An improved arm strength device

Abstract

The invention provides an arm power device with the improved structure, and belongs to the technical field of fitness devices. The arm power device with the improved structure comprises a spring, a first handle and a second handle, wherein the first handle and the second handle are fixed at the two ends of the spring, the end of the first handle is sleeved with a first guiding ring, the first guiding ring is connected with the spring through a wire, the end of the second handle is sleeved with a second guiding ring, a power source and a counter are arranged in the second handle, the power source, the counter, the second guiding ring and the spring are connected in series through a wire, the counter can count one time after a loop is switched on, a protruding gas ejector pipe nozzle is also arranged at one end, connected with the spring, of the second handle, and faces the first handle, an air inlet is formed in other end of the second handle, an air fan is arranged in the gas ejector pipe nozzle, a switch is arranged on the second handle, the air fan, the power source and the switch are arranged in series, a temperature sensor is arranged on the spring, a controller is arranged in the second handle, and the controller is respectively and electrically connected with the temperature sensor and the air fan. The arm power device with the improved structure has the advantages that the time of bending in place in using can be judged, and the spring can be automatically cooled.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment and relates to an arm strength machine with an improved structure. Background technique [0002] When using the arm strength device, the purpose of exercising the arm muscles can be achieved by overcoming the spring force by bending the arm strength device forcefully. Usually, the strength is judged by the number of bends, and there are certain requirements for the curvature of the bend. The biggest bend is to make the handles at both ends touch together, but it will be troublesome to count people, and it is not easy to judge whether it is achieved. maximum bending. In addition, when the bending frequency is too fast, a large amount of heat will be generated in the middle of the spring, which not only brings the danger of the spring breaking and hurting people, but also easily burns people. Contents of the invention [0003] The purpose of the present invention is to solve the above ...
