1. An optical imaging lens, comprising, sequentially from an object side to an image side along an optical axis, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, and a seventh lens element, each of the lens elements having an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through, wherein
a periphery region of the image-side surface of the first lens element is concave;
the second lens element has negative refracting power;
an optical axis region of the object-side surface of the third lens element is convex, an optical axis region of the image-side surface of the third lens element is concave, and a periphery region of the image-side surface of the third lens element is convex;
a periphery region of the image-side surface of the fourth lens element is convex;
an optical axis region of the image-side surface of the fifth lens element is concave;
an optical axis region of the image-side surface of the seventh lens element is concave;
wherein lens elements of the optical imaging lens are only the seven lens elements, and the optical imaging lens satisfies EFL/(G12+G67)≤5.600, wherein EFL is an effective focal length of the optical imaging lens, G12 is an air gap from the first lens element to the second lens element along the optical axis, and G67 is an air gap from the sixth lens element to the seventh lens element along the optical axis.
