Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is the structural diagram of the embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

(2) As shown in FIG. 1, the embodiment has hand wheel 1, lead screw 2, framework connecting nut 3, gravity scale indicating device frame 4 (a way of scale indication is used in this embodiment), plane press plate 5, plane press plate guiding pillar 6, upper frame beam 7, upper pulley block 81, lower pulley block 82, spring guiding pillar 9, upper spring seats 10, two springs 11, lower spring seat 12, spring guiding pillar connecting nut 13, lower frame beam 14, vortex track 15, big wheel 16, steel wire rope connecting the pulley block and the vortex track 17, steel wire rope connecting the big wheel and fitness equipment 18.

(3) Hand wheel 1 is fixed at the top of lead screw 2. Two springs 11 are arranged between the upper spring seat 10 and the lower spring seat 12. After going through two springs 11 and upper spring seat 10 and lower spring seat 12, two ends of spring guiding pillar 9 are connected to upper frame beam 7 and lower frame beam 14 respectively, to form foundation framework. Two springs 11 together with upper spring seat 10 and lower spring seat 12 move along spring guiding pillar 9, with both ends movable. Thread lead screw 91 is arranged at the lower end of spring guiding pillar 9, and spring guiding pillar connecting nut 13 is mounted on thread lead screw 91 of spring guiding pillar 9, for the functions of gravity adjustment, limit, shock absorption and impact resistance. Gravity scale indicating device frame 4 is fixed on upper frame beam 7. One end of lead screw 2 is connected with hand wheel 1, and the other end of lead screw 2 passes through framework connecting nut 3 which is fixed on gravity scale indicating device frame 4, and thus acting on the plane press plate 5 by rotations. An upper end of plane press plate guiding pillar 6 is connected with plane press plate 5, and a lower end of plane press plate guiding pillar 6 passes though upper frame beam 7 and is connected to upper spring seat 10. The rotations of lead screw 2 act on plane press plate 5 and move plane press plate guiding pillar 6 and upper spring seat 10 accordingly to adjust the length of two spring 11. Upper pulley block 81 passes though upper spring seat 10 and is mounted on upper frame beam 7, and the lower pulley block 82 is mounted on lower spring seat 12. One end of steel wire rope 17 connecting pulley block and vortex track is fixed to one side of lower pulley block 82, then goes around upper pulley block 81 and lower pulley block 82. The other end of steel wire rope 17 connecting pulley block and vortex track is connected with vortex track 15, and vortex track 15 is engaged with big wheel 16 synchronously or asynchronously. One end of steel wire rope 18 connecting big wheel 16 and fitness equipment is fixed to big wheel 16. After going around big wheel 16, the other end of steel wire rope 18 connecting big wheel and the fitness equipment is connected with the fitness equipment. When the user operates the fitness equipment, big wheel 16 and vortex track 15 are moved by steel wire rope 18 connecting pulley block and vortex track. The rotations of vortex track 15 change the stress radius of steel wire rope 17 connecting pulley block and vortex track, at the same time, lower spring seat 12 and two springs 11 are pulled by steel wire rope 17 connecting pulley block and the vortex track though the lower pulley block 82.

(4) The invention has a spring energy regulating box, at least one pulley block, the vortex track, the big wheel, and the steel wire rope. The spring energy storage regulating box has at least one spring. The both ends of the spring are arranged on the spring seats, moving along the spring guiding pillar, with both ends movable. A gravity calibration device is located at one end of the spring energy regulating box. The thread is arranged on the spring guiding pillar, engaging with the adjustment nut to calibrate the benchmark gravity. The gravity indicating device which is adjusted by the thread lead screw is located at the other end of the spring energy regulating box. The spring strength is set by the gravity indicating device. A group of pulley blocks is mounted on the frame beam, and the other group of pulley blocks which passes through the spring seat and is mounted on the other spring seat. One end of the steel wire rope is fixed on the pulley block and goes around the pulley blocks, and the other end of the steel wire rope is fixed on the vortex track, which is engaged with the big wheel synchronously or asynchronously. The steel wire rope is fixed on the big wheel. One end of the steel wire rope is fixed on the big wheel. After going around the big wheel, the other end of the steel wire rope is fixed on the fitness equipment. When operating the fitness equipment, the vortex track and the big wheel are pulled by the steel wire rope contacting the big wheel. The stress radius of the steel wire rope along the vortex track is changed by the function of the vortex track, so that the force reaches to balance or within the set range. The force can be any balance force or the force within the set range by adjusting the gravity scale indicating device.

(5) Although the invention is showed and described with a preferable embodiment, the ordinary skilled in the art should understand, within the spirit and scope of the invention, without departing from the appended claims, the various changes to the invention in the forms and details fall within protection scope of the invention.
