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

[0003] At present, since a large space needs to be reserved when opening the movable hatch cover, it will occupy a large area in actual use, which is not conducive to the use of the ship. In addition, it has no fixed structure. When the seafarers enter and exit, the hatch cover is often affected by the ship to reduce the width of the exit. If they are not careful, the seafarers will hit their heads on the hatch cover, which is very dangerous. Although the folding hatch cover occupies a smaller area, it will block part of the exit after folding, affecting the crew's entry and exit of the cabin. At the same time, the traditional hatch cover lock requires a lot of force to use, which is very inconvenient. Summary of the invention
