A kind of drawout cubicle, including frame, drawer unit and modularity locker. Drawer unit has X layers of drawer stacked on top of each other, and what frame is slideably installed along translation direction. Modularity locker includes X lock catch unit and a supporting element, and lock catch unit has Y rotating member and an at least fixing piece, and X and Y is positive integer, and rotating member quantity is at least two. Those rotating members sequentially push up bottom along long axis direction with supporting element and engage, and install what frame, and can linkedly pivot between what lock position and unlocked position, and fixing piece sets each drawer of what. When what latches position, rotating member latches what fixing piece； When what unlocked position, rotating member is separated with fixing piece. Thereby, through the design of modularity locker, to achieve the effect that reduce cost. In addition, this creation separately provides a kind of medical cart.一種抽屜櫃，包括框架、抽屜單元及模組化鎖扣裝置。抽屜單元具有X層相互疊置的抽屜，沿平移方向可滑動地裝設於框架。模組化鎖扣裝置包含X個鎖扣單元及一支撐件，鎖扣單元具有Y個轉動件及至少一固定件，而X與Y為正整數，轉動件數量為至少兩個。該些轉動件與支撐件沿長軸方向依序頂底接合，並裝設於框架，且能連動地於鎖扣位置與解鎖位置間樞轉，固定件設於每一抽屜。於鎖扣位置時，轉動件鎖扣於固定件；於解鎖位置時，轉動件與固定件分離。藉此，透過模組化鎖扣裝置的設計，以達到降低成本的效果。此外，本創作另提供一種醫療用推車。
