Description

a dumbbell

technical field

The utility model belongs to the technical field of fitness equipment, in particular to a dumbbell plate.

Background technique

According to the production method, dumbbells are divided into blow-molded sheets, rubber-coated sheets, cast iron sheets and pure iron sheets, etc. Taking the blow-molded sheet and the rubber-coated sheet as examples, the blow-molded sheet is blow-molded first to make a plastic shell, and then pour cement slurry or mortar into the plastic shell, and form a counterweight after the cement slurry or mortar solidifies; The film body is to first make a counterweight, and then put the counterweight into a mold for injection molding, and the plastic shell wrapped on the surface of the counterweight is obtained by injection molding.

After the dumbbell plate is used for a period of time, the surface coating of the dumbbell plate will be detached, rusted and other problems, so it can only be scrapped. When dumbbells are recycled, the plastic shell is recyclable garbage, and the counterweight is construction waste, which needs to be discarded separately. Therefore, it is necessary to use a cutting machine to cut the plastic shell, crush the counterweight and take it out, so as to achieve classification. Recycling, and the general family does not have cutting tools such as cutting machines, and the risk factor of the operation is high, and the implementability is very poor.

Contents of the invention

The technical problem to be solved by the utility model is to provide a kind of dumbbell plate which is convenient for sorting and recycling, and the disassembly is relatively convenient.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a dumbbell plate, including a shell and a counterweight set in the shell, and the outer surface of the shell is provided with a Area.

The housing has two end faces and a side face, and the region is arranged on the end faces or the side face.

An easy-tear line is provided on the end face of the shell or on the side of the shell, and the two ends of the easy-tear line are connected to form the region. In this structure, one can directly tear the easy-tear line, thereby opening the area.

The end face of the housing or the side surface of the housing is provided with a bar-shaped groove, and the two ends of the bar-shaped groove are connected to form the area. In this structure, the shell is thinner at the bar-shaped groove, and people can use a utility knife to cut the bottom of the bar-shaped groove, and this area can be opened without using a large cutting tool.

The said area is set on the end face of the housing, and the end face of the housing is provided with a central hole, and the said area is staggered with the said central hole.

Two easy-tear lines are arranged on the end surface of the housing, the first easy-tear line surrounds the central hole, and the second easy-tear line surrounds the first easy-tear line. line, and the area is formed between the two easy-tear lines.

Two bar-shaped grooves are provided on the end face of the housing, the first bar-shaped groove surrounds the central hole, and the second bar-shaped groove surrounds the first bar-shaped groove. Grooves, the region is formed between the two strip-shaped grooves.

The outer surface of the housing is provided with a panel, the panel covers the area, the panel is fixedly connected to the surface of the housing located in the area, and the panel Releasably connected to said housing surface outside said region. When the shell needs to be opened, the panel is first separated from the shell outside the area to expose the area, and then the area is manually broken to allow the inside of the shell to communicate with the outside of the shell through this area; in addition, conventional blow molding Dumbbell plates only have a single color, and the appearance is monotonous. By increasing the panel structure, the appearance of the blow-molded dumbbell plates can be double-colored or more, and a more refined appearance can be produced.

The outer surface of the housing is inwardly recessed to form a receiving groove matching the panel, and the area is set at the bottom of the receiving groove.

The side of the panel facing the housing is provided with a plurality of non-intersecting first through slots.

The side of the panel away from the housing is provided with two second through slots.

Compared with the prior art, the utility model has the advantage that by setting the area that can be broken manually on the outer surface of the shell, when it needs to be sorted and recycled, people can directly break the area, and the hammer head can pass through the area at this time. This area knocks the counterweight in the housing, and the crushed counterweight can be poured out through this area, and finally the housing and the counterweight are separated, which is more convenient for disassembly, easy for classification and recycling, and meets environmental protection requirements.
