[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Figure 1 An advertising support device 100 is shown, comprising a base 300, a display medium 400 and a display frame 200 of the present application, wherein the display medium 400 is installed in a display space 10 formed by a plurality of frames (20, 30) (see FIG. Figure 2 , Figure 5 or Figure 7 ).

[0032] Figure 2 for Figure 1 A three-dimensional diagram of the local structure of the upper corner of the display frame 200.

[0033] Reference Figures 1 to 5 The display frame 200 of the advertisement support device 100 proposed in the present application includes:

[0034] A plurality of frames (20, 30) enclosing a display space 10, the frames (20, 30) comprising a hollow outer cylinder (21, 31), the outer peripheral surface of the outer cylinder (21, 31) being concave on a side facing the display space 10 to form a receiving groove (22, 32), the receiving groove (22, 32) extending along the edge of the display space 10; and

[0035] A plurality of connecting members 40 connecting two adjacent frames (20, 30); characterized in that:

[0036] At least one frame 20 among the multiple frames (20, 30) also includes an inner tube 26 embedded in the inner cavity of the outer tube 21, the inner tube 26 extends between the two ends of the corresponding outer tube 21, the inner wall surface of the outer tube 21 includes two opposite first limiting surfaces 23, the first limiting surfaces 23 extend along the axial direction of the corresponding outer tube 21, and the outer peripheral surface of the inner tube 26 is limitedly matched with the first limiting surface 23.

[0037] In this embodiment, the number of frames (20, 30) is usually 4, but it can be adjusted as needed, for example, two frames are connected to the base 300 to enclose a triangular display space; or three frames are connected to the base 300 to enclose a rectangular display space. In a preferred combination, the outer cylinder (21, 31) can be made of lightweight and corrosion-resistant aluminum or aluminum alloy, and the inner cylinder 26 can be made of iron with lower material and manufacturing costs, but it is not limited to this. The connecting member 40 is usually L-shaped as an example, but in order to facilitate the connection of adjacent frames (20, 30), the connecting member 40 can be set to other shapes, such as a straight strip. The two first limiting surfaces 23 are relatively arranged in the depth direction of the accommodating groove 22, and can also be relatively arranged in a direction perpendicular to or intersecting the depth direction of the accommodating groove 22. In addition, the first limiting surface 23 can be a plane as shown in the figure, or it can be a curved surface.

[0038] The display frame 200 of the advertising support device 100 of the present invention is provided with an inner cylinder 26 in the inner cavity of the outer cylinder 21 of the frame 20. The inner cylinder 26 extends between the two ends of the outer cylinder 21 and cooperates with the first limiting surfaces 23 opposite to the inner wall of the outer cylinder 21 to form a reinforcing support for the outer cylinder 21 from the inside of the outer cylinder 21. Therefore, even if the structural strength of the outer cylinder 21 itself is relatively low, the accommodating groove 22 is not easy to deform. In this way, the inner cylinder 26 can adopt a material or manufacturing process with lower cost than the outer cylinder 21, thereby achieving the beneficial effect of flatly supporting the display medium 400 or smoothly guiding the sliding components at a relatively low cost.

[0039] Further, please refer to Figure 6 and Figure 7 The two first limiting surfaces 23 are arranged opposite to each other in the depth direction of the receiving groove 22, and one of the first limiting surfaces 23 and the bottom wall surface of the receiving groove 22 are arranged opposite to each other at the same position of the outer tube 21. In this way, the structural strength of the receiving groove 22 can be particularly increased, thereby preventing the deformation of the receiving groove 22 while preventing the overall deformation of the frame 20.

[0040] Furthermore, the outer circumferential surface of the outer tube 21 is concave on the side away from the display space 10 to form a structural reinforcement groove 24, and the structural reinforcement groove 24 extends along the axial direction of the corresponding outer tube 21. The structural reinforcement groove 24 is added to the outer circumferential surface of the outer tube 21 to further improve the structural strength of the outer tube 21. The other first limiting surface 23 of the two first limiting surfaces 23 and the bottom surface of the structural reinforcement groove 24 are arranged in opposite directions at the same position of the outer tube 21, so that the improvement effect of the structural reinforcement groove 24 on the structural strength of the outer tube 21 can be further enhanced.

