Description

Technical Field

[0001] This utility model relates to the field of eyeglass accessories technology, and in particular to an adjustable nose pad that accelerates sweating, prevents slipping, and reduces shock. Background Technology

[0002] In the field of eyeglass fitting technology, traditional nose pads, as the core component of the frame support system, generally adopt a composite structure design: soft PVC / silicone blades and built-in polycarbonate / metal-reinforced posts are injection molded and mechanically coupled to the arm via a post-box-type cable. In a typical implementation, Φ1.2-1.5mm transverse screw holes are opened on the side wall of the post box, and M1.4 micro screws are used to complete the three-point locking of the blade-arm assembly. Its structural advantages are high assembly efficiency and tensile strength of over 50N. However, this classic design has two major technical bottlenecks: First, the degree of freedom of adjustment is limited. Due to the rigidity constraint of screw locking, existing nose pads can only be discretely adjusted within a ±5° pitch angle range, and the horizontal displacement adjustment is less than 1mm, resulting in low fit rate for abnormal nasal bridge curvature (such as saddle nose or hump nose); Second, the smooth surface of the original nose pads is easily slipped by sweat. These defects seriously restrict the development of personalized eyeglasses, and there is an urgent need to develop a nose pad coupling solution with omnidirectional adjustment capability and improved durability.
