It has a kettlebell body and a handle (1) connected thereto, and is characterized in that the kettlebell body has an outer layer (2) and a core (3), and the outer layer (2) and the core (3 ) are cast from different materials. The utility model has the positive effects of natural and smooth appearance, precise product size, firmness and durability, and not easily damaged.

Description

New Composite Structure Kettlebell

technical field

The utility model relates to fitness and sports equipment, in particular to a kettlebell.

Background technique

The currently used kettlebell, as shown in Figure 1, is made of cast iron material by one-time casting using a traditional sand casting process. The surface is rough, and there are many defects such as sand holes and pores, so it is necessary to cover the defects with putty and other covering materials. Moreover, its biggest disadvantage is that the handle is prone to breakage, resulting in a serious waste of resources.

Contents of the invention

The purpose of the utility model is to provide a novel composite structure kettlebell to achieve the purpose of solid structure, smooth appearance, novelty and beauty.

The novel composite structure kettlebell provided by the utility model has a kettlebell body and a handle connected thereto, and is characterized in that the kettlebell body has an outer skin and a core; the outer skin and the core are made of Different materials are cast separately.

Wherein, the outer layer of the kettlebell body can be processed by any one of cast steel, aluminum alloy, and stainless steel; the core body can be made of any one of cast iron, lead, and concrete.

Novel composite structure kettlebell provided by the utility model, its positive effect mainly is:

1. The outer layer is made of materials with good processing performance. It can be mechanically shaped and precision processed to obtain a beautiful appearance. The surface is naturally smooth and the product size is precise.

2. The core body is made of relatively cheap materials, which can reduce the production cost on the premise of providing sufficient weight.

3. The outer layer and the core body can be compositely formed by secondary casting, which is durable and not easy to be damaged.

Description of drawings

Fig. 1 is the kettlebell sectional structure schematic diagram of prior art;

Fig. 2 is a schematic cross-sectional structure diagram of the utility model.

Detailed ways

As shown in Figure 2, the novel composite structure kettlebell provided by the utility model has a kettlebell body and a handle 1 connected therewith. The kettlebell body has an outer skin 2 and a core 3 .

Wherein, the outer layer 2 of the kettlebell body can be formed by casting any one of cast steel, aluminum alloy and stainless steel, preferably cast steel. The core body can be made of any one of cast iron, lead, and concrete, with cast iron being preferred.

The outer layer and the core body of the kettlebell body of the utility model can be compositely formed by secondary casting, that is, the outer layer is cast by any material such as cast steel, aluminum alloy, stainless steel, etc., and then cast iron is cast into the outer layer again. , lead, concrete and any other material to form the core. Apparently, in order to realize the above processing technology, the outer layer should have a sprue 4 for secondary casting after molding.

In addition, the outer layer 2 of the kettlebell body of the utility model and the handle 1 can be fixedly connected by welding, bolts, etc., but it is better to form an integral structure through one-time casting, which has the characteristics of being more durable.

Claims (2)

1. A new composite structure kettlebell, which has a kettlebell body and a handle (1) connected thereto, characterized in that the kettlebell body has an outer layer (2) and a core (3), and the The outer layer (2) and the core body (3) are respectively cast and formed from different materials. 2. The novel composite structure kettlebell according to claim 1, further characterized in that the outer layer (2) and the core (3) are compositely formed by secondary casting, that is, the outer layer is made of cast steel, Any one of aluminum alloy and stainless steel is casted, and the core body is re-cast inside the outer layer by any one of cast iron, lead, and concrete.
