[0019] This application provides a pulp-supported photo frame; please refer to [link / reference]. Figure 1 and Figure 2The pulp-supported photo frame 10 includes a front support 100 and a rear support 200. The front support 100 has a rectangular window 111 for displaying the photo. The front support 100 and the rear support 200 are detachably connected by a snap-fit ​​structure 300. Both the front support 100 and the rear support 200 have a pulp molding structure, that is, pulp is injected into a mold and then dried and shaped. Of course, in subsequent structures related to this application, after the pulp body is molded, it will be further combined with stamping to form a precise snap-fit ​​structure and other structures.

[0020] The front support 100 has a window support 110 stamped on the side near the rear support 200. The window support 110 has a rectangular window 111. The wall of the window support 110 near the rear support 200 forms a retaining wall 112, which surrounds the rectangular window 111. When the front support is installed on the rear support, the retaining wall 112 holds the photo album or picture book against the rear support. The rear support 200 has a first rectangular ring reinforcing boss 210 and a plurality of second rectangular ring reinforcing bosses 220 stamped on the side away from the front support 100. The plurality of second rectangular ring reinforcing bosses 220 are all located inside the first rectangular ring reinforcing boss 210. The first rectangular ring reinforcing boss 210 has a first U-shaped reinforcing groove 211 formed on the side of the rear support 200 near the front support 100, and the plurality of second rectangular ring reinforcing bosses 220 have second U-shaped reinforcing grooves 221 formed on the side of the rear support 200 near the front support 100. In this application, the rectangular ring can also be understood as a rectangular racetrack shape, or a rectangular ring, or a rectangular frame, or a U-shape.

[0021] The pulp-based photo frame provided in this application includes a front holder 100 and a rear holder 200. Both the front holder 100 and the rear holder 200 have a pulp molding structure. Compared to traditional plastic products with degradation cycles of decades or even centuries, this application, due to its pulp molding structure, uses pulp holders made from natural plant fibers, which can rapidly degrade into carbon dioxide and water in the natural environment, reducing plastic pollution at the source. The degradation cycle of the pulp holder is 6-12 months, thus its environmental friendliness is relatively good. Moreover, the raw material cost of the pulp holder is more than 30% lower than that of biodegradable plastics. The front holder 100 and the rear holder 200 are detachably connected by a snap-fit ​​structure 300, which is convenient for assembly and disassembly. The snap-fit ​​combination of the front and rear holders allows for easy replacement of drawing paper. The production process of the pulp holder in this application is mainly physical processing, without the need for chemical treatment, which can reduce carbon emissions by more than 25%. The front and rear holders can be stacked separately, which can reduce transportation costs and storage space. In addition, this application has a window support platform stamped on the front support, and a first rectangular ring reinforcing boss and multiple second rectangular ring reinforcing bosses stamped on the rear support. The U-shaped reinforcing groove forms a three-dimensional support network, which effectively disperses stress, improves structural strength, and makes the structure durable, sturdy and non-deformable during use.

[0022] In one embodiment, the four edges of the front support 100 and the rear support 200 are provided with matching snap-fit ​​structures 300, including an elastic snap tongue 310 provided in the front support 100 and a snap groove 320 provided in the rear support 200. When the elastic snap tongue 310 engages with the snap groove 320, the front support and the rear support are fixed together. Disassembly is achieved by forcefully squeezing the elastic snap tongue 310 out of the snap groove 320. For example, four elastic snap tongues 310 are provided, symmetrically arranged in pairs. The symmetrical snap-fit ​​on all four sides ensures uniform force distribution and avoids cracking on one side. The elastic snap tongues provide 0.5-1.2mm of deformation compensation space.

[0023] In one embodiment, the circumferential edge of the front support 100 protrudes towards the rear support 200 to form a cover edge 120; the circumferential edge of the rear support 200 has a cover groove 230 towards the front support 100, the inner sidewall of the cover edge has an elastic latch 310, and the sidewall of the cover groove 230 has a slot 230. The cover edge 120 of the front support 100 fits into the cover groove 230 of the rear support 200. This cover edge-cover groove nested structure further improves the overall structural strength and ensures the product does not deform.

