The related a kind of storing apparatus of tool slide rail type reinforcing bottom of this creation system comprising one accommodates ontology, a reinforced structure and a fixed structure. Accommodating ontology has a bottom and a receiving portion； Reinforced structure has a stiffener and a pair of of sliding rail part； Stiffener links bottom and strengthens its structural strength, and two sliding rail parts link the opposite sides of what stiffener. Fixed structure makes between reinforced structure and bottom, can convert between what relative separation and opposite combination. Convert receiving ontology can between the fixed front position of the slide-in of what one and the fixed Hou position of a slide-in； And separation and opposite slide-in fixation are skidded off relatively externally to do respectively. Therefore this case have both mention drag dual-purpose Pet bag quite hommization, can separate completely mobile device weight is greatly decreased, reinforced structure can be completely disengaged and just what cleaning, separate in conjunction with it is convenient and securely with pet can be improved comfort level the advantages that.本創作係有關一種具滑軌式強化底部之容納裝置，其包括一容納本體、一強化結構及一固定結構。容納本體具有一底部及一容納部；強化結構具有一強化件及一對滑軌件；強化件連結底部而強化其結構強度，兩滑軌件連結於強化件之相對兩側。固定結構使強化結構與底部之間，可於相對分離與相對結合之間變換。使容納本體可於一滑入固定前位置與一滑入固定後位置間變換；而分別用以對外做相對滑出分離與相對滑入固定。故，本案兼具提拖兩用之寵物袋相當人性化、可完全拆離移動裝置大幅減少重量、可完全脫離強化結構而便於清洗、拆離結合方便且牢固與可提高寵物之舒適度等優點。
