Electromagnetic spring safety arm strength device

Abstract

The invention belongs to the field of fitness equipment and relates to an electromagnetic spring safety arm strength device. The device comprises a bent spring and handles mounted at the two ends of the bent spring, a protective layer is sleeved outside the handle, a plurality of ceramic piezoelectric patches are mounted between the protective layer and the handle, the plurality of ceramic piezoelectric patches are arranged outside the handle in the circumferential direction, a storage battery is embedded in the handle, the bent spring is made of a conductive material, the storage battery is electrically connected with the multiple ceramic piezoelectric patches and the bent spring, a cavity is formed in the handle, a balancing weight slides in the cavity in a sealed mode, the balancing weight slides horizontally in the axis direction of the cavity, the balancing weight is fixed to the side wall of the cavity through a reset spring, and a plurality of air channels are formed in the sidewall of the cavity. According to the fitness equipment, the stiffness coefficient of the bent spring can be changed according to different exercise periods so as to change the exercise intensity of auser, the fitness effect is better, the air channel can generate suction negative pressure on the hands of the user, and high safety performance is achieved.

Description

technical field [0001] The invention belongs to the field of fitness equipment, in particular to an electromagnetic spring safety arm strength device. Background technique [0002] With the improvement of living standards, fitness has become a daily compulsory course for people, and fitness equipment is becoming more and more diverse. Among them, arm strength equipment is a kind of exercise equipment for forearm wrist flexors, which is mainly used to exercise arm muscles. Constantly bending the spring achieves the purpose of exercising muscles, and it is often used to achieve the effect of bodybuilding and strengthening the arm. [0003] When the traditional arm strength machine is used, the strength required for bending is fixed, but in daily exercise, it is often necessary to warm up first, from shallow to deep.

Problems solved by technology

[0003] When the traditional arm strength machine is used, the strength required for bending is fixed, but in daily exercise, it is often necessary to warm up first, from shallow to deep. It is more difficult to use a higher strength arm strength machine for exercise at the beginning of the exercise , strenuous, easily lead to problems such as insufficient blood supply, dizziness, etc. If the strength of the arm strength machine is low, it is difficult to achieve a good fitness effect even if you exercise for a long time, that is, the arm strength machine with fixed strength cannot meet the normal exercise needs, and the arm strength machine is in use. During the process, when the spring retracts and returns to its original state, it is easy to pop up, causing the arm strength device to fall off, which in turn causes harm to the user or others, which is dangerous to a certain extent.
