Shoulder passive stretching mechanism for training

Abstract

The invention relates to the technical field of training instruments, and discloses a shoulder passive stretching mechanism for training, which comprises a frame body, the interior of the frame body is movably connected with a first frame plate, and the outer side of the first frame plate is movably connected with a movable disc; through the combined action of the first frame plate, the movable disc, a first rotary disc and a second rotary disc, the two arms are automatically dragged, the two upper limbs are crossed and get close to each other in an arc-shaped track, the deltoid muscle is automatically and passively stretched without the assistance of other people, the movement amplitude of joints is increased, and the muscle stretching effect is improved; muscle soreness caused by exercise is effectively relieved and body fatigue is reduced, through the combined action of a third rotating disc, a ratchet wheel, a fixing frame, a chuck, a toothed wheel, a toothed rod and a toothed block, the height of the stretching equipment can be automatically adjusted according to personal needs, which can be suitable for people with different heights, stretching operation is facilitated, and the practicability and convenience of the equipment are improved.

Description

technical field [0001] The invention relates to the technical field of training equipment, in particular to a shoulder passive stretching mechanism for training. Background technique [0002] Physical training is the basic training in sports training. It uses a variety of training methods and means to develop athletes' physical qualities such as strength, speed, endurance, flexibility, and agility. Develop athleticism and improve body shape. [0003] Because the body muscles are in a state of tension and congestion after exercise, the muscles will be more tense and stiff than usual. If the muscles are in a state of tension and stiffness for a long time, the flexibility of the body will be reduced, and lactic acid will accumulate in the body after exercise. , Muscle soreness will occur later. In order to alleviate this situation, you need to stretch your body after exercise. Athletes often need to stretch the deltoid muscle of the shoulder with the assistance of others, so...

AI Technical Summary

Problems solved by technology

Athletes often need to stretch the deltoid muscle of the shoulder with the assistance of others, so that the muscles can get better relaxation effect, but this kind of passive stretching has relatively high requirements for the assistant, otherwise it is easy to cause muscle strain, and The existing stretching device requires manual adjustment of the use height, the operation is not very convenient, and it is impossible to pull and stretch the two upper limbs at the same time, the stretching efficiency is relatively low, and it is time-consuming
