Abstract

The invention relates to a tension exercise device, in particular to a conveniently adjustable tension exercise device. The technical problem of the present invention is to provide a conveniently adjustable tension exercise device that can be easily adjusted and can improve exercise efficiency. The technical embodiment of the present invention is: a conveniently adjustable tension exercise device, including a shell, a mounting plate, a first pulley, a second pulley, a first pull cord, a pull plate, a handle device, a limit block, a first pulley Spring, fixed plate, etc.; the right part of the shell is provided with a mounting plate, the left part of the front side of the mounting plate is rotatably connected with a plurality of first pulleys that can guide the first pull cord, and the left part of the rear side in the shell is rotatably connected with Second pulley. The present invention can carry out tension exercise by continuously pulling the handle device to the left, and can adjust the elastic force of the first extension spring by moving the slide plate left and right to a suitable position, so that the difficulty of tension exercise can be adjusted, and the tension can be increased Exercise efficiency.

Description

technical field [0001] The invention relates to a tension exercise device, in particular to a conveniently adjustable tension exercise device. Background technique [0002] In order to prevent muscle atrophy caused by athletes who have not exercised for a long time, athletes will perform quantitative pulling exercises every day. At present, when performing pulling exercises, athletes usually move upwards by constantly pulling heavy blocks to exercise, and each heavy block They are all conventional weights, so it is difficult to meet the needs of athletes, and it is inconvenient for athletes to adjust them, which will reduce the efficiency of tension exercise. In order to improve exercise efficiency, athletes will combine weights of different weights. Increase the workload of athletes. Contents of the invention [0003] In order to overcome the shortcomings that each weight block is a conventional weight, it is difficult to meet the needs of athletes, and it is inconvenien...
