Kettle-bell and manufacturing method thereof

Abstract

The invention relates to the technical field of kettle-bell and specifically to a kettle-bell. The kettle-bell comprises a knob and a kettle belly; the knob and the kettle belly are molded rotationally and integrally; the lower end surface of the knob and the upper end surface of the kettle belly are identical and are fixed in a welding manner. The rotational molding raw materials of the knob comprise raw materials with parts by weight as follows: 180-220 parts of polyvinyl chloride paste resin, 35-45 parts of a plasticizer, 14-18 parts of a viscosity reducer and 1-3 parts of a stabilizer; therotational molding raw materials of the kettle belly comprises raw materials with parts by weight as follows: 80-120 parts of the polyvinyl chloride paste resin, 20-40 parts of the plasticizer, 2-8 parts of epoxidized soybean oil, 2-6 parts of a viscosity reducer D-80 and 0.5-2 parts of a liquid calcium zinc stabilizer. The kettle-bell disclosed by the invention breaks through a traditional product concept that one kettle-bell has only one hand-feeling of hardness, enables a product molded at a time to have two different hardness; the manufacturing process is simple, the automatic welding isreliable and stable; the soft surface points downwards even the kettle-bell in use falls off, so the safety is greatly increased.

Description

technical field [0001] The invention relates to the technical field of kettlebells, in particular to a kettlebell and a manufacturing method thereof. Background technique [0002] Kettle bells are generally made of cast iron, and there are 10 kg, 15 kg, 20 kg, 25 kg, 30 kg and other specifications according to weight. In our country, there are also stone locks that look like locks, and their usage is roughly the same as that of kettlebells. When using kettlebells for fitness exercises, you can do various exercises such as pushing, lifting, lifting, throwing and squat jumping. The difference between kettlebell training and dumbbell and barbell training is that kettlebells are more effective in improving overall explosive power, so kettlebells and stone locks have always been loved by fighters and martial artists. [0003] Kettlebells are generally made of pure cast iron or plastic hollow blow molding and then poured with cement, iron sand and other counterweight mixtures to...

AI Technical Summary

Problems solved by technology

However, whether the traditional kettlebell is made of pure cast iron or plastic with weight, it is heavy and very hard. Once it is dropped during the practical process, it is likely to cause injuries to the legs and other body parts, and there is an uncertain safety hazard.
