Operation keyboard with waterproof anti-smashing structure

The invention relates to an operation keyboard with a waterproof anti-smashing structure. The operation keyboard comprises a printed circuit board, an air guiding layer, a metal reed, a top layer thin film, an inserted connection piece and an indicating film. The printed circuit board is a double-face board, the inserted connection piece is welded to the printed circuit board, the air guiding layer comprises a thin film coated with double-faced adhesive tape, one face of the air guiding layer is pasted with the printed circuit board, the other face of the air guiding layer is pasted with the top layer thin film to package and fix the metal reed, the air guiding layer is provided with an air guiding groove and a fake key, and the indicating film is placed on the top layer thin film. By means of the operation keyboard, the fake key is arranged on the air guiding layer, and sufficient air exchange space is provided when multiple keys are operated; a thickened thin film is arranged on the periphery of the top layer thin film, and looseness of the double-faced adhesive tape on the peripheral thin film due to keyboard middle protruding caused by an uneven keyboard metal lining plate is avoided; a protruding protection layer with elasticity is additionally arranged on the indicating film, the keyboard is prevented from being damaged by external sharp mechanical stress, the keyboard smashing-preventing and anti-smashing reliability is improved, and the operation keyboard has the advantages of being convenient to install, maintain and use and the like.
