Description

TECHNICAL FIELD

[0001] The utility model relates to detection device technology, concretely relates to a protective mask and detection device thereof. BACKGROUND

[0002] The LED leasing display screen is designed as a customized die-cast aluminum box, and the lightness, thinness and quick installation are the most important features. The lightness and thinness of the box body, the quick installation, removal and transportation adapt to large-area leasing and fixed installation application sites. The leasing display screen is widely used in stage leasing, various press conferences, exhibitions, TV Spring Festival Gala, important cultural activities of provinces and cities and other places. The leasing product has become the mainstream of the market, and installation and removal have become a normalized trend.

[0003] The existing protective mask detection device mainly focuses on evaluating the strength and various light emitting performances of the LED mask under static conditions, such as the diversity of light modes and the accuracy of brightness adjustment. However, for the leasing LED display screen that frequently changes sites, the transfer process becomes a challenge. When the display screen is disassembled and reassembled for transportation, due to the limitations of site conditions and equipment resources, the secondary protection measures often fail to achieve perfect state. Therefore, during the transfer, especially in poor road conditions, the stacked LED display screen may be damaged due to mutual collision and extrusion, thereby affecting the normal operation of the display screen. Unfortunately, the existing protective mask detection device fails to cover simulation testing in dynamic transportation environment, resulting in insufficient protection for the LED display screen during the transfer process.
