Description

Technical Field

[0001] The utility model relates to the technical field of advertising light boxes, and particularly relates to a side-opening borderless fabric light box. Background Art

[0002] A fabric light box is an advertising display device. Its name comes from the installation method of the light box fabric, that is, by buckling the four sides of the advertising picture and then tightening and fixing it with cable ties, thus forming a unique fabric structure. The fabric light box is suitable for installation environments with strong winds, but its advertising display effect is not very ideal. Therefore, it is very necessary to develop a fabric light box with good advertising display effect and can adapt to strong wind environments. The patent document with the publication number CN219435504U discloses a side-opening borderless fabric light box, which adopts a main light box profile and a flip cover that are rotatably connected. A clamping edge is arranged at the front end of the flip cover and is clamped tightly with the canvas support edge of the main light box profile. The canvas is installed on the canvas fixing hanging piece through the clamping part of the two. The canvas is stable and firm and not easy to loosen. Compared with the existing light box with a border, it can adapt to the installation environment with stronger wind, and the advertising display effect is better; by opening the flip cover and exposing the canvas fixing hanging piece, the installation or replacement of the canvas can be carried out, and the operation is more simple and fast.

[0003] The above technical solution still has the following deficiencies: The device uses a flip cover and a spring piece to press and fix, but the supporting strength of the spring piece is difficult to guarantee, and the area of the flip cover is large. Once encountering a strong wind environment, the flip cover is likely to break free from the restraint of the spring piece and turn outwards passively, or even fall off, thus losing the shielding of the canvas edge and the borderless effect; moreover, when installing this device, the canvas needs to be initially positioned through the fixing hanging piece, the process is redundant, and additional spring pieces need to be installed, which brings inconvenience to the installation operation.

In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model in conjunction with the accompanying drawings.

[0022] Figures 1-4 Shown is a schematic diagram of the entire structure of a side-opening borderless fabric light box of the present utility model. Please refer to Figures 1-4 A side-opening borderless fabric light box according to this embodiment includes a main frame 100 of the light box profile. The front of the main frame 100 of the light box profile has an opening and is used for laying out a canvas 300. Inner clamping plates 120 are provided around the inner side of the main frame 100 of the light box profile. There is a gap between the inner clamping plates 120 and the inner peripheral edges of the main frame 100 of the light box profile. This gap is a positioning slot 130. One end of the positioning slot 130 and near the position of the canvas 300 is open to the outside. A retaining pin 200 is inserted and fitted inside the positioning slot 130 in a matching manner. The outer end of the retaining pin 200 is fixedly connected to a surrounding edge plate 210. Among them, the edge extension of the canvas 300 is clamped inside the positioning slot 130 through the retaining pin 200. The contact surfaces of the retaining pin 200 and the positioning slot 130 are in an unevenly-fitted match. The surrounding edge plate 210 abuts and covers the opening edge of the main frame 100 of the light box profile and the edge of the canvas 300.

[0023] There is also a fixedly integrated connecting portion 122 between the inner end of the inner clamping plate 120 and the main frame 100 of the light box profile. There is also a recessed portion 123 at the junction of the connecting portion 122 and the inner clamping plate 120. It can be understood that the recessed portion 123 can form a deformation avoidance for the inner clamping plate 120 during the insertion process, so that the retaining pin 200 can be smoothly inserted into the positioning slot 130. On the side of the inner clamping plate 120 facing the positioning slot 130 and along the depth direction of the positioning slot 130, there is at least one second slot 121. On the inner side of the peripheral edges of the main frame 100 of the light box profile and facing the positioning slot 130, there is a first slot 110 corresponding to the second slot 121. Both sides of the retaining pin 200 have convex portions 220 that match the first slot 110 and the second slot 121. The outer edge of the inner clamping plate 120 is flush with the outer edge of the main frame 100 of the light box profile near the opening. The outer edge of the outer end of the surrounding edge plate 210 is flush with the outside of the main frame 100 of the light box profile. In this way, the surrounding edge plate 210 can form a covering and protection for the outer edge of the light box, achieving a borderless effect. Specifically, during installation, the redundant part of the edge of the canvas 300 is stuffed into the positioning slot 130 by using the retaining pin 200. With the cooperation of the slots and the convex portions, the four sides of the canvas 300 are firmly clamped and fixed inside the peripheral edges of the main frame 100 of the light box profile. And after the retaining pin 200 is completely inserted, the surrounding edge plate 210 can form a covering and protection for the edges of the canvas 300 and the main frame, thus forming a borderless effect with better visual appearance. In summary, compared with the existing side-opening borderless fabric light box, its connection stability is better, it can effectively resist the looseness or expansion caused by strong winds, the structure is also simpler, and the installation operation is more convenient.

[0024] Furthermore, on the inner side of the main frame 100 of the light box profile, there is also a light source lamp panel 400 opposite to the canvas 300. It can be understood that the light-emitting surface of the source lamp panel 400 has a number of uniformly distributed LED light beads. After being powered on, it can form a wider and more uniform light mapping on the canvas 300.

[0025] Furthermore, on the back of the main frame 100 of the light box profile, there is a mounting bracket 500 that abuts against the carrier. A bolt 600 is connected between the mounting bracket 500 and the main frame 100 of the light box profile. Here, the mounting bracket 500 can be a galvanized square pipe, angle steel, etc., usually made of metal material, and can firmly fix the light box in cooperation with the bolt 600.

[0026] In summary, for a side-opening borderless pull-up light box according to this embodiment, during installation, the excess part of the edge of the canvas 300 is inserted into the positioning slot 130 by using the snap pin 200. Under the cooperation of the slot and the convex part, the four sides of the canvas 300 are firmly clamped and fixed on the inner sides of the four sides of the main frame 100 of the light box profile. And after the snap pin 200 is completely inserted, the border plate 210 can cover and protect the canvas 300 and the edge of the main frame, thus forming a borderless effect with better visual appearance. In summary, compared with the existing side-opening borderless pull-up light box, its connection stability is better, it can effectively resist the looseness or expansion caused by strong wind, and the installation operation is convenient.

[0027] Although the present invention has been described above with reference to the embodiments, however, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention.
