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

Abstract

The invention provides a kettle bell, a kettle bell shell and a production method of the kettle bell. The kettle bell comprises a shell and a counter weight filling the inside of the shell, wherein an opening is formed at the bottom of the shell; a cover sealing the opening is arranged at the opening; the counter weight is classified into a liquid-state counter weight and a solid-state counter weight which are poured into the shell through the opening respectively; and the solid-state counter weight and the liquid-state counter weight are mixed and then condensed with the inner wall of the shell and the cover. In the invention, the counter weight of the kettle bell is classified into a liquid-state counter weight and a solid-state counter weight which are poured into the shell of the kettle bell through the opening respectively; the liquid-state counter weight and the solid-state counter weight have relatively high fluidity and are convenient to pour; and compared with existing technology of mixing the two into a thick fluid before pouring, the pouring speed can be at least doubled. Moreover, the liquid-state counter weight and the solid-state counter weight are poured separately, the hard-to-clear mixed solidified object of water and cement is not formed on the outer surface of the kettle bell, and convenience is provided for follow-up cleaning and shaping of the kettle bell.

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...

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
