Document Type and Number:
WIPO Patent Application WO/2024/060069
Kind Code:

Abstract:
A protective structure and a digital television measuring instrument (1). The protective structure comprises: a display screen vertical edge cover (8), a display screen transverse edge cover (14), a first protective block (6), a second protective block (7), and a protective member; a limiting pushing spring (21) pushes a limiting plate (19) into a limiting slot (18), thereby limiting the protective plate (3), and preventing the protective plate (3) from moving; a guide rod (11) moves in a guide slot (10), so as to drive the limiting plate (19) to move towards a limiting pushing slot (20); when the limiting plate (19) is separated from the limiting slot (18), a winding elastic piece (32) drives a winding rope (13) to be wound, so as to drive the protective plate (3) to quickly move towards the second protective block (7); and when the protective plate (3) enters a protective closing slot (16), a fixing plate (4) comes into contact with a sponge pad (9), so as to cushion the protective plate (3) until a first magnet (15) comes into contact with a second magnet (17) to limit and fix the protective plate (3), such that the protective plate (3) is closed, facilitating protection of a display screen (2), and preventing the display screen (2) from being scratched by other tools.
