Abstract

The invention relates to a formula of a bodybuilding tension spring. The formula of the bodybuilding tension spring is characterized by comprising, by weight, 30-36 parts of steel, 22-24 parts of copper, 3-6 parts of potassium silicate, 11-15 parts of calcium sulfate, 4-8 parts of titanium dioxide, 13-16 parts of calcium silicate, 16-19 parts of polyethylene, 5-8 parts of ferroferric oxide, 1-4 part of polyethylene glycol, 4-7 parts of chlorinated polyethylene, 3-6 parts of aluminum hydroxide, 2-3 parts of dioctyl phthalate and 5-8 parts of magnesium oxide. The tension spring is long in service life, high in anti-fatigue strength and high in safety performance.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a formula for fitness extension springs. Background technique [0002] As a kind of mechanical application equipment in fitness equipment, extension spring is a very suitable way for strength training according to its elastic potential energy, so the development of extension spring in fitness has been paid more and more attention. Ordinary fitness extension springs are poor in material, poor in fatigue resistance, low in service life, and low in safety performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-fatigue resistance and high-safety fitness extension spring material formula. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a formula for body-building extension springs, the innovation of which is: according to the weight ratio, ...
