Description

  The present invention belongs to a technical field of a kind of health appliance, and particularly relates to a structure of a health appliance having a wind sound effect, in addition to being able to increase the damper action of the magnetically controlled damper when using the health appliance.

  With the improvement of industrial technology, in the field of healthy exercise equipment, various health equipments provide users with exercise effects for each part of the body in different ways. In addition, various ingenuity has been devised in terms of functions, such as improving the effect of damper load during use and adding functions such as the generation of sound effects of windmill wind noise.

  FIG. 1 shows a technique described in Patent Document 1, in which a winder 82 and a damper ring 83 are provided in a rowing health device 81 using a frame, and the winder 82 and the damper ring are provided. 83 is coupled by a belt 84 so as to be interlocked. The feature is that a plurality of resistance pieces 85 are spaced from each other on the circumferential surface of the damper ring 83, and the installation of these resistance pieces 85 generates wind resistance in the process of rotating the damper ring 83, thereby increasing the damper effect. There is.

This well-known health appliance can increase the damper function in use, but in fact its structural design is poor, the cost of manufacturing and processing increases, and the effect of wind resistance is effectively and reliably demonstrated. There is no need for improvement. The shortcomings of the structure are summarized as follows.
1. The processing and assembly structure is defective. In view of the above, in this known structure, a plurality of resistance pieces 85 are fixed to the ring circumferential surface of the damper ring 83 with screws, and thereby a screw hole corresponding to the ring circumferential surface of the damper ring 83 must be formed. In other words, the burden on manufacturing and processing increases. Further, it takes time and labor to attach the resistance pieces 85 to the damper wheel 83 one by one. In addition, the angle, height position, and tightening degree of each resistance piece 85 attached to the damper ring 83 are not completely matched, so that slack occurs during use and the effect of wind resistance is affected.
2. The effect of wind resistance is not clear. In the well-known invention, a resistance piece 85 used for generating wind resistance and exhaust function is attached to the circumferential surface of the damper ring 83, and as the damper ring 83 rotates, these resistance pieces 85 are used as shown in FIG. The rotation path position at which 85 rotates to generate the wind resistance function is superimposed on the outer diameter of the damper wheel 83. Although it seems that there is no defect in the use of such a structure in general concept, actually, the bottom end of the resistance piece 85 abuts on the outer diameter of the damper ring 83 and the top end of the resistance piece 85 or Both side surfaces only have the action of pushing air outwardly under the rotational centrifugal force and the guiding action of the resistance piece 85. Under high speed rotation, both side ends of the resistance piece 85 thereby become the “wind wall”. A similar phenomenon is formed, and the gas outside the resistor piece 85 cannot effectively enter between the adjacent resistor pieces 85, and the effect of wind resistance cannot be formed effectively.

  In the present invention, there is no blade design between the blade and the impeller shaft center, and the gas is easily generated by the centrifugal force action generated by the impeller and the effect of the air flow and the pressure difference generated by the radial blade. It can be introduced between the blades from the central space to achieve the effect of wind resistance.

  As shown in FIGS. 3 and 4, the magnetically controlled ring blade device of the present invention includes a winding wheel 20 and a magnetically controlled wheel 30 that are pivotally connected to a health appliance frame (not shown) and coupled in an interlocking manner. In addition, the damping effect generated by the magnetic control wheel 30 provides the user with a resistance effect when exercising. Among them, the health appliance frame is not limited to a specific model.

  That is, the health device frame has a general machine frame structure, and a winding wheel 20 and a magnetic control wheel 30 are pivoted so as to be adjacent to each other, and a woven belt 51 is wound around the winding wheel 20 so that the magnetic An impeller 40 is fixed to the control wheel 30.

  A unidirectional bearing (not shown) is provided in the winding wheel 20, which is a ring-shaped part that performs a unidirectional rotary winding operation, and a winding portion 21 that winds and fixes one end of the woven belt 51 around the ring shaft. In addition, an annular portion 22 is installed so as to be adjacent to the winding portion 21. One end of the transmission band 52 is fitted to the ring zone portion 22, and the other end of the transmission band 52 is fitted to a corresponding position of the magnetic control wheel 30.
