Embodiment

[0023] refer to Figure 1-5 , a spring arm force device for preventing rapid rebound, comprising a strong spring 1 and two holding rods 2, one side of the strong spring 1 is fixedly connected with a holding rod 2, and the other side of the strong spring 1 is fixedly connected with a safety Box 3, the side of the fuse box 3 away from the strong spring 1 is fixedly connected with another holding rod 2, the fuse box 3 and the holding rod 2 away from it are connected with a steel wire rope 4, and the inside of the fuse box 3 is fixed with a central axis 5. The central shaft 5 is rotatably connected with a cylinder 6 using bearings. The cylinder 6 and the central shaft 5 are jointly fixed with a torsion spring 7. One end of the steel wire rope 4 is fixed on the outer wall of the cylinder 6, and the other end of the steel wire rope 4 is connected to the holding The rod 2 is fixedly connected to ensure that the steel wire rope 4 can be wound on the cylinder 6 when the arm is bent;

Abstract

The invention discloses a spring arm power exercising apparatus capable of preventing rapid rebound. The spring arm power exercising apparatus comprises a strong power spring and two holding rods. Oneside of the strong power spring is fixedly connected with one holding rod, and the other side of the strong power spring is fixedly connected with a safety box. The side, away from the strong power spring, of the safety box is fixedly connected with the other holding rod. The safety box and the holding rod away from the safety box are connected with one steel wire rope. A central shaft is fixedlyarranged in the safety box. The spring arm power exercising apparatus has the advantages that when the arm power exercising apparatus is normally used, the strong power spring bends and restores at alow speed, when the elastic power of the strong power spring released by the corresponding holding rod makes the arm power exercising apparatus rapidly deform and restore, the steel wire rope pulls acylinder to rapidly rotate, air in a reaction box is pressed by a piston into an air bag, a rotating plate rotates to abut against a stop piece so as to make a rotating shaft immediately stop rotating, the steel wire rope cannot continue to be unwound from the cylinder, and it is avoided that the strong power spring continues to deform and body builders are hit and injured.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a spring arm strength device for preventing rapid rebound. Background technique [0002] With the continuous development of society, more and more people maintain a healthy body through fitness. Arm strength machines are widely welcomed by fitness enthusiasts because of their small size and unlimited fitness places; [0003] The traditional arm strength device only consists of a strong spring and a grip rod fixed at both ends. The arm strength is exercised by bending the strong spring with the arm. However, the bent strong spring has a large elastic potential energy, and there is a relatively obvious reverse elastic force. It is common for bodybuilders to lose their hands on the arm strength machine due to exhaustion and other situations, which may lead to dangerous situations. Contents of the invention [0004] The purpose of the present invention is to solve the pr...
