Rectangular anti-fatigue spring capable of releasing stress

Abstract

The utility model provides a rectangular anti-fatigue spring capable of releasing stress, which relates to the technical field of rectangular springs and comprises a spring body. The spring body is provided with a bearing guide rod in the vertical direction, a limiting annular plate is arranged on the outer circumference of the bottom of the bearing guide rod, a fixing stud is arranged on the end face of the bottom of the bearing guide rod, an anti-disengaging stud is arranged on the end face of the top of the bearing guide rod, and an insertion hole penetrating front and back is formed in the middle of the anti-disengaging stud of the bearing guide rod. The outer circumference of the bearing guide rod is sleeved with a rectangular-section spring in the vertical direction, the rectangular-section spring is of a hollow structure, stress distribution is more uniform through round corner treatment of the rectangular-section spring, the situation that local stress is too large is reduced, and the hollow structure of the rectangular-section spring enables materials to have more buffering space in the deformation process. The problems that four corners of a rectangular section are prone to stress concentration in the spring deformation process, local stress cannot be conveniently reduced through a round corner structure and an internal hollow structure, and space is provided for stress release are solved.
