A parallel bar arm strength fitness device with labor-saving function

Abstract

The invention discloses a parallel bar arm power fitness device with a power-saving function. The device comprises a transmission box body, wherein vertical adjusting lead screw shafts are arranged atfour corners of the upper end surface of the transmission box body; an adjusting motor is also arranged in the transmission box body; the main shaft of the adjusting motor is connected to the lower end shaft section of each adjusting lead screw shaft through a transmission mechanism; the lower end shaft sections of two adjacent adjusting lead screw shafts are connected through the transmission mechanism too; the bottom ends of two connecting rods on the same side are connected and fixed through a supporting plate; a magnet plate is arranged on the lower end surface of the supporting plate; anelectromagnet opposite to the magnet plate is arranged on the upper end surface of the transmission box body; the electromagnet is as same as the magnet plate in magnetic pole in opposite face; and aslide rheostat and an electrifying button are also arranged on the side wall of the transmission box body. The device disclosed by the invention is simple in structure, can save power to protect armsduring exercise, is better in adaptability, suitable for people of different heights, and is power-saving, can perform exercise step by step, and is relatively high in practicality.

Description

technical field [0001] The invention relates to a physical fitness apparatus, in particular to a parallel bar arm strength fitness device with a labor-saving function. Background technique [0002] So far, the single and parallel bars, as two kinds of exercise equipment, are generally fixed and installed outdoors, so people often see people exercising their arm strength outdoors, while outdoor parallel bars exercise is less safe, and many exercisers do not have enough arm strength to support them at the beginning. The body is upward, so that the arm is easily injured when exercising, and the exercise effect is relatively poor, and the double poles cannot be adjusted and cannot be adapted to the exercise of people of different heights. Contents of the invention [0003] The object of the present invention is to provide a parallel bar arm strength fitness device with a labor-saving function, so as to solve the problems raised in the above-mentioned background technology. ...
