Description

TECHNICAL FIELD

[0001] The utility model belongs to the exhibition display field, concretely relates to a backlight exhibition display lamp box. BACKGROUND

[0002] The lamp box is widely used in the fields of advertisement and product exhibition display due to its structural advantages and extraordinary display effect.

[0003] At present, the lamp box structure mainly has two kinds: one is the lamp box of side -in type backlight source structure, for example, the side light source lamp box of patent application number 201920277932.9 discloses, it is mainly composed of light guide plate and light source, installs the light source in the light guide plate side, is equipped with the light guide point of engraving or printing at the bottom of light guide plate. Due to the light guide distance limit, the lamp box of side -in type backlight source structure is suitable for the product of smaller luminous area. At the same time, due to the light source of the two sides or four around of light guide plate, the dark area caused by the light source body exists in the two sides or four around of light guide plate, and the shadowless splicing cannot be realized. The other is the lamp box of direct -down type backlight source structure, for example, the lamp box backlight source assembly of patent application number 201210182535.6 discloses, it is mainly composed of panel, light source and box, the panel is installed in the front side of box, and the back side is fixed with backboard, and the light source is directly installed in the back side of box, it has the advantages such as high brightness, strong controllability of light source, and therefore its application is extremely wide, such as advertising lamp box, signboard lamp box, guide sign lamp box and window lamp box etc. However, due to the thick wall of the box around the box, there will be serious dark shadow between the boxes after splicing, so shadowless splicing cannot be realized. Moreover, due to the existence of backboard, side plate and other things, transportation is inconvenient.

[0004] Of course, at present, there is also a lamp box hanging curtain type, which punches holes on the upper and lower profile frames, and installs the lamp curtain through the hook. Since the lamp curtain is not fixed around and in the middle part, it is easy to stick to the picture to form a light spot, which affects the effect. Moreover, when expansion and extension are needed, dark areas will appear after splicing, and shadowless splicing cannot be realized. SUMMARY

[0007] As a further improvement of the utility model, the effect of modular splicing is realized: the frame further comprises vertical support rods; the upper and lower horizontal rods each comprise two or more unit horizontal rods, and are provided with intermediate connecting pieces; the adjacent horizontal rods are connected through the intermediate connecting pieces; a corresponding number of vertical support rods are provided corresponding to the intermediate connecting pieces; the back of each vertical support rod is provided with two vertical clamping grooves; the two ends of each vertical support rod are connected to the corresponding intermediate connecting pieces above and below; the frame is divided into a plurality of light box units through the vertical support rods; and each light box unit is provided with a backlight curtain.

[0008] In order to realize higher and larger exhibition effects, the further improvement of the utility model is that the left and right side rods each comprise two or more unit side rods, and are provided with intermediate connecting pieces; the unit side rods are connected through the intermediate connecting pieces; each vertical support rod comprises two or more unit vertical support rods, and is provided with a support rod connecting piece; the adjacent unit vertical support rods are connected through the support rod connecting piece; the length and number of the unit vertical support rods correspond to the length and number of the unit side rods.

[0009] As a further improvement of the utility model: in order to ensure that the backlight curtain is not close to the light box canvas and to strengthen the structural stability of the frame, each light box unit is provided with at least one unit horizontal support rod; the two ends of the unit horizontal support rod are connected to the intermediate connecting pieces and the support rod connecting piece respectively.

[0010] In order to realize the flatness and uniformity of the fixed backlight curtain, the horizontal rod and the side rod are connected through a corner connecting piece; the back of the corner connecting piece is provided with a corner clamping groove; and the corner clamping groove is connected to the clamping grooves on the horizontal rod and the side rod respectively.

[0011] In order to further facilitate installation and production, the unit horizontal rod and the unit side rod have the same structure; the intermediate connecting piece has the same structure; and the back of the intermediate connecting piece is provided with a cross clamping groove for clamping the clamping strip of the backlight curtain.

[0012] In order to further facilitate the installation of the canvas, the unit horizontal rod of the lower horizontal rod is provided with a canvas clamping groove on the front face. The original sleeving through the zipper fixing mode is changed to a clamping mode, so that the structure is further simplified.

[0013] The structural advantage of the utility model is that:

[0014] 1. The backlight curtain four clamping fixing mode is adopted instead of the traditional hanging structure, the light source is more stable, the exhibition effect is better, and the phenomenon of shaking or close to the canvas does not occur.

[0015] 2. This utility model achieves the construction of exhibition screens of different sizes by varying the number of unit crossbars and unit sidebars, breaking through the original concept of fixed lightbox size and forming a modular assembly structure.

[0016] 3. This utility model can divide the overall frame into several light box units by using vertical support rods, and continuously display different images on the whole display stand. Furthermore, through the setting of slots and other features, shadowless splicing between light box units can be achieved.

[0017] 4. Through design, this utility model unifies the size and structure of more parts, thereby greatly reducing production costs and making the packaging smaller, which makes subsequent transportation and installation more convenient and faster. Attached Figure Description
