Description

Folding Cheng Jujie mechanism Technical Field The utility model relates to the field of foldable containers, in particular to a foldable container structure. Background The container is a standardized container for containing, loading and transporting parts, and is subdivided into a box A, a box B, a box C and other types based on functional requirements. At present, the container box for containing parts is widely applied to warehouses, production lines and logistics links in factories. The C box is a common choice in the industry in production scenes with higher requirements on part bearing and transferring, such as welding factories, due to the advantages of structural stability and applicability. However, conventional C-boxes typically employ a one-piece fastening structure with the sidewalls between, and with the sidewalls and floor being welded or rigidly connected to form an integral unit. The structural design ensures the strength and stability of the C box in use, but has the problems that (1) the space utilization rate is not high, when empty boxes are stacked in a non-use state, the empty boxes cannot be compressed or folded, so that a large amount of storage and transportation space is occupied, and (2) the transportation cost is high, because the whole empty boxes are not detachable, the loading capacity per unit volume is low when the empty boxes are transported, the logistics transportation efficiency is difficult to promote, and further the logistics cost is increased. Disclosure of utility model The utility model aims to provide a folding Cheng Jujie structure to solve the problems of low space utilization rate and high transportation cost of a C box in the prior art. The foldable Cheng Jujie structure is characterized in that the front side and the rear side of the bottom plate are movably clamped with the long side plate, the left side and the right side of the bottom plate are connected with the short side plate through hinges, the long side plate is connected with the short side plate through bolts, the long side plate comprises a bearing main upright post, bearing auxiliary upright posts are arranged on the two sides of the bearing main upright post, the bottom plate comprises folding limiting sleeves corresponding to the bearing main upright post, the folding limiting sleeves are of a first groove structure, folding jackets corresponding to the bearing auxiliary upright posts are arranged on the two sides of the folding limiting sleeves, the folding jackets are of a second groove structure, the long side plate is clamped with the bottom plate through insertion fit between the bearing main upright post and the folding limiting sleeves, the bearing auxiliary upright post and the folding jackets, the bearing auxiliary upright post comprises a bolt cushion block at the top, the short side plate comprises a cylindrical cushion block hinge and a second limiting bolt corresponding to the bolt, the short side plate is inserted into the cushion block to be connected with the long side plate through the second limiting bolt, and the short side plate is connected with the bottom plate through the hinge. The principle of the scheme is that when the box is unfolded, the long side plates are in an upright state, the long side plates are inserted into the folding limiting sleeves of the bottom plate through the bearing main upright posts and the folding jackets of the bottom plate through the bearing auxiliary upright posts, the long side plates on two sides are fixedly clamped with the bottom plate, meanwhile, the short side plates are in an upright state and are connected with the bottom plate through the cylindrical hinge, the short side plates are inserted into the bolt cushion blocks of the adjacent long side plates through the second limiting bolts, and bolt locking between the short side plates and the long side plates is achieved, so that a complete C box structure is formed. When the folding is needed, the second limiting bolt is pulled out of the bolt cushion block to release the connection between the short side plate and the long side plate, then the short side plate is turned inwards and horizontally arranged on the left side and the right side of the bottom plate, then the long side plate is lifted upwards to enable the bearing main upright post to be separated from the folding limiting sleeve and the bearing auxiliary upright post to be separated from the folding sheath, then the long side plate is turned inwards and horizontally arranged on the front end and the rear end of the bottom plate, and finally the folding of the whole C box is completed. The technical prejudice that the folding structure is difficult to ensure the structural strength is broken through, and the folding structure is widely considered to influence the overall strength and the stability of the box body in the prior art, so that the service life and the safety are reduced.
