Ligament traction device for track and field training

Abstract

The invention discloses a ligament traction device for track and field training, relates to the technical field of track and field training, and solves the problems that a ligament traction device used at present is mainly used for fixing a leg through a leg fixing structure and then unfolding the leg, the stress is mainly applied to the leg, the bearing force is large, and a ligament pulling structure facilitating whole body stretching does not exist. The ligament traction device for track and field training comprises a base. Two sets of leg seats are integrally arranged on the two sides of the rear end of the base, and lead screws are rotationally arranged on the adjacent sides of the two sets of leg seats; a top plate is fixedly arranged at the tops of the base and the leg seats; two sets of pre-moving motors are fixedly arranged in the base, and inner ratchet gears A are fixedly arranged at the shaft ends of the pre-moving motors. According to the invention, convenience is provided for ligament traction by arranging side plates, the legs can be rapidly lifted to the ligament stress position to be further slowly stretched through two stress modes, and the whole body can be conveniently stretched; the stretching efficiency is improved, and a single leg can be quickly stretched.

Description

technical field [0001] The invention relates to the technical field of track and field training, in particular to a ligament pulling device for track and field training. Background technique [0002] Athletics needs to stretch the leg ligaments during training, so it is necessary to use a ligament stretching device for assistance. Pulling the ligaments is actually a form of warm-up. Before strenuous activities, stretch the tendons to prevent sudden acceleration. Unbearable capacity, injury or rupture, ligament strain. By stretching the ligaments, the ability to withstand the curvature of the body and the extension ability of each limb can be improved. [0003] After retrieval, for example, the patent No. CN211935397U discloses a ligament pulling device for track and field training, which relates to the technical field of sports training, and is specifically a ligament pulling device for track and field training, including a base, and the top of the base is fixedly installed...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a ligament stretching device for track and field training, to solve the problem that the currently used ligament stretching device proposed in the above background technology mainly fixes the leg through the leg fixing structure and then unfolds it, and the force is mainly used for the leg. The lower part has a large bearing capacity, does not have a stretching ligament structure that is convenient for whole body stretching, does not have a stretching function for rapid stretching of a single leg, and is not conducive to rapid stretching
