Abstract
The invention provides a folding storage device capable of being folded and unfolded in a linkage mode. The folding storage device comprises a middle telescopic unit, a top folding unit, a first sidetelescopic unit, a back folding unit, a second side telescopic unit and a bottom folding unit. The middle telescopic unit comprises a middle telescopic frame, a transverse supporting plate, a middle supporting column, a handle, a telescopic rack, a driving gear, a connecting rod and a third sliding block; and the top folding unit and the bottom folding unit are limited through a limiting structureon the middle telescopic frame. The first side telescopic unit comprises a first side extension frame, a first side supporting column and a ninth connecting rotating shaft. The second side telescopicunit and the first side telescopic unit are symmetrically arranged, the second side telescopic unit comprises a second side extension frame and a second side supporting column, and the back folding unit is rotationally connected with the first side supporting column through a ninth connecting rotating shaft and a connecting base corresponding to the ninth connecting rotating shaft. According to the device, the folding rate can be increased to reduce the occupied space, folding and unfolding can be conducted easily and rapidly, and rigidity is guaranteed.
Description
technical field [0001] The invention relates to a storage device, in particular to a foldable storage device that can be unfolded in conjunction. Background technique [0002] Lockers are indispensable daily office supplies. The use of a foldable structure can increase the space utilization of the lockers during transportation and storage, and has great practical application value. At present, most folding cabinets are composed of folding parts and supporting parts. The volume of the folding cabinet can be changed by dismantling the folding parts or reinforcing parts, and the mechanical properties of the folding cabinet are guaranteed by the supporting parts. [0003] There are various forms of storage cabinets in the prior art. For example, a patent document with application number 201520485192.X discloses a foldable cabinet, which changes the cabinet structure from a high cabinet to a low cabinet structure by folding; the application number is The patent document of 20162...
