The new design designs the connector between the cover plate and the side door as a combined double-axis hinge to ensure that the cover plate and the side door have sufficient movement, ensure that the cover plate opens and closes smoothly, and facilitate the turnover box to be locked on various uneven grounds, but the device still has room for optimization.

[0004] The existing devices mainly use side panels and bottom panels of fixed heights to form a box body, which makes it difficult for some devices to fold and retract some side panels, resulting in inconvenience in stacking the lower layer of beverage bottles inside the box body. At the same time, some liquid turnover boxes are equipped with top covers, which makes it difficult for some devices to quickly limit the top covers through locking mechanisms, resulting in some devices being difficult to protect the beverage bottles inside the box body, reducing the working efficiency and practicality of the devices. Therefore, in order to solve the above problems, a liquid turnover box that is easy to lock the top cover is proposed. Utility Model Content
