Problems solved by technology

[0005] In the prior art, most of the pull-up assisting devices are elastic devices. With the movement of the body, the elastic force provided by the elastic device changes continuously, and cannot provide a constant auxiliary pulling force.
When the body position of the pull-up person rises for a certain distance, the power of the power-assisted device will decrease. At this time, the trainer may still not be able to complete the entire pull-up action, and a good training effect will not be achieved.
The content disclosed in CN 205683496U is still difficult to provide constant power assist or resistance, and the speed of the driving motor is difficult to coordinate with the speed of the trainer

Abstract

The invention discloses a chin-up training device. The device comprises a horizontal bar and an auxiliary constant force device, and the auxiliary constant force device comprises a supporting platform, a first hydraulic cylinder, second hydraulic cylinders and a counterweight device; a piston rod of the first hydraulic cylinder is fixedly connected with the supporting platform, and the first hydraulic cylinder drives the supporting platform to rise or fall; liquids in the first hydraulic cylinder and the second hydraulic cylinders are communicated with each other through a pipeline; piston rods of the second hydraulic cylinders are fixedly connected with the counterweight device. By means of the device, constant and continuous auxiliary force is provided in a chin-up process in assistance with safety and reliability.

Description

technical field [0001] The invention relates to the technical field of sports, in particular to a pull-up training device. Background technique [0002] Pull-ups are the most basic way to exercise the back, and they are also one of the important reference standards and items for measuring male physique. Pull-ups require men to have certain grip strength, upper body strength and shoulder girdle strength, and this strength must be able to overcome their own body weight to complete once. Pull-ups play an important role in the development of upper limb hanging strength, shoulder girdle strength and grip strength. It is one of the optional items for the physical education entrance examination, high school physical education examination and college students' physical fitness examination. Many beginners and those who lack exercise often have difficulty in completing the training due to weak back muscles and inability to continuously exert force in the forearm, and the training eff...
