Water-proof moisture-proof safe box

The utility model relates to a waterproof and moisture-proof safe, comprising a safe body (1) the front side of which is provided with a doorframe (2), a door plank (3) which is matched with the doorframe (2) and rotatablely assembled at one side of the doorframe (2), a latch (4) which is arranged at the back surface of the door plank (3) and a drive structure (5) which is arranged on the door plank (3) to drive the latch (4) to move; a sealing strip (6) which can closely contact with the edge of the rear surface of the door plank (3) is fixed around the doorframe (2). The sealing strip (6) is an elastic sealing strip and the head of the latch (4) is smallish. The part of the latch (4) head which can contact with an inside end (21) of the doorframe (2) is a slant (41). The tilt direction of the slant (41) is that: the slant is gradually away from the inside end (21) of the doorframe (2) from an inner end (412) to an outer end (411). In the process of gradual locking of the latch, the door plank is driven to compress the sealing strip. The sealing strip is compressed and deformed by the door plank in a state of complete locking, thus effectively ensuring sealing performance between the doorframe and the door plank.
