Kettle bell, kettle bell shell and production method of kettle bell

Abstract

The invention provides a kettlebell, a kettlebell shell and a kettlebell manufacturing method. The kettlebell includes a shell and a counterweight filled in the shell, an opening is provided at the bottom of the shell, and a Sealed cover, the counterweight is divided into liquid counterweight and solid counterweight respectively poured into the shell through the opening, the solid counterweight and liquid counterweight are mixed and condensed into one body with the inner wall of the shell and the cover . In the present invention, the weights of the kettlebell are divided into liquid weights and solid weights, which are respectively poured into the kettlebell shell through the opening. Now by mixing the two into a viscous fluid reperfusion process, the perfusion speed can be more than doubled. Moreover, the liquid counterweight and the solid counterweight are poured separately, and the mixed solidified body of water and cement that is difficult to clean will not be formed on the outer surface of the kettlebell, which provides convenience for subsequent cleaning and shaping of the kettlebell.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a kettlebell, a kettlebell shell, a manufacturing method of the kettlebell and a blow mold for the kettlebell shell. Background technique [0002] Weight training is physically and mentally beneficial lifting that develops skeletal muscle strength and size. 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. [0003] The structure of the kettlebell is as described in Chinese utility model patents CN2008200419157 and CN2009200452732, comprising a kettle-type plastic housing filled with filling weights. The filling weight is a solidified body mixed with yellow sand, ore sand, iron beads, cement and binder. Chinese inventi...

AI Technical Summary

Problems solved by technology

Judging from the overall descriptions of the above three invention patents, those skilled in the art can judge that the counterweight is mixed into a viscous fluid state by water, cement and yellow sand, and then poured into the cavity of the shell. The pouring method has the following disadvantages: (1) The liquid mixture needs to be kept in a stirring state, otherwise it will solidify; (2) The opening at the bottom of the shell is small, so it is best to use a funnel to pour, otherwise the mixture flows to the surface of the shell and solidifies It is difficult to clean up after the end, and it needs 2 people or 1 person plus 1 tooling fixture to complete it with the help of a funnel, which is not easy to operate; (3) It is difficult and slow to perfuse the fluid body
