Dynamics gradient physical trainer counterweight device and counterweight method

Abstract

The invention discloses a dynamics gradient physical trainer counterweight device and a counterweight method. The dynamics gradient physical trainer counterweight device is characterized by comprising a fluid storing bucket and a lifting bucket; the bottom part of the lifting bucket is reversely buckled in the fluid storing bucket upwards, and the center of the lifting bucket is connected with a traction part; an exhaust hole is arranged on the bottom of the lifting bucket, and the exhaust hole is provided with a sealing cover; in use, the operation part drives a traction rope to lift the lifting bucket to obtain resistance; for the resistance is gradually increased, the operation part cannot be pulled initially, and the tail section can acquire enough resistance; every person can reach own maximum limit, and device meets the physiological rule of the human body; moreover, people cannot be injured by water counterweight.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2015103801006, the application date is July 02, 2015, and the invention name is: counterweight device for strength gradient physical training device. technical field [0002] The invention relates to a physical training device, in particular to a counterweight device for a physical training device with gradually changing strength. Background technique [0003] In life, people participate in various sports and activities. In order to achieve good results and enhance their physical fitness, they need a lot of training, most of which belong to strength training, and the training items in terms of strength are mainly targeted. To implement the exercise strengthening of muscles in a certain area, many training equipment with different functions have been developed for this purpose. During the training, the strength of the muscles must be relied on to overcome the res...

Problems solved by technology

The resistance mechanism provided by existing training equipment generally adopts counterweights, and the operation part drives the traction rope to lift the counterweights to obtain resistance. This kind of resistance mechanism uses the number of counterweights to adjust the resistance, which is not fine enough to adjust, and The resistance is constant in the process of pulling and releasing, but affected by factors such as the angle of force applied when the human body moves, the limit of the force that a person can bear or release in each position during the movement is different, so this structure is against the law. This kind of physiological law, such as overloading at the beginning of the movement stroke under constant force, is very easy to strain, the end of the movement stroke has insufficient resistance, and insufficient training, and the adjustment of the weight block structure is also easy to hurt people, which still needs to be developed.
