This paper introduces a weather tight hatchcover for cargo ships that can be opened by single pull,lift off and meet part opening requirements.This design cleverly uses connecting chains,compacters,adaptors,limiters,eccentric wheels,guide wheels and other mechanical components to cooperate with each other through mechanics and motion trajectory analysis to realize a variety of schemes for opening the hatchcover.This design can meet the needs of different shipowners,different users,different ship types,different positions to open the hatchcover.
