Abstract

The invention discloses a frame carrier device and an LED display screen, and belongs to the technical field of LED display screens. The frame carrier device comprises a plurality of frame carrier modules arranged side by side; each frame carrier module comprises a first frame carrier unit, a second frame carrier unit and a base, wherein the second frame carrier unit is detachably connected to the base, and the first frame carrier unit and the second frame carrier unit are movably connected through a multi-connecting-rod lifting mechanism; and the bases of every two adjacent frame carrier modules are movably connected through a multi-connecting-rod angle adjusting mechanism, so that each multi-connecting-rod angle adjusting mechanism drives one frame carrier module to perform arc-shaped movement relative to the another frame carrier module adjacent to the one frame carrier module through a micro-metering adjusting piece with a scale mark. The frame carrier device and the LED display screen have the advantages of being large in angle adjusting range, high in adjusting precision, simple in structure, convenient to operate, capable of greatly reducing labor cost and machine using cost and the like.

Description

technical field [0001] The invention relates to the technical field of LED display assembly, in particular to a back frame device and an LED display. Background technique [0002] At present, large outdoor LED displays generally adopt the combination of back frame and LED cabinet, and the LED cabinet is supported by the back frame structure, while the traditional back frame, such as a Japanese character frame, has no angle adjustment device and is mostly on the cabinet. The installation of an angle adjustment device limits the adjustment angle. At the same time, most of the existing back frames are spliced ​​piece by piece, which is completed by manpower or other lifting machinery, which increases the cost of labor and the cost of using machinery. Contents of the invention [0003] The main purpose of the present invention is to provide a back frame device and an LED display screen, which aims to solve the problems of limited adjustment angle of the traditional back frame,...