[0024] In one embodiment, the rear support 200 has a hanging hole 212 on the side away from the front support, and a hook is also provided on the hanging hole 212. Thus, by providing the hanging hole and hook, hanging is convenient. For example, the hanging hole 212 is provided on the first rectangular ring reinforcing boss 210. Alternatively, the hanging hole 210 is provided on each of the four opposite sides of the first rectangular ring reinforcing boss 210, thus allowing for convenient hanging from any angle as needed.

[0025] In one embodiment, the front support has a resilient latch with a reinforcing rib at its root on its cover edge; the rear support has a corresponding dovetail-shaped latch in its cover groove. Thus, the reinforcing rib extends the lifespan of the latch, and the dovetail-shaped latch improves positioning accuracy.

[0026] In one embodiment, the front support and the rear support are 3-5mm thick, and the overall shape of the front support and the rear support is rectangular, with rounded corners at their edges. This 3-5mm thickness achieves a balance between strength and weight, and the rounded corners reduce the risk of stress concentration.

[0027] In one embodiment, both the outer surfaces of the front support and the rear support are provided with a moisture-proof layer, which can further improve the overall moisture-proof effect and service life.

[0028] In one embodiment, both the front and rear supports are made of plant fibers. For example, in practical applications, the picture frame uses natural plant fiber corrugated paper scraps as raw materials. Preferably, a 5% waterproofing agent can be added during the pulping process to further enhance the moisture-proof effect, ensuring that it will not deform even after prolonged use in the natural environment. Then, through molding, drying, and shaping processes, a semi-finished picture frame pulp support is produced. The viewing area and frame are trimmed through an edge-cutting process to make its appearance more aesthetically pleasing. Finally, fixing holes are cut at the four corners of the lower support to produce the finished picture frame pulp support.

[0029] In one embodiment, the viewing window support is tilted inward along the axis of the rectangular viewing window away from the front support, with an inclination angle of 85 degrees; for example, the abutment wall is provided with alternating V-shaped stress grooves and arc-shaped protrusions, forming a dynamic buffer structure. Thus, the 85° tilt angle makes photo installation and positioning more convenient, and the combination of V-shaped grooves and arc-shaped protrusions can absorb some assembly stress and improve service life.

[0030] The pulp-based photo frame provided in this application includes a front tray and a back tray, both of which have a pulp molding structure. Compared to traditional plastic products with degradation cycles of decades or even centuries, this application, due to its pulp molding structure, uses pulp trays made from natural plant fibers that can rapidly degrade into carbon dioxide and water in the natural environment, reducing plastic pollution at the source. The degradation cycle of the pulp tray is 6-12 months, thus exhibiting relatively better environmental performance. Moreover, the raw material cost of the pulp tray is more than 30% lower than that of biodegradable plastics. The front tray and the back tray are detachably connected by a snap-fit ​​structure, making disassembly and assembly convenient. The snap-fit ​​combination of the front and back trays allows for easy replacement of drawing paper. The production process of the pulp tray in this application is mainly physical processing, requiring no chemical treatment, thus reducing carbon emissions by more than 25%. The front tray and back tray can be stacked separately, reducing transportation costs and storage space. In addition, this application has a window support platform stamped on the front support, and a first rectangular ring reinforcing boss and multiple second rectangular ring reinforcing bosses stamped on the rear support. The U-shaped reinforcing groove forms a three-dimensional support network, which effectively disperses stress, improves structural strength, and makes the structure durable, sturdy and non-deformable during use.

[0035] 4. Detachable and easy to assemble: The upper and lower supports use a snap-fit ​​design, allowing for easy replacement of drawing paper;

[0036] 5. Reduce carbon emissions: The production process of pulp trays is mainly physical processing, without the need for chemical treatment, which can reduce carbon emissions by more than 25%;

[0037] 6. The upper and lower trays can be stacked separately, which can reduce transportation costs and storage space.

[0038] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
