Abstract
An improved range adjusting device of parallel walking machine comprises a base, a rocker, a pedal, a connecting bar and a damping component, wherein the middle part of the rocker is provided with lugs, the rang adjusting device is pivoted between the lugs, the range adjusting device consists of a bushing, a left screw rod and a right screw rod; the inner end of the opening of the bushing is provided with threads, the opposite inner ends of the left and right screw rods have at least one segment spirally arranged in the two ends of the bushing, the outer end part is pivoted on the lugs by a positioning piece, the screw threads of the screw rods are arranged in negative directions; the left and right screw rods synchronously act in opposite direction by rotating the bushing to transversely expansion control the flare angle of the two rockers and adjust the range, which is very convenient. When unused, the pedal is connected with the base hemline and leans against the top surface of a longitudinal tube to make the left and right pedals in a closed state, thereby being convenient for storing without occupying extra space; when the bushing is rotated, two screw rods synchronously extend and contract in opposite direction to speed up the adjustment while the bushing is arranged between the two lugs all the time to make the expansion distance of the two rockers in an equilibrium state, thereby side-to-side treadling movement is more steady and smooth.
Description
One, technical field
The utility model relates to body-building apparatus, relates in particular to a kind of adjustment design by horizontal and symmetery tension, makes the treadmills structure firm, and adjustment is swift in motion, and the adjusting device for travel of the improved parallel treadmills that can conveniently fold.
Two, background technology
Treadmills is to trample above it for the human foot, to reach the purpose of sport and body-building.As shown in Figure 1, be existing a kind of treadmills 1, its left and right two pedals, 11 front ends utilize pivot 12 to be articulated in pedestal 13, and the bottom is provided with the damping element 14 that two oil hydraulic cylinder or air pressure rods are constituted, and tramples resistance to provide.This treadmills in use, sole is and tilts forward and back alternately variable condition.
Consult shown in Figure 2, be existing another kind of treadmills 2, its primary structure as shown in Figure 3, Figure 4, form by a base 21, two damping elements 22, two connecting rods 23, two pedals 24, a master rocker 25, a secondary-rocker 26 and an adjusting device A, be provided with a base portion 211 in the middle of the base 21, this base portion is for pivot dress master rocker 25 and secondary-rocker 26, pedal 24 is established at the top of this master rocker 25 and secondary-rocker 26 respectively, join handicapping Buddhist nun element 22 respectively on two pedals, 24 boundaries between base 21 again, alternately to trample body building used to be provided as.More than shown in structure be prior art (PR10R ART), be widely used in the existing parallel treadmills, do not give unnecessary details so its manner of execution holds.
As Fig. 2, Fig. 3, treadmills 2 shown in Figure 4, it is provided with one stroke adjusting device A, comprise screw rod 27, pivot pin 28 and hand nut 29, these screw rod 27 bottoms radially pipeline section 271 vertically penetrate in the through hole 261 of secondary-rocker 26, it is fixed to give pivot with pivot pin 28, screw 281 again, then its top is passed continous action base 251 and is locked a hand nut 29; By unscrewing or screw tight a hand nut 29, adjust the start point of master rocker 25 and secondary-rocker 26, and then change pedal 24 strokes.But this adjusting device for travel A has following shortcoming in the use: 1, because treadmills 2 must be able to carry the total weight of human body, 30 kilograms of the lighters, weight person will be more than the 70-100 kilogram, its load-bearing is not difficult, and its stressed must equilibrium be good, to avoid stress concentration at certain a bit; The master rocker 25 of aforementioned treadmills 2 is integrally welded with continous action base 251, be articulated on the U type pedestal 211 by bolt 252 again, therefore, as shown in Figure 4, when human body gravity W acts on the pedal 24 of the right R, because master rocker 25 is that weldering is dead fixing with continous action base 251, therefore no problem is compared in load-bearing, but when human body gravity W effect left side L, because secondary-rocker 26 is to utilize the pivot pin 28 of adjusting device for travel A laterally to be connected with continous action base 251, so whole gravity W has major part to be concentrated in the radially pipeline section 271 of pivot pin 28 and screw rod 27 very much, like this behind the reciprocating, cause lax easily or distortion, even cause stress to be concentrated and the problem of fracture.2, fix owing to master rocker 25 and continous action base 251 are skewed welding, cause when master rocker 25 is the level of state, continous action base 251 is skewed U-shaped pedestal 211 tops that are positioned at, and master rocker 25 presents non-left and right equilibrium state with secondary-rocker 26; So not only bad for folding, and overall structure presents the both sides energy imbalance easily when left and right alternating movement, and smooth degree is relatively poor.3, utilize the rotation of hand nut 29, adjust directly flexible to screw rod 27, stretching, extension angle with control secondary-rocker 26, because this screw rod 27 is tiny, it is slower to regulate the speed, and it helps not quite to cause major and minor rocking arm 25,26 V-shaped shapes to the intensity in conjunction with 251 of continous action bases, the centre does not have cross-brace power, reduces structural strength.
