The invention discloses a deep sea bionic pressureproof shell. An axial-symmetry eggshell-shaped structure with the length of L, the width of B and the turning radius of R(x) is formed by a left end socket, a right end socket and a middle shell, wherein the thickness t2 of the middle shell is of an equal-strength variable-thickness structure, the thickness t1 of the left end socket and the thickness t3 of the right end socket are respectively of an equal-thickness structure, the left end socket and the middle shell are fixedly connected, and the right end socket and the middle shell are connected by a flange bolt or a movable hatch cover with a seal ring. The deep sea bionic pressureproof shell has good mechanical properties, in-shell space utilization rate, hydrodynamic characteristics and passenger comfort, and comprehensive improvement on safety, carrying capacity, mobility and diving time of a diving device is facilitated; meanwhile, the weight of the pressureproof shell is lightened, the reserve buoyancy of the pressureproof shell is increased, and the processing and manufacturing difficulty and cost are reduced.
