[0032] Example
[0033] like Figures 1 to 8 As shown, according to an embodiment of the present invention, a folding picture frame is provided. The folding picture frame includes a picture frame body 1, which includes a main body layer 110, a display layer 140, two first pieces 121, two second pieces 131, two third pieces 122, two fourth pieces 132, two fifth pieces 123, two sixth pieces 133, and two seventh pieces 134.
[0034] Preferably, the frame body 1 of the folding picture frame is made of rigid cardboard and canvas layered together. The canvas sheet structure serves as the display sheet 140 of the folding picture frame, with the side facing away from the rigid cardboard serving as the display surface 140a. A preset pattern for display can be sprayed onto the display surface 140a using inkjet printing. Finally, the pattern sprayed onto the display surface 140a is protected by UV (ink dried and cured by ultraviolet light) printing. Alternatively, patterns can be directly drawn on the display surface 140a by hand. Multiple hollowed-out structural slots are stamped into the frame body 1 using a stamping process, and multiple V-shaped grooves are engraved on the surface of the rigid cardboard facing away from the canvas using a laser engraving process.
[0035] Specifically, such as Figure 1 , Figure 2 and Figure 8As shown, after laser engraving the side of the rigid cardboard in the frame body 1 formed by the stamping process away from the display sheet 140, the rigid cardboard is divided by multiple V-shaped grooves formed by laser engraving: the middle of the rigid cardboard forms a main body sheet 110 with an orthogonal projection of a rectangle, and each short side of the main body sheet 110 is sequentially connected with a first fold 110c, a first sheet 121, a third fold 121b, a third sheet 122, a fifth fold 122b, and a fifth sheet 123, and each fifth sheet 123 has a stamping process shape. Two first slots 120a are formed with a preset distance between them; each long side of the main body sheet 110 is sequentially connected with a second crease 110d, a second sheet 131, a fourth crease 131b, a fourth sheet 132, a sixth crease 132b, a sixth sheet 133, a seventh crease 133b, and a seventh sheet 134. Each fourth sheet 132 and its connected sixth sheet 133 have two second slots 130a formed by a stamping process and spaced at a preset distance between them. The first slots 120a and the second slots 130a correspond one-to-one.
[0036] Specifically, such as Figure 8 As shown, when the frame body 1 is in the unfolded state, the first surface 110a of the main body layer 110, the third surface 121a of the first piece 121, the fourth surface 131a of the second piece 131, the fifth surface 122a of the third piece 122, the sixth surface 132a of the fourth piece 132, the seventh surface 123a of the fifth piece 123, the eighth surface 133a of the sixth piece 133, and the ninth surface 134a of the seventh piece 134 overlap to form the bonding surface 1a of the frame body 1. Canvas can be glued to the bonding surface 1a to form the display layer 140 of the frame body 1. The side of the display layer 140 facing away from the first surface 110a of the main body layer 110 is the display surface 140a. The portion of the display surface 140a covering the first surface 110a of the main body layer 110 is used for inkjet printing, UV printing, or hand-painting to form a preset display pattern.
[0037] Specifically, such as Figures 3 to 7As shown, when the folding frame needs to be folded from the unfolded state to the folded state: the fifth piece 123 folds towards the second surface 110b of the main body piece 110 to 90° via its corresponding fifth crease 122b; the third piece 122 folds towards the second surface 110b of the main body piece 110 to 90° via its corresponding third crease 121b; the first piece 121 folds towards the second surface 110b of the main body piece 110 to 90° via its corresponding first crease 110c; and the main body piece 110, the first piece 121, the third piece 122, and the fifth piece 123, connected sequentially, enclose each other to form a cylindrical first support structure 120 with a rectangular cross-section; the seventh piece 134 folds towards the second surface 110b of the main body piece 110 to 90° via the seventh crease 133b; and the sixth piece 133 folds towards the second surface 110b of the main body piece 110 via the sixth crease 132b... The second surface 110b of the main sheet 110 is folded to 90°, the fourth sheet 132 is folded to 90° towards the second surface 110b of the main sheet 110 through the fourth crease 131b, and the second sheet 131 is folded to 90° towards the second surface 110b of the main sheet 110 through the second crease 110d. The second sheet 131, the fourth sheet 132, the sixth sheet 133 and the seventh sheet 134 connected in sequence surround each other to form a cylindrical second support structure 130 with a rectangular cross-section. The two first slots 120a on each first support structure 120 are respectively inserted into the corresponding second slots 130a on the adjacent second support structure 130, so that the two opposing first support structures 120 and the two opposing second support structures 130 surround each other, thereby forming a structural support for the second surface 110b of the main sheet 110. At this time, the folding frame is in a folded state, and in each of the first support structures 120 and any adjacent second support structures 130: the side of the third piece 122 facing away from its fifth surface 122a is attached to the sixth surface 132a of the fourth piece 132; the fifth piece 123 is inserted into the fourth piece 132 and the sixth piece 133 through the first slot 120a and the second slot 130a, so that the seventh surface 123a of the fifth piece 123 and the eighth surface 133a of the sixth piece 133 are perpendicular to each other; the ninth surface 134a of the seventh piece 134 is attached to the second surface 110b of the main body layer 110; to ensure the sturdiness of the folding frame in the folded state.
[0038] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0039] Compared with existing technologies, the folding picture frame provided in the above embodiments of this utility model directly applies the preset pattern to be displayed onto the display surface 140a of the canvas display layer 140 through inkjet and UV printing or hand-painting during manufacturing. By replacing the frame portion of traditional display paintings through unfolding and folding, production costs can be effectively reduced. When the folding picture frame is unfolded, it has a planar structure, and multiple folding picture frames can be stacked, thereby effectively improving space utilization and facilitating transportation or storage, thus effectively reducing transportation and storage costs. When the user needs to use the folding picture frame, it can be folded into a three-dimensional folded state. The unfolding and folding method of the folding picture frame provided in the embodiments of this utility model is easy to operate and effectively solves the problem of excessively high costs in the production, transportation, or storage of the frame portion of traditional display paintings.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
