The invention belongs to the technical field of fitness equipment, and particularly relates to a cam hydraulic energy consumption type safe arm strength exercising device. The cam hydraulic energy consumption type safe arm strength exercising device comprises a hydraulic cylinder, wherein a piston is arranged in the hydraulic cylinder, hydraulic oil is contained in the hydraulic cylinder, the left side of the hydraulic cylinder is provided with an upper flow channel hole, the right side of the hydraulic cylinder is provided with a lower flow channel hole, the left flow channel hole is provided with a one-way valve outside the hydraulic cylinder, the right flow channel hole is provided with an adjustable throttling valve outside the hydraulic cylinder, a hydraulic rod is arranged at the lower part of the piston, a pressure plate is arranged below the hydraulic cylinder, the lower end of the hydraulic rod penetrates through the bottom surface of the hydraulic cylinder to be connected with the pressure plate, a compression spring is arranged between the hydraulic cylinder and the pressure plate, a notch is formed in each of the left side and the right side of the pressure plate, each of the left side and the right side of the lower end surface of the hydraulic cylinder is provided with a supporting rod, each supporting rod is clamped in a notch, a hinge rod is arranged in each hinge hole, a cam is arranged in each hinge groove, each cam is hinged to the corresponding supporting rod through the corresponding hinge rod, and a handle is arranged at the lower end of each cam. The invention aims at solving the problems that the safety is poor and the adaptation range is narrow due to the structure defects of the existing arm strength exercising device.
Description
technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a cam hydraulic energy consumption safety arm strength device. Background technique [0002] The arm strength device in the fitness equipment usually adopts the spring as the reaction force element. The body-builder makes the spring bend and deform by manipulating the arms at both ends of the spring, and at the same time, the reset force of the spring exerts a reaction force on the user's arm muscles, so as to achieve the purpose of exercising the arm muscles. [0003] There are following problems in the traditional arm strength machine: [0004] 1. Since the spring stores elastic potential energy after deformation, the potential energy tries to overcome the muscle force of the bodybuilder's arm. If the fitness personnel operate improperly or do not have enough control ability, the spring will reset quickly, which will easily lead to injury accidents. [...
