The invention provides a hatch cover which comprises a hatch cover body, a driving gear set, a driven gear set and a clamping connection piece. One side of the hatch cover body is rotationally connected with a hatch door through an opening and closing hinge set. The driving gear set is arranged in the middle of the hatch cover body through a rotating shaft. The driven gear set is arranged at the position, close to the hatch door, of the hatch cover body. The driving gear set and the driven gear set are rotationally connected through a rotating chain. The clamping connection piece is arranged at the position, close to the hatch cover body, of the hatch door. The head of the clamping connection piece is a clamping connection rod fixing block. The clamping connection piece is correspondingly connected with a wedge-shaped clamping connection rod of the driven gear set through the clamping connection rod fixing block. According to the technical scheme, air impermeability and integrality of the hatch cover and the hatch door can be improved.
