Problems solved by technology
As we all know, gravity blocks of different sizes meet the needs of different groups of people. However, it is a troublesome thing to replace gravity blocks on the same barbell. Secondly, even if many barbells with different gravity are installed, so many barbells are stacked together. Occupies the floor area, thus resulting in a lot of waste of resources
In addition to the above disadvantages, sometimes people slipped their hands or made mistakes and caused the barbell to drop suddenly, which not only hurt themselves, but also caused safety hazards to others

Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] like Figure 1 to Figure 3 As shown, a spring barbell includes two symmetrically arranged training units 1, the training unit 1 includes a base plate 2 and a fixed platform 4 above the base plate 2, and the base plate 2 is fixedly provided with three To the evenly distributed uprights 3, the fixed platform 4 is fixedly arranged on the top of the uprights 3, the uprights 3 are provided with rotatable leading screws, and the corresponding uprights 3 are p...

The invention discloses a spring-type barbell, comprising a training unit and a barbell rod. The training unit comprises a bottom plate and a fixed platform. The bottom plate is provided with a column, the column is provided with a lead screw, the lead screw is provided with a stepping motor and a slider, the slider is connected with a parallelogram mechanism, and the parallelogram mechanism is connected with a moving platform. The movable platform is provided with a spring, and the spring is provided with a gravity block. The device of the invention is convenient to operate and can effectively exercise shoulder strength and muscles of a human body. Through the combination of two training units, the rigidity of the body is greatly increased. At the same time, the spring barbell is based onthe compression of the spring to control the shoulder force, the individual according to the actual situation to carry out the shoulder load, such a cushioning force makes people's shoulders are noteasy to hurt. The invention greatly compensates for the defect of the training shoulder of the general traditional barbell, and can safely and efficiently carry out shoulder training.
Description
technical field [0001] The invention relates to the technical field of sports equipment, in particular to a spring-type barbell. Background technique [0002] The spring barbell is a kind of barbell weightlifting, but this structure loses its working ability because the spring often reaches the fatigue limit. Despite its limitations in this regard, it still has enormous social benefits in the long run. Existing barbell structures are equipped with different gravity blocks on both sides of the barbell, because people's body structures are different, and the load-bearing capacity of the barbell is also different. As we all know, gravity blocks of different sizes meet the needs of different groups of people. However, it is a troublesome thing to replace gravity blocks on the same barbell. Secondly, even if many barbells with different gravity are installed, so many barbells are stacked together. Occupies the floor area, thus resulting in a waste of many resources. In additio...
