[0024] like Figures 1 to 3 , Figures 5 to 9 As shown, the folding lightbox structure of this utility model includes a front connecting rod 1 and a rear connecting rod 2. The rear end of the front connecting rod 1 and the front end of the rear connecting rod 2 are nested together. A fastening hook 11 is provided on the rear end of the front connecting rod 1, and a positioning protrusion 21 for fastening the fastening hook 11 is provided on the front end of the rear connecting rod 2. A front guide slope 12 and a rear guide slope 22 are respectively provided on the opposite surfaces of the fastening hook 11 and the positioning protrusion 21. During the nesting process of the front connecting rod 1 and the rear connecting rod 2, the fastening hook 11 can be guided by the front guide slope 12 and the rear guide slope 22 to automatically slide and fasten onto the positioning protrusion 21.

[0025] This folding lightbox structure not only nests the front connecting rod 1 and the rear connecting rod 2 together, but also includes a fastening hook 11 and a positioning protrusion 21. A front guide slope 12 and a rear guide slope 22 are respectively provided on the opposite surfaces of the fastening hook 11 and the positioning protrusion 21. During the nesting process of the front connecting rod 1 and the rear connecting rod 2, the fastening hook 11 can automatically slide and fasten onto the positioning protrusion 21 guided by the front guide slope 12 and the rear guide slope 22. This allows for quick, convenient, and stable connection of the front connecting rod 1 and the rear connecting rod 2, making the connection very simple. It not only effectively improves the convenience and efficiency of unfolding, but also effectively reduces the probability of operator fatigue and ensures stable unfolding. At the same time, the guidance of the front guide slope 12 and the rear guide slope 22 reduces the probability of deformation and damage during the unfolding connection process, thus helping to extend the service life.

[0026] like Figure 2 and Figure 7As shown, the fastening hook body 11 includes a connecting strip 111, a protruding hook portion 112, and a lever portion 113. One end of the connecting strip 111 is connected to the side wall of the front connecting rod 1, and the other end of the connecting strip 111 is close to the rear end of the front connecting rod 1. A clearance gap 10 is reserved between the other end of the connecting strip 111 and the rear side wall of the front connecting rod 1. The protruding hook portion 112 is disposed on the surface of the other end of the connecting strip 111 facing the front connecting rod 1. The lever portion 113 is disposed on the other end of the connecting strip 111, and the lever portion 113 is connected to the protruding hook portion 112. The lever portion 113 is arranged in an inclined state that gradually moves away from the front connecting rod 1 from front to back. The rear wall of the lever portion 113 forms a front guide slope 12, and the front guide slope 12 extends to the protruding hook portion 112. A lever gap 20 is reserved between the front guide slope 12 and the side wall of the rear connecting rod 2. Such a fastening hook 11 not only has a very stable and reliable structure, but also achieves the fastening effect conveniently and stably, and allows users to easily unfasten it, thereby helping to further improve the reliability and applicability of the folding lightbox structure.

[0027] like Figure 8 As shown, the front end of the rear connecting rod 2 is a sleeve portion 23 with an open front end, and the positioning protrusion 21 is a raised ring portion provided on the outer circumferential surface of the sleeve portion 23. The front end face of the positioning protrusion 21 is inclined backward, forming a rear guide slope 22. The sleeve portion 23 allows the rear end of the front connecting rod 1 to be inserted, which facilitates a stable nested connection. The positioning protrusion 21 not only strengthens the structural strength of the sleeve portion 23, but also facilitates the stable fastening of the hook body 11, and helps to form a stable and reliable rear guide slope 22, thereby further improving the reliability and applicability of the folding light box structure.

