Physical training device counterweight apparatus with strength gradually changed

Abstract

The present invention discloses a physical training device counterweight apparatus with strength gradually changed. The physical training device counterweight apparatus with the strength gradually changed is characterized in that the physical training device counterweight apparatus comprises a liquid storage barrel and a pull-through barrel; the pull-through barrel is inverted in the liquid storage barrel with the bottom upward; the central position of the bottom of the pull-through barrel is connected with a traction portion; the bottom of the pull-through barrel is provided with an exhaust vent; and the exhaust vent is provided with a seal cover. When the physical training device counterweight apparatus is used, an operation portion drives a pulling rope to pull the pull-through barrel so as to obtain resistance, due to the fact that the resistance is gradually increased, muscle cannot be strained at the beginning, enough resistance can also be obtained at the end, everyone can reach the maximum limit, human body physiological law is satisfied, and people cannot be hurt by water counterweight.

Description

technical field [0001] 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 [0002] 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 resistance of the training equipment to move, and the repeated exercise will strengthen the muscle strength, so as to achieve the purpose of training. The resistance mechanism provided by existing training equipment generally adopts counterweights, and the operation par...

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.
