Abstract
The invention provides a forwards disassembled frame structure of an electronic white board. A light filtering strip is fixed movably by a first clamping strip groove of an upper cover and a supporting groove of a lower shell and can slide in parallel relative to the first clamping strip groove and the supporting groove; a locking portion of the upper cover is movably fixed with a fixing portion of the lower shell in a clamped manner; when the frame structure is disassembled, the locking portion is pulled to be far away from the fixing portion by an external force so that the upper cover and the lower shell can be separated from each other; the lower shell is movably fixed with an edge of a display region through a second clamping strip groove; and the second clamping strip groove can slide in parallel relative to the edge of the display region. In an overhaul process, the light filtering strip slides in parallel along the first clamping strip groove and the supporting groove, and then can be disassembled, and the locking portion is pulled to be far away from the fixing portion by the external force so that the upper cover and the lower shell can be separated from each other. A lamp tube and a printed circuit board can be overhauled after the frame structure is disassembled, the whole electronic white board does not need to be disassembled, and an overhauling process is simple and convenient and is easy to operate.
