Hoisting arc locks, adjustable angle displays and display walls

Abstract

This application provides a hoisting arc lock, an adjustable-angle display screen, and a display wall. The hoisting arc lock includes: a hoisting hook with a hook body and a holding end; a lock body including: a guide member with a guide groove, the hook body being rotatably connected to the guide member; a guide shaft with a guide portion cooperating with the guide groove, the guide portion having an arc-shaped end face; and a clamping device disposed on the guide member, one end of the clamping device abutting against the arc-shaped end face of the guide portion, the end face of the clamping device abutting against the guide portion being an arc-shaped surface; the guide shaft and the guide member are respectively provided with connecting devices for connecting to the component to be hoisted. According to the technical solution provided by this application, the hoisting and disassembly of the display screen can be quickly realized. Furthermore, by adjusting the angle of the hoisting arc lock, display screens with different arcs after splicing can be hoisted, and the length of the hoisting beam can be saved, thus reducing costs.
