The present invention provides a pet box assembly, which comprises a main body and a cover body covered thereon, wherein the periphery of their intersection is respectively protruded with columns at corresponding segments, such that the through hole kept at one end of a snap sheet in a predetermined shape may be guided by the columns of the aforementioned two members to be pivoted. Furthermore, the end of each pivoted snap sheet that is not pivoted is inwardly extended with a stopping portion, which is cooperated with an action end of a corresponding holding unit combined in a predetermined range with the main body that has been guided into for forming a temporary orientation limitation. Thus, the constructed pet box can easily achieve an expected and accurate positioning by a simple operation, or may be easily disassembled that the associated parts may be individually detached for application.一種寵物箱，是採以：在寵物箱含括的基礎本體、及上端覆設的蓋體交界周邊相應段落是各別延伸以凸柱，以允許預設形態的扣片一端保持的透孔可受到前述二構件的凸柱引入，使形成樞接狀態；另在每一被樞接的扣片位在非樞接一端是朝內延伸一截抵制部，以配合引入前述基礎本體在預設範圍結合的相應夾持單元一作用端、使形成一暫時方位限制；使構成的寵物箱可在簡便操作下達到預期的確切定位、或在輕易拆解即可將相關構件個別取下的應用。