[0041] Further, refer to Figures 1 to 5 , Figure 6 , Figure 8 and Fig. 9The two first limiting surfaces 23 are arranged opposite to each other in the first direction, and the inner wall surface of the outer cylinder 21 also includes two second limiting surfaces 25 opposite to each other in the second direction. The second direction intersects with the first direction, and the second limiting surfaces 25 extend along the axial direction of the corresponding outer cylinder 21. The outer peripheral surface of the outer cylinder 21 is limited and matched with the second limiting surfaces 25.

[0042] In this embodiment, two pairs of limiting surfaces are provided to cooperate with the inner tube 26 , so that the outer tube 21 can be supported in multiple directions, thereby making the support of the frame 20 more reliable.

[0043] Furthermore, both ends of the inner tube 26 are open, and at least one of the multiple frames 20 further includes a blocking member 27 , which covers the opening at the end of the inner tube 26 , and the blocking member 27 is fixedly connected to the inner tube 26 and the connecting member 40 .

[0044] In this embodiment, the plugging member 27 is provided to facilitate the connection between the inner cylinder 26 and the connecting member 40, and the outer cylinder 21 sleeved on the outer periphery of the inner cylinder 26 is indirectly connected, so that the outer cylinder 21 does not need to be directly fixedly connected to the connecting member 40, thereby simplifying the structure of the outer cylinder 21, for example, making the outer cylinder 21 more suitable for extrusion or injection molding processes.

[0045] Further, refer to Figure 3 as well as Figures 6 to 9 In order to facilitate the installation of the display medium 400 and ensure the connection strength of the two adjacent frames 20, the blocking piece 27 is welded and fixed to the inner tube 26 and has a fixing hole 28, the end of the inner tube 26 is retracted relative to the end of the outer tube 21, the end of the connecting piece 40 is embedded in the inner cavity of the end of the outer tube 21 and has a through hole 41 corresponding to the fixing hole 28; the display frame 200 also includes a fastener 50, which passes through the through hole 41 and is detachably fixed to the connecting piece 40. In this way, the two adjacent frames 20 can be quickly installed and removed.

[0046] Further, refer to Figures 2 to 4 ,as well as Figures 6 to 9 A countersunk hole 42 is formed on one side of the through hole 41 away from the blocking member 27 , and the outer end of the fastener 50 is located in the countersunk hole 42 ; the display frame 200 further includes a cover body 60 for covering the countersunk hole 42 .

[0047] In this embodiment, the countersunk hole 42 can better accommodate the outer end of the fastener 50, and the cover 60 can protect the fastener 50 by covering the countersunk hole 42, and can also make the appearance of the display frame 200 neater.

[0048] Furthermore, in order to facilitate opening or covering the countersunk hole 42 , a mounting groove 43 is provided on the outer side of the connecting member 40 corresponding to the countersunk hole 42 , and the cover body 60 can be slidably installed in the mounting groove 43 to cover or open the countersunk hole 42 .

[0049] Furthermore, in order to prevent the cover body 60 from falling off during the sliding process, two opposite sidewalls of the installation groove 43 are provided with sliding grooves 44, and the edge of the cover body 60 is provided with sliding protrusions 61 corresponding to the sliding grooves 44, and the sliding protrusions 61 can slide with the sliding grooves 44. In this way, through the limited cooperation between the sliding protrusions 61 and the sliding grooves 44 in the depth direction of the installation groove 43, the cover body 60 can be better slid on the preset path without falling off. Preferably, one side of the sliding groove 44 is opened for easy installation.

[0050] Further, please refer again to Figure 1 , Figure 3 and Figure 5 The multiple frames (20, 30) include two horizontally arranged frames 30 and two vertically arranged frames 20, the length of the vertically arranged frames 20 is greater than the length of the horizontally arranged frames 30, and only the inner cylinder 26 is arranged in the inner cavity of the outer cylinder 21 of the vertically arranged frames 20.

[0051] In this embodiment, the longer the frame (20, 30) is, the easier it is to bend. The inner cylinder 26 is only arranged in the inner cavity of the outer cylinder 21 of the vertically arranged frame 20, which can improve the structural strength of the display frame 200 and reduce the cost of the display frame 200.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
