Environment-friendly dumbbell and production method of environment-friendly dumbbell

Abstract

The invention relates to an environment-friendly dumbbell, which comprises a dumbbell handle body, wherein the dumbbell handle body comprises a case and filling materials, the case comprises the following ingredients including 34 percent to 36 percent of low-density high-pressure polyethylene, 2.9 percent to 3.1 percent of color masterbatch, 1.9 percent to 2.1 percent of drying agents and the balance of high-density low-pressure polyethylene, and the filling materials comprise the following ingredients including 18 percent to 21 percent of gel materials, 3 percent to 4 percent of efficient water reducing agents, 6 percent to 9 percent of mixing water and the balance of aggregate. The environment-friendly dumbbell has the beneficial effect that the major ingredient of the case of the dumbbell provided by the invention is polyethylene. Compared with the dumbbell in the prior art, the environment-friendly dumbbell prevents the rusting phenomenon of steel when being exposed in the air. In addition, the case adopts the polyethylene material as the major material, the damage to the ground when the dumbbell falls onto the ground is reduced, and in addition, the crushing injury phenomenon to people is reduced.

Description

Technical field: [0001] The invention relates to the technical field of fitness equipment, in particular to an environment-friendly dumbbell and a production process thereof. Background technique: [0002] Dumbbell is a kind of sports equipment that people often use when they do physical exercise. Dumbbell fitness does not require a special place, nor does it need to have any professional foundation. One can practice indoors, and it is very convenient to use. However, the traditional dumbbell shell is generally made of metal, and the weight is not adjustable, so it is inconvenient to place and carry, and it is easy to hurt yourself or others during use, and the production cost is relatively high. Moreover, existing dumbbells are generally made of metal and processed by casting. The manufacturing process of this type of dumbbell has the problems of high energy consumption, heavy pollution, low efficiency, and high cost. Invention content: [0003] The technical problem to ...
