Assembly calibration device for LED screen

The utility model discloses an assembly calibration device for an LED screen, and relates to the field of display equipment. The assembly calibration device for the LED screen comprises a measuring plate, a supporting shaft is rotatably connected to the top of the measuring plate, a supporting plate is welded to the top of the supporting shaft, two fixing mechanisms are symmetrically arranged at the top of the supporting plate, and extension plates are rotatably connected to the two sides of the measuring plate through hinges. The assembling and calibrating device for the LED screen is simplein structure; two fixing mechanisms are arranged; therefore, the cross rod in the LED screen frame can be stably fixed between the pressing plate and the supporting plate; the cross rod is tightly propped against the support plate; the measuring plate is parallel to the transverse rod, when the LED screens are combined and spliced, the tops of the LED screens can abut against the measuring plate,so that the multiple LED s
