Description

Novel LED display screen unit board magnetic pole that stretches out and draws back

Technical Field

The invention relates to the technical field of LED display screens, in particular to a novel telescopic magnetic column for a unit plate of an LED display screen.

Background

The domestic LED industry starts in about 1995, goes from single color to double color to full color, goes from large space to small space, goes through a long process, most of the installation modes are the magnetic attraction mode of the unit plate (module), but because the supporting structure on the back is the traditional iron square tube, because the square iron pipe is flat and low, the magnet is also a cold heading process, the precision is not high, the two things with low precision are structurally combined, the unevenness of the surface of the unit plate (module) is caused, the viewing effect is influenced, the surface is flat, only one magnetic column can be adjusted for about three times by adjusting the screw thread at the back of the unit plate (module), the adjustment is excessive, the adjustment is less and not flat, this wastes a great deal of labor cost and reduces the efficiency of the installation, and the conventional installation process has been continued from 1995 to the present, which wastes a lot of labor and affects the viewing effect.
