A precision adjustable strength training aid

Abstract

The invention provides a precisely regulated strength training auxiliary instrument. The auxiliary instrument is characterized by comprising a frame, a cross bar slide rail, a magnetic powder brake mounting bracket, a magnetic powder brake, a cross bar, slide blocks, a fixed pulley block, a velocimeter slide rail, a velocimeter slide rail base, a velocimeter, a tension controller, an upper electric limiting block, a lower electric limiting block, a wire rope and a main circuit diagram, wherein the frame has a pair of parallel symmetrical inverted T-shaped structures and comprises a base and a vertical column which is fixedly vertically connected with the middle point of the base; the slide rail is parallel to the vertical column at same altitude and reserves a sliding space for the slide blocks relative to the outer side of the vertical column; the magnetic powder brake mounting bracket is fixedly mounted on the lower part on the rear side of the frame; the magnetic powder brake is mounted on the bracket; the cross bar is in sliding connection with the cross bar slide rail through the slide blocks fixedly connected at the two ends; the fixed pulley block is respectively fixed on the base and the magnetic powder brake mounting bracket; the velocimeter is fixed at the right end of the cross bar; the tension controller is arranged on the right side of the frame.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an auxiliary device for strength training that can be precisely regulated. Background technique [0002] Strength training equipment is a commonly used equipment for competition, fitness and bodybuilding in sports. At present, most of the training equipment used in strength training is a barbell, which can be loaded or unloaded by adding or reducing barbell plates of different weights, especially for high-level athletes in the practice of maximum strength or overload strength training, through the load. Automatic precision adjustment can be closer to the limit value of the human body, which is helpful to create the best strength training effect and performance; the current strength training with the help of barbells, there are problems. First, the minimum range of load increase and decrease is 0.5kg, which cannot be more precise. The second is that it is easy to cause p...

Problems solved by technology

At present, most of the training equipment used in strength training is a barbell, which can be loaded or unloaded by adding or reducing barbell plates of different weights, especially for high-level athletes in the practice of maximum strength or overload strength training, through the load. Automatic precision adjustment can be closer to the limit value of the human body, which is helpful to create the best strength training effect and performance; the current strength training with the help of barbells, there are problems. First, the minimum range of load increase and decrease is 0.5kg, which cannot be more precise. The second is that it is easy to cause personal injury due to overload during the training process, and the safety factor is low; the third is that frequent loading and unloading of the barbell also brings more trouble to the trainer, especially when men and women mix a barbell for strength. Training is more inconvenient
