1. An optical imaging lens, comprising 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 sequentially arranged along an optical axis from an object side to an image side, wherein each of the first lens element to the seventh lens element comprises an object-side surface facing the object side and allowing an imaging ray to pass through and an image-side surface facing the image side and allowing the imaging ray to pass through;
the first lens element has positive refracting power, and 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 image-side surface of the third lens element is convex;
an optical axis region of the image-side surface of the fourth lens element is concave;
a periphery region of the image-side surface of the fifth lens element is convex; and
the sixth lens element has negative refracting power;
wherein lens elements of the optical imaging lens are only the seven lens elements described above, and the following conditional formulas are satisfied:
3.800 mm≤(D11t31+ImgH)/Fno and 3.000≤Tavg2345/Tstd2345, wherein D11t31 is a distance from the object-side surface of the first lens element to the object-side surface of the third lens element on the optical axis, ImgH is an image height of the optical imaging lens, Fno is an f-number of the optical imaging lens, Tavg2345 is an average value of a thickness from the second lens element to the fifth lens element on the optical axis, and Tstd2345 is a standard deviation of the thickness from the second lens element to the fifth lens element on the optical axis.
