This creates a kind of covering structure of fish jar,The fish jar includes that a bottom wall and plural number connect what bottom wall and define the side wall of an accommodating space,Covering structure mainly by plate body,Cover board,Pin connected assembly and stop part composition,Wherein plate body forms plural through-hole and at least one opening,Plate body furnishes the top edge of each side wall of what,What plate body and masking opening is then arranged in cover board,Pin connected assembly is arranged what plate body and cover board and is pivotally connected what plate body for cover board,Therefore cover board can pass through pin connected assembly and overturn to plate body,It can thereby allow feeding is main to clean through opening feeding or part,The stop part being arranged on what plate body can then limit cover board open state,It avoids the fish of raising from opening cover board because jumping credit and striking cover board and cause fish that may jump out of fish jar by opening to cause death,Prevent fish from jumping out by presentation mask effect at the top of fish jar using covering structure simultaneously.本創作一種魚缸之遮蓋結構，該魚缸包含一底壁及複數連接於底壁並且界定出一容置空間之側壁，遮蓋結構主要由板體、蓋板、樞接組件及擋止件組成，其中板體形成複數通孔以及至少一開口，板體擺設於各側壁之頂邊處，蓋板則設置於板體且遮蔽開口，樞接組件設置於板體及蓋板且供蓋板樞接於板體，因此蓋板可透過樞接組件對板體翻轉，藉此可讓飼主透過開口餵食或局部清潔，設置於板體上的擋止件則可限制蓋板開啟狀態，避免飼養的魚類因跳耀撞擊到蓋板而開啟蓋板造成魚類可能由開口跳離魚缸造成死亡，同時利用遮蓋結構讓魚缸頂部呈現遮罩效果防止魚類跳出。
