Description

Technical Field

[0001] This application belongs to the field of photo frame technology, and in particular relates to a paper composite photo frame. Background Technology

[0002] In existing technologies, the back support structure of a picture frame is usually integrated with the frame body, for example, by hinges, glue, or a one-piece molding process. While this design has the advantages of convenient assembly and low cost, it reveals significant drawbacks when using paper materials.

[0003] The limited strength and toughness of paper materials result in poor support from back supports, especially under frequent use or when subjected to external forces, making them prone to breakage. For example, the back supports of traditional cardboard photo frames are foldable structures formed by cutting lines, but the tear resistance of paper materials is insufficient, and fatigue fractures easily occur at the cutting lines after long-term use, causing the photo frame to lose its upright support.

[0004] Furthermore, once the back support of existing paper photo frames is damaged, the entire frame body often needs to be replaced, as the back support component cannot be replaced individually. This results in the entire frame being discarded, leading to resource waste and increased usage costs, thus requiring improvement. Utility Model Content

[0005] The purpose of this application is to provide a paper composite photo frame that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a paper composite photo frame, comprising:

[0007] The picture frame itself;

[0008] Back support, used to support the picture frame body;

[0009] Creases are provided on the back support;

[0010] Both the back support and the frame itself are made of paper, and the back support can switch between an unfolded state and a supported state through the fold lines.

[0011] In this paper composite photo frame, both the frame body and the back support are made of paper, meeting the requirements for environmental friendliness and low cost. The back support allows for switching between an unfolded and supported state via fold lines, changing the traditional fixed design where the back support and body are integrated. This switchable design facilitates both production and transportation. The frame remains unfolded during transport, while the user can fold it into a supported state, avoiding the breakage problem at the folded section caused by rigid connections in existing technologies.

[0012] Furthermore, the back support can be directly connected to the frame body or connected via double-sided tape. When the back support is damaged, it can be replaced separately without discarding the entire frame, thus solving the resource waste problem of replacing the entire frame when the back support of existing paper frames breaks. The frame body is used to hold the photo, while the back support provides structural support, clearly defining their respective functions.

[0013] Furthermore, the back support is trapezoidal in shape when it is in the unfolded state.

[0014] When unfolded, the back support is trapezoidal in shape. By utilizing the trapezoidal structure's narrower top and wider bottom, the contact area between the back support and the placement surface is increased, improving stability during support. Compared to the rectangular or triangular support structures used in ordinary paper photo frames, the trapezoidal structure can more evenly distribute the weight of the frame and the photo, reducing the risk of tipping over due to uneven stress and solving the problem of poor support performance of traditional paper materials.

[0015] Furthermore: the fold lines include:

[0016] Longitudinal creases are distributed parallel to each other in the vertical area of ​​the back support, dividing the back support into the side area and the support area along the vertical direction;

[0017] The horizontal creases are distributed horizontally in the middle of the back support, dividing the back support into a contact area and a reinforcement area in the horizontal direction;

[0018] The vertical creases and horizontal creases intersect perpendicularly.

[0019] The fold lines include both longitudinal and transverse folds that intersect perpendicularly. This intersecting design divides the back support into different functional areas, making its structural layout more rational. The perpendicular distribution of the longitudinal and transverse folds guides the back support to deform along a preset trajectory during folding, avoiding structural damage caused by arbitrary deformation due to unclear folding direction.

[0020] Furthermore, the longitudinal crease extends from the upper edge of the trapezoid to the lower edge, and the longitudinal crease does not penetrate the back support. It folds backward along the longitudinal crease to form a side area for supporting the back support when standing.

[0021] The longitudinal crease extends from the upper edge of the trapezoid to the lower edge without penetrating the back support, thus preserving the overall continuity of the back support and avoiding the defects of through creases or tear lines that are prone to breakage. The non-penetrating design ensures that some material remains connected at the crease during folding, enhancing the tear resistance of the crease area and extending the service life of the back support.

[0022] Meanwhile, the side area formed by folding backward along the longitudinal crease, through the combined effect of the two side areas, can improve the overall standing stability of the picture frame, effectively avoiding the problems of poor support and easy tipping caused by the single support surface of traditional paper back support.

[0023] Furthermore, the lateral crease is located in the middle of the back support, with its lower part connected to the back support and its upper part separated from the back support. The middle part is a horizontal crease, and the upper part can be folded inward along the horizontal crease. The lower part forms a contact area, and the upper part forms a reinforcement area for supporting the overall structure of the back support.

[0024] The horizontal crease is located in the middle of the back support. Its lower part connects to the back support, while its upper part separates from it, allowing the upper part to fold inward to form a reinforcement area. The lower part serves as the contact area, contacting the frame body. The contact area, after folding, has a large surface area, providing stable support. The reinforcement area, after folding inward, forms a mutually supporting structure with the other parts of the back support, enhancing the overall rigidity of the back support.

[0025] Furthermore, the reinforced area is provided with an inwardly recessed positioning part, which contacts the side area and can reinforce the side area.

[0026] The inwardly recessed positioning part on the reinforced area contacts the side area when the back support is in the supported state. It can limit and reinforce the side area, so that the reinforced area and the side area form an interactive force to maintain the support shape of the back support together, avoiding the side area from shaking or deforming when under force, and enhancing the overall stability of the back support structure.

[0027] The beneficial effects of this application are:

[0028] 1. By using paper materials and making the back support switchable, it is not only environmentally friendly and low-cost, but also improves the structural strength of the support. Furthermore, the back support can be replaced individually if it is damaged, which saves more resources.

