Abstract
The present invention discloses an elasticity adjustment structure of physical training device which comprise one elastomer adjustment set; said elastomer adjustment set further comprises one first elastomer and one second elastomer. Overlapping the said second elastomer and said first elastomer with different rigidities at different depth positions to create a smooth elastic curve of said elastomer adjustment set; as a result the elasticity of said elasticity adjustment structure may be adjusted in accordance with different needs.
Claims8
An elasticity adjustment structure of physical training device, comprising:
- a punching bag;
- a connecting rod having a top end coupled at said punching bag and a bottom end, and defining a first rod junction at said bottom end and a second rod junction above said first rod junction;
- a base;
- and
- an elastomer adjustment set, which comprises:
- a tubular first elastomer, wherein a first junction of said first elastomer is connected to said second end of said connecting rod, and a second junction of said first elastomer is connected to said base;
- a tubular second elastomer, which has a rigidity higher than said first elastomer, wherein a first junction of said second elastomer is sleeved with said first elastomer and a second junction of said second elastomer is selectively coupled at one of different positions of said connecting rod to define an overlapping area between said first and second elastomer, such that said first junction of said second elastomer is adjustable to adjust a depth position on said first elastomer for adjusting said overlapping area so as to adjust an elasticity of said elastomer adjustment set.
An elasticity adjustment structure of physical training device, comprising:
- a punching bag;
- a base;
- a first connecting rod, wherein a top end of said first connecting rod is coupled at said punching bag, wherein a first rod junction of said first connecting rod is defined at a bottom end of said first connecting rod and a second rod junction is defined above said first rod junction;
- a second connecting rod, wherein a bottom end of said second connecting rod is upwardly extended from said base;
- an elastomer adjustment set, which comprises:
- a tubular first elastomer, wherein a first junction of said first elastomer is connected to said second end of said connecting rod, and a second junction of said first elastomer is connected to said second connecting rod;
- a tubular second elastomer, which has a rigidity higher than said first elastomer, wherein a first junction of said second elastomer is sleeved with said first elastomer and a second junction of said second elastomer is selectively coupled at one of different positions of said second connecting rod to define an overlapping area between said first and second elastomer, such that said first junction of said second elastomer is adjustable to adjust a depth position on said first elastomer for adjusting said overlapping area so as to adjust an elasticity of said elastomer adjustment set.
