Cupboard with up-down louvered door and balance system

摘要

A cupboard has an up-down louvered door. Wherein the door comprises a plurality of louvers, and a lift rack in which the louvers are configured. When people need to open the door, the lift rack lifts and folds up, causing the louvers to fold up, and thus the door is opened; and when people need to close the door, the lift rack descends and extends, causing the louvers to extend, and thus the door is closed. The door can open adequately so as to facilitate taking out/putting in articles. No more space is occupied while opening the door, and the door is safe when closing. A small driving force can open/close the door, and the cupboard features easy operation, long lifetime, low cost and good stability.
