Title:
FRONT MAINTENANCE MAGNETIC ATTRACTION ANTI-FALLING MECHANISM OF LED DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2023/137902
Kind Code:
A1
Abstract:
A front maintenance magnetic attraction anti-falling mechanism (30) of an LED display screen, the mechanism being respectively connected to a base (10) and a display box body (20). The mechanism comprises: a housing (31), arranged on the end of the base away from the display box body and having an accommodating space gradually narrowed in a direction close to the display box body; a cover plate (32); a reset spring (33); a magnetic attraction member (34); a positioning column (35), one end of which passes through the magnetic attraction member, the housing and the base at the same time in a direction perpendicular to the cover plate, so as to restrict the magnetic attraction member to move in a direction parallel to the cover plate, and the other end of which is connected to the display box body; and stop balls (36), arranged in the end of the magnetic attraction member close to the smaller part of the accommodating space of the housing. When the magnetic attraction member is pulled by external strong magnetism to move in a direction close to the larger part of the accommodating space of the housing, the stop balls are separated from the positioning column, so that the positioning column can be pulled out so as to separate the display box body from the base. Thus, the magnetic attraction member can be effectively prevented from falling off, and the display box body can be conveniently disassembled and maintained.
