The invention provides an underwater submersible vehicle hatch and an underwater sightseeing submersible vehicle with the hatch. The double-direction pressure-proof sealing of the hatch is realized. The hatch comprises a locking rotary table, a locking shaft, a pawl, a pawl limiting device, a ratchet wheel, an outboard wrench, a O-shaped sealing ring, a shaft sleeve, a hatch cover, a pawl torsional spring, a inboard locking wrench and a plurality of locking mechanisms, wherein each the locking mechanism comprises a locking connecting rod, a locking block and a column-shaped locking and limiting sleeve; the locking block at the end far away from the center of the locking connecting rod extends into a hatch fence, and then drives the locking rotary table to move towards the inward direction of a cavity, the center end of the locking connecting rod connected with the locking rotary table moves towards the inward direction of the cavity, and the locking and limiting sleeve closely joints the hatch cover and the hatch fence together as the fulcrum of the locking connecting rod by utilizing lever force, so that the pre-tightening effect and the sealing effect are achieved.
