Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the utility model discloses a roof 1 of a rectangle sets up two fixed orificess 11 on the roof 1, and fixed orificess 11 includes that one is located centre bore 110, four minute holes of equipartition all around of centre bore 110. The user can fix the top plate 1 to the wall by using screw fixing of two diameters.

The number of the display panel 2 and the shutter 3 is 2 pieces, respectively. The display panel 2 and the barrier 3 surround the edge of the top plate 1, and one end of the display panel 2 and the barrier 3 gradually converges toward the other end. So that the utility model is of a ladder structure.

A window is provided in the middle of the display panel 2 as a display window 4. The display panels 2 on both sides are respectively provided with display windows 4. A U-shaped limiting groove 22 is formed inside the display panel 2. The stopper groove 22 is formed in an L-shaped plate to surround the periphery of the display panel 2. When the liquid crystal display is used, the liquid crystal display is slowly inserted along the limiting groove 22, and the limiting groove 22 limits the liquid crystal display to move.

The baffle plate 3 is provided with a plurality of vent holes 31. The vent holes 31 are arranged in a column, and a dust blocking eave 32 is arranged at each vent hole 31. The dust blocking eaves 3 are 1/4 arc surfaces and cover the vent holes 31.

The chassis base 5 covers the display panel 2 and the bottom of the bezel 3 using screws.
