Fuel inlet structure for vessel

A fuel inlet structure comprising.

• a hollow cylindrical casing;
• a plug adapted to close said casing, said plug comprising a horizontal cover plate fitting over said casing, a center hole at the center of said cover plate, and a hollow cylindrical plug body perpendicularly downwardly extended from a bottom side of said cover plate around said center hole, said plug body having a horizontal bottom wall;
• a movable handle mounted in said plug body and vertically movable between a received non-operative position where said movable handle is received inside said plug body and maintained in flush with a top surface of said cover plate, and an extended operative position where said movable handle has a part extended out of said center hole of said plug for gripping by hand to remove said plug from said casing;
• spring means mounted on the bottom wall of said plug body to support said movable handle in said extended operative position
• a locating plate fixedly vertically mounted in said plug body at one side, said locating plate defining a longitudinal track, said track comprising a longitudinally extended deep groove, and a shadow groove, said shadow groove comprising an invertedly disposed U-shaped upper positioning section corresponding to an upper part of said center groove, a substantially V-shaped lower positioning section downwardly extended from one end of said upper positioning section corresponding to a left lower part of said center groove, and a substantially V-shaped lower guide section upwardly extended from one end of said lower positioning section corresponding to a right lower part of said center groove and connected to one end of said upper positioning section opposite to said lower positioning section;
• and
• a coupling member fixedly fastened to one side of said movable handle and adapted to guide movement of said movable handle along said track and to selectively lock said movable handle between said extended operative position and said received non-operative position, said coupling member comprising a guide disk coupled to the center groove of said track and adapted to guide vertical movement of said movable handle along said track, and a butterfly control block fastened pivotally with said guide disk and adapted to control positioning of said coupling member in said track;
• wherein when the user pressed said movable handle downwards from said extended operative position toward said received non-operative position, said butterfly control block is stopped in said lower positioning section to lock said movable handle in said received non-operative position;
• when the user pressed said movable handle again, said butterfly control block is disengaged from said lower positioning section and moved along said lower guide section into said upper positioning section to lock said movable handle in said extended operative position.
