1. An optical imaging lens assembly, sequentially comprising from an object side to an image side along an optical axis:
a first lens with a positive refractive power;
a second lens with a refractive power;
a third lens with a refractive power;
a fourth lens with a refractive power;
a fifth lens with a refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface;
a sixth lens with a positive refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface;
a seventh lens with a negative refractive power;
wherein TTL is an on-axis distance from an object-side surface of the first lens to an imaging surface, and ImgH is a half of a diagonal length of an effective pixel region on the imaging surface, and TTL and ImgH satisfy: TTL/ImgH<1.25.
