Description

Rotating body structure

Technical Field

The present invention relates to a rotating body structure, and more particularly, to a rotating body structure with silence and silence during rotation.

Background

First, referring to fig. 7 and 8, the inventor previously disclosed a rotating body 50, the rotating body 50 including two

shells

61,62, a set of connecting surfaces 63 formed at each opposite position of the

shells

61,62, and a ball groove space 64 disposed inside the rotating body 50, the ball groove space 64 including two groove wall surfaces 65 defined at radial intervals, and a circular channel 66 formed at the bottom surface of the inner periphery of the ball groove space 64; two notch spaces 52 are provided on both outer sides of the rotary body 50; two arc handles 54 are respectively arranged at the outer edges of the concave notch spaces 52; a gravity ball 70 is disposed within the ball slot space 64 for free rolling movement. Therefore, when the user holds the arc handles 54 as the pivot point of the rotation shaft and rolls the gravity ball 70 along the circular path 66 of the ball slot space 64, the user can rotate the rotation body 50 by the force of the gravity ball 70, so that the gravity ball 70 rolls along the circular path 66 to generate the centrifugal force, and the user can exercise the wrist by the centrifugal force. However, the noise generated by the gravity ball 70 rubbing the ring 66 during rolling, besides being annoying, further limits the service time of the rotating body 50.

Furthermore, please refer to the utility model publication No. CN201482050 again, because the weight member is in an eccentric rotation state with two rotating arms, when two holding members are held by two hands and the weight member is rotated, there is no fixed axis, so that the continuous swing amplitude and angle of the two hands are not consistent and are changed at any time during the force application process of the two hands, which often results in the unsmooth rotation of the weight member and the pause condition; meanwhile, the first connecting portion and the second connecting portion of the arm body can gradually generate a loosening gap due to the fact that no fixed axis exists under the long-time rotation, and the counterweight piece can be clamped and stopped due to the fact that the counterweight piece cannot rotate smoothly.

In view of the above, the inventor of the present invention has made various experiments on the manufacturing, development and design of related products for many years, and has made a detailed design and a careful evaluation to the above-mentioned objects, and finally, has obtained a practical invention.

In view of the fact that the conventional centrifugal exercise device generates annoying noise during use, the time of use is limited, and the structure is complicated, so that the assembly cost and the part cost are high, and the sale is not good.

shells

20 and 21 when rotating, so that the weight block 36 is silent and smooth when rotating.

(II), referring to fig. 2 and 4, when using the rotator 10, the user can also fit the palms of both hands to the two concave slot spaces 12, so that the two concave slot spaces 12 are pivot points of the rotation axis, after the user applies force, the weight block 36 rotates in the two containing grooves 22 and generates centrifugal force, the user can rotate the rotator 10 by force, and the wrist limb moves by the centrifugal force, because the weight block 36 is combined with the rotation part 32, the weight block 36 will not generate friction with the inner wall surfaces of the two

shells

When using the rotator 10, the user can put both feet through the two operation parts 14, and make the two operation parts 14 present the pivot of the rotation axis, and then apply force to make the weight block 36 rotate in the containing groove 22 and generate centrifugal force, the user can make force rotate the rotator 10, and by means of the centrifugal force, the wrist or the limb movement of both feet, because the weight block 36 is combined with the rotation part 32, the weight block 36 will not generate friction with the inner wall of the two

shells

20, 21 when rotating, so that the weight block 36 will be silent and smooth when rotating.

And (IV) because the two

shells

shells

20 and 21 and applies force by using the two operating parts 14 as rotating shaft supporting points, the linear distance between the two hands is fixed in the process of continuous swinging of the two hands, and the continuous swinging amplitude and angle of the two hands are consistent, so that the rotating part 32 and the balancing weight 36 in the rotating body 10 can be smoother.

Fifthly, after the two

shells

20 and 21 are mutually covered and fixed, two ends of the mandrel 30 are embedded in the corresponding embedding grooves 24 through two bearings 34; therefore, the rotation of the two ends of the spindle 30 has a fixed axis, and the continuous swing of the rotating member 32 located at the center of the spindle 30 can be ensured to be smooth without deflection.
