Description

technical field [0001] The invention relates to the technical field of ships, in particular to an embedded central fast opening and closing hatch cover. Background technique [0002] Hatch covers belong to the opening and closing equipment of ships, and have the functions of sealing, waterproof, and rust prevention. The hatch covers should not only ensure that waves and rainwater will not overflow into the cargo hold, but also have good sealing devices. At the same time, the hatch cover should be opened and closed quickly and easy to operate, which can not only ensure the safety of navigation, but also shorten the time for ships to stay in port as much as possible. However, the structure of the existing hatch covers is unreasonable, most of which are single-layer cover plate mechanisms, and its switch is unstable, thereby shortening the service life of the hatch covers. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies...
