Problems solved by technology

The resistance required by existing arm strength devices is provided by the elasticity of materials such as springs or rubber. This type of arm strength device has a simple structure and is easy to use. The resistance can be selected from springs of different sizes. In addition, there is also a class of Hydraulic arm strength, which provides the resistance of the arm strength through hydraulic pressure, but this type of strength arm overcomes the hydraulic pressure to do work. Compared with the traditional spring type strength arm, the bending rate is slower when using the hydraulic strength arm, and the user experience is more comfortable. Intersection, so the spring arm is still widely used
[0003] However, when the current spring-type arm strength device is bent to the maximum extent, the force of the spring is also at the maximum state. The fast speed spring is easy to damage the vulnerable parts such as the user's jaw, teeth or fingers, which is more dangerous to use

Abstract

The purpose of the present invention is to provide a torsion spring type anti-rebound arm force device, which includes two arm levers, handles are arranged on the two arm levers and the ends away from the handle are hinged together, and the hinge shafts of the two arm levers are provided with There is a torsion spring; it also includes an arc-shaped hydraulic cylinder, and the left and right ends of the arc-shaped hydraulic cylinder are pinned together with the arm levers on both sides through safety bars; The hydraulic pressure slows down the rebound speed when the arm strength is out of control, so as to prevent the user from being hurt when the arm strength is out of control and quickly rebounds without affecting the user experience, and improves the safety of the arm strength.

Description

technical field [0001] The invention relates to the technical field of fitness equipment and sporting goods, in particular to a torsion spring type anti-rebound arm strength device. Background technique [0002] With the development of social economy and the improvement of people's living standards, the daily pursuit of Chinese people has gradually increased the demand for fitness. As a portable and cheap strength training equipment, arm strength machines are widely loved by the crowd, especially the young people. The resistance required by existing arm strength devices is provided by the elasticity of materials such as springs or rubber. This type of arm strength device has a simple structure and is easy to use. The resistance can be selected from springs of different sizes. In addition, there is also a class of Hydraulic arm strength, which provides the resistance of the arm strength through hydraulic pressure, but this type of strength arm overcomes the hydraulic pressure...
