Abstract

The invention provides an environment-friendly self-power-generating fitness chest expander, which comprises a bottom frame, wherein a seat cushion is mounted on the bottom frame, two ends of the seatcushion are respectively hinged with a back cushion and a leg supporting cushion, a guide rail is arranged in the bottom frame, a sliding block is mounted on the guide rail, the upper surface of thesliding block is hinged with the back cushion through a connecting rod, the right end is connected with the seat cushion through a tension spring, a counter is arranged at the left end of the bottom frame, a chest expander is arranged at the right end, a winding wheel is mounted in the chest expander, a detachable elastic component is arranged on the winding wheel, a pull belt is arranged on the winding wheel, and the tail end of the pull belt extends out of the chest expander and is fixedly connected with a handle. According to the invention, the tension of the chest expander can be adjusted;and the chest expander is suitable for people with different physiques and different exercising stages, has the effect of exercising muscles of more parts compared with ordinary chest expanders, haswide applicability, can charge mobile phones and other electric equipment through exercising power generation, virtualizes the exercising effect, stimulates the exercising enthusiasm of users, and hasgood development prospects.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a tensioner. Background technique [0002] Stretcher is a kind of fitness equipment used for arm flexion exercise to achieve the effect of exercising hand muscles. The muscles of the upper arm of the human body mainly include the biceps brachii and triceps brachii. The biceps brachii is a muscle with two muscle heads. , whose main function is to flex the arm. When bending the arm, another muscle, the triceps, is also used. Only through some forearm lifting movements, such as high tensioner curls or reverse high tensioner curls, can the brachialis be fully exercised. In addition, the main muscle on the upper part of the forearm, the flexor brachii, also plays a role in the flexion of the arms, and the flexor brachii can be strengthened by bending the side of the tensioner. [0003] However, the traditional tensioner has a simple structure, cannot adjust the elasticity of the ten...

AI Technical Summary

Problems solved by technology

[0003] However, the structure of the traditional tensioner is simple, and the elasticity of the tensioner cannot be adjusted, and it is impossible to carry out targeted training in stages, and it cannot be well adapted to users of different physiques. The exercise of the hand and chest muscles is rather boring, and it cannot mobilize the user's enthusiasm for exercise very well, which is not conducive to the user's long-term persistence in exercising
