Adjustable electronic arm power exercising apparatus

Abstract

The invention provides an adjustable electronic arm power exercising apparatus which comprises an arm power spring, inner pipes, middle pipes and handle sleeves. The two middle pipes are fixedly inserted in the two outer ends of the arm power spring respectively. The middle pipes are movably inserted in the handle sleeves. The inner pipes are movably inserted in the middle pipes. The inner ends ofthe inner pipes can be inserted in or retreated out of the arm power spring. The outer ends of the inner pipes are fixedly connected with the outer ends of the handle sleeves so that the inner pipesand the handle sleeves can synchronously move along the middle pipes. The inner pipes and the handle sleeves are positioned in the middle pipes through adjusting mechanisms. In the adjustable electronic arm power exercising apparatus, when the inner pipes are retreated out of the arm power spring, the arm distance and torsion are adjusted by adjusting the relative positions of the handle sleeves and the middle pipes; when the inner pipes are inserted in the arm power springs, the deformation length of the arm power spring and the torsion are adjusted by adjusting the relative positions of theinner pipes and the arm power spring; in the use process of the arm power exercising apparatus, a counting mechanism can form or disconnect a circuit loop, and the automatic counting function is realized.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an adjustable electronic arm strength device. Background technique [0002] The arm strength machine is a common fitness equipment, which is used to exercise the arm muscles, mainly to exercise the arm and chest muscles, and to assist in exercising wrist strength. [0003] The torque of the arm force is determined by many factors, including the arm distance and the deformation length of the spring. The arm distance refers to the distance between the handle and the arm strength device. According to the principle of leverage, it can be inferred that the longer the arm distance, the smaller the torque. In the case of the same spring material and number of turns, the shorter the deformable length of the spring, the smaller the deformable range. Under the same deformation range, the shorter the deformable length of the spring, the greater the torsion force. [0004] The t...

AI Technical Summary

Problems solved by technology

[0004] The torque of the traditional arm strength machine is fixed, and it is impossible to adjust the torque according to the actual situation of the user, and the user's exercise effect is poor

Moreover, the traditional arm strength machine does not have a counting function, and the user needs to record the number of exercises by himself, which is inconvenient to use
