Abstract
The utility model provides a PVC (Polyvinyl Chloride) gravity ball which is characterized by comprising a hollow ball shell, and the hollow ball shell comprises a PVC outer layer and a weight-increased inner layer connected with the PVC outer layer. The utility model has the advantages that because the PVC outer layer is connected with the inner layer under the action of weight increasing, the problem of flowing filler does not occur; the center of gravity of the ball is fixed; and moreover, because the inner side of the ball is hollow, the excellent elasticity of PVC can be exerted, and the problem of poor elasticity of the ball is solved.
Description
Technical field
The utility model relates to a kind of PVC gravity ball, belongs to body-building apparatus industry technology field.
Background technology
Existing PVC gravity ball is after the moulding of PVC spheroid, adds filler in the spheroid the inside, as yellow sand, iron sand etc., and to promote the weight of whole spheroid, the purpose that reaches training and take exercise.Its main shortcoming is:
1, after filler joins the spheroid the inside, can not complete filling expire, the inside also has the part air, and the space is perhaps arranged.Can cause people when taking exercises, the center of gravity of spheroid changes along with flowing of filler.
2, after filler joined the spheroid the inside, original resilient spheroid can change the elasticity of whole spheroid because after having added filler inside the spheroid.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned two problems, and a kind of PVC gravity ball is provided.
In order to achieve the above object, the technical solution of the utility model provides a kind of PVC gravity ball, it is characterized in that, comprises hollow ball shell, and described hollow ball shell comprises that is increased the weight of an internal layer.
Described hollow ball shell also comprises a PVC skin, and described PVC skin is located at and is increased the weight of the internal layer outside, and with increase the weight of internal layer and be connected.
Described hollow ball shell is sphere or elliposoidal.
One side of described hollow ball shell or relative both sides have handle.
The utility model has the advantages that: since PVC outer with work the internal layer that increases the weight of to act on and link together, do not have the mobile problem of filler, the center of gravity of spheroid is fixed.And because the spherical shell inboard is hollow, the superior elasticity of PVC can access performance, has solved the not good problem of elasticity of spheroid.
