At present, various advertising boards exist in streets and alleys of cities, the most familiar advertising board is the advertising board arranged at a bus stop board, and the advertising boards can display advertisements in the daytime and at night. In daytime, people can see the advertisement content on the billboard clearly under the condition of natural light, and at night, the content on the billboard is illuminated by the internal backlight of the billboard, so that people can see the advertisement content clearly.

The advertising board mainly comprises an advertising box body, and the advertising box body mainly comprises a backlight part, a frame body and an advertising board. The backlight part provides illumination, and the frame body provides a supporting function for supporting the advertising board on which advertising contents such as advertising posters are pasted. The frame body in the existing advertisement box body comprises four fixing frames which are vertically, horizontally and vertically arranged, and the four fixing frames are fixedly connected end to end through corner pieces. When the advertisement box body is assembled, the backlight part and the advertisement board are firstly installed inside the frame body, and then the four fixing frames of the frame body are fixed through the four corner pieces. The advertising box body with such a structure is troublesome to assemble. In addition, if the backlight portion or the advertisement board needs to be replaced, the frame needs to be disassembled, so that it is inconvenient to replace the components. In order to solve the technical problem that the advertisement box body is inconvenient to disassemble and assemble, the utility model CN201922286339.3 applied before the inventor proposes the assembly of the advertisement box body through a splicing mode, so that the disassembly and the assembly of the advertisement box body become easy. However, the utility model provides a grafting mode is still not simple and convenient enough, and it has still used braced frame body, and advertisement box structure is also not simple enough, for this reason, this application provides an advertisement case, and this advertisement case's structure is simpler, and the dismouting is more convenient.

Disclosure of Invention

The utility model provides a simple to disassemble and assemble's bill-board carries out the joint through supporting frame and bottom plate kink to constitute the advertisement box. This advertisement box simple structure, easy dismounting to improve dismouting efficiency, labour saving and time saving.

The experiment adopts the following technical scheme:

an advertisement box comprises a bottom plate (1), an LED lamp bar (2), a light guide plate (3), a supporting frame (4) and an advertisement plate (5); the LED light bar (2) is fixed in the middle of the bottom plate (1), and the light guide plate (3) is positioned right above the LED light bar; the LED lamp strip (2) is provided with a plurality of LED lamp beads, and light emitted by the LED lamp beads irradiates the advertising board (5) through the light guide plate, so that illumination light is provided for the advertising board (5); the method is characterized in that: two sides of the bottom plate (1) comprise bent parts (11), and first clamping grooves (12) are formed in the bent parts (11); a convex block (41) is arranged on the outer side surface of the supporting frame (4), a slot (42) and a step portion are arranged on the inner side surface of the supporting frame (4), and the step portion comprises a step surface (43); the bending part (11) is positioned on the outer side of the supporting frame (4); the convex block (41) is clamped and fixed with the first clamping groove (12), and two ends of the light guide plate (3) are fixed in the inserting grooves (42); the advertising board (5) is fixed on the step surface through an adhesive; a plurality of first clamping grooves (12) are formed in the bent portion (11), and the plurality of first clamping grooves (12) are evenly distributed in the length direction of the bent portion (11).

Preferably, a plurality of LED lamp beads on each LED lamp strip are connected in series, and the plurality of LED lamp strips are connected in parallel; the LED lamp beads are driven to emit light through the LED driving circuit.

The utility model discloses a mode of joint will support frame and bottom plate and carry out fixed connection to form the advertisement case, and wherein need not to use extra framework of support to support the advertising panel, thereby simplified the structure of advertisement box, and the dismouting is more convenient.

Detailed Description

As shown in fig. 1, it is a sectional view of the box body of the present invention; the LED light guide plate comprises a bottom plate 1, an LED light bar 2, a light guide plate 3, a supporting frame 4 and an advertising plate 5. The left side and the right side of the bottom plate 1 are provided with bending parts 11, and are fixedly connected with the supporting frame 4 through the bending parts 11; the bending portion 11 is provided with a first engaging groove 12, as shown in fig. 3. As shown in fig. 2, a plurality of LED light bars 2 are disposed in the middle of the bottom plate, the LED light bars 2 include a plurality of LED light beads 21, and the LED light bars 2 provide an illumination light source for providing illumination light for the advertisement board. The bottom plate is a metal bottom plate, so that heat generated by the LED lamp beads can be easily dissipated. The LED light bar is fixed on the bottom plate in a magnetic manner, the magnetic fixing manner is only an example and is not limited, and the LED light bar can be fixed on the bottom plate in other fixing manners. Set up a plurality of LED lamp pearls 21 on LED lamp strip 2, thereby LED lamp strip 2 arranges magnet through the back and adsorbs on metal substrate, because LED lamp pearl produces the heat when luminous, consequently can dispel the heat through metal substrate. Meanwhile, the LED lamp beads on each LED lamp strip are connected in series, the LED lamp beads are connected with the driving device through leads at the end parts of the LED lamp strips, the LED lamp strips 2 are connected in parallel, and the driving device drives the LED lamp beads to emit light, so that the backlight effect is achieved. The light guide plate 3 is positioned right above the LED lamp strip, and light emitted by the LED lamp irradiates the advertising board 5 after passing through the light guide plate 3. The light guide plate 3 can uniformly mix and emit the light emitted from the LED lamp, so that the light irradiating the advertisement board 5 is uniform incident light.

As shown in fig. 1, the supporting frame 4 includes left and right supporting frames, which have the same structure, and the supporting frame on the right side is taken as an example for detailed description. The outer side of the right support frame comprises a projection 41, said projection 41 projecting towards the outer side. The bending part 11 of the bottom plate is located on the outer side of the supporting frame, the protruding block 41 corresponds to the first clamping groove 12 on the bending part 11 in a one-to-one mode, and the protruding block 41 is clamped into the first clamping groove 12, so that the supporting frame and the bending part of the bottom plate are fixed together. The right support frame has an insertion groove 42 on the inner side thereof, into which the end of the light guide plate 3 is inserted, thereby fixing the light guide plate directly above the bottom plate. The inner side surface of the right supporting frame is provided with a step surface 43, and the advertisement board 5 is fixed on the step surface through glue.

As shown in fig. 3, the bent portion 11 of the bottom plate 1 has a plurality of first locking grooves 12, and the plurality of first locking grooves 12 are uniformly distributed in the length direction of the bent portion; a plurality of bumps 41 are also arranged on the outer side of the supporting frame 4, and the number of the bumps corresponds to that of the first clamping grooves 12, so that the supporting frame and the bottom plate are more firmly connected.

The utility model discloses an advertisement box is through installing bottom plate, support frame in supporting the frame through the joint mode to simplify the structure of advertisement box, saved the braced frame body, the structure is simpler and the dismouting is more convenient.
