Dumbbell device for training by utilizing fluid resistance

Abstract

The invention discloses a dumbbell device for training by utilizing fluid resistance. The device comprises a bed body, a position adjusting mechanism and a resistance training mechanism; the bed bodycomprises a bed plate, a mattress and a support; the position adjusting mechanism comprises a screw rod, a sliding seat and a servo motor; and the resistance training mechanism comprises a fluid cylinder, a piston seat, a connecting seat and a horizontal push rod. The device has the following beneficial effects: the device can replace a bench press dumbbell to be used, the acting force during training is provided through fluid resistance; during training, the training intensity is jointly determined by the number of opened through holes and the bench press speed during training; when trainingis started, the training intensity is preliminarily adjusted through adjustment of the number of opened through holes, and during training and when training is started, a body builder pushes or pullsdown a horizontal push rod at a high speed, the speed of pushing or pulling down the horizontal push rod can be reduced by himself / herself along with training, so that the training intensity can be reduced by himself / herself, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of fitness training devices, in particular to a dumbbell device for training using fluid resistance. Background technique [0002] More and more people in modern society are paying attention to the management of their body and health. Therefore, more and more people choose to enter the gym for physical exercise. Although there are many kinds of fitness equipment, they can be summed up in two categories: The first is the gravity type, which relies on lifting heavy objects to achieve the effect of exercise, and its representative equipment is dumbbells; the second is the elastic type, which relies on the rebound reaction force of the spring to achieve the effect of exercise, and its representative equipment is various spring tensioners. [0003] As one of the important exercise equipment, dumbbells are mainly used for muscle strength training, muscle compound movement training, patients with low muscle strengt...

AI Technical Summary

Problems solved by technology

[0004] The dumbbell used as the bench press exercise has many disadvantages in use: one, it relies on gravity to exercise, and when exercising, if the exerciser suddenly loses strength, it is easy to smash down and cause personnel injury; , the size of its gravity is adjusted by changing the number of weight blocks, which is inconvenient to adjust during use; thirdly, when the number of weight blocks set on it is determined, the strength it provides during exercise will also remain constant, while The optimal training intensity will be different when the exerciser is at the beginning and the end of the exercise. It is impossible for the trainer to adjust the training intensity by changing the number of weights all the time during training.
