[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] according to Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this embodiment proposes an integrated frame that facilitates the replacement of the painting core, including an outer frame 1 and an inner frame 2. The outer frame 1 has an outer display window 11 on its front side, and the outer display window 11 is connected to a frame slot 12 on the side of the outer frame 1.
[0027] The inner frame 2 is slidably disposed inside the frame slot 12. The front of the inner frame 2 has a painting core slot 23, which is connected to the inner display window 22 on the side of the inner frame 2. The inner display window 22 and the frame slot 12 are on the same side.
[0028] The bottom of the outer frame 1 is provided with a first positioning member for fastening the inner frame 2, the bottom of the inner frame 2 is provided with a second positioning member for fastening the painting core, and the bottom of the outer frame 1 is provided with a sliding groove 13 to facilitate the sliding of the second positioning member.
[0029] The picture frame in this solution offers two options for mounting the picture panels, allowing you to choose the appropriate method depending on whether blank space is desired.
[0030] When there is no blank space, the painting core to be displayed is laid flat on the upper part of the inner frame 2. After the inner frame 2 is pushed into the outer frame 1, the painting core is located between the frame slot 12 and the upper surface of the inner frame 2. The inner frame 2 is secured by the first positioning piece at the bottom of the outer frame 1 to ensure that the painting core does not shake.
[0031] When blank space is needed, insert the painting core to be displayed into the inner frame 2 through the painting core slot 23 on the side of the inner frame 2, and then secure the painting core through the second positioning piece at the bottom of the inner frame 2 to ensure that the painting core does not shake.
[0032] The strips on the sides of the inner display window 2 create a blank space within the outer display window 11, preventing a feeling of oppression caused by over-filling of the painting elements and improving visual balance. The frame adopts a plug-in design; when changing the painting element, simply pull out the inner frame 2 inside the outer frame 1, making it convenient for users to quickly replace the painting element.
[0033] Regarding the first positioning component:
[0034] The first positioning component includes multiple threaded holes A at the bottom of the outer frame 1. A first positioning bolt 14 is fitted onto the threaded holes A, and the first positioning bolt 14 passes through the threaded holes A and extends into the frame slot 12. After the inner frame 2 is pushed into the outer frame 1, the first positioning bolt 14 at the bottom of the outer frame 1 is rotated. The first positioning bolt 14 will screw into the outer frame 1 and support the inner frame 2 from the bottom. The inner frame 2 compresses the painting core placed between the top of the inner frame 2 and the inner sidewall of the outer frame 1, ensuring that the painting core will not wobble inside the outer frame 1 when displayed.
[0035] Regarding the second positioning component:
[0036] The second positioning component includes multiple threaded holes B at the bottom of the inner frame 2. A second positioning bolt 21 is fitted onto each threaded hole B, passing through the threaded hole B and extending into the inner display window 22. After the painting is fully inserted into the inner display window 22, the second positioning bolt 21 at the bottom of the inner frame 2 is rotated. The second positioning bolt 21 screws into the outer frame 1, contacting and applying pressure to the bottom of the painting, ensuring that the painting remains stable within the inner frame 2 during display.
[0037] To facilitate the user in pulling the inner frame 2, which is pushed into the outer frame 1, a lever 32 is provided at one end of the inner frame 2. The lever 32 is on the same side as the picture core slot 23 and is rotatably connected to the inner frame 2. The outer frame 1 is provided with a magnetic attraction structure 3 that cooperates with the lever 32. When the inner frame 2, which is pushed into the frame slot 12, is pulled outward, the lever 32 can be engaged to directly pull the outer frame 1.
[0038] Specifically, the magnetic structure 3 includes a first magnetic clasp 31 and a second magnetic clasp 33. The first magnetic clasp 31 is fixedly disposed on the outside of the outer frame 1, and the second magnetic clasp 33 is fixedly disposed on the end of the lever 32 away from the inner frame 2. The second magnetic clasp 33 is attracted to the first magnetic clasp 31. After the inner frame 2 is pushed into the frame slot 12, the lever 32 is rotated. After the lever 32 is engaged with the side of the outer frame 1, the second magnetic clasp 33 at the upper end of the lever 32 will be attracted to the first magnetic clasp 31 on the outside of the outer frame 1. The lever 32 will block the frame slot 12 and the picture core slot 23 from the side of the outer frame 1, ensuring that the picture core will not fall out from the inner display window 22 and the gap between the inner frame 2 and the outer frame 1.
[0039] It is worth explaining in detail that the slide groove 13 is connected to the frame slot 12, and the second positioning bolt 21 is slidably disposed inside the slide groove 13. After the inner frame 2 is pushed into the frame slot 12, the second positioning bolt 21 of the inner frame 2 will also slide into the slide groove 13. The setting of the slide groove 13 can ensure that the second positioning bolt 21 will not collide with the outer frame 1 when the inner frame 2 is inserted or removed, and at the same time, it is convenient for the user to rotate the second positioning bolt 21 from the outside of the outer frame 1.
[0040] In a preferred embodiment, the back of the outer frame 1 is provided with at least two sets of hook plates for hanging the outer frame 1, and the hook plates are fixedly connected to the outer frame 1. The picture frame can be hung on a bracket or fastener on the wall via the hook plates.
[0041] How this application works:
[0042] When there is no blank space, lay the painting core to be displayed flat on the upper part of the inner frame 2. After pushing the inner frame 2 into the outer frame 1, the painting core is located between the frame slot 12 and the upper surface of the inner frame 2. The inner frame 2 is secured by the first positioning piece at the bottom of the outer frame 1, which ensures that the painting core will not shake.
[0043] When blank space is needed, insert the painting core to be displayed into the inner frame 2 through the painting core slot 23 on the side of the inner frame 2, and then secure the painting core through the second positioning piece at the bottom of the inner frame 2 to ensure that the painting core will not shake.
[0044] The strips on the sides of the inner display window 2 create a blank space within the outer display window 11, preventing a feeling of oppression caused by over-filling of the painting elements and improving visual balance. The frame adopts a plug-in design; when changing the painting element, simply pull out the inner frame 2 inside the outer frame 1, making it convenient for users to quickly replace the painting element.
