Elasticity adjusting mechanism for fitness gravity frame and fitness gravity frame

Abstract

The invention discloses an elasticity adjusting mechanism for a fitness gravity frame and the fitness gravity frame, which relate to the technical field of fitness equipment, and solves the technicalproblem that the elasticity of an elastic rope needs to be adjusted in the prior art. The elastic force adjusting mechanism comprises a wire wheel assembly, an adjusting assembly and a gear assembly;wherein the wire wheel assembly is used for winding an elastic rope; the wire wheel assembly comprises a first wire wheel and a second wire wheel; the adjusting assembly is used for adjusting the position of the gear assembly, the first wire wheel is connected with the adjusting assembly and / or the gear assembly, the position of the gear assembly is adjusted through the adjusting assembly to drivethe first wire wheel to move, and therefore the elasticity of the elastic rope is adjusted by adjusting the distance between the first wire wheel and the second wire wheel. According to the elastic force adjusting mechanism, the elastic force of the elastic rope is adjusted by adjusting the distance between the first wire wheel and the second wire wheel, the structure is simple, the elastic forceis convenient to adjust, and the requirements of users for different elastic forces can be met.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an elastic force adjustment mechanism for a fitness weight frame and a fitness weight frame. Background technique [0002] With people's pursuit of quality of life, fitness is getting more and more attention. In order to meet this demand of people, various body-building equipments have occurred in the prior art, and fitness gravity frame is exactly one of them. In the fitness gravity frame in the prior art, its main component is an elastic cord. One end of the elastic cord is connected to the main frame body of the gravity frame, and the other end is connected to the handle. The user holds the handle and stretches the elastic cord to exercise. The effect of arm strength as well as body strength. [0003] In order to make the fitness gravity frame suitable for different groups of people, it is necessary to adjust the elastic size of the elastic rope to meet the fitness...
