Description

Self-weight type force training device

Technical field

The invention belongs to training device, especially relate to a kind of force exerciser.

Background technology

People are for body-building now, promote longevity, carrying out the training of strength day by day popularizes, now Chang Yong training device from the stone dumbbell in the form of an old-fashioned padlock, stone barbell, dumbbell, shoulder bell to by balancing weight or frictionally or by the experienced body apparatus of applied loads such as electromagnetic force, though it is various in style, but the stone dumbbell in the form of an old-fashioned padlock, stone barbell, dumbbell, weight relative fixed all of shouldering bell, can not become and regulated at will because of the people, protective is poor simultaneously, to people Yi Zaocheng unexpected injury, and by balancing weight or frictionally or complicated by the experienced body apparatus structure of applied loads such as electromagnetic force, price is more expensive, is difficult for popularizing.

Summary of the invention

The objective of the invention is to propose a kind of self-weight type force training device, not only simple in structure, and also the strength of training is suitable because of the people, adjustable size, and safe and reliable, popularize easily.

The object of the present invention is achieved like this: a kind of self-weight type force training device, frame is a portal, the left and right column of this frame can be the trapezoidal column of circular columns or channel column or sheet with rib, and stretch outwardly with contact-making surface and the raising anti-tilting complex torque of expansion with ground on the plane of the base plate of frame; On a left side, a sliding dress left side between the inboard of right column, the lifting seat board of right two ends tape guide frid, the groove face of guide groove plate is corresponding with the profile of column, be positioned at a left side, the middle hypomere position of right column, on a left side, all install subplate on the lateral surface of right column, on a left side, symmetrical uniform boring on right column and the subplate, be positioned at a left side, the inboard of right column, on a left side, symmetry installs the pulley spindle of threaded end section and tightens fixing with nut or bolt in the hole of right column, the installation site of pulley spindle is disposable, when being external screw thread, fixes thread segment with nut screwing clamping, when thread segment is internal thread, tighten fixing with bolt, bearing is installed on pulley spindle, the bearing cap of mounting strap truckle on bearing, truckle can be made axial step formula multiple-grooved combination wheel; Uniform installation alignment pin and bolt are installed large pulley on this alignment pin and bolt on the side of left and right truckle; The size of large pulley is interconvertible, large pulley can be made axial step formula multiple-grooved combination wheel, meanwhile, on a left side, a left side fixedly mounts respectively and reels on the right truckle, the epimere of bottom right stay cord, a left side, the lower end section of bottom right stay cord then correspondence is fixedly mounted on the lifting seat board, on a left side, a left side then fixedly mounts and reels on the right large pulley, the hypomere of upper right stay cord, a left side, the upper end section of upper right stay cord is then distinguished the two ends of corresponding cylinder lever connecting rod, change in radius by coaxial large pulley that installs and truckle, by input, the moment of torsion relation of output, thus the size that has changed the power that need apply is promptly tempered the size of load; Utilize body weight to form the counterweight of tempering load; During use, the people stands on the lifting seat board, both hands are held pull bar and are made to carry or go up the movement work, drive a left side, upper right stay cord makes a left side in the time of up, right large pulley rotation, a left side, right large pulley makes a left side when rotating, right truckle rotates synchronously, the coiling pull-down line also makes the lifting seat board rise together with the people, the both hands that make the people produce lifting force and play the training of strength, when people's both hands loosen, lifting seat board and people reset by the gravity effect, repeat above-mentioned action, carry out strength building by deadweight, change a left side, right large pulley can change amount of exercise, selects suitable hole to install pulley spindle to adapt to people's height; But the power free adjustment of training is safe and reliable.

The self-weight type force training device that the present invention proposes is simple in structure, and the strength of training is suitable because of the people, and adjustable size is safe and reliable, popularizes easily.。

Below in conjunction with drawings and Examples self-weight type force training device proposed by the invention is further described.
