Optical imaging lens

An optical imaging lens, comprising:

• a plurality of lens elements arranged in sequence along an optical axis from an object side to an image side, wherein
• each lens element has an object-side surface facing the object side and an image-side surface facing the image side,
• each lens element further comprises an optical portion for allowing an imaging ray to pass through and a mounting portion extending radially outwards from an optical boundary, and the optical boundary is a point at which the radially outermost marginal ray passing through a surface of the lens element intersects the surface of the lens element,
• the lens elements are embedded with each other and are integrally assembled through glue,
• for the lens elements between a first lens element counting from the object side towards the image side and a first lens element counting from the image side towards the object side, the object-side surface of the mounting portion has a first propping surface, a first inclined surface, and at least three glue storage regions, the first propping surface is perpendicular to the optical axis, and the first inclined surface is connected to the first propping surface and inclined relative to the optical axis,
• each glue storage region has a first flat surface and a second inclined surface, the first flat surface is perpendicular to the optical axis, the second inclined surface is connected to the first flat surface and inclined relative to the optical axis, and the glue storage regions do not contact one another,
• the image-side surface of the mounting portion has a second propping surface and a third inclined surface, the second propping surface is perpendicular to the optical axis, and the third inclined surface is connected to the second propping surface and inclined relative to the optical axis,
• each glue storage region is retracted a distance from the first propping surface and the first inclined surface, and
• the optical imaging lens satisfies the following:
• 1≤GS_AL/SP_AL≤3 and 5%≤(RGS2−RGS1)/RGS2≤30%, where GS_AL is an arc length of the glue storage region, SP_AL is an arc length of the first propping surface, RGS1 is a shortest distance from the optical axis to the second inclined surface, and RGS2 is a farthest distance from the optical axis to the first flat surface.
