[0002] The hatch cover is one of the important components on a ship. It belongs to the opening and closing equipment of the ship and has functions such as sealing, waterproofing, and rust prevention. The hatch cover should not only ensure that waves and rainwater do not flood into the cargo hold and has a good sealing device. At the same time, the hatch cover should also be opened and closed quickly and operate simply, which can not only ensure navigation safety but also shorten the ship's port stay time as much as possible.

[0003] When the existing hatch cover is opened and closed, generally, it is necessary to rotate the switch for controlling the telescopic movement of the locking tongue, and then pull the handle on the hatch cover. In case of an emergency, the extra steps will cause a waste of time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a ship hatch cover to solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A ship hatch cover, including a hatch cover mounting seat and a hatch cover. The hatch cover is rotationally connected to the hatch cover mounting seat through a rotating shaft. A return spring is sleeved on the rotating shaft. The hatch cover is composed of a hatch cover main body and a hatch cover main body locking mechanism installed on the hatch cover main body. The hatch cover main body locking mechanism is composed of a locking tongue, a locking tongue driving plate, and a hatch door handle. The locking tongue driving plate has a "U" - shaped structure and is inserted into the hatch cover main body from below, and the locking tongue driving plate can slide up and down. A row of driving teeth is fixedly arranged on the lower outer sides of the side plates on both sides of the locking tongue driving plate. A locking tongue is arranged on each side of the locking tongue driving plate. The locking tongue is fixed to the hatch cover main body through a connecting seat, and the locking tongue is rotationally connected to the connecting seat. A driven tooth that meshes with the driving teeth is fixedly arranged on the side of the locking tongue close to the locking tongue driving plate. The hatch door handle is located above the hatch cover main body, and the hatch door handle is fixedly connected to the locking tongue driving plate. A locking frame that cooperates with the locking tongue is arranged on the inner top of the hatch cover mounting seat.

[0006] Preferably, an inclined smooth surface is arranged on the side of the locking tongue far from the locking tongue driving plate, and an inclined transition surface is opened at the position of the locking frame that cooperates with the locking tongue.

[0007] Preferably, two columnar springs are arranged between the locking tongue driving plate and the hatch cover main body, and protrusions for positioning the columnar springs are arranged on both the locking tongue driving plate and the hatch cover main body.

[0008] Preferably, a lower limit plate is fixedly arranged at the lower part of the inner side surfaces of the side plates on both sides of the locking tongue driving plate, and an upper limit plate is fixedly arranged at the upper part of the inner side surfaces of the side plates on both sides of the locking tongue driving plate.
