Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] like figure 1 Shown: the present invention comprises a steel wire 1 and an elastic filling layer 2, the steel wire is multi-strand, and the multiple strands of the steel wire are bent into groups and juxtaposed, and the elastic filling layer is composed of natural rubber, nitrile rubber, vinyl resin, and polyurethane The prepolymer composition of emulsion, highly active polymer polyol, ethylene glycol, diethanolamine, triethylenediamine, silane surfactant, diphenylmethane diisocyanate and polyether polyol; the elastic filling layer will The steel wire is covered inside.

[0017] Specifically, according to the weight ratio, 30% of the natural rubber, 30% of the nitrile rubber, 13% of the vinyl resin, 13% of the polyurethane composite emulsion, 2% of the high active polymer polyol, the 2% of the ethylene glycol, 2% of the diethanolamine, 2% of the triethyldiamine, 2%...

Abstract

The invention discloses a high-elasticity fitness chest expander, which comprises multiple strands of steel wires and an elastic filling layer, wherein the multiple strands of steel wires are bent and are arranged in groups side by side; the elastic filling layer consists of natural rubber, nitrile rubber, vinyl resin, a polyurethane composite emulsion, high active polymer polyol, ethylene glycol, diethanol amine, triethylenediamine, a silicane surfactant, diphenylmethane diisocyanate and a prepolymer of polyether polyol; and the steel wires are covered in the elastic filling layer. Compared with the prior art, the chest expander disclosed by the invention has the advantages of high elasticity and sufficient tension, and the elasticity is not easy to decline; by internally arranging the steel wires, the circumstance that the steel wires are broken by pulling is avoided; and the chest expander is convenient to use and has values of popularization and application.

Description

technical field [0001] The invention relates to a kind of sports body-building equipment, in particular to a high-elastic body-building tensioner. Background technique [0002] The tensioner is a device suitable for mass fitness exercises. The advantage of using a tensioner to exercise is that the biceps is a muscle with two muscle heads, and its main function is to bend the arms. When you bend your arms, you also use another muscle—the triceps. The brachialis muscles can only be fully exercised when doing some forearm lifting exercises, such as high-position tension machine curls or reverse high-position tension machine toys. 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. However, in the prior art, most of the tensioners are springs, the tension of the spring is too heavy, the elasticity is insufficient, and th...
