Placing advertisement paper on the rear side of the transparent panel 3, clamping the clamping plate 4 at the bottom of the housing 1 with the bottom shell 2, and sleeving the housing 1 on the outer side of the bottom shell 2; and the pins 11 are inserted into the first pin holes 9 and the second pin holes 10, so that the housing 1 is further fixed with the bottom shell 2, and the inner ends of the pins 11 can be adsorbed due to the magnets I8 arranged on the inner side of the bottom shell 2, so that the pins 11 are not easy to fall off. Then the bottom case 2 is fixed on the wall through glass cement; or the bottom shell 2 is fixed on the wall through glass cement, and then the housing 1 is fixed on the bottom shell 2 according to the installation mode; when the advertising paper or the propaganda picture needs to be replaced, the pins 11 are adsorbed out of the first pin holes 9 and the second pin holes 10 by strong magnets, and the housing 1 is taken down for replacement. The installation between housing 1 and the drain pan 2, it is convenient to dismantle, novel structure is convenient for change poster paper or propaganda picture, easy operation, labour saving and time saving.

A light source may also be placed in the bottom housing 2. When the display board is used, the propaganda picture or the advertising paper is placed on the transparent panel, and then the propaganda picture or the advertising paper is illuminated by the light source, so that people can clearly browse the information on the display board.

In the embodiment, the transparent panel 3 is embedded on the outer side surface of the housing 1, and the magnet I8 is adhered to the inner side edge of the bottom shell 2 through AB glue; cardboard 4 passes through AB glue and connects in housing 1 bottom surface, and cardboard 4 stretches into the rear portion of drain pan 2, and is spacing between cardboard 4 and transparent panel 3 bottom drain pan 2, plays the solid effect of card. In other embodiments, the outer side surface of the bottom casing 2 is provided with a slot hole matched with the clamping plate 4, and the clamping plate 4 can extend into the slot hole to play a role in clamping and fixing the bottom of the bottom casing 2.

Further, as shown in fig. 3, in the present embodiment, a light guide plate 5 and a light strip 7 corresponding to a side surface of the light guide plate 5 are disposed in the bottom case 2; the outside of the light guide plate 5 is covered with a transparent film 19.

The light guide plate 5 is made of optical acrylic/PC plate material, and is made of material with extremely high reflectivity and no light absorption; the principle of the method is as follows: the optical-grade acrylic sheet is used for absorbing the light emitted from the lamp to stay on the surface of the optical-grade acrylic sheet, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is damaged and is emitted from the front surface of the light guide plate 5. Through various light guide points with different densities and sizes, the light guide plate 5 can uniformly emit light, and a point light source can be converted into a surface light source. The LED lamp has the characteristics of high luminous efficiency and low power consumption.

In this embodiment, in the bottom case 2, the rear portion of the light guide plate 5 is further provided with a back plate 6, and the light guide plate 5, the back plate 6 and the light strip 7 are all embedded in the bottom case 2. After the power is switched on, the light strip 7 emits light to each light guide point of the light guide plate 5, reflected light is diffused towards each angle, and then the reflected light is emitted from the front surface of the light guide plate 5 after the reflection condition is destroyed. Through various light guide points with different densities and sizes, the light guide plate 5 can uniformly emit light, the conversion of a point-line light source to a surface light source is realized, and the advertising paper is illuminated. Backplate 6 not only plays the shading, avoids the effect of drain pan rear portion light leak, is installing the utility model discloses during the show tablet, can coat glass glue or double faced adhesive tape on backplate 6 after, bond the show tablet on the wall body. The transparent film 19 plays a waterproof and moistureproof role, and does not influence the light scattering of the light guide plate 5.

Further, as shown in fig. 2, the bottom case 2 is surrounded by four U-shaped slots 12, and two adjacent U-shaped slots 12 are connected by a connecting member. In this embodiment, the space that is enclosed by four U type draw-in grooves 12 is used for placing accessories such as light guide plate 5, backplate 6, lamp area 7, has lightened the whole weight of lamp tablet, still plays the effect of hiding accessories such as light guide plate 5, backplate 6, lamp area 7 to reach pleasing to the eye effect.

Further, as shown in fig. 2, fig. 3, and fig. 4, in this embodiment, the connecting member is an adapter 14 matched with the thick bottom of the bottom shell 2, two ends of the adapter 14 connected to two adjacent U-shaped slots 12 are provided with socket strips 15, and the socket strips 15 are inserted into the U-shaped slots 12 and are fixedly connected to the U-shaped slots 12. Specifically, the socket strip 15 can be bonded with the U-shaped clamping groove 12 through glass cement, so that the assembly is convenient; the socket strip 15 is integrally formed with the adapter 14.

Further, the connecting member is a rivet 13 or a screw. In other embodiments, as shown in fig. 6, the connecting member is a rivet 13, and is fixed by using a rivet, so that the manufacturing is simple and the cost is low.

Further, as shown in fig. 5 and 7, the second pin hole 10 is a counter bore, and the outer end of the pin 11 is provided with a pin cap 16 matched with the counter bore. When the pin 11 is inserted into the second pin hole 10 and the first pin hole 9, the pin cap 16 at the outer end can be placed in the counter bore, so that the pin cap 16 is flush with the outer wall of the housing 1, and the pin 11 is prevented from being inserted out by others at will.

Further, as shown in fig. 1, a pressing strip 17 is fixed on the inner side edge of the housing 1, and a magnet ii 18 is fixed between the pressing strip 17 and the transparent panel 3. The pressing strip 17 and the housing 1 are integrally formed, and the magnet II 18 is bonded between the pressing strip 17 and the transparent panel 3 through glass cement. When placing the advertisement paper or the propaganda picture, the advertisement paper or the propaganda picture can be pasted on the transparent panel 3, then the advertisement paper or the propaganda picture is pressed on the position of the magnet II 18 by other magnets II 18 or the iron sheets, and the advertisement paper or the propaganda picture is fixed on the back of the transparent panel 3 by the suction force of the magnet II 18. Therefore, the advertisement paper or the propaganda pictures can be conveniently replaced.

Further, the light strip 7 is located on an inner side edge of the bottom chassis 2 below the light guide plate 5 or on an inner side edge of the bottom chassis 2 at a side of the light guide plate 5. In this embodiment, the light guide plate 5 is a side light-in type, and the light strip 7 is disposed on the inner edge of the bottom case 2 on one side of the light guide plate 5. In other embodiments, the light guide plate 5 may also adopt a direct-type light incident mode, the light strip 7 is disposed on an inner side edge of the bottom case 2 below the light guide plate 5, and an electric wire connected to the light strip 7 passes through the threading hole 20 from an upper portion of the light guide plate 5 to be connected to the power supply.
