Description

Have multistage and adjust the fitness equipment adjusting device of amplitude of oscillation function

This utility model relates to a kind of fitness equipment adjusting device that multistage is adjusted amplitude of oscillation function that has, especially a kind of periphery of knob forms the rough pattern of Flos Mume head, so that it more meets the body mechanics, make operator's use more comfortable, and snap-in structure by steel ball and shrinkage pool between knob and locating shaft, make rotation can do two-way adjustment rotation, with so that the amplitude of oscillation of fitness equipment is adjusted to the adjusting device of appropriateness easily, bring certain body-building effect to user.

A kind of existing belt has the fitness equipment of amplitude of oscillation vibrating effect, its primary structure reaches shown in Figure 2 as shown in Figure 1, its fitness equipment A includes a pedestal A1, uprightly be equipped with a support A2 on the pedestal A1, the top of support A2 then is provided with a body B, its body drives a driving shaft B1 by a motor and rotates, the both sides of body B are located at the two ends of this driving shaft B1 respectively, other has diaxon piece B2 to be the both sides that eccentric form is disposed at driving shaft B1 with driving shaft B1, the outer face of axle piece B2 then is respectively equipped with the force-output shaft B3 that also is eccentric configuration with axle piece B2 axle, and the force-output shaft B3 that makes its driving shaft B1 two ends is the biasing of a special angle, other has a belt C that the link C1 at its two ends is placed in respectively on the force-output shaft B3, with when its driving shaft B1 rotates, the biasing rotate effect of its two ends force-output shaft B3 will form an effect of pullling to belt C, and make its integral body be the vibrating effect of a specific amplitude of oscillation; And be to make the amplitude of oscillation of its belt have adjustable effect, the fitness equipment that the same action principle then arranged the end face of its piece be provided with in addition one with its swivelling cover that cooperates with ratchet structure, again force-output shaft is located at the end face of swivelling cover, by rotating swivelling cover so that force-output shaft becomes the change of angle direction with driving shaft with single direction, and then make the amount of bias that changes the two ends force-output shaft and reach the effect of adjusting the amplitude of oscillation, yet the rotation of ratchet has directivity, and the operator can be used and can't really fitness equipment be adjusted to the amplitude of oscillation that is fit to self-demand because of not rotating swivelling cover smoothly in use.

The purpose of this utility model provides a kind of fitness equipment adjusting device that multistage is adjusted amplitude of oscillation function that has, its two-way rotation simultaneously, and then the amplitude of oscillation of fitness equipment is adjusted to appropriateness easily, allow user reach certain body-building purpose; And can make it more meet the body mechanics, make operator's use more comfortable.

For achieving the above object, solution of the present utility model is: originally have the fitness equipment adjusting device that multistage is adjusted amplitude of oscillation function, basic structure is made of a knob and a locating shaft, one end of its locating shaft is formed with the axis hole of an eccentric configuration, be nested with mutually with the driving shaft of body exercising machine, and wear a screw in the periphery of locating shaft and pass straight through to the axis hole place, be beneficial to lock and locating shaft is locked mutually with driving shaft by a bolt.The periphery of this knob forms the rough pattern of Flos Mume head, and be formed with the posthole that several are the certain degree configuration on composition surface with locating shaft, this locating shaft then with the binding face of knob on be formed with the shrinkage pool that is involutory with posthole, in each posthole of knob, fill in spring and steel ball in regular turn in addition, by a steel ball cover plate steel ball is limited in the posthole again, because of its steel ball cover plate is provided with mutually opposed with posthole but the aperture is slightly less than the circular hole of posthole, so its steel ball is exposed to the end face of steel ball cover plate; In addition, other has a collar cover plate, the circular hole of its center for locating shaft is worn, and locating shaft is formed with a flange in the side end face within it, can lock together with knob and steel ball cover plate that locating shaft is limited to the knob end face is the state that subsides mutually contain by collar cover plate, steel ball on the knob can be exposed by the circular hole of steel ball cover plate and with locating shaft on the shrinkage pool location that fastens; In addition, then be locked in end, the knob outside with the form of off-centre configuration equally in order to the force-output shaft that hangs belt two ends link, when rotary knob, its steel ball is striden across block other steel balls that the shrinkage pool order that contains is adjacent and fall into shrinkage pool with it, have segmentation between knob and locating shaft and rotate localized effect and make, can make with eccentric form and be assemblied in the force-output shaft on the knob and the driving shaft angle direction that is arranged on the locating shaft changes, and then make the force-output shaft with the driving shaft other end have the effect that the multistage amplitude of oscillation is adjusted.

Because this utility model has adopted the spring of posthole, posthole the inside and steel ball, steel ball cover plate, collar structure of cover plate, steel ball on the knob can be exposed by the circular hole of steel ball cover plate and with locating shaft on the shrinkage pool location that fastens; Force-output shaft is locked in end, the knob outside with the form of off-centre configuration, like this, when rotary knob, its steel ball is striden across block other steel balls that the shrinkage pool order that contains is adjacent and fall into shrinkage pool with it, have segmentation between knob and locating shaft and rotate localized effect and make, can make with eccentric form and be assemblied in the force-output shaft on the knob and the driving shaft angle direction that is arranged on the locating shaft changes, and then make the force-output shaft with the driving shaft other end have the effect that the multistage amplitude of oscillation is adjusted.This device by the snap-in structure of steel ball and shrinkage pool, reaches two-way rotation simultaneously between its knob and locating shaft, and then the amplitude of oscillation of fitness equipment can be adjusted to easily the effect of appropriateness.Because the periphery of this knob forms the rough pattern of Flos Mume head, it more meets the body mechanics, has reached the more comfortable effect of use that makes the operator.

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