[0028] like Figure 7 and Figure 8As shown, the front connecting rod 1 includes a first central shaft 13, four first strips 14, and several first reinforcing rings 15. The four first strips 14 are arranged in a circular array on the circumferential surface of the first central shaft 13, with the length direction of the first strips 14 aligned with the length direction of the first central shaft 13. Each first reinforcing ring 15 is arranged around the first central shaft 13, side by side along the length direction of the first central shaft 13, and each first reinforcing ring 15 is respectively connected to one of the four first strips 14. The rear connecting rod 2 includes a second central shaft 26, four second strips 24, and several second reinforcing rings 25. The four second strips 24 are arranged in a circular array on the circumferential surface of the second central shaft 26, with the length direction of the second strips 24 aligned with the length direction of the second central shaft 26. Each second reinforcing ring 25 is arranged around the second central shaft 26, side by side along the length direction of the second central shaft 26, and each second reinforcing ring 25 is connected to one of the four second strips 24. This not only helps control the amount of material used in the front connecting rod 1 and the rear connecting rod 2, but also ensures that the front connecting rod 1 and the rear connecting rod 2 have very stable and reliable structural strength, thereby helping to further improve the reliability and applicability of the folding light box structure.

[0029] like Figure 7 As shown, the first reinforcing ring 15 near the sleeve section 23 has been widened to make the nesting more stable and reliable.

[0030] like Figures 1 to 6 As shown, the foldable lightbox structure also includes a front block 3 and a rear block 4, which are arranged side by side. The front end of the front connecting rod 1 is non-circular and is embedded in the front block 3. The rear end of the rear connecting rod 2 is also non-circular and is embedded in the rear block 4. This ensures a stable and reliable assembly of the front connecting rod 1 with the front block 3 and the rear connecting rod 2 with the rear block 4, thereby further improving the reliability and applicability of the foldable lightbox structure.

[0031] The front connecting rod 1 is locked to the front block 3 by a screw passing through the front block 3, and the rear connecting rod 2 is locked to the rear block 4 by a screw passing through the rear block 4, which can more stably meet the requirements of nested connection.

[0032] like Figure 5 and Figure 6 As shown, the front end of the front connecting rod 1 is rectangular, and the rear end of the rear connecting rod 2 is rectangular. This not only gives the connection between the front connecting rod 1 and the front block 3, and the connection between the rear connecting rod 2 and the rear block 4, very high structural strength, but also prevents slippage when locking with screws, thus helping to further improve the stability and convenience of assembly.

[0033] like Figures 1 to 4 As shown, there are several front blocks 3 and several rear blocks 4. The front blocks 3 are arranged in a rectangular array together, and the rear blocks 4 are arranged in a rectangular array together, with each front block 3 and each rear block 4 arranged in a one-to-one correspondence. Each front block 3 is hinged to the rear block 4 behind its adjacent front block 3 by a folding rod 5, and the two folding rods 5 between adjacent front blocks 3 are hinged together at the middle. This makes the unfolding and folding of the folding lightbox structure very stable and reliable, thereby helping to further improve the stability and convenience of assembly.

[0034] like Figure 5 and Figure 6 As shown, the front block 3 has four first hinge notches 31 arranged around its longitudinal center line on its rear side, and these four first hinge notches 31 are offset from the vertical and horizontal center lines of the front block 3. The rear block 4 has four second hinge notches 41 arranged around its longitudinal center line on its front side, and these four second hinge notches 41 are offset from the vertical and horizontal center lines of the rear block 4. This not only provides a good hinge position for the folding rod 5, but also better meets the assembly requirements and ensures smooth folding and unfolding.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, front hanging fasteners 32 are provided on the front wall of the front block 3 located on the side, and rear hanging fasteners 42 are provided on the rear wall of the rear block 4 located on the side. This facilitates the hanging of the canvas, enabling convenient and stable canvas installation, and further contributing to a more stable and reliable display effect for the folding lightbox.

[0036] like Figure 1 , Figure 4 and Figure 9 As shown, fastening rods 6 are arranged between the front block 3 and the rear block 4 at the corners, and the front and rear ends of the fastening rods 6 can be detachably fastened to the front block 3 and the rear block 4, respectively. This not only facilitates stable unfolding but also makes folding convenient, thereby helping to further improve the applicability of this foldable lightbox structure.

[0037] like Figure 1 and Figure 3 As shown, support blocks 7 are respectively installed on the bottom front block 3 and rear block 4. This facilitates stable placement.
