Description

Folding display rack Technical Field The utility model relates to the technical field of exhibition and demonstration, in particular to a folding exhibition frame. Background The display frames of various types are flexibly and rapidly built in occasions such as conferences, exhibitions and displays, and are used for displaying and propaganda of commodities, so that the enterprises are more and more loved. The exhibition cloth frame, the exhibition lamp box and the exhibition promotion table are exhibition appliances which are very wide in application, and the exhibition cloth frame, the exhibition lamp box and the exhibition promotion table are mainly structurally characterized in that the exhibition cloth frame, the lamp light and other components can be temporarily assembled to form a large-sized exhibition curtain, and the exhibition cloth frame, the exhibition lamp box and the exhibition promotion table can be independently placed to form a small-sized propaganda column. The patent document with the bulletin number of CN216353185U discloses a folding display lamp box, long section bars and short section bars are connected through rotation, and the length of the long section bars is greater than twice the length of the short section bars, so that folding storage of the lamp box is realized. In this patent, the length of the long profile must be greater than twice the length of the short profile, which places a large limit on the size of the folding display rack. The length of the display rack needs to be increased simultaneously when the height is increased, so that the display rack cannot meet the use requirements of different scenes. Disclosure of utility model The utility model aims to solve the technical problem that the folding display rack is difficult to fold in the prior art, and provides the folding display rack which is not limited by the length and the height dimension and is convenient to fold and store. The technical scheme includes that the folding display frame comprises a pair of long frames and a pair of short frames, wherein the long frames comprise a first frame and a second frame, the first frame is hinged with the short frames through a first corner connecting piece, the second frame is hinged through a second corner connecting piece, the first frame and the second frame are hinged through a middle corner connecting piece, the two middle corner connecting pieces have a height difference in the vertical direction, the second frame is folded inwards on the short frames through the second corner connecting piece, and the first frame is folded downwards on the second frame through the first corner connecting piece and the middle corner connecting piece. According to the folding display rack, the middle corner connecting pieces of the pair of long frames are arranged in a staggered mode in the vertical direction, so that the pair of long frames form a Z-shaped folding storage structure in the folding process, the interference of the long frames during folding is avoided, and folding storage is facilitated. Further, the length of the second frame is smaller than the length of the short frame, and the length of the first frame is larger than or equal to the length of the short frame. Thus, a folding structure in which the short frame, the second frame, and the first frame are stacked in order can be formed. Further, the first corner connector, the second corner connector and the middle corner connector are arranged at intervals along the inward direction of the folding display frame in the folded state. Further, in order to make folding exhibition frame keep stable under the expansion state, middle corner connecting piece includes first grafting body and second grafting body, first grafting body and second grafting body insert in first frame and the second frame, have the boss on the first grafting body, have the recess on the second grafting body, when folding exhibition frame expands, boss and recess butt. Further, in order to avoid having the clearance between the first frame and the second frame under the expansion state, after first frame and the second frame expand, first frame and second frame shield first grafting body and second grafting body, just first frame and second frame butt joint form a plane to make only have a linear gap between first frame and the second frame. Further, in order to enable the first frame and the first frame to be folded relatively and no gap exists between the first frame and the second frame after being folded, connecting plates which are alternately arranged are connected between the first plug-in body and the second plug-in body, the middle parts of the connecting plates are connected through a first rotating shaft in a rotating mode, one end of each connecting plate is connected with the first plug-in body or the second plug-in body through a second rotating shaft in a rotating mode, and the other end of each connecting plate slides in the first plu