[0029] 2. By installing back supports, the stability of the support can be improved while ensuring the contact area with the picture frame body, reducing the risk of tipping over and making the support effect better;

[0030] 3. The back support is divided into multiple areas by fold lines, which not only facilitates folding but also ensures support and structural strength. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0038] The paper composite photo frame provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0039] Example 1:

[0040] like Figures 1 to 4 As shown, this application provides a paper composite photo frame, including:

[0041] The frame itself is 100;

[0042] Back support 200, used to support the picture frame body 100;

[0043] Fold crease 300 is set on back support 200;

[0044] Both the back support 200 and the frame body 100 are made of paper, and the back support 200 can switch between an unfolded state and a supported state through the fold line 300.

[0045] In some embodiments of this application, such as Figure 1As shown, in this paper composite photo frame, both the frame body 100 and the back support 200 are made of paper, meeting the requirements for environmental friendliness and low cost. The back support 200 achieves switching between an unfolded and supported state via fold lines 300, changing the traditional fixed design where the back support 200 and frame body are integrated. This switchable design facilitates both production and transportation. During transport, it remains in the unfolded state, while the user can fold it into the supported state. This also avoids the problem of easy breakage at the folded parts caused by rigid connections in existing technologies.

[0046] Furthermore, the back support 200 can be directly connected to the frame body 100 or connected via double-sided adhesive. When the back support 200 is damaged, it can be replaced individually without discarding the entire frame, thus solving the resource waste problem of replacing the entire frame when the back support 200 breaks in existing paper frames. The frame body 100 is used to hold the photo, while the back support 200 is used to support the frame, clearly defining their respective functions.

[0047] Furthermore, the back support 200 is trapezoidal in shape when it is in the unfolded state.

[0048] When unfolded, the back support 200 is trapezoidal in shape. By utilizing the trapezoidal structure's narrower top and wider bottom, the contact area between the back support 200 and the placement surface is increased, improving stability during support. Compared to the rectangular or triangular support structures used in ordinary paper photo frames, the trapezoidal structure can more evenly distribute the weight of the photo frame body 100 and the photo, reducing the risk of tipping over due to uneven force and solving the problem of poor support performance of traditional paper materials.

[0049] Example 2:

[0050] This application provides a paper composite photo frame, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0051] like Figures 1 to 3 As shown, crease 300 includes:

[0052] Longitudinal creases 310 are distributed parallel to the vertical area of ​​the back support 200, dividing the back support 200 into a side area 320 and a support area 330 in the vertical direction.

[0053] The horizontal crease 340 is horizontally distributed in the middle of the back support 200, dividing the back support 200 into a contact area 350 and a reinforcement area 360 in the horizontal direction;

[0054] Among them, the vertical crease 310 and the horizontal crease 340 intersect perpendicularly.

[0055] In this embodiment, the fold 300 includes a longitudinal fold 310 and a transverse fold 340 that intersect perpendicularly. This intersecting design divides the back support 200 into different functional areas, making the structural layout of the back support 200 more rational. The perpendicular distribution of the longitudinal fold 310 and the transverse fold 340 guides the back support 200 to deform along a preset trajectory during folding, avoiding structural damage caused by arbitrary deformation due to unclear folding direction.

[0056] Furthermore, the reinforced area 360 is provided with an inwardly recessed positioning part 400, which contacts the side area 320 and can reinforce the side area 320.

[0057] The inwardly recessed positioning part 400 provided on the reinforcement area 360 contacts the side area 320 when the back support 200 is in the supported state. It can limit and reinforce the side area 320, so that the reinforcement area 360 and the side area 320 form an interactive force to maintain the support shape of the back support 200, avoid the side area 320 from shaking or deforming when subjected to force, and enhance the overall structural stability of the back support 200.

[0058] Example 3:

[0059] This application provides a paper composite photo frame, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0060] like Figures 1 to 4 As shown, the longitudinal crease 310 extends from the upper edge of the trapezoid to the lower edge, and the longitudinal crease 310 does not penetrate the back support 200. It folds backward along the longitudinal crease 310 to form a side area 320 for supporting the back support 200 to stand.

[0061] In this embodiment, the longitudinal crease 310 extends from the upper edge to the lower edge of the trapezoid and does not penetrate the back support 200, thus preserving the overall connectivity of the back support 200 and avoiding the defects of easy breakage caused by through creases or tear lines. The non-penetrating design ensures that some material remains connected at the crease during folding, enhancing the tear resistance of the crease area and extending the service life of the back support 200.

[0062] Meanwhile, the side area 320 formed by folding backward along the longitudinal crease 310, through the combined effect of the two side areas 320, can improve the overall standing stability of the frame and effectively avoid the problems of poor support effect and easy tipping caused by the single support surface of the traditional paper back support 200.

[0063] Example 4:

[0064] This application provides a paper composite photo frame, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0065] like Figure 2 and Figure 3 As shown, the horizontal crease 340 is located in the middle of the back support 200. Its lower part is connected to the back support 200, and its upper part is separated from the back support 200. The middle part is a horizontal crease, and the upper part can be folded inward along the horizontal crease. The lower part forms a contact area 350, and the upper part forms a reinforcement area 360 for supporting the overall structure of the back support 200.

[0066] In this embodiment, the transverse crease 340 is located in the middle of the back support 200. Its lower part is connected to the back support 200, while its upper part is separate from the back support 200, allowing the upper part to fold inward to form a reinforcing area 360. The lower part serves as a contact area 350 that contacts the frame body 100. The contact area 350 has a large folded area, providing stable support. The reinforcing area 360, after folding inward, forms a mutually supporting structure with other parts of the back support 200, enhancing the overall rigidity of the back support 200.
