However, if the hooks are not installed by professionals or those with insufficient experience, unevenness may occur, affecting the installation effect of the frame. Furthermore, decorative paintings installed using traditional hooks cannot be flipped or are inconvenient to flip.

[0003] Existing flip-type decorative paintings typically consist of a base frame, a decorative frame, and hinges. During installation, since the hinges cannot be disassembled, they are usually installed first to allow the base frame and decorative frame to flip and connect. Then, the decorative frame is flipped to the open position, and the base frame is installed to the wall using nails or screws. During the installation process, although the decorative frame is in the open position, it still affects the installation operation to some extent. Currently, flip-type decorative paintings using existing hinges are not only cumbersome to install, but also require the base frame to serve as a support for the flipping of the decorative frame, making the structure relatively complex.

Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1:

[0033] This utility model provides a hinge component 1 for fixing decorative paintings, see reference. Figures 1 to 8 As shown, the hinge assembly 1 for fixing the decorative painting includes a first leaf 11 and a second leaf 12.

[0034] The first page 11 and the second page 12 are detachably connected to the support frame 3 of the decorative painting and the wall, respectively. The first page 11 is provided with a snap-fit ​​part, and the second page 12 is provided with a locking part corresponding to the snap-fit ​​part.

[0035] During installation, the user installs the first page 11 onto the support frame 3 of the decorative painting, and the second page 12 onto the wall. Then, the user holds the support frame 3 and aligns the snap-fit ​​part of the first page 11 with the snap-fit ​​part of the second page 12, and snaps the snap-fit ​​part with the snap-fit ​​part.

[0036] In normal use, the first page 11 and the second page 12 are in a flipped-open state, at which time the decorative painting is attached to the wall.

[0037] When opened, the decorative painting is flipped forward, and the first page 11 rotates synchronously, with the latching part rotating relative to the engaging part.

[0038] To close, simply flip the decorative painting in reverse so that it adheres to the wall.

[0039] The snap-fit ​​part and the engaging part of this utility model combine a snap-fit ​​structure and a rotating structure. While ensuring that the first page 11 and the second page 12 are easy to assemble and disassemble, they do not affect the rotation between them. On the one hand, it ensures the effect of the decorative painting flipping relative to the wall, making the installation of the decorative painting more convenient and faster. On the other hand, the decorative painting does not need a bottom frame, making the structure simpler.

[0040] Example 2:

[0041] Example 2 is based on Example 1:

[0042] refer to Figures 1 to 8 As shown, the snap-fit ​​part is configured as a snap-fit ​​shaft 113, and the engaging part is configured as an engaging groove 122. The engaging groove 122 is dimensionally matched with the snap-fit ​​shaft 113. The snap-fit ​​shaft 113 is disposed in the engaging groove 122 and can rotate relative to the engaging groove 122.

[0043] The locking shaft 113 and the locking groove 122 cooperate with each other to ensure the flipping effect of the first sheet 11 and the second sheet 12.

[0044] As an optional implementation, at least one section of the opening edge of the engaging groove 122 extends in an arc direction to form an engaging edge 123, through which the engaging shaft 113 can be securely engaged in the engaging groove 122.

[0045] The snap-fit ​​edge 123 can effectively ensure the connection stability between the snap-fit ​​shaft 113 and the snap-fit ​​groove 122, and prevent the snap-fit ​​shaft 113 from disengaging from the snap-fit ​​groove 122 during rotation.

[0046] Furthermore, the middle sections of the two opening sides of the engaging groove 122 extend in an arc direction, thus forming two opposing engaging edges 123. The distance between the two engaging edges 123 is slightly smaller than the diameter of the engaging shaft 113. During installation, the engaging shaft 113 is aligned with the gap between the two engaging edges 123, and then pressing pressure is applied. The engaging shaft 113 can then be squeezed and engaged into the engaging groove 122 through the gap.

[0047] Two snap-fit ​​edges 123 are used to further improve the snap-fit ​​strength between the snap-fit ​​shaft 113 and the snap-fit ​​groove 122.

[0048] As an optional implementation, a first mounting part is provided on the first page 11, which is used to connect the support frame 3 of the decorative painting.

[0049] The first mounting part includes at least one first mounting hole 114. During installation, a screw passes through the first mounting hole 114 to mount the first leaf 11 onto the support frame 3 of the decorative painting.

[0050] Specifically, the number of the first mounting holes 114 is set to two.

[0051] As an optional implementation, the first sheet 11 includes a first sheet body 111, and a first mounting hole 114 is disposed through the first sheet body 111.

[0052] The two opposite sides of the first sheet body 111 are respectively designated as the first side and the second side. The first side of the first sheet body 111 is provided with two fixing seats 112. The two fixing seats 112 are symmetrically arranged. The snap-fit ​​shaft 113 is arranged between the two fixing seats 112. The first sheet body 111, the fixing seats 112 and the snap-fit ​​shaft 113 are integrally formed.

[0053] As an optional implementation, the second side of the first sheet body 111 is provided with a clearance slope angle 115.

[0054] During the process of flipping and opening the decorative painting, the 115-degree bend allows the wall to be adjusted, thus ensuring the painting can be opened to its full extent.

[0055] As an optional implementation, a second mounting part is provided on the second page 12, which is used to connect to the wall.

[0056] The second mounting part includes a second mounting hole 124, which is adapted to an expansion bolt.

[0057] The second mounting part includes a third mounting hole 125, which is adapted to a nail.

[0058] Specifically, the second mounting hole 124 is located in the middle of the second page body 121, and the number of the third mounting holes 125 is set to two, symmetrically distributed on both sides of the second mounting hole 124.

[0059] During the actual installation process, users can choose to use expansion bolts or nails for installation according to their actual needs. The nail installation method does not require drilling holes in the wall.

[0060] The second installation section allows for more diverse installation methods for decorative paintings, catering to the different needs of different users.

[0061] As an optional implementation, the second sheet 12 includes a second sheet body 121, on which a reinforcing boss 126 is provided. The reinforcing boss 126 is integrally formed with the second sheet body 121. The second mounting hole 124 and the third mounting hole 125 are both provided on the reinforcing boss 126 and penetrate through the reinforcing boss 126 and the second sheet body 121.

[0062] The reinforced boss 126 effectively improves the structural strength of the second page 12. Furthermore, the back of the supporting frame 3 of the decorative painting has a hollow structure. When the painting is closed, the reinforced boss 126 can be inserted into and abut against the hollow structure, ensuring a proper fit between the painting and the wall. Additionally, when using nails for installation, the reinforced boss 126 provides a deeper third mounting hole 125. During installation, the deeper third mounting hole 125 supports the nails, eliminating the need for manual support and further facilitating the installation process.

[0063] The engaging groove 122 is integrally provided at the edge of the second sheet body 121.

[0064] Alternatively, in practical applications, if the back of the support frame 3 is a non-perforated structure, the reinforcing boss 126 is not provided on the second page body 121.
