AI Technical Summary
When the male and female buckles are connected, the support part of the female buckle is easily squeezed and cracked, leading to breakage and affecting the stability of the product.
A fracture-resistant hook and buckle was designed. By setting stress grooves and stress holes on the female buckle and setting limiting steps and deformation grooves on the connecting shaft of the male buckle, the support part is allowed to deform during connection, avoiding excessive stress that could lead to breakage. At the same time, support bars are set on the support part to increase strength.
This effectively prevents the female buckle support from breaking during connection, improves the hook's tensile strength and stability, and enhances the overall strength and durability of the product.
