Abstract

A selective counterweight for sports apparatus is composed of a plastic casing with filling hole and its plug, intalling hole, locating hole, reinforcing ribs, and locating boss and recess, and the filler which is the mixture of water, cement and sand or steel sand and can be filled in said plastic casing via said filling hole.

Description

technical field [0001] The invention belongs to sports equipment accessories, in particular to a selection iron counterweight. Background technique [0002] At present, in the common sports equipment, the iron counterweights are selected to be matched with traditional iron counterweights. This kind of iron counterweight needs to be shaped by complex processes such as turning, milling, grinding, and grinding during the production process, which is laborious, expensive, loud in motion, easy to break, and has a short service life. Contents of the invention [0003] The object of the present invention is to provide a selective iron counterweight that is easy to manufacture, saves labor and effort, is low in cost, has low motion noise, is not easy to break, and has a long service life. [0004] The invention includes a casing and a filler; the casing is set as a polygonal box with a cavity inside, and a filling hole and a closing...
