire 27.Again, axle sleeve 256 outer ends of disk body 255 connect a big belt pulley 28, take turns 23 side small belt pulleys, 24 interlocks by a belt 281 with magnetic conduction; One volute spring 29 is to be contained in the disk body 255, and as shown in Figure 7, its outer end 291 is fixed on disk body 255 inner edge surfaces, and the inner 292 is fixed on the fixed hub 252 of inboard stator 253.
One iron-core coil 220 is outer circumference surfaces of being located at support body 22 and pressing close to magnetic conduction wheel 23, and provides the eddy current magnetic resistance of subscription rate to it;
One shell 20 is to be located on the base 21 for aforementioned each element ccontainingly in it, and its shell face is provided with a perforation 201, can pass for cable wire 27, and be provided with the draw ring 271 that is connected with dragline 12; Location usefulness made on its locating piece 202 that is resisted against perforation 201 peripheries when this draw ring 271 can supply cable wire 27 backrush simultaneously.
As shown in Figure 3, this instrument 3 is to be located at the book office of fitness equipment M, generally speaking, be to be located at user's handled easily place, as shown in Figure 8, this instrument 3 is connected with a power-supply unit 4, and this power-supply unit 4 utilizes a transformer 41 to convert alternating current input power supplying AC to dc source, and obtains a stable dc power supply behind loop of voltage regulation 42.And instrument 3 can be controlled certain current loop 31, makes it provide predetermined dc source to aforementioned iron-core coil 220, and therefore, shown in Fig. 5,6, this iron-core coil 220 produces a vortex flow (eddy current), and then magnetic conduction wheel 23 is caused a kind of magnetoresistance.And this kind " eddy current magnetic resistance " is different with the magnetic resistance that a permanent magnet is produced, and it has enough skid resistances, and the big I of its magnetic resistance controls adjustment by instrument 3, to reach the effect of the stable and accuracy of controlled motion load.
Again, what must emphasize is, this magnetic conduction is taken turns big belt pulley 28 several times of the small belt pulley 24 of 23 sides less than capstan winch 25 sides, thus, when cable wire 27 drawstring capstan winches 25 and when making big belt pulley 28 rotate a circle, this small belt pulley 24 can drive magnetic conduction wheel 23 and rotate a few, thus, 220 pairs of magnetic conduction wheels of iron-core coil, the 23 eddy current magnetic resistance that provide are comparatively stable and accurate, and drive small belt pulley 24 with big belt pulley 28 during initial motion, it is less that magnetic conduction is taken turns 23 relative torques, is difficult for causing cable wire 27 to draw motionless situation.
In addition, as shown in Figure 7, be the volute spring 29 of being located at capstan winch 25 inside cable wire 27 by on when drawing, inboard stator 253 is motionless, and only outside rotating disk body 255 rotates with cable wire 27, and a load resistance of crispaturaing also is provided, when cable wire 27 is decontroled, then, the rotating disk body 255 of capstan winch 25 is reversed smoothly, and then cable wire 27 is recovered in the spiral groove 258 by the reverse elastic force of volute spring 29.
And as shown in Figure 6, when 255 counter-rotatings of outside rotating disk body, large and small belt pulley 28,24, belt 281 and back shaft 231 reverse simultaneously, but because of the unilateral bearing 233 of back shaft 231 does not drive magnetic conduction wheel 23 when reversing, so can not form interference, running can provide a stable motion loading so continuously.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
In sum, the utility model is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
