[0011] Further, in the utility model, the rear cover is integrally bent and formed by sheet metal, and the size of the rear cover is smaller than that of the front cover, so that the edge of the front cover can completely wrap the edge of the rear cover.

[0012] Further, in the utility model, the second screw holes and the third screw holes are vertically arranged.

[0013] Further, in the utility model, the pressing strip is made of insulating material.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The whole structure of the utility model can be fixed by screws, which greatly simplifies the assembly process and saves production cost compared with the structure of traditional multiple fixed frames plus screws and glue.

[0016] (2) The utility model adopts a pressing strip to connect and fix the liquid crystal, which not only prevents the influence of liquid crystal grounding on use, but also forms a buffer while fixing the liquid crystal to ensure that the liquid crystal is not damaged by jolting during transportation.

[0017] (3) The utility model adopts the design that the rear cover is slightly smaller than the front cover, and the edge of the front cover can completely wrap the edge of the rear cover after the front and rear covers are fixed, which not only reduces the overall thickness of the fire control room graphic display device to less than half of the traditional one, but also has a good protective effect on the internal circuit board and liquid crystal screen.

[0018] (4) The rear cover upper part of the utility model has a large space, which ensures that the mainboard has sufficient safe operation space and good heat dissipation effect after being installed. BRIEF DESCRIPTION OF DRAWINGS
