Novel casing structure

The utility model provides a novel casing structure. The novel casing structure comprises a casing body, a main board PCB and an end cover, wherein the casing body is internally provided with a mounting chamber, one end of the casing body is an opening, the mounting chamber is communicated with an external environment through the opening, a pair of opposite side walls of the mounting chamber are provided with mounting grooves, the main board PCB is clamped in the mounting grooves of the side walls of the mounting chamber, and the end cover is used for covering the opening. The novel casing structure is provided with multiple mounting grooves which can be used for clamping the main board PCB and can be further used for locking a screw, so the use quantity of assembly screws is greatly reduced; the novel casing structure can be directly prepared by cutting aluminum sections, so other mechanical processing such as tapping is not needed, the novel casing structure is convenient to process, the processing period is shortened, production cost is saved, and the novel casing structure further has a small and attractive profile.
