Description

Technical Field

[0001] The utility model relates to the technical field of washers, in particular to a high-strength anti-fracture washer. Background Art

[0002] Washers are parts placed between the connected parts and nuts. They are generally flat metal rings used to protect the surface of the connected parts from being scratched by the nuts and to disperse the pressure of the nuts on the connected parts. Washers are divided into: flat washers-grade C, large washers-grade A and C, extra large washers-grade C, small washers-grade A, flat washers-grade A, flat washers-chamfered-grade A, high-strength washers for steel structures, spherical washers, conical washers, etc.

[0003] Excessive force during bolt installation may squeeze the gasket, causing deformation or even breakage. The existing patent application number is CN 202223600247.6, which discloses an anti-fracture gasket. The inner reinforcement ring and ribs together form a mesh structure to support the lower gasket and the upper gasket to improve the strength of the overall gasket. However, during use, the gasket is prone to shift relative to the bolt position, affecting the installation and connection effect.
