Abstract:
A corner protection device and an LED display screen that comprises the corner protection device. The corner protection device comprises a base (1) and a corner protection housing (2); the corner protection housing (2) is rotatably connected on the base (1), a first position-limiting clamping protrusion (11) is provided on the base (1), a position-limiting hole (21) is provided on the corner protection housing (2), and the corner protection housing (2) switches between a protection state and a folded state by means of rotation; when the corner protection housing (2) is in the folded state, the first position-limiting clamping protrusion (11) is located inside the position-limiting hole (21) so as to allow the position-limiting fixation of the corner protection housing (2); and when the corner protection housing (2) is toggled, the position-limiting hole (21) detaches from the first position-limiting clamping protrusion (11) so as to allow the corner protection housing (2) to rotate from the folded state to the protection state. The corner protection device solves the problem in which existing corner protection devices have complex structures and complicated operations.
